It is unknown whether Li Wensheng had exchanged for diesel Chen Xin, but after he made another oxygen generator, the materials on hand were also announced to be exhausted. The remaining six group members who needed the oxygen generator could only wait until he obtained new supplies from Qin Lan before he could get the goods.

The other six group members who knew this naturally couldn't hold back. In this case, waiting for one more day will increase the chance of being in danger by one point.

But searching for materials is not an easy task.

Among the materials needed by Chen Xin to make an oxygen generator, glass is the easiest to obtain. After all, if you don’t mind breaking glass, this thing is really everywhere now.

It’s easy to say that if you go to a community where no one lives, you can still get some of it.

It’s just that vacuum pumps and fill lights are not easy to collect. There are two group members who have spare parts for fill lights themselves, but there is really no one who has extra vacuum pumps.

So despite the urgency, except for the "doctor" who was about to get the oxygen generator, Li Wensheng and the other six group members, the other group members 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 can gain 18+16 survival points every day, and his monthly account has exceeded 1,000 points.

Compared with Chen Xin's monthly income of only over 300 points when he first obtained the system, this has improved rapidly.

This also made Chen Xin understand the system's method to obtain daily survival points.

One is naturally the way he is using now, improving his refuge living conditions.

One is to help others and let more people improve their living conditions.

Both have their own advantages and disadvantages, and it is not said that the latter is definitely better than the former. However, one may have a slower survival point, while the other is faster but has certain dangers.

After all, in the disasters of the end of the world, the darkness of people's hearts grows. Whether helping others or harming oneself needs to be grasped.

Therefore, it is more appropriate to help others appropriately, to gain more survival points, and to create a safer and more comfortable refuge for yourself.

Chen Xin, who was finally rich at hand, still couldn't suppress his desire to upgrade and upgraded the kitchen.

The kitchen is a place where Chen Xin considered upgrading when he first obtained the system. The place where induction cookers and kitchen utensils was originally just placed. After Chen Xin upgraded, it was transformed into a formal stove. There was a row of cabinets on the walls, which finally looked like that.

However, the kitchen upgrade did not bring new daily survival points to 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 is said that he can obtain more ingredients and can use the kitchen to cook exquisite and delicious dishes, this can be considered to improve his living conditions.

As for the medical room, because it still lacks some materials, Chen Xin can only wait for Qin Lan to deliver the materials and materials he wants this month before he can upgrade.

Otherwise, he would have to spend 10 times the survival point to upgrade.

Although this is not impossible, Chen Xin still insists on saving as much as possible.

In addition to upgrading the medical room, he also needs to upgrade the power system, which is a big deal.

After all, the power system in Chen Xin's plan must be connected to the biogas fuel cell, and if you want to have biogas, you must first build a biogas tank.

The biogas tank must not be excavated immediately. It can only be obtained by upgrading the algae oxygen generator. In addition, the fuel cell must be kept.

———————————————

Qin Lan's delivery time was quite punctual. Although in the end of the world, everyone no longer cared about time and dates, Qin Lan still delivered the supplies Chen Xin wanted on time at the beginning of every month.

"A Xin, you have a good gate repair!" Qin Lan couldn't help but praise her as she looked at the shelter gate and entrance that had become completely different from the last time she came.

When Chen Xin heard Qin Lan talk about this, he couldn't help but feel a sudden sudden feeling. This was the first time he had truly exposed something that had been upgraded in front of others, which inevitably made him a little nervous.

So he seemed to be inadvertently asked Qin Lan: "Alan, do you think it's good?"

"Of course it's great. A Xin, you can build it yourself and it's already amazing to be able to build it like this. Ordinary construction teams may not be able to do this." Qin Lan seemed to not notice any inconsistency, but instead praised Chen Xin's skills: "When I was with you, I knew you were skillful, but I didn't expect A Xin, you actually have such skills."

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

Through Qin Lan's reaction, Chen Xin seemed to understand what the system means of conceptual vagueness of information state.

For example, the gate of this refuge, Qin Lan can definitely see at a glance that this is not something Chen Xin can accomplish, but the system's information state concept is vague, which makes Qin Lan think that this is what Chen Xin built and transformed himself.

This kind of concept of information state is vague and it is difficult for Chen Xin to understand what level of technology it is, but it does not prevent him from understanding its effect.

Simply put, it is to make everything reasonable and not make people notice abnormalities.

Others will think that the upgrade of the shelter is a transformation made by Chen Xin himself, and new items appear will also think that Chen Xin himself made or bought it. In short, it will make everything reasonable.

Chen Xin didn't know if this was considered a halo of wisdom reduction. After all, at this level, it is just a rationalization of the emergence of various items, and it is not considered a diminishing wisdom.

Chen Xin did not have too much thought about this issue, and quickly left it behind.

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

Qin Lan did not refuse, sat down on the sofa in the living room, looked around, and suddenly asked Chen Xin who was pouring water for her, "A Xin, don't you prepare heating equipment?"

"Heating equipment? Yes, an electric heating stove has been prepared, and there are electric blankets to sleep at night, which should be enough." Chen Xin was a little surprised when he heard Qin Lan ask about the heating equipment, but he still replied: "I am in the mountain. When building the shelter, the walls were also insulated. The temperature will not be too low. An electric heating stove is usually enough."

"Your shelter is so big, with only one electric heating stove, and you can only warm one place. The overall room is still cold, right? And you are still growing vegetables in the greenhouse, so the temperature in the greenhouse cannot be too low!" Qin Lan couldn't help but worry when she heard Chen Xin say this.
