Xu Shuo, the prince of the subjugated Chu Kingdom, was a modern special forces instructor before time travel. When the country fell, he was captured as a hostage, endured humiliation and eked out a living, and escaped while the enemy was in chaos. Fortunately, Zhao Qingwu, a strange woman from the rivers and lakes, formed an alliance, and was secretly helped by Chen Jingzhi, a veteran who was lurking in the enemy court. Xu Shuo trained his troops with modern military thinking and supported his war with business methods. He gradually gathered the remaining soldiers and recaptured the city. However, the enemy general Wan Yanlie is closing in on him step by step, and the complicated identity of his fiancée Gu Nianci makes the situation even more unpredictable. When Tiger General Tie Li, who was born as a mining slave, took Tie Li out of the enemy's secret arsenal, Xu Shuo finally launched a counterattack. From desperate situation to counterattack, he will use iron and fire to put the broken mountains and rivers back together piece by piece.
