I don’t know if it was intentional. In the entire school, the power supply of most electrical equipment except the corridor induction lights was disconnected, which made it more difficult for all players to move.

If you use a flashlight, although you can illuminate the nearby environment, it will also expose your position. In the dark, the bright flashlight is simply the best target. When you use a flashlight, you almost engrave the four big words "Come and beat me" on your forehead.

However, if you don’t use flashlight, it will be quite embarrassing.

Gu Bin discovered that there was a crescent moon hanging in the sky outside, and the curve made people feel cold. The cold light shone through the windows in the classrooms of several experimental buildings, which looked quite strange.

If you didn't know that this is just a school and not a scene in a horror movie, Gu Bin would probably be trembling with his legs now.

He carefully opened the podium drawer of the classroom and illuminated it with a flashlight twice. He found that except for a piece of ragged rag, there was only a stained key, and all that was left was just some garbage. As for the cabinet behind the classroom, there were some bottles and jars left with labels on it. Now Gu Bin is in a chemistry laboratory, located on the fourth floor of the laboratory, Xu Qing squatted beside a desk, trying to remove two iron bars and steel pipes to use as spare weapons.

He took the flashlight and shook it towards Xu Qing. Gu Bin shook his head and indicated that he had not found anything useful, and then pointed to the medicine cabinet behind him.

Xu Qing nodded and made a key move.

Gu Bin picked up the rusty key, shook it twice, and then walked towards the back of the classroom.

The classroom where the two were located was located on the fourth floor of the laboratory building. Most of the classrooms here were closed, and only a few were open. After looking at the two classrooms a little, Gu Bin knew that there might not be any useful things from these classrooms. However, this did not stop them. The ventilation window above the side of this classroom was open, which could fully support one person to pass. With the help of the hemp rope, the two people supported each other and successfully got in.

The sliding grooves of the glass cabinet were obviously a little rusted, and Gubin moved them away very carefully, making as little noise as possible.

Most of the medicines are still well preserved, and there are some experimental equipment next to them. After looking at them, they were mostly glass products. Gu Bin gently took two beakers and placed aside, and also took a glass rod, two test tubes and a measuring cylinder.

He felt a little funny. In such a serious environment, he seemed to be a student who secretly ran into the laboratory to do experiments. He was a liberal arts student and had never caught a cold about physics and chemistry. Gu Bin still remembers that when he was in junior high school, he had to pay a fine once he entered the laboratory. The reason was very simple. He could put in two sets of experimental equipment that he had damaged.

A crisp sound came from there. Xu Qing worked hard for most of the day and finally removed an iron bar from a broken test bench. It looked very fierce and longer than an adult's forearm. It was originally a horizontal bar under the table, and it was a little rusty, with the edges and corners rolled up. This was a natural blade and an absolute weapon for fighting.

Gu Bin handed the flashlight in his hand to Xu Qing who was walking over, and asked him to help him take it. He freed his hands and took out all the medicines he could take out from the cabinet in two seconds and placed two rows on the next lab table.

"Balt, hydrochloric acid..." Gu Bin racked his brains to recall various chemicals that he still had an impression of. After all, he had very little involvement in this area. He could think of only a few chemicals with powerful lethality, and this place was just a school, so he didn't expect to find anything that could be extremely lethality here.

"It seems that I will make up for some American drama when I go back." Gu Bin suddenly remembered a criminal American drama that was seriously related to chemistry. He pulled the corners of his mouth, picked up a bottle of potion, and looked at the label.

Gu Bin is still very impressed with the things like concentrated sulfuric acid. One of his clothes was stained with a little concentrated sulfuric acid during class, and a hole was burned out. If this kind of thing touches the wound or skin, the effect should be terrible.

Xu Qing also had some understanding of this kind of thing. The two of them picked out a few things in a few seconds and were very lucky. They also found half a box of matches, a lighter and a half pack of cigarettes from the drawer of a laboratory bench. This made Xu Qing ecstatic and could see that he was an old smoker. This long life in prison was simply torture for someone like him who was smoking-free.

Rationality defeated the urge to smoke immediately. Xu Qing swallowed two saliva and wanted to stuff the cigarette. However, after thinking about it, he took out the outermost cigarette, took it apart, took out the tobacco and put it in his mouth and chewed it slowly.

Gu Bin shook his head. Although he had smoked cigarettes, he had no dependent on this thing. He went back to the podium and took the rag, teared it into three pieces along the crack, and wrapped several bottles separately to avoid making a sound when placed in the package.

"Bang!"

Gu Bin, who was loading medicine, suddenly became stunned. He turned his head to look at Xu Qing and found that he was leaning against the table and chewing tobacco with an intoxicated look on his face. At this time, he also opened his eyes wide. Seeing Gu Bin looking at him, he immediately made a gesture outside, indicating that someone outside was there.

Gu Bin made a quick decision and turned off the flashlight. Fortunately, the flashlight had the smallest aperture at the beginning, so the entire classroom would not be lit.

The sound of footsteps came from the entrance of the stairs. Originally, the sound was not very loud. It could be heard that the person outside should have deliberately suppressed his movements, but it was obviously not very successful. The man walked very quickly and was almost running away.

Xu Qing picked up the steel bar, picked up a piece of rag on the table and wrapped it at the bottom, and quickly came to the back door, touched the door lock twice with his hand, and at the same time he made a crossbow-heading position towards Gu Bin who was looking at him.

Gu Bin sighed inwardly, wondering whether Xu Qing's behavior was out of his own confidence or because he trusted him very much. In short, Gu Bin inexplicably felt that he was being looked down upon, and there was nothing he could do. He knew that his previous actions were enough to make Xu Qing label him as "powerless".

He took a crossbow arrow and pressed the top plate behind Anger against his shoulders, and made a pretty standard posture, ready to face the battle.

"Pu, pu, pu..."

The footsteps were still approaching and the sound became clearer and clearer. Gu Bin felt that he could almost hear the person outside gasping through a wall.

The sound of the locked door being opened and the sound of Xu Qing breaking out of the door almost rang one after another. The man at the door never expected that someone would suddenly come out here. Xu Qing lowered his body and the steel pipe in his hand knocked directly on the man's leg. The sound of Gu Bin's body trembled.

The steel pipe passed through the man's neck hard. As soon as he was about to resist, he was hit by Xu Qing's elbow. He was beaten to the spot and was dragged into the classroom by his throat. Gu Bin was prepared and directly aimed the folded crossbow at the man's chest.

The man's face was blurred and his body had not been processed.

Gu Bin stepped forward and snatched the thing that the man was holding on his own, throwing it aside. As soon as he got it, his heart chilled. It was actually a pistol with the temperature of the man's palm on it. Someone could really get this kind of heat weapon.

Xu Qing obviously saw the pistol and whispered. His actions just now were also caught off guard. Although it is difficult for ordinary people to control firearms, if they are shot in chaos, they may be fatal.

The weapon was taken away, and the man seemed to have been appointed, panting and slid there motionless.

Xu Qing took a few breaths, lifted the steel pipe, knocked it down hard, and hit the player's knee on the other leg with a click. The cruelty of the movement made Gu Bin unable to stop sucking the cold air.

The severe pain made him scream. Xu Qing couldn't give him this opportunity, and the steel pipe pressed horizontally into his mouth. The man could only hum there while whispering in pain.

“Outside, luggage.”

Xu Qing stood up, walked towards the laboratory bench, pointed out the door, and signaled Gu Bin to take the bag in.

Gu Bin nodded, turned around and walked out of the door. After confirming that there was no one outside, he quickly walked towards the bag, picked it up and the flashlight beside him, and quickly returned to the classroom.

Xu Qing was skillfully checking the pistol. When Gu Bin came back, he raised his hand and said, "Makarov pistol, such an old style, is equipped with a muffler." As he said, he pulled out the magazine and took a look, and said, "This guy fired the gun, and used four bullets."

Gu Bin put the bag on the laboratory bench, unzipped the zipper, took out all the food and water. The water was boiled and half a bottle of it had been drunk, and the compressed biscuits had not been moved.

Xu Qing took the water bottle, took a small sip, and then handed it to Gu Bin.

Gu Bin actually has a slight obsession with cleanliness, but this habit has been almost done in prison life. At this time, he took a small sip to moisten his throat without any mind.

He lowered his head and began to count the supplies, touched out everything, while Xu Qing came to the side of the player who was still rolling around, and pressed him down and began to plunder his pants pocket. Gu Bin guessed that he might be planning to consume all of this guy's bullets to prevent future troubles.

"Map, ink pen..." Gu Bin arranged these things in a row next to him, gritted his teeth and used his pen to destroy the map, and then locked out the battery in the flashlight.

"Wait, it seems like something is missing?"

Gu Bin inspected these items again, and then suddenly remembered something. His hair exploded and he quickly turned around to look. The moment he turned around, a dazzling fire exploded in front of Gu Bin, and the dangerous temperature spread rapidly in the air. Mobile phone users should visit http://m.piaotian.net
