Modern young man Zhang Fan traveled to the world of "The King of Firepower". He thought he could dominate the competition with his foresight and hard training, but he was hit by reality. In desperation, he tried to apply the theory in the "Five Years of Immortality and Three Years of Simulation" that he accidentally obtained in his previous life to the yo-yo, and accidentally created the "Lingyou" school. As he and the protagonist group Li Fei and others deepened, they discovered that the power of yo-yo was far more than that, and an ancient world of cultivation hidden under the appearance of competition was gradually unveiled. They must deal with increasingly stronger opponents on the field while resisting mysterious threats from other worlds to protect the balance of the two worlds.
