Benefiting all people? Emperor Yong'an couldn't see any joy or anger on his face, "So, what exactly do you think?" How do you think it should benefit all people? ”

Gu Yuanji quickly said: "The minister just thinks that this glass mirror can be seen very clearly, and it is more convenient than the bronze mirror." I heard that the treasure mirror building has only been open for less than half a day, and it has been sold out.

As you can imagine, many people want this glass mirror. If it can be sold all over the country, it will not only benefit all the people in the world, but also make a lot of money and increase the tax revenue of the national treasury. ”

Emperor Yong'an's face was a little cold, and he deliberately asked: "What you said has some truth, but as far as I know, the glass mirror here is not suitable for long-distance transportation, otherwise it will be easily damaged." How's that to be? ”

"The minister has also heard about this, so the minister thinks that he should choose suitable places across the country to build glazed kilns and burn more mirrors."

Emperor Yong'an suddenly asked, "But in this way, wouldn't it be necessary to announce the recipe for firing glass and making mirrors?" ”

Gu Yuanji said as a matter of course: "As long as you apply for a patent in the Patent Division, there will be people from all over the country who will burn the glaze, and they will naturally have to pay patent royalties if they use the formula." ”

"But then the recipe can't be hidden." Emperor Yong'an's face turned completely cold, "So you came here to ask to see me, just so that I could announce the glass recipe for fear?" ”

When Gu Yuanji heard this, he immediately realized that the situation was not good.

He can become a big official like the head of the household department, of course, he is not a fool.

As soon as he heard Emperor Yong'an's tone, he knew that something was wrong.

Emperor Yong'an is angry!

But why?

Could it be because Liulifang and Baojinglou are the private property of the Qin Palace, and His Majesty is unwilling to cheapen those merchants?

However, this mirror is not convenient for long-distance transportation, and it is best to build a glass workshop to make mirrors in various places.

According to the information he inquired, there are two kinds of mirrors in the Treasure Mirror Building, one is a mercury mirror and the other is a silver mirror.

The effect of mercury mirror is not as good as that of silver mirror, but the price is much lower than that of silver mirror.

If you use a relatively cheap wooden frame, the price can be cheaper than a copper mirror, and even ordinary people can buy a mercury mirror.

Such a good thing, if it can be promoted to the whole world, will definitely make many people afford to use the mirror.

Isn't it a good thing for all the people of the world?

Why is Your Majesty so angry!

Gu Yuanji was aggrieved in his heart, he mentioned this matter to Emperor Yong'an, although he was a little selfish, but he really thought about the people of the world.

Your Majesty has really wronged him!

Gu Yuanji's mind was racing, pondering what Emperor Yong'an said, and suddenly realized something.

Could it be that this glass recipe can't be leaked out?

He thought for a moment and said cautiously: "Your Majesty, the minister just thinks that this mirror can benefit all people. The minister would never dare to let His Majesty make this glass recipe public. ”

Although he didn't know what was wrong with this glass, he had already realized that Emperor Yong'an cared about this recipe very much, so it was right.

Emperor Yong'an really snorted coldly: "Hmph, forgive you for not having the guts!" ”

It sounds infuriating, but it's not as scary as it was just now.

Gu Yuanji secretly breathed a sigh of relief.

Emperor Yong'an took out something and said to Gonggong Li: "You take it and show it to him." ”

Gonggong Li immediately took it respectfully, and came to Gu Yuanji with small steps: "Gu Shangshu, please take a look." ”

At this time, Emperor Yong'an said: "Gu Yuanji, look at what this is. ”

Gu Yuanji didn't need to look closely at all, he recognized at a glance that Gonggong Li brought a magnifying glass.

He couldn't figure out the intention of Emperor Yong'an to ask, so he could only honestly take the magnifying glass and look at it carefully, and after confirming that it was really a magnifying glass, Gu Yuanji immediately said: "Your Majesty, the minister recognizes this thing, this is a magnifying glass." ”

"If only you knew it!" Emperor Yong'an snorted coldly again, "Then do you know what this magnifying glass is made of?" ”

Gu Yuanji was stunned for a moment, and subconsciously said: "As far as the minister knows, the lens of this magnifying glass is carved and polished from water jade. ”

Of course he knows that!

It's really strange, why does Your Majesty ask that?

Who knew that Emperor Yong'an said: "You take a closer look." ”

Gu Yuanji was puzzled, but he still picked up the magnifying glass and observed it more carefully.

Isn't this translucent lens water jade?

Seeing that he didn't recognize him, Emperor Yong'an couldn't help but coldly hook the corners of his lips, and looked at him with some disgust: "This thing is colorless and transparent glass, I call it glass." ”

Gu Yuanji was dumbfounded for a moment: "Liu...... Glass??? ”

This thing is actually made of glass?

Yes, why didn't he think of it!

Wasn't the mirror he just bought made of silver and glass?

It is said that at the palace banquet that day, the mirror that Princess Qin presented to the queen was made of water jade.

Now, you can use glass to make a mirror.

Since glass can be made into a mirror instead of water jade, what is so difficult about making a magnifying glass instead of water jade?

By the way, the clairvoyance presented by the Marquis of Wuyang used water jade to make lenses.

Could it be that this glass can also be made into clairvoyance?

As soon as Gu Yuanji thought of this, he heard Emperor Yong'an say: "The War Bureau has successfully created clairvoyance out of glass. Gu Yuanji, do you still want me to disclose this glass recipe now? ”

Gu Yuanji was so frightened that he quickly knelt on the ground: "The minister will never dare!" ”

Obediently, this glass can still be made into clairvoyance!

He knew that to make clairvoyant water jade, it must be colorless and transparent, pure and free of the slightest impurities, and it should be big enough.

This kind of water jade is not easy to find.

Naturally, it is also highly valuable.

But this glass is made of sand!

Isn't it possible to burn as much as you want?

The glass is colorless and transparent glass, if the glass square is announced, there are people with bad intentions to burn out the lens and make clairvoyance, wouldn't it be infinitely harmful?

It would be even worse if this spread to the aliens and Gentiles!

Thinking of this, Gu Yuanji instantly realized the importance of the glazed square.

He hurriedly said: "Your Majesty, the minister thinks that the glaze formula is very important, and it must be cautious and must not be leaked out!" ”

"Hmph, do you still need to talk about this kind of thing?" Emperor Yong'an glared at him with disgust, "For the sake of your loyalty and errands, I don't think I have heard what you said before." No next time, though! ”

Gu Yuanji hurriedly thanked him: "Thank you for your kindness, and I am willing to die for Your Majesty!" ”

Emperor Yong'an was quite satisfied with his ability, and although he was dissatisfied, he still let him go.

Gu Yuanji saw that he had escaped, and he couldn't help but secretly breathe a sigh of relief.
