The story begins with Pei Rong's bizarre farce: he accidentally disrupted a grand event and was involved in the dispute between the fairy world and the devil. Various sects and forces of good and evil appear in turn, and the traditional standards of good and evil are constantly subverted by the protagonist and companions through absurd plots, revealing the hypocrisy and complexity of human nature. Along the way, Pei Ku formed intricate friendships and loves with Ji Xizhi, Jing Wumian, Li Xiaochan and others, and constantly tested his own bottom line. After experiencing factional disputes, family feuds and power struggles, and fateful decisions - behind every laughter and absurdity, he finally moves towards self-independence and understands the true meaning of "immortality": not immortality, but inner self-consistency and peace of mind. The book has a compact structure and many story lines. It makes good use of humor and irony, and echoes each other. Major events promote the growth of the characters' mentality, and the ending is smooth.
