An ordinary person, at least in the eyes of humans, has traveled through loopholes in the laboratory countless times, constantly traveling between the past and the future, and trying to single-handedly change the doomsday of man-made destruction caused by the virus. However, the truth he found was the reason for his departure, and the causal relationship became a cycle for him. Maybe mutation brings not superpowers, but destruction. Maybe time travel does not allow you to point out the country, but to explore the truth. Maybe the virus is not a disease but a genetic modification program. Faced with self-righteous choices, human beings may only have a chosen future.
Concept: The powerlessness and insignificance of human beings in the face of nature
