Qinglu'er is a great demon who has been practicing for more than 400 years. He has a very powerful master. Logically speaking, he can walk sideways in the entire demon clan, but his master does not allow him to leave the mountain.
He only has the sect in his memory and has never met his parents. He wanted to search and ask the other person if he had been abandoned.
Until one day, he finally got a chance to leave the mountain, and his master asked him to deliver a letter to the Lord of Demon City. On the way, he met a human being who was pretending to be a demon. The two of them hit it off and started a journey of mutual growth.
Purpose: Mutual redemption
