Wei Xuan now has a lot of insulation materials in his hands, and he should be able to find more when he wanders around the city in the future. But even so, he had to have a suitable place to store the ice to be collected.

There is a basement in the community, and there will be a full floor under each building. But the area of ​​each basement is not large, because there is only one floor of space, but it needs to be allocated to each household in the whole building, so the area cannot be increased naturally.

What's even worse is that these basements all have a small part on the ground. On that part of the wall, every room in the basement has a small window like a slit. This alone is a very easy place for ventilation and air leakage in summer. problem lies in.

If it is possible, Wei Xuan really wants to dig a big hole to make a storage room, but how deep should it be? How to ensure the ventilation inside after digging? And how can you ensure that people will not leak it when they step on it?

"Well, if it doesn't work, we can only use polyurethane foam to block the windows and seal the inside with steel plates to insulate the temperature." Wei Xuan scratched his hair, thought for a while and decided that it would be easier to transform the basement into an ice cellar, at least He didn't have to worry about digging a big hole with great difficulty, but in the end the whole hole completely collapsed into a real hole.

Although if the basement is used instead, it would be a waste of steel plates if each room is remodeled separately, but who knows that if all the basements are opened up, it is likely to cause instability and failure of the room?

After studying Wei Weixuan, he found that things were not as simple as he thought at first, so he pondered for a while and decided - wait until he goes out to find some books.

It is true that he has never learned knowledge about architecture, but he can always find some related books in bookstores in the urban area, right? Even if you can't find it in a small bookstore, there will always be one in a big bookstore, right? Even if there are no big bookstores, at worst, he can go to some universities in city t to look for it - city t is not a small city, there are quite a few universities before the end of the world, and two of them are 211 , 985, there is always a school with related majors.

Considering that he still has time to go to the lunatic's place in a few days, Wei Xuan decided to take Du Hang to look for a relatively large bookstore at that time, and then think of other methods if he really can't find it.

Put this matter aside for the time being—the steel plates and the tanks filled with polyurethane foam are placed in the community, and they will not break down for a while, let alone run away. Wei Xuan decided to deal with other things first.

Getting up and going to the living room, followed by the obedient Du Hang, Wei Xuan went to the planter and took a closer look, and couldn't help showing a gratified smile on his face - some of the grains he had planted before had obviously been completely destroyed. matured.

The growth of mature plants is similar to that before the end of the world. At this time, crops such as rice and peanuts have completely turned golden yellow. Wei Xuan actually obtained a lot of books related to agriculture before. Now, after researching the introduction of these crops, he can confirm that many crops have become very different from before.

Some of the crops that borne on them became significantly smaller in size, some of them became very strange in shape, some of them grew a little bigger, and there were still a few that looked the same as before in terms of size.

But one thing is the biggest difference between these crops and the previous crops - their growing season has obviously become a lot longer than before. Leaving aside those who are not yet mature, at least the harvest period of rice is obviously much slower than before. Wei Xuan remembers that this thing can be planted at least twice a year before the end of the world. If the climate in the south is relatively good and the planting machine is planted at the set temperature, it is reasonable to say that three crops a year are no problem, but now More than half a year has passed, and they have just matured.
