The goddess Feng Yuan's soul was damaged in the battle between gods and demons, and she fell into the mortal world, beginning a love-hate entanglement between her and the young demon Jin Lin. The Demon Lord, who was born cold and unable to love, actually developed feelings and learned to love. He would rather die than die, but also pray for the people in the world that she misses so much, just because she is the one he protects.
Purpose: Love can make the murderous Demon Lord grow in love and learn to love others. In the end, the arrogant cold demon Lord sacrificed his life to protect the people of the world.
