At this point, they had no other thermal weapons other than the only two high-explosive grenades left.

Gu Aotian also took out the high-explosive grenade from his body, and the two of them glanced at each other.

"Fatty, now that we have to resign ourselves to fate, will this high-explosive grenade blow up this laboratory?"

The mutant zombies at the door were too tall to be helpless against the relatively low door for a while, and could only pound the wall hard.

"Probably not, we'll hide on the side of the wall after I throw it, but you must remember not to stick to the wall, I adjusted the grenade's delayed explosion to three seconds."

As soon as Luo Cheng finished speaking, he saw Gu Aotian immediately climb to the wall.

"! It's too unkind!! ”

Then Luo Cheng opened the safety of the high-explosive grenade and threw it out of the door, he quickly ran to the side of the wall and pulled Gu Aotian to squat on the ground.

Boom!!!

The loud sound was accompanied by a strong vibration, and then the wooden door of the laboratory was blown apart, sawdust flew sideways, and a lot of wood fibers were directly inserted into the back of Luo Cheng, who was standing outside, and he grinned in pain.

The frame at the door has been blown away, blown into a big hole, the entire laboratory door is full of that single yellow slime and substance, and the mutant zombie's left leg was directly blown to pieces, and there is still some flesh and broken bones left in the right leg, its lower abdomen is full of sawdust, and there is also damage above the abdomen, but it is not dead, at this time, because its legs were blown up, it still has its upper body lying at the door of the laboratory, and the mutated zombies on its side have not received much damage because of the distance.

The upper body of the mutant zombie opened its mouth wide and let out a whining sound, and then, the six zombies next to it all ran over, and then rushed to the laboratory.

Gu Aotian and Luo Cheng were blown up by a high-explosive grenade, their heads were still buzzing, and the two of them were still in a state of stunned at this time.

Gu Aotian saw the two zombies running in, pushed Luo Cheng aside, then pinched the dagger with his backhand and stood up, grabbed the clothes of a zombie running in front of him and threw it to the ground, and then went down, put one knee against the zombie's chest, and the dagger in his hand stabbed directly into the zombie's right eye, and then slapped the dagger handle, the dagger passed directly through the zombie's head, and the tip of the knife stabbed on the ground.

And Luo Cheng also reacted at this time, picked up the dagger, and first kicked the second zombie, this zombie just knocked down another zombie running behind it, Gu Aotian saw this, directly gave up the dagger and picked up a half-meter-long, pointed and thin door in his hand, and ran over and poked it fiercely on the forehead of the zombie who was kicked by the fat man, the tip of the wooden fiber was broken, and then the rest were all inserted into the zombie's head.

Before the zombie behind it could stand up, Luo Cheng swung a dagger and inserted it into the zombie's ear, then stood up and flew up and stepped directly on the zombie's neck, and the zombie died instantly.

In the blink of an eye, the two of them had already solved the three zombies, and at this time, all the remaining zombies ran in, and there were all kinds of special forces members.

Gu Aotian picked up a table leg, the long square solid wood was very heavy in his hand, he used all his strength to smash the head of a zombie wearing a tactical helmet wearing a tactical helmet, this wood went down, the zombie's cervical vertebrae were obviously damaged, and he began to shake his head, but he still didn't forget to pounce on Gu Aotian, he flashed to the left, the zombie pounced, and then turned around and pounced on him again, Gu Aotian rounded his arm and bent over to throw a stick directly at the zombie's calf, which directly discounted the zombie's calf, I saw a piece of white bones exposed, the legs were knocked off, and the zombie stood unsteadily and fell directly to the ground.

At this time, Luo Cheng was besieged by the remaining two zombies, Luo Cheng kicked one of them away, but his feet slipped and fell directly to the ground on the back of his head, which made the fat man's eyes appear to be golden, and the other one had already walked to the fat man's side at this time, and was crawling on the ground and was about to bite Luo Cheng's neck.

Gu Aotian didn't care about the zombie whose leg was broken by him, he took two steps directly, grabbed the table leg with both hands, and swung it directly at the zombie's head like playing golf, the zombie's body tilted, and then Gu Aotian kicked it in the chest to prevent it from getting close to the fat man's body.

It knotted the zombie's head with a knot, and the edges of the table legs directly cracked the zombie's skull, but it was still not dead.

The zombie that was kicked by Luo Cheng ran directly over and threw Gu Aotian to the ground, seeing that the zombie was about to bite his chest, Gu Aotian was in a hurry and directly stuffed the table leg horizontally into the zombie's mouth, and the zombie bit the wooden stick on the table leg, unfortunately, Gu Aotian fell to the ground less than half a meter away from the zombie he had just broken his leg, and there was one on his body, and the one next to him was also crawling beside him, which made Gu Aotian kick his legs in a hurry, and the desire to survive exploded instantly, and he turned over all of a sudden, Then he used his kneecap to hit the chin of the zombie under him, which directly dislocated the zombie's jaw.

Gu Aotian turned his head and saw that the fat man didn't seem to be relieving, lying on the ground and shaking his head from side to side, and the zombie next to it came to it again like a dog skin plaster at this time.

He hurriedly grabbed the clothes that were on Luo Cheng's shoulder, and then pulled him to the corner.

In less than three minutes of fighting, the physical exertion was extremely fast, and Gu Aotian at this time only felt as if he had collapsed, and his hand holding the wooden stick was trembling uncontrollably.

Luo Cheng was still holding a dagger in his hand, and Gu Aotian took the dagger from his hand.

At this time, the three zombies were leaning against the corner, one crawling on the ground and two walking.

Gu Aotian had already figured out the key point of killing these mutant zombies with one blow, that is, to completely destroy their brain stems.

Two breaths, the two zombies were only one step away from him at this time, Gu Aotian's heart was horizontal, his left hand was holding the dagger, the wooden stick in his right hand was against his left shoulder, and then he threw the wooden stick towards the face of the two zombies with a strong force.

This stick was exerted with one hand, and because Gu Aotian didn't have much strength, he just broke the nose bones of the two zombies in unison, and made them pause in place.

Taking advantage of this opportunity, Gu Aotian directly threw away the wooden stick, took the dagger in his right hand and stabbed it diagonally into the mandibles of the zombie from the right, the dagger was pulled out, and the zombie also fell to the ground.

The one on the left bit Gu Aotian's chest directly, pushing him back to the ground again and again, and at this time he didn't even have much strength to push the zombie away.

Luo Cheng finally came to his senses at this time, he looked at it fixedly, and saw a zombie biting Gu Aotian's chest.
