After looking at it for a while, Peng De's eyes suddenly lit up, and he said, "The angle at which this barbed wire is placed is really ingenious. ”

When everyone heard Peng De say this, their hearts became even more curious, and they didn't have the patience to continue pondering. On behalf of everyone, Wu Hai directly asked: "Master Peng De, why is it ingenious to put it vertically like this?" ”

"Haha, I won't steal the limelight, it's up to Comrade Ye Feng to explain it to you!" Pender said with a smile. He looked at the inconspicuous barbed wire fence in front of him, as if he were looking at some kind of treasure.

Hearing Peng De's words, everyone's eyes turned to Ye Feng again, and Ye Feng didn't sell it, and said directly: "Everyone, pay careful attention, although this barbed wire fence is placed vertically, it still has a degree of inclination. ”

"Imagine what happens when a zombie sticks to this barbed wire?" Ye Feng pointed to the barbed wire fence in front of him and spoke.

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

Ye Feng continued to speak: "Zombies are creatures that have no intelligence and no sense of pain, if there is food in front of them that attracts them, they will go straight. ”

"However, the barbed wire fence has an oblique angle, and if it is straight forward, it will constantly rub against the barbed wire."

"As long as they don't change direction, as they move forward, this sloping barbed wire will be like a chainsaw, gradually slicing their throats, blood vessels and even spine as they continue to advance."

Every word Ye Feng said brightened the eyes of everyone in the audience, until in the end, excitement appeared on everyone's faces.

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

"It's a clever angle." Wu Hai couldn't help but sigh: "If it's just put horizontally, then when the number of zombies reaches a certain level, the barbed wire can still be broken." ”

"But if you put it at an angle, the barbed wire will have to bear much less tension, and the possibility of being pulled off will be greatly reduced." Wu Hai also thought of one of the benefits of such a placement.

"That's right, there's another benefit, and that's that you can use these barbed wire fences to separate the zombies that have gathered together, so that there will be a lot less threat to our soldiers. It's just a win-win. At this time, Peng De also opened his mouth and praised.

"Master Peng praised it falsely, you just haven't changed your mentality. Although the physical strength of zombies far exceeds 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 a rare polite word.

Hearing Ye Feng say this, everyone laughed. Immediately after that, without Ye Feng's orders at all, everyone, including Peng De, began to get busy.

It was already half past one in the afternoon, and there was not much time left for them, and they had to finish the breakout before the sun went down.

Otherwise, at night, when these zombies go crazy, it will be too late. I am afraid that if the barbed wire fence placed in the base of Xin'an City is doubled, it will not be able to withstand it at all.

Ye Feng asked people to bring paper and pens, and then he drew them quickly, and every line he drew was the range and distance that these barbed wire fences needed to be arranged.

Soon, the sketch in the direction of the southern city wall was drawn by Ye Feng.

As you can see from the sketch, as this line is formed, it seems to be a big figure-of-eight, extending into the distance.

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

There are also many thin lines within this figure, each of which represents a deadly barbed wire.

With the completion of Ye Feng's sketch, all the soldiers began to get busy, and even under Peng De's order, the reserve battalions on the other three city walls were all transferred.

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

The barbed wire fences on the trucks were quickly removed by the soldiers, but the barbed wire was tied together and had formed an arc, and it was not easy to straighten them, so soon there were not enough manpower.

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

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

With Pender's order, the entire survivor base boiled.

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

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

In fact, many well-informed survivors already know what the situation is outside, and they also understand that this time the Xin'an City base may be in danger.

Now when I hear such news, how can I not be excited, many evolutionaries have taken the initiative to sign up and go to help.

As for the rest of the survivors, under the orders of those soldiers, they all began to prepare one after another, waiting to retreat at any time.

As the saying goes, there is strength in numbers, and when there are more than 3,000 evolutionaries who come to help, the speed of building defensive positions soars in a straight line.

Although Ye Feng carved a lot of lines on the sketch, with the help of these survivors, it should be completed within two hours.

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

"Then Comrade Ye Feng, I don't know if you have any good ideas?" Pender asked directly.

"For zombies, the most attractive thing for them is blood, so I have to trouble Master Peng to give you an order to let each of these survivors donate 100 ml of blood." Ye Feng said what he wanted.

Under normal circumstances, blood donation is generally about 200 to 400 ml, so it has no effect to draw 100 ml of blood from normal people.

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

At first, he thought that Ye Feng would send people to be bait to attract zombies like Huang Haotian.

If that's the case, he'll be very embarrassed, but if he only needs to draw blood, it's much easier.
