Chapter 1568 Still Cold

But even if they go out now, they can't go too far away from the camp, and they work around the camp.

They mainly do two things.

The first thing is to continue to burn charcoal. For a long cold winter, it is not too much to prepare more charcoal.

Moreover, there are still a lot of wood that has not been burned into charcoal piled around the camp. It is necessary to deal with it.

The second thing is that they plan to dig a new shelter.

This also surprised Qi Yuan a little. He didn't expect that they would build a shelter again at this time.

And it seems that they made a temporary decision.

While the two used the charcoal fire to keep warm, they cleaned the snow around the original shelter, about seven or eight meters away, and then started digging down.

This time, they did not plan to build a shelter on the ground, but to build a shelter underground, similar to a cellar.

After listening to their conversation, Qi Yuan roughly understood their ideas.

The two thought about it for a long time in the shelter and felt that they needed to open a new way out for themselves. They couldn't just sit at home and wait for death.

Because no one knew how long the cold wave would last, and they couldn't guarantee that the food they stored would be able to survive the entire cold wave.

So they needed to take precautions to prevent the situation where one day their food was finished but the cold wave had not passed.

In order to deal with this situation, it became very necessary to develop the planting industry, but in the original shelter, the space was very limited, and there was no remaining space for them to grow crops.

On the contrary, a lot of soil would make the shelter dirty, and their original life became worse.

So the two thought of digging an underground shelter, which was specially used to grow crops and store charcoal.

And the two also checked and found that the soil around the camp was very solid, which was convenient for digging and not easy to collapse, and they had all the conditions to dig an underground shelter.

The two did it as soon as they said it. Anyway, there was no condition to go out now, so they stayed in the camp to dig an underground shelter.

What the two didn't expect was that they were very lucky. They refreshed the one-key digging artifact-shovel in the survival store on the second day.

And the price is only five survival coins. After some ideological struggle, the two gritted their teeth and bought it.

In this way, the speed is obviously much faster. In just a few days, it has taken shape.

According to the two people's ideas, they dug about 5 meters.

The entire shelter is three meters underground, and the underground shelter itself is more than 2 meters high, so it is just 5 meters.

The two can clearly feel that when they are 5 meters underground, the temperature is not so cold. Obviously, the insulation effect of the soil is still very good.

When the depth is reached, they start to dig horizontally and dig out the main body of the entire shelter. It must be said that the soil here is very good. There are not many rocks. It is all pure soil, which is relatively easy to dig.

And so far, there is no sign of collapse, and the overall structure is very strong.

However, for safety reasons, after digging a few square meters of area, the two still moved some wood from the camp and used it as a pillar in the underground shelter.

It can greatly improve safety and avoid unexpected situations.

After that, because they were working completely in the underground shelter, the temperature increased a lot and could be maintained at around 4~5℃, and the working environment was obviously much better.

The two continued to dig and expanded the entire underground shelter to about 20㎡.

In fact, it is entirely possible to continue to expand and make the area of ​​the entire underground shelter larger, but after thinking for a long time, the two stopped their actions.

Because the area of ​​20㎡ is almost enough, even if the area is larger, they don’t have more seeds to sow.

More importantly, although the shelter looks very solid now and there is no risk of collapse, it does not mean that it is foolproof. Every additional 1㎡ of space means that the risk of collapse will be greater.

For safety reasons, the size is only maintained at about 20㎡.

If there is insufficient space in the future, it is highly likely that it will not continue to expand, but will dig another underground shelter. Anyway, it is not particularly difficult. With the ability of two people, digging a few more is not a problem.

This is the advantage of having more people, which is far from as simple as 1+1=2. If one person wants to dig such a shelter, it will take at least ten or twenty days.

But if two people cooperate with each other, it only takes 1/3 of the time, and helping each other can avoid many accidents and reduce the error rate.

After digging out this underground shelter, the first thing the two did was not to move the crops immediately, but to build a fireplace and ventilation ducts.

Connect the underground shelter to the ground, and then use clay to make a fireplace. Maybe they will live there in the future, so the fireplace will be more suitable.

Next to the fireplace, five or six bamboos were tied together to make a ventilation duct. The temperature difference between hot and cold is conducive to the conduction of air and ensure that there is enough oxygen in the underground space.

After doing this, the two breathed a sigh of relief and began to transfer the crops in.

Since there is this underground shelter, there is no need to plant crops in bamboo. Not only is the scope small, but the growth difficulty is also high, which is conducive to the development of crops.

So, they directly reclaimed the land in the underground shelter, and then planted these crops in rows, mainly planting some staple foods, such as rhizomes, potatoes, and cassava.

Relatively speaking, it is also the easiest crop to grow. At least it is easier to survive than wild vegetables and beans, and the cost performance is higher than ginger and shallots.

In a limited range, these cost-effective crops must be planted.

In a space of 20 square meters, these crops are planted in about 15 square meters. It’s not that the two don’t want to plant more, but the seeds are really not enough. Most of the food has been dried and stored, and only a small part is used for seeds.

This made the two regret it a little. If they had known earlier, they would have left more.

But there is no way. If they could have thought of building an underground shelter earlier, perhaps their life would be more comfortable now, and they would be more likely to plant more crops.

But the two did not regret it too much. Planting crops is a matter of certain risks.

No one can guarantee that these crops will eventually mature. There is a great possibility that they will fail in the end and no food will be grown.
