During the war between gods and demons, the demons spread the demonic energy they cultivated into the mortal world, and the demonic energy enhanced the desires and sins in people's hearts.
After the war stabilized, the Emperor God divided the mortal world into two worlds. One world in which the evil-doing descendants lived, and another world outside where people who had not had time to reincarnate during the war lived.
The ancient snake demon Mo Ying and the ancient fox demon Yin Mei broke into the other world.
Qingyou, a member of the Qingqiu Divine Fox Clan, was reincarnated as Liyou to eliminate demons, and Bai Wuyou assisted him.
Mo Ying and Yin Mei captured a simple, kind, gentle and honest person and used them as a weapon to kill people.
