Su Xin, a soldier guarding the Great Wall, finally triggered and activated the god-level sign-in system he carried with him after he had been guarding the Great Wall for a hundred days. As an opening reward for defending the city for a hundred days, Su Xin gained the overwhelming "overlord power" and was instantly transformed, possessing Xiang Yu's invincible courage. When foreign enemies invaded the Great Wall, the originally ordinary Su Xin relied on the terrifying divine power emerging from his body to kill all sides on the battlefield. He swept away the enemy with absolute strength and became famous in one battle. From then on, he started an invincible journey to guard the border and sweep across the heavens.
