Season 4

The seven nations of the Middle Kingdom come to grips with the fallout of the massive coalition army war as internal disputes move to the forefront.

Tunliu rises in a revolt against the rulers of Qin--one with Cheng Jiao at its center. Old friends reunite as they're deployed to quell the uprising.

Pu Ge reveals his scheme, but doesn't take the bigger, better Fei Xin Force into account. Cheng Jiao takes a gamble as he faces the fight of his life.

A wounded Cheng Jiao confronts Pu Ge, then has a heart-to-heart with Liu Yi and shares words of wisdom with Xin as the fighting in Tunliu subsides.

Xin and Wang Ben are summoned to assist General Teng in a complex battle with Zhao, but Zhao's star general has some monumental aces up his sleeve.

As Wang Ben tangles with master spearsman Zi Bai, Ling Huang gives Wu Fengming and his officers insight into his fellow Fire Dragon's past and psyche.

The three Qin units prepare for the climactic third day of their coordinated assault on Wei's main camp in Zhuyong, with each facing a formidable foe.

There is only half a day left for the Hi Shin unit to reach Go Houmei's HQ. The strategists of both camps, Karyo Ten and Junsou, will be able to measure their talent.

Xin finds himself trapped as the simultaneous triple-strike comes together; Wei's unsuspecting main camp panics with the three Qin armies closing in.

Zhao's military minds ponder the aftermath of the Battle at Zhuyong. A powerful figure visits the Royal Court to stake a claim on the new Qin outpost.

The plans of the Queen Mother and her lover Lao Ai soon come to light: the foundation of a new state, within Qin itself. The affront is such that it calls for a response equal to it.

Wang Ben and Xin are rewarded for their actions in Zhuyong as Ai grows ever stronger. Lao Ai reflects on the path his life has taken to this point.

Ai's foreign-backed chancellor puts the Queen Dowager in an impossible position as Zheng prepares for the crowning ceremony in Qin's ancient capital.

Qin army high commander Lord Changping shows what he's made of on the battlefield with an all-or-nothing maneuver meant to immobilize Duke Rongdi.
