Then Gu Aotian confirmed to Luo Cheng again the use of various weapons, if you want to do a good job, you must first sharpen your weapons, if you don't master the weapons well, it is better to use a machete to beat the hammer zombies.

The two men packed their gear and walked to the end of the aisle, entered the code provided by Robert on the access control system on the wall, and the two men walked down the stairs after the floor shrinkage opened.

Robert looked at the CCTV footage and reminded them: "You have to be careful, there are several zombies near the door of this door, you must be prepared before opening the door." ”

"Roger!"

Luo Cheng stood a meter away from the door, picked up the automatic rifle in his hand, took a fighting posture, and said to Gu Aotian: "You go and open the door, I'll keep an eye on it." ”

Gu Aotian walked over and entered the password, and the airtight door slowly opened.

Sure enough, there was a group of zombies standing nearby at the door, and the zombies saw that the door was open, so they walked towards the door.

Luo Cheng was also decisive, taking advantage of the fact that the door was not fully opened, he shot directly at the zombies inside through the crack in the door, the power of the automatic rifle was very powerful, and every bullet directly penetrated the body or head of the zombie.

Gu Aotian also joined the battle and shot at the zombies inside with the submachine gun in his hand, but the rate of fire of the submachine gun was too fast, and the recoil from his arm made him unable to grasp the trajectory at all, and the bullet flew directly up after hitting the zombie's body.

Luo Cheng shouted: "Press the gun, big brother, keep the muzzle low, if you can't grasp it, don't use continuous shooting." ”

Luo Cheng stood motionless like a zombie executioner, and the bullet casings fell to the ground one after another.

Gu Aotian listened to Luo Cheng's words and changed the design mode to triple shots, so that the rate of fire was reduced and the stability was also improved.

In less than five minutes, more than twenty zombies were lying down in the entire aisle, and the glass walls of the aisle were covered with flesh and blood, like hell.

The two men stopped firing, and a wisp of white smoke was still coming from the muzzle of the gun.

Gu Aotian: "Fatty, let's go in, pay attention to observe carefully, some zombies may not be dead yet, remember to mend the knife, don't fold it here again." ”

This is also what Gu Aotian learned from American dramas, after all, sometimes seeing is not necessarily believing, and only when you have confirmed it is really safe.

It was too wasteful to use bullets to replenish the gun, and the two of them simply pointed a dagger directly at the heads of all the zombies lying on the ground.

Luo Cheng wiped the blood on the dagger with the clothes on the zombie's body: "That radish said that there are more than sixty zombies in total, and there should be about twenty left now, why don't you see other zombies?" ”

Gu Aotian was also wondering about this question, it stands to reason that the other zombies should have come over long ago when they heard the battle here.

He simply asked Robert from the Bluetooth headset, "Mr. Robert, where are the remaining zombies?" ”

There was no sound in the headphones, and it was terrible to be quiet for a while.

Gu Aotian turned his head to look at Luo Cheng, and found that the blue indicator light on the Bluetooth headset on his right ear was not flashing, and then he took off his own look, and sure enough, it was the same.

He said helplessly: "Fatty, this Bluetooth headset is out of battery..."

Luo Cheng: "I'll take the test, how long have I been down, this is out of power, this is a copycat product!" ”

Seeing that the headphones were out of power, Gu Aotian threw them away directly: "Then now, we can only rely on ourselves." ”

In the laboratory on the second basement floor, Robert looked embarrassed: "Sorry, guys~ I forgot to charge." ”

Then Robert wanted to see where the other zombies were, and he pulled up the surveillance footage from the other locations, one of which made his jaw drop in shock.

I saw that the remaining zombies were standing around the mutated zombies, and the mutated zombies were letting those zombies bite all over its body.

Robert exclaimed, "What are they doing!!" ”

This scene also attracted Cheng Huan and Cheng Hong, and the three of them stared at the picture on the screen.

The sharp-eyed Cheng Hong said: "Sister, look, those zombies seem to be sucking the blood of that mutant zombie!" ”

Cheng Huan approached the screen and took a closer look, and it was indeed like Cheng Hong said: "Mr. Robert, what the hell is going on?" What are these zombies doing? ”

Robert looked incredulous, he shook his head and said to himself: "I've never seen a scene like this, I've been surprised by the appearance of a mutated zombie here, but now... Please forgive me for not being able to explain this scene to you for a while!! ”

Cheng Huan looked nervous, and continued to ask Robert: "Then you said before that the mutant zombie bit those special forces members who were injected with antivenom and caused the mutation, so is it possible that the blood in its body can also mutate those zombies who suck the blood of its virus?" ”

This question asked by Cheng Huan Robert also thought of it just now, but...

"No~ It shouldn't be possible, I've observed that mutant zombie, its mutation cycle is three months, I think those zombies who have sucked its virus blood won't mutate so quickly~"

Cheng Hong: "Sister, then do you think Brother Aotian and Fat Brother will be in danger now?" ”

Cheng Huan's face was ugly: "Mr. Robert, is there any other way to contact them?" ”

Robert looked embarrassed: "I'm sorry~ Except for those two Bluetooth headphones, I can't contact them anymore." ”

"Gotta find a way to inform them!"

At this time, Gu Aotian and Luochen below continued to walk forward after mending the knives to those zombies, and there were no zombies of special forces members found in the group of zombies just now, just as they walked forward about three meters, Gu Aotian suddenly grabbed Luo Cheng.

Luo Cheng looked at Gu Aotian: "What are you pulling me for?" ”

Gu Aotian said softly: "Fatty, did you hear any movement?" ”

Luo Cheng's eyebrows squeezed together and listened carefully: "No, did you hear any sound?" ”

The fat man's frightened ears had not fully recovered at this time, so he did not hear.

Gu Aotian pulled Luo Cheng down to the wall and whispered to him: "I don't know where there is a strange sound in front, it should be the remaining group of zombies, we have to be careful, and when we will fight, we will clean up that mutated zombie first!" ”

Capture the thief first capture the king, take down the strongest first, and the rest is not enough evidence, this is a trick that Gu Aotian learned when he fought Resident Evil in the university dormitory, fight the boss first, otherwise, those little monsters will drag you to death sooner or later!

In the corner where the two of them couldn't see it, the group of zombies were taking turns sucking the blood of the mutated zombies, and an amazing mutation was taking place in those zombies that had been sucked.

The blood of the virus spreads and spreads all over the body of the zombies, and finally reaches the brainstems of those ordinary zombies that have already shrunk into a little bit, like plants and trees nourished by rain, growing rapidly.
