Han Wu is a genetically modified person, ranked No. 5 In the laboratory. Perhaps it is because it was winter when he survived from the laboratory. He has never seen the outside world once since he was growing up in the laboratory. Wearing a thin laboratory coat, he experienced the bone-chilling cold of winter for the first time. He is homophonic for Han. He was taken in by an illegal organization for genetic modification since he was a child. A group of more than 200 children were trained and experimented together since childhood. The last experiment was a head nano-superbrain inlay experiment. Han Wu was the first to do the experiment. Don't ask why No. 5 Was the first to do it. That was because No. 1 To No. 4 Were all dead. The international peace organization broke into the laboratory and activated the self-destruct program, killing everyone. Why did Han Wu survive? Because the core control computer of the laboratory has independent consciousness, it is stored on Han Wu's nano super brain in order to survive, and then activates the laboratory's core technology carbon-based nanorobots. Up to 1 billion nanorobots forcibly merge and symbiosis with Han Wu. Fortunately, Han Wu is a genetically modified person, otherwise ordinary people would have died of bleeding and explosion.
