The Forbidden City of the North of the Ming Dynasty.

In the workshop of the imperial supervisor, the Emperor of the Apocalypse, Zhu Youjiao, inspected the work inside with Wei Zhongxian, the eunuch of the celebrant Bingbi and the commander of the East Detective Factory, and a young Taoist.

At the beginning of the founding of the Ming Dynasty, the Ming Dynasty set up 12 eunuchs, 4 divisions, and 8 bureaus to serve the emperor and his family. Later, it was commonly known as the "Twenty-four Yamen of the Inner Court".

Of course, the 24 Yamen is not completely the institution of the eunuch system in the Ming Dynasty, only because of its special palm seal eunuch withdrawal, so it is often misunderstood by modern people, and even the Later Jin Ye History shows that there were 100,000 eunuchs in the Dynasty, and the Later Jin is less than 11, so as to prove that the Ming Dynasty is not as good as Jin.

In fact, the vast majority of these so-called 100,000 eunuch units were craftsmen who moved from Nanjing in the 24 yamen, and at that time, there were only 27,000 craftsmen in the capital including other ministries and guilds.

In particular, there are no hard rules for the chief eunuchs in the 24 yamen, and they must use eunuchs, but because of the relationship of royal trust, they send eunuchs to take charge of their duties.

For example, now Gao Jingfei and his royal supervisor are responsible for "all the wooden utensils used in the front of the imperial court, such as the screen, the bed, and the red sandalwood, ivory, ebony, and luodian toys, all of which are made." There is also a member of the supervisor of the Renzhi Palace, who is in charge of the books and picture albums written by the book in the Wuying Palace, etc., and plays them in front of the palace. ”

In fact, in addition to the eunuch who is a domestic servant, the two members of the imperial prison and the outer prison are ordinary people, as well as the bookkeepers, the masters, the writers, and the supervisors.

At this time, the eunuch with the palm print of the imperial eunuch was nodding and bowing beside the emperor and the nine thousand years old, watching the supervisor and several craftsmen in the workshop operate in front of several kilns according to the instructions of the young Taoist.

And the other subordinates have no qualifications to approach the imperial front at all, and it is also for secrecy and avoiding suspicion.

After a short time, I saw a stout craftsman scooping out a ball of red-hot glass liquid with a wooden rod and iron spoon, and then slowly pouring it on top of the smooth red-hot copper plate that had been prepared, and fixing it with a copper frame around it.

If you want to further cut and process into a finished product, you also need to go through steps such as annealing and grinding.

When the cooling was over, the craftsmen took cotton gloves and picked up the glass plate that was still hot to show the emperor and others, and saw a glass plate that was two feet square and relatively transparent, but the whole body was glowing with light blue, appeared in front of everyone.

The others were amazed when they saw it, because these craftsmen were familiar with the process of firing glass, after all, the glass has a history of more than a thousand or two thousand years in Middle-earth. But such a large piece of flat glaze, the texture is still so transparent, it is unheard of for these ancient people, let alone seen.

Gao Jingfei was not very satisfied, but commented lightly:

"It's okay, but this piece can't be used as a mirror, so it can only be smashed."

The color is slightly blue, according to the chemical knowledge in his memory, Gao Jingfei thinks that it should be the relationship between the glass that may contain metal oxides, so it is blue.

Although this pale blue is more beautiful, it is not suitable for mirrors.

However, Zhu Youxiao said with some pity when he heard this:

"Such a good glass, it's good not to make a mirror and make a screen, it's a pity to smash it."

Immediately, he left this piece of glass for the craftsmen of the imperial prison to polish and smooth, and then prepared to make the wooden frame himself, which could be placed in the study to enjoy when the time came.

In the emperor's opinion, such a large piece of colored glass, with color, must be very expensive among the people.

Then another craftsman scooped out a spoonful of molten glass from another stove and spread it on a copper plate to cool it, only this time it was red.

This time Gao Jingfei didn't speak, and the emperor spoke first:

"Go and polish this piece well, and I will give it to the queen myself when the time comes!"

Then a third craftsman scooped out the molten glass from the furnace again, and this time the formed glass plate was green and a little more cloudy than the first two.

Gao Jingfei shook his head, understanding that this was the relationship between raw materials or other impurities, and some metal components would make the glass colored, which was inevitable in ancient times when there were no modern industrial treatment methods.

But what he wants now is colorless transparent glass, so he waved his hand and released a golden flame, in the exclamation of the craftsmen, the pale green glass was wrapped and smelted, and after a while, some impurities turned into green smoke and drifted away, and when Gao Jingfei retracted the Shenxiao Golden Fire, the glass plate had become the purest white crystal-like colorless and transparent, and it was transparent and eye-catching under the firelight.

Of course, several people around them don't like this colorless glass as much as they like the previous pale blue and light red.

Because Middle-earth's appreciation of gemstones and the like is led by color, but those with strong green and bright red are the best. In the Middle Earth region, in addition to the warm mutton fat white jade, all jade gems are jade-colored, followed by crimson, blue, yellow, blue, white and ink, but colorless, transparent or light-colored are regarded as inferior.

Even the same is true in modern times, Gao Jingfei harvested the jadeite dragon vein in Shan earlier, once checked the situation of the modern jadeite jade industry, in fact, before the nineties of the last century, colorless and transparent jadeite is only a worthless category, until the new century, some light-colored, colorless jadeite has gradually risen sharply because of the pursuit of young people, but there is still no strong color of the same water jadeite price is high.

Gao Jingfei, who completed these, said to Zhu Youxiao:

"According to this example, a few more tests can be used to obtain transparent glass, supplemented by silver plates, and then finely polished, you can make a clear mirror that can be seen by people."

"This glass silver mirror is not easy to manufacture, and it is easy to be damaged, such a large piece is an extremely rare thing, and the price of selling a copper mirror should be very suitable, right?

"It's a good fit, it's a good fit!"

Lao Wei almost smiled from ear to ear, this glass plate removes labor, the cost is only a few dozen copper coins, even if you add labor and silver, the outer frame, it is only a few taels of silver, but it can be sold for a high price of more than 1,000 taels, this is simply a million profits!

And Lao Wei felt that those colored glazed creations could be sold for a higher price than the glazed silver mirror if they were polished well.

Gao Jingfei instructed Lao Wei according to the methods of those merchants he knew in modern times:

"The number of early shipments of this mirror must be small, and the patterns are not too much, one or two new patterns are produced every year, so that the novelty can last for a longer time, and it is necessary to create a picture of a price without a market, and then slowly ship, because others cannot imitate, so the pricing power is in our hands, this is the monopoly!"

"So Duke Wei should pay attention to secrecy, give those craftsmen enough oil, water and silver, but restrict them from going out, once one runs out, or leaks the secret recipe, this trick will not work!"

"After all, wealth moves people's hearts, and those who are greedy for money may not be able to do anything!"

Wei Zhongxian smiled fiercely when he heard this:

"Let's see which of his ideas dares to hit the glass mirror?!"

Cutting off people's wealth is like killing their parents, especially this royal transaction is related to the emperor's money bag, Wei Zhongxian attaches more importance to it than his own small treasury.

If you really want to have that blind person, he doesn't mind letting the other party feel the means of Dongchang and Jinyiwei's edict.

"Brother Shen!"

"Hmm!"

Shen Changqing walked on the road, and when he met someone he knew well, he would say hello to each other or nod his head.

But it doesn't matter who it is.

There was no superfluous expression on everyone's face, as if they were very indifferent to everything.

on this.

Shen Changqing is used to it.

Because this is the Demon Suppression Division, it is an institution that maintains the stability of Great Qin, and its main responsibility is to kill demons and monsters, and of course there are some other side jobs.

Arguably.

In the Demon Suppression Division, everyone has a lot of blood on their hands.

When a person is accustomed to seeing life and death, then he will become indifferent to many things.

When he first came to this world, Shen Changqing was a little uncomfortable, but over time he got used to it.

The Demon Suppression Division is huge.

The people who can stay in the Demon Suppression Division are all powerful masters, or people who have the potential to become masters.

Shen Changqing belongs to the latter.

Among them, the Demon Suppression Division is divided into two professions, one is the town guard and the other is the demon exterminator.

Anyone who enters the Demon Suppression Division starts with the lowest level of demon slayer.

Then step by step, he is expected to become a town guard.

Shen Changqing's predecessor was a trainee demon slayer in the Demon Suppression Division, and he was also the lowest level of the demon slayer envoys.

Have memories of the predecessor.

He is also very familiar with the environment of the Demon Suppression Division.

It didn't take long for Shen Changqing to stop in front of an attic.

Unlike other places full of slaughter, the attic here seems to stand out from the crowd, and in the bloody Demon Suppression Division, it presents a different tranquility.

At this time, the attic door is open, and there are occasional people entering and exiting.

Shen Changqing only hesitated for a moment, and then stepped in.

Access to the attic.

The environment has changed in vain.

A burst of ink fragrance mixed with the faint smell of blood came to his face, making his brow furrow instinctively, but quickly stretched.

The smell of blood on everyone's body in the Demon Suppression Division is almost impossible to clean.
