My Family's Blood Is Poisonous

In this world, there is a group of people called "salary bearers". They inherit the ancient bloodline and the ancient curse - the stronger the parents, the weaker the children; if the children want to awaken, they must drain the life of their parents. The proximity of blood relatives means burning. The thicker the blood, the tighter the chains. This chain is called the "Lock of Embers." And in my body, the last firepower of the entire family is locked.
