The play is adapted from Teng Ping's novel "Auspicious Lotus Tower". Ten years ago, Li Xiangyi, the leader of the Si Gu Men, was the best in the world with the Xiangyi Tai Sword and was the light of the righteous martial arts world. However, because he had a battle with Di Feisheng, the leader of the Jin Yuan League, in the East China Sea, the two masters disappeared on the vast blue waves. The Si Gu Men and the Jin Yuan League were both defeated and gradually disappeared from the world. Ten years later, Li Lianhua, a rural itinerant doctor, dragged a lotus tower to the world and accidentally got the title of a famous doctor. He didn't want to get involved in the world of martial arts, so he was involved in the world of martial arts. Fang Duobing, a passionate young master who dreams of being a hero and bringing peace to the world, realizes that Li Lianhua is not simple, so he vows to find evidence of Li Lianhua's impersonation of a famous doctor. Di Feisheng, who has always regarded Li Xiangyi as a strong enemy, recognizes the humble itinerant doctor Li Lianhua as Li Xiangyi after returning to the world of martial arts. How can he let him go easily? After a series of cases, the three of them actually forged a deep friendship in the process of solving the case with laughter and anger. Li Lianhua and Di Feisheng, who had originally lost interest in martial arts, were inspired by Fang Duobing, a young man who took the safety of the people in the world as his own responsibility and rekindled their passion. The three of them joined hands to fight and solve strange cases in the martial arts world, and to restore justice and peace to the world.
