How Zhang Yi Lured King Huai of Chu Into the Trap

In the last episode, the first major vertical alliance had looked impressive from a distance but dissolved under real pressure. King Huai of Chu had carried the title of alliance leader without fully committing his strength. Once defeat came at Hangu Pass, every state began looking for its own exit again.

For Qin, one danger still mattered above all.

Qi and Chu must not become stable partners.

Qi had wealth.

Chu had vast land and armies.

If those two powers truly held together, Qin's road east would become far more difficult.

So King Huiwen of Qin searched for the right tool to break that possibility.

The tool was Zhang Yi.

Qin Sent Zhang Yi to Chu Because Chu and Qi Together Were Too Dangerous

After his return from Wei, Zhang Yi found King Huiwen deeply worried about exactly one strategic pairing.

Wei could waver.

Han and Zhao could shift.

But if Qi and Chu stood together, Qin would be forced to calculate far more carefully.

So Zhang Yi was given the task he suited best.

He went to Chu carrying heavy gifts, rich fabrics, and the full display of Qin diplomatic grandeur.

King Huai heard that Zhang Yi himself had arrived and was pleased at once. In his mind, such a high-ranking envoy from Qin must surely have come with flattering intent.

So he welcomed him personally and treated him with considerable honor.

Zhang Yi did not waste time.

He quickly put the one thing most likely to heat the king's imagination directly on the table.

Did the king want six hundred li of Shangyu?

King Huai did not need to say much aloud.

The thought was already burning in him.

Zhang Yi then offered the bait in its most seductive form:

Qin could give that land.

Chu would not need to spend troops or blood for it.

It needed only to break with Qi and turn toward Qin instead.

This struck exactly where the king was weakest.

Land without war. Gain without cost. Such an offer is hard for a ruler not to want to believe.

And so King Huai agreed far too quickly.

Wise Men at Court Saw the Trap, but the King Had Already Swallowed the Reward in His Mind

Chu was not completely devoid of clear-eyed men.

Chen Zhen saw at once that something was wrong. Qu Yuan did not trust Zhang Yi's words either. Their advice was straightforward:

Qin may be negotiated with, but not trusted in advance.

If land is really to be exchanged, Chu should wait until the territory is physically handed over, its own officials are installed, its posts are held, and its taxes are being collected.

Only then should it sever ties with Qi.

That was the prudent way.

The problem was that King Huai had already mentally taken ownership of the six hundred li.

Once a man has put the prize into his heart, advice starts to sound like obstruction.

Worse still, the king moved too fast.

Before Qin had transferred anything, he had already sent envoys to insult Qi and rupture the relationship openly. By the time Chen Zhen's warnings sharpened, the damage was already half done.

He could only sigh.

As long as Zhang Yi delayed skillfully, Chu would keep walking itself deeper into the pit.

Back in Qin, Zhang Yi Pretended to Be Ill and Left Chu Hanging

To prevent Qin from backing away, King Huai even sent a general with Zhang Yi to supervise the handover in person.

That sounds cautious.

Yet caution is useless against a man who knows exactly when to work and when to perform.

Once back in Qin, Zhang Yi staged an injury at a banquet, then claimed to be bedridden and absent for three months. He neither went to court nor met the Chu representatives.

All the Chu side could do was wait.

And in that waiting, King Huai drew an extremely dangerous conclusion.

Perhaps Qin was not hesitating because it intended to cheat.

Perhaps it only doubted whether Chu had really broken fully enough with Qi.

So he doubled down.

He sent another mission to Qi, said even harsher things, and broke the relationship still more completely.

Only after the rupture was unmistakable did Zhang Yi leisurely reappear, as if recovering from illness, and call in the Chu general.

Then he delivered the knife.

What six hundred li of Shangyu?

I promised six li.

And not even state land, but only my own estate.

The Chu envoy was stunned.

This was not a slight reduction.

It was proof that the whole thing had been a deception from the beginning.

Humiliated in Public, King Huai Turned to War for Face

When the news reached Chu, King Huai exploded.

What he could not endure was not simply the loss of the land.

It was that everyone in court now knew Chen Zhen had warned him, Qu Yuan had warned him, and he had ignored them all while personally wrecking relations with Qi.

When rulers lose face in that way, they often reach for the most obvious compensation.

War.

So King Huai attacked Qin, hoping to recover by the sword what he had lost by gullibility.

But Zhang Yi had dared to deceive because Qin had already prepared what came after the deception.

At Bluefield, Chu was badly defeated.

That battle awakened King Huai only halfway.

He now saw that Zhang Yi's tongue had never been operating alone.

Behind the sweet promises stood the entire strategic structure of Qin's horizontal alliance policy.

The bait was speech.

The real blade was Qin's army.

After Defeat, Chu Reached Back Toward Qi, but Broken Trust Never Fully Heals

After the disaster at Bluefield, King Huai moved quickly to repair relations with Qi.

Qi also understood that Chu had been manipulated by Zhang Yi, so on the surface it was willing to reconcile. Qi knew perfectly well that it too would struggle alone against a stronger Qin.

But alliances, once cracked, never return to innocence.

States can clasp hands again.

They rarely give their backs again without hesitation.

King Huai had already shown that for the appearance of free land he was willing to cast aside an ally. Qi could work with such a man again.

It could not fully trust him.

And splitting that kind of damaged trust was exactly the sort of thing Qin did best.

Even After the Fraud, the King Was Still Following Qin's Rhythm

Before long, Qin let another message be heard.

If Chu would once again break with Qi, perhaps the matter of Shangyu could be discussed afresh.

At this stage King Huai claimed he no longer cared about land.

He wanted Zhang Yi.

But that itself showed that he was still moving within the framework Qin had created for him. The object had changed from land to a man, yet he was still following the path laid down by his opponent.

Qin actually sent Zhang Yi to Chu.

At first he was imprisoned, and the scene looked dramatic, as if he had placed himself in extreme danger. Yet money and influence came with him. Gifts flowed to the king's favorites and to the circles around the palace. Arguments were made skillfully:

If Zhang Yi were killed, Qin would rage.

Chu might suffer again.

King Huai still remembered Bluefield.

Under pressure from those around him, his anger softened into hesitation.

Was killing one man really worth summoning another Qin war?

That hesitation saved Zhang Yi's life.

In the end, the king released him.

And once again, the path used to receive him had further damaged Chu's relationship with Qi.

The man was not killed.

The humiliation was not avenged.

The ally was pushed still farther away.

What Zhang Yi Really Stole Was Chu's Judgment

Later, after King Huiwen died, Zhang Yi himself would not remain forever secure in Qin. The next king preferred more direct force and less of this twisting style of diplomacy.

But "Zhang Yi deceives Chu" was already enough to secure his place in history.

Because what Chu lost here was not only one negotiation and not only one campaign.

It first allowed itself to be hooked by the phrase "six hundred li of Shangyu." Then it cut its own cord to Qi. Then it tried to regain face with war. Then, after defeat, it tried to patch the old alliance. When that patch was still weak, it turned again at Qin's prompting.

On the surface, this looks like Zhang Yi being an extraordinary liar.

At a deeper level, it was King Huai repeatedly believing what he most wanted to hear.

Many states in the Warring States age began losing not first through swords, but through judgment.

If you accept an enemy's sweet promise as truth and treat your own loyal warnings as noise, then by the time armies meet, much of the damage has already been done.
