In 1128, Luo Cong, the first Taoist priest in the Three Realms, passed away at the age of 178. When he was alive, he worked hard to eliminate disasters in the world. He should have seen through everything in the world, but in his later years he encountered the biggest doubt in his life, which almost negated everything he had done for the world in his life. He, the strongest man in the three realms, has done so many earth-shattering things in his life, but in the end it was all in vain? He regarded this temptation as his biggest enemy, and it gave rise to the first and last fear in his life. Before he died, he thought of a "person" who could answer his questions, but this "person" told him to tell him the answer the next time they met. For this reason, he coerced the underworld to allow him to reincarnate indefinitely until he achieved his long-cherished wish. After 37 reincarnations to no avail, a turning point finally came on the 38th time. This time it was not a human being, but a stuffed toy beside a girl. The most powerful toy in the three worlds wants to escape from the girl, but is attracted by her bizarre physique. Luo Cong, who is dedicated to solving puzzles, has to go through many tests, but this girl "happens" to be the key to solving the problem...
