Chapter 1575 Mutual Transactions

After all, the fish they got through the bamboo baskets these days were alive, and there were indeed too many of them to eat all at once.

So, they also began to seriously consider whether it was possible to make a small pond specifically for fish farming?

This is actually still a bit difficult, and there are three main issues to consider-water storage, oxygen, and water change.

Oxygen and water change are actually one and the same. If the water can be changed automatically, it will naturally provide enough oxygen in the water.

As for the problem of water storage, it can also be solved barely, that is, using clay to make a more waterproof material.

With this in mind, although the two were not completely sure, they also planned to give it a try.

Anyway, there was nothing to do recently, and neither gathering nor hunting could proceed normally, so they could just make more attempts.

The two dug a large pit about 1m to the right of the stream, with an area of ​​about two square meters, roughly a 1×2 rectangle.

Even if it is to make a reservoir, it will not be too big, 2㎡ is about the same.

After the four walls and the bottom of the 2㎡ reservoir are all scraped flat, you can start to apply a waterproof layer, that is, clay.

Mix clay and plant ash to form a product similar to cement, and then evenly apply it on the surrounding walls and the ground, so as to achieve a certain waterproof effect.

In fact, the effect is not particularly good, and it cannot reach the level of cement, but the two people's requirements cannot be too high, just barely usable.

After about a day of drying, the clay is dry, and there are some slight cracks, so the two people applied another layer to improve the waterproof effect as much as possible.

After repeating this three times, the water storage has taken shape, and then the two people began to make a water exchange system.

How can water be changed naturally?

The two people's idea is very simple, open a hole in front of the reservoir and a hole in the back.

The water from the upstream flows down and connects to the hole above the reservoir. The river water will directly flow into the reservoir, and then flow out through the hole below, thus forming a water exchange effect.

But in order to prevent the fish from escaping from the cave, a net bag made of bamboo is woven at the entrance of the cave, which can only allow water to flow through but not allow fish to swim through.

In this way, the reservoir can operate normally, and the fish caught can be put into it and kept for a long time.

And because there is new stream water replenishment every moment, even if there is leakage, the problem is not really big.

Afterwards, the two of them spread some stream stones in the reservoir to increase the beauty and water storage level, and also help the fish form an environment more suitable for their lives.

In the next few days, they also put the harvested fish into the reservoir to see the effect of the reservoir and found it very good.

Fish can survive in such an environment and will not swim away.

In this way, the two can obtain fish food for a long time, which can be regarded as the development of aquaculture.

Qi Yuan was also quite amazed after seeing this scene, which is the development of civilization.

It only takes a short month to use the knowledge in his mind to move from primitive society to agricultural civilization, and he can live in this wilderness for a long time.

Moreover, as time goes by, their farming and breeding will become more and more developed, controlling more and more food and breeding more and more animals.

The originally scarce food will become more and more abundant and sufficient with the development of planting and breeding. This is the transformation of nature by humans.

The development of planting and breeding took almost a month for the two people.

Now it has been more than a month since the end of the cold wave.

It has been 7 months since they came to this game world, which is more than half a year.

Recently, after Bai Hao and Huang Hai finished their work in the reservoir, they also received the first message from other survivors on the radio.

In fact, the two were a little surprised. They didn't expect to receive the first message after such a long time. Originally, the two thought that there should be a lot of survivors around.

But now it seems that there are very few survivors in the surrounding 50km area.

Perhaps there are some survivors, or they may have received their messages, but they just don't want to contact other survivors, so they didn't reply.

The two didn't know the specific situation. Whether they received the first message now or made them very happy.

In fact, from Qi Yuan's perspective, it can be clearly seen that there are two survivors in the 50km range around the two of them.

However, they are both women, and they are all developing alone, so they have a strong sense of prevention and do not respond to the information received on the radio casually.

The message that was replied recently was from two survivors who migrated from other places. They responded immediately after receiving the message.

These two survivors, like Bai Hao and Huang Hai, are in a situation of cooperation, so they are bolder and willing to respond to the information of other survivors.

After a brief exchange between the two parties, although they were vigilant, they finally decided to contact each other.

It is a very rare thing to be able to meet other survivors in the wild environment.

Although the total number of humans is very large, the number of humans surviving in this game world is actually not much now.

Because the game world is large enough, only a small number of people can get together. It is also a kind of fate to meet each other.

After a brief discussion, the two sides agreed to meet each other and exchange the daily necessities they need.

Through the radio, the two sides chatted with each other privately, so they also knew each other's resources.

Bai Hao and Huang Hai have a lot of bamboo baskets, bamboo baskets, and bamboo baskets, as well as a lot of fish, shrimps, and snails.

The other two survivors have a lot of fruits and some daily herbal medicines.

The resources owned by both sides are different, so they can exchange with each other.

The two agreed to meet at the interface of the area about 5km away from the camp. This area is very safe and the travel is relatively fast.

Then after the agreement, they directly selected a day and determined to meet at noon.

This is also unavoidable, because everyone has to start in the morning and then go to the agreed place, and it is almost noon when they get there.

If there are some accidents on the road, it may be later.

Fortunately, both parties are very punctual, and they officially met at around 1pm the next day.

Bai Hao was in the open, while Wang Hai was hiding in the dark with a bow and arrow. Soon, two women were seen coming from a distance. They should be the two survivors who agreed to meet this time.
