Zhou Yizhi looked at her in shock.

Anything better?

What does that look like?

She couldn't think of it.

"Yun'er, where have you seen it?" she asked softly.

Yun Dai was silent for a moment and smiled and said, "Is that a long time ago, the place... I can't remember it."

The days of the previous life are indeed gradually distant.

Zhao Shu stood not far away, listening to her words, with a quiet expression.

Over the past year, although they did not discuss directly, and the emperor passed the message, Zhao Shu was also curious when he looked at her drawings.

What she has experienced, where she has been, and why did she understand these things?

Zhao Shu can be sure that the second lady of the Gu family had never left the Gu family for fourteen years before entering the palace.

In the Gu family, she is just a little pitiful person who is not favored and has a quiet personality.

Where can I get access to these firearms?

But this is all her privacy, and Zhao Shu will never take the initiative to inquire.

At most, doubts flash in my heart occasionally.

Yun Dai asked someone to take a magnifying glass, check the fifty cannons from the beginning to carefully.

This magnifying glass was ground with crystals and was made by her masters at the glass workshop.

As soon as this thing was brought, it was loved by many people.

Including Zhao Shu, he also asked the master of the glass workshop to make two pictures, one in the study and the other in the factory.

Seeing that so many people liked it, Yun Dai drew a drawing for Master Wang and asked him to do it as follows.

Lao Wang looked at the strange thing on the drawings and couldn't help asking: "Madam, what is this?"

"Glasses."

"Glasses?"

"Wearing with your eyes, aren't there many people's eyes that are not good, such as young people, who can't see things clearly when they are far away. For example, you are old and cannot see things nearby. As long as you wear these kinds of glasses, it can be solved." Yun Dai explained carefully, "Of course, myopia glasses and hyperopia glasses are different."

Master Wang seemed to understand it, but it did not prevent him from making the things in full.

I heard that it has been made, and Yun Dai hasn't seen it yet.

Have been too busy lately.

I didn't even care about the glass workshop.

After checking the fifty cannons, she randomly selected three and said she wanted to pull them outdoors for testing.

Zhao Shu immediately called someone over and used a flatbed cart to pull the cannon to the open area outside to conduct a firing test.

Zhou Yizhi remained excited and even reached out to help pull the cart.

It made several soldiers rush.

Yun Dai let her go.

She is the one who wants to go to the military camp and will deal with a group of powerful soldiers every day in the future. What is this little thing?

The soldiers pulled the cannons into the open space, and Zhao Shu asked someone to bring in ten shells.

"Queen, stand a little further." Zhao Shu said, "I'm going to start firing the cannon."

Yun Dai said: "Prince, can you let me give it a try?"

Zhao Shu glanced at her, thought of her wrists wrapped in gauze in her sleeves, and frowned and said, "Can you do it?"

"It's just ignition, what's wrong with it?"

Zhao Shu took out two balls of cotton from his purse and gave it to her: "Put it into his ears."

Yun Dai couldn't help laughing: "It's not that I exploded in my ears, so I can use this anywhere. I just want to feel the situation when the cannon was launched at a close distance, and then calculate the stability and range of the cannon. Isn't this the purpose of my visit here today?"
