Doomsday Bunker Upgrade

"Help others to improve their living conditions and get 100 survival points"

"Help 4 people improve their survival conditions and get +4 survival points every day"

Compared to the last time when he handed over the oxygen generator to Mo Qingyan and immediately obtained the survival point, Chen Xin waited two days to receive the survival point from the "Doctor"'s house.

Of course, the reason was that he didn't help with the door-to-door installation as he did to Mo Qingyan, and also provided a bottle of algae seedlings.

Without the algae seedlings provided by Chen Xin, it would still take a little time for the "doctor" to obtain enough algae for the oxygen generator to start working normally.

However, since the survival point has been received, Chen Xin can naturally know that the oxygen generator of the "doctor" has begun to operate normally.

In the past two days, Chen Xin has not been idle either. He made two oxygen generators with the materials at hand, but he did not go out to deliver the goods to the door.

You must know that a trip will cost a lot of oil. In the past, it was nothing more than oil money. Now gasoline is an important material. Even if he has access to the SWAT team, the gasoline he can get every month will be like his own. Consume a bit more.

It’s okay to go out for a run with this little gasoline every now and then, and even deliver it to someone’s door, but he can’t even supply a generator.

Before the biogas fuel cell was developed, Chen Xinke still had to rely on gasoline to generate electricity to support the operation of the entire shelter.

Chen Xin doesn't go out by himself, but others can come to him to get the goods.

The two oxygen concentrators he rushed out did not tend to be unsalable at all. He just said on the radio that he had made two more oxygen concentrators, and someone immediately ordered them.

Today, the "doctor"'s survival point just arrived, and the two oxygen generators were also picked up.

"Writer, I'm at your door, can you open the door?" Chen Xin was checking the growth of upland rice in the greenhouse when a call rang from the radio hanging on his waist.

Chen Xin tore the radio from his waist, listened to the voice inside, and responded, "I know the old farmer, I'll open the door for you."

Seeing that someone had come, Chen Xin naturally couldn't stay in the greenhouse, so he simply cleaned up and planned to open the door.

Of course, Chen Xin didn't just open the door stupidly, but went to the bedroom first, took out the pistol from the weapon cabinet and put it on his body.

And even with the gun, Chen Xin did not open the door directly, but climbed from the passage in the corridor to the small bunker with the short-wave antenna, and glanced at the door of the shelter through the gap of the small bunker.

Seeing that there was really only one car, and it didn't look like there were other people in the car, Chen Xin then climbed back down the aisle, and then started to open the door.

After four doors in a row, Chen Xin opened three doors, but closed the innermost protective door connecting the interior of the shelter and the preparation room, then put on a gas mask, opened the remaining three doors and walked away.

"Writer!" Seeing Chen Xin open the door and walk out, the people in the car hurriedly jumped out and greeted Chen Xin.

The person who came to get the oxygen generator is also a member of the survival group, nicknamed "Old Vegetable Farmer", and everyone usually calls him an old farmer.

His real name is Li Wendong (provided by Shuyouqun Shuyou Shihao), and he originally operated hydroponic planting equipment in this city.

When disaster strikes, the group discusses how to prepare for the shelter, and he also suggested that everyone build a greenhouse to ensure food output after the disaster.

After the apocalypse, everyone resumed communication, and Chen Xin once heard him mention that he had created an aquaponics system in his shelter, and he was quite envious of this.

You must know that this disaster is a catastrophe for the entire earth's ecosystem. Not only did terrestrial life almost completely die out, but the marine and freshwater ecology also collapsed in a complete mess, and the fish in Dongting Lake had been caught on a large scale long before the disaster.

On the one hand, it is to be able to reserve a little more edible food, and on the other hand, it is to reduce losses.

However, this batch of fish market was not immediately used as food, but was made into canned food and stored as a strategic reserve for the city.

And this has also led to the fact that the city can no longer eat fish. Even if Chen Xin can exchange supplies from the SWAT team, there is no fish.

But this is not a problem for Li Wendong.

His aquaponics system provides him with fresh live fish in addition to vegetables like a normal greenhouse.

This time, the price Li Wensheng exchanged for the oxygen generator from Chen Xin was ten fresh fish.

This is very rare in the apocalypse. After careful calculation, in the three or four months after the apocalypse, Chen Xinzhen has never tasted any fresh meat, let alone fresh fish.

He took the fresh-keeping box containing fresh fish from Li Wensheng. Although he couldn't smell it, after opening it and looking at the ten crucian carp that had been processed inside, Chen Xin still smiled with satisfaction.

Greeting Li Wensheng into the shelter, he took out the ready-made oxygen generator from the garage of the preparation room and handed it over to Li Wensheng.

"Thank you so much to the writer, your oxygen generator is really helpful!" After taking over the oxygen generator made by Chen Xin, Li Wensheng hurriedly thanked Chen Xin.

Chen Xin looked at him strangely, and asked inexplicably, "Old farmer, your family has an aquaponics system. The oxygen produced by the greenhouse should be enough, right? You shouldn't need an oxygen generator!"

"Writer, don't mention aquaponics, that thing is hard to describe!" When he mentioned his aquaponics system, Li Wensheng's face showed a helpless and bitter smile: "Aquaponics is good, but it consumes electricity! You don't know how much electricity the whole aquaponics system runs on!"

Hearing Li Wensheng's complaint, Chen Xin couldn't help but raised his eyebrows and asked him, "Old farmer, before you built this system, didn't you consider its energy consumption?"

"Of course I thought about it!" Li Wensheng's face was even more bitter, but he had to explain to Chen Xin: "At first, I thought it would not be a problem as long as there was no electricity in the city, but the whole area of ​​my house was completely destroyed because there was no official shelter. The line is out of power.

However, this is still within my expectations. I took this into consideration when I built the shelter, so I specially prepared three wind turbines. "

"Wind generators? They can't handle the harsh environment now, right?" Chen Xin knew exactly what kind of situation Li Wensheng had encountered.

Speaking of this, Li Wensheng was suddenly full of resentment: "Yeah, first, acid rain infiltrated the bearings, causing power drop and serious bearing wear, and then the low-temperature freezing rain directly froze the bearings... In short, the troubles continued, three wind turbines He was completely paralyzed in three months."

The resentment in Li Wensheng's words made Chen Xin immediately understand the dilemma he was facing at this time.
