Doomsday Bunker Upgrade Chapter 85: Upgrade the gate
"Ordinary refuge entrance"
"Upgrade plan 1: Increase the thickness of the protective door, enhance the defense of the refuge entrance, add a biochemical radiation decontamination room, and upgrade the required survival point of 1500"
"Upgrade plan 2: add screen doors, add partition doors, add new equipment rooms, upgrade the air intakes of the shelter ventilation system, and upgrade the required survival points 1350"
Looking at these two upgrade plans, Chen Xin, who had already obtained enough supplies from the SWAT team, did not consider which plan was more suitable, so he chose to upgrade all of them.
For Chen Xin, who can now get 15 survival points per day, when he has sufficient materials to reduce the consumption of survival points to 10%, the consumption of the upgrade method of choosing all of the two plans is already in his hands. within the acceptable range.
It's just that Chen Xin himself didn't expect that an oxygen generator box made with only a few Survival Points could provide him with two Survival Points every day, which was beyond Chen Xin's expectations.
However, this is not difficult to understand. After all, his upgraded algae oxygen generator not only produces oxygen, but also uses the generated biomass to ferment to produce biogas, which is used for fuel cell power generation.
It means that this device is equivalent to the functions of the oxygen generator, biomass incubator and fuel cell. It has greatly improved Chen Xin's current living conditions, so he can obtain more The survival point is also understandable.
After choosing all upgrades, the door of the refuge was upgraded to what he drew on the design drawing according to Chen Xin's ideas under the power of the system.
A sturdy and heavy protective door, a decontamination room that can be used for radiation and biochemical cleaning, a maintenance room that can park cars and organize equipment, and a defense corridor with heavy crossbows...
Today's refuge has what a real doomsday refuge should look like, with a solid and reliable defense.
drove up the car that had been parked below and parked it in the maintenance room. Chen Xin also brought up the equipment he might use when going out.
Hanging the heavy protective clothing in the closet of the preparation room, all the equipment and the materials needed to go out are also neatly stacked. Chen Xin looked at the neat and tidy everything in front of him, and felt a sense of satisfaction and pride in his heart. Feel.
It’s like the sense of accomplishment that you get when you play Minecraft and finally build a hut that makes you feel safe and secure.
And different from the game, this is the real world, this is the real refuge, this is the real refuge that can protect Chen Xin's safety.
Through the renovation and upgrade of the entrance to the shelter, Chen Xin also moved the air vent and short-wave antenna that originally led to the mountainside to the top of the entrance and placed it in a small bunker made of thick reinforced concrete.
This bunker is not big, it's just a small space, located above the sanitation room at the entrance of the refuge, somewhat similar to a machine gun bunker in a war game.
This is not a machine gun bunker, although in a sense, as long as Chen Xin mounts a machine gun here, it can indeed be used as a machine gun bunker.
But the actual function of this small bunker is to protect the shortwave antenna and vents that have been moved here. It is not true that Chen Xin wants to build a machine gun bunker here.
Although it is likely to become a defensive facility in future upgrades, it is now only a shelter for shortwave antennas, and at most it serves as a ventilation function.
The outside of the bunker is covered by the dirt of the mountain itself, leaving only a gap about the width of a palm. It is impossible to enter the bunker from the outside. It can only be entered through the passage reserved inside the shelter.
Compared with the short-wave antenna that was only covered by a camouflage cloth and placed directly in the open air, the short-wave antenna under the protection of such a small bunker is undoubtedly much safer. Even if it is discovered, it is difficult to destroy this kind of An antenna placed in a solid cover.
As for the impact of the cover on the antenna signal, it is not without it, but it is not serious. At least Chen Xin tried it. He can still receive external signals smoothly and communicate with others.
The original vent has also been changed after being transferred to the inside of the bunker. Not only are the protective covers and grille filters added, but the vent pipe also has an overpressure automatic exhaust after entering the interior of the shelter. valve.
This is a ventilation device that will be used in civil air defense projects. The principle is to use the air pressure difference between the inside and outside of the shelter to form a seal, block the intrusion of toxic and harmful air from the outside, and discharge the air inside the shelter. Ensure ventilation circulation.
Although it sounds a bit complicated, the structure of this thing is very simple. With it, there is no need to worry about external toxic and harmful substances entering the shelter through the ventilation pipe.

At the entrance of an original shopping mall in the urban area, Qin Lan and a few special policemen are guarding here with guns in hand.
This is the original large shopping mall in the city, with an underground supermarket and parking lot. Before the disaster, it was planned as a small shelter, which houses about 5,000 people from the surrounding communities~IndoMTL.com ~ The plan for this kind of small refuge was originally intended to allow some people to escape the doomsday disaster, and to connect to other refuges by passages after the disaster and use it as an underground residential area.
However, due to the deterioration of the environment and the temporary inability to supply oxygen production equipment to small shelters, the city government can only transfer people to other medium-sized shelters and temporarily seal this small shelter.
intends to wait until the passage connecting the medium-sized refuge here is opened up, and the oxygen generation equipment has surplus, before reopening.
Qin Lan and the others are here to help these people with the transfer. In addition to them, there are also city staff who are in charge of the transfer.
The second batch of oxygen generators was shipped in not long ago, but this batch is much smaller than the previous batch, with only four small biological oxygen generators.
Two of them were naturally transported to Binhu Community and Polytechnic Institute, two medium-sized refuges that were not allocated oxygen production equipment before, while the remaining two were given to the refuge where the armed police force was located. , And the other one was distributed to the factory.
It is precisely because of insufficient oxygen production equipment that the city government decided to temporarily abandon all small refuges, and all population diversion channels for medium-sized refuges.
Although the population in the small shelters is small, there are only a few thousand people, but the transfer of thousands of people is not an easy task. The staff sent by the city government are already a little overwhelmed, and all kinds of problems are need them to deal with it.
Qin Lan was standing on the firing position of the armored car with her sniper rifle, constantly patrolling the crowd, searching for possible dangers.
Under these circumstances, everything can happen. Qin Lan and the others must put an end to any possible criminal behavior and avoid evolving into mass incidents.
