Chapter 1575 Mutual Transactions
After all, the fish they got through the bamboo baskets 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 the main issues to consider are 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 reluctantly, that is, using clay to make a relatively waterproof material.
With this in mind, although the two people are not completely sure, they also plan to give it a try.
Anyway, there is nothing to do recently, whether it is gathering or hunting, it can not proceed normally, so it is just right to make more attempts.
The two people 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 water reservoir, it will not be too big, 2㎡ is enough.
After scraping the four walls and the bottom of the 2㎡ water reservoir 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 requirements of the two people are not too high, and it can be used barely.
After about a month of drying, the clay is dry and there are some cracks, so the two people apply another layer to improve the waterproof effect as much as possible.
After repeating this several times, the water storage has taken shape, and then the two people start to make a water change system.
How to change water naturally?
The two people's idea is very simple, open a hole in the front of the water reservoir and a hole in the back.
The water from the upstream flows to the hole above the reservoir, and the river water will directly flow into the reservoir, and then flow out through the hole on the other side, thus forming the effect of changing water.
But in order to prevent the fish from escaping from the hole, a bamboo net bag is woven at the hole to only allow water to flow through, but not let the fish swim through.
In this way, the reservoir can operate normally, and the fish caught can be put into it to be raised for a long time.
And because there is new stream water replenished every moment, even if there is water leakage, the problem is not really big.
After that, the two 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 living.
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 live in such an environment, and they 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 impressed after seeing this scene. It was the development of civilization.
It only took a short month to use the knowledge in his mind to move from primitive society to agricultural civilization. He lived in this wilderness for a long time.
And 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 two months.
For example, 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 of the time.
Recently, after Bai Hao and Huang Hai finished their work at 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. They originally 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.
Maybe there are some survivors who may have received their messages, but they just don't want to contact other survivors, so they didn't reply.
The two don't know the specific situation. Whether they received the first message or made them very happy.
In fact, from Qi Yuan's point of view, it is clear enough to see that there are two survivors in the 50km range around them besides them.
It's just that they are all women, and they are all developing alone, so they have a strong sense of prevention and don't respond to the messages received on the radio casually.
The message that was replied recently was from two survivors who migrated from other places. They replied immediately after receiving the message.
These two survivors, like Bai Hao and Huang Hai, are in a situation of two-person cooperation, so they are relatively brave and willing to respond to messages from other survivors.
After a brief exchange between the two sides, although they were both cautious, they finally decided to make contact.
It is a very rare thing to be able to meet other survivors in the wild environment.
Although the total number of species is very large, there are actually not many species that survive in this game world.
Because the game world is large enough, only a small number of people can get together. Meeting each other is also a kind of fate.
After a simple 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 sides 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 date and decided 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 might be even later.
Fortunately, both parties are very punctual. At about 1:00 pm on the second day, the two parties officially met.
Bai Hao was in the open, while Wang Hai hid 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 this time.
