The story takes place at the end of the Dayin Dynasty - the collapse of rituals and music, the separation of princes, raging border troubles, and frequent natural disasters. Young Shi Pojun was originally an orphan struggling to survive in a civilian camp in the northwest. He got lost in the ancient battlefield "Duanjiyuan" and strayed into the sealing tomb of the ancient general "Wu Liewang", awakening the heroic spirit "Xuanjia" who had been silent for thousands of years. The military soul recognizes its master and bestows the "Nine Chapters of Military Mirror" and the "General Star Resonance" power that governs all armies, allowing it to command elite Yin soldiers, predict the battle situation, and inspire soldiers to fight. He rose from the grassland, defeated the enemy with cunning plans, and governed the army with iron rules. He repeatedly made extraordinary achievements in pacifying the Western Qiang and regaining the northern territory. However, he gradually found out that he was actually the legitimate son of the late emperor. He was contracted by the powerful Prime Minister Shen Ke in a civet cat-for-prince scheme and was exiled to the people. The main plot revolves around the three-step progression of "establishing military merits to rectify the name, gaining military power to clear the emperor's side, and uncovering old cases to return to the court." Finally, he led a million troops to force the palace in front of the "Chengtian Gate" in the imperial capital, beheaded the treacherous prime minister, eliminated the puppet emperor, regained control of the jade seal, and rebuilt a new iron-blooded system integrating military and political affairs.
