As the new King of the South Hell, Nan Suan has always maintained close contact with the Yu Clan, a family of soul-chasing people in the human world, and is responsible for cleaning up the Soul-Eating Clan in the human world. Originally, this kind of cooperation maintained the peace of the two worlds. However, since Yu Xinxin's father died unexpectedly five years ago, the number of abnormal deaths in the Southern District has increased rapidly in the past five years. But Nan Suan couldn't find any other soul chasers or families to take his place, so he had to find a way to deal with the Soul Eaters in the human world and the underworld. The lost Yang Shou Lu contains Yu Xinxin of the Yu clan of the Zhuiling clan and most of the elders of the Yu clan, including Yu Xinxin's father, Yu Heng. Although Nan Suan is the King of Hell in the Southern District, he is responsible for managing large and small matters in the Southern District. But he himself doesn't like to take care of things. Since he broke off with the Yu clan, the Southern District has been called a place of difficulty. All kinds of strange things happen every day, and every thing involves the terrible conspiracy of the alien race behind it.
Purpose: To explore the world after human death. Is it no different from living?
