As the team progresses, the number of zombies encountered increases.
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 that originally required hand cannons 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 in larger numbers, 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 up to 10 minutes.
However, what made Lin Xinghai depressed was that the "predator" 5 kilometers away seemed to really just come to watch the show. After watching it for a full 15 minutes, there was no follow-up action.
Just when Lin Xinghai thought there was no chance again this time, an observer suddenly reported loudly: "Sir, another 'predator' was discovered. No...it was two 'predators'. They were both there.
Approaching quickly."
Lin Xinghai was immediately delighted after hearing this, "How far is it from here?"
The observer said: "8 kilometers...now only 7 kilometers are left."
"Very good! Keep an eye on it." Lin Xinghai was gearing 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 didn't have any intention of getting close. They seemed to just come to watch a show.
This scene made Lin Xinghai feel a little sore.
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 premonition when they saw this scene.
And soon this premonition became a reality.
With the three "predators" as 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 activate the zombie tide. Even if they activate the zombie tide, it will still take time to get here. They have time to evacuate, and their quick movements will not even delay the cleaning of the battlefield.
Lin Xinghai frowned at first, but suddenly a sneer appeared on his face, "It seems that I really underestimated these mutated zombies. 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 his saliva 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 after another, the mercenary groups in the clearing point became nervous.
Three mutated zombies are about to trigger a zombie wave and launch an attack on them. This matter can be big or small.
How it will evolve in the end actually depends on how large 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 sufficient 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 at 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 have been constructed. Only when all three lines of defense have been breached can we retreat and defend here.
Everything was going on nervously, but they had enough manpower, and with the help of combat robots, three trenches were dug out soon.
There are also passages connecting the trenches so that people on the front line can withdraw at any time.
At the same time, a lot of explosives were buried in the trenches.
Of course, these explosives are not used directly to blow up the zombies, but if they are really defeated, the explosives buried under the three trenches can be detonated at the same time. A violent explosion can temporarily contain the zombie attack.
At that time, the artillery squad will also cooperate with artillery fire to clear the way, and it should not be difficult to break through the encirclement of the zombie tide.
At the same time, they have contacted the sub-base. If they need to break out, the sub-base will send a team to respond as soon as possible.
The arrangements made by Lin Xinghai were all made public, so that the mercenary groups could see them clearly.
Every arrangement is a shot in the arm for the major mercenary groups.
Without worries, the fighting spirit of these mercenaries was also aroused.
And in the midst of their busy preparations, the zombie tide is constantly approaching and growing.
20 minutes after they established their position, the vanguard of the zombie wave had arrived.
There are only 20,000 zombies in the vanguard, and even the large army coming from behind is less than 40,000, and there are no troublesome things like violent zombies and bloody beetles.
This zombie wave seems to be easy to deal with, but neither Lin Xinghai nor Zhang Yue have any intention of relaxing.
Because everyone knows that this is just the beginning. As long as the three "predators" are still there, they can continue to summon other zombies to join this zombie wave.
Therefore, it is still unclear what the final scale will be.
