Liu Xiaoyao, who has mediocre talent, grew up in the Xiaoyao sect since he was a child. He made all the immortals laugh and summed up his unique skill of "self-defeating to resolve crises". After a sect competition, he discovered that he had the key ability to break the seal of the six realms. After being involved in the turmoil in the Six Realms, Liu Xiaoyao met Su Jinyao from Tianji Pavilion, martial arts master Feng Chen and the talking fox. The three people and one beast escaped from the chase and outsmarted the villain Mo Xiyan in the midst of amusement and danger, and gradually uncovered the truth about the chaos in the six realms: the centuries-old grudges between the immortal and demon realms, the mysterious ancient seal, and Liu Xiaoyao's own shocking life experience. After going through twists and turns, Liu Xiaoyao grew up to be a true immortal capable of taking on great responsibilities. Together with Su Jinyao, he guarded the Six Realms and wrote a legendary destiny with laughter and tears.
