Chen Xin finally persuaded Qin Lan and asked her to agree to stay and take care of his shelter instead of traveling thousands of kilometers with him to go back to his hometown to pick up people.
As for Chen Xin's method of persuading Qin Lan, he naturally let her see the various weapons and equipment he had prepared on the tracked armored RV.
Looking at the radar, drones and heavy machine guns installed by Chen Xin on the car, Qin Lan knew that these things were enough for Chen Xin to protect himself along the way. As long as he was not going to fight against the army or an ordinary robber. , unable to do anything to his armored vehicles.
The only thing that made Qin Lan still worried was that Chen Xin was alone. If something happened on the way, he might not be able to deal with it in time.
However, this was not a problem. Qin Lan did not continue to insist on accompanying Chen Xin on this trip, so after Chen Xin displayed the weapons in the car, Qin Lan did not continue to struggle.
And what Chen Xin said made sense. He might be gone for a month or two, so she had to help Chen Xin take care of his home.
Qin Lan helps with housekeeping, and Mo Qingyan and Mo Qingxin take care of it. Chen Xin has no worries about his home.
Now we just have to wait for the entire shelter to be upgraded and the ground source heat pump required by the city to be manufactured, and then we can set off.
In order to prepare for the upgrade, Chen Xin took a shower at night and went to bed early, in order to put himself in a good state and wait for the overall upgrade of the shelter when he got up early tomorrow morning.
Qin Lan had moved to his room, but neither he nor Qin Lan had any intention of doing some intimate things tonight. Chen Xin climbed into the upper bunk and fell asleep quickly.
Qin Lan was sleeping on the lower bunk, listening to Chen Xin's even breathing after falling asleep on the upper bunk, and fell asleep quickly, but the corners of her mouth were slightly raised, with a satisfied smile on her face.
————————————————————
The next morning, Chen Xin got up very early, even earlier than Qin Lan, who always got up early.
After washing up and making breakfast, Chen Xin called Qin Lan.
Ding Ning had to go back to the city bureau to report the situation yesterday, so he left with Li Tou and the others yesterday. Only Qin Lan stayed with Chen Xin because he was still recovering from his injuries and on vacation.
So this morning's breakfast was just the two of them.
After eating the porridge that Chen Xin specially added with chopped ham, Qin Lan asked Chen Xin: "A Xin, you said you are going to start renovating your home today, so how do you plan to start? Is there anything you want me to help with?"
"Where can I help? I don't have much to help with. I've already completed most of the renovation. The reason why I didn't finish it before was just because I didn't have enough materials." When Chen Xin heard Qin Lan say that he wanted to help, he thought for a moment and declined. Her kindness: "Now that the city government has sent the materials, I can do it alone. Alan, you should have a good rest today."
After saying that, Chen Xin cleared the table and then went to the storage room alone.
When Qin Lan heard Chen Xin say that he didn't need his help, he didn't force it. Instead, he turned on his game console and prepared to take a good rest today as Chen Xin said.
Chen Xin came to the storage room, looked at the materials filled in the storage room, and prepared to start the overall upgrade of the shelter.
Opening the system interface, he controlled his thoughts and focused his attention on the entire shelter. The system interface also displayed options for upgrading the entire shelter.
"Simple Shelter"
"Upgrade plan one: Upgrade the protection level of the shelter, improve the shelter's disaster prevention capabilities, improve survival comfort, the overall technology of the shelter +1, and the required survival points for the upgrade are 12,000."
"Upgrade plan two: expand the living space of the shelter, increase the number of people the shelter can accommodate, and improve the material support capacity of the shelter. The number of people the shelter can accommodate +5, and the survival points required for the upgrade are 15,000."
The upgrade plan was the same as before. Chen Xin did not make adjustments to it, but he had his own detailed ideas for some details of the overall upgrade of the shelter.
Without too much hesitation, he directly put in the various materials in the storage room and chose two options to upgrade at the same time. The survival point consumption reduced to one-tenth still required nearly 3,000 points. This is what Chen has left as a newbie. Two-thirds of the survival points were occupied, and most of the materials stored in the storage room were directly consumed, leaving only a few bits and pieces.
It can be said that Chen Xin's accumulation over the past six months has been consumed in this upgrade.
But as the green light spread to every inch in front of him, Chen Xin closed his eyes with a smile of joy and expectation. He wanted to see a brand new refuge when he opened his eyes.
Counting three two one in his heart, when he opened his eyes again, the green light had dissipated, and the shelter became different.
He was still standing in the storage room, but the storage room had turned into a simple food storage room, with shelves storing various foods in categories.
Chen Xin looked at the food storage room that was as big as the original storage room, and then checked the cold storage that was upgraded with the previous food storage room and refrigerator. Chen Xin nodded with satisfaction and left the storage room.
After walking out of the storage room, what Chen Xin faced should be the original public space, but now it has been upgraded into a hall.
This is one of the changes made after the overall upgrade of the shelter. Chen Xin turned the original shelter into two floors, with the public space serving as a hall connecting the upper and lower floors.
The rooms arranged on the first floor are storage rooms, workshops and medical rooms, as well as a power generation area composed of a ground source heat pump, an algae oxygen generator, and a power distribution room. The passage connecting the planting greenhouse is also arranged on this floor.
The main body of the second floor is a semi-open living room and kitchen. Because the public space runs through the upper and lower floors, one side of the living room happens to be a structure similar to a balcony, which can directly see the first floor.
There are five double rooms scattered around the living room. Each room has its own bathroom and bathing function. However, Chen Xin still built a separate bathroom on the second floor, fulfilling his promise to Qin Lan and creating a hot spring. Bath.
Chen Xin did not go to the second floor, although now he could see Qin Lan sitting in the living room playing games when he looked up, as if she didn't feel anything.
Turn around and go through the passage connecting the planting greenhouse to the planting greenhouse. There have been earth-shaking changes here.
The original square cultivation greenhouse has been transformed into a huge cylindrical structure with a diameter of fifteen meters and a height of twenty meters. And the biggest change is not the space of the cultivation greenhouse, but the cultivation area inside it.
The bottom of the greenhouse has turned into a large one-meter-deep pool, in which several fish are swimming happily. It seems that Chen Xin was too frustrated to raise them in the water tank before, but now he finally has enough space to swim. Moved.
In addition, the original hydroponic planting trays and soil planting areas with only one layer have also been changed into six layers of square hydroponic planting trays with an area of one acre, one layer above the pond, through The circulation system in the greenhouse is used for irrigated cultivation.
The bottom two layers of planting trays are planted with the previous upland rice. It doesn't seem to be much different, but the rhizomes at the bottom are no longer rooted in the soil, but have been replaced by planting trays and nutrient tanks.
On the upper four floors are a quarter layer of carrots, a quarter layer of cabbage, a quarter layer of lettuce, and the remaining quarter layer of strawberries. The other three floors are empty.
These were crops that Chen Xin had planted before. Obviously, the system upgrade only changed the structure of the greenhouse and had no impact on these crops.
The entire planting greenhouse has now entered mechanical automation. Fully automatic planting, maintenance and harvesting are carried out through the operation console at the door. Compared with the previous situation where Chen Xin had to plow the ground and harvest by himself, it is undoubtedly much more advanced.
This is obviously a manifestation of the +1 technology level in the overall upgrade.
After checking the planting greenhouse, Chen Xin came to the power generation area. As the energy supply core of the entire shelter, it can be regarded as the heart area. Especially after the upgrade, Chen Xin connected the ventilation system of the shelter here, and the entire power generation area The area is even more important.
The power generation area is also a large room. On the floor are four ground source heat pumps and matching generators. Against the wall are four huge green glass tanks, which are algae oxygen generators.
However, after they have been upgraded, not only have they become larger in size, but the algae deposits inside can be automatically extracted. Even the algae inside have undergone certain changes and can produce ethanol.
Although the output is not high, it can only provide Chen Xin with one hundred liters of ethanol a month, but this is very good news. At least the shelter has a new product.
The algae oxygen generator is now connected to the ventilation system, and the oxygen it produces is delivered directly to every corner of the shelter through ventilation ducts.
As for the power distribution room, it is still a combination of a power distribution cabinet and a battery, but there are three more battery installation positions next to it, which can be used to install the isotope thermoelectric batteries used by Chen Xin on the armored RV.
Although Chen Xin himself has created an isotope thermoelectric battery, also known as a nuclear battery, he did not directly change the shelter to use a nuclear battery or a nuclear reactor for power supply. He only prepared three isotope thermoelectric batteries in the power distribution room. Batteries serve as backup power.
"It's really good! This way, we don't have to worry about power outages and lack of oxygen." Chen Xin nodded with satisfaction, although the issues of hypoxia and power outages were no longer on his mind.
After checking the power generation area, Chen Xin took another look at the medical room and work area. There were no major changes in the two. The work area only became more advanced with various small lathes and equipment, while the medical room The sterile operating room and a ward are separated, making it look more like a small medical station than just a medical room.
These are the main parts of the shelter after the overall upgrade. However, Chen Xin knows that in addition to these, the entrance area beyond the gate has also undergone earth-shaking changes. At least he has moved the material storage room above and turned it into of the material warehouse.
