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 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, 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 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.

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.

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.

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.

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.

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.

Xin, Bi, and the breakaway force, fighting to reach the throne room, face the seemingly invincible Zuo Ci in the "Right-Side Dragon" corridor, while outside, the King and Lord Changwen hold out against Si Shi and Wei Xing.

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?

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.

A face-off with Jiao Cheng awaits, but before that can come, Zheng Ying, facing death at General Wang Yi's hand, must convince the "Strange Bird of Xin" that his vision of the future makes him a worthy successor to his great-grandfather, King Zhao.

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'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.

The battle heats up as Wei's forces bring out their trump card. This isn't going to be a fair fight--but luckily, Xin isn't looking for one.

The Fourth Army's victory against the chariots gives Lord Biao an idea. How far can he push behind enemy lines if the infantry's survival is no object?

Just when it seems the battle on the She Gan Plain is finally going their way, Qin's forces are suddenly surprised by the advent of three generals: their own, the enemy's... and one who's not even supposed to be there!

Xin has his very first conversation with a true general, and Wu Qing of Wei and Lord Biao of Qin are finally batting each other in earnest.

Lord Biao and Wu Qing are both fighting all-out, and whoever wins this one-on-one battle also wins the war.

Xin learns some things about Qiang Lei's past, and Diao has to make an important decision about the future.

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

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.

Zhao's master tactician Li Mu is forced into negotiations with Qin's crafty Lü Buwei. What will the outcome mean for the future of their kingdoms?

Xin confronts Li Mu, the man who orchestrated Wang Yi's battlefield defeat, while Diao touches base with Kaine. Zheng reveals his future plans.

Xin gets a lead on a big battle that could propel him up the ranks to general, but soon learns he's not the only young, ambitious warrior around.

As the Fei Xin and Yu Feng Forces play at one-upmanship, Si Shi proposes a surprising potential ally in Zheng's power struggle with Lü Buwei.

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

Zheng tells Xiang about his days as a young hostage in Zhao, and about the unexpected people called upon to get him safely back to the Kingdom of Qin.

The flashback to young Zheng's escape from hostile Zhao to his Qin homeland reveals the startling effects of the mental and physical abuse he'd endured.

Zheng's flashback shows the lengths to which a black marketeer was willing to go to make sure he got home and became King of Qin, against all odds.

As Zheng and his supporters await word from the Inner Palace, the Queen Dowager reveals where her allegiances lie. Xiang is put in a tight spot.

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?

Wang Ben's Yu Feng Force tries unconventional tactics to gain ground in the siege of Gaolang Castle. Lü Buwei's actions start to have consequences.

Xin settles into his new position as the Qin army prepares for a battle that could change the face of China. Qiang Lei discusses her plans with Xin.

The battle at Shanyang is underway. Xin and his fellow temporary thousand-man commanders must face the fearsome Lian Po--and the deadly Lun Hu.

As Wang Ben and the Yu Feng Force do battle with Lun Hu, the Fei Xin Force is called into battle. A devious strategy takes the Qin army by surprise.

The Qin army is at a standstill in their battle against Wei--until Qiang Lei devises a workaround. Will her idea be enough for them to claim victory?

Meng Ao's lieutenant Huan Yi takes the battlefield with some real tricks up his sleeve. The Wei army must scramble to beat him at his own game.

After Huan Yi's masterstroke, Meng Tian suggests the Le Hua, Yu Feng, and Fei Xin Forces team up in the hopes of leaving their own mark on history.

Meng Tian skillfully brings all three special forces together in his plan to eliminate Lun Hu, but will the shrewd assassin fall prey to his scheme?

Bi gets a surprise visit and a new role in the battle against Wei, while Wang Ben and Xin fight against time to put an end to the masterful Lun Hu.

Lieutenant Wang Jian's plot comes to fruition with help from the skillful Commander Bi, but the battle--and the battle of wits--is far from over.

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.

Wa Lin devises a way to hurry along the generals' duel. Li Mu and Lord Chunshen discuss a new strategy, while Wa Lin shows her hand at long last.

The Qin army is riding high when Wa Lin's elites arrive at Hangu Pass. An unpredictable Qin general steps in to assist. Diao is cautiously optimistic.

The royal capital of Xianyang is feeling the heat as outpost after outpost falls in the south of Qin. The most ominous question: Where has Li Mu gone?

Qin's Lord Biao confronts Li Mu at the center of his clever whirlpool trap, where he meets a savage warrior with a history of battling great generals.

Xianyang is in disarray as Li Mu's army approaches and King Zheng goes missing. Qin formulates a strategy around a southern outpost--its last hope.

It's up to King Zheng to convince the people of Zui to fight, defending Xianyang and Qin itself. Li Mu's arrival makes them second-guess themselves.

The first day of any battle is a high hurdle to clear, even without civilian troops. Li Mu employs unique tactics overnight to gain the upper hand.

Xin's training with Qiang Lei comes in handy at Zui. Zheng continues to rally the civilian and veteran troops--until something goes terribly wrong.

The castle town of Zui is struggling to stand strong in their drawn-out battle, suffering serious setbacks that put Li Mu on the path to victory.

Reinforcements arrive for Qin, and not a moment too soon. But even the most ferocious mountain warriors are no match for one of Zhao's Three Greats.

An exhausted Xin draws on what remains of his strength to face Pang Nuan. The end of the war with the coalition army is in sight, but at what cost?

The country of Qin celebrates its victory in its capital Kanyou, with a ceremony rewarding the warriors who have distinguished themselves in a notable way against the coalition. On the other hand, Kyou Kai, who left the Hi Shin unit to avenge his sister Kyou Shou, is getting closer and closer to his target, Yuu Ren...

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.

Qin chancellor Lü Buwei schemes to gain more influence in the Royal Court. Zhao makes a surprising move, prompting Cheng Jiao to make one of his own.

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.

Diao meets with Kai Meng in the Wei camp while Xin and friends scramble for a way to get her out. The Yu Feng Force faces another brutal Fire Dragon.

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.

A supersized Ai army approaches an underdefended Xianyang. The Queen Dowager and Lü Buwei both have their own epiphanies during the crowning ceremony.

Zheng refutes his chancellor's notion of ideal government and articulates his reasons for a united Middle Kingdom. Xin gets turned around in Xianyang.

The court ladies make a run for it when their safety is compromised. Shang Lu's ailing army is just barely keeping the enemy out of the royal 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.

The Fei Xin Force is sent out to join forces with General Huan Yi to conquer Heiyong in Zhao, but their opponent--and the terrain--won't make it easy.

As the fighting gets underway in Heiyong, Qiang Lei's scouts make a disturbing discovery, Xin goes for broke, and Huan Yi brings out the big guns.

Tactician He Liao Diao racks her brains to find some way out of an impossible situation so the Fei Xin Force can complete their mission-critical task.

Lieutenant Yuan and his men work hard to fulfill their vital role. A surprise appearance by a charismatic figure greatly affects the tides of battle.

He Liao Diao switches gears to share some hard-earned power with Huan Yi's forces--all the general has to do is take it. Qiang Lei's caretaker speaks.

Qiang Lei learns about Ji Hui's background. Frustration mounts in the face of Huan Yi's inaction. Qing She decides to take matters into his own hands.

The Battle of Heiyong reaches a fever pitch as Huan Yi's men target Qing She--who in turn is looking to slay Xin. Xin comes up with an audacious plan.

Qing She considers his debt to Li Mu as he faces Xin on the battlefield. Devastating events drive Ji Hui to pursue a new tactic in defending Heiyong.

Huan Yi's top commanders question his latest bizarre decision. Wei Ping has a crisis of conscience. Xin and Qiang Lei react to a gruesome discovery.

The standoff with Huan Yi continues until Wei Ping intervenes, but Xin learns a disappointing fact that paints his loyal friend in a whole new light.

General Huan Yi shows that his cutthroat reputation is well deserved as he tightens the screws on Ji Hui and forces him to make an agonizing decision.

Cai Ze returns to Xianyang with not one, but two unexpected guests. Zheng is put on the spot about his plans for a post-unified Middle Kingdom world.
