Xin, who's vowed in the name of his own ambitions to help the King, must singlehandedly face the treacherous assassin Mu Ta. Meanwhile, General Wang Yi brings a piece of tribute to the Court that seems to spell the end for all young King Zheng's hopes.

Xin discovers Ying Zheng, the young King of Qin, who's fleeing his half-brother's uprising. Piao's killer arrives to murder Ying Zheng. Xin, who's learned that Piao died serving as Zheng's stand-in, must decide which to help and which to kill.

Xin and Zheng entrust their escape to young Diao, who knows a secret way out of Heibei Village. Xin still blames Zheng for Piao's death, and even as this simmering conflict boils over, a new and deadly pursuer takes up the chase.

Fleeing pursuit, Zheng and Xin struggle with exhaustion and with each other. When they reach the appointed meeting site, there's no sign of Zheng's sole supporter, Lord Changwen . . . and the murderous tracker Mu Ta is hot on their trail.

Xin hears a tale of Piao's heroism during Wang Yi's ambush, but he also learns that King Zheng has even fewer allies than he'd been told. With little time left to forestall a civil war, Zheng decides on a dangerous path, to seek out unlikely allies.

Zheng and Xin return to where Lord Changwen waits. They make ready to ride to the capital, but they'll need remarkable strategy to overcome the terrible odds. Meanwhile, in the capital, Jie Shi has raised a vast army to face the formidable Lu Buwei.

Xin's first true campaign as a soldier comes at last, but when Wei makes a surprise move, the battle doesn't go as he expected.

Shin and Hyou are two slaves who have grown as sword training buddies and pseudo brothers with a common dream of growing up to be great generals.

Xin sets out into the western mountains with Zheng and his handful of soldiers, seeking the aid of the mountain king. The mountain folk, though, have little liking for flatlanders, and when he meets them, King Zheng is forced to make a perilous choice.

Zheng, Xin, and their companions arrive at the gates of Xianyang, capital of the Qin Kingdom, with a force far too small to assault such a great fortress. A stratagem may get them inside the walls, but they won't reach the Royal Court without a fight.

Zheng's supporters discuss the pros and cons of bringing the Queen Dowager onto their side, while Zheng takes matters into his own hands.

The recalcitrant and powerful Lü Buwei finally makes his appearance, accompanied by his more-than-formidable "Four Pillars." But condescension and a scarcely veiled threat of violence show right through his half-hearted show of respect to King Zheng Ying.

Xin has his first taste of fame, and Wu Meng is back to leading the Qin offensive. Will it go the same way as the last one, or does Wu Meng have a trick up his sleeve?

Just as Qin is successfully waging war with one of its neighboring kingdoms, Han, another neighbor makes its own attack against Qin.

Former servant Xin now commands 300 troops in the formidable Fei Xin Force--and the big battle he's itching for may be right around the corner.

Blocked by Wei Xing's elite crossbowmen, the forces of Zheng and the mountain folk split up. Xin accompanies a smaller force to seek out the usurper Cheng Jiao in the palace... but their way, too, is blocked, by the deadly assassin Zuo Ci and his men.

The breakaway force reaches the Throne Room, only to find the traitor Cheng Jiao guarded by his monstrous "pet," who's seemingly impervious to weapons. Ba Jio reveals a previously unseen savagery, but can he contend with the brute strength of Lan Kai?

When Xin approaches Wang Yi looking for a mentor to make him stronger, he discovers that the great general doesn't make things easy.

Xin and his comrades march into battle together again, this time under the command of the great general Wang Yi. Meanwhile, the Royal Court begins to suspect that Wang Yi has his own ulterior motive for taking on this particular battle.

The original 100-man Fei Xin Force is down to 36 men, and Zhao's generals are closing in. However, morning has dawned, and Wang Yi is on the move.

Xiang struggles to bring Zheng some shocking news. The Qin army mounts its offensive against Wei's Gaolang Castle, but is Xin in over his head?

The Fei Xin Force is eyeing tactician He Liao Diao with great distrust, but who else can think up a way to deal with the latest wave of Wei attackers?

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.

In the stronghold of the mountain folk, Zheng treats with their king, who seems determined to kill the young King of Qin in retribution for longstanding grudges. And the arrival of Xin and his companions pushes this confrontation to its crisis.

His companions battered, Xin must rise to face the monstrous Lan Kai; in doing so he learns something of the true nature of the sword. Outside, Zheng's desperate fight is interrupted by the unwelcome arrival of the mysterious and powerful General Wang Yi.
