    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 facilitate the entry and exit of cars parked inside the shelter, but 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 large, which makes it inconvenient to use, but it¡¯s not that it can¡¯t be used at all.

    But now that the system can be used to upgrade, 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.

    Taking 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 that Chen Xin made due to the inconvenience of material transportation before. The material warehouse was placed on the upper floor where the entrance is, and only the food storage room was kept inside the shelter.

    In this way, materials can be transported in from the door and stored directly, 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 take them personally.

    Passing through the maintenance room, there is still the passage where the heavy crossbow is placed.

    Chen Xin has not made any major changes here. After all, it is just a passage, and the attack capability 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 induction 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. The power 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 up from the inside and triggered 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 facial recognition, the heavy crossbow on the ceiling will be activated, allowing you to enjoy a 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 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 been replaced with 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 3600 revolutions of one breath and the great compassion to save the world.

    After inspecting the entire shelter, Chen Xin wondered about the effects of the overall upgrade  "

    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.

    By the time 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 required by the city. 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?" (Recorder  Please visit our website: www.hlnovel.com
