Wang Han has seen in the cinema more than once that the end is coming, there are natural disasters, meteorite landings, alien invasions, zombie mutations, etc., and human beings are dying out in various ways at the hands of Hollywood directors.

But I never thought that the end would come so quickly, and that it was not only human beings who would perish, but the whole world.

I still remember that when mankind first identified the signal of an extraterrestrial civilization, the whole world celebrated, and they even awarded the Nobel Prize to the discoverer.

At that time, it was proposed that mankind entered the countdown to extinction, and since ancient times, when two civilizations intersected, one always annexed the other, and human beings could be destroyed or enslaved.

Optimists, on the other hand, believe that the earth's technology is enough to protect itself, and that the world's nuclear bombs can blow up the earth's core, and that they are afraid of foreign invaders?

Besides, the discovery of extraterrestrial signals does not mean that they are already on their way.

However, only three months later, a dense alien fleet appeared in outer space, and mankind knew that in the face of alien civilizations that had mastered space jumping technology, the existing scientific and technological power of mankind could not resist at all.

They don't negotiate, they don't communicate, they fight when they come up, all animals and plants are assimilated, and the human soldiers who are still fighting up one second will become their kind the next second, turning around and dealing with humans.

The greenery of the earth, large swaths of withering, were replaced by gray-brown vegetation and large purple-red plants. The blue waters are gradually turning green, and strange alien fish are constantly emerging in the ocean.

Is humanity really going to be destroyed? Helpless?

Wang Han didn't think about this problem, he had already killed the red eye, and when the bullets ran out, he would change to hand-to-hand combat. These squeaky little green-skinned monsters in front of him, who were innocent and cute children two hours ago, have now become enemies, although weak, they are extremely aggressive, and their arms have evolved bone spikes comparable to tungsten steel, which are specially evolved against the exoskeleton defense system of human soldiers, as long as they cut through the flesh and skin of humans, they can transform humans into their kind.

The monster with black pigtails on her head, her name was Yang Ziyan two hours ago, and she used colored pens to draw a crooked five-pointed star on Wang Han's hologram mask.

Wang Han thought at that time that he would simply consider her as his goddaughter, and he would have a descendant. But now, Wang Han could only stick his left hand around her neck and stab her three inches under her lower abdomen with a chopping knife - she had eaten too many corpses of the same kind, and the rest of her body had evolved into invulnerability, and only this was her weakness.

When the battle was over, the medic went up to spray the disinfectant, and Wang Han hid in the toilet to smoke - in fact, he didn't want the soldiers to see the tears on his face.

Before he finished his cigarette, the commissar came over and said, "Seven hundred and twenty-four in total." ”

Seven hundred and twenty-four refers to seven hundred and twenty-four children, before Wang Han received the order to protect Yuying Primary School, six adult worms had already broken into the school sewer, and the children were poisoned if they didn't pay attention for a while.

The commissar was also aggrieved, but he didn't say anything, every soldier here was aggrieved, and humanity all over the world was aggrieved, but what could be done?

At five o'clock in the afternoon, an anti-gravity black Wuling commercial vehicle came, which is rare in the front-line battlefield, and the anti-gravity technology was successfully developed only two months ago.

The door opened, and a beautiful woman in a skirt uniform came down, and all the soldiers were stunned.

Not because she was beautiful, but because she had long legs, was smooth and slippery, and didn't even wear stockings - such a dress appeared on the front line, which was undoubtedly self-defeating, so that most of the soldiers could not resist aiming their guns at her to prevent her from suddenly mutating.

Wang Han was angry at that time, "Why are you so brain-dead? Don't pick a good time to die? ”

The female soldier didn't speak, but just dusted her shoulder, as if there was ash on the two golden stars.

Wang Han immediately stood up and saluted, "Report to the chief, Wang Han, the head of the Second Iron and Steel Regiment, reports to you." ”

Although the action was done, Wang Han was thinking in his heart: This woman became a lieutenant general in her thirties, and her work must be good.

"You are wrong, I can be promoted to lieutenant general, not because of a good job, but because of my profession." The female lieutenant general in front of her said, neither humble nor arrogant, "My name is Liu Qing, a senior engineer of quantum physics research and development at the Damo Academy, you can call me Liu Gong." ”

it! Can this thing read people's hearts? Wang Han didn't dare to think about it anymore, but he still couldn't help but make a mistake: "Quantum physics? Are you here to help me adjust my neural connector? I always feel like the bones in my left leg are a little sluggish. ”

Wang Han said, his left leg stepped forward, and his lower abdomen was straightened forward, so that a large piece of his crotch bone bulged high, facing Liu Qing, so the intention was self-evident.

The surrounding soldiers were snickering, and Liu Gong was obviously aware of this, but she didn't care, continued to look at the test object in front of her, and said softly: "Wang Han, high Chinese, type B blood, Scorpio, height 185, weight 170, enlisted in the army on September 15, 2017, joined the Steel Legion in March 2025, and was promoted to regiment commander in July." In two months, your legion has participated in 15 large-scale interbridades, 32 medium-scale interdictions, and 165 skirmishes, killing a total of 325,000 xenomorphs, right? ”

Wang Han was stunned, looked at the person in front of him again, and replied blankly: "I haven't counted." ”

Liu Qing smiled, "Do you want to win this war?" ”

"Think, how could you not want to."

"Come with me if you want."

"Where to go? What about my team? Do you have an appointment from your superiors? ”

Wang Han asked a series of questions, but in exchange for the indifferent face of the beautiful woman.

"If you want to win, don't ask so much."

……

……

On Wuling Business, Wang Han couldn't wait to put down the flat seat, he needed a good sleep too much, the deep kind.

The state of not wearing an exoskeleton armor is simply cool.

But Liu Qing didn't intend to let him sleep, and continued to ask in his ear: "Do you know why I came to you in person?" ”

"Because I'm more handsome?"

Liu Qingwaner, "Sort of." As he spoke, Liu Qing brushed his hair behind his ears with his hand, and his movements were slightly charming.

Wang Han saw it, hurriedly turned sideways, an old man in his thirties, who hadn't seen a woman for several months, inadvertently had a physiological reaction. He had to cover it up.

Liu Qing smiled, "I came to you in person because this experiment is special, and I have to personally assess you." ”

Wang Han didn't understand, "What experiment?" ”

Liu Qing made a long story short: "IMHO, with our current technology, this war is lost, even if the enemy does not attack, as the corruption of the world accelerates, at most, the human race will perish." ”

They have the ability to destroy the earth, but they don't do that, they just continue to corrupt nature and assimilate the creatures on the earth, and it won't be long before the blue planet disappears and our world will become theirs.

This is a battle to exterminate the race, and there is no peace.

Wang Han didn't understand, "You just said you could win?" ”

"There is only one way to win."

"What's the solution?"

"We can't beat them because our technological development is too slow, if we give the earth another two hundred years to develop, they will no longer be our opponents, and when the time comes, it will not be them who will transform us, but we will transform them."

"You just said a month at most."

"That's right, so we're going to find a way to buy time." Liu Qing paused, let Wang Han cheer up, and listened carefully, "Do you understand quantum physics?" ”

Wang Han rubbed his face, "I don't understand." ”

"Well, I'll put it simply, at the moment we've built a teleportation device that can radio sheep from Beijing to Washington, but that's pointless, it's just a quantized cellular recombination, and the sheep before and after the teleportation are two sheep, even though they look exactly the same."

"What do you mean?"

"Consciousness thinking, sheep are animals, so there is not much difference, if you change to a human, from Beijing to Washington, the person is still the same person, but the consciousness will be lost, and the person who teleported to the past will become an idiot."

"! Where did the conscious mind go? ”

"That's exactly what I'm working on." Liu Qing said, "When the human body is reorganized, the brain is no longer the brain it used to be, and people's consciousness and thinking will disappear with it, and biologically speaking, people will die." ”

"Consciousness is the soul of man." Liu Qing focuses on pronunciation.

"And then? What are you looking for me for? ”

"Do you know gravitational waves?"

"I've heard that you use gravitational waves to observe four-dimensional space?" Speaking of this, Wang Han reacted quickly and got up from his seat, "I understand, do you want to teleport to two hundred years ago through the four-dimensional space to buy time for the development of science and technology for the earth?" ”

"You're really smart, just a little bit."

"What does that have to do with me?"

"This experiment is just an assumption, we are not sure that it will be successful, we need someone to do the experiment." Liu Qing looked at Wang Han with a sincere attitude, "As I said earlier, quantum teleportation will lose consciousness and people will die, this is still in the same world and the same time and space." And back to the past, it is across time and space, not to mention whether consciousness will disappear, quantum transmission requires two mutually interacting base stations, and the previous time and space of the earth have been in the era of cold weapons, and there are no base stations at all. ”

"So what?"

"We're going to project the human mind onto it, just like the exoskeleton suit you're using."

Wang Han can understand this meaning, the exoskeleton combat suit should be connected with the nerves of the soldier, and the brain should be used to directly control the external body movements to fight, which is equivalent to the soldier giving the combat uniform a soul.

"The Damo Academy has solved the problem of human immortality, and yesterday the thoughts of wounded soldiers were uploaded to the computer host and downloaded into combat robots."

"Cow Pi!" Wang Han gave a thumbs up, "So you're looking for me?" ”

"Regarding how human beings can save themselves, the Damo Academy has given three plans, one is to upload the thoughts of human scientists to the computer, and then launch them with rockets to find a new world. The second is to put human thinking into the body of the robot and go underground for development. The third plan I proposed was to send people to ancient times to accelerate the development of the earth's scientific and technological civilization, and to win hundreds of years of development time for the earth, so as to defeat them on the frontal battlefield. ”

Wang Han was stunned.

Launch rockets, which are easy to shoot down.

Going underground, without air and sun, how long can humans live?

It's best to go to ancient times, develop the industrial revolution hundreds of years in advance, and mankind will enter modernization early, and you are afraid that they will come?

"However, there is a problem, teleporting to ancient times, there is only a theory, and there is no experiment."

Wang Han understood, this is to let him be a guinea pig.

Liu Qing said: "We can now use gravitational waves to create space-time intersections, and we can see as far as the Northern Song and Southern Song dynasties, when the social structure had already sprouted capitalism, and as long as it was pushed a little, it would turn into an industrial society, which could usher in thousands of years of development opportunities for mankind." ”

Wang Han nodded, "Go on." ”

"This is the best solution and the least successful, if it succeeds, humanity will be saved, and the planet will be saved. So, we have to send an all-round talent over. ”

Wang Han squinted, "I think it's more appropriate to send a scientist over." ”

Liu Qing nodded, "As long as you agree, you are a scientist." ”

"What do you mean?"

"I'll stuff something in your head, about industrial development."

"If you have this technology, why did you choose me? It's okay to stuff something in someone else's head. ”

"Character is more important, scientists are smart, but they are not necessarily suitable for that era, what is important is character. We want heroes, not nerds. ”

Wang Han understood, lay back in the chair, looked at the roof of the car, "Let me think about it." ”

"Don't think about it, I know what you want, as long as you agree, I will be satisfied with whatever you want."

Wang Han sat up again, stunned for a long time.

Liu Qing laughed again, but it was a bitter smile, "If the experiment fails, you will become an idiot, if the experiment is successful, do you know what it means?" ”

"When you succeed in that plane, the space-time of this dimension will collapse in an instant, and everything will disappear, including those alien ships in Earth's orbit."

"What about you?"

"It will also disappear, but in another time dimension, a new space-time node, maybe there is me, maybe not, but the alien spaceship must have, maybe it has been wiped out by humans in outer space, who knows."

Wang Han was silent, as far as the current environment was concerned, he didn't have much choice, even if he didn't die on the experimental bench, he would die on the battlefield, sooner or later.

He agreed, but still said his wish, "Liu Gong, it's okay for me to be a guinea pig, but I don't want to die with regrets, you see, I'm still a virgin." ”

Liu Qing smiled, pressed the privacy button, and the curtains of the commercial vehicle moved slowly and closed automatically.

"Wait, Liu Gong, I'm a little nervous." Wang Han said shyly: "I still don't understand, why do you have to find me and say a good assessment?" ”

"Don't be nervous, this is the assessment, you will understand later."

……

……

Three days later, at the headquarters of the Hangzhou Damo Academy, the Quantum Physics Laboratory, hundreds of scientific researchers were waiting for them, and with the formation of the four-dimensional space, countless ancients appeared above the laboratory out of thin air, like a mirage. They come and go, talk and laugh, but on the screen of the researchers, there are strings of characters.

They want to find the person who is most compatible with Wang Han's brain waves, and at the same time, the development potential of this person's body structure must be the best, this is the first time in human history, if it fails, there will be a second time, if it succeeds, this will be the only time.

The next time I travel through, it will be the technology of another time and space.

Finally, they locked on their target, it was a thirteen-year-old boy, slender and weak, but his brain waves and Wang Han's brain waves were perfectly matched, and his body structure genes had great potential.

Liu Qing immediately ordered, "It's him, execute!" ”

With the order, a strong tingling sensation entered Wang Han's brain, and he didn't even have a chance to cry out for pain, he felt that the surroundings suddenly turned black, as if a whirlpool was dragging him down, falling faster and faster, but bottomless.
