For five hundred years, the demon saint Qi Tian fought against many generals of the gods in the heaven! Before he died, he used the forbidden dissociation technique, exploded and destroyed the Nantianmen, and his soul was scattered in the three realms. Five hundred years later, Lu Xiaotian, an intern soul master of the Tianshi Academy and a sweeping boy, accidentally opened the portal to the demon world, and also started a huge plan for the three realms to resurrect the demon saint. However, as the main soul of the demon saint, Lu Xiaotian needs to merge with other people who have the souls of the demon saints in order to resurrect Qi Tian. For this reason, he fought with the gods and demons. It was obviously a life-and-death adventure that shook the world, but Lu Xiaotian always made him laugh and cry~ But it was this sand sculpture boy's spirit, pure and brave, that was expected to untie the knot of the three realms cycle and give freedom to the people! Until the souls dissociate and unite! The demon saint returns! Resurrect and fight again!
