In order to use the accumulated number of draws to turn over all the cards at one time when the flop is carried out in the system at a critical moment, Zhu Youzhen has saved a lot of lottery times.

But now... Gone!

Nothing! Although it is not yet known how many points are required for these books, the more than 100 entries for the draw turned into 18 points.

Zhu Youzhen felt that he was at a loss...

【Ding! System prompt: Hosts should not look at the exchange price of books in the mall before coming...]

The voice came out, and Zhu Youzhen was stunned.

Then I casually clicked on a book of "Glass Industrial Manufacturing", only to see that the end was clearly written "Redeem the required points: 1 point"...

Hiss... Zhu Youzhen gasped.

Compared to the more than 100 books that I don't know what they are, this self-selective way of redeeming is undoubtedly more helpful for building a more systematic scientific system.

The so-called lack of where to exchange, when will there be no time when the exchanged books will not be used, so after thinking for a while, Zhu Youzhen made a judgment.

That is, this updated system is indeed much better than the previous lottery system that will become very weak from time to time...

But on a second thought.

Zhu Youjian opened the search box in the system exchange mall and silently typed....

Nuclear-powered aircraft carrier manufacturing technology...

Rise!

The exchange mall instantly displayed hundreds of books in different fields, and there was a next page??

Zhu Youzhen was stunned for a moment, and said, "What's going on?" ”

Unexpectedly, the system responded coldly: "What the host is searching for can be called the crystallization of human technology at a stage, and it needs the blessing of thousands of different kinds of technology... So the search results will show up all the relevant technologies..."

Yes, it seems that the dream of an aircraft carrier has been shattered, and these thousands of books hammer him to death Zhu Youzhen can't afford it at present.

I can only look at it and think about it..

I casually exchanged the copy of "Industrial Manufacturing of Glass", and also exchanged the chemistry books mentioned earlier. The book "Steam Locomotive Manufacturing Technology" Zhu Youzhen also did not let go.

But before that, Zhu Youzhen felt that he should still take it step by step, for example, starting with the glass industry first, so he gathered a lot of people, including Wang Yisi, who has become famous in the capital in recent days because of the loom.

The simple thing is that it is extremely simple to obtain raw materials, and the difficult thing is that it requires a large number of production equipment as a blessing.

Otherwise, the kind of transparent crystal-like glass in later generations, in the current Ming Dynasty can only think about it, now the most is glaze, and there are glaze factories in the capital.

But this kind of glass is far worse than glass...

As one of the commonly used livelihood products, the detailed theory and steps of manufacturing glass are detailed in the book that Zhu Youzhen just redeemed.

Although Zhu Youzhen does not have much industrial foundation, he has read all kinds of industrial books for such a long time.

Under the influence of the ears and eyes.

In a few moments he understood the parts necessary for the production of glass.

The first step in the production of glass is to consider the construction of a crucible furnace, which can withstand more than 1,500 degrees of high temperatures.

After all, only at such high temperatures can raw materials such as limestone, quartz, and soda ash used to make glass be heated and melted, and the manufacture of such crucibles is not a simple matter.

It's just that Zhu Youzhen, as the emperor, naturally can't do everything himself.

It is wisest to leave it to someone with professional knowledge.

Not for a while.

Many researchers from the Daming Academy of Sciences and a large number of ministers from the General Administration of Industry, the General Administration of Ordnance and even the Ministry of Industry appeared in the palace, of course. It's certainly not the East Warm Pavilion.

Zhu Youzhen's small place could not accommodate so many court officials.

It's almost time for people to come.

Zhu Youzhen was the first to speak: "I called you here today because I have something to look for you, but before talking about today's matter, I want to test the ministers first... Who knows how glass should be made? ”

As soon as the question was raised, a minister of the Ministry of Industry saluted and replied: "Your Majesty. Although the production method of this glass is quite complicated, it is still roughly divided into several parts. ”

"First of all, the raw materials are heated by a special furnace, and then the impurities are removed with a special primer, and then they can be put into the abrasive tool to cool and form."

The official's words roughly describe the production method of the existing Ming glaze, but some people also call the glaze glass.

Therefore, the minister of the Ministry of Industry also thought that Zhu Youzhen was talking about glass.

Unexpectedly, Zhu Youzhen shook his head and said, "What is the Ming Dynasty going to develop now?" I'm telling you, it's industry! ”

"Since we want to develop industry, we must look at the production of everything from an industrial perspective! That's why I'm gathering you today to tell you that I want to build a new industrialized glass factory. ”

After Zhu Youzhen's words blurted out, many officials did not speak despite their doubts, and Xue Fengxiang, the secretary of the Ministry of Industry who came to meet Zhu Youzhen, had to speak: "Your Majesty."

"Doesn't Jingshi already have a glass factory now?.. And this glass is only for decoration... It's really useless. ”

What Xue Fengxiang said can be said to be true, in the Ming Dynasty, the usefulness of glass was still very limited.

Of course, this reason is also inseparable from its high production cost and its crisp and fragile despite its diverse colors and shapes.

So, even if someone wants to buy such a product.

After buying it home, it was just an ornament added to the home.

Zhu Youzhen waved his hand and said, "I know what you want to say, but I tell you today that from now on, glass is glass, and glass is glass, and there is an essential difference between the two. ”

Many officials were stunned immediately, and secretly said in their hearts: "Is there any difference between this?" ”

"I have a book on the Industrial Manufacturing of Glass, and the content is about how this glass is produced by industrial means."

"I summoned you here today to do a division of labor."

"The Royal Academy of Sciences sent people to understand the technology, and the General Directorate of Ordnance was responsible for the production of the required equipment and the deployment of enough steam engines to cooperate with the production."

"The General Directorate of Industry is responsible for the construction of the site.."

Speaking of this, Zhu Youzhen paused, looked at Wang Yisi on the side, and continued: "I'm afraid that Wang Aiqing has been the most experienced recently... The construction of your weaving mill is almost over, and you will borrow a few days to build a glass factory! ”
