After looking at it for a while, Peng De's eyes suddenly lit up and he said, "The angle of the barbed wire mesh is really clever."

When everyone heard Peng De say this, they became even more curious, and they didn't have the patience to continue thinking. On behalf of everyone, Wu Hai asked directly: "Teacher Peng De, why is it clever to put it up like this?"

"Haha, I won't steal this limelight. Comrade Ye Feng will explain it to you!" Peng De said with a smile. He looked at the inconspicuous barbed wire in front of him, as if he was looking at some treasure.

Hearing Peng De's words, everyone's eyes turned to Ye Feng again, and Ye Feng did not keep it a secret, and said directly: "Please pay attention carefully. Although this barbed wire is placed vertically, it still has a degree of inclination."

"Imagine what kind of results will be produced when a zombie moves against this barbed wire mesh?" Ye Feng pointed to the barbed wire mesh in front of him and spoke.

Hearing Ye Feng say this, everyone's faces changed one after another.

Ye Feng continued to speak, "Zombies are creatures without wisdom and pain. If there is food in front of them attracting them, they will move forward straight."

"However, this barbed wire has an inclined angle. If it is straight forward, it will constantly rub against this barbed wire."

"As long as they do not change direction, as they move forward, this inclined barbed wire will gradually cut their throats, blood vessels and even spines as they continue to move forward."

Every word Ye Feng made everyone's eyes brighter, and until finally everyone's faces appeared with excitement.

At this moment, they understood why Ye Feng had dared to say before that when dealing with zombies, a barbed wire mesh was used well, and the effect was even more powerful than a submachine gun.

"The placement angle is indeed clever." Wu Hai couldn't help but sigh: "If you just put it horizontally, then when the number of zombies is too large to a certain extent, you can still break the barbed wire."

"But if you place it in a tilt like this, the barbed wire will have much less tension, and the possibility of being pulled off will be greatly reduced." Wu Hai also thought of one of the benefits of placing it like this.

"Yes, in addition to this, there is another advantage, that is, you can use these barbed wire to separate the zombies that gather together, so that the threat to our soldiers will be much less. It's simply a killing of one's own goal." Peng De also praised at this time.

"Teacher Peng praised it, you just didn't change your mind. Although the physical strength of zombies is far greater than that of humans, they are just a group of brainless things. As long as you understand the behavior of zombies, it will be much easier to deal with in the future." Ye Feng said politely.

When everyone heard Ye Feng say this, they laughed. Then, without Ye Feng's instructions, everyone, including Peng De, began to get busy.

It is already 1:30 pm, and there is not much time left for them. They must complete the breakthrough before the sun sets.

Otherwise, when these zombies get crazy at night, it will be too late. I am afraid that the barbed wire placed in the Xin'an base will be twice as many as possible, and it will be impossible to withstand it.

Ye Feng asked someone to bring paper and pen, and then he quickly drew it on it. Every line he drew was the range and distance that these barbed wire mesh needed to be arranged.

The sketch in the direction of the South City Wall was soon drawn by Ye Feng.

As you can see from the sketch, as this line is formed, it seems like a big eight character extending towards the distance.

In this way, the influx of corpses can be divided into three parts.

There are also many thin lines in this eight characters, and each of these lines represents a deadly barbed wire mesh.

With the completion of Ye Feng's sketch, all the soldiers began to get busy. Even under Peng De's order, the preparation camps on the other three walls were drawn over.

Ye Feng immediately began to draw the next sketch, and he wanted to turn the entire base into a zombie strangle field.

The barbed wire on the truck was quickly unloaded by soldiers, but these barbed wires were tied together and had formed a curve. It was not easy to straighten them, so soon there was not enough manpower.

At this time, Peng De finally made a decision and ordered some of the evolvers in the survivor base to be summoned.

At the same time, this matter was made public and the order to retreat was officially issued.

With the issuance of Peng De's order, the entire survivor base was in full bloom.

Most of the survivors have hardly closed their eyes since last night because they are afraid that after they fall asleep, the tide of corpses will rush in and they will not have time to escape.

And now when they knew that the military headquarters had already come up with a retreat plan, they were immediately excited.

In fact, many well-informed survivors already know what the situation is outside, and also understand that this time, the Xin'an City base is probably doomed.

Now that I hear such news, how can I not be excited? Many evolvers have signed up to help.

As for the other survivors, under the orders of the soldiers, they all began to prepare and waited to retreat at any time.

As the saying goes, there are many people and great power. When more than 3,000 evolvers are coming to help, the speed of building defensive positions soars.

Although Ye Feng has drawn many lines on the sketch, with the help of these survivors, it should be completed in two hours.

"Okay, Commander Peng, this is the sketch of the defensive position. Now we should start preparing the second step, attracting the zombies on the other three walls here." Ye Feng handed the drawn sketch to Peng De and said.

"Comrade Ye Feng, I wonder if you have any good solutions?" Peng De asked directly.

"For zombies, the most attractive thing is blood, so I have to ask Commander Peng, you can issue an order to each of these survivors donate 100 ml of blood." Ye Feng said his request.

Under normal circumstances, blood donation is usually about 200 to 400 ml, so it will be unaffected to draw 100 ml of blood from normal people.

After hearing Ye Feng's method, Peng De breathed a sigh of relief in his heart, "Okay, no problem, I will arrange someone to do it right away."

At first, he thought Ye Feng would send someone to do bait to attract zombies like Huang Haotian.

If this is the case, he will be in a very difficult situation, but if only blood is needed, it will be much easier.
