The Reborn Big Shot Returns for Revenge [Apocalypse]

In the human apocalypse, the survival of the species faces a crisis, and humanity stands on the brink of extinction. Scientists launch a cruel single-subject reproduction experiment, and Xing Yi is forced to become one of its test subjects. Later, the experiment fails, and every test subject dies. Years later, Xing Yi returns, reborn as a mutant created by the experiment. He has come for revenge. But a little wolf pup has set its sights on him. A cocky, flamboyant, devilishly charming top who thinks he's the best in the world vs. a seemingly silly, honest, and obedient bottom who is actually a master of disguise P.S.: 1. No pregnancy. This is not rebirth in the traditional sense. 2. Setting: The human apocalypse, with people living in an artificial Eden base. 3. All theories in the story are the author's invention and have no scientific basis. Theme: Humanity will overcome every obstacle in the end!
