In the laboratory hall full of science and technology, a middle-aged man in a white robe is confronting a group of people through a sturdy reinforced carbon fiber glass.

Sirens are constantly sounding.

The man held a tube of potion in his hand, and looked coldly at the heavily armed security personnel who had arrived outside the glass, as well as the colleagues lying outside the transparent glass, wearing the same clothes as him and looking terrified, not minding that they were trying to force their way through the last security system of the laboratory.

Behind him, a device resembling a ship's survival pod was flashing red.

"Stop, you're going to die...... It's going to die...... This is the last R&D base on Earth, and all the hopes of Earth civilization are here, are you going to be a sinner for the entire Earth civilization?!" Someone on the radio kept shouting in a frightened voice.

The whole lab, everywhere is chaos.

But the middle-aged man in the white robe was not moved at all, no, there was still movement, he finally raised his hand and turned on the microphone.

"You were going to die, you were all wrong, from the day the Mars base and the asteroid belt space city collapsed at the same time, the civilization of the earth has ended. You don't understand, you really don't understand......"

"Han Xu, who said that he would die, as long as you complete the space-time travel cabin behind you, increase the power proportionally, and enlarge the cabin, everyone here can travel back, and we can use all the experience of the future generations to bring enough machines to rewrite the future of the earth in the former world......"

"You still don't understand...... the man shook his head, a strange smile appeared on his face: "You take it, I take it, and everyone takes the superbrain potion...... It's all poison...... New Humanity Project ...... It's already failed......"

There were some staccato speech, even pauses from time to time, but the man did not stop, and spoke faster and faster.

"The development of the brain domain does not depend on the endless development of drugs, I said when I invented the superbrain pharmacy that the balance in the biological body cannot be broken at will, the initial brain development must achieve a delicate balance with other organs of the body, through the endocrine system controlled by the pituitary gland, the whole body is strengthened over time, and then slowly further evolved, which requires human beings to slowly persist in order to finally succeed, this is the right reason!"

"But you must be anxious, the development of the brain domain has been completed at more than 50%, and the result of quick success is that the body will not be able to keep up, and the next step will be that the brain will compete with any other cells in your body for nutrients, no matter how much nutrients you eat, it is not enough...... You will feel that your thinking is getting clearer and clearer, and your horizons are getting wider and wider, but as long as you use your brain a little, even if you say a few more words, your body will immediately be very tired, and your immunity will decline rapidly...... Right?"

"That's right, we've solved countless problems with the New Humanity Project, built a Mars base, built an asteroid space city, but why did they collapse? Do you think we can completely cut off all communications? The aftermath of the New Humanity Project has finally exploded, right? The aftermath of the new generation of superbrain agents has finally exploded, right?"

The man kept asking.

"Don't talk about these things first, there are the smartest humans in the whole world gathered here, and there is a way to solve these problems after all! Han Xu, you hurry up and stop the space-time machine, this technology is not perfect, if you go back rashly, you will really die, if you turn on it with high power like yours, go back to the past that is too far away, the entire base will explode, do you want everyone to be buried with you?"

"Huh...... If you can't solve it, don't fool yourself...... Why don't I ask you a question, how long have you been...... When our brains are robbed of the nutrients for the embryo in the womb, we ...... Greed is the original sin of intelligent life, even if we know that the result of greed is the burning of jade, our brains are still uncontrollable!"

Speaking of which, the man's hands have obviously begun to tremble, and if you look closely, you can also see that the skin is aging at a rate that is visible to the naked eye.

"I'm overusing my brain again. Sighing in his heart, the middle-aged man simply closed his mouth, ignoring the stunned guys outside, the security system of the entire laboratory was re-encrypted by him, a new encryption algorithm, and it was impossible for them to enter the most heavily secured laboratory in history without half an hour.

Unless they use destructive weapons, but these guys who don't even dare to die, dare to make such a decision? They are all too smart! This machine behind him is the last hope of everyone in this base, as long as there is a glimmer of possibility, these people will not dare to use force against this laboratory, right? Han Xu laughed at himself in his mind.

Finally, the alarm sound in the laboratory stopped for a while, and a gentle female voice resounded throughout the hall: "Huiguang No. 2 Chong can be completed, space-time coordinates, Huaxia, YZ0000, 20180101, warning, component charge overload, this test may lead to SSS-level catastrophic consequences!"

Han Xu...... You're going to die...... All of !!! will die, all the survivors of the entire planet will die! you will be the greatest sinner in the history of the earth!" the roar on the radio was full of despair.

"History, people are dead, where is history? Hehe, on the contrary, you will be grateful to me...... , this bottle of potion in my hand is the most correct formula, but you don't listen...... The initial development of the brain and the body's resonance can only be 12.87653%, which is the most perfect...... Then it's time to evolve...... I will plant a seed, and let this hopeless planet run out of resources!"

After saying that, the man resolutely turned his head and boarded the space-time machine, and behind him were faces that had been distorted with despair......

The moment he lay down in the space-time machine, the man clenched the reagent in his hand, touched his pocket again, two tears slipped from the corners of his eyes, and muttered to himself: "You don't understand...... I used two bottles of reagents...... What I can see, you can't see yet...... Everyone went back together...... It can only lead to a catastrophe that will truly destroy the world! Where is the way out? Where is the debt that was once owed, where is it so easy to repay?"

"Boom ......"

In the huge roar, a ball of fire was reflected on the desperate faces, and the carbon fiber reinforced glass that could not be broken through before was torn to pieces by the huge impact like a piece of paper, and in an instant, everything disappeared, and at the same time, in the pull of the flames, the experimental cabin carrying Han Xu disappeared synchronously.

In 3018, the earth fell.
