The male protagonist, Lin Bei, is the president of Lin Group and also a seasoned fishing enthusiast. During a fishing trip, he was killed by his wife, Xu Weiwei, and her green tea male best friend, Zhou Teng, and thrown into the lake, where he transformed into a fish and awakened the Shocking Evolution System, which allows him to gain evolution points and evolve himself through shock. Xu Weiwei and Zhou Teng launched a series of activities to quickly obtain Lin Bei's inheritance, but were constrained by Lin's parents, who demanded to see him alive or his body if dead. Zhou Teng harbored resentment and wanted to kill Lin's parents. After Lin Bei accidentally learned of this news, he began to strive for survival in order to expose his wife and male best friend's schemes and protect his parents.
