Xiang Liu, the demon king of the Northern Kingdom who was punished by Dayu, came back again. Nuwa moved to the head of the Nanshan Mountain after repairing the sky. She was really worried about the people of the Northern Kingdom, but she knew that a direct fight between the gods would bring great pain to the people. According to the divination of the astrologer around Nuwa, Chu Yi, a descendant of Nuwa, can definitely eliminate Xiang Liu's troubles, so Nuwa brought Chu Yi back to her era through the way of reincarnation. Xiang Liu decided to move to Dongshan after completely destroying the Northern Kingdom, so Nuwa sent Ba She, one of her guardian gods, to accompany Chu Yi to quell Xiang Liu's disaster. Ba She is aloof and arrogant. Although he is obedient to Nuwa, he does not agree with Chu Yi. Even so, the two of them still took steps to go to Dongshan.
