January 4, 438 A.D

Opening the simple door on the twenty-first floor, the two dogs walked down violently, and the two mechanical dogs provided lighting behind them, one left and one right, and the reason why they were not allowed to go ahead was because if cockroaches appeared, the scattered bullets of the two dogs would accidentally injure the mechanical dogs.

There are obviously more mutant cockroaches encountered along the way than upstairs, basically there will be four or five on each floor, and there will be more open doors when encountering soldiers, and the more you go down, the more frequent the cockroaches appear.

Ergou even saw cockroach eggs on the corpse in a barn, and the light of the tactical flashlight hit it, and it could be clearly seen that countless translucent larvae inside were constantly wriggling. It's so disgusting, Ergou doesn't care whether the fire will burn down the facilities in the warehouse, and the overall fire sprinkler system of the building on the east side of the base fails, but fortunately, the base buildings are all fireproof materials, not all sprayed with gasoline, and the fire can't happen.

Two hours later, Ergou swept to the forty-first floor, and it was the warehouse floor, looking at the structural diagram Ergou knew that this warehouse had underground tunnels in the east, west, south, and north directions under construction, and he didn't know where it was connected.

With the material on the back of the mechanical dog, a simple door was made, and then the warehouse door was opened, and the inspection was still piled up, and the difference between this warehouse was that the construction machinery and tunnel building materials were the majority, because the tunnel needed to be excavated, and the four passages were extended outward for more than 20 kilometers.

Ergou did not go to explore one by one, the time is limited and the space is too large, no abnormality was found in the warehouse, he found the mechanical dog container on this floor, activated four attack dogs, four reconnaissance dogs, let them patrol the warehouse and explore the tunnel, they will automatically go to the general energy station to charge when the power is used up, the mechanical dog will pass the information to the BB bracelet of the second dog in real time, and the exploration of the tunnel can be safely handed over to the mechanical dog.

Fortunately, the cockroach activity area is limited to the fire escape, and there is no sign of cockroach activity in the warehouse, otherwise the loss of goods can be imagined.

After the warehouse exploration was completed, due to the first experience, the second dog was prepared this time, and there was no extraordinary excitement of the wealth fan, and after a simple inspection of the warehouse on this floor, he continued to go underground.

Ergou is going to complete the cleaning of the entire fire staircase today.

The more cockroaches go down, the body of the mechanical dog is made of metal, and if it touches the cockroach body fluid, it will corrode and affect its life, so the second dog is very careful.

At least 6-8 cockroaches are encountered on each floor, and the density is so large that the two dogs feel the need to kill them.

Thinking about choosing a suitable location, when I walked to the corner of the stairs on the minus forty-eighth floor. Ergou stopped, and stood cautiously with his back against the corner with his weapon in hand. He vaguely felt that there were a lot of cockroaches below, because of the sound made by the cockroaches.

After a pause, Ergou took out a signal flare and loaded it on the pistol, poked his head out and hit the signal flare at the corner of the lower stairs, during which Ergou observed from time to time, and it didn't take long for swarms of cockroaches to begin to gather on the lower stairs.

"Lao Tzu fought with you! Yes! Yes! "The whole body was full of ammunition to arm the two dogs, shouting to cheer himself up and flash out of the corner of the stairs, the shotgun in his hand pointed at the bottom of the stairs, and began to shoot wildly, "Click~Boom, Click~Boom" It seems that it should be said that the bombardment is right, with every shot of the shotgun, a large area of the cockroach swarm has been blown into soup.

The mutant cockroach swarms in the building were stimulated by the flares, and they were attacked by shotguns, and they all rushed towards the corpses of their companions in groups, rushed to the flames of the flares, and rushed to the two dogs who shot at them.

Ergou was excited, and the shotgun in his hand never stopped shooting wildly, and the bullets were swept away. The cockroach colony is not decreasing, but increasing. I didn't have time to change the bullets, so I picked up the spare shotgun behind my back and continued to shoot, "Boom! Click~Boom, Click~Boom" The second gun ran out of bullets, and the third continued" Boom! Click~Boom, Click~Boom". The two dogs ruthlessly poured their ammunition, and the cockroach swarm went forward and died. When Ergou's third shotgun ran out of bullets, the cockroach swarm still kept gathering.

The four shotguns on his body needed to be left for self-defense, and Ergou decisively threw away two grenades and hid back at the corner of the stairs. In order to expand the anti-personnel grenade was not dropped in a position, Ergou tried to throw it on the wall at the corner of the staircase, so that the grenade could bounce to the lower floor, "Boom ~ Boom" two grenades in a row exploded in a relatively confined space, even if it was separated by two flights of stairs, the shock wave also made Ergou feel a liver tremor, and a huge sound echoed in the corridor, around Ergou covered his ears, and he was stunned for a long time, shook his head, and quickly loaded the shotgun. During the period, he threw another grenade, and after the explosion, he flashed out violently and continued to bombard and sweep away the cockroaches that had slipped through the net.

At this moment, the second dog found a guy twice as big as the average cockroach appeared in the corner downstairs, it seemed to be attracted by the explosion of the grenade, this guy is more than a meter long and almost the same as the mechanical dog behind him, and the chest and abdomen also glow with a strange fluorescence, this is the boss of the radiation cockroach, how dare the second dog slack off, continuous shotgun waiting, because of the distance of a staircase, not close shooting, not the maximum lethality of the shotgun, full six shots, this big guy was exploded. I wanted to fly up and attack Ergou several times in the middle, but I was directly hit by Ergou's crazy firepower and exploded. I have to say that this kind of battle is still very cool, and there is no doubt that Ergou enjoys the process. The grenades in turn waited for the shotgun bombardment, and soon the follow-up troops of the cockroaches were significantly reduced, and at this time, Ergou estimated that he had killed no less than a hundred radiation cockroaches.

Are these cockroach limbs valuable, Ergou thought, there were too many corpses, almost blocking the corridor, and Ergou couldn't get past the mechanical dog, let alone the mechanical dog, so he could only set fire to the moment. Decidelessly threw three incendiary bombs and let the cockroach corpses burn.

Ergou naturally will not be idle, and went to the door of the forty-sixth floor of the barracks leading to the elevator warehouse, and sure enough, it is still not passable, and if it is not passed, it will be repaired, which is not a matter for the little brother of the engineering team. Ergou did not lack any materials, and quickly repaired the passages of each warehouse in the elevator hall on the forty-sixth floor, and explored each warehouse. All the intact personnel survived, except for the east side of the barnage, the lower level of the base, the number of researchers and engineers increased, and the corresponding barn decreased, and it was already one o'clock in the afternoon after all this was done.

The fire on the fire escape is still burning, let's have some lunch in your spare time, the second dog is hungry.

He sat in the corridor that he had just repaired in the elevator hall, his legs hanging down from the corridor, and the dark abyss below, took out the huge sandwich that Zuo Wei had prepared for him with full filling, and ate it, um~ Every bite is full of happiness. What is this chick doing? I don't see her for a while, and I miss her a little.

"Calling Zovi! What are you doing? Ergou was eating and chatting, his dangling calves were still kicking around, and the engineering lights behind him hit Ergou's body and formed a huge shadow on the opposite wall.

"What about you at the top outpost, did you miss me?" Ergou's call made Zovi happy:

"Why don't you want to call? I'm minus forty-six, do you mean our dad is minus forty-eight? Looks like I can see the door now. The second dog said and took a big bite of the filling-filled sandwich.

"Whew~ Yes!" Zuo Wei obviously increased her breathing: "After so many years, I hope there will be no accidents!" ”

"Don't worry, there will be no problem with the visual inspection of the room door in good condition. It's cold outside, isn't it? Don't freeze to death. Recon missions can be given to the Robot Dog. "Ergou is really distressed Zuowei:

"Well, I've got an extra combat uniform. There are more drones than I estimated. I'll have to keep an eye on it, and be careful over there, I've seen the corpse of a radiation cockroach, it's still quite dangerous. The two men cared for each other:

"Well, wait for my good news in the evening, and the call will end." Ergou ended the call, took out the last sandwich in the lunch box, and prepared a few bites to end lunch, but accidentally dropped the lunch box belt.

Ergou subconsciously looked down, and his left hand quickly picked up the engineering lamp behind him to shine downward, and at this time, the bento box fell to the bottom of the pit. It is located on the minus forty-six floors, and there are sixteen floors from the bottom sixty-two floors, each of which is five meters high, and there are more than eighty meters deep to the surface of the water. It's so deep, Ergou is sighing, vaguely seeing that there seems to be something underwater. He squinted his eyes to see what was underwater, and a large black figure burst out of the water and swallowed the bento box with its mouth open, before diving into the water and quickly vanishing.

"I wiped it, what the hell, my love lunch box was eaten!" Ergou shuddered, and instantly retracted his dangling calf, abyssal troll? Everything happened so fast that Ergou didn't even see what kind of creature it was, it seemed to be a fish, but it was too big. Hurry up and get out of here, he is afraid that if he falls, he will be swallowed by the huge black shadow in the water!

Ergou returned to the fire ladder, the corpse of the radiation cockroach was still burning with thick smoke billowing from the fire, the smoke choked him squinted, and quickly found a fire hydrant of the fire ladder, tried to have water, he was too lazy to connect the pipe, and directly opened the fire hydrant in this fire ladder, and a large amount of water gushed out instantly, flowing to the lower floor of the stairs, and the fire was quickly extinguished. The water from the fire hydrant washed the ground, and the remaining cockroach carcasses were washed away. After more than 20 minutes of water, the corridor was cleaned up, and Ergou turned off the fire hydrant and began to step on the soaked stairs to investigate down.

Forty-eight floors are secure, and forty-nine floors are cleared. Fifty layers of security. Ergou no longer went down, and once again let the mechanical dog send a large number of building materials, and directly built a simple door on the 50th floor, because he wanted to go back to explore the 48th floor, the engineering team brother Ergou opened the East Bingcang with a familiar car, entered the elevator hall, and repaired the elevator hall corridor.

The little brother and the second dog on the construction site did the work of tinkering, which was really smooth. A large hallway leads directly to the westernmost side of this level, and the nameplate on the door reads Base One. The person inside is the future father-in-law that Ergou is looking forward to, King Stan.
