Ding Ning lived in Mo Qingyan's shelter, also saw Chen Xin's shelter, and was caught by his father and returned to the official shelter. During the days when he returned to the police station, he also saw other shelters in the city. He naturally had some understanding of the living conditions of these shelters after the end of the world, and also had a sharp contrast.

When it comes to comfort, it is naturally Mo Qingyan’s shelter ranked first.

Although the shelter built before the disaster was not designed to deal with this disaster, all living facilities and conditions were very complete, and after years of careful management by Mo Qingyan, she naturally felt comfortable living.

However, when Mo Qingyan built this underground shelter, it was mainly designed for short-term shelter, and the plan was to spend about one to three years with reserve materials.

Therefore, her shelter lies in her ability to maintain herself, which is about equal to nothing.

As for the abundant supplies, it is still an official refuge.

Although it is the end of the world, all materials have become scarce and precious, the official shelter has the state reserved materials before the disaster, and there are various response measures planned in advance after the disaster. In addition to the overall material allocation and planning of the country, the official shelter can indeed be said to have everything at present.

But the official shelter is only about how to live. As for whether you live comfortably and whether you eat well, you have already retreated to a secondary position and only consider these when everyone survives and has the spare time.

It's like in the ice car era. Setting up a tent first allows unruly people to live in, and then consider slowly upgrading their houses to deal with the severe cold.

Chen Xin's shelter is indeed not as comfortable as Mo Qingyan's shelter. In terms of accommodation conditions, the shelter where container-style houses are buried in the mountains are not excellent.

However, in this kind of doomsday, it is already a very lucky thing to have such a place to live. Some small shelters in the city are not doing well in preventing cold. Although the temperature inside is not too hot to live in, they still have to wear cotton coats.

And the most important thing is that Chen Xin’s shelter has a greenhouse that can produce food.

This is a very important point, because only a self-sustaining refuge can protect the survival of survivors in such a harsh environment that may last for decades or even hundreds of years.

Otherwise, relying solely on material support, how long can the amount of materials you reserved be used without replenishment?

"Axin, what are you relying on to generate electricity now? Is gasoline enough? Is it enough? If not enough, I will ask my dad to exchange supplies for you for more." Ding Ning asked Chen Xin, who had just thought of this question: "Your shelter is good, but it's a pity that energy is a problem. If the oil is burned out, you will have a power outage."

Thinking of this, Ding Ning also became interested and said to Chen Xin: "Why do I turn around and tell my dad that I can get you a diesel generator! Diesel is more resistant to storage than gasoline, so you can also use it for a longer time."

"Thank you for your kindness, but I have a solution." Chen Xin did not tell Ding Ning that he planned to make algae oxygen-generating power generation and biogas fuel cells.

These are all upgraded later with the help of the system. It is difficult to explain before the upgrade. After the upgrade, there is no need to explain the information state of the system, so Chen Xin simply is too lazy to say it.

As for the diesel generator that Ding Ning said he wanted to help him get, although the diesel generator is better than the gasoline generator in terms of efficiency and energy consumption, on the one hand, this little improvement is not very meaningful to Chen Xin, who has the system. On the other hand, he really has no place to get another diesel storage tank.

———————————————————

Since Ding Ning has sent the materials, Chen Xin can also start working on Mo Qingyan to make an algae oxygen generator.

Compared to the one he had rubbed by his hands before, the oxygen generator Chen Xin made for Mo Qingyan was much richer in materials.

At least he no longer had to wrap pipes with mismatched diameters and tie them with tape. In the materials sent by Ding Ning, there were pipes and joints of various diameters.

However, when he made his own oxygen generator before, because the materials were simple and they didn't need to be made very fine, Chen Xin just used the tools on the weapon workbench to make do with it.

Now I want to make an oxygen generator for Mo Qingyan. Chen Xin looked at the glass that Ding Ning brought for him, and thought about it and still wanted to make a workbench.

After all, it is okay to use the tools on the weapon workbench, but it is more suitable to use professional workbenches, such as processing glass, connecting pipes and welding circuits.

"Fortunately, Xiao Ding sent a lot of things this time." Chen Xin smiled at the door of the storage room and looked at the various things Ding Ning sent inside.

Find a few boards from the storage room, nail them together as a table and countertop, and then place tools on it. A simple workbench is considered to be made up.

When Chen Xin used to decorate this kind of workbench before and when he was repairing a shelter, he had met with workers doing decoration.

A three or two boards are made of a table, which is also a countertop for processing. It is very simple, but it is more convenient and practical.

As long as tools and equipment are added, it will be a very useful tool table.

After the work was done, Chen Xin did not examine and inspect too much. He just opened the system and looked at the upgrade materials, and spent 20 survival points to upgrade the workbench.

The upgraded workbench immediately changed its appearance. The structure that was originally nailed up by a few wooden boards turned into a stronger table. A layer of green rubber pads were also laid on the countertop, and there was an additional hanging board behind the countertop like the weapon workbench.

But what is different from the hanging boards of the weapon workbench is that the hanging boards of the workbench are full of tools, while the tabletop is clean, leaving a lot of space.

Looking at the workbench in front of him, Chen Xin sat down on the stool in front of the workbench and tried the feel of the countertop. The smooth and flat countertop immediately gave Chen Xin the urge to do something immediately.

However, although the workbench is satisfactory, Chen Xin made the workbench in the garage, which undoubtedly made the not-so-spacious space in the garage look much narrow and crowded.

This made Chen Xin scratch his head. It is natural to upgrade the garage and expand the area or simply separate the workbench as a studio, but Chen Xin must consider the consumption of resources, especially the investment of the survival point.

"Now, let's upgrade the defense of the gate first." Chen Xin sat in front of the workbench, took out his notebook, looked at the recorded information and murmured to himself: "Maybe you can add a garage and defense room to the gate when upgrading the gate, move all the cars and things for going out, and prepare to set off at the gate like in the game..."
