Lu Hai, as a young disciple of the sect with mediocre qualifications and a thief, awakened the 'Laughing Spirit Root' by accidentally eating spiritual grass. He studied under the shady master Shu Xuansan, met his money-obsessed best friend Qian Duoduo, and the arrogant genius Su Ling'er, and made countless jokes in the world of cultivation along the way. Faced with the machinations, the prodigy of the demon sect Qin Bugui, and the mysterious girl Ji Yaoguang, Lu Hai relies on his wisdom and humor to avert dangers in sect battles, adventures in competitions, treasure hunts in secret realms, and catastrophes in the fairy world. He gradually grows up, deciphers the secrets of himself and the world, and finally laughs proudly at Xiuzhen Tianya in a relaxed and humorous way.
