Under the night sky, the tribe was quiet and peaceful.

Ye Qiong stayed in his snow cave, still sorting out soil samples. After these samples were numbered, they were placed neatly.

In the absence of modern equipment and instruments, Ye Qiong made several relatively simple conduit testers, and then diluted the soil samples with water. The soil with high mineral content will sink very quickly due to its high density and pass through the filter.

Some small particles can be filtered out.

These are all local methods. Most of them rely on Ye Qiong to test the soil quality with the naked eye and experience, which consumes a lot of energy. Because the soldiers brought back many samples, Ye Qiong can only analyze them bit by bit. If the analysis fails,

If you don't, you will miss some rare mineral resources.

Now Ye Qiong's priority is to screen iron ore and coal mines.

The importance of iron ore is unquestionable. The weapons in the tribe require high-quality iron ore to be refined, especially the giant crossbow, which consumes a lot of iron. The crossbow body, giant arrows, and gears all consume a lot of iron.

of iron.

Coal mines are the resources Ye Qiong wants to find most right now. As long as they find coal mines, the tribe will obtain new energy, which will have a huge boost to the overall strength of the tribe.

After studying the soil quality for two days, Ye Qiong marked the soil quality where iron ore and coal mines are likely to occur. There are three locations in total. Judging from the content, the possibility is higher.

After these two days of research, Ye Qiong has gained something else, that is, he found a sample with relatively fertile soil, and marked this sample separately. After the spring of next year, Ye Qiong is going to try it to see if he can grow anything.

.

Ye Qiong has collected a lot of edible fruit tree seeds in the past two years. In the past, when they were migrating, these seeds were of little use because it would take at least two years from the time they were planted until the fruit can grow.

Two years on the snow star are forty-eight months...

If the seeds are planted during the migration, it will benefit those who come after you.

Now that he has decided to settle down and develop, Ye Qiong must let the tribe enter the most primitive farming era in the shortest possible time.

It would be great if we could find crops like corn and barley that can be harvested within a few months. After all, the long eighteen months of winter will not bring any crops to life. They can only be harvested at the beginning of spring.

Sow seeds and harvest before autumn.

As for Ye Qiong's imminent need for lime, he still has no clue. The good news is that Ye Qiong found a piece of soil that is very sticky and seems to be a temporary substitute for lime. If a volcano can be found in the future, it will be replaced.

Three days later, Ye Qiong personally led a team of twenty people on the road to collect clay soil. After running for two days and one night, they arrived at the soil collection location.

This is a small hillside, backed by the Dinglong Mountains. Below it is a dry river. When there is abundant rain in the summer, a huge river will be formed. With the arrival of winter, the upstream water source will dry up, and this place will become a dry river.

After Ye Qiong arrived, he was pleasantly surprised to find a lot of sand. If you are lucky, there is a high probability that this kind of river will yield gold!

Although gold has no role on this planet for the time being, and is not even useful for humans to burn wood for heating, Ye Qiong knows very well how useful gold is!

It can be said to be the core force of technology. On the earth in Ye Qiong's previous life, gold has been directly used as currency since ancient times. The arrival of the technological era has allowed the true role of gold to be reflected, that is, CPU!

As a very stable metal, gold must be used to connect the wafer and the board. In the technological era when Ye Qiong was alive, there was no substitute!

Although gold is now found, it is of no use to Ye Qiong and the entire Snow Star, but it must be stored. Its unique stability can play a supporting role in Ye Qiong's research later.

On both sides of the river, the content of clay soil is very high. Ye Qiong arranged for half of the people to collect clay soil and the remaining half to collect sand. He himself, who was more interested in gold, took Daidai along the river.

The upper stream walked up.

There is an idiom called "Big Waves Washing the Sand".

What is the purpose of scouring the sand?

Find gold!

Why is there gold in the river?

In fact, the reason is very simple, because gold is a very stable substance and does not react chemically with other substances. Many stones contain trace amounts of gold. These stones will crack into sand and gravel under long-term weathering.

, and the metal elements will condense into small granular gold sand.

After countless years, heavy rains and storms, and the convergence of rivers, the water will accumulate the golden sand together. These golden sands of different sizes will slowly sink with the river and then be buried underground.

As the saying goes, when meeting water, gold will be born, this is the truth.

Ye Qiong and Daidai quickly ran far away, and after groping along the way, they discovered that there was indeed gold in the river!

But the content was not much, and it was sparse. Ye Qiong dug with his bare hands for a long time, and together with Daidai, because there was no filter, he could only find some very fine gold sand.

This discovery made Ye Qiong very excited. There was gold sand in the river, which proved that there was a gold mine in the upper reaches. It seemed that Ye Qiong had to make plans as soon as possible. He decided on the location of the gold mine first and then occupied it, so as not to be occupied in the future.

If other tribes occupy it, there will be other troubles.

How to occupy it is a question, how to protect it is a question, how to mine it is also a question, and how to utilize it is the ultimate question.

These questions gave Ye Qiong a headache just thinking about them. It was precisely in response to those words...

You have great ambitions in your heart, but you have no one around you who can help you!

It seems that we need to find ways to train talents as soon as possible.

After wandering for a while, Ye Qiong came back with Daidu with him. Daidai's bear paws were now black. He wiped them in the snow and rolled a few times before carrying the bear on his back.

Ye Qiong returned to the team.

This time, two carriages were brought out. The soldiers had loaded the two carriages fully. Ye Qiong looked at the sky and decided to return.

Now that there is clay and sand, Ye Qiong needs to continue to study the proportions of the combination. After reaching a similar level, he will lead the tribe to start doing big things!

Build stone walls!

Now the tribe covers an area of ​​less than one square kilometer, about the size of a dozen football fields together.

More than a thousand people were crowded into such a big place.
Chapter completed!
