Replenishing fresh water and expanding the capacity of the water tank, this is a timely help for Chen Xin and solves his urgent needs.

With a water pump that can extract groundwater, Chen Xin obviously doesn't have to use water tightly as before.

Although there were three tons of fresh water and a water circulation system that could purify sewage and recover water vapor in the air, the shelter was not a space station in space. It could not be completely sealed, and the efficiency of water circulation was naturally not 100%. In fact, it was already a very amazing efficiency to be able to achieve a water circulation efficiency of 90%.

But even so, if you lose 10% in one cycle, three tons of water will not last long. According to the water usage statistics of urban residents in Yan Country, under normal circumstances, a person will have to use 130-300 liters of water a day, and the average month is about 4 to 10 tons of water.

And this has not yet calculated the consumption of watering in the planting greenhouse.

Including the evaporation of the water vapor in the ventilation duct and the watering consumption of the planting greenhouse, Chen Xin was able to persist for a month before water shortage was really because he had already saved water.

However, with a water pump and a large water tank that can hold eight tons of water, Chen Xin can let go of it a little while using water. He doesn’t have to live like an astronaut on a space station like before. He washes his face every day and wipes it with a wet towel. He can only wet his body and rub soap after rinsing it clean. If he rinses it, he has to turn off the faucet.

Being able to relax some water usage restrictions is really a great improvement in living conditions for Chen Xin.

He believes that when the survival point is settled tonight, he can increase his daily income by at least 1 o'clock.

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 ground that had not been watered before.

If acre of land is used to grow vegetables, it will be really just a small vegetable garden, not much, but in fact, one hundred square meters is not small at all.

If it were placed in a place like Beijing, Shanghai and Guangzhou, a house of 100 square meters would not be able to be built without a base of one or two million yuan. Do you still think this 100 square meters is small?

Moreover, planting dry rice in 100 square meters may only be enough for Chen Xin to eat it alone, but if you grow cabbage and lettuce, which can be harvested in one month, its yield will be considerable.

At least when Chen Xin harvested all the ripe lettuce and cabbage in the field, he found that there were already a lot of piles on the ground, which made Chen Xin feel that he couldn't finish it.

Chen Xin has no scales for how many of these vegetables are, so it is obviously impossible to count.

But there are at least one or two hundred vegetables, and there are still no calculations for the remaining vegetables and carrots planted on the other half of the land.

Based on eating one vegetable a day, these dishes have been enough for Chen Xin to eat for more than half a year.

Even if the cabbage is resistant to storage and Chen Xin ate cabbage every day, he didn't feel that he could finish the cabbage within half a year, not to mention that there was the same amount of lettuce next to it.

So I left enough part of my food, and Chen Xin planned to take out the remaining items to exchange for supplies.

This is Chen Xin’s original plan. No matter what the outside world is going on, Chen Xin needs to go out and see what the world has become under the impact of a meteorite.

After packing the harvested vegetables in large plastic boxes found, Chen Xin then considered how to deal with these vegetables.

These boxes were storage boxes 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 be packed in the box, so these storage boxes were kept in the storage room, and now they came in handy.

While packing these lettuce and cabbage, Chen Xin also roughly estimated how many vegetables were.

There are about eighty cabbages, which are packed in two plastic boxes, and they look at least three or four hundred kilograms. Although the yield of lettuce on the side is not as exaggerated as that of cabbage, it is also filled with a half plastic box, which looks about two hundred kilograms.

The cabbage grown by Chen Xin is a premature variety. Although the plant is planted for only one month, it grows very full. According to Chen Xin's estimate that one is enough for him to eat for three or five days.

Fortunately, cabbage itself is a resistant vegetable. As long as it is stored properly in a low-temperature environment, it can be stored for three or four months without breaking.

So Chen Xin left a box of cabbage and half a box of lettuce and put it in his own storage room. The remaining two boxes of vegetables were moved to the garage and prepared to take them out to exchange supplies.

But when he moved the cabbage and lettuce to the storage room, Chen Xin scratched his head as he looked at his storage room, thinking that he should also include the upgrade of the storage room on the list of the upgrade plan.

When I was repairing the storage room, because the storage was filled with bottled water and bags of self-heated food, there was no need to store and keep fresh at low temperatures, Chen Xin did not have these functions, and did not prepare a refrigerator in the shelter.

But now these fresh vegetables have been harvested, which has forced Chen Xin to consider the storage of vegetables.

Cabbage is not a big problem, and the storage room is not high, so it should be stored for a long time, but lettuce may become wilted after being stored for a few days.

So it has become Chen Xin’s current concern to find a freezer or refrigerator that can store at least one or two hundred kilograms of vegetables.

Some people may ask, aren’t it said that the temperature outside will drop to minus dozens of degrees Celsius? Are you worried that the vegetables will break down at such a low temperature? Shouldn’t you worry about being frozen and unable to bite?

That's true, but the problem is that the temperature has not dropped to such a low yet!

Moreover, Chen Xin's storage room is inside the shelter, which is located under a layer of soil a hundred meters thick above his head, and it is impossible to be as small as the outside world! If that were the case, Chen Xin would have been frozen and hard long ago.

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

In fact, scientists have calculated that for every 1,000 meters of underground depth, the temperature will rise by 25 degrees. On average, the depth of the strata of every 100 meters will increase the temperature by three degrees.

So now Chen Xin’s shelter is not very cold. The temperature in the container house is still more than 20 degrees. You may not be able to wear a single clothes, but it’s almost the same with a coat.

Of course, this temperature cannot be considered hot. These vegetables may not break quickly when stored in the storage room, but even if the temperature in the storage room is not high, it is still more than ten degrees. If Chen Xin wants to keep the fresh vegetables collected and eat them slowly, it is necessary to prepare a refrigerator or refrigerator.

Fortunately, it is the end of the world now, so it should be fine to take these fresh vegetables out. If you want to change to a refrigerator or refrigerator, you may be able to exchange for a lot of other supplies.

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