With the arrival of the corpse tide, the entire Xin'an City base was boiling.

The soldiers on the wall on this side of the Xin'an River were all fighting hard, stabbing spears down from the city wall, and the holes were wearing the heads of zombies.

It's just that even so, it can't stop the crazy attack of the corpse tide, and the zombies keep climbing up, and soon they are stacked layer by layer.

Two-meter, three-meter, four-meter...... Ten meters, in less than five minutes, these crazy zombies climbed to a height of ten meters, and at this time, only the last five meters were left from the soldiers on the city wall.

Seeing this scene, many of the survivors waiting above were trembling with fright, and there was a feeling of numbness on their scalps.

However, compared to them, the soldiers who had experienced the zombie siege before seemed much calmer.

A squad leader, unhurriedly, took a grenade from his waist, pulled the fuse, and threw it towards the group of corpses below.

Rumble!

A deafening sound sounded, and the group of corpses below, which was still climbing upwards, was instantly scattered by the violent shock wave.

Some zombies were even directly blown into the Xin'an River, and the zombies within three meters of it were either missing arms or legs, and a few were even blown into several pieces, and the flesh and blood were scattered everywhere.

As for the 'dirt slope' formed by the tide of corpses, it collapsed in an instant.

"Calm down, for the time being, these corpses can't rush up. There will be a batch of spears from the logistics office later, and you can kill the zombies at that time. ”

"But this thing is very heavy, at least it needs a mid-first order evolutionary to use it well." The squad leader looked down at the masterpiece he had made, then spoke to the surrounding team of survivors.

Although there was a lot of pretension in his words, it made the survivors around him feel a lot more calm.

After the attack on the corpse tide's side was blocked, the corpse group gradually moved to both sides, and as they moved, the position that needed to be defended became larger and larger.

However, the army has already prepared for this, and at all corners of this wall, soldiers and survivors have been arranged.

As for the other walls, there was no one, because they were not needed. The reason for this is related to the design of this wall.

Since the military department knows that the tide of corpses will definitely come from the direction of the suburbs, how can they not be prepared.

So in addition to the many traps here, there is also a crucial setting, that is, the position on both sides of this wall is protruding. The entire wall looks like a crescent moon.

And the tips of these two crescents extend directly into the Xin'an River.

In other words, if these corpses go along the wall to both sides, then the end result is that they go to the river.

Therefore, it is precisely because of this design that they only need to be on this wall to resist the tide of corpses, and they no longer need to be embattled as before, which greatly enhances their defense.

Of course, even with such a special design, in the face of the tide of more than 2 million corpses, there is a feeling of unbearable.

Because there are too many corpses, they are coming densely, and the killing speed of everyone can't keep up at all.

Soon, the dense zombies completely filled the ten meters from the city wall to the Xin'an River, and the countless zombies made the soldiers on the city wall feel like they couldn't start.

Of course, it was the intelligent zombies who had already picked up all kinds of stones and other things on the ground and threw them at the city walls.

Some soldiers or survivors who were attacking the corpse tide below with spears were unlucky enough to be hit by these stones, and the worst ones had their heads broken and their faces were bruised.

Even some of them are more unlucky, they are directly hit in important places such as temples, and they will be dizzy and planted on the city wall and die directly.

And in addition to these intelligent zombies, those mutated zombies will also be mixed in, and occasionally launch an attack, at which time there will basically be soldiers killed.

It can be said that the pressure on these soldiers on the city walls is unprecedented.

Everyone did not dare to slack off in any way, because as long as they slackened a little, they were afraid that the surging corpse tide below would rush up and tear them to pieces.

"Division commander, it's almost time now, you should use fire oil tactics, otherwise I'm afraid that some soldiers will not be able to withstand it." Wu Hai looked at the tide of corpses, after more than ten minutes of attack, they kept climbing, and after they had risen to a range of ten meters, they couldn't help but say in a hurry.

You know, this is not the case in just one place, but in the vast majority of this wall. Now such a situation is no longer something that can be solved with a few grenades.

"No, Ye Feng has already told me a better way." Peng De smiled mysteriously and sold a pass.

And at this moment, a herald ran over, saluted and reported: "Division commander, everything you ordered is ready." ”

"Okay, let's start executing the plan." Pender nodded and ordered.

"Yes!" The herald gave a military salute and immediately left.

And less than two minutes after he left, two battalions of soldiers rushed up with a wooden barrel, each filled with liquid. When they came up, they quickly poured the liquid from the barrel down the city walls.

The leaders sniffed lightly at this time, and immediately knew what these liquids were.

That is vinegar, one of the essential things in the last days.

Hundreds of barrels of vinegar were poured down, and the smell of vinegar instantly filled the space, and even if you took a casual breath, you could feel your nose sour.

And with the rapid spread of this strong vinegar smell, although the corpses under the city are still attacking, the offensive has slowed down greatly.

As for the corpse tide army on the other side of the Xin'an River, after smelling the strong smell of vinegar here, they stopped directly.

Although the humans on the city walls will also be attracted to them, this attraction is not too strong when they are not smelling the scent of humans.

After all, for zombies that have no intelligence, they don't know if humans are delicious, and only when they smell each other's bodies, the virus in their bodies will tell them if they need it.

And now the virus in their bodies tells them that they are extremely disgusted with the smell of the front, and this has become an instinct of zombies.

This is also the reason why when they are chased by zombies, as long as they get rid of them for a certain distance, these zombies will stop.

Roar, roar, roar!

The mutated zombies in the corpse group are constantly driving the corpse group forward, but with the interference of vinegar, the orders they give have been greatly reduced.

And at this most critical moment, the reconnaissance helicopter has been resupplied and lifted off again.

However, this time, its purpose was not to investigate, but to fly to the back of the corpses, and then one by one, blood bags were thrown from high in the air.
