Xie Kening died once when he was seven years old. Although he was later revived, he had no memory of before he was seven years old. Since then, he has developed spiritual vision and can see people's energy fields. He has also been troubled by the ability to see spiritual bodies. He doesn't know his own life experience, and he doesn't know that he has the heart of a monster.
Li Weiwei has been looking for Xie Keying, not because of his evil intentions, nor because of the fate of the witch hunting group and the wizard, but just to repay Xie Keying's kindness in his previous life, and to protect him no matter what in this life. They were husband and wife in their previous life.
