Zhao Gang picked up a strong flashlight and shone it through the big hole in the door, and through the smoke he vaguely saw that there was no trace of a monster behind the hole.

"Don't be careless, since they dare to come, they will definitely not retreat so easily." Zhao Gang said coldly.

"What now?" The bear's throat is a little dry.

Zhao Gang licked his lips and burst out two words: "Hold on!" ”

"Hold on?" Fat Dong and Bear asked differently.

"Yes, in the current situation, it is best to stick to it here. The divisional headquarters at the front must have sensed the loss of our contact, and it won't be long before reinforcements arrive. Rushing out recklessly is only a dead end! Zhao Gang said.

Will the front-line divisions really send reinforcements for an observation post 1108? Even if someone comes, will they be able to save them? Bear and Fat Dong are not completely without doubts in their hearts, but they have always been convinced of Zhao Gang and let them follow his instructions as always.

"The next wave of attacks should be coming soon, so be careful." Zhao Gang was unwilling to abandon the No. 1108 Observatory no matter what, and in the end he just coldly left this sentence.

"The next wave?" While everyone was still thinking about what kind of offensive the next wave would be, the next wave of attacks was already coming as scheduled.

......What emerged from the broken doorway was not the strange and majestic mysterious monster, but a group of black-winged bats that fluttered under black pressure.

"Bang bang!" The bear immediately made a decision and fired several shots in succession. In the powerful barrage of ******, countless bats turned into blood and flesh and fell one after another. But even so, it still can't resist the large number of mutant bats breaking into the base.

These bats are also the product of the cell infestation of alien monsters at the beginning of the Doomsday, and they do not have great combat power like corpse beetles, but they have unparalleled agility and toxin-carrying teeth. It's just that this mutant bat is the same as a corpse beetle. It still retains the habits of some of the infected species and does not have a great desire to attack. If it weren't for the command of the "superior person" behind him, he would not have appeared in this underground base so unreasonably.

"Get out of the way." Zhao Gang roared, and in the face of the overwhelming bats, he turned out a flamethrower set hidden at the bottom of the weapon cabinet at the beginning of his discovery. Thanks to Zhao Gang's meticulous maintenance on weekdays, this extremely dangerous weapon did not drop its chain at a critical moment. Raging flames erupted, destroying large swaths of mutant bats with the force of wind and clouds, and many bats that did not burn to ashes in the first place fell to the ground with golden-red flames. With a half-cooked body, he fluttered his wings on the ground dyingly.

Zhao Gang skillfully used the weaker fire to burn the bats that broke into the base, and then increased the firepower to shoot the huge pillar of fire directly out of the deadly doorway, eager to burn the "Grim Reaper" who had been standing outside the door and peeping coldly into ashes.

"Boss, this guy is having fun, and he also lends me to play!" Fat Dong saw that Zhao Gang was holding the muzzle of a flamethrower, and bursts of flames emitted like cirrus, which was so majestic that it looked like a terminator possessed by an old movie, and couldn't help but say.

"the fart! See if you have been bitten by a bat and get your own antivenom. When are you still playing! Zhao Gang sprayed the flamethrower until it was dumb, and then he first pulled out a syringe from the pocket of his combat uniform, bit open the envelope with his teeth, skillfully pierced into his other arm, and injected himself with antivenom with one hand.

There was a panic just now, countless mutant bats attacked, and almost everyone was left with sharp teeth bite marks, fortunately, the poison of this bat is extremely slight, as long as it does not enter the human body in large quantities, plus timely injection of antivenom, it can be safe. This antivenom, which is standard for combatants, is carried in the pocket of the combat uniform. At this time, this group of recruits who went to the battlefield for the first time looked at Zhao Gang and gave themselves a shot.

"Boss, be careful!" After Fat Dong injected himself, he looked up and saw Ma Kai raising a gun at Zhao Gang with a frightened face, thinking: "It's not good, this kid has been beaten hard, this will be dead, I want to collapse the boss!" "I just wanted a fat pig to pounce and pounce on Zhao Gang. A gunshot was heard, and a black shadow behind Zhao Gang fell to the ground.

Everyone turned their heads in surprise to see a human-shaped monster twisting in pain on the ground. The monster was about the size of an adult, and had brains and limbs, but it had a long tail, a hideous face, and green fangs; The whole body is covered with delicate scales, and the color is gray, as if it is covered with a layer of snake skin, and it is really not easy to find it if it is hidden in the dark. "Stinky boy is still a little useful!" Zhao Gang grinned at Ma Kai. Ma Kai also smiled at him in response awkwardly, obviously he hadn't forgotten what Zhao Gang had beaten just now, but Zhao Gang didn't seem to care, in his opinion, it was natural for veterans to teach recruits a lesson, isn't there an old saying, veterans beat recruits, and the more they beat, the more they get kissed. What's more, Ma Kai, this kid really should fight.

"Stalker!" Zhao Gang gasped, he turned his head to look at the protective door that had been broken, only to see a few gray shadows flash away, sliding like a spirit snake into the dark corner of the base. At this time, the main power supply of Observatory 1108 was cut off, and the huge underground base was lit by several emergency lights, which became more and more dim.

Like the corpse beetle and the black-winged bat, the "Stalker Snake Man" is a monster that was infected by an alien protocellular body. Unlike the latter two, the Stalker has evolved the ability to stealth and camouflage like snakes on Earth, and has a human-like body structure, with a certain assassination ability. Although they are only the lowest level of combat power among alien monsters, their sturdy and compact scale armor and muscles that are much denser than humans make it difficult for even bullets to inflict fatal damage on them. Ma Kai's life-saving shot can be regarded as a blind cat encountering a dead mouse, and it was **** luck to hit the eye of the sneaking snake man, and a shot directly broke half of his head, otherwise at most it would have left a crater on its body. Just now, when the four-man warriors at Observatory 1108 were busy dealing with the black-winged bats flying in the sky, quite a few stealthy snakemen had already taken the opportunity to burrow through the hole in the protective door.

"No, the monsters that come are more powerful than the waves, if these 'sneaking snake people' break the emergency lights, we will really become turtles in the urn, a dead end, we can only sit and wait, we must evacuate." Zhao Gang, who has rich experience in the battlefield, briefly analyzed the situation in front of him, although he was extremely unwilling to abandon the 1108 observation station that he had painstakingly managed, but for the safety of his three subordinates, he could only make the decision to abandon the underground base and evacuate quickly.

"Let's go! You guys withdraw first, withdraw from the safe passage at the back, no matter what's outside, give me a bloody way to the garage, and when you get to the garage, you immediately drive to the division headquarters for help, and I'll stay behind! ”

"Boss! Let's go together! "That's right! We will not leave you alone, boss! Fat Dong and Bear said in unison.

"Get out! Don't even listen to Lao Tzu's orders? Can't do it the other way around? Zhao Gang roared. Several emergency lights had already been broken by the cunning snake man, and a daring stalker had come up in the darkness with oil on the surface. Although these monsters have grown limbs that are no less powerful than those of humans, they still retain many of the nature of snakes. The muscles of each snakeman's abdomen are unusually developed, and they take advantage of this advantage to maintain the ability of snakes to swim silently on the ground, that is, they can silently dive into such a large number at once. However, the daring snake man was obviously not lucky enough, and before he could stretch out his sharp claws, he was swept up by the butt of a gun held by Fat Dong, who was holding an AK47, and then the bear jumped up and stepped on its two sharp claws, and the hunting knife in his hand stabbed down, piercing the monster's mouth fiercely, and then piercing the skull, nailing the whole head to the ground. Black plasma erupted, and the bear pinched the handle of the knife a few times to make sure that its entire brain tissue had been destroyed before pulling out the hunting knife. Filthy blood sprayed on his face, which had been twisted by excessive exertion, and it looked even more hideous.

Although this series of cooperation cannot be said to be wonderful, it can also be said to leave no gaps, which also shows that although the three veterans of Observatory 1108 are usually sloppy and slippery, they are also unambiguous at critical moments, after all, in this era, they can't survive anywhere without two brushes in their hands.

Killing only one stealth snake man obviously won't scare off the rest of the monsters. There are many shadows in the darkness, and the unique "hiss" sound of the snake people is constantly approaching. The voice was obscene and blatant, as if the serpent was making fun of the desperate rats.

"Let's go! Don't go yet! Want to die together? Zhao Gang yelled with red eyes.

"If the boss doesn't go, we won't go." Fat Dong and Bear cried at the same time again.

"Boss......" Ma Kai couldn't stand it anymore, and just wanted to speak, but heard Zhao Gang interrupt rudely, "******, you rabbit cub also want to rebel?" Did you think I didn't beat you hard enough just now? , I beg you little ancestors, it's enough for me to be buried alone at No. 1108! You all give me life! ”

Cornered, Zhao Gang looked like a mad tiger, holding a machine gun to strafe and force back the snake man, while roaring at Ma Kai. Ma Kai shrank his neck in fright, but he still had the courage to say, "Boss...... Don't we still have that thing...... Stuff...... Is it? Why don't you use it? As he spoke, he pointed to the storage room behind him where the weapons cabinet had been kept.

"You're still rambling...... What the...... Well? That thing? Zhao Gang was stunned for a moment, and then reacted, "Yes, our No. 1108 Observatory still has the heirloom at the bottom of the box......
