In the Tang Dynasty, Tang San practiced hard for three years and came down from Lingshan Mountain. He devoted himself to the Tang Dynasty to compete for the supremacy of martial arts. Begging all the way to a strange city, he had no idea that three years in Lingshan, thousands of years had passed in the outside world, and he had traveled to the 21st century. Various monsters led by the golden-winged roc are entrenched in the city, and Shituo City has become a monster nest. Tang San mistakenly fell into a trap and stepped into a gathering place of monsters. Faced with thousands of monsters surrounding him, Tang San was angered by saying "bald donkey" and directly killed the lizard monster with a punch. The war between humans and monsters broke out.
