In the most inconspicuous "Destiny Pawnshop" in Yunzhou City, the shopkeeper Su Mo appears to be a cynical salty fish, but in fact he is a "Destiny Trader" responsible for the system. A fragment of the Book of Life and Death hangs around his waist, and the fate of the monks in the world is held in his palm. However, he is forced to accept a disciple due to a mandatory task in the system. The first disciple is actually Chu Zhao, who is responsible for the blood feud of the family. The fate-defying sword and the black dragon bloodline in his body are the key to the massacre of the Chu family ten years ago.
When the copper coin abacus turns into a gossip array, when the roasted chicken stall hides a portal to the demon world, Su Mo leads his weird apprentices (the cook Lin Xiaowan who can talk to animals, the young God of Wealth Qian Manguan who uses the abacus to deduce heavenly secrets, and the bookworm Bai Jingxing who secretly learns forbidden arts) while doing weird things in their daily life while getting involved in the power struggle of Yunzhou College, the secrets of the Palace of Life and Death, and the Zhongzhou sect game.
As the fragments of the Book of Life and Death appear one by one, Su Mo's mysterious identity (the successor of the master of the Palace of Life and Death in his previous life) and the hidden physiques of his disciples (Chu Zhao is actually one of the chosen ones) are exposed one after another. The mastermind behind the scenes is the resurrection plan of the ancestor of the Yun family, pushing everyone to the ultimate choice of "changing their fate against the will of heaven" - should they comply with destiny and become pawns, or tear up the script and rewrite the rules? A fantasy adventure with a smile and a knife begins here!
