Lu Shaoyou, a hot-blooded and funny young man who runs a street stall, activated the fishing system by "casually fishing" by the night market river. From then on, he fished out lost secrets of ancient martial arts, black cards in the world, and even "funny props" that can resolve crises. He originally wanted to sell sausages safely, but he was involved in the bloody turmoil of the urban underground world, but he always used outrageous tricks to turn the killings into hilarious scenes. In order to protect Su Qingqing, the daughter of a wealthy tycoon with an extraordinary appearance, whom he accidentally met, Lu Shaoyou grew up from the "God of War" to the "deadslide" that caused headaches for both black and white. While using the strange moves fished out by the system to defeat the enemy, he used his words to resolve grievances, and finally revealed the secrets of the underground world for twenty years, leading Su Qingqing and a group of "brothers he had cheated" to a passionate and heartwarming ending.
