The spring flowers are blooming, and the weather in late February has gradually warmed up, and more than 2,200 soldiers of the Shenji Battalion lined up in a neat procession and arrived at the fire kiln at the foot of Da Hyeon Mountain in the south of the city in half an hour.

It's not far from the limestone mines, and as soon as you arrive, you can't open your eyes because of the dust in the sky.

However, except for a few complaints, no one commented.

Because they have been shaken by the mountains of limestone powder, and what can they say when they see the people going back and forth in the ash heaps like ants?

Everyone closed their mouths, held their breath, and moved on.

Turning a col, the environment is much better, but many of the leaves have a thick layer of ash on them.

In the col, there are five caves side by side, which are built with the help of the earth slope under the hillside.

At first glance, it seems to be the same, but on closer inspection, each cave is slightly different.

Seeing that the prince's honor guard was also there, everyone became curious. "Yesterday's announcement caused such a big turmoil, and the second brother was not in charge of the overall situation in the government, so he came over?"

The Jinyi guard in charge of military discipline shouted: "Han Chongxun, speak a warning." ”

Everyone laughed, but everyone's mouths were tightly closed, for fear of being warned, or even punished.

The people came to a flat place at the foot of the hillside, and more than 2,000 people marched in formation, and soon formed a neat phalanx.

Above the cave not far from them, Zhao Dezhao stood at the window and looked at the people lined up below, and behind him, Pei Ge'an was studying the functions of different caves.

This technical direction is her weakest, and she has very little contact with the technology of materials science and technology in modern times.

The only thing I am familiar with is because of the construction of several pharmaceutical factories and chemical plants.

"Husband, you haven't been exposed to glass firing in modern times, have you? Why do you know how to decolor glass, and also know how to make quartz optical glass? ”

Zhao Dezhao glanced back at her and said with a smile: "I know more?" You don't know everything. Like those political systems, I'm studying in modern society, and you're not interested in those at all. ”

Pei Ge'an pursed his lips, stood up, walked to his side, and looked at the Jinyi guard at the foot of the mountain.

"You've pushed so many things today, just for them?"

Zhao Dezhao smiled: "You have made another mistake, in this era, what is the most important?" Talent? What resources are most important? Or people! All wars, the development of society, are driven by people.

Their identities are different, and they can radiate the military general class of the entire Great Song Dynasty, and they are the most important to us now. ”

"Through them, you can control most of the soldiers and horses of the Song Dynasty?"

"It's pretty much the same, it's not a big problem for other projects to be one day earlier or one day late, but they must not be distracted. You continue to study, and I'll go down and arrange it first. ”

Zhao Dezhao walked out of the room, Liu Xiao hurriedly greeted him, and just as he was about to speak, he heard Pei Ge'an ask behind him: "Are you hiding something from me?" ”

Pei Ge'an is not stupid, although the modern Zhao Dezhao relies on the first opportunity, is bold and reckless, and has become a hero, it can be said that he knows nothing about technical things.

Not to mention glass firing, do ordinary people know how to design a glass kiln?

Zhao Dezhao, a scumbag, understands this, which is not in line with common sense at all.

Zhao Dezhao looked back and smiled. "There's something, but it doesn't matter."

Zhao Dezhao strode down the hillside, and Liu Xiao followed behind and said with a smile: "Second brother, now the masters of the five kilns are waiting for you, why do you want these brothers to help?" I'm afraid they don't want to do it......"

"I have a way to get them to do things with their hearts. …… Have the families of these masters been arranged? ”

"It's arranged, and those gunpowder masters, all arranged in a Zhuangzi, not far from the south gate of the city."

Zhao Dezhao is very important to the confidentiality of technology, especially when it comes to important technologies.

The technology of the glass kiln was kept secret as well as gunpowder, and later explosives, and the manufacture of muskets.

With glass, sextants, telescopes, microscopes, these instruments were possible.

Allowing such a technology to appear nearly a thousand years in advance, if it is not kept secret, and it is spread out, it is tantamount to causing trouble for yourself.

Coming to the front of the team, no one dared to speak because of the staring Yuan, but when they saw Zhao Dezhao, everyone's face showed a smile.

In addition to the identity of superiors and subordinates, he and many people can be regarded as brothers.

Zhao Dezhao stood still, his five fingers straight, and raised his elbow to the tip of his eyebrows. "Brothers, it's hard to run all the way from Kaifeng Mansion."

All right fists in the chest. "It's not hard."

"I know that your brothers are suffering, so in addition to half-day training in the past few days, I just let you take care of yourself. I asked you to help me today because there is nothing in this col that has never been done before.

In this world, I trust you the most, and I can only let you do some work. Everything about this col is a top secret and must not be revealed.

These days, you have been helping here, and you have to forget what you see when you go out.

After these few busy days, you have made something that is qualified, and I will give each of you a set in the future. ”

Pan Weide, who was standing at the front, took a step forward and saluted: "Report." ”

"Speak."

"Second brother, can you introduce what it is? What do we need to pay attention to? ”

Zhao Dezhao said with a smile: "We want to create the legendary clairvoyant mirror, and in the future, each general can be equipped with one." And if it is made, the first thing to equip is our brocade guard. ”

There was an uproar in the audience, clairvoyant, isn't this something in a mythological story?

However, for fear of being punished, although the shock was not small, no one dared to interject.

"Therefore, you must work hard, and you can't be disrespectful to the master because of your status, and obey the arrangement. At the end of these days, the most active personnel will be selected and prioritized. ”

Use binoculars to attract them, and you are not afraid that they will be undisciplined and lawless.

In fact, they can't master the technology, because the main accessory of the telescope is the lens, and the material of the lens has more to do with the material than the technology.

Even if they work here for a few years and don't know the formula, they can't make good lenses.

Zhao Dezhao asked them to help, not to really let them work, but to get something they were interested in to attract them.

He is not afraid that they will cause trouble in the city, but he is afraid that he will not have the energy to take care of them during this time, so that they will have no restraint and their hearts will be scattered.

The clairvoyant mirror in the myth, not to mention that it can make them settle down for four or five days, even a month, they can endure it.

And if you want to build a qualified telescope, Zhao Dezhao is very familiar.

During the Ming Dynasty, the crystal of the Ma Zhide family was used as a foundation to develop the high-end lens industry.

But that was the Ming Dynasty, four hundred years have passed, and the social development is much more advanced than it is now.

At the end of the Five Dynasties and Ten Kingdoms, the social gap between the Ming Dynasty and the Ming Dynasty is really a few hundred years......

Now there is no Ma family, but he has mastered a full set of techniques, and now it is nothing more than a copy in the Song Dynasty.

The Song Dynasty did not have a crystal industry, but the firing of glaze also has a history of thousands of years.

In the Bronze Age, when copper was smelted, people had already discovered that glass appeared when the associated stones of copper ore were fired.

Since then, glaze, as a five-color stone, has always been the most precious "treasure".

But people don't decolor by neutralizing minerals, so glass has been developed in China for thousands of years, but glass was not made until the 19th century.

Westerners fired glass in the fifteenth century and have always believed that glass is green and cannot be changed.

It was later discovered that the green color came from a small amount of iron in the raw material, and the compound of ferric iron gave the glass its green color.

With the addition of manganese dioxide, the original bivalent iron becomes trivalent iron yellow, while tetravalent manganese is reduced to trivalent manganese and is purple.

Optically, yellow and purple can complement each other to a certain extent, mixing together to become white light, and the glass will not be colored.

Nowadays, not only a large amount of limestone, quartz sand, moonstone (borax), and manganese ore have been collected in the col, but it is only a matter of time before a qualified glass is prepared.

It is worth mentioning that manganese ore, this kind of soft manganese ore is often popular because it will imprint the pattern of leaf veins on the associated stone, but no one wants the real soft manganese ore.

Zhao Dezhao didn't know it at all, but when he heard the story in the Ming Dynasty, he learned that soft manganese ore was actually manganese dioxide needed to fire glass.

In fact, this ore is very common, thousands of times more than borax, which is scarce.

In this era, no one can help him remove all obstacles and provide all the conditions like Zhu Di, so he can only come by himself.

Therefore, he did not have time to focus on these aspects during this time, and only when his official duties were regularized did he have time to make technical improvements.

However, now he has Pei Ge'an to help him, and she is watching, which is better than what he is doing.

However, she has no experience in industrial layout in ancient times, and she still has to do many things by herself.

It's like building bearings, without this kind of product, many plans can't be implemented, and Pei Ge'an doesn't understand these at all.

On the way back, he met Tong Liang, who came to find him. The Firearms Battalion and the Surveying and Mapping Battalion were also the same as the Shenji Battalion, and he was assigned to the Iron Battalion and the Wood Battalion to help.

I don't expect them to do much, but I don't let them be idle, and I can't let them play wild.

"Second brother, the people from the firearms battalion and the surveying and mapping battalion have already been arranged, and when I came, I saw Cai Tingshi preparing the honor guard, and Fu Yaozi and Shen Zhuan made them seem to be about to arrive."

It's been four or five days, no matter how slow it is, Shen Yilun and they should have arrived.

"Send someone over and wait at the North Gate Wharf, and notify me when the ship comes, and I will also go to the North Gate to meet me."

Shen Yilun, as a subordinate, doesn't have to greet him, but Chen Tuan was fooled by him, and he still has to count on him to help him publicize, so he can't be too lazy.
