Xu Sanyu, a veritable "salted fish" in the world of cultivation, thought he would wallow among mortals for the rest of his life, but he was accidentally involved in the farce of being selected for the Immortal Sect, embarking on a path of cultivating an immortal with ups and downs, surprises and dangers. He and a group of equally unreliable partners "fight monsters and level up" with enthusiasm and fun. They go through levels and make fun all the way. Friendship, love, and struggle take turns, and finally counterattack the immortal in the fairy world full of jokes. The suspense in the three volumes progresses layer by layer, from the growth of rookies, unity and defeat to the final battle, gradually revealing the secrets of the world of cultivation and one's true identity. The plot of the book is compact, with frequent laughs. It integrates passion, humor and warmth, subverting the traditional fairy tale routines and witnessing the legend of a group of small characters making a comeback against the odds.
