Superstar From Age 0 - Chapter 437:

The genius cultivator Lin Xuanzhi didn’t let down the world in his past life, yet he only betrayed a single Yan Tianhen.

It was only when he had been backstabbed and killed by his closest friends, teacher and fellow disciples that he knew what kind of unforgivable crimes he had committed.

After he gained the huge opportunity for rebirth, the Lin Xuanzhi who had climbed back up from hell swore to cherish the person that he had betrayed in his past life.

As a kind of punishment, the wings of a demon king were cut, and he eventually lost all of his power. To get back his power, he made a deal with the angel.

If the woman got pregnant, all of his sins would be forgiven, and he will regain all his powers. But he didn’t think that knowing her would be an adventure for him as the king of demons in the human realm.
