Three Kingdoms: I, the Emperor of Wei, am loyal and pure!

Zhang Yan's 100,000 Black Mountain Army was a chess piece laid out by Cao Ang long ago.

As long as Cao Ang thinks about it, he can make Zhang Yan's Black Mountain Army rebel and Gongsun Zan's rear be on fire.

However, although the Black Mountain Army has 100,000 troops, its combat effectiveness is uneven.

If you want them to play their greatest role, you also need the cooperation of the main force of Cao's army. The combination of regular troops and surprise troops can achieve the purpose of causing the enemy's troops to collapse among themselves!

"Send my general's order to block the gap in the Zhang River and cut off the water in the river protecting Yuan Jun's camp first!"

In front of all the generals, Cao Ang first issued such a military order.

Previously, he assigned Gongsun Zan and others to divert water from the Zhang River around the inside and outside of the defense line, creating many rivers to protect the camp. They even stored water in low-lying areas. Swamps were formed to hinder the cavalry's charge.

After this period of time, the weather turned hot, and the rainy season had not yet arrived.

The water vapor in those swamps was almost evaporated.

Only those guard camps that were replenished by the water of the Zhang River remained. The river will hinder Cao Jun's attack.

Therefore, the gap in Zhanghe River was blocked first, and part of Yuan Jun's defensive measures in"583" was abolished first. At

Yuan Jun's camp, Shen Pei watched Cao Jun begin to block Zhanghe River. The gap caused the water level of the camp guarding river to lose its water source. The water level began to slowly drop, and his eyebrows could not help but frown tightly.

However, there was nothing that could be done about it.

Send troops to stop Cao Jun from blocking the gap?

That would be like a meat bun beating a dog. There is no return!

When the combat power of the two sides is extremely unequal, a small group of Yuan's troops spread out to serve as a target for Cao's army.

"With this move, Cao Jun was probably preparing to attack.

Send an order to the entire army to prepare for the attack.

All arrows, gold juice, rolling wood, stones, etc. must be prepared!

All ministries are preparing reinforcements, and they must also be prepared to make up for them at any time!"

Shenpei looked at the generals of Yuan

Jun beside him and ordered with seriousness. After explaining Yuan Jun's side, Shenpei was a little worried about Gongsun Zan.

Gongsun Zan was capable, but sometimes he was too much. Self-willed!

Shenpei was worried that Gongsun Zan would be blindly confident because of the smoothness of the previous defensive battle at Yi Jing, leading to him despising Cao Ang.

Therefore, Shenpei came to Gongsun Zan's defense line in person, met with Gongsun Zan and said:"Marquis of Yi, Cao Ang has begun to cut off the Zhang River Zhishui must be preparing to attack.

Marquis Yi has never fought against Cao Ang before, so he must be prepared and cautious."

When Gongsun Zan heard this, looking at his almost impregnable defense line, he immediately smiled and said:"Sir, you are so careful that you actually come here to warn me personally.

I already know everything about Cao Ang's reputation.

This line of defense is even more solid than at the time of Yi Jing.

Don't worry sir.

Inside and outside the defense line, in addition to strong bows, hard crossbows, rolling wood and stones, there are countless light and dark traps.

Even the confidants in our army who are not allowed to deploy defense plans dare not wander around in the camp.

If that kid Cao Ang dares to attack, he will suffer a big loss in my trap!"

Gongsun Zan's voice was very confident.

Because he did have such confidence.

The Battle of Yijing successfully blocked Yuan Shao's army's attack for several years, making Gongsun Zan enough to rank among the masters of defensive warfare in this era!

What's more, when he defended At the time of Yi Jing, Gongsun Zan only had tens of thousands of elites left, and his troops were limited.

At this time, in addition to his own troops, Gongsun Zan also had 100,000 vassals of Zhang Yan's Black Mountain Army. As well as more than 200,000 allies of Yuan's army inside and outside Ye City!

That's enough! With an army of more than 400,000 people, with deep ditches and high bases, backed by a fortified city, they were just like the Zhao State that held firm during the Battle of Changping. As long as they did not take the initiative to attack, even if the enemy had twice the strength, they would never be able to break through Gongsun Zan. The camp!

When Shenpei saw Gongsun Zan's confidence, he wanted to say something else, but he also felt that anything he said would be superfluous.

After all, according to Gongsun Zan's layout, the defense lines of the two armies' camps were indeed The layout is impeccable.

Various overt and covert defensive measures are layered on top of each other. Even our own people don't dare to walk around randomly on weekdays. Not to mention the enemy who doesn't know where they are?

Even if the enemy attacks at night, it may be at most In other words, if you capture the first line of defense, you will suffer heavy losses from the traps in the camp, and then the strength of the defense lines behind will be ready to meet the enemy...

Shen Pei is also a person who knows soldiers, so he naturally understands , Gongsun Zan and him have done all the means they can.

Although Gongsun Zan is a headstrong man, he really can't see any flaws in the way of defense...

So Shen Pei felt relieved and returned. Yuan Jun's camp.

At the same time, the Black Mountain Army's defense line was in Zhang Yan's camp.

Zhang Yan's troops and horses were mostly arranged in the outer defense line because they were larger in number but less elite.

But there were also some elite troops distributed in the inner layer.

Also In other words, Zhang Yan's troops were present from the outer defense line to the small town where Gongsun Zan's army was located.

As an ally of Gongsun Zan, Zhang Yan naturally obtained the defense plans of various light and dark defenses in the camp.

At this moment, the record The defense map showing all the defenses within the defense line was in front of Zhang Yan.

At the same time, apart from Zhang Yan, there were only a few people in the tent.

Their superficial identities were soldiers under Zhang Yan's command.

But in fact, they were from last year. The Jin Yiwei who was arranged by Cao Ang to be next to Zhang Yan

"In the past few days, we have verified that this defense map is accurate.

Now that the general is preparing for a general attack, this defense map is sent to the general immediately to help the general capture Shenpei and Gongsun Zan as soon as possible!"

Zhang Yan lowered her voice and looked at the few imperial guards in front of her...

The few Jinyi guards nodded, and one of them said:"Tonight I will lurk out in the dark and send the news to the general.

As for this defense map, there is no need to carry it.

Just in case they are discovered, Gongsun Zan and Shenpei I will change the defense.

All the defenses are already in my mind."

After listening to the Jin Yiwei's words, Zhang Yan looked sideways:"This picture is complicated. Even if I have this picture, I can't remember it all when I close my eyes. But you said The defense plan is already in my heart, which is unbelievable. Please note that this matter is related to the general's grand plan and is not a trivial matter!"

The Jin Yiwei knew that Zhang Yan was worried, so he was not angry. He just picked up the weapon in front of Zhang Yan. Using pen and ink, he closed his eyes, and then drew a defense map in front of Zhang Yan.

Every important location on it, including bright and dark sentries, light and dark traps, etc., is not missing. Even the proportions are the same as in the original picture.

Seeing this scene, Zhang Yan was shocked.

He originally thought that the Jin Yiwei sent by Cao Ang were just spies responsible for liaison.

But the Jin Yiwei's move shocked Zhang Yan with this man's photographic memory!

"Everyone says that General Cao is a young man but one of the most versatile in the world!

I never thought that a secret agent sent by the general could have such a photographic memory and the ability to draw pictures with his eyes closed!"(To read Baoshuang novels, go to Feilu Novel Network!)

Zhang Yan said with emotion, and finally came to a conclusion:"The general has really many talents under his command.

Fortunately, I voted for the general early.……"

The Jin Yiwei smiled lightly and did not take any credit.

Little did they know that most of Jin Yiwei's job was this kind of job. In order to keep it secret, of course he rarely carried letters, pictures and other evidence with him.

All the information is stored in your mind!

Only those who can achieve 1.3 like this can be the real Jinyiwei!

Amid Zhang Yan's shock and joy, night fell.

As a member of Zhang Yan's camp, the Jin Yiwei was assigned by Zhang Yan to guard the perimeter overnight.

Taking advantage of this opportunity, he secretly left Zhang Yan's camp and returned to Cao Ang.

In front of Cao Ang, he perfectly redrawn the defense plans he had memorized in his mind, with every detail correct.

When he saw the defense map and learned about Gongsun Zan's specific defense deployment, Cao Ang couldn't help but nod secretly.

Gongsun Zan can indeed be called a master of defense.

The various defenses in his camp have brought defensive warfare to the extreme.

Without this defense plan, even a forceful night attack would cause Cao's army to suffer heavy losses.

But now, with this defense plan and Zhang Yan as an internal response,[]

So in Cao Ang's eyes, Gongsun Zan's iron-barrel defense can be regarded as a broken wall with leaks on all sides and holes everywhere...

There is no secret at all!.
