"Helping other people's shelters improve their living conditions and gain 100 survival points."
"Help 4 people improve their living conditions and gain +4 survival points every day"
Compared with the last time when he handed over the oxygen concentrator to Mo Qingyan and received survival points immediately, Chen Xin waited for two days to receive the survival points from the "doctor" family.
Of course, the reason was that he did not help with the installation like 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 some time for the "doctor" himself to obtain enough algae for the oxygen concentrator to start working normally.
But now that the survival points are in his account, Chen Xin can naturally know that the "doctor's" oxygen concentrator has begun to operate normally.
In the past two days, Chen Xin was not idle. He used the materials on hand to make two more oxygen concentrators, but he did not go out to deliver them to the door again.
You must know that a trip costs a lot of gas. In the past, it was just gas money, but now gas is an important commodity. Even if he has the channels of the SWAT team, the gas he can exchange every month will be about the same as his own. Consumption is a bit larger.
With this small amount of gasoline, it was okay to go out for an occasional run and deliver goods to people's doors, but he couldn't even afford 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. Gasoline could be saved as much as possible.
Chen Xin himself doesn't go out, but others can come to him to get goods.
The two oxygen concentrators he rushed out were not unsalable at all. He just said on the radio that he had made two more oxygen concentrators, and someone immediately placed an order.
The "doctor's" survival points happened to arrive today, and someone also came to pick up these two oxygen concentrators.
"Writer, I'm at your door. Can you open the door?" Chen Xin was inspecting the growth of upland rice in the greenhouse when a call came from the radio hanging on his waist.
Chen Xin pulled the radio off his waist, listened to the voice coming from inside, and responded: "I know, old farmer, I'll open the door for you right now."
Seeing that someone had already arrived, it was naturally impossible for Chen Xin to stay in the greenhouse. He simply tidied up and planned to open the door.
Of course, Chen Xin didn't open the door stupidly. Instead, he went to the bedroom first, took out the pistol from the weapons cabinet and put it on his body.
And even with the gun, Chen Xin did not open the door directly. Instead, he crawled through the passage in the corridor to the small bunker where the shortwave antenna was placed, and looked at the entrance of the shelter through the gap in the small bunker.
Seeing that there was indeed only one car, and it didn't look like there was anyone else in it, Chen Xin crawled back along the passage and started to open the door.
There were four doors in a row. After Chen Xin opened three doors, he closed the innermost protective door that connected the interior of the shelter and the maintenance room. Then he put on a gas mask, opened the remaining three doors and walked away.
"Writer!" Seeing Chen Xin open the door and come out, the people in the car jumped out and greeted Chen Xin.
The person who came to get the oxygen concentrator was also a member of the survival group, nicknamed "the old vegetable farmer", and everyone usually called him the old farmer.
His real name is Li Wendong (provided by Book Club No. 1), and he originally ran hydroponic planting equipment in this city.
When the disaster struck, the group discussed how to prepare for the shelter, and it was he who suggested that everyone build a greenhouse to ensure food production after the disaster.
After the apocalypse, everyone resumed communication. Chen Xin once heard him mention the aquaponics system he had built in his shelter, and he was quite envious of it.
You must know that this disaster was a catastrophe for the entire earth's ecosystem. Not only was land life almost completely extinct, but the marine and freshwater ecology also collapsed. The fish in Dongting Lake had been fished on a large scale long before the disaster.
On the one hand, this is to be able to store more edible food, and on the other hand, it is also to reduce losses.
However, the city government did not use this batch of fish as food immediately. Instead, it was canned and stored as a strategic reserve for the city.
This has also resulted in the city now having no fish to eat. Even if Chen Xin could exchange supplies from the SWAT team, there would be no fish.
But this is not a problem for Li Wendong.
In addition to providing vegetables like a normal greenhouse, his aquaponics system can also provide him with fresh live fish.
This time, Li Wensheng exchanged the oxygen concentrator from Chen Xin for ten fresh fish.
This is very rare in the apocalypse. If you look carefully, in the three or four months after the apocalypse, Chen Xinzhen has not tasted a bite of fresh meat, let alone fresh fish.
He took the fresh fish box from Li Wensheng. Although he couldn't smell it, after opening it and looking at the ten crucian carp prepared inside, Chen Xin still laughed with satisfaction.
He greeted Li Wensheng into the shelter, took out the prepared oxygen concentrator from the garage of the maintenance room, and handed it to Li Wensheng.
"Thank you so much, writer, your oxygen concentrator is a real help in times of need!" Li Wensheng hurriedly thanked Chen Xin after taking over the oxygen concentrator made by Chen Xin.
Chen Xin looked at him strangely and asked in confusion: "Old farmer, your home has an aquaponics system. The oxygen produced by the greenhouse should be enough, right? You shouldn't need an oxygen concentrator!"
"Writer, don't mention aquaponics, it's hard to explain in just one word!" When mentioning his aquaponics system, Li Wensheng had a helpless smile on his face: "The aquaponics system is good, but it consumes electricity! You don’t know how much electricity the entire aquaponic system consumes!”
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 have considered it!" The bitterness on Li Wensheng's face became even more intense, but he had to explain to Chen Xin: "At first, I thought it would not be a big problem as long as there was no power supply in the urban area. But in the end, my area was completely destroyed because there was no official shelter. The lines are out of power.
But this is still within my expectations. I took this into consideration when I built the shelter, so I specially prepared three wind turbines. "
"Wind turbines? They can't cope with the harsh environment now, right?" When Chen Xin heard this, he knew what kind of situation Li Wensheng had encountered.
Speaking of this, Li Wensheng suddenly felt resentful: "Yes, first the acid rain penetrated into the bearings, causing a decrease in power and serious wear of the bearings, and then the low-temperature freezing rain directly froze the bearings... In short, the troubles continued, and the three wind turbines He was completely paralyzed within a few months.”
The resentment in Li Wensheng's words made Chen Xin immediately understand the dilemma he was facing at this time. (End of chapter)
