Family: Starting from Genocide

The family was surrounded and suppressed by powerful enemies, the clan members were brutally killed, the mountain gate was closed, the clan leader endured humiliation and refused to fight, and the whole clan fell into despair. At this moment, the genius whose family disappeared three hundred years ago returns from the ancient forbidden land. When he stepped out of the forbidden area, what he saw was that his family was humiliated and the mountain gate was stained with blood. He doesn't know what "survival through humiliation" means - He only knows that blood debt must be paid with blood.
