I am immortal with scientific thinking

Which one is the real... person? !
"Where the hell have you been? Wait, I see you!"

"Achen, what's wrong with you? Why don't you say anything when you answer the phone?"

"Achen, what happened to you? Are you okay? Speak!"

"What's wrong? Is the signal bad? Can't you hear me? Speak!"

"Why don't you speak?"

"Say something..."

"Please speak!"

"Say something!!!!"

beep--!!!
The phone was completely hung up at this moment. Lin Chen subconsciously took a step back, goose bumps suddenly appeared all over his body, and his eyeballs were full of bloodshot at this moment.

The surrounding environment suddenly became silent at this moment. Only Su Mu in front of him looked at him with concern, as if the voice just now was just an illusion.

This could be said to be the most miserable time since he was reincarnated into this universe. If he were really killed, he would be trapped in this world forever, and there would be no possibility of escape until after countless epochs.

Once it comes to that, he will be no different from being dead.

So no matter what, we can't completely die at the hands of these monsters, no matter what!
But which one is true now? !
"Achen, why are you here?"

At this time, another figure came running from the distance. Looking at his clothes, they were exactly the same as Su Mu in front of him, with no difference at all.

"Achen, what's wrong with you?" Su Mu in front of him asked with concern, as if he didn't hear the voice.

"Can't you hear someone calling me? Can't you see someone running over here?" Lin Chen stared at him and spoke word by word.

"Huh?" Su Mu was stunned when he heard that. He turned around and looked puzzled. "Did you not open the fume hood when doing the experiment, and inhaled too much medicine and had hallucinations? There are only two of us here, where did the others come from?"

Ok? !

As soon as these words came out, Lin Chen's eyeballs bulged out and he stared at him intently.

The other party can't see, this guy is fake? !
"You little brat, what are you doing here by yourself? Didn't you say you had a headache? Why are you running around everywhere..." Su Mu, who was running from afar, was approaching at this moment and complained, "I spent half a day looking for you..."

By yourself...alone?

They can't see each other?

'Chip, can you tell whether the two people in front are real? ! '

'Ding! Two images appear in the main body's retina, the auricle collects sound waves, and the eardrum vibrates, confirming that there is a sound source vibrating... The two people in front of me are definitely real!'

'Could it be an illusion?'

'The body secretes adrenaline and cortisol... It is judged to be extremely nervous, but no external unknown influence on the retinal nerves and auditory nerves... causing hallucinations in the bioelectric current... Preliminary judgment is that there is no supernatural hallucinogenic factor! '

Both are real, but they can't see each other, so there is only one possibility...

"Achen, are you okay?"

Both Su Mu came in front of him, with concerned looks on their faces, and approached him step by step.

The expressions of the two of them were exactly the same, even the imperceptible hairs on their faces, every facial muscle, every subtle expression... were exactly the same.

It feels like a puppet carved from the same mold!
"you you……"

At this moment, the expression on Lin Chen's face suddenly became extremely ferocious. Veins bulged on his face, and even his expression was a little distorted. His teeth were clenched and made a clanging sound due to excessive tension. There was panic in his trembling voice, and every byte seemed to reveal fear!

"Behind, behind!"

He pointed his trembling fingers behind the two Su Mu, as if he had seen something incredible, and his face was full of uncontrollable fear.

"Um?!"

The two Su Mu who were approaching were suddenly stunned, and subconsciously looked back, and then they saw...

Nothing at all.

"Ah, Chen, what's wrong?"

click-

At this moment, the head was completely twisted around. The two Sumu, one on the left and one on the right, turned their heads back to the front at the same time. Their facial muscles became extremely stiff and rigid, and the whole person looked like a lifeless yet "alive" robot.

It seems that this sudden panic was not in the program they recorded...

However, when they turned around, what they saw was a figure sprinting away at high speed.

Obviously, the sudden panic just now was just an act!

"As expected, if you don't gamble, you won't lose. Fortunately, I didn't believe any of them, because both of them were fake!"

Lin Chen quickly moved away from them, but the gloomy look on his face did not disappear.

It was obvious that there was not just one fake person, but a race, and for some unknown reason, they had targeted him.

Without any extraordinary powers, it is undoubtedly a pipe dream to use the strength of an individual to fight against a population.

'Trouble! What should I do now? It is absolutely impossible to resist head-on. I only have two lives in a month. I can't afford to waste time with them. I can only seek help from outside forces!'

'Call the police? No! Whether it's my girlfriend or Su Mu who wants to kill me, it doesn't make sense because they don't have a motive to kill me, and they are obviously smart. Plus, they are outnumbered, so they might delete the corresponding surveillance. If I say something at that time, they won't believe me without any evidence.'

'Of course, maybe this society has a supernatural management bureau, but it is probably not that powerful. This kind of race that can integrate into human society, possess intelligence, and can replace human disguises has first-class potential and harm. They should either be exterminated or strictly supervised, and they should not be able to wantonly kill a doctoral student in a top university in a human civilization city... At least on their side, they either don't realize the fake people, or they don't have the ability to deal with them! '

'The best way now is to make this matter bigger and make people believe it, but the problem is that I have to get in touch with the real upper class people in this society, otherwise in the process, the fake person quietly replaces the captain or official of a police force, and then I will fall into the trap! '

"But how can I, who comes from a small city, get in touch with the upper echelons of society..."

At this moment, countless thoughts flashed through Lin Chen's mind.

Go to the building in the city center, report on the official website, complain through the hotline... No, it's useless, at least it's impossible to get in touch with the real upper class.

According to common sense, the only people from the upper class of society that an ordinary person can come into contact with in his or her lifetime are... teachers in college!

Not to mention that the East China University where he is currently studying is one of the top ten universities in the Federation of Human Civilization, and the mentors he is in contact with are top authorities in the field of biology.

The connections of such a person... are definitely enough to establish himself in the upper class of this world's society!

"University teacher, I am a doctoral student... a professor! A member of the Human Civilization Federation Biology Academy!"

With this thought in mind, Lin Chen turned a corner.

And in his last sight, not far away, two Su Mu were standing there blankly, as stiff as puppets, with their heads tilted left and right towards the center, and a very stiff arc at the corners of their mouths. The key point was their extremely pale eyes, as if they were looking at some kind of prey, which made people feel creepy.

In just a flash, Lin Chen ran in one direction again, which was the direction he returned to the dormitory!

"You can't just say there is a monster, or the other party won't believe it. You must have evidence!"

Thinking of this, Lin Chen immediately turned back to his dormitory.

clatter! clatter! clatter!
The lights in the corridor came on along with the sound of hurried footsteps.

Before Lin Chen finally returned to the dormitory, he needed to hunt down his girlfriend to obtain evidence of the existence of the fake person.

Otherwise, if he went to the professor blindly and failed to produce any evidence, and instead let this fake person go into the dark, that would be the real danger. After all, he couldn't block the bullet coming from the dark!

"So the best way right now is to kill this fake person in my room first and use her corpse to speak!"

After realizing this, Lin Chen's face was filled with murderous intent!
Hey!
The footsteps paused at this moment, and Lin Chen stood in front of his dormitory. But when his hand was on the door handle, he hesitated to press it.

The sound...is gone.

When he left, the hurried knocking on the door...disappeared.

The other party is a fake person who is learning from humans.

But whether he was entering the house or escaping, he did not show the other party the skills to open the door. Even when he was leaving, the other party desperately banged on the door, but he did not learn to turn the switch.

So the fake person, at least the fake person trapped in his room, should not open the door.

But why is there no sound in the room now?
Did the other party learn to open the door when he was away, or was he hiding behind the door, waiting for the moment he opened the door... to kill him?

So right now... should I open the door or not?
Snapped!
The lights in the corridor were completely turned off at this moment.

A death-like silence once again enveloped the place. In the dimness, a figure was holding the door handle tightly.

The atmosphere at the scene was particularly heavy.

Because Lin Chen couldn't tell clearly whether there was a non-human being waiting for him inside the door.

To gamble or not to gamble?

The clock is ticking.

The lights came on again at this moment.

Lin Chen's hands pressed down little by little, exerting more force.

Snapped……

At this moment, the door opened.

call--

The night wind blows in my face.

The evening breeze, carrying a hint of chill, blew in from the balcony window.

The lights were on in the living room and everything was normal. The sound of running water came from the bathroom next to the kitchen.

The next moment, as if sensing someone coming back, the bathroom door was pushed open, and a number of white figures poked their heads out from inside.

"Damn it! When did you come back?!"

"Sumu..." Lin Chen's expression changed, and he closed the door casually, without any expression on his face, "Why are you taking a shower here?"

"Damn it, my phone and room card were stolen at some point, so I can only swipe the card to enter your room and stay there for a while. It happens to be hot, and I'm sweating all over, so I'll take a shower while I'm at it."

Su Mu walked out of the bathroom naked without any hesitation, and said casually:
"Is your headache better? If it is, you can play games with me tonight."

Lin Chen did not reply for a moment, but thought about it.

He locked the monster in the room, but Su Mu appeared in the living room. The original two were fake, but he took away the real Su Mu's phone number, and he could swipe the room card to come in... Could it be true?

"Okay, I'll go back to my room and start up the computer first."

Lin Chen responded, and seemed to really intend to go back to his room and turn on the computer.

But halfway through the walk, he suddenly stopped and asked with an inexplicable look:
"Sumu, have you heard of a monster? It can transform into a human appearance, but all its behaviors must be learned from humans. It will become more and more like that person in the process of learning, and finally completely replace that person..."

"A monster that looks like a human. You mean... a pseudo-human?" Su Mu thought for a moment and said, "Are you referring to that horror legend?"

"Horror... legend?"

"Yes."

Su Mu smiled at this moment. His teeth were very white and his skin was very smooth, which made him look particularly handsome with his delicate face.

But the smile at this moment makes people feel indescribable... weird.

"Uncanny Valley effect?" Lin Chen's eyes moved. "You mean... when robots are similar to humans to a certain degree, humans' reactions to them will suddenly become extremely negative and disgusting, or even fearful?"

"Yes, this uncanny valley effect seems to have been proposed in the last century, but in fact its origin, this deep-rooted fear, comes from ancient times."

"Our ancestors saw this kind of thing back then, and they were similar to humans, but different from humans."

"Legend has it that 10,000 years ago, humans had just learned how to make fire, ending the days of eating raw meat and drinking blood. Until one ordinary evening, a group of apes returned to the cave with their prey to make a fire."

"The fire drove away the wild beasts in the darkness, but it also attracted unknown monsters. Under the watchful eyes of the apes, a man walked in from outside the cave. His face was hidden in the darkness and could not be seen clearly.

"At that time, a clever ape-man walked over, raised a torch, and looked at the whole body carefully. Yes, it looked like the same species as himself."

"The apes in the cave welcomed him and celebrated the fact that their group had gained a new member. This was a way of surviving together. In the harsh environment of ancient times, population was a very important factor. Whether it was hunting or defending the tribe, one more person meant strength. However, our ancestors at the time did not know that the person who came in was not... their own kind."

"In the darkness, its facial features may be distorted, its limbs may be strange, or it may look the same as other people at first glance, but upon closer inspection, it seems to be out of tune with the people around it..."

"At first, our ancestors didn't care, thinking it was just a joke among their friends. But later, they realized that their thinking was wrong! And it was wrong in a very big way!"

“I call those things that look like humans but are not humans ‘pseudo-humans’. Because they are jealous of humans’ healthy limbs, beautiful facial features, and rich emotions, they start to hunt humans when they have the chance!

After killing a human, it will hide the person and absorb his appearance and voice, disguising itself as the original and living in his place. "

“Can you imagine that the person who just had a meal and a drink with you, went to the toilet, or just passed a corner, and was ‘hidden’ by those monsters?
"When we meet again, it seems as if nothing has happened. It chats with you and talks with you as usual... Only the feeling of being out of place that is revealed inadvertently makes you realize that the person in front of you who seems to be your "family" or "friend" has actually been replaced since some time..."

"Like now..."

Su Mu looked at Lin Chen at this moment, his facial muscles became extremely stiff and rigid, and the whole person was like a lifeless yet "alive" puppet, staring at Lin Chen
"——Can you tell whether I am a human or a fake one?"

Swah——

The surrounding lights seemed to dim at this moment, and the warm summer breeze brought a chill that seemed to penetrate deep into the bone marrow!

The atmosphere in the venue fell into absolute silence at this moment!

"Don't be ridiculous, this isn't funny."

After an unknown amount of time, Lin Chen suddenly spoke.

"Haha, this doesn't scare you."

Su Mu's face returned to normal and he smiled with a frown.

"It's just a horror story, isn't it?"

"Of course, this is just a legend..."

Before he could finish his words, there was a knock on the door. It was so dull, as if someone was pounding on the door with a fist, with no regard for any injuries.

The sound became more and more urgent, and the knocking on the door sounded more and more like dense drumbeats, accompanied by the sound of an access card being inserted into the door lock and trying to open the door.
