Broken Glass Burning Shadow

A long time ago, a monster from the outer world invaded the human world. Humans called it an alien beast. The plot mainly focuses on the resumption of human civilization decades after the alien beasts were defeated. A small number of scientists accidentally discovered that after the genes of alien beasts and humans are fused, humans can master specific mysterious powers. The male protagonist Ling Yan is the 54th subject in the experiment that year. After the assassin organization reveals its secret, Ling Yan will inevitably participate in the massacre game planned by its scientists back then.
