Kingdom

All's quiet in the kingdom of Qin until not one, but three armies attack--and, as a steady stream of messengers reveals, that's just the half of it.

Cai Ze gets a royal audience in hopes of using diplomacy to save Qin. Xin tags along with Lord Biao's army. Lord Changping works to find a solution.

Qin sends its troops to defend Hangu Pass, sole gateway to the kingdom. An impressive array of military might is on display as the battle kicks off.

Lord Biao's army finds itself in a bad situation soon after fighting begins. The Wei army brings in equipment that has Zhang Tang rolling his eyes.

As the Wei army tackles the mighty Hangu Pass, the allied army of Meng Wu and Teng are battling the Chu army--and there are old scores to be settled.

Xiang Yi brings out his favorite weapon: a legendary sword. Teng takes on the fierce Chu general Lord Linwu. Xin faces a Zhao army with a grudge.

The horrors of Changping nearly two decades ago have spurred Wan Ji and his army to seek revenge against Qin, with Xianyang slated for annihilation.

A new commander takes over Chu's second army, bringing along a new strategy and a lot of confusion. The grotesque Cheng Hui of Han makes his move.

Rumors about Qin reach Qiang Lei on her journey. Li Mu calculates the best time to strike, and the Battle of Hangu Pass reaches its turning point.

Teng makes a bold decision when his army finds themselves in a bind. Cheng Hui's move pays off. Wei's Wu Fengming has another trick up his sleeve.

As Cheng Hui's poison courses through Zhang Tang's body, the mighty Qin general takes advantage of Huang Yi's cunning strategy and enters the fray.

Qin general Wang Jian seemingly vanishes, army and all, mid-skirmish with Wu Lu Duo and the Yan army. Chu's newest commander goes after Teng's head.

Meng Wu repeats his daring echelon sweep against Chu, but with a twist. Chu's massive Han Ming faces off against Meng Wu in a battle for the ages.
