Originally, the connecting passage between the main part of the new shelter and the entrance was a 50-meter-long corridor diagonally upwards. It was built to make it easier for cars parked inside the shelter to enter and exit the shelter. However, in fact, this The corridor is not as convenient to use as originally expected.
Because the length is only fifty meters, but the height difference from the entrance to the interior of the shelter is nearly twenty meters, the slope is actually very steep, making it difficult to drive in and out or even use a trolley to haul supplies. very convenient.
But when building the shelter at that time, all Chen Xin considered was to build the shelter deeper to prevent possible meteorite impacts from affecting the shelter. He wanted to use the more than 200 meters of soil above the shelter as protection, so he also There is no need to worry too much about the details.
After all, it's just that the slope is relatively steep, making it inconvenient to use, but it's not that it's completely unusable.
But now that the system can be used for upgrades, Chen Xin naturally made adjustments here, changing the originally diagonally connected corridor into two horizontal passages, with an elevator in the middle for going up and down.
This is one of the reasons why Chen Xin had to wait until supplies from the city government were delivered before starting the overall upgrade of the shelter. The materials for the elevator were collected with help from the city government. Originally, Chen Xin planned to process them himself. .
The elevator that appears after the upgrade has an area that can roughly park an ordinary family car. The whole is a cylindrical car with a diameter of seven meters and a height of 3.5 meters. The bottom of the car can rotate, which solves the problem of vehicles entering and exiting the passage. The problem of being too narrow to turn around.
Take the elevator to the upper floor. After passing through the passage, there is still the original maintenance room, but there is an additional material storage warehouse on the other side of the maintenance room.
This is an adjustment made by Chen Xin due to the inconvenience of material transportation before. The material warehouse is placed on the upper floor where the entrance is, and only the food storage room is kept inside the shelter.
In this way, materials can be stored directly after being transported in from the door, without the need to transport them further.
Anyway, for Chen Xin, the materials are pretty much the same wherever they are placed. He only needs to open the system interface to use the materials, and does not need to pick them up personally.
Passing through the maintenance room, there is still the passage where the heavy crossbow is placed.
Chen Xin did not make any major changes here. After all, it is just a passage, and the attack power of the heavy crossbow is sufficient.
The only thing he adjusted was the triggering method of the heavy crossbow, changing it from the original flip mechanism to an infrared sensor automatic shooting, and also set up a hidden mechanism to hide the entire heavy crossbow in the ceiling.
Anyone who walks through the corridor with the alarm on will be directly shot in the face by a heavy crossbow with ninety rounds per minute, which is no worse than the heavy machine gun installed by Chen Xin at the gate.
As for how 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, every time you come out from the inside, you can turn on the alarm switch and turn on face recognition. In this case, after passing the face recognition, you can naturally enter the shelter.
But if a stranger enters and fails to pass the face recognition, the heavy crossbow on the ceiling will be activated, allowing you to enjoy the thrilling experience of dodging the heavy crossbow's continuous fire.
As for coming out through the safety passage, Chen Xin did not make any changes in the decontamination room, but only upgraded the decontamination equipment inside.
Outside the decontamination room is still the garage and a space that can be called the foyer or entrance.
This is an L-shaped space, with the short side connecting the door and the decontamination room, and the long side being the extended garage to accommodate Chen Xin's modified armored RV.
There is nothing much to say about the garage and the entrance. The garage only adds vehicle maintenance functions and some repair tools, while the entrance is just an open space.
What really deserves attention is the door of the shelter.
It is still the previous lift-type metal armor door, but this time Chen Xin changed it from homogeneous armor to multi-layer composite armor, and the thickness increased from 30cm to 35cm. Although the thickness only increased by 5cm, the defensive performance is equivalent to 120cm thick homogeneous metal armor.
The original twin-mounted Maxim at the door has also been replaced by a twin-mounted 12.7mm three-barreled rotary machine gun. It is the same type as the one installed by Chen Xin on the armored RV. It can still be controlled by a computer and automatically lock the head for aiming.
Of course, you can still perform manual exercises like Chen Xin did yesterday and experience the 3,600 revolutions of one breath and the great mercy that saves the world.
After inspecting the entire shelter, Chen Xin was very satisfied with the effect of the overall upgrade. In addition to the improvement in the overall layout and technology level, even the original gray cement walls of the shelter were covered with paint, and metal was added. The supporting frame looks much cleaner, more spacious and brighter.
Even the lighting facilities that were originally just light bulbs have been replaced with LED tubes, which makes the lighting inside the shelter much softer. It also adds the lighting control that Chen Xin has always been thinking about, which can adjust the lighting as time changes. , so that people inside the shelter can also feel the passage of time.
As for Chen Xin’s original observation room above the gate, it has also been adjusted and upgraded this time, allowing it to evolve from a simple room with tree antennas to a formal bunker. Not only are some living facilities added inside, but also the observation room above A double-layer vacuum glass was also added to block the entry of cold air.
Of course, in order to retain the defensive function of the observation room, the glass of the observation port can be opened to turn it back into a shooting hole.
As for the vents connected to the exterior wall, Chen Xin did not make major changes. He only added ventilation fans and air filters inside the ventilation ducts to improve ventilation efficiency.
Back inside the shelter, Qin Lan was still sitting on the sofa playing games. Chen Xin's previous experience seemed to have no effect on her, even though the living room she was in had completely changed and the game console had been upgraded from PS4 to PS5. , even the size of the TV has been enlarged a lot.
"Are you done?" Qin Lan watched as Chen Xin picked up the other controller and connected it to the game. He also pressed pause and switched the game to two-player mode.
Chen Xin sat down, nodded and said, "There isn't much work left. As long as the materials are in place, it can be done quickly. It's all done now."
"That's it. Come and play a round with me. 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 provocation against him.
Chen Xin also smiled freely, held the handle and said, "That's what I asked you to do!"
"Haha, it's still unclear who will let whom!" Qin Lan was obviously not convinced and challenged Chen Xin: "How about a bet?"
"Okay, what are you betting on?" Chen Xin readily accepted the challenge. Although the PS5 was launched before the disaster, he had not tried the latest model yet: "Don't default on your money if you lose!"
Qin Lan bit her lip, thought for a while and then made up her mind and said, "The loser will stay down there tonight!"
"Down below? Aren't you sleeping on the lower bunk? What's down there..." Chen Xin reacted, and the expression on his face suddenly became meaningful: "Such a big bet? Then I have to use 120% of my strength. !”
Qin Lan was already ashamed at this time, but she still said very bravely: "Humph! Anyway, I won't suffer any loss whether I win or lose. Let's see how you die!"
With that said, he gave Chen Xin a provocative look and started the game directly.
Chen Xin smiled and became equally serious. It was about a man's dignity, and he couldn't lose in this kind of thing. Even if he lost, Chen Xin would actually suffer nothing.
————————————————————
Winning or losing aside, how to decide between the two is not open to outsiders. Anyway, when Chen Xin woke up the next morning, Qin Lan was lying in his arms.
Carefully pulling out his arm, Chen Xin got up from the bed and put on his clothes. In order to avoid waking Qin Lan, he went to the bathroom in another room to wash up, and then went to the upgraded new kitchen to start preparing breakfast. .
However, Qin Lan did not sleep deeply. The lack of someone beside her made her wake up quickly.
Qin Lan, wrapped only 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 inside the shelter. Even though Qin Lan was only wrapped in a blanket, she did not feel cold. Instead, she watched Chen Xin busy with interest.
"You're up, why don't you sleep a little longer?" There was an extra person at the door of the kitchen, which naturally couldn't be hidden from Chen Xin. He raised his head and glanced at Qin Lan, still continuing to cut the lettuce that had just been blanched with boiling water.
"I can't sleep since you're not here." Qin Lan looked at Chen Xin and suddenly said something almost coquettish: "What do you want to eat in the morning?"
"You can't sleep without me?" Chen Xin smiled, looked at her fondly and said, "I made some lettuce salad and cooked porridge, but there is no salad dressing. I don't know if you can eat it." Are you used to it? Go brush your teeth and you’ll be able to eat it in a while.”
"Lettuce salad? It's great to be able to eat fresh vegetables now. Why are there so many picky things?" Qin Lan also laughed and walked to the room wrapped in a blanket: "Then I'm going to brush my teeth."
Qin Lan went to brush her teeth. Chen Xin's lettuce salad was also cut. It only needed to be seasoned with salt and other seasonings before it was served to the table.
When Qin Lan came out of the bathroom and sat down at the dining table wearing only a shirt, the table was already covered with bowls, chopsticks and steaming porridge.
"It's better here, A Xin, you have everything, even breakfast is so comfortable!" Qin Lan asked Chen Xin while eating breakfast: "I have to go back to the city bureau today, what about you, A Xin? Today What to do?”
"I plan to build the ground source heat pump that the city government wants. If I finish it early, I can start early." Chen Xin answered Qin Lan's question and asked her at the same time: "Do you want me to take you back?"
