Li Xiaoman, a "martial arts loser" in Qingfeng Town, accidentally picked up a book called "The Magic of Luck" in the cellar next to the pig pen. This prank book was written by a gangster, which allowed him to run wild in the world with a lot of luck. On the way to follow Zui Lao Tao in the world, he not only has to deal with the provocation of Murong Villa, the pressure of Taishan Sect, but also needs to avoid the Nether Sect's coveting of magical powers. When luck becomes the most powerful martial arts, can this man who loves steamed buns rely on his "lying to win" physique to unlock the secrets of magical skills and counterattack to become a true martial arts legend?
