Xiao Ran's movements quickly attracted the attention of the second-order full-brain domain evolution zombie, and it hurriedly let out a scream, and the high-temperature evolution zombie and the corrosive evolution zombie attacked at the same time, trying to suppress Xiao Ran's actions and prevent him from building fortifications again.

But Xiao Ran already knew how they attacked, how could he be easily stopped by them?

Under the cover of Chen An and Bingbing, Xiao Ran had already piled up the zombie corpses to a height of one meter, as long as the three of them hid behind the fortifications, it would be difficult for the high-temperature evolution zombies and the corrosive evolution zombies to hurt them.

But in this way, there is also an obvious drawback, and that is that their dodge space is severely compressed.

The second-order all-brain domain evolutionary zombies seized this point, and even ignored it again, allowing more ordinary zombies to rush up, intending to carry out the loss of sea tactics to the end.

The battle went on from the faint light of the sky to six o'clock in the morning, Xiao Ran couldn't remember how many zombies he had killed, only knew that whenever the corpses of the zombies outside the fortifications were piled up, the evolutionary zombies would rush up and move the corpses of ordinary zombies away, and then continue to let ordinary zombies attack, without giving Xiao Ran and the three of them a chance to breathe.

The high-intensity battle lasted for two hours, Xiao Ran had a good physique and abundant energy in his body, and he could still hold on at this time, but Chen An and Bingbing were about to be unable to hold on.

It's not that they can't do it, but the charge of ordinary zombies is too fierce, and they are completely not afraid of death, using their lives to consume the physical strength, energy and energy of Xiao Ran and the others.

Anyone facing such a style of play will not be able to hold on for too long.

Seeing that the zombies rushed up again, Chen An and Bingbing both leaned on the fortifications and gasped, and they couldn't care that this fortification was completely built with the corpses of zombies.

Xiao Ran took out two energy stones from his pocket and gave one to Chen An and Bingbing each.

Chen An and Bingbing looked at the energy stone in their hands, and they both showed expressions of disbelief.

They knew the preciousness of the power stones, they also knew how much Xiao Ran valued the power stones, and they knew Xiao Ran's self-centered temper, even if Xiao Ran got a lot of power stones, they would not easily share them with them.

But now, Xiao Ran gave each of them a power stone without saying anything, how could this not surprise them?

But thinking about the current situation, the two of them understand.

The zombies' attack was too fierce to give them a chance to breathe at all, and now that the three of them had reached the end of their crossbows, if they didn't get energy replenishment, they might not even be able to hold out for half an hour.

No matter how many energy stones Xiao Ran has in his hands, it is impossible for him to deal with so many zombie attacks alone, and in the end, he has to rely on the cooperation of the two of them, so Xiao Ran must give them energy stones so that the two of them can recover their combat strength as soon as possible.

Xiao Ran also took out a power stone and quickly absorbed the energy inside.

It is difficult to replenish energy and physical strength, but as long as the body is full of energy, you can hold on for more time.

Chen An and Bingbing are like each other, quickly absorbing energy and replenishing consumption.

The ordinary zombies rushed up again, and Xiao Ran and the three of them got up to fight, and found that the second-order full-brain domain evolution zombie that had been hiding behind had taken the initiative to approach to a position of fifty meters.

Although there are more than a dozen evolved zombies around the whole brain domain evolution zombies, this distance is already very tempting for Xiao Ran.

Before, he deliberately fired more than a thousand shells twice in a row, and after that, no matter how difficult the situation was, Xiao Ran didn't touch the cannon again, just to send a wrong message to the second-order all-brain domain evolution zombies: their shells had run out.

Only in this way will the second-order full-brain domain evolved zombies relax their vigilance, will they come closer, and Xiao Ran will have a chance to make a move.

However, at this time, Xiao Ran still pretended not to see it, and continued to fight with the zombies that rushed up.

It was probably the second-order full-brain domain evolution zombies who also saw the fatigue of Xiao Ran and the others, and when the ordinary zombies attacked, they actually let the four evolved zombies around them also rush forward.

With the four evolutionary zombies cooperating with the high temperature and corrosion of the two evolutionary zombies, Xiao Ran and the three of them immediately felt a huge pressure.

The three of them relied on the fortifications to fight, and they had no intention of going out, and the zombies couldn't rush in, so it was naturally difficult to hurt Xiao Ran and the others.

Seeing that an evolutionary zombie rushed to the front of the fortifications, and grabbed Bingbing with two claws, Xiao Ran raised his knife and cut off the claws of the evolutionary zombie.

Seeing this, Bingbing activated the ability to freeze the blood flowing from the wound of the evolved zombie into an ice pick and stabbed it into the head of the evolved zombie.

Originally, Xiao Ran only needed one knife to kill the evolved zombies, but to fight to this point, he actually needed to cooperate with Bingbing to do it, which shows how far his current state has fallen.

When the second-order all-brain domain evolved zombie saw this scene, he immediately became excited.

If Xiao Ran saw the change in the expression of the second-order all-brain domain evolved zombie at this time, he would definitely be surprised, because he had never heard of the second-order evolutionary zombie having a change in feelings.

Only powerful third-order evolutionary zombies or even more powerful evolutionary zombies will have emotional changes after they have intelligence comparable to that of humans.

Taking advantage of Xiao Ran's poor state, the second-order full-brain domain evolved zombies naturally had to increase their offensive efforts, and it was best to defeat the defenses of Xiao Ran and the three of them in one fell swoop and rush into the bomb shelter.

After a scream, only four evolved zombies holding steel plates were left beside the second-order full-brain domain evolution zombies, and the other evolution zombies all rushed towards Xiao Ran's side.

When Xiao Ran saw this, he didn't panic at all, but the corners of his mouth showed a little sneer.

Finally can't take it anymore?

"Chen An, go get the cannon!"

Xiao Ran lowered his voice and gave Chen An a look, Chen An nodded, hurriedly retreated to the entrance, and picked up the machine gun again, but did not come out, but continued to hide inside to prevent being discovered by the evolved zombies.

More than a dozen evolved zombies rushed up together, Bingbing's complexion changed greatly, and he wanted to retreat, but Xiao Ran suddenly turned out.

Bingbing was shocked, Xiao Ran couldn't be a brain pump, right?

Do you rush out to die at this time?

Of course, Xiao Ran didn't go to die, he took the initiative to rush out to burst out with all his strength and kill as many evolved zombies as possible, so that when Chen An counterattacked with a machine cannon, there was a greater chance of directly killing the second-order full-brain domain evolution zombies.

When he turned out, Xiao Ran had already started to run the tiger style, and a powerful momentum erupted from Xiao Ran's body, like a tiger descending the mountain.

The second-order full-brain domain evolved zombie felt Xiao Ran's momentum change, and unexpectedly subconsciously took two steps back.

With such a powerful momentum, it is also the first time it has encountered it.

Even the second-order all-brain domain evolutionary zombies had such a reaction, not to mention those first-order evolutionary zombies.
