In Xingyuan 2217, an explosion occurred in the life science laboratory outside Teito University, and an unknown energy body leaked. None of the 23 researchers in the laboratory and the main person in charge of the laboratory, Professor Zeng Jingren, survived.
After the unknown gas released by the explosion was inhaled by the human body, some people had a mutated reaction. The blood of the mutated people would turn blue and they also had some kind of superpower, so they were called people with different blood.
The emergence of people with different blood broke the original order and balance of the empire. At the same time, there were frequent cases of people with different blood abusing their powers in the empire, causing a very chaotic situation. The people complained, and people with different blood became a hidden danger to the empire. Under pressure, the High Court decided to establish the Alien Agency, responsible for the work of dealing with and researching people with different blood.
The consequences of a failed experiment were not only a nearly destructive explosion, but also a conspiracy change. The young man who once yearned for a peaceful life encountered an accident and mutated into a different-blooded person. Bai Jian's life has undergone earth-shaking changes since then. Every tomorrow is the "doomsday" for him. Before the advent of the different-blooded people, what is the future? Where again? There is no way to know the answer. And the source of all this is because of the person who should not have appeared in his life.
