The Legend of Qin Season 1 Episode 1 E 1

In 421 B.C., Ying Zheng conquers the six kingdoms of China and unites them into one nation. He is called Qin, the first emperor of China. The union is fragile, however. While the empire has been established, pockets of resistance to Qin rule have emerged. To ensure stability, Ying Zheng sends his military forth to crush all opposition. Gai Nie, the best swordsman in the six kingdoms, Master of the Ghost Valley Sect, and a former agent of Ying Zheng, refuses to follow the new regime. Along with Tian Ming, the orphaned son of an old friend, they flee with the Emperor's army hot on their trail. Along the border of Qin, Gai Nie, armed with the famous sword Yuan Hong, stands alone against a cavalry of 300. Li Si, the Prime Minister of Qin, suggests a new strategy to dealing with Gai Nie, so the Emperor sends him to recruit Wei Zhuang, whom Gai Nie defeated to become the Master of the Ghost Valley Sect. Now the Master of the League of Assassins, Wei Zhuang agrees to Qin's terms so that he can take vengeance on Gai Nie. Meanwhile, Tian Ming and the wounded Gai Nie are surrounded by rebels from the defeated nation of Chu. Shao Yu, the brash young heir to the royal family, bests Tian Ming, but quickly discovers that the boy and the wounded Gai Nie mean them no harm. Suddenly, Wu Shuang Gui, a monstrous agent of Wei Zhuang's, attacks the group.
