Doomsday Bunker Upgrade

In the power distribution room of the shelter, the second uncle and several elders all stood at the door, watching with anticipation as Chen Xin directed two young people who knew electricians to connect the isotope thermoelectric battery he removed from the car to the shelter. circuit.

"Okay, as long as the red and blue wires are connected, the power generation and service life of this battery are enough to supply the entire shelter for more than ten years." Chen Xin watched two distant relatives connect the battery with a circuit connection cable. After receiving the transformer of the power distribution box of the shelter, he nodded affirmatively to the second uncle and the others.

"Can this really meet the electricity requirements? Just such a small battery?" An elder obviously couldn't believe it. After all, the isotope thermoelectric battery that Chen Xin brought was really inconspicuous.

It is beyond the imagination of these elders who have only cultivated the fields all their lives.

On the other hand, Chen Xin's father was more accepting of this, and asked Chen Xin, "What is the output power of this battery? How high is the voltage?"

"500V voltage, 150KW output power, this is the battery for my car, there is no big problem to meet the needs of the shelter." Facing his father's question, Chen Xin answered seriously: "The voltage is a bit high. , it must be connected to a transformer before it can be used, and there is a certain danger, so you need to pay special attention when using it. However, it is not a big problem. After that, I will upgrade and optimize the circuit and adjust the access method. There will be no problem. ."

Hearing Chen Xin say this, Chen Xin's father calculated it, and then said to the second uncle: "The power is a bit low, but it is enough for heating, that is, when using other high-power electrical appliances, pay attention, there may be insufficient power. ."

"It's good to be able to turn on the heating, and there are other high-power electrical appliances in the village." The second uncle heard what Chen Xin's father said, and immediately looked happy, and didn't care what Chen Xin's father said. The problem of not turning on more high-power electrical appliances.

However, Chen Xin also heard what his father said, thought about it and said, "This is not a problem, I made this battery myself, and I can change one with a car battery. When you come back, second uncle, you can find two cars in the town. When the battery comes, I can replace it with a battery pack, so there is no problem, and the production capacity on the greenhouse side can also be expanded a bit.”

This is also something in Chen Xin's plan, like his own shelter, to increase the production capacity of the greenhouse and obtain more output, so as to exchange for more materials and form a virtuous circle.

"Can greenhouses increase production capacity?" Second uncle was particularly concerned about this. As the village head of the village for many years, and a farmer who has cultivated land for a lifetime, he is the most sensitive to the issue of crop output.

Chen Xin nodded and answered affirmatively: "Yes, after the electricity comes up, the supplementary lights and heaters in the greenhouse can work for a longer time, thereby speeding up the growth of crops and obtaining higher yields. And I plan to Modify the structure of the greenhouse, and strive to allow you to have a variety of food here."

Chen Xin's remarks immediately made the elders present happy. For them, being able to order more food is more realistic than anything else.

"The relationship is good, and it's a good thing to have more food! You have food in your hands, so don't panic." The second uncle's face was flushed with joy, which was completely different from the full face when Chen Xin came back and saw him for the first time. different.

Chen Xin didn't make any bookings, just nodded and said nothing. He only had an idea about the transformation of the greenhouse, and he had to read it first.

As for now, the second uncle and the others can't wait to turn on the heating equipment in the shelter.

As the heating equipment was turned on, the temperature in the shelter finally rose, and everyone had a smile on their faces.

On Chen Xin's side, he also received a system prompt after a long absence:

"Help others to improve their living conditions and get 5000 survival points"

"Help multiple people improve their survival conditions and get +50 survival points every day"

The population of the village is of course more than fifty people, but the increase in survival points that can be obtained by a single improvement of the living conditions of a shelter is only so much.

For the current Chen Xin, these gains are gratifying, but it is not that he is particularly concerned about it, and more importantly, this method can bring him income.

Thinking that he has provided isotope thermoelectric batteries to the country, Chen Xin can't help but look forward to how many survival points it can bring to himself if the country promotes this technology.

Even if a sanctuary only has fifty points, under the large base of so many sanctuaries in the country, this is an astronomical amount of income.

The only thing Chen Xin is worried about now is whether the isotope thermoelectric batteries produced by others under his influence can be recognized by the system, so as to bring himself a living point.

Chen Xin is not sure about this issue, but it is not a big problem. Even if the isotope thermoelectric battery produced by others is not recognized by the system, he can produce it himself and sell it to others.

This kind of thing that is just needed will inevitably become hard currency as long as the country starts to promote it, and there will be no worries about sales.

And as Chen Xin can provide more products, he can harvest more survival points. After all, although the harvest of survival points can only be harvested once, there are too many places that a shelter can improve. He can cut one crop after another just like cutting leeks.

——————————————————

The greenhouse in this sanctuary in the village is completely different from that of Chen Xin. Although it is also a greenhouse, the area here is obviously much larger.

And Chen Xin could see that this greenhouse should have been transformed after adding a cover to the original farmland, instead of transporting the soil into the shelter from the outside as farmland as he did.

But even so, the area of ​​arable land is limited. According to the introduction of the second uncle, the area of ​​arable land here is only about one and a half mu, a total of 900 square meters.

This 900-square-meter land is like a huge nine-square grid. There are four thick support columns in the center of the greenhouse, and there are twelve same support columns on the walls to support the top span beam.

900 square meters of farmland sounds like a lot, and the output is not bad, but considering that there are more than 100 people in the village, the output is not too much. After all, this greenhouse is not like Chen Xin’s own. Fill lights and heaters can be turned on 24 hours a day.

The greenhouse with only one layer of soil is not like the multi-layered greenhouse that Chen Xin has upgraded. It can realize three-dimensional planting and obtain greater yield.

The types of crops planted in the field are also relatively simple, only cabbage, radish and a large leaf crop that Chen Xin does not know.

"Second Uncle, what is this planted?" Chen Xin walked over to the leaf crops, looked at the vines and leaves that were almost all growing close to the ground, and asked the Second Uncle curiously.

"This is a sweet potato. It's been planted for almost four months, and it's ready to be harvested." Referring to these crops, the second uncle's face was also full of pride and satisfaction. As he said, he had grain in his hand. Don't panic.

For the farmers of the Yan Kingdom, these harvest crops are the biggest source of happiness.

When Chen Xin heard that the second uncle said this kind of sweet potato, he suddenly showed a surprised expression: "Is this a sweet potato?"

"Huh? Ah Xin, haven't you seen sweet potatoes?" The second uncle was a little puzzled, things like sweet potatoes should be very common, and Chen Xin probably hasn't seen them before.

Chen Xin shook his head, reached out and touched the vines and leaves of these sweet potatoes and said, "Of course I have seen sweet potatoes, but I have never seen the sweet potato vines and sweet potato leaves growing in the ground."

Hearing Chen Xin say this, the second uncle nodded understandingly. It is true that many people have eaten sweet potatoes, but not everyone knows sweet potato vines and sweet potato leaves.

"Do you have a greenhouse yourself? Would you like to bring some sweet potatoes back home? This kind of thing is very easy to grow. A sweet potato can be used as a seed after being chopped up." The second uncle thought that Chen Xin also had a greenhouse, and immediately suggested to him. .

When Chen Xin heard what the second uncle said, he didn't refuse. He stood up and said, "Then I will trouble the second uncle. Although I have a lot of seeds, I really don't have any sweet potatoes."

"That's a trivial idea, but what kind of staple food do you grow there? You can't just grow vegetables, and you won't be able to fill your stomach just by eating vegetables." The second uncle expressed concern about Chen Xin. Obviously, in his opinion, the staple food is not enough. to be planted.

Chen Xin had no problem with this, and replied with a smile: "I grow upland rice, which is more than enough for me to eat by myself, plus there are a lot of vegetables, I can get a lot of food in exchange. I am a city after all. , the food is much better than at home."

When the second uncle heard what Chen Xin said, he nodded and turned to him and asked: "A Xin, I'm relieved if you say that, then look at what can be modified in this greenhouse to increase the output. It's a good thing, so that the villagers can also have a little more to eat."

This is what the second uncle is most concerned about and looking forward to. More than half of the greenhouse in front of us is planted with sweet potatoes, and the growth of sweet potatoes takes at least five to seven months, even for short-lived sweet potatoes, it takes four months. Before harvesting The villagers can't talk about how full they are.

"I'll take a look first. I just have an idea on how to transform it. I have to read it for details." How to do it? My idea is to add a layer of hydroponic planting, which can produce a lot of crops."

Hearing Chen Xin say this, the second uncle couldn't help but be a little worried: "Hydroponic planting? Is this thing easy to do? I have heard of this technique, but no one in the village has done it!"

"This technology is not complicated, second uncle, listen to me..." Chen Xin laughed and introduced hydroponic planting technology to second uncle.
