"What is this?"

Ying Zheng took the small cylindrical cylinder handed by his daughter, his eyes full of curiosity.

"I call it a telescope, or a claireye, and I only make two of them in my workshop."

Xu Yan said casually, "If my father wants to, I have to send someone to the craftsman's workshop to practice." ”

In fact, she found these two miniature telescopes from the office of an old professor at the Academy of Agricultural Sciences who loved astronomical observations.

It's just that I've never had a chance to use it before.

As for where does the material come from? Naturally, Xu Yan returned to Daqin from modern times and began to prepare.

At the same time as the sweet potatoes and corn were planted, a craftsman's workshop was arranged, and a small kiln was made, firing glass, and polishing it into a convex lens.

It also happened that in the craftsman's workshop of Huazhang Palace, she barely managed to get out two bulky telescopes the day before yesterday, and she responded to her father with this.

Anyway, she said that she was making two, and she didn't say that it was these two.

As for whether taking out this thing will make Zu Long suspect anything, Xu Yan is confident.

After all, the drunken words on the twenty-ninth day of the lunar month still have a vague impression after waking up the next day.

Since he said so much that day, and his father didn't ask any relevant questions these days, it should be okay to try to come up with something else.

Sure enough, Zu Long didn't ask much when he took this magical thing, and his slightly hanging heart secretly relaxed.

While speaking, she took the telescope in her hand and demonstrated it to Zu Long: "Father, put the little one in front of your eyes and close the other eye, and you'll be fine." ”

"Oh, I'll try."

Ying Zheng looked like a girl and looked over.

"Hiss~~~~"

At first glance, seeing the distant scenery appear in front of him, even the ancestral dragon couldn't help but gasp.

"Father, don't be nervous, this is the purpose of the telescope, it can bring things in the distance closer for you to see." ”

"If you think it's too close, you can adjust it here."

Xu Yan carefully demonstrated the use of the telescope to his father, and Zu Long quickly learned it.

"It's a good thing, you can see things that far away."

Ying Zheng sighed, "I can actually see the distribution of Wang Ben's troops!" ”

She smiled and didn't answer.

At this moment, she was observing Zhang Han's hiding place, well, at first glance, she really couldn't find it, but if she looked closely, she could still see where they were hiding.

"Huh? Zhang Han, where did they go? ”

At this moment, my father's voice sounded in my ears, "Why can't I find them?" ”

"Father, if you find them too easily, won't it be in vain for me to teach them the new art of war?"

Xu Yan smiled brightly, "Anyway, you have to believe that they haven't crossed the line of deployment that you have drawn for the rest of your life." ”

"You'll know how they're going to fight when the battle begins."

"Hehehe...... It seems that Xu'er is very confident. ”

Hearing the confident voice of the nine girls, Ying Zhengle was harmonious, "I'm afraid that they have only learned a little tricks, but in the end they are nothing." ”

"Hmph, Father, wait and see."

Xu Yan didn't realize that her words and deeds in front of Zu Long were a little childish.

She knew that her father was deliberately teasing herself, but she couldn't help but be angry with him.

"Your Majesty, can you let the ministers also watch the situation of the two sides of the battle?"

Wang Jian listened to the father and daughter and looked at the strange thing in their hands, and he was already itching.

Seeing that the father and daughter only cared about talking, but did not carefully observe the situation of the two sides of the battle, he couldn't help but make his request.

Ying Zheng: "Don't worry, it hasn't started yet." ”

Just kidding, he hasn't used enough of this thing, how can he use it for others? (End of chapter)
