Chapter 209

Originally, Chen Xin's connecting passage between the main part of the shelter and the entrance part was a 50 meter long ramp. At that time, it was built to facilitate the cars parked inside the shelter to get in and out of the shelter, but in fact, the use of this corridor was not as convenient as originally expected.

Because the length is only 50 meters, but the height difference from the entrance to the shelter is nearly 20 meters, which makes the slope very steep. It's not very convenient to drive in and out, or even to drag materials with a cart.

But at that time, when building the shelter, Chen Xin only thought about building the shelter a little deeper to avoid possible meteorite impact on the shelter. He wanted to use the soil layer more than 200 meters above the shelter as protection, so he didn't have to worry about too many details.

After all, it's just that the slope is relatively large, so it's not very convenient to use. It's not totally unusable.

However, now that the system can be upgraded, Chen Xin has also adjusted the corridor. The original inclined connection corridor has been changed into two horizontal passages, and the elevator is used in the middle to go up and down.

This is one of the reasons why Chen Xin had to wait until the materials from the municipal government were delivered before upgrading the whole refuge. The materials for the elevator were collected by the help of the municipal government. Originally, Chen Xin planned to process them by himself.

After upgrading, the elevator area can stop an ordinary family car. The whole car is a tubular car with a diameter of 7 meters and a height of 3.5 meters. The bottom of the car can rotate. This solves the problem that the car can't turn around because of the narrow access.

Take the elevator to the upper floor. After passing through the passage, it is still the original servicing room, but on the other side of the servicing room, there is an additional material storage warehouse.

This is an adjustment made by Chen Xin due to the inconvenient transportation of materials before. He put the material warehouse on the upper floor where the entrance is, and only the food storage room is kept inside the shelter.

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

Anyway, for Chen Xin, where the materials are put is almost the same. He only needs to open the system interface to use the materials, and does not need to pick them up in person.

Through the preparation room, it is still the channel where the crossbow is placed.

Chen Xin didn't make any big changes here. After all, it's just a channel. The attack ability of Heavy Crossbow is enough.

His only adjustment is the trigger mode 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 whole Heavy Crossbow in the ceiling.

Anyone who crosses the corridor when the alarm is on will be directly hit by a heavy crossbow with 90 rounds per minute, which is no less powerful than Chen Xin's heavy machine gun at the gate.

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

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

However, if a stranger enters but fails to pass face recognition, the Heavy Crossbow on the ceiling will be activated to enjoy the experience of dodging the heavy crossbow.

As for going out through the safety channel, Chen Xin didn't make any changes in the decontamination room, just upgraded the decontamination equipment inside.

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

This is an L-shaped space. The short side is connected with the gate and the decontamination room, while the long side is used to park the armored RV after Chen Xin's magic transformation for an extended garage.

There's nothing to say about the garage and the porch. The garage only adds the function of vehicle maintenance and some repair tools, and the porch is just an open space.

What's really remarkable is the gate of the sanctuary.

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

The original double mounted Markham at the door has also been replaced by a double mounted 12.7mm three barrel Gatling machine gun, which is the same type as Chen Xin's armored RV. It can still be controlled by computer and aimed by automatic lock.

Of course, you can still exercise like Chen Xin did yesterday, and experience 3600 turns at a breath, showing great compassion to the world.

After reviewing the whole shelter, Chen Xin was very satisfied with the overall upgrading effect. In addition to the improvement of the overall pattern and the level of science and technology, even the original gray concrete wall of the shelter was covered with paint, and the metal support frame was added, which made it look clean, tidy, spacious and bright.

Even the lighting facilities that used to be just light bulbs have been replaced with LED tubes, which softens the light inside the shelter. What's more, it adds the light control that Chen Xin has always cherished. The lighting can be adjusted with the change of time, so that people inside the shelter can feel the passage of time.As for Chen Xin's observation room, which was originally set above the gate, has also been adjusted and upgraded this time. It has evolved from a simple tree antenna room to a formal blockhouse. Not only some living facilities have been added inside, but also a double-layer vacuum glass has been added to the observation port to block the entrance 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 make it return to the shooting hole.

As for the vent connected to the external wall, Chen Xin did not make any major changes, but added a ventilator and air filter inside the ventilation duct to improve the ventilation efficiency.

Back inside the shelter, Qin LAN is still sitting on the sofa playing games. Chen Xin's previous experience seems to have no effect on her. Although her living room has completely changed, the game console has been upgraded from PS4 to ps5, and even the size of the TV has been enlarged a lot.

"The work is done?" Qin LAN watched Chen Xin pick up another handle on the side to access the game, and also pressed the pause to switch the game out to double mode.

Chen Xin sat down, nodded and said, "I don't have much work left. As long as the materials are in place, it can be done quickly. Now it's all finished."

"If you're done, come and play with me. Last time you lost to me, now you have a chance to win me!" Qin LAN looks at Chen Xin and deliberately uses a method to motivate him.

Chen Xin also a free and easy smile, holding the handle said: "that is I let you!"

"Ha ha, who let who also perhaps!" Qin LAN is obviously unconvinced and challenges Chen Xin: "how about a bet?"

"All right, what's the bet?" Chen Xin gladly responded. Although the ps5 was launched before the disaster, he hasn't tried the latest model yet: "you can't default if you lose!"

Qin LAN bit his lip, thought about it and then made up his mind to say: "the loser is below at night!"

"Down there? Don't you sleep in the lower berth? What's next... " Chen Xin responded, and the expression on his face suddenly became meaningful: "bet so much? Then I'm going to use 12% of my skill! "

Qin LAN now is full of shame, but still very brave said: "hum! Anyway, I won't lose. I'll see how you die! "

With that, he threw a provocative look at Chen Xin and started the game directly.

Chen Xin smiles, and is also serious. It's a matter of man's dignity. This kind of thing can't be lost. Even if it's lost, it's nothing for Chen Xin to lose.

It's not enough to know how to decide between them. Anyway, when Chen Xin woke up the next morning, Qin Lan was lying in his arms.

After carefully pulling out his arm, Chen Xin gets up from the bed and puts on his clothes. In order to avoid waking Qin LAN, he goes to the bathroom of another room to wash, and then comes to the upgraded new kitchen to prepare breakfast.

However, Qin LAN didn't sleep very much. The lack of pillow people around her made her wake up quickly.

Qin LAN, wrapped in a blanket, comes to the living room and looks at Chen Xin, who is busy in the kitchen. Instead of disturbing him, she leans against the kitchen door.

The upgraded heating system provides a warm enough environment for the shelter. Even if Qin LAN is wrapped in a blanket, she doesn't feel cold. Instead, she watches Chen Xin busy with great interest.

"Get up, why don't you sleep a little longer?" There are many people at the kitchen door, which naturally can't hide from Chen Xin. He looks up at Qin LAN and continues to cut the lettuce that has just been scalded with boiling water.

"I can't sleep without you." Qin LAN looked at Chen Xin and suddenly said something almost coquettish: "what do you eat in the morning?"

"You can't sleep without me?" Chen Xin gave her a smile and looked at her fondly, then said, "I made some lettuce salad and cooked porridge, but I don't know if you are used to it without salad dressing? Go brush your teeth and you'll be able to eat in a moment. "

"Lettuce salad? It's good to have fresh vegetables now. There's not so much fussiness. " Qin Lan also laughed, wrapped in a blanket and went to the room: "then I'll brush my teeth."

Qin LAN goes to brush her teeth, and Chen Xin's lettuce salad is also cut. Just use salt and other seasonings to flavor it, and you can serve it on the table.

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

"Ah Xin, it's better for you to have everything here, even breakfast is so comfortable!" While eating breakfast, Qin LAN asked Chen Xin, "I'm going back to the Municipal Bureau today. How about you, ah Xin? What are you going to do today? "

"I plan to make the ground source heat pump that the municipal government wants. If I finish it early, I can start early." Chen Xin answers Qin Lan's question and asks her, "do you want me to take you back?"
