The administrative building has five floors, and the elevator equipped with has been powered off. It should be because of the actions that Gu Bin and his two intentions taken after discovering it. There was no stopping too much. Xu Qing opened the way and Gu Bin followed closely. They didn't have much time to waste. Once the enemy caught up, those who waited for the two would be destined to be attacked from both sides. Maybe the little pervert who said that Xu Qing could run around with a machine gun would come over. If that was the case, they could close their eyes and wait to die.

Xu Qing gestured at Gu Bin and pointed to the surveillance cameras hanging at the corner of the ceiling. Gu Bin knew that this bastard was afraid that he would not dare to shoot at the enemy at a critical moment, but Gu Bin was happy to accept that he really had such a hidden danger. It would be better if he was far away. If he was close, he wouldn't be able to do it.

The two of them climbed up the stairs, but the surveillance room was already in chaos. The young man with Shamatt hairstyle had a blue face and watched Gu Bin compete with his middle finger towards the camera, then raised his gun and blew the camera.

A grenade was stuffed to Gu Bin by Xu Qing, and Xu Qing asked him to act according to the opportunity. Gu Bin looked carefully at the stairs of the administrative building. It was probably a steel and concrete structure. A grenade alone might not cause any serious consequences, but it is still very effective to use it to stop the pursuers at critical moments.

Xu Qing suddenly stopped when he turned the corner of the second floor, and his body flashed forward very quickly. He raised his gun and fired twice before retracting his body. Gu Bin only heard a muffled sound, followed by a series of bullets flying over and hit the floor in front of them, and fragments of ceramic tiles splashed everywhere.

Gu Bin smiled and took out his hand in his backpack. Two bottles of chemicals were already in his hand. He waved his arm and swung them hard. The original two bottles, along with the two bottles copied with skills, were thrown up, as if they had hit the wall, and the glass was all broken, and followed by a large amount of smoke and a pungent smell.

The gas produced by this reaction not only covers the field of view, but is also very pungent. Gu Bin doesn't believe that these people can still shoot well under such circumstances.

Xu Qing, who was already prepared, rolled out skillfully, swept out a shuttle, then rushed forward, covered his mouth and nose and rushed into the thick fog.

Gu Bin didn't have the ability and ran upright with his breath. There were countless people lying on the ground, and Xu Qing did not hold back. In his eyes, these underage children holding guns were no different from adults. Since they picked up something that was not consistent with their age and did something that was not consistent with their identity, they had to take corresponding responsibilities, which was in line with the principle of equivalent exchange.

Try to keep his mental condition stable and not think too much. Gu Bin rushed through the thick smoke in two steps at a time and poured several sips of water into his mouth. The burden on his body when using his skills is not a joke. He felt a burst of thirst and powerlessness after just copying two bottles of potions.

He must maintain a certain physiological state. Xu Qing handed over the grenade to Gu Bin based on his special skill. However, Gu Bin himself didn't know how much physical energy it would consume to copy a grenade, and maybe it would drain all his physical energy.

As Gu Bin thought before, in order to retaliate against the two, there were very few people left in the administrative building. After getting rid of more than a dozen people, the shooting skills were not good, and after only being considered a scattered soldier, there were few people who could resist them.

The guns in their hands were replaced with pistols, and all the previous rifles and bullets were shot out. The two had to pick up the pistols from the ground to use them. When they arrived on the fourth floor, a considerable commotion finally came from the bottom of the building. Gu Bin just stretched his head and took a look, and a round of bullets flew up, which scared him so much that he quickly retracted his head.

He vaguely saw a burly figure running on the stairs, and the loud footsteps were not hidden at all. Gu Bin gritted his teeth and kicked Xu Qing, asking him to go to the fifth floor quickly, and took out a grenade from his pocket.

Seeing Gu Bin's appearance, Xu Qing had nothing to say. He immediately ran up like a mad dog. He wanted to tell Gu Bin that the big guy he met was really a monster, but there was not much time left for them now, so he could only say that he had his destiny.

Seeing Xu Qing leaving with two pistols, Gu Bin started to use "memory display" without saying a word. The originally empty left hand flashed, and a grenade that was consistent with the "sample" had emerged out of thin air. Immediately afterwards, Gu Bin's body swayed.

If the energy consumed by replicating chemicals and replicating paring knives was 1 unit, then the current replicating grenade consumed at least three or even five times the former. After this grenade was replicated, unlike the previous feeling of "spirit being pulled away", Gu Bin's current feeling is that his flesh and blood, even bones were pulled away, and he was unable to stand firmly and his strength disappeared, and he also felt an unbearable sense of pain, just like a bug gnawing at his bones.

Not only that, the moment the grenade was copied, Gu Bin felt his stomach churning, not pain, but the feeling of emptiness. To put it more than exaggeratedly, it was the chest that felt the presence of his back, so hungry that his mouth became extremely dry at the first moment.

Resisting the discomfort, Gu Bin threw the grenade down the stairs, letting it roll to the corner, and continued to copy it himself.

...

The fifth floor was silent, which made Xu Qing very uneasy. He shot two shots to the surveillance camera above his head. He carefully poked his head, but still did not see anyone.

The door of the monitoring room was open, as if we were welcoming visitors, while the doors of other offices were locked. According to Gu Bin's previous inference, the young army paid a certain price to capture the school, and they must have chosen a school with a small number of people to take action, which would lead to them being unable to open most of the room doors, because they could not spend a lot of energy to smash these doors one by one. Only a few could open them, so there was no need to be too much warning to those closed offices.

Walking slowly to the door of the monitoring room, Xu Qing saw a familiar face at a glance. No, it should be said to be a familiar mask. The Sun Wukong mask, which brought strong shock but was extremely rough to everyone at the beginning of the game, was sitting on the stool very quietly, looking at him with his hands behind his back.

If it were a guy like Gu Bin, he would probably say a few nonsense, but unfortunately, this kind of thing was not Xu Qing's strength, so when he saw this person, he raised his hand and fired.

The pistol bullets rotated in the air, easily breaking the simple plastic mask, tearing the skin on the forehead, drilling into the head, and blood and brain matter flowing freely.

Still worried, Xu Qing shot the man two more times in the chest without changing his face, and then he squatted down and lifted his mask.

The moment the mask was lifted, he was stunned. This face belonged to an adult and did not belong to any teenager. Then, he heard a system announcement that made him creepy.

"You killed an enemy and earned a little points, and now you have 6 points, ranking first."

The body of the player who was used as a substitute disappeared from the spot, leaving only a pool of dirty blood.

With the experience and instinct he developed over the years, when he noticed something was wrong, Xu Qing rushed out to the side, rolled around on the ground, raised his hand and shot behind him.

Two different gunfires sounded at the same time, and Xu Qing felt that his legs were itchy, and then there was a piercing pain. Before he could turn his head, he was hit hard on the back of his head.

Because of insufficient strength, Xu Qing was not stunned directly. Instead, he stretched out his hand with a fierce force, grabbed the wrist of the sneak attacker, twisted it hard, threw him aside, and twisted it with the momentum to remove the gun in his hand.

The man seemed to not care about the weapons in his hand at all. While Xu Qing grabbed the gun, he kicked him hard on the waist, and took advantage of his condescending position and kicked him to the ground.

Xu Qing seemed to have known this man would be like this. He pulled out another pistol when he fell to the ground, pulled the trigger continuously in the direction of the visitor, and shot out all the remaining bullets in the magazine, without exception, all hitting the man's body.

The continuous muffled sound made him feel cold. No bullet successfully caused damage to the sneak attacker, which at most caused him to take a few steps back.

"Body vest..."

A word floated out of Xu Qing's mind, and he watched the young man with a ferocious face and with the release of Shamatt pulled out a pistol from his waist. Xu Qing's scalp exploded, roared, activated his skills, and used the terrifying acceleration to pounce. He knew that he had to work hard like this, otherwise all efforts would return to the starting point, so even if he could be beaten into a sieve, he could only rush up.

"boom!"

Continuous vibrations sounded throughout the building, and the violent tremors caused everyone who could stand in the building to fall to the ground. The young man holding a pistol was no exception. He was messed up by the sudden vibration. The pistol tilted and before he could pull the trigger, Xu Qing threw himself to the ground.

During the crazy fight, the pistol was thrown to some extent. Xu Qing, covered in blood, was like a crazy beast, smashing it down one by one, and the young man also roared and made a counterattack. In just over a dozen seconds, the two of them had already had blood on their faces as if they had opened a soy sauce shop. Both of them had reached the point where they were exhausted. At this time, they were fighting with a will, and there was no way to speak of it.

"Pu"

A weak figure appeared at the door. The two people in the fight looked at each other and saw a haggard young man with a grim face and raised his hand with a smile, pointing the pistol in his hand at the head with Shamatt's hairstyle.

Gu Bin staggered two steps and pushed the pistol to the boy's forehead.

The system announcement came late, the plot of the entire copy has been cracked, and the copy will end in ten seconds.
Chapter completed!
