Doomsday Bunker Upgrade

If someone can see the upgrade scene of the scientific research base, then in his line of sight, he will see a green beam of light rising from the ground, even going straight to the sky.

The entire scientific research base is now shrouded in green upgrade brilliance. Although there is no major change in appearance, there are many more detailed changes inside.

For example, the most intuitive feeling for Chen Xin is that the room he is in has changed from a square to a fan, and the original bunk bed in the room has become a double bed, which can even be spread out by three people. .

The soft furnishings in the room have also changed, from the more futuristic cold tones to the warm ones that are more like a home, adding a bit of home warmth.

Moreover, the bathroom in the room has changed from only a shower room to a real bathroom and toilet with a series of facilities such as washbasin and bathtub.

These changes all came from the drawings that Chen Xin had designed before. The entire shelter changed from the original two-story square structure to a multi-layer cylindrical structure. The overall building structure was more stable, and the space utilization rate became higher.

Satisfied with the upgraded room, Chen Xin got up from the sofa in the room and walked towards the door.

The smart door sensed Chen Xin's body and opened automatically, revealing a clean, carpeted and brightly lit corridor outside.

These are all brought about by the upgrade, not only the improvement of the technology level, but also the comfort of living in the details.

Stepping on the soft carpet along the corridor to the central elevator, Chen Xin pressed the button, and the elevator soon went up.

Move the elevator from the corner of the original shelter to the center of the original column, which can save space, and at the same time, other equipment that needs to run through the entire shelter can also be placed in the center. Occupied space, so as to enhance the spaciousness of each floor in use, so as not to feel that you are underground and the space is narrow.

The elevator door opened, and Chen Xin walked into the elevator, surrounded by dynamic landscape paintings.

This is also one of the changes added by this upgrade, from Mo Qingxin's proposal.

She felt that everyone lived underground for a long time, and it was dark outside, and people would be depressed after a long time, so when Chen Xin asked her what to add to the shelter renovation, she expressed that she hoped to be able to see the scenery before the disaster.

So Chen Xin added an electronic window to each room of the shelter after the upgrade, which can play the scenery before the disaster or the picture of a certain city 24 hours a day, and the elevator did the same. The only difference is that the four walls in the elevator are all electronic display screens, and you can enjoy the scenery 360° without dead ends.

It has to be said that the once beautiful scenery can indeed bring physical and mental pleasure. If it is someone who has been depressed for too long in the current disaster environment, they may even be addicted to it.

Of course, this has no effect on Chen Xin. It's not that his resistance is high enough, or his heart has no turbulence, but Chen Xin has prepared a room for himself with holographic image projection, sound, smell simulation, and even air flow, Changes in light, temperature, etc. can be completely simulated holographic image room.

There, you can not only enjoy the scenery of the past, but even make people truly immersive, as if returning to the past.

So just a few dynamic landscape paintings in the elevator are indeed not very attractive to Chen Xin.

Taking the elevator to the top floor of the shelter, Chen Xin stepped out of the elevator, walked through the corridor to the gate, paused for a while, and then opened the heavy gate.

The gate is still the same as before, and Chen Xin has not made any structural changes to it, but the internal material and protection performance have been improved a lot in the upgrade, at least now even missiles are difficult to break through, especially Chen Xin has installed an energy shield on the gate.

As for the original machine gun defense still retained, Chen Xin did not make any further upgrades to the 12.7mm rotary machine gun, after all, this thing is enough as a defensive weapon.

After all, if someone can penetrate the heavily guarded scientific research base in front and kill him all the way to his shelter, even if he upgrades the machine gun at the door to a howitzer, it won't work much, unless two Warhammer 40K worlds are placed at the door. Knight Titan, otherwise the enemy of this series can't be stopped by automatic defense weapons alone.

Walking out of the gate, Chen Xin did not close the gate behind him, because now there is actually a closed corridor connected to the ecological dome at the gate of his shelter.

So even if Chen Xin didn't close the door, it wouldn't have any effect on the shelter, and if someone came to him later, it would be troublesome to wait for the door to open every time.

Walking along the road in the dome, the temperature in the entire ecological dome is maintained at about 20°C, and the main source of heat supply is the heating hub standing in the center of the dome.

This heating hub is connected to the energy tower of the geothermal power plant through pipes. After the first use of the geothermal power plant, the hot water will be piped here for the second round of heat dissipation, thereby providing heat for the entire ecological dome.

Because there are no plants planted in the ecological dome, it looks relatively empty, but the water circulation system is still working well.

There are several recovery water tanks around the heating hub, which are connected to the surrounding support columns and the top metal support structure of the dome. The dome that has been modified during the upgrade process can effectively recover the water vapor in the air, and then support it through the top metal support. The hollow pipe in the middle collects the water drop by drop.

These collected water droplets will eventually flow along the water tank to the annular reservoir below the heating hub. The reservoir and the heating hub are together made into a park pool, but in fact its main function is to Provides evaporation of water vapour to avoid over-drying of the air because the heating hub has been supplying heat.

Around the heating hub is a reserved ecological area, and several annular planting troughs are already in place, just waiting for plants to be planted in them.

As for the seeds of plants, Chen Xin doesn't need to worry about this. The relevant seeds have been mobilized and will be delivered soon.

Except for the central ecological area, the surrounding area is the office area and the experimental area. Everything is divided according to the previous plan. The upgrade of the ecological dome mainly focuses on improving the ecological circulation capacity of the dome itself, as well as the scientific and technological level of the laboratory. What changes have been made.

Looking at all this with satisfaction, Chen Xin came to the underground ordnance equipment test area through the elevator, intending to see the situation of Xiaofeng.
