Wow, the copy is gone... I'll rewrite it, I guess it won't be exactly the same.
The Xuanyuan clan is a clan with magical powers. Their power comes from their symbionts, a group of demons who share their bodies and lives.
The Xuanyuan clan is powerful, but also sad. The stronger their power, the more serious the misfortunes they bear.
Xuanyuan You is also the proud son of the Xuanyuan family, but he cannot change the fate between strength and misfortune.

This is the story of a family that uses its body and soul as a sacrifice to live in symbiosis with demons...
