"Enough! I've had enough, don't fight again. Zhao Gang glared at Fat Dong and said coldly. He was the first to make a move, and he was the first to stop, as the de facto leader of the 1108 Good Observatory, the situation did not allow him to be carried away by anger again.

"There is no way back now, the appearance of the corpse beetle is by no means accidental, and we must not take chances, those alien monsters have always been to kill our humans." Zhao Gang reluctantly lit a cigarette and took a hard puff, forcibly suppressing the panic in his heart and forcing himself to calm down. "If you want to survive, you have to prepare for the worst, and Observatory 1108 is really not safe. It's a pity that the garage is outside the security gate, and the video surveillance is broken, so I don't know what the situation is there......"

"Boss! It's not right, you see! The bear who had always been calm suddenly exclaimed, pointing to the power line cover that had been pried open by Zhao Gang just now. Zhao Gang heard the sound and looked over, only to see more than a dozen corpse beetles the size of rats crawling out of it, rubbing their sharp teeth unscrupulously, making a bone-sour sound, and rushing towards them.

"Oops, the smell of blood on the other end of the first end drew them in!" Zhao Gang scolded secretly, it was really careless, although the teeth of the corpse beetle were sharp, but with only one person, it was impossible to bite off the cables of the entire 1108 observation station anyway, and he should have thought that there was a large group behind.

"! The deception is too great, even this group of little insects dare to show off their might! Lao Tzu trampled you to death! "The bear couldn't bear it anymore, so he raised his big foot and stepped on it violently!" Let's click, click" A few crisp sounds, and I saw a piece of black juice overflowing from under the bear's military boots.

"Don't!" Zhao just didn't have time to stop it, but he saw the bear's face change to show a huge pain, screamed, and limped up with one foot in his arms. "Fool, although this corpse beetle is not poisonous, its teeth are extremely sharp, and several layers of leather can be easily bitten open, and it is a large piece of meat at once. It hurts to death! As he spoke, he lifted the bear's feet and helped him pull out the sharp teeth left on it one by one.

"Fat Dong, go get the gauze in the medical kit, and a powerful insecticide! Fast! Hurry up. ”

"Huh!" Fat Dong led the order to run to take out the first-aid items and handed them to Zhao Gang. Zhao Gang instructed Fat Dong to continue to help the bear bandage, and he took a bottle of powerful insecticide and sprayed it fiercely at the group of corpse beetles.

Once the white mist of chemical reagent ...... touched the body of the corpse beetle, it reacted violently, emitting countless foams representing a powerful erosive effect. The corpse beetles writhed in the foam and died out in a few moments.

"Damn! Or high-tech works. The bear spat and said viciously.

"Of course it works, this is a biological agent researched by the military department at a high price, specifically used to kill this pest, but if it is used to deal with the big guys, it will not be enough." Zhao Gang swept the powerful insecticide in his hand and put it on the ground.

The bear pulled out the remains of the corpse beetle stuck to the sole of the shoe, and said hatefully: "******, it's all dead and you have to gnaw off a piece of Lao Tzu's meat!" ”

"It's too late, they're already at the door!" Zhao Gang shouted!

"Them?" What kind of monster is it? Ma Kai, who fell to the ground because of the pain in his body, also had doubts in his heart. In the face of these monsters that once cornered humanity, there is only one door away. The first thing he felt was not fear, but curiosity. An unknown force made him prop himself up and look towards the last barrier, the protective door.

"Phew! "Boom......" There was a continuous loud bang, a loud bang that shook the entire underground base as if it were hitting the heads of every member of Observatory 1108, and no one knew when the gate would be broken. The only thing that is certain is that once this gate is broken, the demons outside it will swarm in and destroy all life here.

"Boss, the guys have brought it!" Fat Dong panted and pushed a large weapon collection cabinet larger than his size (the base has wheels, so the push moves. ）

"Bang!" Zhao Gang picked up the fire axe, split the lock of the weapon collection cabinet with an axe, turned around and kicked the lid of the box, and a strong smell of nitrate oil and machinery rushed into the noses of everyone on the spot, this is a taste that makes men's blood run, even in this desperate situation, the power of this modern thermal weapon is still enough to give this group of men who were forced to death by aliens into a dose of strength.

"Observation Post 1108 itself is well defended, and it wasn't originally intended to be a large fortress to defend against a frontal attack by monsters, so it didn't store large heavy weapons...... This, Fat Dong, you take it. Zhao Gang picked up an AK47, pulled the bolt, inspected it and gave it to Fat Dong.

Fat Dong had already put on a bulletproof vest and a military hanging bag on his upper body, which was full of machine gun magazines. "Hey, it's old-fashioned, I didn't think about what was invented more than 100 years ago, and we still use it now."

Indeed, this assault rifle produced in the former Soviet Union in 1947 has been in service for more than 100 years. If the human world had not entered the era of destruction, I am afraid that it would have withdrawn from the stage of history a long time ago. It's a pity that after entering the Doom Era, mankind has lost a large area of land for survival, and the level of basic military industry has regressed significantly, although it has concentrated its strength to develop large-scale combat armor that can fight against alien monsters, but a large part of the ground conventional forces still use the old weapons left over from the era before the Doom Era.

In fact, as the world's No. 1 gun in the old era, the AK47 has always been the king of light weapons in the world before the invasion of alien beasts due to its simple and durable structure, powerful and stable firepower output, and still maintaining a very low failure rate in extreme terrain environments such as deserts and swamps. Historically, a weapon development expert has said that if it is necessary for him to go to Mars to hunt aliens and only carry one weapon, then he will not make a second choice other than the AK47.

Moreover, at the beginning of the 21st century, the development of human military science and technology has shown that high-end guided weapons and tactical guidance systems are changing with each passing day, but there is actually no substantial progress in traditional conventional thermal weapons, and the development is stagnant. The reason for this is that conventional infantry combat on the ground has long been at its limit, and even if the old and inexpensive AK47 is held by the terrorists, it is enough to compete with American GIs who are equipped with the most cutting-edge equipment worth millions of dollars.

At this moment, Fat Dong was holding a loaded AK47 with live ammunition in his hand, full of confidence, and swept away the embarrassment of being frightened, and yelled: "Damn, if this group of beasts dares to come out, Lao Tzu will see one collapse and one pair, see a pair of collapses, and kill his grandmother!" ”

"Bear! You use this! Zhao Gang took out a ****** from the weapon cabinet and threw it to the bear, "You have the strongest hand-to-hand combat ability, use this machine gun, and a hunting knife to hunt down monsters that can get close to us!" ”

Bear took the gun and nodded, then reached out and pulled out two packets of boxes (bullets).

Zhao Gang himself picked up two MP5K **********, which is as faithful as the AK47 and has a historical status that is not inferior to the AK47. Although it is inferior to the AK47 as an assault rifle at long range, and not as terrifying as the ****** at close range, it has a considerable advantage in suppressing fire at medium distances and is flexible and maneuverable. In this way, the three of them formed a group of triple three-dimensional firepower coverage in the distance, middle and near.

Zhao Gang glanced at Ma Kai, who was still huddled in the corner after being beaten by him. He took out a pistol and threw it in front of him, saying, "If there is a seed, use it to kill, and if there is no seed, use it to kill yourself." ”

Ma Kai looked at the pistol in front of him in a daze, and only reached out to hold it for a while. How long has it been? Finally, I had the opportunity to grab a real gun, and the heavy, cold metallic texture washed into the palm of my hand, and a feeling that I had never felt before came to my heart.

"Rely on the buildings in the base for defense, and don't rush out until the enemy situation is clear......," Zhao Gang ordered again.

"Bang bang bang......" Before he could finish speaking, the sound of a heavy object hitting came quickly, obviously different from the previous blow, and each blow seemed to hit the hearts of this group of men. With such a terrible sound, their poor imagination could not imagine what kind of monster was attacking the outside fiercely.

"Bang bang ......" As the impact continued, the original smooth and smooth iron door also appeared one after another shocking protrusions. The terrible protrusions became more and more frightening, and the frequency of the strikes slowed down, as if the monster outside the door had exhausted its strength and could no longer knock.

"His grandmother's, it seems that our gate is hard enough, and this group of brutes can't rush in......" Fat Dong gasped greatly and said with some joy.

As soon as the words fell, a loud "boom" was heard, and the upper part of the iron door, which had been bumpy by the monster, was suddenly blown away by the monster. This sudden upheaval frightened everyone into disarray.

There is a pair of equally black eyes peering at the human being in the dark cavern, and you can't see what is in the darkness, but the fierce light in the strange eyes makes you shudder. There was no hatred, no anger, just the ruthlessness of the predators. The determination and oppression of one species to exterminate another, those eyes just looked straight at everyone inside the door.

"Fire!" Even Zhao Gang couldn't stand to look at the monster like this, and couldn't help but hurriedly order to shoot.

The "Dangdangdang Dang ......" real gun shot was far louder than expected, the primer exploded, and the sound of the copper bullet casing being ejected by the air chamber was intertwined, completely covering the sound of mechanical transmission, which should have been crisp and pleasant.

In the midst of the deafening sound of gunfire, the monster hiding in the doorway jerked back, and the sparks of the bullets hitting the iron door only reflected a ghostly figure.

"Cease fire, change the magazine," Zhao Gang calmly ordered, before the bullets were completely exhausted, replace the new magazine, to ensure that there was room to defend against the enemy, after all, it was from the pile of dead people, Zhao Gang gradually regained his composure in the smoke of gunpowder, and commanded calmly.
