The first attack failed, and the zombies did not immediately organize a second attack, but quickly gathered the ordinary zombies and continued to form an encirclement of the official survivor base in Los Angeles.

The official Los Angeles Survivor Base did not suffer any casualties in the first defense, and the morale was still the same, and many people's expressions began to relax.

As long as they stay in the same state as before, no matter how many zombies come, they will deliver food.

But Xiao Ran didn't think so, since the zombies dared to launch such a large-scale siege, there must be some hole cards, and it was just a simple temptation just now.

On the surface, it seems that the official survivor base in Los Angeles has the advantage and has killed a large number of zombies, but in fact, less than three thousand ordinary zombies have been killed, and the most that evolutionary zombies are injured is not affected by combat power.

Tens of thousands of zombies were dispatched this time, and less than three thousand casualties were nothing to zombies.

As long as the zombie leader does not die, the zombies will not have the word that their morale will collapse, even if there is a rain of bullets in front of them, the zombies will not hesitate to charge.

In this comparison, you can see how fierce the attack Wei Yun and the others will face next.

Sure enough, half an hour later, the sky was getting darker and darker, and the lights had been turned on on the official survivor base in Los Angeles, and the zombies had also taken the opportunity to launch a second attack.

This time, the zombies also learned smartly, and instead of rushing up in a swarm, they dispersed to form an echelon, and the direction of the attack was not simply to lock the position of the entrance, but to send half of the zombies to charge the entrance to contain the human warriors guarding the entrance, and the other zombies rushed to the vicinity of the wall, using the method of stacking arhats to try to climb over the wall.

Seeing this, Wei Yun hurriedly ordered the power grid to be turned on, and the zombies who had just climbed over the wall were electrocuted one after another, and their bodies fell stiffly.

But the power grid can't completely stop the zombies, because Wei Yun and they didn't find a professional high-voltage engineer, and the power grid voltage set up is insufficient, even if the zombies are electrocuted, they will not be easily killed.

Besides, the coal reserves on the side of the thermal power plant are limited, and for the sake of long-term consideration, Luo Ji will not invest too much in the fence grid, at most it will serve as an early warning.

After all, Luo Ji would never have thought that he would face the siege of tens of thousands of zombies so soon.

As soon as the electrocuted zombie falls, more zombies climb up, electrocuted, fall down again, and then zombies climb up.

And so on and so forth, and in just a few minutes, the power grid on the fence began to loosen.

Seeing this, Wei Yun was anxious, but there were only more than a thousand fighters in the official survivor base in Los Angeles, scattered at four entrances, and there were less than three hundred people at each entrance, once a large number of zombies rushed over the wall, the consequences would be unimaginable.

"Reserves! Get ready for battle! ”

Wei Yun shouted, and rushed to the edge of the wall with a long knife in hand.

The reserves spontaneously formed by the survivors responded one after another and rushed forward with Wei Yun.

Although the members of the reserve team have all experienced battles, they have not received professional training and have not been issued firearms, so they can only rely on cold weapons in their hands to fight.

At the beginning, when only a small number of zombies came in over the wall, Wei Yun was able to lead people to defend easily, but as more and more zombies came in over the wall, Wei Yun and they felt the pressure.

A single zombie is not scary, but when there are enough zombies and they are not afraid to die, the situation begins to change.

After all, the reserve team is not a well-trained warrior, the will to fight is not strong enough, and the combat ability is not so strong, and when they start to engage with a large number of zombies in hand-to-hand combat, their hearts begin to waver.

Once someone is injured or pounced on by a zombie, the person next to them will be frightened and become restrained and afraid to fight.

As time passed, this situation became more and more serious, especially when the evolved zombies actually rushed in over the wall, relying on their strong physical fitness, easily tearing through the defense line composed of human survivors, and there were also a large number of zombies rushing in, the reserve team's will to fight began to fade.

Wei Yun knew that it would never work to go on like this, so he could either find a way to prevent the zombies from coming in through the wall, or he would organize a retreat as soon as possible and rely on the favorable terrain to fight the zombies.

The former is impossible, and now we can only retreat and look for favorable terrain.

But retreat is not just a matter of turning and running, once these reserves have run, the zombies who have come in over the wall will attack the warriors at the entrance.

Even if the warriors at the entrance were all well-trained and heavily armed, they would definitely not last long if they were attacked on their backs.

Therefore, Wei Yun can retreat, but he must find a way to keep those warriors at the entrance, let them retreat first, and then he will take the reserve behind the palace.

To put it nicely, it is the queen of the palace, but in fact it is an outcast.

No one sacrificed their lives to stop the zombies' attack, how to ensure the safe retreat of others?

Therefore, while resisting the attack of the zombies, Wei Yun moved towards the entrance with the reserves, and at the same time asked his henchmen to notify the soldiers on the other side of the entrance to organize a retreat as soon as possible.

As soon as the second attack began, Wei Yun and the others were a little overwhelmed, which made Xiao Ran a little surprised.

Although the official Los Angeles Survivor Base was almost completely wiped out under the zombie siege in the previous life, this time the strength of the Los Angeles Official Survivor Base has been so greatly improved, why is it still so vulnerable?

In Xiao Ran's field of vision, a large number of zombies launched a suicidal attack in the direction of the entrance, while other zombies rushed to the vicinity of the wall in a swarm, using their bodies to build a slope, so that the zombies behind could step on their bodies and rush to the wall.

I have to say that although zombies have low intelligence, their execution is several times stronger than that of humans.

If it were a human attack, this would never be the case.

It is precisely because a large number of zombies use their bodies to build a slope that the wall with a height of nearly three meters has almost become an ornament, and a large number of zombies easily cross the wall and attack the humans hiding in the wall.

In the face of this situation, Xiao Ran also had no choice but to retreat and find a favorable terrain again.

It can only be said that Luo Ji and Wei Yun did not expect such a situation before, so they were caught off guard by the zombies.

However, Wei Yun did not mess with his position, relying on a few capable people around him to establish a line of defense, and retreated to the entrance position.

The fighters at the entrance had already received the order, and the fire suddenly broke out, suppressing the zombies attacking head-on, and then quickly packed up their equipment, joined with the reserves, and began to retreat.

With the addition of these heavily armed soldiers, the pressure on the reserve team was suddenly much less, but this was only temporary, and when a large number of zombies rushed in from the entrance position, they were in danger of being surrounded or even annihilated at any time.
