Fairy Princess VS Evil God of War
Sixue, the daughter of the Immortal Emperor, was in the form of a purple-striped butterfly. She accidentally entered a rift in the evil world due to her playfulness and was rescued by Chang Ying, the son of the Evil Emperor. He healed her wounds and taught her the words of the evil world. She calmed his evil spirits and gave him a peace of mind flower condensed with immortal power.
The two fell in love in the sea of flowers in the underworld, but they didn't know that the fate of immortals and demons was already destined to be different.
