I'm invincible since the end of the world

Boom!

As the vanguard of the zombie tide entered the range, the major mercenary groups were of course not polite and immediately opened fire.

The bombardment of the hand cannon and the sweep of the tearer rifle were carried out in succession, and the zombies rushing in front fell one after another.

The members of the third-level mercenary group are definitely the elite among the mercenaries. In addition, they just experienced a battle of millions of zombies last night, so it is not an exaggeration that they have rich experience in dealing with zombies.

For these mercenary groups, such a battlefield now is really not much pressure, and they even feel more relaxed.

Of course, this is not their illusion, it is indeed the case.

On the one hand, the density of the zombie tide of 20,000 zombies cannot be compared with the zombie tide of millions.

On the other hand, it is because it is daytime now, and it is the hottest noon time of the sun. The combat effectiveness of these zombies is more than 20% lower than usual.

Of course, there is also one aspect that cannot be compared with the battle yesterday.

That is, the current ammunition is all prepared by them, and the quantity is still limited.

This led to the fact that these mercenary groups did not dare to consume so recklessly.

For example, when bombing with hand cannons, they not only had to choose the place with the most zombies, but also had to discuss with the next team to avoid wasting two shells in the same place.

Even when using the tearer rifle to fire, a volley of bullets went over, and after a little pressure was relieved, they had to switch to the burst mode and fire one shot at a time.

Even those combat robots were all in close combat mode at this time, chopping with big knives instead of opening machine guns for shooting.

In this case, they saved ammunition, but the efficiency of killing zombies would naturally decrease.

Lin Xinghai stood on the top floor of the shopping mall, watching this scene with a calm expression. Although the limited ammunition would limit the performance of the major mercenary groups, it was enough to deal with such a scene.

He didn't even have any intention of intervening.

The battle was very fierce, and batches of zombies were harvested, but more zombies joined the battlefield.

Time passed slowly again, 10 minutes, 20 minutes, 30 minutes, 1 hour.

Soon the battle lasted for a full hour. At this time, the major mercenary groups were still fighting fiercely on the first line of defense, and the zombie tide had not yet broken through this line of defense.

But Lin Xinghai had to order a retreat, because the zombie corpses piled up outside the defense line were as high as a hill.

If the zombies behind climbed over the "corpse mountain" and rushed down from top to bottom, it would be a lot harder for the mercenaries below the defense line to kill them. If they continued, problems would arise sooner or later.

As the retreat order was issued, the mercenary groups retreated in an orderly manner under the cover of artillery fire.

And Lin Xinghai looked at a soldier in charge of intelligence collection in the temporary command post and asked: "How many zombies have been killed so far? What are our casualties?"

"Report to the commander, a total of 82,800 zombies have been killed. 8 people were injured, 1 person died, and 2,080 combat robots were damaged." The soldier hurriedly reported.

Lin Xinghai rubbed his forehead. The number of zombies they had killed had exceeded the maximum zombie tide estimated by the General Staff.

And it was far from over. There were still more than 50,000 zombies besieging their clearing point outside.

And the three "hunters" were still roaring continuously, calling other zombies to come.

In order to speed up the efficiency of calling zombies, the three "hunters" had even separated and roared in three different directions.

"Let the mercenary group below find a way to save bullets. This battle is probably still going to be fought."

"If we want to end it, either we have no bullets, or all the zombies nearby are killed by us. Let those "hunters" never summon other zombies again." Lin Xinghai sighed.

The others in the temporary command post heard it, and they had no way to do it.

Because it's not a question of whether you can win or not, but who can consume the other party first.

"That's right." Lin Xinghai seemed to have thought of something and ordered: "The mechas of the major mercenary groups are important combat forces. Don't let them sit idle. Take advantage of the change of defense line now and go out to fight. Use cold weapons to fight and you can also get a wave of bullets."

As the order was issued, one mecha after another rushed out from the shopping mall where the clearing point was.

At first, everyone didn't think there was anything wrong. After all, it was a very common phenomenon for mechas to rush out to kill the zombies, especially for the weak first and second level mercenary groups. This scene often occurs.

But at this time, as more and more mechas rushed out, everyone gradually felt a kind of shock.

You must know that they have 20 mercenary groups here, including 15 third-level mercenary groups, one mercenary group has 5 mechas, and there are 75 mechas here alone.

In addition to the remaining few second-level mercenary groups and several mechas from the rapid response force, at this time, there are more than a hundred mechas rushing out.

Each mecha weighs more than ten tons, and hundreds of mechas charge together. Just the rumbling sound they make when they step on the ground gives you a feeling of overwhelming tidal waves.

"This is really spectacular. I mentioned before that the military should form a mecha brigade, but unfortunately there was not enough money to expand the shelter at that time, so the matter was left unresolved."

"I didn't expect to see it here today. If we had formed such a mecha team when the zombie tide broke out last night, maybe we wouldn't have to fight so hard." Zhang Yue said with emotion.

Lin Xinghai looked at hundreds of mechas, rushing into the zombie tide, just like an elephant rushing into an ant nest. One foot could kill several zombies, and a horizontal slash of the weapon in his hand could kill more than a dozen zombies.

The efficiency of killing zombies with hundreds of mechas together is not much slower than that of more than 5,000 mercenaries.

"If such a mecha team can be formed, the combat power is indeed terrible. But in the situation last night, it is impossible to form such a mecha team." Lin Xinghai shook his head after watching for a while.

"The defense line was very tight yesterday. If the mechas of these mercenary groups are withdrawn, do you believe that the defense line will collapse in less than half an hour?"

"As for the fact that we can create a mecha brigade today, it is because the entire mercenary guild, more than half of the third-level mercenary groups are here. If it were normal times, how could such a scene happen?"

"What's more, facing such a large-scale zombie tide, mechas can only be used as a backup force. After all, driving a mecha is too much of a burden on perception, and it is impossible to maintain a long-term battle for several hours." Lin Xinghai said.

Zhang Yue opened his mouth, but found that what Lin Xinghai said was right and could not be refuted at all.

After the 15 minutes of the mecha battle, Lin Xinghai asked them to retreat. The backbone of the mecha still needs to be in good condition.

And with this 15-minute respite, the condition of the mercenaries has improved a lot.

But as the zombie tide reached the second line of defense, the battle fell into a state of anxiety again.
