In the ancient East, inside the frozen Everest, there is a completely different world from the outside world - Peach Blossom Spring. Because the Sun Sword in the cave absorbs the essence of the sun and the moon, the Peach Blossom Spring is impermeable to ice and snow, and it is spring all year round. In order to obtain the Sun Sword to dominate the three realms, the Ghost King killed a pair of immortals in Peach Blossom Spring. Momotaro, who escaped from the Ghost King's clutches by chance, was determined to eliminate the Ghost King with the help of the fairy to avenge his parents. After the Ghost King got the Sun Sword, he did all kinds of evil and harmed the world, so Momotaro and the folk ghost-fighting team led by Xiguataro joined forces to fight the Ghost King to the death.
