The cannon was extremely powerful, and the evolved zombies couldn't stop it, although it was only three seconds, it killed eight evolved zombies and hundreds of ordinary zombies.

Even if the zombie leader had extremely strong control over the zombies, it took more than twenty seconds to rearrange the phalanx, but the number of evolved zombies behind the phalanx was significantly less.

Zombie leaders can not care about the lives of ordinary zombies, but the number of evolved zombies is so large, it is difficult to replenish them in a hurry after being killed.

Xiao Ran hid behind the fortifications, and when he saw that the number of evolved zombies had decreased so much, his hanging heart was slowly relaxed.

The ordinary zombies reformed the formation, but they had no intention of attacking, just blocking the outside and not letting Xiao Ran out.

Xiao Ran sneered, he didn't care at all.

Isn't it just to fight attrition and play a protracted war?

He wasn't afraid at all.

With so many zombies gathered here, it wouldn't take long for it to attract the attention of the other survivors, or even reach the ears of Luo Ji and Wei Yun.

As long as Wei Yun came over with heavy weapons, he could kill all these zombies in minutes.

Is there anything better than a zombie gathered together to wash the floor with heavy weapons?

So Xiao Ran wasn't worried at all.

After waiting for an hour, the zombies outside still had no intention of attacking, and Xiao Ran slowly retreated from the entrance.

Since the zombies refused to retreat in a short time, of course they had to formulate a response plan.

Xiao Ran, Chen An, and Bingbing had to take turns on duty, placing zombies to attack, while the other two took the opportunity to rest, kept in good condition, and could join the battle at any time.

Xiao Ran took Chen An and Bingbing to kill in the zombie group for so long, and held the first wave of attacks of the evolved zombies, which was extremely expensive, so Chen An volunteered to replace Xiao Ran, hiding behind the fortifications with a shield, and monitoring the movements of the zombies outside.

After Xiao Ran withdrew, he hurried to eat some things, and drank a pair of traditional Chinese medicine soup made by Shen Nianchuan, feeling that his state had recovered a lot, so he went back to his room to rest.

Bingbing saw Xiao Ran so calm, and her nervous heart slowly relaxed, and she ate some things like Xiao Ran, and went back to rest.

Since this is already the case, of course, we must adjust our mentality and not mess with ourselves.

In the previous life, Xiao Ran had already been accustomed to this kind of life of resting in a dangerous environment and ensuring his own state, so he fell asleep quickly, but a few hours later, Xiao Ran sat up suddenly, and grabbed the Tang Hengdao next to him, because he heard the movement outside.

Hurriedly rushed out of the room and came to the entrance, and found that Chen An was still guarding the position of the entrance, and the zombies did not attack, Xiao Ran breathed a sigh of relief, came to the location of the entrance, and looked outside.

At this time, the sky outside was already slightly bright, and Xiao Ran could see more things.

The number of ordinary zombies that originally formed the phalanx had at least doubled, and the ordinary zombies were so dense that they couldn't see their heads at all.

The movement that Xiao Ran heard just now was the sound of these ordinary zombies running to form a phalanx.

Xiao Ran didn't pay attention to these actions of the zombies, no matter what kind of movement these ordinary zombies made, as long as there were no evolutionary zombies involved in the attack, Xiao Ran could ignore them.

But just when Xiao Ran didn't think so, more than a dozen evolved zombies finally appeared behind the phalanx composed of those ordinary zombies, and behind these dozen evolved zombies was a full-brain evolution zombie with a huge head!

When he saw the whole brain domain evolution zombie, he first let out a chuckle, if it was just a whole brain domain evolution zombie, then things would be easy to do.

But soon, Xiao Ran couldn't laugh anymore, because he noticed that the head of the whole brain domain evolution zombie was actually covered with a hard carapace!

A carapace appears on the head, which is a characteristic of second-order all-brain domain evolved zombies!

The second-order evolutionary zombie is already very powerful, and it is difficult to entangle, if it is a second-order full-brain domain evolutionary zombie, then Xiao Ran's situation will be even more passive.

Xiao Ran believed that if it weren't for the fact that he had killed eight evolutionary zombies and hundreds of ordinary zombies with a machine cannon last night, allowing the second-order all-brain domain evolutionary zombies to see the power of the machine cannon, this second-order all-brain domain evolutionary zombie would definitely have led a large number of zombies to attack.

But looking at it now, the second-order all-brain domain evolution zombie chose to appear at this time, it should have to do something, otherwise it could continue to hide and not give Xiao Ran a chance to make a move.

But unfortunately, Xiao Ran guessed wrong.

After the arrival of the second-order all-brain domain evolution zombies, they actually let out a scream again, and a large number of zombies rushed towards the entrance as if they had been beaten with chicken blood.

"Noisy!"

Xiao Ran was stunned for a moment, a little puzzled how a second-order full-brain domain evolved zombie could make such a decision.

Doesn't it know that this level of offense is useless at all?

Whenever it dares to dispatch evolved zombies with special abilities, Xiao Ran dares to use a cannon to give them a hard blow.

But at this time, it is useless to think about this, a large number of zombies have rushed up, and Xiao Ran has no intention of rushing out to fight the zombies head-on, that is, to hold the entrance and resist the attack of the zombies with the help of fortifications.

Anyway, the combat power of ordinary zombies is very low, no matter how many rush in, they will be easily killed by Xiao Ran.

There are too many zombies outside, even if Xiao Ran kills more, it won't affect the overall situation, so it's better to be conservative.

However, what happened next was beyond Xiao Ran's imagination.

When Xiao Ran was dealing with these ordinary zombies that rushed up, those powerful evolutionary zombies were not idle, but took out the processed steel bars one after another, and threw them at Xiao Ran's side when the spears were long.

When Xiao Ran noticed these polished steel bars with a cold glow at the tip, he only had time to burst into a foul mouth, and hurriedly pulled Chen An to hide behind the fortifications.

Puff puff!

The steel bars fell, and those ordinary zombies who didn't have time to dodge were pierced one after another and nailed to the ground.

There was even a steel bar that pierced the fortifications that Xiao Ran had built with zombie corpses, almost hurting him.

After a round of attacks, Xiao Ran hurriedly adjusted his body and blocked the shield behind the fortifications, so that even if the steel bars pierced the fortifications, they would be blocked by the shield and would not hurt them.

After making timely adjustments, Xiao Ran's heart had already set off turbulent waves, because the wisdom displayed by this second-order full-brain domain evolved zombie had exceeded Xiao Ran's cognition.

It's not like a zombie, it's like a smart and changeable human!

No matter how smart the second-order all-brain domain evolutionary zombie is, I am afraid that it will not easily understand what parabola is, and it will not know in a short period of time that the evolutionary zombie that processes steel bars into long spears and allows the body to strengthen the direction also has long-range attack capabilities.

So, what did the second-order full-brain domain evolutionary zombie go through outside, and why was it so smart?
