In the age of the Warring States in ancient China, a former servant named Xin climbs the military hierarchy with a single ambition: to become the supreme commander of all realms. Serving beside King Ying Zheng of Qin—who aims to bring China together and quell the turmoil—Xin commands his own detachment, the Fei Xin Brigade, on the front lines.
After seizing authority from the powerful Chancellor Buwei Lü, King Ying Zheng starts constructing a new unified legal order with backing from pivotal allies such as strategist Changping Jun and the legalist Li Si.
When Qin initiates a campaign to annex lands from Zhao, their push is stopped by the astute tactician Li Mu. In reply, Changping Jun charts an audacious scheme: to slip past Zhao"s fortifications and assault the pivotal city of Gyou, situated near Zhao"s capital.
To execute this daring operation, a formidable coalition army is assembled—directed by tacticians Ou Sen (Wang Jian), Kan Ki (Huan Yi), and the warrior queen Yo Tan Wa (Yang Duanhe). They are joined by Qin"s next‑generation leaders: Xin"s Fei Xin Brigade, Mou Ten (Meng Tian)"s Gaku Ka Unit, and Ou Hon (Wang Ben)"s Gyoku Hou Unit, each functioning autonomously.
The brutal clash for Gyou commences, with Qin"s destiny for unification hanging on the outcome.
