Sister Qin thought about it. Although Shen Nianzhi was interested in various courses before, he did not show any particular fascination with any of them.

What made her so troubled now was probably the two Britons that the princess had just recruited from a small coastal country a few days ago.

The two men were glassmakers who had escaped from an island.

They took various fishing boats all the way to a small coastal country, hoping to find a ship back to Great Britain to take them on.

After Qingtian learned that they were glassmakers, he let them on board, and the fare only needed to be exchanged for the glassmaking skills they knew.

So the two of them got on the boat happily. Qingtian also ordered people to find the materials they needed and asked them to demonstrate how to make glass in front of all the students.

At that time, the two people made a very beautiful glass cup, which won everyone's admiration.

"Are you interested in glass?" Sister Qin asked tentatively.

Shen Nianzhi was shocked when he heard this: “Sister Qin, how did you know.”

"I can't guess what you're thinking," Sister Qin said, sitting across from her and asking, "What's wrong with wanting to learn how to make glass? Is it worth it for you to go through so much trouble?"

Shen Nianzhi said with a bitter face: "But what you all want to learn are steam engines and gunpowder. Some people want to learn how to draw maps and how to guide ships on the vast ocean. I am the only one who likes beautiful things like glass.

"Even if you learn it, what's the point? Is it just to sell it for money?

"It seems that I can't do anything practical for Da Qi or the people.

"This makes me feel like I have no conscience and I'm sorry for the princess's training and dedication to me over the years."

Shen Nianzhi was still young when she first came to the girls' school. Over the years, she has sincerely regarded the girls' school as her own home, and has an almost blind admiration for Qingtian.

So when she discovered that the princess provided so many things for everyone to learn, but she was so superficial and was only interested in beautiful glass, she couldn't help but fall into deep self-doubt and disgust.

Unexpectedly, after hearing her troubles, Sister Qin not only did not sympathize with her, but also burst out laughing.

“Sister Qin, why are you laughing at me when you don’t help me!” Shen Nianzhi pouted and complained while shaking Sister Qin’s arm.

"You silly child, it's just a small thing, why are you agonizing over it for so long?

"If you had told me earlier, I would have helped you solve it."

"Sister Qin, do you have a way to solve it?" Shen Nianzhi immediately became energetic.

"Think about it, over the years, every action the princess has taken has been filled with profound meaning. And has she ever made a wrong decision?"

"Of course not!" Shen Nianzhi said immediately, "The princess is not only talented, but also has a compassionate heart.

“Over the years, the princess not only let us study, but also taught many women to read, write and do accounting, and she has been working hard to help them get opportunities to work and earn money.

"Everyone is extremely grateful to the princess. I don't know how many people lit candles in front of the Buddha in Huangjue Temple on the outskirts of the city for her!"

"So, since the princess not only allowed these two people to board our ship, but also asked them to hand over the method of making glass, it proves that this thing must be valuable!"

Sister Qin’s words instantly awakened Shen Nianzhi, and her eyes suddenly lit up.

"Yeah, why didn't I think of that?

"Then I'll go tell the princess that I want to learn how to make glass from those two!"

Shen Nianzhi had been struggling with this for several days, and when he finally figured it out, he didn't want to waste any more time and went straight to the upper cabin to ask to see the princess.

At this time, Qingtian and Qin Hexuan were studying the glass that had just been delivered by the two craftsmen in the hall.

There were several relatively flat glass plates on the table. On a sunny day, I would hold them up to the light one by one and tap them lightly with my hand to test their hardness.

Qin Hexuan watched anxiously from the side, and quickly took it from her hand and said, "If you want to do something, just ask someone to do it. Why do you have to do it yourself? If this thing breaks, you will be hurt. What will you do?"

"Alas, it's still too thick and too small, and there are a lot of bubbles inside."

Qingtian was a little disappointed. Western glassmaking technology was indeed much better than that of Da Qi. Nowadays, all glassware in Da Qi was still called "Liuli". The more exquisite it was, the more expensive it was.

These craftsmen who specialized in making glass were only good at making exquisite and small objects, but they could not make the smooth, uniform and transparent glass plates that she wanted.

Qin Hexuan looked at the glass plate over and over for a long time and asked, "What on earth do you want to do?"

Qingtian held up another piece of glass, walked to the window and gestured, "Brother Qin, have you ever thought that if we replace the window paper on the windows with glass, the house will be brighter in the future?"

Qin Hexuan's mind was still confined to the knowledge that glassware was very expensive, and he had never thought that it could be used for this purpose. When he heard Qingtian's words, he instantly became interested.

"If the window paper on the study windows could be replaced with glass panels, Master wouldn't have to work so hard to read in the study during the day."

"Right!" Qingtian said happily when he saw that Qin Hexuan finally understood his idea, "Before, I was in the palace and saw a clock that was a tribute from the West. It had a metal frame and a glass cover on the outside. Whenever the sun shone on it, it would not only illuminate the clock inside, but also create a colorful halo.

“I thought, ‘It would be great if I could have windows like this in my room.’”

Thinking about the cost of the glazed cover in the emperor's palace, even Qin Hexuan, who is now wealthy, couldn't help but gasp.

"You're so bold!"

"Hey, isn't this already possible now?" Qingtian said, looking at the glass plates on the table, "Western glass is cheap and easy to make, but they've never made anything like this before.

“I believe that as long as I tell them my needs and let them experiment a few times, they will be able to make glass plates that satisfy me.

"When the time comes, I'm going to replace all the window paper in the Princess's Mansion with glass!"

After hearing Qingtian's words, Qin Hexuan looked at the glass plate in his hand with a much more serious look.

"Not only are there a lot of bubbles in the glass now, but there are also a lot of cracks. This is really too dangerous."

Qin Hexuan said this and snapped his fingers.

There was only a crisp sound, and the glass in his hand shattered.

"Look at you, you told me to be careful, but you are so careless yourself."

Qingtian quickly called the servants in to clean up the broken glass on the table and the floor.

Just at this moment, Shen Nianzhi came over.

"Your Highness, I would like to learn from those two glassmakers."

"Really?" Qingtian was immediately delighted when he heard this. He grabbed her hand and said, "Then I have to tell you my thoughts..."

Even Qin Hexuan beside him looked at her.

Shen Nianzhi didn’t expect that he would be treated like this, he was flattered.

Sister Qin was right. Glass, which even the princess and Young Master Qin valued so much, must have a lot of uses and could not be limited to being used as decoration.
