After Li Dao was reborn, he was framed by Prime Minister Jian Zidao and sent to a border prison camp. He accidentally awakened the system of killing enemies and strengthening his body. His meridians are too special to cultivate internal energy, so he can only rely on accumulating physical points to exercise and subdue the villains in the prison camp to gain a foothold. During the border battles with the army, he repeatedly made military exploits, joined an elite team to complete various dangerous missions, transformed his body and acquired protective powers, broke into enemies alone, rescued his benefactor, and regained his freedom. Returning to Beijing to find his old servant, he learned that his family property had been occupied and his relatives separated. He then went to guard northern Xinjiang, repelling foreign enemies many times, rescuing important ministers and stabilizing the border defense. Li Dao cleared his grievances, rescued the distressed Princess Mingyue, joined forces with the generals to put down the turmoil, and was finally awarded the title of nobleman.
