Li Xiao led the Iron-Blooded Legion to fight bloody battles at the border for three years, but was accused of treason and was tied to the execution stand on a snowy night. The whole army knelt down weeping and pointed their guns at the firing squad, just to beg him to return to his position. And the person who personally ordered his execution that night was the confidant he brought out - Qi Jin. The moment the sword fell, the enemy cavalry broke through the pass, and the truth was like a blazing fire: Qi Jin lurked in the enemy camp for seven years, not for betrayal, but to detonate a conspiracy to destroy the empire. When Li Xiao crawled back from the mountain of corpses and sea of blood, Qi Jin's gun was pointed at him, but he said: "If you don't believe me, kill me again with your own hands."
