Even if the earth is really occupied and the earthlings are really dead, that is, the three-body people erase all the information of the earthlings, but the information of the stone walls buried underground cannot be erased.

Maybe in the future, it will be excavated by archaeology, and I know that there was such a civilization on the earth before, and there was such a person in the civilization who lived.

Zhang Xuan is very interested in these, if a creature can replicate its genes indefinitely, it will not be damaged.

Jellyfish, for example, can choose not to reproduce and live forever on its own.

Of course, creatures that do not have the ability to live forever can only prove that they have come to this world through reproduction and genes, which is the instinct of all living beings.

And now, the earthlings not only do not have the ability to live forever, but even the possibility of keeping their genes passed on is close to zero, and the three-body people will not let go of the earthlings.

Therefore, the only thing that human beings can prove that they have lived is a stone tablet engraved with a text.

Zhang Xuan has read the book of life and death, and knows how the living, the king of Hades, looks at the dead, and the living go to write an epitaph for themselves, which is interesting.

Most people will make two revisions, the first epitaph, only about their own merits and good deeds, but considering the extinction of earthlings in the future, they will make a second revision.

And this time the revision is relatively objective, and will say what they regret, as well as the desires they hide in their hearts, it is amazing, they say what they think.

To tell the truth, to be sincere with oneself is already at the level of clarity in the path of monasticism.

And such people are still increasing, as long as there are exercises, and with a little bit of allocation, these people will quickly enter the ranks of earth immortals.

But it's a pity that Zhang Xuan doesn't want to preach to these people, because even preaching is useless, and they are destined to be unable to break free from this universe.

The vast majority of these custom steles are elderly, with declining physical functions, many diseases, and their lives are short.

These are just the twenty years of the crisis era, the corner of society, all of this, very interesting, in the eighteen layers of hell, there is no such torture - waiting for death and torture.

Hines and his wife, Keiko Yamasugi, continue to work on the brain, hoping to unravel the mysteries of the human brain and build new computer networks and algorithms.

Proposition 1: Coal is black. Proposition 2: The temperature in winter is lower than in summer. Proposition 3: The Moon is a satellite of the Earth. Proposition 5: Triangles have stability.

The appearance of each proposition causes the subject's brain to make these judgments, and through the simulation of the supercomputer, Hines knows which neuron is at work.

It's not that I don't want to come up with some difficult questions, it's just that difficult questions, the more neurons are needed, the more difficult it is to observe, and these simple questions require fewer neurons.

From shallow to deep, with the increase of data, the mechanism of the human brain is also clearer, but today there is a small problem, a subject suddenly developed cognitive impairment.

"What's wrong with him? Lips so dry? Give him water! ”

Hines frowned, but the subject looked at Hines with a look of resentment and shouted:

"Are you going to kill me? Water is poisonous! ”

"Cognitively impaired?"

Hines looked at the doctor, who shook his head and said:

"No, we have done physical and psychological tests on all subjects in advance, and his other behaviors are normal, but he suddenly thinks that the water is poisonous!"

Keiko Yamasugi took out the subject's data for the past two days and found that he was indeed afraid of water, did not drink drinks, and the food was completely dried before eating, and even with his own sweat and blood, he was also extremely afraid!

"If he was normal before, then it can only mean that our experiment was wrong, and people can live for five days without drinking water, so take out all the experimental data of his seven days, and we will re-check!"

Hines is not wrong in his inference, in his proposition number 175, water is poisonous, the feedback received is false, and this proposition is false.

However, in the operation of the computer, it is an overdose of intensive scanning, which makes this proposition forcibly changed to a true proposition, that is, for the subject, the proposition that water is highly toxic is true.

In the second experiment, Hines did it himself, and he also changed his perception that water is highly poisonous to a true proposition, and the same hydrophobic symptoms reappeared.

"Honey, do you really think water is poisonous?"

Keiko Yamasugi grabbed Hines by the shoulder tightly and said:

"You know, life is inseparable from water, and your body is 70% water!"

"Yes, I know that 70% of my body is water, and I also know that water is highly poisonous, and I am dying because I am poisoned by water, but my memory tells me that there is no need to worry!"

Hines said sadly: "It's very contradictory, my cognition is rapidly collapsing, my world is rapidly declining, and I feel a huge death!" ”

However, after testing again and revising the proposition, Hines returned to normal, but the world was completely different to him.

After further research, Hines finally created a new technology, that is, the thought seal, which is a technology that can change people's thinking and cognition.

Most countries are opposed to the idea stamping technology, even though they have already exercised overwhelming thought control.

Countless commercials tell you what you buy to be successful and what you have to have life, and this consumerist trap is everywhere.

Countless advertorials tell you what you have done to be a truly independent woman, to what extent you control men, and how much a woman has truly gained love.

"In the context of the question of whether humanity is now confronted with the question of survival or destruction, I think that there is no point in considering whether the mind is free or not, and that we must expand those who believe in the victory of humanity! Even if it's mandatory! Hines said.

Mankind has invested huge manpower, material and financial resources in the space defense system, but the effect is not satisfactory, and a larger and larger intellectual barrier has appeared in technology.

The material of life has also declined to 50 years ago, a new wave of defeatism is surging, and the first children under the three-body crisis have grown up, and they are under great pressure.

Newborns are decreasing year by year, the population is aging rapidly, and all this can lead to a total rout of the defense plan!

Therefore, in the end, the conference adopted the ideological steel seal, which only allows those in the space force who voluntarily accept the belief that mankind will win, and can only accept the ideological steel seal of human victory.

In the beginning, many people came to ask, some people wanted to believe that their wives were not cheating, some people wanted to believe that their lovers were not actually dead, and some people believed that they would succeed.

These messy beliefs are naturally impassable, which is illegal, but after that, it has gone much smoother, and many space forces have come to accept the ideological steel seal, and then return to their posts.

Things are on track, and Hines and his wife Keiko Yamasugi hibernate again, go to the future of technological innovation, and continue their own wall-facing plans, and the wall-facing people don't need to explain their plans.

However, even though the law prohibits it, the idea of steel stamping technology is still spreading rapidly in the black market, and the more difficult the era, the more firm belief is needed.

After Nurman Rediaz woke up, in addition to governing his own country, he also supervised the construction of a stellar nuclear bomb, and the supercomputer had already calculated the model, and it only needed to be built step by step.
