Doomsday Bunker Upgrade

The fresh water was replenished and the capacity of the water tank was expanded. For Chen Xin, it could be said to be a help in the snow, and it solved his urgent needs.

With a water pump that can pump groundwater, Chen Xin obviously doesn't have to be as tight as before.

Although it has three tons of fresh water and a water circulation system that can purify sewage and recover water vapor in the air, the shelter is not a space station in space. It cannot be completely sealed, and the efficiency of water circulation is naturally not 100%. In fact, To be able to achieve a water cycle efficiency of 90% is already a very impressive efficiency.

But even so, with a loss of 10% in one cycle, three tons of water will not last for long. According to the statistics of urban residents in Yan Kingdom, under normal circumstances, a person will consume 130-300 liters of water a day, which is about a month on average. That's 4 to 10 tons of water.

And that doesn't even count the watering consumption of the growing greenhouse.

Taking into account the evaporation of water vapor from the ventilation pipes and the watering consumption of the greenhouse, Chen Xin was able to persist for a month before the water shortage problem occurred. It is really that he has saved water very much.

However, now that there is a water pump and a large water tank that can hold eight tons of water, Chen Xin can let go of the water a little bit. He doesn't have to live like an astronaut on a space station like before. He washes his face every day with a wet towel and takes a shower. You can only rub soap after you get wet, and turn off the faucet after rinsing.

Being able to release some water restrictions is really a huge improvement in living conditions for Chen Xin.

He believes that when the survival point is settled tonight, the daily income can be increased by at least 1 point.

After filling the water tank, Chen Xin turned off the water pump, and then returned to the planting greenhouse to continue watering, and re-watered the previously unwatered land.

If an hectare of land is used to grow vegetables, it is really just a small vegetable garden. There is not much space, but in fact, 100 square meters is not small at all.

If you put it in a place like Beishangguang, a one-hundred-square-meter house can’t be built without a minimum of one or two million yuan. Do you still think this one-hundred-square-meter is small?

Moreover, the 100 square meters of upland rice may only be enough for Chen Xin to eat, but if you grow vegetables such as cabbage and lettuce, which can be harvested in a month, its yield is considerable.

At least when Chen Xin picked all the mature lettuce and cabbage in the ground, he found that there was a huge pile on the ground, making Chen Xin feel like he couldn't finish it.

How many of these vegetables are there? Chen Xin does not have a scale, so it is obviously impossible to count.

But there are at least one or two hundred vegetables, and the few vegetables that are left to be planted and the carrots planted on the other half of the land are not counted.

According to the calculation of eating one vegetable a day, these dishes are enough for Chen Xin to eat for more than half a year.

Even if the cabbage is durable and Chen Xin eats cabbage every day, he doesn't think he can eat the cabbage in half a year, not to mention there is the same amount of lettuce next to him.

So leave a part that is enough for him to eat, and Chen Xin intends to take out the rest to exchange materials.

And this is also Chen Xin's original plan. No matter what the situation in the outside world is like, Chen Xin needs to go out and have a look to understand what the world has become under the impact of the meteorite.

After packing the harvested vegetables in the large plastic box he found, Chen Xin thought about what to do with the vegetables.

These boxes are storage boxes that I bought before. They were originally used to put things in the shelter, but after entering the shelter, Chen Xin found that there was nothing to pack in boxes, and these storage boxes were kept on hold. In the storage room, it comes in handy now.

In the process of packing these lettuce and cabbage, Chen Xin also roughly estimated how many vegetables there were.

There are about eighty pieces of cabbage, which are packed in two plastic boxes, which seem to weigh at least three or four hundred kilograms. Although the output of lettuce on the side is not as exaggerated as that of cabbage, it is also filled with one and a half plastic boxes, about two It looks like a hundred pounds.

Chen Xin's cabbage is an early-maturing variety. Because the plant is grown in a greenhouse, although it has only been planted for a month, it is also full of growth. According to Chen Xin's estimation, one piece is enough for him to eat for three to five days. .

Fortunately, cabbage itself is a storage-resistant vegetable. As long as it is stored properly in a low temperature environment, it can be stored for three or four months.

So Chen Xin left a box of cabbage and half a box of lettuce and put them in his storage room, while the remaining two boxes of vegetables were moved to the garage, ready to be taken out to exchange supplies.

It was just when he moved the cabbage and lettuce into the storage room, Chen Xin scratched his head while looking at his storage room, and felt that he should include the upgrade of the storage room in the list of the upgrade plan.

When the storage room was being repaired, because all bottled water and self-heating food in bags were stored, there was no need for low-temperature storage and preservation. Chen Xin did not use these functions, nor did he prepare a refrigerator in the shelter.

But now that these fresh vegetables are harvested, Chen Xin has to consider the storage of vegetables.

The cabbage is not a big problem. The temperature in the storage room is not high, so it should be able to be stored for a long time, but if the lettuce is stored for a few days, it may wilt.

Therefore, figuring out a freezer or refrigerator that can store at least one or two hundred catties of vegetables has become what Chen Xin needs to worry about now.

Some people may ask, doesn't it mean that the outside temperature will drop to dozens of degrees below zero? Are you worried that the vegetables will go bad at such a low temperature? Shouldn't you be worried that it's hard to bite?

That's true, but the problem is that the temperature hasn't dropped so low yet!

Moreover, Chen Xin's storage room is inside the shelter. Like the shelter, it is located under the soil layer with a thickness of 100 meters above the head. It is impossible to be as minus tens of degrees as the outside world! If that's the case, Chen Xin would have frozen hard long ago.

The soil layer has a thermal insulation effect, and although the underground geothermal heat is not obvious on the surface, in fact, the heat is continuously transmitted from the mantle to the surface.

In fact, scientists have calculated that the temperature will rise by 25 degrees for every kilometer of underground depth. On average, for every 100 meters of formation depth, the temperature will rise by three degrees.

So now Chen Xin's shelter is actually not very cold. The temperature in the container house is still more than 20 degrees. It may not be able to wear a single coat, but it is almost enough to put on a coat.

Of course, this temperature can't be considered hot. These vegetables are not necessarily bad if they are stored in the storage room, but even if the temperature of the storage room is not high, it is still a dozen degrees Celsius. If Chen Xin wants to harvest these vegetables Save fresh vegetables to eat slowly, it is necessary to prepare a refrigerator or freezer.

Fortunately, it is the end of the world now, and it should be no problem to take these fresh vegetables out, if you want to change a refrigerator or freezer, you may be able to change a lot of other materials.

Thinking of this, Chen Xin began to prepare for going out.
