After defeating the powerful Zhao, Qin has shifted its focus towards achieving King Ying Zhengs goal of conquering the remaining six states and establishing a united China. Their first target is Wei, a smaller state that serves as a strategic stepping stone for their conquest plans. Li Xin, now commanding a 300-man Fei Xin Unit, continues to strive for greatness in order to gain recognition for himself and his soldiers, driven by the memory of those lost in battle. As Qin prepares to invade Wei, Xin faces competition from other young commanders who come from higher social backgrounds. Meanwhile, at home, the royal palace is facing internal strife as rival factions begin to position themselves against Ying Zhengs rule. Despite these challenges, Zheng and Xin remain determined to leave their mark on history by unifying China.
