Here, Yun Hao began to make every effort to promote the "Yun's Salt Making Method" in Linhai County, and there was also good news from the silver mine, saying that the silver mine was a rich ore and had great mining value.

After getting the definite news, Yun was also ready to start mining silver mines.

But mining silver is not an easy task.

The first thing is that the Yun clan has to report to the empire, the Dali Empire is not allowed to mine veins casually, first-class nobles are only allowed to mine veins after the empire has passed the review, and private mining veins are not allowed at all, and the Yun clan sends personnel to Xinping, the imperial capital, and it takes at least nearly three months to go back and forth.

Of course, it is impossible for the Yun clan to sit like this, under normal circumstances, the empire will allow first-class nobles to open mines, so the Yun clan has to make some preparations in advance, such as building or widening the road to the silver mine, recruiting miners, preparing tools, etc., all of which require the Yun clan to invest a lot of money.

So the Yun clan sent people to Xinping day and night to carry out the preparations before the silver mining, but Yun Yi, who stayed in Yunfu leisurely, had a new idea in his mind because of the silver mine.

Don't look at whether it is Yunhua County or the outside world, they call Yunhua's fiefdom as Yunhua "County", and what is implemented on paper is also Yunhua County, in fact, Yunhua County is not qualified to be called "County" at all, Yunhua County has the name of "County", there is no "County", and the most important reason why others regard it as a "County" is that the territorial area of Yunhua County reaches or even exceeds the area of ordinary counties.

In fact, whether it is the Dali Empire or other countries on the land of Shenzhou, the biggest criterion for dividing counties is the local population.

If the population exceeds 20,000, there can be a county, and if the population exceeds 200,000, there can be a county, and there are about 10 counties within a county.

The area of Yunhua County is medium in the counties of the Dali Empire, but the total population of Yunhua County is only more than 90,000, and the counties under it can only be regarded as three.

Yunhua County can have a population of more than 90,000 or the Yun family's ancestors have worked hard for two hundred years, when Yunhua County first became the Yun fiefdom, the total population of Yunhua County was only a few thousand, from a few thousand to ninety thousand, this is already a huge progress, after all, Yunhua County has many mountains and forests and poor land, which cannot attract a large number of people to settle down.

Yunhua County is the fief of the Yun family, so when people call the Yun family, they are often preceded by the word "Yunhua", Yunhua Yun has been closely linked together, Yunhua County is the largest heritage of the Yun family, although Yunhua County is vast, but the population is seriously insufficient, which is a huge defect for the Yun family.

The population background is lower than that of a family family, and the innate martial artists in the family can only ensure that the family can continue to pass on to a certain extent, if the population of a family is large enough, then the family can follow and defend itself.

The innate martial artist is very strong, but he can't rob an army of a thousand people, and an army of a thousand people can kill the innate martial artist at a huge price, so in this world, the innate martial artist cannot represent everything, and a person who is strong cannot walk sideways on the land of Shenzhou.

But it is different to have enough population base.

The population of Yunhua County is only more than 90,000, and the Yun clan can pull out an army of more than 5,000 people at any time, with a limit of 15,000 people.

However, the population of Yunhua County is still too small, if the population of Yunhua County can reach 200,000 or 300,000, how many troops can the Yun clan arm? If the troubled times come, the Yun clan can also rely on enough troops to maintain the Yun clan's foundation, and even participate in the struggle for world dominance.

What Yunyi wants to do is to increase the population of Yunhua County.

The Yun clan is about to build roads to mine silver mines, which will require a lot of manpower.

The Yun clan treats the people under its rule well, so there are basically no beggars in Yunhua County, and there are even fewer cases of starvation, and the residents of Yunhua County can basically eat enough.

In this case, Yun Yi felt that the manpower used by the Yun clan to build roads and open mines did not need to be recruited in Yunhua County, but to continue to recruit outside Yunhua County, and it was best to recruit those tenants who did not have land at home to rent other people's land for a living, and the recruited workers must move their entire families to Yunhua County, and the Yun clan could issue a certain settlement fee, and one gold coin per household was too much.

The Yun family needs at least 3,000 workers to build roads and mine silver mines, which is 3,000 families, more than 10,000 people, which can make the population of Yunhua County break through the 10,000 mark, not to mention that the Yun family itself still has a lot of money in storage, even the salt industry that broke out in Linhai County can also bear the relocation costs of 3,000 families.

Now it is only a silver mine, and there will be various minerals such as copper ore, iron ore, and coal mine waiting to be mined in the future, and the number of workers that Yunshi needs to hire is more than 15,000, then the total population of Yunhua County will increase by more than 50,000, which is of great significance to Yunhua County, which has a population of only 90,000.

As the annual income of the Yun clan increases, the additional money at your disposal increases, and spending a certain amount of money increases the population base of the Yun clan, which is very cost-effective.

Yun Yi summarized his views and wrote them down on paper, and then asked Xu Bo, the housekeeper of Yun Mansion, to personally send them to his third uncle Yun Yuankai.

It didn't take long for Yun Yi's handwriting to appear in Yun Yuankai's hand, and seeing that it was sent by his nephew that day, Yun Yuankai opened the letter with a serious expression and read it carefully.

Yun Yuankai was more and more surprised, he didn't expect his nephew to have such a big picture, why didn't he think of it?

And in the letter, Yun Yi also used war as an example, this is the first time that Yun Yi showed a trace of his ambition in front of his elders, two lives, Yun Yi will not be willing to let the Yun clan only be in Yunhua County.

After reading the letter, Yun Yuankai fell into deep thought.

In Yun Yuankai's opinion, Yun Yi is a qualified patriarch, and he can think of things that none of their elders have noticed, if it is really according to what Yun Yi said in his letter, when the population of Yunhua County reaches a certain number, the Yun clan does not need to worry about anything, even if the innate martial artist is coming, he is not afraid, if there is a war, the Yun clan has enough population to protect itself.

Yun Yuankai also had another thought in his heart: if Yun Yi didn't have such a high martial arts talent, maybe the Yun clan would develop more rapidly under the leadership of Yun Yi, Yun Yi was an excellent patriarch, and he Yun Yuankai could only be regarded as a qualified manager.

Yun Yuankai sobered up from deep thought, sorted out the thoughts in his mind, and then Yun Yuankai sent someone to invite the clan elders to discuss Yun Yi's proposal together.
