The grassroots young man Jin Xiaochuan and the rich second-generation Chu Ersi accidentally broke into the ninth floor of the Demon Gate and accidentally got involved in a hundred-day purge between the government and the famous sect. There is a mysterious jujube tree hidden in Jin Xiaochuan's Dantian, which can absorb spiritual power and toxins; Chu Twenty-four can improve his strength by eating dry food. Relying on their strange abilities, the two made fun of each other while fighting monsters and hoarding resources in the Ziyang Mountains. They met strong people from all walks of life, solved the crisis of ferocious beasts, and killed their pursuers. In the end, they learned the inheritance of the orthodox demon sect, carried forward the Nine Floors, and Chu Twenty-four was one step closer to leaving the brothel dream.
