Lin Doudou, a mortal boy with mediocre qualifications but a big imagination, accidentally entered the world of cultivation. At the beginning, he encountered obstacles everywhere. By chance, he met Gu Ranran, Fat Taoist and other partners along the way, and continued to counterattack and grow in various sect competitions, adventures in secret realms, and conspiracies. Doudou relies on optimism, humor and perseverance to solve problems, transforming from a despised little handyman to the hope of the sect, and step by step uncovering the shocking shady behind the world of cultivation. In the struggle between good and evil, loyalty and intrigue, Doudou used his own way to influence the people around him, and finally broke through the boundaries, leading relatives and friends to fight against the demonic realm, turning conflicts into friendship, and writing a legend unique to the "unorthodox" immortal cultivators.
