Regarding the Qingheyu training camp, a person familiar with the matter said:

"Don't mention the government soldiers, the ordinary captain of the border army may not be able to beat a soldier in the Qingheyu training camp one-on-one. In that year, 800 Ding slaughtered 20,000 elite Turks, and even those 800 Ding were sent back for training, these soldiers were the elite of the elite in the hands of the saint, known as half an army to destroy 100,000. ”

Half an army is 10,000 people, and 10,000 people can destroy 100,000 enemy troops.

This kind of combat effectiveness is understood by anyone, and this is a sharp weapon in the hands of Emperor Li Shimin of the Tang Dynasty.

How many people are in the Shen Ce Guard, this data is not even known to the Ministry of War, let alone ordinary officials.

On both sides, Cui Junsu did not leave the imperial city at all, and went straight to the general accounting room of the general office of the general office after leaving the Taiji Palace, and only said five words to Liu Ruyu.

In five sentences, it is clear that next year's silver mine will be the silver household department, the general shipping department, and the four northern counties.

After clarifying the situation, Cui Junsu personally escorted the silver balls left by the former Sui in the warehouse.

These silver balls are the Zhenguo silver of the former Sui Dynasty, and it is said that there are hundreds of them, but in fact, some of them have been secretly replaced, with a layer of silver on the outside and lead on the inside.

Before cutting it, the people of the big library couldn't tell which one was real and which one was fake.

Therefore, Cui Junsu wanted to personally escort him to the four northern counties, and then talk to Liu Mu about the most direct conversion method, which was to fold it in half, and then a silver ball to fold it for 1,400 yuan.

As for the ordnance expenses of the poor Yanagi Hanahara Workshop, let Yanagi deduct it from the income of Iwami Ginzan until it is sufficient.

However, it is also necessary to first prepare the household department with a value of not less than 1 million yuan of town bank within a year.

Three days later, Cui Junsu came to Huayuan County.

The mint of Yanagi is located in Hwawon.

Cui Junsu, as the head of the household, came to Huayuan but was told that Liu Mu was in the forbidden area at this time, where no one could approach at any time unless the saint was in person, the soldiers were in the city, and the world was turned upside down.

At the moment, I can only send a letter in, and when Liu Mu can see it, it is unknown.

Cui Junsu was not in a hurry, and motioned to the officials who received him to arrange a place for him to rest, and then arranged for someone to hand over the silver ball he brought, and then arranged for someone to make a detailed list of the accounts of this armament, which was also the final statement.

After coming to the resting place, Cui Junsu said to his master: "You must remember that no one should walk around at any time and on non-official business, this Huayuan is not an ordinary place. If you break into a place you shouldn't go, you'll stay here forever, or you'll never see the light of day in the mines. ”

"Yes!" The crowd responded in unison.

Huayuan County's ban was notified to the court by Emperor Taishang Li Yuan when he was emperor.

After the Tang Emperor Li Shimin ascended the throne, he made this ban stricter, and divided Huayuan into three circles, and the second circle was already considered a forbidden area.

In fact, there is a fourth circle among them, a fourth circle that even the Tang Emperor Li Shimin does not know.

The most important thing in that circle at the moment is Liu Mu's artifact: the steam engine research and development center.

Liu Mu's attitude is that countless coins smashed into it will also be completed by the steam engine.

The second key research, which has not yet officially begun, is electricity, which is called lightning control in the research center, and is still in the shallow trial stage of various craftsmen.

Yanagi's knowledge of electricity is limited to high school, but things like telegraphs are something that Yanagi studied when he was a soldier.

It was only after the official use of radio that the electron tube was invented.

The first radios were made by coils of carbon rods, copper wires, magnets, and other items. The wired telegraph is simpler, and if there is a dry battery, a foot-long copper wire can make the simplest wired telegraph.

The reason why Yanagi asked someone to study this, but did not step up the study, was that Yanagiki's telegram was for the railway.

Cui Junsu waited in Huayuan for another three days before Liu Mu came out of the forbidden area.

A new reciprocating miniature steam engine has been completed, the initial operation feels OK, this thing will continue to run for more than ten days, and then consider improvement and perfection after testing, this year Liu Mu did not think that there would be a real industrial-grade steam engine was built, this thing is difficult for Datang in this era.

The difficulty lies in the quality of the steel, the difficulty in the sealing, the difficulty in the relatively precise structure, and the difficulty in the continuous testing and thoroughness of each part.

Everything depends on constant experimentation, experimentation, and experimentation.

Cui Junsu didn't show any dissatisfaction when he saw Liu Mu, but said very politely: "Liu Juma's expression is tired for many days. ”

"Well, the craftsmen work harder than me." Yanagi smiled and clenched his fists.

Cui Junsu didn't think to ask Liu Mu what he was doing, even the Tang Emperor didn't come to inquire about everything here, he didn't want to break the taboo.

However, Huayuan's production is in the eye.

Not to mention the new type of plow, the plough and hoe shocked many craftsmen in the Ministry of Industry, not the iron of the hoe, but the hoe of willow wood does not need to be grinded, in the daily labor, the hoe is used more and more sharp, which makes the craftsmen of the Ministry of Industry convinced.

The principle is simple, that is, the iron quality on the front and back of the hoe is different, so the ground is used instead of a grinding stone when in use.

It sounds simple, but in reality no one has ever thought of it, and no one dares to think of it like this.

This is just farm tools, how terrible Liumu's ordnance is, only those who have seen the terrifying power of the little general's cannon can understand why Huayuan County is a forbidden area.

Cui Junsu said straight to the point: "Liu Juma, you must already know about the silver ball, my opinion is that no matter whether it is true or not, it will be converted by half, and whoever takes advantage of it and who suffers does not have to care." ”

"Well, it's a trifle. The meat is rotten in the pot, and it is Datang inside and out. Liu Mu agreed without saying a word.

Cui Junsu said again: "Before I came, I said a few words to Second Sister Ling, these silver balls are not enough to pay for the new armament of Gaochang, and the household department also wants to add one million yuan worth of silver bricks to the town treasury next year. There is also the change of clothes of the border army, which costs money. The bad part, Iwami Yama, you take it first. ”

"Okay, no problem. As long as you let me dig, I'll let go of digging. But there is a sentence ahead, Hubu doesn't dare to think that I am a cornucopia here, let alone a silver mine, even a mountain of gold, which must be dug out with a hoe and then loaded and shipped back. That's not too much. ”

Cui Junsu laughed after hearing this: "Two million small silver coins a year, I'm afraid it's no problem." ”

Yanagi nodded.

Cui Junsu said again: "The general division, the four northern counties, and Iwami Mountain. Can you give the household 4 million yuan worth of coins and materials a year? ”
