Li Duduo, an ordinary social worker, dreamed one night that his deceased grandfather was crying about poverty and claimed that he was about to become a beggar in the underworld due to "inflation". Grandpa proposes "trading across time and space": his grandson burns paper money in the underworld, and grandpa exchanges it for "mana" in the underworld, and remotely assists his grandson in making money - the more he burns, the stronger the mana becomes! From then on, Li Duoduo embarked on the road of "burning money to become stronger", relying on his grandfather's underworld powers to get rich and slap him in the face, but he gradually became involved in the dual disputes between the underworld and the underworld.
