In the second year of the reign of Emperor Kangxi of the Qing Dynasty, the chief instructor of the Eight Banners, Kaohsiung (played by Kaohsiung), violated the law of intermarriage between the Manchus and the Han people, and was intercepted and killed by the Bat Master (played by Yuan Xinyi) ordered by Prince Su. At the critical moment, Kaohsiung kidnapped Prince Su's little Beile and fled, but he accidentally strangled the little Beile to death... Fourteen years later, there are brothers and sisters "Qimen" (played by Liang Jiaren) and "Dunjia" (played by Yuan Xiangren) in the Jianghu with powerful magic. Although they are eccentric, they benefit the people from time to time. In the town where Qimen Dunjia lives, there is Kaohsiung who has been hiding his name for many years. Kaohsiung picked up an orphan "Shugen" (played by Yuan Richu) and raised him with all his heart. Soon Kaohsiung's identity was exposed, and the Bat Master chased him again, and planned to disguise Shugen as the missing little Beile in the past so that he could control the court. Kaohsiung died in a battle with the Bat Master, and Shugen had to ask Qimen Dunjia for help, which triggered a series of incredible magic duels...
