As the village chief, I only raise bugs

Chapter 214 214. Leak
In experiments with mixed metals, the root-knot nematode first enriched gold, then silver, and finally copper.

According to the periodic table of elements, gold, silver and copper belong to group IB elements.

According to the nature of currency, people have used gold, silver and copper as currency since ancient times.

Of the three metals, gold is the most stable, cheapest, but the first to be enriched, and copper is the most active, cheapest, but the last to be enriched.

As for other metals, such as zinc, calcium, aluminum, iron and other metals, Meng Chengwen also conducted experiments, but unfortunately, this root-knot nematode has no feeling for them.

With this feature, Meng Chengwen started experimenting again.

Although it has this effect in the laboratory, it has little effect if it is placed in the application layer.

Because you can't collect it!

You can't collect all this soil and isolate the root-knot nematodes, can you?
If this is the case, it is better to refine the metal directly!
After more than a year of experimentation, he finally found a way to lure root-knot nematodes.

That is to seduce with something aura.

At the beginning, he used light, water, and various chemicals to separate root-knot nematodes according to their characteristics, but the results were not satisfactory. When he was at a loss, he thought of the Peiyuandan and Yiqi he had received from his family. Dan.

These are pills that need to be taken before Xiantian and after Xiantian to increase power. Among them, he has 23 Peiyuan Dans, which are left over from his previous life, and Yiqi Pills, which are only five, because he found the copper mine two years ago. Finally, the family gave him a reward.

However, since his daughter Meng Pinghui did not have the talent for cultivation, he did not let her take it, because it would be of no use if she took it. He was going to put it away, and if any of the descendants had the talent for cultivation, he would pass this pill to them.

After much hesitation, he used a Peiyuan Dan to lure root-knot nematodes. The results showed that although it had a certain effect and could lure out some, there were still many root-knot nematodes in the soil that remained unmoved.

Finally, he gritted his teeth and took out a Yiqi Pill.

When he poured the Yiqi Pill out of the porcelain bottle, the root-knot nematodes in the petri dish rioted like a shark smelling blood, and he easily wiped out the root-knot nematodes.

Later, he tested the range and found that within a range of 100 meters, the Yiqi Pill could attract root-knot nematodes.

This made him very excited. He believed that if this knot nematode was taken out, not only the Meng family, but also the other seven families would be alarmed!
Because this knot nematode represents gold, represents money!

You must know that in this world, gold is found in many places, but in many places, because the grade is too low, the cost of mining is too high to be worth mining.

The root-knot nematode can enrich gold, and because of its short growth cycle, using it to extract gold can save a lot of time, which will definitely be sought after.

Of course, he wasn't going to take the bug out, because he knew that he couldn't keep it.

It would be better to buy the Yiqi Pill in the hands of the young disciples of the major families.

After all, in the current world, it is very difficult to break through to the realm of a flower. Many family children are not willing to practice at all, and they prefer to enjoy this world of flowers.

And Yiqi Pill is a standard material for many Xiantian disciples. If you pay for it yourself, you will definitely buy some of it. You must know that this kind of pill is of no use to ordinary people, and it is not even as good as Peiyuan Pill , at least Peiyuan Pill can hang your life.

And practitioners all have them. Someone once said that as long as 1 yuan, he can sell the Yiqi Pill in his hand.

All that needs to be done now is to find a suitable location.

Although he didn't know where there was gold-bearing soil, besides gold, there was also silver and copper.

Although the prices of silver and copper are not as high as gold, but think about it, the cost of root-knot nematode enrichment is lower. As long as the corresponding plants are planted in places with these elements, and then put in root-knot nematodes, it will continue to generate energy Enrich until the silver and copper content of this place is reduced to an unabsorbable level.

Compared with the output, this input can be said to be much lower.

After figuring this out, he was very excited, which means that he can artificially create a mine!

He is going to do an experiment in the mountains of Yinshan County, because there are many abandoned silver mines there!
Yinshan is located in the southeast of Zhonghe, and it is also an underdeveloped county. It has been famous for its silver production since ancient times, so the name is Yinshan.

This is a high-grade independent silver mine, but with industrial mining, the silver resources here are almost exhausted, and the silver content is reduced to 50 grams per ton, which is abandoned by the mining company.

Due to excessive mining in the past, the land here is also very barren, and there are many abandoned mines, so the economy here is extremely underdeveloped.

The vast majority of people in Yinshan County have gone out to work. A county with a registered population of 40 has a permanent population of less than [-]. It is considered the most desolate county in Zhonghe.

But Meng Chengwen doesn't think so. He believes that even if the silver mine resources here are exhausted, the silver content in the soil and in the mountains will not be low.

He plans to contract some abandoned mines there, and then plant alfalfa with relatively strong enrichment ability, sprinkle root-knot nematode larvae, and when they grow up, use Yiqi Pill to lure the adults and separate silver.

Of course, he will contact the disciples of various schools and buy Yiqi Pills from them.

What needs to be tested now is how long this Yiqi pill can be used, how many knot nematodes it can attract, how much silver or copper it can produce, and then purchase the Yiqi pill based on this.

After figuring this out, he is full of energy, and he feels that a happy life is beckoning to him.

He came to Yinshan County for the first time, and told the people in the county that he wanted to do an experiment and plant in the mountains to see if he could improve the environment here. Yinshan County quickly approved several hilltops for him. The general contract fee for one year is only 1 yuan.

After more than half a year, the crops of alfalfa planted one after another died, but Meng Chengwen's harvest was not much.

After the five Yiqi Pills were used up, he refined a total of [-] tons of silver!

Although some are not pure, but it has reached 98 and up!
He also didn't carry out secondary refining, so after selling it through the precious metal trading company he bought in Yinshan County, he got a total of 400 million!

But the total expenditure is less than 200 million!
The bulk of the expenditure was leveling the road into the mountain. This time it can be used for several years. Except for this road, other expenditures are less than 100 million.

This profit is a bit against the sky!
This year gave him great confidence. He planned to take advantage of the cold weather and the time when crops and root-knot nematodes could not grow, to purchase a batch of Yiqi pills.

But at this moment, Meng Zhengbao leaked his secret, and it was this leak that cost them all their lives!
