Xiao Ran silently watched the battle on Wei Yun's side from the top of the building, and he didn't mean to make a move at all.

Before this, Xiao Ran obviously had the opportunity to tell Luo Ji and Wei Yun about the siege of the zombies in advance, but Xiao Ran didn't do it, mainly because he didn't trust Luo Ji and Wei Yun.

If Luo Ji asked him, how did you know that there would be a zombie siege, what would Xiao Ran say?

You can't say you're born again, can you?

Even when facing Chen An, Xiao Ran chose to lie, let alone face Luo Ji and Wei Yun.

Since you can't explain it clearly, don't make trouble for yourself.

Besides, since the zombies can launch such a large-scale siege, they must have been fully prepared for a long time, and if the zombie leaders see that the official survivor base in Los Angeles is prepared, they are likely to change their strategy, either continue to accumulate strength and delay the launch of the zombie siege, or forcibly subdue more zombies and join the battle.

Whatever the case is, it's not what Xiao Ran wants to see.

Only by following the original historical trajectory can Xiao Ran have the opportunity to benefit from it.

So no matter how difficult the battle was on Wei Yun's side, Xiao Ran would not be touched in any way.

Anyway, according to the normal historical trajectory, Luo Ji and Wei Yun held on for three days and were not completely wiped out, and now that their combat power has improved so significantly compared to their previous life, how could they be easily destroyed by zombies?

Sure enough, just when Xiao Ran was thinking this, Wei Yun had already retreated with people to the vicinity of the residential building near the entrance.

Although Luo Ji and Wei Yun didn't expect the zombie siege to happen suddenly, they had discussed how to deal with it if they encountered a large number of zombie attacks, including how to deal with the first line of defense being breached.

These residential buildings near the entrance are no longer ordinary residential buildings, but have been renovated, the entrance and windows on the first floor have been re-reinforced, and there are many shooting holes reserved above the second floor.

Near the entrance, there were less than three hundred heavily armed fighters who entered the three residential buildings under the command of Wei Yun, while those reserves entered the first floor of the residential buildings, responsible for guarding the entrance and windows of the first floor.

The three residential buildings are arranged in a zigzag shape, two in front and one in the back, which can support each other, and there is no shooting blind spot, which can effectively stop the attack of zombies.

A large number of zombies rushed in and tried to attack the three residential buildings, but they were covered by strong fire and suffered heavy losses, so the battle entered the stalemate phase again.

The three residential buildings support each other and are difficult to deal with, but the area covered by the fire is not large, and the zombies can completely ignore the three residential buildings and go around to attack inside.

But after they bypassed, Wei Yun could also lead people to launch a wave of counterattacks against the zombies, which could not only kill a large number of zombies, but also effectively disrupt their rhythm, so it was not enough to simply bypass them.

This is not only the case on Wei Yun's side, but the situation near the other three entrances is similar.

There are too many zombies and the attack is too fierce, and in a hurry, humans can't resist at all, so they can only retreat to favorable terrain and look for opportunities.

Xiao Ran saw that the two sides were at a stalemate again, and felt that the leader behind the zombie should almost appear.

After all, the battle has been going on so far, all relying on the command of the evolved zombies and the instinct of ordinary zombies to fight, and the role of the zombie leader has not been played at all.

If the zombie attack goes well, it doesn't matter if the zombie leader shows up or not, but now it is obviously hindered, and if the zombie leader doesn't come out to brush up on his presence, it won't be appropriate.

Sure enough, when Xiao Ran looked towards the square, he found that three evolved zombies had already appeared over there.

The three evolved zombies are all in the direction of body strengthening, with a height of more than two meters, thick limbs, and a triangular position after entering the square. Behind the three evolutionary zombies, a full-brain domain evolutionary zombie entered the square surrounded by hundreds of ordinary zombies.

Xiao Ran's eyes lit up, and he finally waited!

However, Xiao Ran didn't make a move, but looked towards the roof of the office building again, since the whole brain domain evolution zombie came to the square, there should be no movement on the other side of the office building, right?

But Xiao Ran took a closer look and found that there were a large number of zombies gathered in the office building, which made Xiao Ran unable to understand.

The whole brain domain evolution zombie has appeared, what are you still doing in the office building?

Xiao Ran couldn't understand it, and he didn't dare to make a rash move, in case the office building was not suspicious, his side would be exposed as soon as he made a move.

Anyway, Wei Yun and they can still hold on, so wait a little longer.

Xiao Ran picked up the binoculars again to observe, and found that after the whole brain domain evolution zombies appeared, those zombies who rushed into the Los Angeles survivor base immediately changed their tactics.

They didn't choose to bypass Wei Yun and the three residential buildings they were in, but instead sent six evolved zombies to lead three thousand ordinary zombies to surround these three residential buildings.

Since Wei Yun and the others want to hide in the residential building and not come out, then there is no need to come out, anyway, there are a large number of zombies, and a few zombies can surround these three buildings by casually dividing them, and the other zombies can continue to go deeper inside.

It was just a simple change that changed the offensive and defensive situation, making Wei Yun fall into passivity.

If Wei Yun and the others want to fight back, they must first find a way to break through the defense line composed of these three thousand zombies, but without the support of favorable terrain, why should Wei Yun just go head-to-head with so many zombies?

Once they rushed out of the dormitory building, the Whole Brain Domain Evolution Zombie would definitely not give him another chance to let him go back.

But if you don't go out, a large number of zombies will rush into the depths of the official survivor base in Los Angeles, where people are not good at fighting, and they don't even have weapons to take advantage of, how to face the zombies who suddenly rushed in?

Wei Yun couldn't help but get anxious, Luo Ji handed over all the warriors to him, just to let him guard the entrance and prevent the zombies from rushing in, but he couldn't even do this.

Thinking of the human tragedy that was about to be caused by a large number of zombies rushing into the depths of the official survivor base in Los Angeles, he couldn't wait to rush out and fight the zombies.

Xiao Ran's gaze moved away from the residential building where Wei Yun was, his face still did not change at all, and he carefully observed the movements of the square and the office building again.

The full-brain evolution zombies in the square don't seem to be moving, but powerful evolutionary zombies continue to come to it, and after a few seconds, they leave again, and then the zombies that attack the official survivor base in Los Angeles have a new change.

There is no doubt that it is this full-brain evolutionary zombie who is directing this battle.

And there is still no movement on the other side of the office building, I don't know what the situation is over there.

Xiao Ran put down the binoculars and began to adjust the mortars and machine guns.

There were still ten shells left in the mortar, and the firepower was obviously insufficient, but Xiao Ran deliberately asked Ah Fu to bring some more shells from the machine gun when he set off, which was a full 500 rounds.

Even if the mortar can't kill the whole brain domain evolution zombie, the machine gun is firing with all its might, it should be about the same.

After all, mortars and machine guns are not something that the whole brain domain evolution zombies can withstand.

After adjusting the angle of the mortar, Xiao Ran called Bingbing over, told her how to fire the mortar, and asked him to shoot all the shells as soon as possible after he fired.

Bingbing nodded, although she hadn't touched a mortar before, this thing was relatively simple to operate, and she didn't need to aim, just keep firing the cannon.

Xiao Ran picked up the AMR, locked the whole brain domain evolution zombie through the scope, adjusted his breathing slightly, and quickly pulled the trigger.
