Chapter 94

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

"help 4 people to improve their living conditions and get 4 survival points every day"

compared with Mo Qingyan who gave the oxygen generator to Mo Qingyan last time, Chen Xin received the survival point of "doctor" for two days.

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

Without the algae seedlings provided by Chen Xin, it will take some time for the "doctor" to get enough algae for the oxygen generator to work normally.

However, since the survival has arrived, Chen Xin can naturally know that the oxygen generator of "doctor" 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 didn't go out to deliver them to the door.

You know, a trip costs a lot of gas. In the past, it was just gas money. Now gasoline is an important material. Even if he has special police channels, the amount of gas he can change every month will be like his own consumption.

It's OK to go out once in a while and deliver it to people's home, but he can't even afford the generator.

Before the biogas fuel cell is produced, Chen Xinke still relies on gasoline to generate electricity to support the operation of the whole refuge. If he can save gasoline, he can save it.

Chen Xin himself does not go out, but others can come to him to get the goods.

There is no unsalable trend in the two oxygen generators he made. Just as he said on the radio that he had made two more oxygen generators, someone decided immediately.

Today, it happened that the survival of "doctor" had arrived, and the two oxygen generators were also taken.

"Writer, I'm at your door. May I open the door?" Chen Xin was checking the growth of upland rice in the greenhouse. The radio station on his waist rang out a call.

Chen Xin pulled the radio station from his waist and listened to the voice coming from it. He replied, "I know, Laonong. I'll open the door for you."

Seeing that people are already here, Chen Xin naturally can't stay in the greenhouse. After a brief cleaning up, he plans to open the door.

Of course, Chen Xin didn't open the door foolishly. Instead, he went to the bedroom first, felt the pistol out of the weapon cabinet and put it on him.

Even if he had a gun, Chen Xin didn't open the door directly. Instead, he climbed from the passageway in the corridor to a small shelter with a short wave antenna, and took a look at the entrance of the shelter through the gap of the small shelter.

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

There were four doors in a row. After opening three doors, Chen Xin closed the innermost protective door connecting the shelter and the preparation room. Then he put on his gas mask, opened the remaining three doors and walked away.

"The writer!" Seeing Chen Xin open the door and come out, the people in the car jumped down and said hello to Chen Xin.

The person who came to get the oxygen generator is also a member of the survival group, nicknamed "old vegetable farmer", who is usually called old farmer.

His real name is Li Wendong (provided by Shuyou No. 10 of Shuyou group). He used to operate hydroponic cultivation equipment in this city.

When the disaster came, the group discussed how to prepare for the shelter. He also suggested planting greenhouses to ensure food output after the disaster.

After the end of the day, we resumed communication. Chen Xin once heard him mention that he had built a fish vegetable symbiosis system in his refuge, which he envied a lot.

We should know that this disaster can be called the catastrophe of the whole earth's ecosystem. Not only the terrestrial life almost completely disappeared, but the marine and freshwater ecology also collapsed. The fish in Dongting Lake were caught on a large scale long before the disaster.

On the one hand, this is to reserve more edible food, on the other hand, it is also to reduce losses.

However, this batch of fish was not immediately used as food by the municipal government. Instead, it was canned and stored. It is regarded as the strategic reserve of the city.

And this also led to the city now can not eat fish, even if Chen Xin can exchange materials from the special police team, there is no fish.

But this is not a problem for Li Wendong.

His fish and vegetable symbiosis system can provide him with fresh fish as well as vegetables as a normal greenhouse.

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

In the last three or four months after the end of the world, Chen Xinzhen has never tasted any fresh meat, let alone fresh fish.

He took the fresh-keeping box with fresh fish from Li Wensheng. Although he couldn't smell it, he opened it and looked at the ten crucian carp in it. Chen Xin was still satisfied and laughed.

He greets Li Wensheng into the shelter and takes out the oxygen generator from the garage of the servicing room and gives it to Li Wensheng.

"Thank you so much, writer. Your oxygen generator is a real help in the snow!" After taking over the oxygen generator made by Chen Xin, Li Wensheng is busy thanking Chen Xin.Chen Xin looked at him strangely and asked, "old farmer, you have a fish vegetable symbiosis system in your family. Should the oxygen produced by the greenhouse be enough? You can't use an oxygen generator! "

"Writer, don't mention the symbiosis of fish and vegetables. It's hard to say!" Referring to his fish and vegetable symbiosis system, Li Wensheng had a helpless smile on his face: "the fish and vegetable symbiosis system is good, but it consumes electricity! You don't know how much electricity the whole fish vegetable symbiosis system costs to run! "

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

"Of course I did!" The bitterness on Li Wensheng's face was even worse, but he had to explain to Chen Xin: "at first, I thought it was not a big problem as long as there was no electricity in the urban area. As a result, because there was no official shelter in my home, the whole line was out of power.

But it's still within my expectation. 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 current harsh environment, can they? " As soon as Chen Xin heard this, he knew exactly what kind of situation Li Wensheng had encountered.

Speaking of this, Li Wensheng immediately complained: "yes, first acid rain penetrated into the bearing, resulting in power decline and serious wear of the bearing, and then low-temperature freezing rain directly froze the bearing All in all, the trouble is constant. All three wind turbines have been paralyzed in three months. "

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