Du Xiaoxian was mistakenly thought by the Qingyun Sect to have no spiritual roots but sneaked into the outer sect, relying on wit and mischief to survive everywhere. From accidentally falling into a small scam in the fairy sect, catching fairy beasts, to falling into the sect hegemony and the catastrophe of the six realms, with humor and cleverness, he saved the day and got acquainted with people (Peng Pangpang), immortals (Ye Qianqian), and beasts (Yun Xiaoliu). He grew up step by step in the battle between the masters, the secret of cultivating immortals, and the changes in the immortal world, and finally defeated Shangguan Wuyou, a master of strategy, with an ingenious strategy. Not only did he protect the sect, he also saved the six realms and became the "Laughing Immortal" who counterattacked.
