The demon Mo Tong was struck by lightning and fell into a mountain waterfall, waiting for someone to rescue him.
Unexpectedly, his destined person was a sick man.
He was also accidentally bound to the caring villain system. His mission is to protect the healthy growth of the sick young man, okay.
For the sake of (no matter) his (will be struck by lightning) poor (own) sake!
But he didn't expect that the scene where he walked step by step through the ice lotus would become the beginning of someone's life's redemption.
Purpose: Protect the weak and reject violence
