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

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

Compared to the last time he handed the oxygen generator to Mo Qingyan, he immediately obtained a survival point, Chen Xin waited for two days before receiving it.

Of course, the reason is that he did not help install it at home like he did to Mo Qingyan, and also provided a bottle of algae seedlings.

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

However, since the survival point has arrived, Chen Xin naturally knew that the "doctor" oxygen generator has started to operate normally.

In the past two days, Chen Xin was not idle. He used the materials at hand to make two more oxygen generators, but he did not go out to deliver the goods to his door.

You should know that it costs a lot of oil to travel. In the past, it was just gasoline, but now gasoline is an important material. Even if he has the channels of the special police force, the gasoline he can get every month will be a little more than his own consumption.

This little gasoline is okay to go out occasionally, and it will deliver goods to people at home, but he will not even be able to provide a generator.

Before the biogas fuel cell was produced, Chen Xinke still had to rely on gasoline to generate electricity to support the operation of the entire shelter, saving as much gasoline as possible.

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

The two oxygen generators he made were not at all unsalable. He just said on the radio that he had made two more oxygen generators, and someone immediately ordered them.

Today, the "Doctor"'s survival point was arrived, and someone came to collect these two oxygen generators.

"Writer, I'm at your door. Can I open the door?" Chen Xin was planting a greenhouse to check the growth of dry rice. A call sounded from the radio station hanging on his waist.

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

Seeing that someone had arrived, Chen Xin could not be still in the greenhouse. After tidying up for a while, he planned to open the door.

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

Moreover, even with the gun, Chen Xin did not open the door directly. Instead, he climbed from the passage in the corridor to a small bunker with short-wave antennas, and took a look at the door of the shelter through the gaps in the small bunker.

Seeing that there was indeed only one car and there was no other person in the car, Chen Xin climbed back along the passage and then started to open the door.

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

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

The person who came to get the oxygen generator was also a member of the survival group, nicknamed "Old Vegetable Growing Farmer". Everyone usually called him an old farmer.

His real name is Li Wendong (provided by book friends and book friends), and he originally operated hydroponic cultivation equipment in this city.

When the disaster came, the group discussed how to prepare a shelter. He also suggested that everyone build greenhouses to ensure grain output after the disaster.

After the end of the world, everyone resumed communications, and Chen Xin once heard him mention that he had created aquaponics symbiosis system in his sanctuary, and he was very envious of this.

You should know that this disaster can be called the catastrophe of the entire earth's ecosystem. Not only are the land creatures almost completely extinct, but the oceans and freshwater ecology also collapsed. The fish in Dongting Lake were 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 to reduce losses.

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

This also leads to the fact that the city can no longer eat fish. Even if Chen Xin can exchange supplies from the special police force, there will be no fish.

But this is not a problem for Li Wendong.

His aquaponics system can provide vegetables like a normal greenhouse, but also provide him with fresh live fish.

This time, the price of Li Wensheng's exchange for the oxygen generator from Chen Xin was ten fresh fish.

This is very rare in the end of the world. If you think about it carefully, Chen Xin has never tasted a bite of fresh meat in the past three or four months after the end of the world, let alone fresh fish.

He took the fresh-fill box containing fresh fish from Li Wensheng. Although he couldn't smell it, after opening it, Chen Xin still smiled with satisfaction when he looked at the ten crucian carp handled inside.

He called Li Wensheng into the shelter, carried the prepared oxygen generator out of the garage in the garage of the decoration room and handed it over to Li Wensheng.

"Thank you so much for the writer. Your oxygen generator is such a timely help!" After taking the oxygen generator made by Chen Xin, Li Wensheng hurriedly thanked Chen Xin.

Chen Xin looked at him strangely and asked in confusion: "Old farmer, your home has a fish and vegetable symbiosis system. The oxygen produced in the planting greenhouse should be enough? You shouldn't be able to use the oxygen generator!"

"Writer, don't mention the symbiosis of aquarium, that thing is hard to describe!" When talking about his aquarium symbiosis system, a helpless smile appeared on Li Wensheng's face: "The aquarium symbiosis system is good, but it consumes electricity! You don't know how much electricity the entire aquarium symbiosis system is running!"

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

"Of course I've considered it!" Li Wensheng's face became even more bitter, but he had to explain to Chen Xin: "At the beginning, I thought that as long as the city was constantly powered, it would be no big problem. As a result, the entire line of my house was no longer powered because there was no official shelter.

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

"Wind turbines? They can't cope with the harsh environment in this place, right?" Chen Xin knew what kind of situation Li Wensheng had encountered when he heard it.

Speaking of this, Li Wensheng suddenly felt resentful: "Yes, first the acid rain penetrated into the bearing, causing the success rate to decrease, the bearing was seriously worn, and then the low-temperature freezing rain directly freezes the bearing... In short, there are constant troubles. All three wind turbines were paralyzed in three months."
