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

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

Compared with the last time he handed over the oxygen concentrator to Mo Qingyan and immediately obtained the survival point, Chen Xin waited for two days to receive this survival point from the "doctor's" family.

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

Without the algae seedlings provided by Chen Xin, it would take a little time for the "doctor" to get enough algae to get the oxygen concentrator to start working properly.

However, now that the survival point has arrived, Chen Xin can naturally know that the oxygen concentrator of the "doctor" has begun to operate normally.

In the past two days, Chen Xin has not been idle, and has made two oxygen concentrators with the materials at hand, but he has not gone out to deliver them to the door again.

You must know that it costs a lot of fuel to run a trip, which used to be nothing more than gas money, but now gasoline is an important material, even if he has the channel of the SWAT team, the gasoline he can get every month will be a little larger than his own consumption.

It's okay to go out for a run with this gasoline once in a while, and even deliver it to someone's door, but he can't even afford a generator.

Before the biogas fuel cell was developed, Chen Xinke still had to rely on gasoline power generation to support the operation of the entire shelter, and gasoline energy was saved.

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 have any unsalable tendencies at all, and he just said on the radio that he had made two more oxygen concentrators, and someone immediately set them.

Today, it just so happened that the "doctor's" survival point arrived, and these two oxygen concentrators were also picked up.

"Writer, I'm at your door, can I open the door?" Chen Xin was inspecting the growth of upland rice in the planting greenhouse, when the sound of a call sounded in the radio hanging on his waist.

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

Seeing that people had already 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 did not open the door directly stupidly, but went to the bedroom first, took out the pistol from the weapon cabinet and put it on his body.

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

Seeing that there was indeed only one car, and there was no one else in the car, Chen Xin climbed back along the passage and began to open the door.

After opening three doors in a row, Chen Xin closed the innermost protective door connecting the inside of the shelter and the maintenance room, and 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 down and greeted Chen Xin.

The person who came to get the oxygen concentrator was also a member of the survival group, nicknamed "Old Vegetable Farmer", and everyone usually called him Old Farmer.

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

When the disaster struck, the group discussed how to prepare the shelter, and he also proposed that everyone plant greenhouses to ensure food production after the disaster.

After the apocalypse, everyone resumed communication, and Chen Xin once heard him mention that he had built a fish and vegetable symbiosis system in his shelter, and he was quite envious of this.

This catastrophe is a catastrophe for the entire earth's biosphere, not only the almost complete extinction of terrestrial life, but also the collapse of marine and freshwater ecology, and the fish in Dongting Lake were fished on a large scale long before the disaster.

This is partly to be able to stock up on a little more edible food, and on the other hand, to reduce losses.

However, this batch of fish was not immediately used as food, but was made into canned food and stockpiled, which can be regarded as a strategic reserve of 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 will be 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 growing greenhouse.

And this time, Li Wensheng exchanged the oxygen concentrator from Chen Xin for ten fresh fish.

This is very rare in the last days, and if you think about it, in the three or four months after the end of the world, Chen Xin really hasn't tasted a bite of fresh meat, let alone fresh fish.

He took the fresh-keeping box containing fresh fish from Li Wensheng's hand, although he couldn't smell it, but after opening it, he looked at the ten crucian carp processed inside, Chen Xin still smiled with satisfaction.

beckoned Li Wensheng into the shelter, and took out the finished oxygen concentrator from the garage of the maintenance room and handed it to Li Wensheng.

"Thank you so much to the writer, your oxygen concentrator is really a charcoal in the snow!" After taking over the oxygen concentrator made by Chen Xin, Li Wensheng hurriedly thanked Chen Xin.

Chen Xin looked at him a little strangely, and asked puzzledly: "Old farmer, your family has an aquaponics system, and the oxygen generated by the planting greenhouse should be enough, right?" You shouldn't be able to use an oxygen concentrator! ”

"Writer, don't mention aquaponia, that thing is hard to describe!" When it came to his aquaponics system, a helpless wry smile appeared on Li Wensheng's face: "The aquaponics system is good, but it consumes electricity!" You don't know how much electricity the whole aquaponics system uses to operate! ”

Hearing Li Wensheng's complaint, Chen Xin couldn't help but raise his eyebrows and asked him: "Old farmer, didn't you consider the energy consumption of this system before you built it?" ”

"Of course I thought about it!" The bitterness on Li Wensheng's face was even worse, but he had to explain to Chen Xin: "At first, I thought that as long as the urban area was uninterrupted, it would not be a big problem, but as a result, the entire line of my house was out of power because there was no official shelter.

However, this was still expected by me, and I took this into account when I built the shelter, so I specially prepared three wind turbines. ”

"Wind turbines? They can't cope with the harsh environment they have now, can they? As soon as Chen Xin heard this, he knew what kind of situation Li Wensheng had encountered.

Speaking of this, Li Wensheng suddenly became angry: "Yes, first the acid rain seeped into the bearing, causing a decrease in power and serious wear of the bearing, and then the low-temperature freezing rain directly froze the bearing...... In short, the trouble continued, and the three wind turbines were all paralyzed in three months. ”

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