Spiritual cultivation and demonic cultivation are just a way of pursuing the Dao. In spiritual cultivation, there are people with human faces and animal hearts, and there are demons who have clear grievances.”
He became jealous but did not want to admit it, in the step by step fall, he found out that the person who died for him, his best friend, his first love, and his most hateful master, were actually the same person!
