Genius Club.

Chapter 328 The Real Invitation
"Fuck!"

Even if Lin Xian was in heaven and earth, he couldn't hold back this frightening scene! He rushed to the bathroom glass door and jumped out.

It's terrifying!

What's going on!

The reflection in the mirror is out of sync with reality, which is already exaggerated and scary enough...

If I hadn't seen it wrong just now.

The hand holding the invitation to the Genius Club! It even stretched out from the mirror!
What kind of late night ghost story is this?

After all, Sadako came out of the TV. This can be barely explained from the perspective of physics, but the mirror is a reflection of light!

Objects in the mirror are virtual images.

How is it possible to actually get out from there?

not to mention……

The person who was out of sync with myself in the mirror just now and was smiling at myself was myself!
What if the person in the mirror is Lin Xian who has free will?

Who are you?
Is it the opposite of Tiangang?

……

Standing at the bathroom door, looking back.

Lin Xian discovered that the abnormality in the mirror had completely disappeared.

There is no one.

As always, the reflection of the clutter in the bathroom… the bottles and cans on the sink, the washing machine in the corner, the fallen stool on the floor, the towels on the shelf, and——

At this moment, it lies quietly on the porcelain basin of the wash basin, bright red as fire, with golden words...

Invitation to the Genius Club!

Lin Xian blinked.

It was incredible to see the invitation letter taken out from the mirror...

This goes against common sense and is totally incomprehensible.

Are you dreaming?
Could it be that... I was so sleepy that I fell asleep with my chin propped up in the bathroom?
So now I'm in a dream?
But he turned his head and looked at the electronic clock placed in the corner of the sink.

The time above shows:
【00:43】

"I won't dream at this time."

Lin Xian said softly.

He knew very well that in these 25 years of his life, his dreams would always wake him up on time at 00:42. Even if he fell asleep immediately afterwards, he would never dream again, unless it was 12:42 the next day, when a new dream cycle would begin.

"What exactly is going on?"

Lin Xian took a deep breath.

Then he carefully took a step into the bathroom and placed himself at the corner of the mirror.

Lin Xian in the mirror was also cautious and looked outside the mirror tentatively.

Lin Xian took two more steps forward.

Lin Xian in the mirror also took two steps forward.

Lin Xian waved his right hand.

Lin Xian in the mirror also waved his right hand.

"It seems to be normal."

But even though the mirror is normal now, Lin Xian's heart is still tense and he still feels anxious.

He glanced at the invitation letter to the Genius Club on the porcelain basin on the sink...

Its existence is the ironclad evidence of the terrifying and mysterious scene just now.

Even if the mirror is normal now.

It also cannot cover up the impact that the abnormal scene just now had on Lin Xian’s worldview.

He lowered his head again and looked at the digital clock.

Another light jump.

The time displayed above jumps from 00:43 to 00:44.

"So, the unscientific scene just now happened between 00:42 and 00:43, this one minute."

He inexplicably thought of the Seven Deadly Sins organization that Ji Xinshui and Ji Lin belonged to.

Although this organization may be misled, no matter what the process is, their rules for enforcing the murder of scientists are very strict and harsh.

Car accidents are necessary.

What is more necessary and difficult to control is the time of death of those scientists who were killed.

It is also the minute from 00:42 to 00:43.

Who set this time?
According to current speculation, there are two possibilities.

1. It was Copernicus, who was suspected to be a member of the Genius Club, who made the request to Ji Xinshui; so even though Ji Xinshui did not understand the deep meaning of this timing, he had to carry out this request blindly and rigidly as he was eager to join the Genius Club.

2. It was not what Copernicus asked for, but as Lin Xian and Ji Lin deduced and guessed, Ji Xinshui was blindly imitating the murder behavior of the Genius Club; that is to say, Ji Xinshui witnessed or knew about a murder committed by the Genius Club, which was carried out in a car accident at 00:42, so he imitated it strictly without knowing the reason.

……

In his confession when he surrendered, Ji Xinshui did not explain the reason and origin of the time of the murder, 00:42.

He just said that he would ask his men to strictly control the target's death time within one minute: 00:42-00:43.

When the police asked Ji Xinshui why it had to be at this time.

The unrepentant old man smiled strangely and said something meaningful:
“【Letting them die at 00:42 is the highest respect for them.】”

The female police officer who was in charge of the interrogation at the time couldn't help but call him a lunatic. Then, no matter how much she asked him about this issue, Ji Xinshui kept silent and just silently confessed his crime.

Lin Xian picked up the electronic clock.

Weighed.

so……

The time point 00:42 should really have some special meaning.

It is not just about the time when one's own dream ends and the time when the Millennium Pillar is born and disappears, but it is also closely related to certain behaviors and purposes of the Genius Club.

therefore.

No wonder, I received the invitation letter from the Genius Club at 00:42.

If it is really as Ji Xinshui said.

00:42 is a very noble time point, a time point full of respect... so it is reasonable for me to receive the invitation letter at this special time point. In fact, if this is a real invitation letter from the genius club, it must be received at this time point to have the most sense of ceremony.

He pondered again what Huang Que had said when he first posed the mirror puzzle to him.

It seems...

This invitation letter to the Genius Club is what Huang Que said she wanted most, so she reminded herself repeatedly in the mirror.

This is actually true.

Whether it was myself then or myself now, what I want most is indeed this invitation letter to the genius club.

At that time, I had just solved the seven deadly sins and was eager to know what kind of organization the Genius Club was, what it wanted to do, and what its nature was.

Now, I want to join the Genius Club, meet those so-called geniuses face to face, and see what they are up to. And... I hope to find out the truth about the Millennium Pillar in the Genius Club and save Chu Anqing!
Huang Que kept saying "mirror, mirror", and he indeed looked at himself many times and for a long time.

But who would have thought.

What she meant by looking in the mirror more often was to let herself try her luck and look in the mirror at 00:42 one day...

But at this point in time, it is too targeted for me.

When I first received the mirror puzzle, I was still in the third dream, parachuting and copying codes day and night, and waking up at 00:42 every day. So I had no time and didn't expect to have to look in the mirror at this time.

after that.

The third dream becomes the fourth dream.

I was even busier every night. Not only did I have to fall asleep at different times to test the tightness of the encirclement and the mysterious old man's reaction to different names, but I also had to check every day to see if the airship of Tam Bank had appeared. My dream schedule was fully scheduled every day, and I would have missed 00:42 when I woke up.

But that's not the point...

Anyway, even though it was a little late, I finally managed to solve the mirror puzzle.

But the problem is...

"Why is it a mirror? Why would such a supernatural event happen in a mirror?"

Lin Xian scratched his head, walked to the sink, and looked closely at the mirror.

Lin Xian in the mirror also leaned over, his eyes wide open, and looked into Lin Xian's eyes.

This is an ordinary mirror.

I have been using it for several years. It is as ordinary as it can be and as normal as it can be.

He went to the side again and confirmed.

Through the gap between the mirror and the wall, you can even see the tiles on the other side, which shows that this mirror is indeed normal and not a magic trick or anything else.

“This means that the key point is not the mirror, but the strange time point [00:42].”

"In this paranormal event, the mirror is only a basis, not a necessary condition, so it doesn't make sense to stare at it for any length of time other than 00:42."

"It has to be at 00:42 that the reflection in the mirror will become out of sync and able to cross the mirror surface, reach out and hand out the invitation letter to the Genius Club..."

He couldn't understand why the shadows, virtual images and reflections of light in the mirror could become real entities?
Lin Xian must come up with a scientific explanation for this matter.

He is a materialist warrior and cannot accept supernatural events. Moreover, the Genius Club is not a supernatural organization. They also abide by the laws of the universe and physics. At least for now, there are no supernatural abilities or extraordinary powers.

Even time travelers like Huang Que and millennium pilers like Chu Anqing are also restricted by the laws of time and space. Jask and Kevin Walker have never broken through the upper limit of human beings.

This incidates that……

“Existence is reasonable.”

"Since the mirror becomes strange at 00:42 and seems to be connected to another space... it means that it is allowed by the laws of this universe."

"Since it is within the law, it can definitely be explained by rules and laws."

Lin Xian rubbed his chin.

Think about this seriously.

Mirror, space, span, penetrate...

suddenly.

He suddenly remembered a concept proposed by Liu Feng——

[Space-time rift]!
Back in the laboratory of Tunghai University, when the two were discussing the question of how space-time particles came from external space-time to local space-time, Liu Feng said that space-time may not be completely isolated from space-time, and there may be some unexplained cracks on the wall of space-time.

It is precisely because of the existence of these cracks that time and space travel becomes possible.

Not only humans who have mastered a certain technology can travel from outer space and time to this space and time; space-time particles can also float over from space-time cracks and become outsiders in this space and time.

Then, let’s make some rigorous and extensive reasoning.

Since humans and space-time particles can pass through space-time cracks, why can't my arm and the invitation to the genius club pass through space-time cracks?
For an instant.

Lin Xian had an epiphany.

I feel like I have found the answer...

The concept of space-time rift is itself very abstract.

Lin Xian and Liu Feng couldn't clearly explain what the space-time rift looked like, where it was, and under what circumstances it would be discovered.

It's just because the description of "crack" is more straightforward and common, so the two of them called the path of this thing traveling through time and space a space-time crack.

But obviously.

The space-time rifts are not real cracks or breaks.

But it exists in other indescribable and incomprehensible ways.

Just like...

In front of me, the one who just scared me...

Mirror at 00:42.

"A crack in time and space."

Lin Xian muttered this concept:

"Perhaps the existence and appearance of the space-time rift is also related to the special time point of 00:42."

"Then if we think about it this way, what happened in the mirror at 00:42 just now becomes easy to explain if we connect it with the space-time rift."

Think of this.

Lin Xian couldn't help but breathe a sigh of relief...

Fortunately.

The supernatural incident just now seemed to be temporarily and barely explained by the theory of space-time rift.

Regardless of whether this theory is correct or not, it can at least prove that what happened just now was not some scary ghost story or supernatural event.

Human cognition is strange at this point.

Going into space, extreme sports, escaping life-threatening situations, fighting bloody battles with the enemy... many people are not afraid of these things.

However, no one seems to be truly immune to things like gods, demons, and monsters, no matter in ancient or modern times, in China or abroad, and they are always frightened by various true or false supernatural events.

"Forget it, let's not think about this for now."

As long as he was sure that he was still in a materialistic world, Lin Xian was not so terrified and accepted the theory of space-time rift calmly:

"Let's take a look at the invitation first. This time the invitation has been carefully selected by Huang Que... It is almost 100% certain that it is authentic."

He lowered his head.

Looking at the red invitation placed face up on the sink, he reached out and picked it up.

The feeling is completely different from that fake invitation.

You can feel the refinement and nobility as soon as you touch it. The plush edging craftsmanship used on the outside of the cardboard feels very comfortable.

The weight also seems to be heavier than the fake one, just a little bit heavier.

Lin Xian turned the invitation over and looked at the front...

The first thing that caught his eye was naturally the wax block that he was already familiar with and had touched many times, which was embossed with the seal and English name of the Genius Club.

This time, the round, flat wax block looked thicker and darker than the previous fake one and the one Jask gave him. I don't know why.

Is it the image of the bathroom light?

That shouldn’t be the case. The light in the bathroom is still very bright.

Perhaps because this is the real thing, the wax block made by Huang Que and Jask is more like a handicraft they made themselves, and is far less delicate, classical, and full of the charm of time than the current one.

Lin Xian pinched the wax block with his right thumb and index finger, lifted it upwards, and opened this long-awaited and hard-earned invitation.

"call……"

Lin Xian couldn't help but let out a sigh of relief.

I inexplicably felt a sense of heaviness and ritual.

He flicked his index finger, flipped the invitation completely over, and looked at the contents inside the cardboard—

"what?"

He blinked, unable to believe it:

"empty?"

Looking at the side, there is indeed only this bare page.

But why is there not a single word, not even a single symbol or a single pattern?

Lin Xian changed the angle again and looked at it carefully.

still none.

The card paper of this invitation is very high-end and delicate. You can see some light decorative patterns on the paper, which makes it look beautiful and elegant.

but……

Shouldn't a normal invitation letter include the basic names of the invitees, honorifics, invitation items, and the time and place of the party?

This is just giving yourself a blank invitation letter. What does that mean?
Even if it means taking 10,000 steps back.

This invitation is anonymous, and whoever grabs it gets it. But there should at least be a time and place for the party, right?
"Is there any omission? Are these geniuses reliable?"

Lin Xian was speechless.

What are you doing?

The invitations have been sent out, is there still a need to be a riddler?
"It shouldn't be so endless."

Lin Xian shook his head.

He suddenly thought of something...

This invitation letter is sent to myself by myself in the mirror.

So how do you get invitations to other members of the genius club?

Also through the mirror?

Was it also sent by their future selves in some certain time and space to their past selves through the mirror?
Considering the mystery of the Genius Club and its connection with time and space, this guess may not be incorrect.

Lin Xian firmly believed it from the beginning.

The invitation letter to the Genius Club is not easy to obtain, and it will definitely not be delivered by express delivery or a special person like sending a personal invitation.

That's indeed a bit LOW and not worthy of the name of the Genius Club.

But now...

Lin Xian also felt that using a mirror and letting his future self send out invitations was actually too advanced!
“Very genius.”

Lin Xian agreed:
"But it's also very abstract. Every member of the Genius Club must have a healthy and solid heart, otherwise they would have been scared to death by the mirror."

but.

This is also my own unfounded speculation.

Perhaps every member obtained the invitation letter in a different way; it is also possible that only I am special; it is also possible that I got this invitation letter through cheating...that's why the way I obtained it is so weird.

Because Lin Xian knows himself well.

No matter compared with any of Huang Que, Copernicus, Jask, or Kevin Walker, he is not qualified to join the genius club and is not qualified to receive this invitation letter.

He's really not a genius at all.

I haven't done anything earth-shattering.

At the age of 25, he does not have the leadership of Huang Que, nor is he as rich and smart as Jask, nor is he as ahead of his time as Kevin Walker, nor is he as elusive as the mysterious Copernicus... He plays with the seven deadly sins and the world's cutting-edge scientists at his fingertips.

Compared to these real geniuses.

Lin Xian admits that he is still too inexperienced.

"It's really possible that this invitation letter was obtained by Huang Que through cheating and backdoor... That's why he did it so secretly and shady, right?"

I can only ask Huang Que about this question when I have the chance.

Let’s think of a way to see if we can find the information hidden in the invitation letter.

After all, if you don't know the time and place of the party, this invitation is just like a blank piece of paper.

He folded the invitation again.

Only then did I realize that something was wrong with this wax seal...

【There's something hidden inside! 】

When he turned the page just now, the wax seal on the fold turned upright, and it was at that angle that it reflected the incandescent light above his head, allowing Lin Xian to notice through the warm red light that there was a black unidentified object sealed in the wax block.

No wonder this wax block is unusually thick and a little larger than normal.

Lin Xian unscrewed the wax block completely.

Take it in your hand.

He raised it above his head and looked towards the white light.

"really."

He narrowed his eyes.

In the middle of the red wax block, there is indeed a vague black object sealed in. It is roughly oblate and not that thick, but it is hard to see what it is because the wax seal is made of a mixture of rosin, paraffin and tar, and has very poor light transmittance.

"Let's open it and see."

Lin Xian now has three wax blocks with the seal of the Genius Club in his hand. They are no longer precious things. He even made copies himself, so he can tear them apart at any time without feeling bad about it.

He took a small screwdriver and began poking at the wax nugget.

Be very careful and slow, for fear of damaging the things inside.

It took several minutes.

Lin Xian finally removed all the sealing wax on the outside and took out the sealed things intact.

It was a bright gold badge, a standard round shape, slightly larger than a one-yuan coin, and not much different from the badges people usually pin on the left chest of their suits. There was also a small pin on the back, so it was definitely a badge.

“Is this a true invitation, a token of trust, a symbol of status?”

Lin Xian flipped through the golden badge.

It is much heavier than expected. It is most likely made of gold, but it is probably not pure gold.

Because pure gold is too soft and easily deformed, it is rarely used to make delicate decorations such as badges.

So... this should be an alloy of some kind of material with a large gold ratio, so it feels heavy in the hand.

Whether it is front or back, it is a uniform bright gold color.

On the front of the badge, unsurprisingly, the seal of the Genius Club is engraved in raised relief.

The back of a hand with the right index finger extended and pointing straight to the sky.

Then, at the bottom of the wrist, the English words "Genius Club" are also embossed.

"I see……"

Lin Xian held the golden badge that symbolized membership in the Genius Club. It seemed that his guess was correct. This was the real invitation letter.

That's why Jask gave himself a fake wax block.

If he gave himself that badge... I'm afraid he wouldn't be able to attend the Genius Club party?

But now, new problems arise.

What can a simple golden badge prove? This kind of exquisite craftsmanship is not difficult to imitate, not to mention that it is a question that makes Lin Xian feel tired and anxious.

What's the time and location of the party, bro?
How do you meet and hold meetings?

Lin Xian clenched the golden badge in his palm, then picked up the chair that had been kicked off the ground, sat on it, and began to think about the details that he had overlooked...

First of all, as I just thought, this golden badge should not be a simple decoration.

Because it is too easy to fake.

Using this thing as a status symbol for members of the genius club would be too crude and un-genius.

Secondly, Lin Xian also wondered whether there were some electronic components inside the badge?
But the badge is too thin to accommodate even the smallest and thinnest button battery.

Finally, he checked carefully many times and found that there were no hidden buttons, hidden spaces, or hidden information on the badge.

So……

Is there any other method?

It does not require electricity supply, does not destroy the original structure, and can store enough information in the badge so that the invited person can read it?

suddenly.

Lin Xian opened his eyes:

“[NFC].”

He thought of the community access card, his second-generation ID card, the meal card of the university cafeteria, and the Donghai City’s former bus and subway card!
There is no battery supply in these cards.

But they are all NFC devices. As long as they are close to a dedicated reading device, the magnetic field generated by the reading device will induce internal voltage, which in turn forms an electric current and transmits data.

This is the principle of electromagnetic induction coupling technology, which is widely used in daily life.

Access cards, ID cards, meal cards, bank cards, transportation cards, membership cards, and even Nintendo's amibo toys...all use the NFC principle, which can store data and transmit information without the need for active power supply.

"So, this golden badge is most likely a small device similar to an NFC access card! Just bring it close to an NFC reader to read the information inside!"

Lin Xian took out his cell phone directly from his pocket.

Nowadays, most mobile phones already support NFC card swiping function and can even simulate NFC signals. It is no longer a high-end technology.

Of course, the NFC simulator of a mobile phone can only simulate some simple, unencrypted NFC signals, such as access cards.

Don't even think about simulating NFC signals like encrypted meal cards, bank cards, ID cards, etc. It's very difficult. The higher the encryption level of NFC, the more difficult it is to crack and copy.

After taking out the phone.

Lin Xian directly brought the golden badge close to the phone——

beep.

The phone made a slight sound and automatically recognized the NFC signal. Then the browser APP popped up and started jumping to web pages continuously.

"Guessed it right."

Lin Xian chuckled.

Although this isn’t a very difficult puzzle and isn’t something to be proud of, at least I guessed it right, and I’m one step closer to attending the Genius Club gathering!
On the mobile phone screen, the web page keeps jumping, and I don’t know where it will eventually jump to.

Lin Xian suddenly had an idea.

If VV is still there, can we find the headquarters of the Genius Club by tracking the signals of these web page jumps?

In theory it should be possible.

but……

Considering the existence of Kevin Walker, the most powerful hacker on earth,

VV, which has been iterating and evolving for half a year, is still unable to track down Kevin Walker's address and true identity.

and so.

If this NFC identification system and network jump logic were designed by Kevin Walker, then VV, which is now severely damaged, would find it difficult to find the source of the server in a short time.

After all, the genius Kevin Walker is too strong.

He can defend against super artificial intelligence 600 years from now. He is so powerful that it is unimaginable.

However, Lin Xian doesn’t care where the Genius Club’s headquarters is for the time being.

We will consider these things after VV is resurrected.

His primary goal now is to attend the gatherings of the Genius Club in person and face those geniuses.

Gather intelligence, look for clues, and eventually... eliminate Kevin Walker, even Jask, and even the mysterious old man in the fourth dream. In short, all enemies will officially enter his sight.

And when he has resolved the current crisis and ensured that no one can threaten VV's existence, it will be time for him to resurrect VV.

With the return of his old friend, his combat effectiveness will increase several times.

Until then.

What exactly is the nature and stance of the Genius Club... In short, I must become strong and have the ability to fight against them.

After all, my ultimate goal is to rescue Chu Anqing!
A real man should stick to his word.

Since I promised Chu Shanhe, I must bring Chu Anqing home.

Then.

No matter who he was about to face.

Be it the Genius Club, the laws of time and space, or an enemy even more powerful than the laws of time and space.

He will also try his best to get Chu Anqing back!

at last.

After several minutes of web pages constantly jumping, the content on the web page finally appeared.

It was a website with extremely simple design, reminiscent of the BBS online forum style of the 1980s.

The interface is pure black, with a line of white text in the middle:
【Please enter any space-time coordinate. 】

This is obviously a question.

Then below the question, there is a rectangular white text box where you enter the answer; to the right of the answer box, there is a gray OK button.

This is……

An exam?
Lin Xian looked at the top of the webpage and saw a 1/3 logo.

This probably means that there are three questions in total that need to be answered. Now you are answering the first question. Only when you answer the correct account number can you see the second question.

Below the answer box, there is a line of small white text:
【Genius never makes mistakes, so you only have one chance. 】

……

Lin Xian stared at the web page.

He probably understood the real process of joining the Genius Club.

To put it bluntly, an invitation letter is just a stepping stone and an admission ticket.

If you want to truly join this mysterious organization, you must complete three tests.

Perhaps only after answering the three questions correctly will I be truly invited to join the Genius Club, learn the time and place of the gathering, learn the club's rules and precautions, and then I can officially meet those incredible geniuses.

“The threshold is really high…”

Lin Xian is now 80% certain that this invitation letter was definitely sent by Huang Que through a backdoor or cheating method.

The first test question:
【Please enter any space-time coordinate. 】

hard to imagine.

What exactly is the problem here?
What are space-time coordinates?

Why ask this question?

Moreover, there is only one chance to answer.

It seems that if I answer incorrectly this time, I will lose the qualification to join the genius club forever.

"Space-time coordinates."

Lin Xian pronounced this new term.

He couldn't understand.

But there is no doubt that this question can confirm my previous guess...

The Genius Club is indeed related to time and space.

Perhaps they really have mastered the power to manipulate time and space, so they can ask a reserve member such an arrogant and arrogant question as "time and space coordinates".

Then I thought about the strange way in which I got the invitation, the space-time rift, and 00:42, all these messy events mixed together.

Lin Xian increasingly felt that the power of the Genius Club might be far beyond his imagination.

They even figured out the space-time coordinates.

Then the act of sending the invitation through the mirror and the cracks in time and space may not be abnormal.

Lin Xian closed the web page on his mobile phone.

He would not waste this one and only chance, his only hope of joining the genius club.

There is only one chance to try and fail.

Therefore, he would not try it easily before he was completely sure what space-time coordinates were.

“That’s something you need to ask a professional.”

Lin Xian held the golden badge and whispered.

……

the next day.

Tunghai University, Rheinland Joint Laboratory.

"Liu Feng, what exactly are time-space coordinates? How do you understand them?"

Lin Xian did not tell Liu Feng about the invitation to the Genius Club and the mirror, but directly asked about the understanding of space-time coordinates:
"Does every different time and space have a different number?"

Liu Feng thought hard for a while and shook his head:

"probably not."

"People in each time and space have no communication at all, and there is no way to communicate. Each time and space believes that it is the main time and space, and that it is the original timeline. How can they be numbered? There is no reference point at all."

He picked up the chalk, came to the blackboard, and drew several divergent rays starting from a small point:
"In the world line theory, different choices at each node will lead to different world lines, leading to different futures and creating different possibilities... Under this theory, the initial world line will generally be named the α world line."

"So, if some behavior or action on the α world line affects the future direction, it may shift to the second world line, which is the second possible future. We generally call it the β world line."

"Similarly, the third possible future is the γ world line; if other possible futures can be split out, then that is the δ world line..."

"These four Greek letters, Alpha, Beta, Gamma, and Delta, actually don't have any special meaning. They just distinguish several world lines. If you want to save trouble, you can even directly call them the first world line, the second world line, the third world line, the zeroth world line, and so on."

Lin Xian nodded.

He could understand this point without Liu Feng explaining it.

Isn’t that how he named the different future dream worlds?
The first dream, the second dream, the third dream, and the fourth dream are actually completely consistent with the theory of world lines.

"So, you think that these Alpha Beta, or the first and second, are space-time coordinates?"

"No no no."

Liu Feng waved his hand:
"How can it be that simple? These are all subjective names and are not universally applicable. Think about it, what is the concept of coordinates? It is similar to longitude and latitude. Each coordinate point is unique. For example, the longitude and latitude of Donghai City is 31 degrees north latitude and 121 degrees east longitude."

"This is the [coordinate] of Donghai City. It is unique on Earth and there is only one such coordinate. When it comes to this coordinate, only Donghai City fits the definition. This kind of unique accuracy meets the definition of coordinates."

"So, if you must explain the concept of [space-time coordinates], then I think its expression should be similar to longitude and latitude. It must be unique and accurate. As long as you say the coordinates, you can immediately locate a specific time and space without any objections or deviations."

"That's what I think too." Lin Xian said:
"But if we want to know the space-time coordinates of a certain space-time, how can we do it? We don't need a specific one, just any one will do. It's just like longitude and latitude. I can just say a longitude and latitude, and as long as it's within the range, then this coordinate must exist on the earth."

"That's true." Liu Feng agreed:

"If you want to know the coordinates of a certain spacetime at will, then we only need to find the arrangement, naming, and combination rules of the spacetime coordinates. As long as we know the rules and range, you can make up a coordinate number at random, and this spacetime will definitely exist, just like longitude and latitude."

"For example, let me just say 22 degrees south latitude and 43 degrees west longitude. Which country or city is this? Lin Xian, do you know?"

Lin Xian shook his head:
"I don't know, but it certainly exists on Earth."

Liu Feng ran to another lab table, took out a globe, turned it half a circle, and pointed to the location of South America:

"Found it. Rio de Janeiro, Brazil."

"So now you understand, right? If your goal is to describe any space-time coordinate, then you only need to understand the definition form, rules, and numerical range of space-time coordinates."

"I know this truth. You don't need to explain it to me."

Lin Xian spread his hands:
"So, what should we do? How can we know the rules for defining space-time coordinates?"

hum~
Liu Feng smiled evilly, walked back to the experimental table, and tapped the time clock that still showed 0.0000000:

"I think this space-time clock might be able to help you!"

"Because its function is to test the curvature of space-time, isn't it? Just like every longitude and latitude must correspond to a certain location on the earth..."

"[Each space-time curvature may correspond to a specific space-time!]"

……

Lin Xian turned around and looked at the time-space clock that he had always been pessimistic about:
"Isn't your statement a bit imprecise? If any seven decimal places after the decimal point represent a space-time coordinate, can't we just make it up? For example, 0.1234567? Does this count as a space-time coordinate?"

"I'm not sure." Liu Feng shook his head seriously:
"It may be, but it may not be. Because we don't know the law of space-time curvature, how many decimal places it has, or what the smallest value is."

"But I think it's a good idea to calculate and analyze space-time coordinates through the curvature of space-time. So... are you anxious to know the answer? If not, why not wait until the numbers on the space-time clock change one day?"

Lin Xian looked at Liu Feng.

There was no sound.

A breath slowly came out of his nose...

in a hurry.

how to say.

He was definitely anxious. He couldn't wait to answer the three questions of the Genius Club correctly and then attend the Genius Club party.

But this kind of thing obviously cannot be rushed.

Because he only has one chance to try and fail, he must make sure that there are no mistakes.

"Is there any other solution?"

Lin Xian rubbed his chin and thought:
"We can't bother Yellow Bird again, can we?"

The person who tied the bell must untie it. The oriole gave me a hint about the mirror puzzle, and maybe it can also give me some hints about the time and space coordinates.

only……

Thinking of the day when the oriole was in front of him, being strangled by the throat by an invisible force, being attacked by the laws of time and space, and his whole body became transparent and painful...

"Forget it, Liu Feng, we will solve this problem ourselves."

Lin Xian raised his head:
"We can't bother the Yellowbird anymore."

"Ah, Huang Que's words..." Liu Feng had only said half of his words when the sound of high heels coming from the door interrupted him:

"Are you looking for me?"

Lin Xian turned around.

I saw the heroic Huang Que, with her blue earrings shining in the sun. She folded her arms, just like when she first came to this laboratory, leaning against the door frame naturally, smiling and looking over here:
"Lin Xian, long time no see."

Lin Xian looked at the time traveler standing in the sun with a complicated expression. His eyes seemed to have dimmed a lot:
"It's strange, why is it that every time I want to see you, I can always see you immediately."

Huang Que heard this and smiled:

"Isn't the reason obvious, Lin Xian?"

She raised her head and used her right index finger to push the hair on her cheek behind her ear:

"Because I've been waiting for you."
