Chapter 441

If someone can see the upgrading scene of the scientific research base, then in his line of sight, he will see a green light column rising up, even soaring into the sky.

At this time, the whole scientific research base is enveloped in the glory of green upgrading. Although there is no big change in appearance, there are many changes in details inside.

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

The soft clothes in the room have also changed, from the cold color of more recent future feeling to the warm color of more like a home, adding the warmth of several families.

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

These changes come from the drawings that Chen Xin had designed before. The whole refuge has changed from the original two-story square structure into a multi-storey cylindrical structure. The overall structure is more stable and the space utilization rate is also higher.

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

The intelligent door senses Chen Xin's body and opens automatically, revealing the clean, carpeted and brightly lit corridor outside.

These are brought about by the upgrading, not only the upgrading of the level of science and technology, but also the comfort of living from the details.

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

Move the elevator from the corner of the original shelter to the center of the original column, which can save space. At the same time, other equipment that needs to run through the whole shelter can also be placed in the center, so that each floor of the shelter will not be occupied by space, so as to enhance the spacious feeling of each floor in use, and not feel that the space is narrow and underground.

The elevator door opens and Chen Xin walks into the elevator, surrounded by dynamic landscape paintings.

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

She felt that people lived underground for a long time, and it was dark outside. After a long time, people would be depressed. So when Chen Xin asked her what to add to the reconstruction of the refuge, she said that she hoped to see the scenery before the disaster.

So after the upgrade, Chen Xin added an electronic window in each room of the shelter, which can play the scenery before the disaster or the picture of a city 24 hours a day. The same change has been made in the elevator, except that the four walls in the elevator are all electronic displays, which can enjoy the scenery 360 ° without dead angle.

It has to be said that once beautiful scenery can really bring physical and mental pleasure. If people have been depressed for too long in this disaster environment, they may even indulge in it.

Of course, this has no effect on Chen Xin. It's not that he is resistant enough or that he doesn't have any trouble with it in his heart. It's that Chen Xin has prepared for himself a holographic image room with holographic image projection, sound and smell simulation, and even air flow, light, temperature and other changes that can be fully simulated.

There you can not only enjoy the scenery of the past, but also make people really immerse themselves, as if back to the past.

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

Taking the elevator to the top floor of the shelter, Chen Xin stepped out of the elevator, crossed the corridor and came to the gate. After a slight pause, he opened the heavy door.

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 greatly improved in the upgrade. At least now, even the missile is hard to burst, especially Chen Xin has installed the energy shield on the gate.

As for the original machine gun defense, Chen Xin did not upgrade the 12.7mm Gatling machine gun. After all, it is enough to be used as a defensive weapon.

After all, if someone can break through the front heavily guarded scientific research base and kill all the way to his refuge, even if he upgrades the machine gun at the door to a howitzer, it won't be very effective. Unless two 40K world knight titans are placed at the door, this kind of enemy can't be stopped by automatic defense weapons alone.

After going out of the gate, Chen Xin did not close the gate behind him, because there is a closed corridor connecting the ecological dome at the gate of his refuge.

So even if Chen Xin doesn't close the gate, it won't have any impact on the shelter. Moreover, if someone comes to him later, it's very troublesome to wait for the gate to open every time.

Walking along the road in the dome, the temperature of the whole 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.

The heat supply hub is connected with the energy tower of the geothermal power plant through pipes. After the first utilization of the geothermal power plant, the hot water will be transported here by pipes for the second round of heat dissipation, so as to provide heat for the whole ecological dome.Because there are no plants planted in the ecological dome, it is relatively open, but the water circulation system is still working well.

There are several recycling water tanks around the heating hub, which are connected with the surrounding supporting columns and the top metal supporting structure of the dome. The dome that has been modified in the upgrading process can effectively recover the water vapor in the air, and then collect the water droplets bit by bit through the hollow pipes in the top metal supporting.

These collected water droplets will eventually flow along the sink to the circular reservoir under the heating hub. The reservoir and the heating hub are made into a park like pool, but in fact its main function is to provide water vapor evaporation, so as to avoid the air becoming too dry because the heating hub is heating all the time.

Around the heating hub is the reserved ecological area, and several annular planting slots have been put in place, just waiting for plants to be planted.

As for the seeds of plants, there is no need for Chen Xin to worry about this. The relevant seeds have been mobilized and will be sent soon.

Apart from the central ecological area, there are office areas and experimental areas around. Everything is divided according to the previous planning. The upgrading of the ecological dome mainly focuses on improving the ecological circulation capacity of the dome itself and the scientific and technological level of the laboratory, and there is no structural change.

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 mocking wind.
