Doomsday Bunker Upgrade Chapter 440: New 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, and 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, and even three people can lie on it. Spread out.

The soft furnishings in the room have also changed, from the more recent and futuristic cool colors to the warm colors that are more like a home, adding a bit of home warmth.

And 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 come from the blueprints that Chen Xin has designed before. The entire shelter has changed from the original two-story square structure to a multi-layered cylindrical structure. While the overall building structure is more stable, the space utilization rate has also become more efficient. high.

Chen Xin, satisfied with the upgraded room, stood 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 and walking 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. It will not be occupied by space, thus enhancing the spaciousness of each floor in use, and will not 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, as suggested by Mo Qingxin.

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

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

It has to be said that the once beautiful scenery can indeed bring physical and mental pleasure, and people who have been depressed for too long in the current disaster environment 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. It's that Chen Xin has prepared a room for himself with holographic image projection, sound, smell simulation, and even Changes in air flow, 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 really not very attractive to Chen Xin.

Taking the elevator to the top floor of the shelter, Chen Xin stepped out of the elevator and walked through the corridor to the gate. After a short pause, he opened the heavy gate.

The gate is still the same as before. Chen Xin has not made any structural changes to it. However, 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, Chen Xin did not upgrade the 12.7mm revolving 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 of him and get all the way to his shelter, even if he upgrades the machine gun at the door to a howitzer, it won't help much unless he puts two warhammers at the door. The Knight Titan in the 40K world, otherwise the enemy of this series cannot be stopped by automatic defense weapons alone.

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 forward along the road in the dome, the temperature in the entire ecological dome is maintained at about 20℃, 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 pipelines~IndoMTL.com~ After the first utilization of the geothermal power plant, the hot water will be piped here for the second round of heat dissipation, so as to provide The entire eco-dome provides heat.

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 pass it through A hollow tube in the top metal support collects the water drop by drop.

These collected water droplets will eventually flow down the water tank to the annular reservoir below the heating hub. The main function is to provide evaporation of water vapor to prevent the air from becoming too dry because the heating hub has been supplying heat.

Around the heating hub is a reserved ecological zone. Several annular planting troughs are already in place, just waiting 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. No structural changes have been made.

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