Doomsday Bunker Upgrade

Whether Li Wensheng switched to diesel Chen Xin is unknown, but after he made another oxygen generator, the materials on hand were also exhausted. The remaining six group friends who needed an oxygen generator could only wait for him to get from Qin Lan. After getting new supplies there, you can get the goods.

The other six group friends who knew this naturally couldn't hold back. In this case, waiting for one more day would increase their chances of encountering danger by one point.

But scouring the material is not an easy task.

Among the materials that Chen Xin needed to make the oxygen generator, glass was the easiest to obtain. After all, if you don't mind broken glass, this thing is really everywhere now.

As for the pipeline, it's easy to say that if you go to the community where no one lives, you can still get it together.

It's just the vacuum pump and the fill light. These two are not easy to collect. There are two group friends who have spare parts for the fill light, but no one really has any spare parts for the vacuum pump.

So despite the urgency, except for the "doctor" who got the oxygen generator, Li Wensheng and two other group friends, the other six group friends still have to wait until next month.

After sending out four oxygen generators, plus Mo Qingyan's harvest, Chen Xin received a total of 600 survival points, and an additional 16 daily survival points per day.

Now Chen Xin has been able to gain 18+16 points of survival every day, and the monthly credit has exceeded 1,000 points.

Compared to when Chen Xin first obtained the system, his monthly income was only over 300 points, which was a rapid increase.

This also made Chen Xin understand how the system obtained daily survival points.

One is naturally the method he is using now, to improve the living conditions of his sanctuary.

One is to help others, so that more people can improve their living conditions.

The two have their own advantages and disadvantages, and it does not mean that the latter is necessarily better than the former, but one may be slower to survive, and the other is faster but has certain dangers.

After all, under the disaster of the last days, the darkness of people's hearts breeds. Whether helping others is helping others or harming oneself needs to be well controlled.

Therefore, helping others appropriately, allowing oneself to gain more survival points, and at the same time creating a safer and more comfortable shelter for oneself is a more appropriate approach under the premise of ensuring one's own safety.

And Chen Xin, who finally got rich, still did not hold back his desire to upgrade and upgraded the kitchen.

The kitchen is the place that Chen Xin considered upgrading when he got the system. Originally, it was only the place where the induction cooker and kitchen utensils were placed. After Chen Xin's upgrade, it was transformed into a formal stove, and there was an extra row of cabinets on the wall. , it looked like it was finally happening.

However, the upgrade of the kitchen did not bring new daily survival points for Chen Xin.

This is not too difficult to understand, after all, even if the kitchen is upgraded, Chen Xin still eats those things every day.

Unless it means that he can get more ingredients and can cook exquisite and delicious dishes in the kitchen, this can be regarded as improving the living conditions.

As for the medical room, because there are still some materials lacking, Chen Xin can only wait for Qin Lan to send the supplies and materials he wants this month before he can upgrade.

Otherwise, he will only spend 10 times the survival points to upgrade.

Although this is not impossible, Chen Xin still insists on saving if he can.

And in addition to upgrading the medical room, he also has to upgrade the power system, which is a big deal.

After all, the power system in Chen Xin's plan also needs to be connected to biogas fuel cells, and if you want to have biogas, you must first get a biogas digester.

The biogas digester must not be dug immediately, it can only be obtained by upgrading the algae oxygen generator. Coupled with the fuel cell, Chen Xin must keep this survival point.

Qin Lan's delivery time was quite punctual. Although everyone no longer cares too much about time and date in the apocalypse, Qin Lan still delivers the materials that Chen Xin wants at the beginning of each month.

"Axin, your door is well repaired!" Qin Lan couldn't help but praised the shelter's door and entrance, which were completely different from her last visit.

Hearing Qin Lan talking about this, Chen Xin couldn't help but feel a sudden shock. This was the first time he had truly exposed what he had upgraded to in front of others, which inevitably made him a little nervous.

So he asked Qin Lan casually, "Alan, do you feel good?"

"Of course it's very good. Axin, you are doing the construction by yourself. It's amazing to be able to do this. Ordinary construction teams may not be able to do this." Qin Lan didn't seem to notice any violation, but praised Chen instead. New craftsmanship: "I knew you were handy when I was with you, but I didn't expect you to have such a skill, Ah Xin."

"I didn't have a chance to show it before, didn't I?" Chen Xin could only smile right now.

Through Qin Lan's reaction, Chen Xin seemed to understand what the system meant by the vague concept of information state.

For example, the gate of this sanctuary, Qin Lan must be able to see at a glance that this is not something Chen Xin can complete, but the vague concept of the information state of the system makes Qin Lan think that it is Chen Xin's own construction and renovation.

The concept of this information state is vague. It is difficult for Chen Xin to understand what level of technology it is, but it does not prevent him from understanding its effects.

Simply put, it is to make everything reasonable and not let people notice the abnormality.

The upgrade of the sanctuary will make others think that it is a transformation made by Chen Xin himself, and new items will also be considered to be made by Chen Xin himself or bought from where, in short, to make everything reasonable.

Chen Xin didn't know if this was considered a halo of wisdom. After all, this level is only to rationalize the appearance of various items, and it does not reduce wisdom.

For this question, Chen Xin didn't bother too much, and quickly put it behind him.

After moving the supplies brought by Qin Lan into the shelter, Chen Xin still greeted her to sit down and drink water.

Qin Lan didn't refuse. He sat down on the sofa in the living room. After looking around, he suddenly asked Chen Xin, who was pouring water for her, "A Xin, don't you have any heating equipment ready?"

"Heating equipment? Yes, I have prepared an electric heater, and an electric blanket to sleep at night. It should be enough." Chen Xin felt a little surprised when Qin Lan asked him about the heating equipment, but still replied: "I am here. In the mountain, the walls were also insulated when the shelter was built, so the temperature would not be too low, and an electric heater is usually enough."

"Your shelter is so big. There is only one electric heater, which can only heat one place. The whole room is still cold, right? And you are still growing vegetables in your greenhouse. The temperature of the greenhouse can't be too low!" Hearing Chen Xin say this , Qin Lan was still a little worried.
