They killed my family. Stole my empire. Forced me to marry their daughter as a "peace offering." For three years, I played the worthless son-in-law; beaten, humiliated, spat on by my wife's family.

That's when IT awakened; the Ancestral Blood System, a Chen family legacy that activates only when the heir loses everything. But this system doesn't give free power. It demands SACRIFICE.
