A millennium after the Conferred Gods War, the world is at peace. The Saint of the Intercepting Religion remains secluded in his Biyou Palace. The ancient Buddha, Ran Deng, has yet to pass away; the Buddha Sakyamuni has yet to be born; and the Western Pure Land has yet to be created. Ba Jie is still the celestial general Tian Peng, the Monkey King is still a stone monkey, the Ruyi Jingu Bang is still the Dinghai Divine Needle, and even Jin Chanzi is just a golden cicada. However, the leader of the Intercepting Religion, Tong Tian, has secretly begun a wondrous journey, exchanging bodies daily with Xu Ji, a convenience store owner from the modern world. Thus, modern society gains a Primordial Saint, while the Three Realms of the prehistoric world gain a clueless mortal with a saint's body and countless innate spiritual treasures.
