The seemingly wandering doctor Li Yunfei, the vengeful orphan Liu Ruyan, and the fat man "Qu Qu Qu" who pretends to be a pig and eats the tiger are tied together by fate because of an unjust case in the ghost market. From mutual distrust to tacit understanding, they successively solved three strange cases: salt gang smuggling, bodyguard bureau extermination, and brothel mystery. The clues finally pointed to the mysterious organization "Tianji Tower". The truth gradually emerged: Tianji Tower is actually controlled by the prince of the imperial court, aiming to achieve absolute control over the martial arts world by creating chaos in the world. The three people's own massacre was also part of their plan. In the end, they gathered the righteous forces of the world and defeated Tianji Tower's conspiracy to subvert the martial arts world in the final battle. They also each said goodbye to the past and hid in the world together to continue writing the legend of "Three Xians".
