The "brain in a vat" was first proposed by Hilary Putnam in 1981 in his book Reason, Truth and History.

The basic theory is:

A man (assuming yourself) was operated on by an evil scientist, and his brain was cut out of his body and placed in a vat containing a nutrient solution that kept the brain alive.

The nerve endings of the brain are connected to a computer, which is programmed to send information to the brain in order to keep it hallucinating that everything is completely normal.

For him, it seems that people, objects, and the sky still exist, and his own movements and body sensations can be input.

This brain can also be typed or intercepted from memories. He can even be coded and 'feel' himself reading a funny and ridiculous text here.

Human existence, in a sense, is at the service of one's own thoughts and the carrier of thoughts, the brain, and our feelings themselves are the various electrical stimulation signals received by the brain.

Or it can be said that our cerebrospinal fluid is the culture fluid, and the cranial cavity is a glass tank, and everyone's brain is a brain in some form.

This theory, Sora Yamaguchi himself understands, and even thought about doing this kind of experiment, to make someone a brain in a jar, but he didn't expect this to become the reality he himself suffered!

Sora Yamaguchi wanted to curse, but found that he had no vocal system at all, let alone a hearing system, and all he had was two lonely eyeballs that allowed him to see his miserable situation!

Even this ability to "see" can be regarded as Shen Feng's gift.

Once these two eyeballs are cut off from the Shen Jing connection to the brain, he will be completely plunged into eternal darkness, and he will no longer be able to communicate with the outside world in the slightest!

At this time, there is only one brain left, and even if you want to kill yourself, there is no possibility!

Sora Yamaguchi could only curse wildly in his own thoughts, cursing the devil-like man, cursing his cruelty and tyranny.

"Yamaguchi, in my eyes, you are nothing more than a self-pitying, self-righteous garbage, waste, and scum without the slightest humanity."

Shen Feng's voice suddenly sounded in Yamaguchi's head, but it was transmitted through the electric shocks and cables that connected to the brain.

Yamaguchi's mind calmed down from the initial anger and madness, and "said" to Shen Feng through brain waves:

"Kill me, all you want is an analysis of the evil spirit virus."

After understanding his situation, almost instantly, Sora Yamaguchi had already figured out what Shen Feng's purpose was for doing this, and what those dream worlds he had experienced before meant.

From beginning to end, the layers of dreams have only one purpose, which is to completely hypnotize Sora Yamaguchi's consciousness, and then set up the analysis of the evil spirit virus.

The other party is still working on preparing a healing potion for the evil spirit virus.

Now that he has fallen into such a miserable situation, and the other party's goal has been achieved, the only thing that can really free him is death.

It's just that Yamaguchi waited for a long time, but he didn't get a reply from Shen Feng, as if the other party had completely left.

He finally panicked and kept shouting in his head:

"Come back! Mr. Shen! Kill me! Kill me! ”

There was still not the slightest response.

Several nanobots next to them stepped forward and began to shut down some of the maintenance equipment next to them, while unplugging the wiring.

It seems to be a hospital somewhere on the edge of the Tokyo metropolitan area, and some of the equipment has the name and number of the hospital.

A nanobot opens a jar filled with culture and removes the electric shock and wiring attached to Yamaguchi's brain.

As a result, he is completely unable to communicate with the outside world and cannot receive any signals transmitted by the outside world.

There are only two lone eyeballs left.

"Mr. Shen, please! Kill me! Kill me! Please! You can't just leave! Kill me! ”

Yamaguchi screamed wildly in his consciousness, but from the outside, it was just a strange brain soaked in a tank of nutrients.

It looks like a diseased brain specimen soaked in formalin in medical school.

Then, under Yamaguchi's desperate gaze, a nanobot took several thick sheets of black tape, layer by layer, and wrapped the glass jar around.

Seeing the light and the scene outside being obscured a little bit, Yamaguchi's consciousness sank even deeper to the bottom, and shouted wildly in his head:

"Don't, don't do this! Please! Woo woo, please! You can't do that to me! You can't do that to me! Please, kill me! Please————"

He still didn't get any response, just layers of black tape that kept closing the jar, blocking everything outside.

Soon, all that was left for the pass was endless darkness.

No sound, no light, no touch, no everything.

There wasn't even pain.

Only the brain enclosed in endless darkness, and the consciousness imprisoned in it and the cries that he would never be able to hear.

But he is so awake that he can sense his own existence.

This is simply the most terrible punishment, a thousand times more cruel than the Infernal Hell.

After doing all this, a nanobot directly transforms into shape, completely enclosing the entire glass jar to form a solid metal shell.

Then, the metal room they were in began to transform like a wave, sinking underground.

There, there is a network of gray tides that spread throughout the Dongying underground, leading to China through undersea nanomechanical pipelines.

The jar, which contains Yamaguchi's empty brain, will be transported to a small courtyard on the outskirts of Hua Guotai City through a grey tide pipeline under the sea.

On the second floor of the small courtyard, Shen Feng took off the signal transmitter connected to his head, and his face was gloomy.

Jingwei, who was wearing a maid's costume on the side, brought a cup of tea and said to Shen Feng:

"Didn't you already get the analysis of the evil spirit virus, what are you doing with his broken brain? Make a spicy brain flower? ”

Shen Feng stood up, walked to the window, rubbed his face that was a little wrinkled due to lack of sleep, looked at the city in the distance, and said slowly:

"He has killed tens of millions of people, and may kill 800 million people, or even all mankind, I can't let him die so happily, since he wants to create a hell, let's go to hell first."

Although the analysis of the evil spirit virus has been obtained, it is definitely not that simple to prepare a healing agent for the evil spirit virus.

Whether it is serum or chemical agents, it takes a long time to complete the test completely, and there is less than a week left for human beings!

There are now nearly 800 million potentially infected people worldwide, and once the effects of antiviral serum imitations expire, these people will quickly turn into bloodthirsty zombies and continue to spread the virus to the rest of the world!

By that time, human civilization would still not be able to avoid the fate of extinction!

Jingwei smacked his lips and said, "Tsk, that's true, but as an artificial intelligence, it's still difficult for me to understand the collective nature of human beings, isn't it similar to destroying half of my core data?" ”

Then he looked solemn and said:

"The message of the Evil Spirit Virus has been passed on to those players, and I hope they can find the final way to solve it......"

Shen Feng nodded and said:

"I hope so, but I'm also going to be prepared for the worst...... I will do my best to cultivate the Grey Tide in the places with the highest number of infected people, and make decisions when the situation worsens, hoping to be useful......"

Then he smiled wryly and said:

"But in that case, it is likely to be directly exposed to the Whisperers, and there was still the Lord of the Void as a cover in Tokyo before, but this time I can only directly show the existence of the Gray Tide to the world...... With my current abilities, I am not at all strong enough to confront the Whisperers, which even the makers of the 'True Doomsday Game' fear...... Maybe this time, human civilization is really in trouble......"

Be completely infected by 800 million zombies and destroy human civilization around the world, or use the gray tide to stop the infection, and then be discovered by the whisperers and destroy the world.

Perhaps this is the choice that Shen Feng is facing now.

After the scene in Tokyo, Shen Feng was even more jealous of the whisperers, and he was extremely vigilant.

You must know that even the existence of the Lord of the Void has been intercepted by the Whisperers, which is enough to imagine what kind of existence the Whisperers are!

Once Shen Feng really revealed his clues, he would definitely be greeted by a stormy attack!

Even if he now has the big killer weapon of Gray Tide, in front of the kind of existence that transcends this universe or even this dimension, he is just a mantis arm as a car.

The strength of the gray tide itself lies entirely in its scale effect, and Shen Feng's ontology is the biggest weakness!

It's just that no matter what the outcome, he has to give it a go!

I only hope that those medical elites can find a way to crack the evil spirit virus as soon as possible, so that he doesn't have to go to the last step......

The appearance of the analysis of the evil spirit virus made a group of medical elites of the Salvation Army excited.

They naturally understand that this is brought by the commander again!

Then, with the tacit approval of the commander-in-chief, the people directly released these analyses to the world, causing an uproar, and then countries around the world began to devote all their efforts to research and development of a treatment for the evil spirit virus.

At this time, most of the general public is still in the dark, not knowing the effective time of the antiviral serum imitation, while the top leaders of various countries have fallen into a state of extreme tension.

Some countries have even begun to secretly build bunkers and select elites from all walks of life to prepare for mass evacuation in the event of another global outbreak of the evil spirit virus.

After all, although zombies can be killed by weapons, those ubiquitous viruses are difficult to prevent.

And even if a treatment for the evil spirit virus is finally developed, it will take several days to quickly mass produce it and inject everyone against the epidemic.

The time to go out to give birth and inject for epidemic prevention is less than two days left for human beings!

The rest of the time, start counting in hours!
