In addition to the geographical location, the Nanguan city wall of Shenwu Pass is not opened, and the defense is also very tight.

And all the people who came to the city wall, looked out. It can be seen that on the short 121-meter-long city wall, there are no less than 20 sentries, 10 spider combat robots and more than 20 anti-aircraft machine guns, keeping vigilance and standing guard in the cold wind of January.

You know, it's not wartime, and there are no zombies attacking.

It's just an ordinary vigilance, and the arrangement of these many people shows the importance that Shenwuguan attaches to the defense of the Nanguan city wall.

And, to the great admiration of the Americans, such a cold weather! These sentries standing guard at Shenwu Pass were still standing straight and straight like javelins, not moving at all. His gaze was as sharp as an eagle's eye, always fixed on the valley in front of them. This kind of discipline is really inferior to the Americans.

In fact, they all knew that in the valley in front of them, there were many secret sentinels who were constantly closely monitoring the situation in and out of the valley. But they didn't let up in the slightest.

Because they all know that in the face of zombies, humans only have one chance!

With the powerful contagion ability of zombies, any carelessness of letting a zombie or a human with a zombie virus into the settlement may put the entire settlement in danger.

Beside them, a Gatling machine gun fixed to the city wall stood silently.

It seems that as soon as there is any wind in the valley in front of them, these Gatling guns will immediately show their hideous side, and their roar will resound through the valley!

On one side of the city wall, which is only 121 meters, there are more than 20 Gatling guns on guard at the same time. It stands to reason that this kind of firepower is enough to deal with any emergencies.

Because as soon as the shots rang out, other officers and soldiers who were resting within the city walls and in the mountains on both sides would quickly enter the position and start the battle.

But Shenwuguan still felt that it was not enough.

Therefore, in addition to the more than 20 soldiers standing guard on duty, Shenwuguan also arranged 10 spider combat robots and more than 20 six-pack anti-aircraft machine guns on the city wall, which are also on guard at all times.

Needless to say, there are more than 20 six-mounted anti-aircraft machine guns, and the anti-aircraft firepower is absolutely superior. Each anti-aircraft machine gun has 6 barrels firing bullets at the same time!

And the 10 spider battle robots attracted the attention of the Americans and other people in most of the capital and Yanhuangcheng.

Everyone knows that these spider battle robots are not good-looking.

The hideous muzzle, the Gatling, and the huge and shining war knife guaranteed that the zombies who dared to rush to the wall of Shenwu Pass would know in minutes that only the zombies who obediently stayed under the city wall were good zombies.

In addition to these weapons, in fact, there are no less than 20 remote-controlled machine guns installed on the outside of the wall of Shenwu Pass Nanguan.

These machine guns can be operated in the control room of the Nanguan City Wall of Shenwu Pass.

It's just that these weapons are not yet visible to the people who have just climbed the city wall.

***************

"Everyone, this city wall under our feet is currently the forefront of our Shenwu Pass's defense against the zombie attacks in the south."

After the people who had just gone up to the top of the Nanguan city wall of Shenwu Pass took a look at the environment here, Qin Cheng began his introduction.

"It has a total height of 83 meters and is divided into three layers......"

"Three floors!" Speaking of this, David couldn't help but be a little puzzled. In his impression, the city walls are all straight up and down, how can there be any talk of several layers and several layers. He couldn't help but wonder, "Is it possible that the inside of this wall is hollow, like a building?" So if the zombie is smashed with a stone, won't it be smashed? ”

Soon, though, he knew he was wrong. (Actually, what he thought was not wrong, there is indeed a hollow place in the Nanguan city wall of Shenwu Pass, but it is behind the city wall.) There are two floors that are hollow and are used for garrisons. Anyway, the top of the city wall is 25 meters thick, which is not less than a few meters. Defense is sufficient. ）

At this time, Qin Cheng smiled and introduced, "Yes." In fact, this wall, on the side facing the valley, is divided into three levels! ”

So saying, he took everyone to the city wall, and the Americans looked down and understood. It turned out that under the highest wall, there were two other walls that were slightly lower than this one.

Qin Cheng explained at the same time: "We are now standing on the highest one of the walls of our Shenwu Pass Nanguan, with a height of 83 meters and a width of 25 meters, the second floor below is 77 meters high and 2 meters wide, and the third layer is 71 meters high and 2 meters wide. The height difference between each level of the wall is 6 meters. More troops can be deployed here to maximize the firepower in front of the wall. ”

Both David and Regs nodded.

Indeed, because it happens to be the location of the mountain pass, the wall here is not wide, and if there is only one wall, then the firepower arranged is limited after all.

But if you add two more layers under the walls, you can deploy more troops.

At this time, Qin Cheng continued to introduce: "The total length of our city wall is 121 meters. However, if you take into account the defensive positions on the peaks on both sides, and the guard posts placed in depth on both sides, the total length of the defensive front is 12 kilometers long. ”

Regis couldn't help but ask curiously, "Then have you also set up positions on the peaks on both sides?" ”

"Yes!" Qin Cheng said: "Although the peaks here are steep, and for some places that are easy to climb, we have also made artificial repairs to make them natural city walls. But it's not absolutely insurmountable. At least for reptilian and flying corpses, they can easily get past them. ”

Qin Cheng continued: "So everyone look at the peaks on both sides of the valley in front, on the peaks on both sides of this valley, we have each arranged a hidden position about 1 kilometer long. And a large number of troops were deployed in it for defense. If the zombies attack, we can rely on this city wall and the positions on both sides of the valley in front of us to form a pocket array, form a three-sided flank, and wipe out the zombies in the valley. ”

Hearing that there were hidden positions on the peaks on both sides, Registon looked in surprise in the direction that Qin Cheng was pointing. Because at the beginning, he didn't even notice that there were positions on the peaks on both sides.

At this time, he took a closer look, and sure enough, he really found some clues.

It turns out that these positions are hidden under the mountain peaks, and they are underground positions. After clever camouflage, only a number of small shooting holes were exposed.

In addition, in order to prevent zombies from climbing, the peaks on both sides have been repaired manually. So if you don't look at it carefully, it's really hard to find.
