The protagonist, Chen Linqi, is an ordinary high school student who broke up with his girlfriend and encountered some strange things one after another, and became the only "ordinary person" among the hybrid species. Along the way, he only relied on the help of the magic knife and his demonic side to find his former self and unravel the truth of the world. However, every time Chen Ling appeared, Chen Linqi's rationality was taken away. In the end, everyone around him left one by one. Chen Linqi could only climb the throne of the king of the eating beasts alone to end the devil's era dominated by the eating beasts.
