Gu Junyu, an "ordinary" scientist.
He was originally a "genius" scientist who devoted himself to scientific research. Before the end of the world, he was hailed as "the brightest new star in the scientific world." However, after the end of the world, he is indeed a "mad scientist" who has destroyed humanity.
Maybe there really is only a thin line between genius and madness.
He dragged the whole world with him into annihilation.
When he opened his eyes, he found that he had become a ball of energy-like light. In other words, this ball of light suddenly had a memory, a memory that could not be said to be from the past or present life.
Intention: To cause trouble? How can I enjoy doing scientific research?
