I loaded the dream game

Or maybe, the difference in the speed of time flow has not changed, and both worlds are moving forward according to normal time, and for both sides, there will be no sense of incongruity with "313"?

Two different events, yet they actually happened at the same time.

This kind of thing sounds contradictory, but even if we don't consider it at the "setting" level, there are examples of similar things in reality.

A theoretical concept emerged in Xia Zhi's mind...

"Master!" Seeing the young man in deep thought, Lilia couldn't help but grit her teeth and said dissatisfiedly: "Are you still thinking about what happened just now?"

What happened just now? What happened?

Xia Zhi, whose thoughts were interrupted, looked confused until he saw Eluke hiding behind Lilia, sticking out half of his head and looking at him shyly, then he reacted.

What's so strange about it? It's not the first time I've seen it... So, you're feeling shy now?

Xia Zhi complained in his heart, thought for a moment, looked at Lilia and said:

"I'm thinking about something."

"What's the matter?" Lilia's eyes were full of suspicion.

"Have you ever heard of the principle of black hole complementarity?"

Lilia: “……?”

Black hole...what's the principle? What is that?

She had a confused expression.

"To put it simply, there is a hole in the world that can keep everything from falling in and out..."

After thinking for a moment, Xia Zhi tried to give the girl a brief explanation in simple words.

"Because nothing can escape from it, we can say that this hole is isolated from cause and effect... However, the rules of the world dictate that information about things cannot be lost out of thin air, so they can only exist at the edge of this hole - a place called the 'horizon'."

"Now the question is," Xia Zhi continued, "if someone accidentally falls into this hole, what will happen?"

Lilia still looked confused... She hadn't even had time to understand the question, so how could she give an answer?

Fortunately, Xia Zhi had no intention of making things difficult for her, and continued to speak to himself: "There are two possibilities here..."

As he spoke, he stretched out a finger and said, "First, for the person who goes in, the edge of the hole, the horizon, is empty and there is nothing special about it. The spacetime in front of him is always continuous and flat. Therefore, as long as he can avoid being torn apart by the tidal force, he will pass through the horizon relatively intact and will not be destroyed until he reaches the center."

After a pause, he extended another finger: "The second possibility... For an outside observer, because the information of things must be preserved on the event horizon, he will not be able to actually fall into the black hole. Instead, he will appear to be stuck on the event horizon. The hot extended event horizon of the black hole will burn him and spread his information across the entire event horizon. Eventually, he will return to this world as the black hole evaporates."

Both possible outcomes are destruction, but they are obviously completely different facts.

"So, which of these two possibilities is true?"

Even if you ask me this...

Lilia felt that this question might be a little beyond her scope.

"It's very simple. Neither description is 'absolutely true', but they both really happened relative to their respective observers." Xia Zhi replied.

Although she got the answer, Lilia felt even more confused.

How could two completely different and contradictory things both actually happen?

"Have you forgotten what I mentioned at the beginning... That black hole isolates cause and effect. Therefore, for people inside and outside the event horizon, it is impossible for them to see the facts that each other sees..." Xia Zhi said, touching her head which was beginning to overheat.

This is one of the foundations of the black hole complementarity principle.

Two contradictions that humans cannot understand do not mean a real contradiction. Compared with objective reality, human thinking images are more restricted by the shackles formed in the process of evolution and growth.

Similarly, although the principles may be different, the situation between him and Ailu Ke should be similar... As for the specific principles and mechanisms, Xia Zhi does not intend to delve into it, as he is not prepared to do scientific research.

However, if this is the case, my initial guess that "the world where Ailuko is located will be forced to synchronize with my own body time" may need to be adjusted accordingly.

Xia Zhi thought about it and put the matter aside for the time being. He raised his head and looked at Eluke, who also looked a little dizzy after hearing his words. After thinking for a moment, he picked up the silver-white arrow again and tried to select her as the target.

[The target object does not meet the requirements]

Soon, the same prompt popped up in front of me.

It failed to work on two different objects in a row. Could it be that I really got a fake?

Xia Zhi couldn't help but complain in his heart.

"After saying so much, Master... you actually just want to change the subject, right?" Lilia seemed to come to her senses, and asked the boy with a suspicious look at 3.2.

Summer Solstice: ?

Traitor, how can you defame someone's innocence out of thin air?

Just as he was thinking this angrily, he felt someone gently pulling the corner of his clothes.

He lowered his head and met the girl's familiar crimson eyes.

"Summer Solstice..."

Ai Lu Ke looked up at him and asked expectantly, "When are we going to eat?"

"..."

Xia Zhi felt that the atmosphere he had just created with great difficulty seemed to be ignored by the two of them.

However, if Eluko said so...

"Let's go find Teacher Madoka first." Xia Zhi thought about it and made a decision.

By the way, let's find a chance to experiment with the effect of arrows.

He pondered this in his mind.

.......

Chapter 610: Can dating save the world?

"Mafuyu teacher~"

After seeing the familiar figure, Eluko quickly ran up with cheers, and before Kirisu Madoka, who had just turned around after hearing the voice, could react, he threw himself into her arms.

Kirisu Madoka was knocked back two steps by the girl before he managed to catch her steadily, luckily preventing her from falling to the ground.

This familiar way of greeting, even without looking down, she roughly knew who was rushing towards her.

"Eluko?"

"Yeah!" Ailuko nodded happily, raised his head and looked at her expectantly and asked, "Teacher Madoka, did you miss me?"

Facing such a lovely Eluke, even Kirisu Madoka couldn't keep a straight face anymore. She heaved a sigh of relief, stroked her hair, and said softly, "Of course."

"Hehe~"

Looking at the two people hugging each other after a long separation not far away, Xia Zhi sighed that Eluke and Teacher Mando really got along well. At the same time, he hesitated for a moment and took out the silver-white arrow again.

This time, he tried to choose Kirisu Madoka as his target.

And then the next moment...

[Are you sure you want to use it for the current target object? ]

Looking at the subtitles that popped up in front of him, which were different from the previous two times, Xia Zhi fell into deep thought again.

Being able to use it is of course a good thing, at least it means that what you got is not a fake, but... what is the difference between them?

Height? Race? Gender?

It can't be age, right?

Not far away, Kirisu Madoka, who was being hugged warmly by Eluko, shivered and felt an inexplicable chill. She couldn't help but look up and cast a suspicious look in this direction.

Xia Zhi seemed not to notice it. After thinking for a moment, he shook his head gently.

No, in terms of age, Lilia is a little younger than Teacher Madoka, and Eluk is much older than her... Teacher Madoka, who is between the two of them in age, should not be anything special.

Wait, speaking of special features...

Xia Zhi suddenly thought of something.

Could it be that... it has something to do with Mr. Mafuyu's identity as the "heroine"?

He thought for a moment, and his eyes fell on another girl who was standing next to Lilia not far away... If I remembered correctly, she seemed to be the child he had rescued from the ruins, right? She had grown up so much.

Xia Zhi sighed in his heart and reconfirmed his choice with her as the object.

[Are you sure you want to use it for the current target object? ]

The same prompt popped up in front of me

…It seems that this is not the reason.

Xia Zhi thought to himself with some disappointment.

"From just now on, you looked like you were thinking about something."

I don't know when, Kirisu Madoka has come to the boy's side with Eluko in his arms.

"Have you encountered something difficult to solve, Xia Zhi classmate?"

"I know!" Ai Luke raised his hand and answered.

"Xiazhi is thinking about that...hole...complementary...filling the hole thing, right?"

If you can't remember, don't force yourself.

Xia Zhi sighed slightly, reached out and took the girl from Teacher Zhendong's arms, rubbed her head and asked, "What do you want to eat later?"

"Steamed pork with rice flour!" the girl replied immediately.

I remember this very clearly.

"Go find Lilia and ask her to help you." Xia Zhi put the girl down and instructed her.

As for whether Lilia would do it or not, that had nothing to do with him. After all, he had already graduated, so he couldn't always come back to ask his master for help, right?

"It feels really hard to be your apprentice, Xia Zhi."

Looking at Lilia who was found by Eluk not far away and had a confused expression of "What is that?", Kirisu Madoka retracted her gaze and said to the boy next to her.

"Helping teachers solve problems is also one of the students' obligations." Xia Zhi replied.

is it?

Facing the suspicious gaze from Kirisu Madoka, Xia Zhi couldn't help but turn his head slightly.

Looking at the boy who seemed to be pretending not to see it, Kirisu Mafuyu sighed slightly and continued: "So, can you explain it? About why I suddenly came here again?"

"Teacher Madoka, haven't you always wanted to come here more often?" Xia Zhi asked, tilting his head slightly.

That being said...

“But I’m still grading homework.”

"It's okay to delay that kind of thing." Xia Zhi said nonchalantly, passing on his experience to her: "In fact, Teacher Madoka, you only need to correct the homework of the top ten students, and that's almost enough to correct the homework of the whole class."

According to his experience, there will be only some minor differences at most, and the duplication rate is probably above 95%, right?

"Xia Zhi, you seem to know a lot about this kind of thing?"

"Of course, but I am..." Xia Zhi was halfway through his words when he seemed to have just reacted and suddenly got stuck.

"Well...I did all my recent homework by myself." He tried to make amends and explain.

"Of course I know about that kind of thing." Kirisu Madoka said with a slight sigh.

Let's not talk about the objective questions for now, at least in terms of the subjective questions, the views on historical events and processes are extremely personal, and can even be said to be far-fetched... It's not eye-opening, but it can also be eye-opening.

Apart from this boy, Kirisu Madoka couldn't think of anyone else in the class who could write that kind of answer.

When she thought about it, she felt a little powerless.

Instead of giving the standard answer, could you at least express some safer opinions?

So... that's how we can come up with a solution to the world's problems.

She pursed her lips slightly and thought so in her heart.

"Don't worry, Mr. Madoka." Thinking she was still worried about the time issue, Xia Zhi comforted her: "Just like last time, it doesn't matter how long you want to stay in this world this time."

Kirisu Madoka was stunned for a moment.

That time it was 313 fingers...
