Reverse Heaven and others cautiously marched towards the laboratory, the entire laboratory was derived from three floors underground, the first layer was connected with heavy firearms, but there was a glass curtain wall that looked very thick, and walked to a door leading to the laboratory, entered the password, pressed the palm, and then aimed his eyes at a scanner and scanned, a white gas came out around the door, and then the door opened, and Reverse Sky took the lead in walking in, the layout inside was the same as an ordinary office, all of them were workshops, It's just that there are a lot of materials scattered on the table and on the ground, as well as daily necessities, "It seems that a crisis has broken out here, and this group of people is in a hurry when they leave!" Han Qiao glanced at the chaotic laboratory and said lightly. There must be something very dangerous happening, the people here are all elites in the army, it is impossible to be so flustered. After saying that, he pinched the gun and slowly walked inside, the first floor of the laboratory is very large, the size of two football fields, but the entrance is just like this, so after entering the first floor of the laboratory, a large number of mines, ghost mines and other large-scale lethal weapons were arranged at the door. As soon as he turned a corner, he saw dozens of zombies in the passage, gnawing around a beer belly in a white coat on the ground, it may be that the human smell of the three of them attracted the attention of the zombies, and the dozens of lost slowly turned around, and then rushed towards the three people like discovering a new continent, and took the lead in firing against the sky, as a special operations elite, he shot his head with a gun, but Han Qiao didn't shoot, he aimed like this with a gun, Zhou Wen next to Han Qiao was a beat slower than them, and also pulled out his gun and started shooting, However, compared with the accurate point shooting against the sky, the bullets shot by Zhou Wen are of no use except for fire suppression, but for zombies who only die with headshots, fire suppression or something is simply a weak explosion! "Cowardly! Why don't you shoot! I knew that I wouldn't have brought you over with Chen Bin! While shooting accurately, he scolded Han Qiao, who was just aiming but didn't fire a shot. You're the coward! Your whole family is a coward! Your position as the captain of the special operations group has gone to the belly of a dog! There are definitely more than thirty zombies in so many zombies, so don't change the magazine after thirty rounds? Don't you know the line of fire substitution?!! As soon as he finished speaking, the sound of "Titicaca" came from the gun against the sky, and after the shuttle was finished, Han Qiao immediately shot and shot, although there was no perverted one-shot and one-head marksmanship against the sky, but it was almost the same, Han Qiao used a two-shot shot, but thirty bullets, two shots and two shots were quickly over, after Han Qiao finished the last two shots, there was a perverted gunfire in his ears, the battle lasted for a few minutes, and the whole corridor was full of corpses, Because the three of them changed the steel core bullet in advance, the yield is still 100%, so there is not a complete corpse on the ground, most of the zombies who were shot against the sky are missing half of their heads, and the ones shot by Han Qiao are basically a hole in the chest and a hole in the head, but it is necessary to distinguish the ...... that were shot by Zhou Wen This is really hard to tell, Zhou Wen used a rifle as a machine gun, and the bullet didn't know where it went, and it was estimated that the inexplicable extra pile of minced meat on the ground was Zhou Wen's masterpiece.

Since there were three people and three guns equipped with this silencer, they did not alarm the zombies in other places, "Calling the mystery against the sky, the zombies have been found, they have been eliminated, and we continue to advance." "The mystery is received, everything is normal on the periphery." The mystery at the commanding heights outside was surveying around with a telescope at this time, and not a single moving target was found, and the mystery looked at Chen Bin, "You can sleep, I'll keep an eye on it." As soon as Chen Bin heard this, he put the gun next to the mystery, turned over and slept with his face to the sky. The mystery put his M200 aside and picked up the AW50 anti-materiel sniper rifle that Chen Bin had placed next to him. "Against the sky, you must not have anything to do!" The mystery is based on the gun, and I think silently in my heart.

"Take turns reloading!" After tackling a wave of zombies, the three people crouched in an inconspicuous corner, quickly filling the magazine that had just been emptied. "Big brother, is there a lot of people inside?" Han Qiao said as he looked at the zombies they had killed on the ground. "If it's just one floor, it's not much, only two thousand!" I thought about it and said. "Poof~Two thousand! That's not much, one head costs 2,000 rounds, and the three of us don't have 2,000 bullets combined! Han Qiao almost screamed. Without Han Qiao continuing to nag, he stood up against the sky and walked inside, Han Qiao had no choice but to shut up and follow, and finally Zhou Wen's face turned pale when he heard two thousand, but no one noticed it.

The number of zombies in front is much smaller, scattered, and the three of them can shoot slowly, "Attention, there is a square in front, and you will enter the second floor when you pass it!" "There should be no living people in this ghost place, let's hurry up" Zhou Wen whispered, after all, she was a girl, and she was still scared in this situation. We're going quietly now, we won't be discovered, and besides, the guns in our hands can slowly kill those zombies. Han Qiao turned around and comforted Zhou Wen behind him, "I can't die!" The cold voice came from the front, Han Qiao just wanted to scold him, but when he turned around, he was also dumbfounded, one said that the square was not big, and it was not small, and it was densely packed with people, no! It should be full of zombies! One by one, they all seemed to be asleep, still and still, "I'll wipe it!" So much, it really can't be done, what are we going to do? Han Qiao was excited, his voice was a little louder, but as a result, the zombies slowly turned around like dominoes, and then rushed over like a tide one by one. Run, run and fight! After saying that, he quickly fired a few shots and turned around and ran, Han Qiao glanced at the dense army of zombies, and directly shot it with a shuttle, pulled out the magazine and smashed it, so many zombies, they would definitely be able to hit one or two. Then pull Zhou Wen and run, the three of them took over the retreat formation, and slowly retreated to the passage of the first fierce battle, because this passage is relatively narrow, only five people can come together, so so many zombie armies were immediately blocked, and they could only slowly pour into this passage, Han Qiao and the two of them were at the other end of the channel, frantically shooting point-of-point, Zhou Wen was loading the two people at this time, there were too many zombies, although the two of them were trying to shoot, Still can't resist the pace of the zombies' attack "Mystery, we're coming out right away, cover shooting!" Thousands of zombies! He didn't know that he could hear the top of the mystery, and shouted into the headset, "Hold on!" Hold on! The mystery woke up Chen Bin next to him and raced the anti-materiel sniper rifle "Something happened to them, aim at the ammunition box at that gate, and you shoot again when I let you shoot!" After saying that, the mystery pulled his M200, deliberately replaced it with a steel-core armor-piercing bullet, and stared closely at the gate.

After a while, the mystery and Chen Bin's sniper mirror appeared in the figures of the three people who defended the sky, "Run over directly!" I'm covering! The mystery shouted at the headset, and then saw the three people turn around, shoot the bullets in the gun directly, and then run directly towards the building where the mystery them, "poof, poof......" The mystery began in the dormitory, and no one noticed that the corner of the mystery's mouth gradually flowed blood, blood flowed out from the corner of the mouth, passed through the air, and dripped on the hand of the mystery who kept pulling the trigger, and the blood penetrated into it again. As the blood continued to penetrate, the gunshot, which was originally "poof, poof, poof", gradually turned into a continuous sound of "poof, poof". No one found out about this. "Shoot! Now is the time! After carrying out a crazy blockade, the mystery issued an order to Chen Bin next to him. But Chen Bin didn't shoot for a long time, because he didn't dare! "You're shooting! Or they're going to die! After the mystery was finished, a mouthful of blood spurted out, because he looked at Chen Bin and said, the distance between the two people was close, so Chen Bin was sprayed all over the face, and Chen Bin, who was startled, instinctively pulled the trigger, "boom" The unique sound of the aw50 anti-equipment sniper rifle sounded, but randomly, there was a big explosion in the ammunition depot, and the remaining ordinary ammunition exploded directly, and the parents who bombed the zombie army inside couldn't recognize it, and our Chen Bin classmates were stunned by the aw50 anti-equipment sniper, The blood sprayed on his face gradually penetrated through his skin, and when the three of them ran to Chen Bin and them, there was not a trace of blood on the body and face of the mystery and Chen Bin, but both of them were unconscious.
