Doomsday Bunker Upgrade

Originally, the connecting passage between the main part of the refuge and the entrance part of Chen Xin was a 50-meter-long corridor, which was built to make it easier for cars parked inside the refuge to enter and exit the refuge, but in fact this The use of the tunnel is not as convenient as originally expected.

Because the length is only 50 meters, but the height difference from the entrance to the inside of the refuge is nearly 20 meters, making this section of the ramp actually very steep, driving in and out or even dragging supplies with a trolley is nothing very convenient.

However, when building the refuge at that time, Chen Xin only considered building the refuge deeper to avoid possible meteorite impacts affecting the refuge. He wanted to use the two hundred meters thick soil layer above the refuge as a protection, so he also There is not too much to entangle the details.

After all, the **** is relatively large, it is not convenient to use, not completely unusable.

But now that the system can be upgraded, Chen Xin naturally also adjusted this place, changing the originally diagonally connected corridor into two horizontal passages, using a lift to go up and down.

This is one of the reasons why Chen Xin has to wait until the city government’s supplies arrive before starting the overall upgrade of the shelter. The materials for the elevator were collected by the city government’s help. Originally, Chen Xin planned to process it himself. Up.

After the upgrade, the elevator area that appears can stop an ordinary family car. The whole is a cylindrical car with a diameter of 7 meters and a height of 3.5 meters. The bottom of the car can be rotated. This solves the problem The problem of being narrow and unable to turn around.

Sit on the elevator to the upper floor. After passing through the passage, the original preparation room is still there, but on the other side of the preparation room there is an extra material storage warehouse.

This is the adjustment made by Chen Xin due to the inconvenience of material transportation before. The material warehouse was placed on the upper level of the entrance, and only the food storage room was kept inside the refuge.

In this way, the materials can be stored directly after being transported in from the door, and there is no need to transport them further.

Anyway, for Chen Xin, the materials are almost the same everywhere. He only needs to open the system interface to use the materials, and does not need to pick them up personally.

Passing through the preparation room, it is still the passage where the heavy crossbows are placed.

Chen Xin didn't make any major changes here. After all, it was just a passage, and the attack ability of the heavy crossbow was enough.

The only thing he adjusted was the triggering method of the heavy crossbow, changing it from the original flap mechanism to infrared induction automatic shooting, and setting up a hidden mechanism to hide the entire heavy crossbow in the ceiling.

Anyone who walks through the corridor with the alarm turned on will be directly shot into the face by a heavy crossbow of 90 rounds per minute, and the power will not be worse than that of the heavy machine gun installed by Chen Xin at the gate.

As for the way to turn on the alarm, Chen Xin set it to turn on from the inside and trigger the attack through facial recognition.

That is to say, you can turn on the alarm switch from the inside to turn on the face recognition every time you come out from the inside. In this case, you can naturally enter the evacuation shelter after passing the face recognition.

However, if a stranger enters and fails to pass the face recognition, the heavy crossbow on the ceiling will be activated, and you will enjoy a dodge-fire experience.

As for exiting through the safe passage, Chen Xin didn't make any changes to the decontamination room, only upgraded the decontamination equipment inside.

The outside of the washing room is still a garage and a space that can be called a foyer or entrance.

This is an L-shaped space, with the short side connecting the gate and the washing room, while the long side is an extended garage for parking the armored RV after Chen Xinmo’s modification.

There is nothing to say about the garage and the hallway. The garage only adds vehicle maintenance functions and some car repair tools. The hallway is just an open space.

What is really worth watching is the door of the refuge.

It is still the previous lifting metal armored door, but Chen Xin changed it from homogeneous armor to multi-layer composite armor this time. The thickness has increased from 30cm to 35cm. Although the thickness has only increased by 5cm, the defense performance is equivalent to 120cm thick homogeneous metal armor.

The original double-mounted Maxim at the door was also replaced with a double-mounted 12.7mm three-barrel revolving machine gun, which is the same type as the one installed by Chen Xin on the armored car. It can still be controlled by a computer and can be automatically locked for aiming.

Of course, you can still perform hand exercises like Chen Xin did yesterday, experiencing the three thousand six hundred revolutions of one breath, the compassion that saves the world.

After inspecting the entire refuge, Chen Xin was very satisfied with the effect of the overall upgrade. In addition to the overall layout and the improvement of technology level, even the gray concrete walls of the refuge were covered with paint and metal was added. The supporting frame looks clean and tidy, spacious and bright.

Even the lighting facilities that were originally just light bulbs were replaced with LED tubes, which made the light inside the refuge a lot softer, and added the lighting control that Chen Xin has always wanted, and the lighting can be adjusted over time. , So that people inside the shelter can also feel the passing of time.

As for the observation room originally set up by Chen Xin above the gate, it has also been adjusted and upgraded this time, allowing it to evolve from a simple tree antenna room to a formal bunker, not only adding some living facilities inside, but also the observation port. A double-layer vacuum glass was also added to block the entry of cold air.

Of course, in order to retain the defense function of the observation room, the glass of the observation port can be opened to change it back to the shooting hole.

As for the vents connected to the outer wall, Chen Xin has not undergone major changes, but added a ventilation fan and an air filter inside the ventilation duct to improve the ventilation efficiency.

Back inside the refuge, Qin Lan was still sitting on the sofa and playing games. Chen Xin's previous actions seemed to have no effect on her, although the living room she was in had completely changed, and the game console was upgraded from PS4 to PS5. , Even the size of the TV has been enlarged a lot.

"Did you work?" Qin Lan watched Chen Xin pick up another handle placed aside to access the game, and pressed pause, switching the game out of the two-player mode.

Chen Xin sat down, nodded and said, "There is not much work left. As long as the materials are in place, it can be done very quickly. Now it's all done."

"It's fine when you're done, come and accompany me in a round. You lost to me last time. Now I'll give you a chance to beat me!" Qin Lan looked at Chen Xin and deliberately used the aggressive strategy against him.

Chen Xin also smiled freely, holding the handle and saying: "That's me who made you!"

"Hehe, who can tell who!" Qin Lan was obviously not convinced, and provoked Chen Xin: "Would you like to make a bet?"

"Okay, what are you betting on?" Chen Xin was pleased to fight. Although the PS5 was on the market before the disaster, he hasn't tried the latest model yet: "If you lose, you are not allowed to go wrong!"

Qin Lan bit her lip, and after thinking about it, she made up her mind and said, "The one who loses is down at night!"

"Under? You sleep on the lower bunk? What's underneath..." Chen Xin reacted, and the expression on his face suddenly became meaningful: "The bet is so big? Then I'm about to use 12% of my skills. !"

Qin Lan was already embarrassed at this time, but still said very pretentiously: "Humph! I won't lose out anyway, I won't lose, it depends on how you die!"

With that, he cast a provocative look at Chen Xin and immediately started the game.

Chen Xin smiled, and also got serious. It is a matter of man's dignity. You can't lose this kind of thing. Even though losing is actually not a disadvantage for Chen Xin.

——————————————————

The win or loss is aside for the time being. How to decide between the two is not for outsiders. Anyway, when Chen Xin woke up the next morning, Qin Lan was lying in his arms.

Carefully drew out his arm, Chen Xin got up from the bed lightly and put on his clothes. In order to avoid waking Qin Lan, he went to the bathroom of another room to wash, and then he came to the upgraded new kitchen and started to prepare breakfast. .

However, Qin Lan didn't sleep very dead, and the lack of a pillow beside her made her wake up quickly.

Qin Lan, who was only wrapped in a blanket, came to the living room and looked at Chen Xin who was busy in the kitchen. She did not disturb him, but leaned against the kitchen door.

The upgraded heating system provided a warm enough environment for the interior of the refuge. Even if Qin Lan was only wrapped in a blanket, he did not feel cold, but watched Chen Xin busy with interest.

"Get up, why don't you sleep longer?" There were more people at the door of the kitchen, which naturally could not hide from Chen Xin. He raised his head and glanced at Qin Lan, and continued to cut the lettuce that had just been blanched with boiling water.

"You're not here, I can't sleep a bit." Qin Lan looked at Chen Xin, and suddenly said something almost coquettish: "What to eat in the morning?"

"You can't sleep without me?" Chen Xin smiled ~www.ltnovel.com~ after a daring look at her and said: "I made a little lettuce salad and cooked rice porridge, but no salad dressing. I wonder if you are used to eating? Go brush your teeth and you will be able to eat it in a while."

"Lettuce salad? It's good to have fresh vegetables now, how can there be so much fussy." Qin Lan also laughed, wrapped in a blanket and walked to the room: "Then I'm going to brush my teeth."

Qin Lan went to brush his teeth, and the lettuce salad on Chen Xin's side was also cut. Just season it with salt and other seasonings, and you can serve it to the table.

When Qin Lan came out of the bathroom and sat down at the dining table with only a shirt on, the table was already set with dishes and steaming porridge.

"It's better for Axin, you have everything here. Even breakfast is so comfortable!" Qin Lan asked Chen Xin while eating breakfast, "I'm going back to the Municipal Bureau today. How about you Axin? Today? What to do?"

"I plan to make the ground source heat pump required by the municipal government, and I can start early if I finish it early." Chen Xin answered Qin Lan's question, and at the same time asked her, "Shall I take you back?"
