Legend has it that when the water lily blooms on the top of Buzhou Mountain, the demons will return from Jiuyou on a road paved with thorns and bones.
Standing on the towering mountain peak, he was dressed in black and had black hair, with a long sword in his hand. He could block the attack of thousands of heavenly soldiers, but he could not withstand the sword that cut out his heart from behind.
When the blood dyed the brightly blooming water lilies red, she raised the corners of her mouth and pursed her lips into a smile: "What we demons want is nothing but your blood."
Buzhou Mountain opens, and the demon clan enters the world...
To summarize: This is the story of a demon boy who was marginalized by all living beings and became self-reliant.
