After the war, the resource-scarce Earth entered an era of humans raising aliens. Lin Yi, an 18-year-old animal man, discovered on his adult day that his parents were actually cannibal aliens and awakened his "death retrospection" ability. He teamed up with Zhou Kai, Zhou Yun and others who had also awakened their powers to form a team and escaped from the city occupied by aliens. On the way, he was chased by various monsters such as tentacle mantises and snails, and met partners such as An Chengdao and Zhang Cheng. Along the way, everyone uncovers the truth about the "Human Pasture", fights against the forces of Strel and the ultimate alien illusion, and explores the hope of freedom and human survival in the counterattack of life and death.
