The plan went smoothly, and there were no zombies on the fourth floor, but some zombies ran up from the third floor on the stairs on the right side of the fourth floor and collided with Yao Shaozhi head-on.

info At a cursory glance, there are more than a dozen, but these ordinary zombies are just shrimp soldiers and crab generals for Yao Shaozhi now, with a wave of the big sword, flesh and blood flying.

At a distance of 100 meters, it was fleeting, and he quickly climbed the stairs on the fifth floor, Yao Shaozhi shouted: "It's me!" ”

Then he turned into the hallway on the fifth floor, clinging against the wall to avoid bullets.

The plan was executed very smoothly, the zombies who followed Yao Shaozhi just appeared, they were shot to death by the prepared people, and after the zombies had a corridor as a buffer, they obviously ran away a lot, and occasionally a few zombies came up from the stairs behind them, but they were all smashed down by Meng Long, who was guarding there.

About two hundred zombies were eliminated, and everyone retreated from the elevator again, while Yao Shaozhi continued to lead, and finally, when he returned to the eighteenth floor, these cannon fodder zombies were finally strangled by everyone.

Looking at the zombie corpses all over the ground, everyone unconsciously cheered, this was a miraculous battle, but Yao Shaozhi's expression was not half joyful, he knew that the real trouble had just begun at this time!

There are more than 600 zombies left outside the building, and these zombies are all enhanced zombies, they have faster movement speed, sharper claws, and more strength!

However, after all, it is in the building, if everyone still fights and retreats like this, these 600 zombies will not be able to make any waves, but what about those hunters and tanks?

The collective intelligence of zombies is very strange, once hundreds of zombies gather together, then they will communicate in a way that humans don't understand, the weak obey the strong, act collectively, and even when necessary, high-level zombies will eat these low-level zombies to replenish nutrition.

When a group of low-level zombies gathers, some of them will begin to evolve, and the evolution of this part of the zombies will be diverse, and then a few of these zombies will produce higher intelligence, Yao Shaozhi called this kind of zombie the leader.

The Commander Zombie may be any type of zombie, if there are more than one Commander in a group, then only one Commander can survive between them, and the others will become the food of the last Commander.

When the commander appears, this hierarchy among the zombies will disappear, and each zombie will only accept the order of the commander zombie, and there will be no more such a thing as letting the low-level zombies come up and send them to death first.

Although the appearance of the space-time rift has led to an acceleration of the speed of evolution, it is obvious that it is impossible to give birth to much intelligence overnight, and these zombies are now just huddled together, still fighting on their own, and do not know how to cooperate.

How big is the gap between the wisdom of the zombies and the ordinary zombies, for a simple example, if the human is hiding in the building, then the zombie faces the door of every house in a building, it is absolutely impossible to distinguish which door is the door that leads to the house where the human is hiding, if the door is closed, ordinary zombies can't distinguish the difference between going out and the wall, that is, ordinary zombies only have the instinct to hunt, and basically the wisdom is at zero.

And the commander zombie can judge where the end of the road is according to your location, whether it can be reached, ordinary zombies can be Yao Shaozhi on the stairs on both sides of the corridor to play back and forth, and once the commander zombie appears, then Yao Shaozhi will definitely be directly surrounded by zombies on both sides.

If zombies and humans are at war, then ordinary zombies will only be sent to death under human firepower, while the dominant zombies will command zombies to avoid frontal fire, which is all the wisdom of leading zombies, in other words, the ability to lead zombies is to lead ordinary zombies to encircle and intercept humans.

In other words, the zombies now are a swarm of headless flies, which also gives Yao Shaozhi and the others time to breathe!

The excitement of everyone did not last long, and as the remaining zombies began to act, everyone's expressions became a little ugly.

Since these fortified zombies only started to attack after the ordinary zombies died, they didn't know the specific location of the humans, so they climbed all over the walls, entering the building from various windows, and the tank-type zombies below also entered the building, and began to smash the wall in the direction where the smell of blood came.

"Everyone has ammunition ready, melee weapons around us, groups of four, covering each other, this is our last hurdle, as long as we get through it, we can escape, and we don't need to fear these things again!"

Yao Shaozhi encouraged the morale that began to be low, at this time, they must not lose confidence, otherwise the previous efforts will be in vain!

"I'll go out the window and show my head, give these zombies a coordinate to gather, everyone hurry to the monitoring room on the tenth floor, we need to know the location of these zombies."

Seeing that there was some confidence on everyone's faces, Yao Shaozhi hurriedly arranged tactics.

Yao Shaozhi went down with the elevator, and after everyone got off the elevator on the tenth floor, Yao Shaozhi continued to the fifth floor before getting out of the elevator.

He needs to take risks and risk his life to attract these zombies, otherwise these extremely flexible zombies will most likely use the advantage of mobility to break through the defense line once they act on their own, and once they rush in, everyone will be in chaos!

As soon as he got out of the elevator door, Yao Shaozhi encountered an enhanced zombie, this zombie did not rush to find humans, but lay on the ground and gnawed the corpses of the same kind, sure enough, there was no suppression of the zombies, and no trace of humans was found, these zombies couldn't suppress the instinctive desire for food.

Yao Shaozhi just showed up, and the zombies hadn't reacted that this was a human being, because the room was full of the smell of zombies' flesh and blood, which covered up the human smell on Yao Shaozhi's body.

However, when Yao Shaozhi raised the sword, this zombie reacted, after all, zombies don't only rely on their sense of smell to distinguish the same kind.

However, it was already a little late, and the claws of this zombie were destined to not be able to hurt Yao Shaozhi in the slightest.

"Roar, I'm here, you smash to eat me!"

Yao Shaozhi yelled in the corridor, and several other zombies were also alarmed.

The hunter zombie deserves to be called a hunter, and when Yao Shaozhi yelled, he had already exerted his limbs and shot out like a cannonball, which was a few points faster than the original zombie Lori.

However, Yao Shaozhi is not the Yao Shaozhi he was at the beginning, his eyes have evolved, and he easily captured the trajectory of the zombie, so the hunter zombie crashed into the blade of the sword by itself, turning into two pieces and falling to the ground.

More and more zombies have discovered Yao Shaozhi, and zombies from several other floors are also rushing here.

Yao Shaozhi took a deep breath, mobilized a small half of the fire ability in his body, and threw it in front of him, the corpse of the zombie turned into fuel, forming a wall of fire in the corridor, and then, Yao Shaozhi put a fire line more than ten meters away on the other side of the elevator, and a few zombies ran too fast, and rushed directly into the flames, and then fell down before they could run to Yao Shaozhi's side, and a few zombies were still retreating in the flames, and for a while, the flames on both sides were burning more and more.

Zombies are not afraid, except for flames, but all creatures will have instinctive hesitation to flames, and the more zombies evolve, the more sensitive they are to flames, so there are more and more zombies on both sides, but they all stop outside the flames.

However, as there were more and more zombies rushing in the back, the zombies in front were squeezed into the flames and began to burn wildly, and almost all the zombies in the entire building were attracted by Yao Shaozhi.
