The temperature has dropped again.

Zhou Shuangshuang took off the thermometer at the door, it was almost noon, and the temperature was only two degrees.

The heavy leaf curtain was lowered, and Zhou Shuangshuang shrank back.

In this big "yurt", the ground is covered with leaves and grass stems layer by layer, thick and soft, more than a normal mattress, it is really not bad at all, and there are neatly stacked colorful quilts on it.

In fact, only the inside of these quilts is filled with cotton, and the workmanship of the quilt outside is quite poor, and there are a lot of big holes and small holes-

It can't be helped.

Zhou Shuangshuang was too anxious, Zhai Xing and Xu Honglin were familiar with the garment factory, but this was ...... The time was too rushed, and they only had time to contact a manufacturer waiting to resell and pull back the quilts that had been piling up in the warehouse for an unknown number of years.

Seriously, the price of this quilt is cheaper than a cotton coat.

However, Zhou Shuangshuang's original idea was to help them survive the winter, whether this quilt can be used for a long time, she also has two plans in her heart.

…………………………

The sky light fell overhead, and the slightly cool air blew in from the top of the canopy, so that the tightly wrapped room did not feel dull at all.

And the trunks that are the supports, I don't know what kind of species they are - they have been cut down for a while, but not only do they not look dry and cracked, but they are sending out buds from the branches one after another!

- Oh my God!

Zhou Shuangshuang sighed: This prehistoric creature is like this...... Strong?

In this kind of weather, primitive people only wear clothes sewn from leaves when they go out every day - the new clothes are so beautiful that they are reluctant to do so.

And this trunk also has such a vigorous vitality......

Now, she doesn't have to worry about the stability of this house—maybe it's all rooted underground!

By next year, if the roof of the house has not been damaged by the growing branches, it will probably be the strongest building it has ever been.

………………………………

Zhou Shuangshuang looked at the time, it was almost time to eat.

There were five large stone mortars evenly distributed around it, and a raging flame was dancing inside. Above the flames, the edge of the stone mortar was also stuck with great difficulty, and huge stone cauldrons were erected.

The bottom edge of the cauldron is irregular, so that the flame below can still contact the air and burn vigorously.

Above the large stone mortar in the center, thick branches pierced the belly of the unknown animal, and were placed on the flames to roast fiercely, and the fragrant grease gradually dripped off.

"Poof" fell into the fire, causing the flame to leap upwards by two points.

At this time, the three wounded who had not fully recovered from the body who remained here walked out of the door and looked at the sky - it was time.

They greeted Zhou Shuangshuang, and began to clumsily and carefully take out a stone jar from the simple wooden box on the side, which was provided by Zhou Shuangshuang, the fine salt of the white flowers.

Fine salt was evenly sprinkled in the pot, and stacks of simple wooden bowls were also pulled out of the box.

As for chopsticks...... They are still not used to chopsticks, at this time, it is more convenient to use their hands.

Zhou Shuangshuang did not force this.

This is originally an era when Ru Mao drank blood and everything was still in its infancy, and it was impossible to force them to follow the living habits of modern people, and it would also affect them.

- This point, Zhou Shuangshuang has gone through several worlds, and he has already understood it quite well.

…………………………

As for the rock salt they collected, it was not wasted, and it was still stored well, waiting for the winter to pass, and used to marinate meat.

- Zhou Shuangshuang also learned later that fine salted meat is always not as good as coarse salt. It's just that in reality, because of the popularization of science and technology, everyone doesn't have a lot of cured meat, and they all eat it before it goes bad, so no one specifically asks for this.

Of course, people who live by this craft are all clear in their hearts.

But Zhou Shuangshuang's only cooking skills were all practiced with Lu Feng in the last days, so how do you know?

Even if she checked the information, she had read it roughly, and she couldn't tell the difference between the coarse salt and the fine salt in the information.

So, after settling down and studying all the information she had obtained, she taught everyone to still collect rock salt slowly.

- In the early tribal exchanges, food, weapons, and salt were all very important strategic materials.

This is still the case even thousands or even thousands of years later.

…………………………

Primitive man did not have the concept of laziness.

They are a large collective, and private ownership has not yet emerged, and everyone is used to working together and harvesting together.

Even if they are wounded, when they can't go to work with everyone, they will do their best, study what Zhou Shuangshuang brought over, and try to imitate and learn.

For example, the box that is not tight, and the jar that is taken out of the stone, and the stone mortar, the cauldron......

Without metal, this is all the same.

And now, Zhou Shuangshuang followed the tutorial and learned to make the simplest bow and arrow in the tent, and those pregnant women and wounded who were inconvenient to go out were picking up their stored meat on the side.

The temperature in the room was too high, so they put the meat frozen by the cold in the corner, and then learned to cover it with layers of leaves, and then weave a large wall of leaves to separate them—

Also, there is no fire on that side.

……………………

Because the house is really big, even if there is such a simple storage room, there is still a lot of leeway, and Zhou Shuangshuang also deliberately took a thermometer to test -

When the outside temperature is at its highest, there is still unthawed, hard meat.

And the broken fur was carefully sewn up by them and spread on the ground, specially adding an extra layer of quilts to pregnant women and the wounded—

When Zhou Shuangshuang saw this, she immediately sighed-

They're too smart.

And the progress is really fast.

When the soup in the heavy stone pot began to "gurgle" and bubble, people who had gone out to work also came back one after another.

Now they have a house, they have warm clothes, and they have enough food, but their task is still very difficult.

……………………

The original cave could not be abandoned, there was also a fire burning there, and the originally damp and soft floor and walls were separated by wooden sticks, divided into patches, and in them, plants were planted that were picked out by Zhou Shuangshuang and did not require so much temperature and light.

- Although the cave is not ventilated enough, the ground is soft and damp, and with the brazier and heavy leaf door, although it is still inhabitable, but a little remodeling, isn't it a natural greenhouse?

Floors, walls, you can all plant!

Regardless of whether they can successfully bear fruit or not, Zhou Shuangshuang feels that in the case that they cannot stay for a long time, after these practices, at least, they will learn to grow by themselves.

With their cleverness, as soon as they start, they will form a new mode of survival on their own.

——This is also what Zhou Shuangshuang wants to see the most.
