This time, Yi Zilan personally took the paper and presented it.

The emperor looked suspicious, opened the paper to look at it, and after looking at it for a while, he was even more confused, "This is ......"

Yi Zilan said, "Your Majesty, what is written on this paper is the recipe for making this magnifying glass." ”

"What did you say?" The Emperor raised his head in surprise and looked at his cousin in dismay, who had lowered his voice in front of him.

He asked a little excitedly, "Really?" What can we do ourselves with this magnifying glass? Quick, tell me more. ”

"Yes." Yi Zilan arched her hand and said slowly, "Then Mrs. Shao said that she inadvertently made up this magnifying glass. Because I didn't take it seriously when I made it, I didn't pay attention to it, so I only made this one. When she found out that the magnifying glass was so useful, she tried to do it again, but she never succeeded, and she didn't know which step was wrong. But the materials used at that time, Mrs. Shao wrote on this piece of paper. She said, if we want to make a magnifying glass, we can try it by following the steps on this paper......"

The emperor pondered as he listened, that is, the specific process and materials of this magnifying glass were not very certain.

"So what is written on this paper is also a general method, and we need to work how to do it?"

Yi Zilan nodded, "That's what Mrs. Shao said. ”

In fact, Gu Yundong really didn't know how to make a magnifying glass, and when she was an intern in her last life, she followed her to visit the declining old craftsmen.

At the beginning, the man told her that the glasses at the beginning of ancient times were magnifying glasses and convex lenses.

He had done it once in front of Gu Yundong, so Gu Yundong had an impression of the process and materials, but she had never done it herself.

To put it bluntly, she can only talk on paper.

The craftsman of the latter gave Gu Yundong the finished magnifying glass, and in order to fit the ancient craftsmanship, this frame was inlaid with a turtle shell, which was the pair in front of the emperor.

After the end of the world, Gu Yundong put all the things in his house into the space, including this magnifying glass.

Now she has written everything she saw at the beginning and handed it to Yi Zilan, of course, after all, it is a memory from many years ago, and there may be some omissions or additions.

But Gu Yundong believes that with those skilled craftsmen and skilled people under the emperor, as long as they give an idea, they can create the future. More research and research will definitely make a magnifying glass, and even worse, maybe there will be an unexpected gain, even the glasses will be made?

Gu Yundong was full of confidence in them.

Indeed, even if the material is not very certain, it is a huge surprise for the emperor.

His hand gripping the paper tightened slightly, and he sighed with a smile, "This Gu Yundong can always bring good luck to me, and he is a talent." No, it's the two of them, both of whom are nobles of mine. ”

This time, Yi Zilan was very sure that she had indeed heard the emperor's cousin call out Gu Yundong's name, and she was also very sure that she was talking about Mrs. Shao when she mentioned her.

And listening to the emperor's meaning, he seems to be quite familiar with Gu Yundong? Always??

What else did Gu Yundong bring?

Yi Zilan couldn't help it, but still stepped forward in a low voice and asked, "Your Majesty, do you know Shao Qingyuan's wife?" Know her name? ”

The Emperor folded the paper and carefully placed it in the box containing the magnifying glass.

After covering it, he raised his eyes and glanced at Yi Zilan.
