With the end of the Fourth World War, the world has entered an unprecedented nuclear winter, and the Ice Age has arrived, and the ground has long been unsuitable for human habitation, and it can even be said that the land is not a territory that humans can set foot in.

The fourth world war with the continuous advancement of the war, countries are also completely red-eyed, the countries with nuclear weapons in the later stage of the war even used nuclear weapons, as for the countries without nuclear weapons are under this nuclear peace turned into ashes, but this is not the most terrible, the most terrible is that under the outbreak of nuclear weapons war, the biological and chemical weapons that will be carried out in the secret will also be leaked to the world after the nuclear weapons play a role, the radiation of nuclear weapons and the sensitivity of biological and chemical weapons to the atmosphere, Most of the creatures on the ground died in just one day, and if it weren't for the fact that a small number of creatures took refuge in the shelters that had been built since the Third World War in 3000, it is estimated that this time would have been the day of the end of humanity.

However, as time passed, humanity, which had survived the Fourth World War, did not know that a darker conspiracy had once again loomed over them......

After a hundred years, with the powerful and perfect function of the shelter, human beings have been alleviated, and it can even be said that there has been some development, of course, this is only the development of science and technology, and the population cannot be recovered so quickly, after all, the total population of the world before the Fourth World War has been 13 billion, and the survivors are only 200 million.

In a hundred years, human beings have not given up the hope of returning to the ground again, so the development of science and technology today is some preparations for the return to the ground - consciousness bridging, which is to bridge the consciousness of human beings to the body of the robot, and then put the robot on the ground in the nuclear winter, and use the body of the robot to explore the ground for human beings, so as to prepare for the return of human beings to the ground.

In the past 100 years, the human beings who survived the world war have completely settled in the shelter, and the panic and anxiety when they entered the shelter to escape the war are long gone.

In the midst of this bustling flow of people, there were two young people who seemed a little out of place with the crowd around them.

"Hurry up, our mech! The kids are still waiting for your explanation! ”

A young girl with a delicate face is playfully pulling a teenager, and the teenager is being pulled forward helplessly.

"I said, Shaoxue, I'm just becoming a mechanical envoy, what do you want me to say to the children in the welfare home?"

That's right, it's a welfare house.,It's a welfare house in an underground shelter.,But it's also a measure by the high-level of the shelter to appease the family of the dead mechanical envoy.,Teenagers and girls also grew up in the shelter.。

"Shaohua, how could you not know what to say, don't think that I don't know that you have already gone through a mission, don't think that if I am a medical worker, I don't know what is going on with your mechanical envoy. If you don't make those little brats happy this time, I'll want you to look good!"

Shao Xue's little fist shook in front of Shao Hua's eyes, in order to blackmail Shao Hua, but it was obvious that Shao Hua really ate this set.

"Hmph, good men don't fight women!"

After Shaohua said this, he directly broke free of the girl's hand and ran away, and the girl also reacted in an instant and immediately chased after her.

"Shaohua, how dare you run? Stop!"

"Slightly, if you don't run, isn't that a bad pen? Do you think I am? Bye-bye, crybaby!"

"Ahhh You'd better not let me catch you, or I'll want you to know what life is better than death!"

The two chased each other on the path to the shelter, but the people around them didn't mean to stop them, and it was clear that they were used to this scene.

"It's good to be young, I really envy the energy of the two of them."

"It's a good thing to have energy, I'm afraid I don't have energy, but I really didn't expect that kid from Shaohua to become a mechanical envoy, this time the fish jumped into the dragon gate."

"What you're saying is yes, who doesn't want to be a mechanical envoy now, but it's a pity that our consciousness doesn't fit the link terminal of the mechanical body at all, and we only have envy!"

"I'd love to see the ground, and the sun mentioned in the book, but it's not the time yet, I really hope those mechanics can speed up the exploration of the ground."

After saying that, he looked up and saw the lights above him that were emitting dazzling light, but no matter how bright it was, it was still not the real sun.

"If we were mechanical envoys, we would be able to see this, what a pity, forget about it, let's finish today's work quickly."

"Alas~"

A sigh directly interrupted the conversation between the two, and they began to bury their heads in the road, but the desire of the two was not the desire of the people around them. But all this may be fate, they can't become mechanical emissaries after all, they can't set foot on the ground, all of this is what they know from the notice of the shelter, without the protection of the conscious machine, they can't survive on the ground in the nuclear winter.

In a hundred years, most of the previous generation has passed away, and the new generation has hardly really seen the ground and the sky, they can only understand all this from projections or books, they are like newborn children who want to understand the world and want to see the ground and the sky in person, but the reality does not allow them to do this, because now only the mechanical envoys can go to the ground, and the conscious mechanical body completely isolates nuclear radiation and biochemical gases from the body. And forcibly convert the external gas into the oxygen needed by human beings, which is also one of the reasons why the machine can step on the ground, as for the other reasons, it is natural to have various crises on the ground, don't think that there is only nuclear winter and biochemical viruses on the ground, natural selection still exists after all, in a hundred years, there will always be biological evolution, it is more consistent to say that it is mutation, after all, the double invasion of nuclear winter and biochemical viruses, even the evolution of species will not be able to survive in this environment. Then these mutated species are the biggest threat in addition to nuclear winter and biochemical viruses, if humans want to set foot on the ground again, these mutated species will be a big resistance, in addition to exploring the ground, the mechanical envoy is to eliminate these resistances one by one, for this reason the consciousness of the mechanical envoy is the most powerful weapon of human beings today, a new weapon with the attribute of self-evolution, of course, how these weapons were obtained is a mystery, of course, this mystery is only for ordinary people......
