The special soldier Zhao Huan traveled through time and became a guard of Prince Kang's palace in the late Northern Song Dynasty. He wanted to live a stable life, but he saw the Jin soldiers marching south, and the mountains and rivers were shattered. He used modern knowledge to create gunpowder and train a new army. He took control of the military step by step from an unknown soldier, helped Zhao Gou ascend the throne, and turned the tide. There is Qin Hui plotting in the court, Jin Wushu's cavalry on the battlefield, and Yang Zaixing's loyalty and Li Qingzhao's tenderness beside him. Zhao Huan was tossed between intrigues and wars, vowing to rewrite the shame of Jingkang and let the Song Dynasty cavalry break through the Helan Mountain gap.
