Lin Bei is the president of the Lin Group and an experienced angler. During a fishing trip, he is killed by his wife, Xu Weiwei, and her male best friend, Zhou Teng, a manipulative playboy, and sinks to the bottom of a lake, where he transforms into a fish and awakens the Shocking Evolution System. By shocking others, he can earn evolution points and evolve himself. To quickly obtain Lin Bei's inheritance, Xu Weiwei and Zhou Teng launch a series of schemes, but Lin Bei's parents hold them back with their insistence that "they must see him alive if he's alive, and see his body if he's dead." Resentful, Zhou Teng plots to kill Lin Bei's parents. When Lin Bei accidentally learns of this plan, he begins fighting for survival to thwart his wife's and her male best friend's schemes and protect his parents.
