Creator's Endgame

An asteroid carrying a huge amount of radioactivity and with no time to change its trajectory collided with the earth. It hit the active volcanoes and spewed out a large amount of magma. The earth also entered a period of resource depletion. The land covered by magma and barren of grass at that time, due to radioactive materials, formed creatures that were similar but different from the original ones. More than a hundred years later, scientists and construction workers who were forced to explore this land built a new city here. One of them discovered an underground world with excess energy. Hundreds of years later, a young man from the underground who was nicknamed the "Prince of Desolation" frequently went to the surface to look for people who could completely "defend" against radioactive energy, and found the "ordinary young man" Mo Shiyi. He called Mo Shiyi "the only bargaining chip" in order to fight against his invincible relative. Two male protagonists, no love story.
