I'm invincible since the end of the world

As the team went deeper, the number of zombies they encountered also increased.

This time, they encountered the largest number of zombies, reaching more than 20,000.

Of course, 20,000 zombies don't put much pressure on them.

So when the major mercenary groups received Lin Xinghai's order to slow down the killing of zombies, they had nothing to worry about.

In many places where hand cannons were used for bombing, they instead used Ripper rifles for burst shooting.

In this way, while saving points, the speed of killing zombies will also be slowed down.

Of course, there is a limit to this slowdown. They can't really let these zombies gather more and more, so these mercenaries will not be lenient at all when they shoot.

After 15 minutes of fighting, the number of corpses was reduced to less than 10,000.

And due to the decrease in the number of zombies around, the speed at which the zombies are gathering is getting slower and slower. According to this progress, this zombie wave will be wiped out in at most 10 minutes.

However, what made Lin Xinghai depressed was that the "predator" 5 kilometers away seemed to be just here to watch the show. After watching it for 15 minutes, there was no follow-up action.

Just when Lin Xinghai thought there was no chance again, an observer suddenly reported loudly: "Sir, we found another 'predator', no, it was two 'predators', and they were both approaching quickly. ”

Lin Xinghai immediately became happy after hearing this, "How far is it from here?"

The observer said: "There are only 7 kilometers left of 8 kilometers."

"Very good! Keep an eye on it." Lin Xinghai geared up. Being able to kill three "predators" was pretty good.

However, nine times out of ten things in the world are unsatisfactory.

Not long after, the observer whispered: "Sir, the three 'predators' did not continue to move forward after reuniting."

"What!" Lin Xinghai frowned and quickly came to the optical observation equipment. The person in charge of the operation was also smart and adjusted the projection without any instructions.

When Lin Xinghai saw these three "predators", he really had no intention of getting close. They seemed to be just here to watch a show.

This scene made Lin Xinghai feel a little pained.

But soon, he saw from the projection that these three "predators" were moving again. Although they did not continue to approach, they all began to roar.

Although no sound can be heard, it can be judged from the shape of their mouths that the other party is indeed roaring continuously.

"Adjust the camera and observe the zombies around them." Lin Xinghai said quickly.

Everyone else had a bad feeling when they saw this scene.

And soon this premonition became a reality.

With the three "predators" at the center, the surrounding corpses were gathering at a rapid pace. This gathering speed was not comparable to those of zombies spontaneously organizing themselves.

"Something is not good. They are going to launch a zombie wave. Should we withdraw?" Zhang Yue looked at Lin Xinghai and asked solemnly.

It takes time for the opponent to launch the zombie tide. Even if they launch the zombie tide, it will take time to get here. They have time to evacuate, and their quick movements will not even delay cleaning the battlefield.

Lin Xinghai frowned at first, but suddenly a sneer appeared on his face, "It seems that these mutated zombies are really underestimated. I wanted to scare the monkeys. But I didn't expect that now they are testing their strength."

Zhang Yue's heart tightened, "What do you mean?"

"The mutated zombies obviously don't dare to attack now, so they launched a zombie wave to test our current strength."

"If we retreat now and show a hint of cowardice or a sense of defeat, I can guarantee that tonight, the sub-base we established will encounter a zombie wave, and at least it will be one million level or above." Lin Xinghai said.

The atmosphere in the field instantly became a little solemn. Zhang Yue swallowed before nodding slowly, "I understand. I will arrange the construction of fortifications now."

Lin Xinghai nodded, thought for a while, and added: "Remember to reserve an evacuation channel."

"Okay!" Zhang Yue nodded and left quickly.

Soon as orders were issued one by one, the mercenary groups in the clearing point became nervous.

Three mutated zombies are going to trigger a zombie wave and attack them here. This matter can be big or small.

How it will evolve in the end actually depends on how large of a zombie wave these three "predators" will be able to launch.

But this kind of thing is beyond their control. The only thing they can do is to seize the time and prepare everything.

Fortunately, they came out to clear out the zombies this time and made adequate preparations.

Especially when the mercenaries thought of the bombardment squad and its terrifying bombing capabilities, they immediately felt a lot more at ease.

Boom boom boom!

Next, the firepower of this clearing point increased instantly, and all the remaining 10,000 zombies were killed in just 5 minutes.

Then a group of mercenary groups stopped caring about cleaning the battlefield and started building fortifications directly.

Especially the entrances and exits of this shopping mall cannot continue to be blocked by those combat robots later, they must be completely blocked.

Also, they couldn't stick to this place from the beginning. They had to leave some room for return, so they learned from the plan of the previous sentinel point, centered on this clearing point, and built a line every 100 meters in front. Line of defense.

A total of three lines of defense were built. Only after all three lines of defense were breached could they retreat here to defend.

Everything was going on intensely, but they had enough manpower, and with the help of combat robots, three trenches were dug out soon.

There were also passages connecting the trenches, so that the people on the front line could withdraw at any time.

At the same time, a lot of explosives were buried in the trenches.

Of course, these explosives were not used directly to blow up zombies, but in case they were really defeated, as long as the explosives buried under the three trenches were detonated at the same time, the violent explosion could temporarily curb the attack of the zombie tide.

At that time, the artillery team would also cooperate to use artillery fire to open the way, and it should not be difficult to break through the encirclement of the zombie tide.

At the same time, they had contacted the sub-base. If they needed to break through, the sub-base would send a team to respond as soon as possible.

And all the arrangements made by Lin Xinghai were made public, so that those mercenary groups could see them clearly.

Every arrangement was a shot in the arm for the major mercenary groups.

Without any worries, the fighting spirit of these mercenaries was also aroused.

And the zombie tide was constantly approaching and growing in their busy preparations.

20 minutes after they built their positions, the vanguard of the zombie tide had arrived.

The vanguard had only 20,000 zombies, and even the large troops that came later were less than 40,000, and there were no troublesome things like violent zombies and bloody beetles.

This zombie tide seemed easy to deal with, but neither Lin Xinghai nor Zhang Yue had any intention of relaxing.

Because everyone knew that this was just the beginning. As long as the three "hunters" were still there, they could continue to summon the rest of the zombies to join this zombie tide.

So it was still unknown what the final scale would be.
