Bai Yixiu didn't think much of the complaint of Huainan king and had long thought of countermeasures.

"Uncle seven, I really didn't lie to you. The reason why I agreed to Gu's little uncle's request was that old lady Gu was too old to go to the shop.

But you and my seventh aunt are young people. There are not only good things like glasses, but also skin care products and hair care. Anyway, there are many good things, and my seventh aunt will like there. "Bai Yixiu can't cry or laugh. Huainan Wang is really annoying.

The king of Huainan listened and was half convinced. "Didn't you lie to me?"

"The shop is right there. You'll know when you see it." Bai Yixiu hurriedly said, "I'll greet uncle seven myself. Is that ok?"

"It's almost the same. I don't need money, but I must give me good things." Huainan Wang was happy. If Bai Yixiu didn't cheat him, he wouldn't care.

While Bai Yixiu and the king of Huainan were talking, Gu juecheng looked curiously at Prince Bai Yishan, opened a rectangular box and took out a dark, thick and small cylinder.

Prince Bai Yishan looked up and down and saw that there were glass mirrors at both ends of the cylinder. Then he habitually put the small end on his eyes. At this look, he was stunned and tongue tied. He couldn't believe it.

Gu juecheng was very surprised when he saw the prince's expression and asked curiously, "prince, what do you see?"

"I... I saw the birds on the trees in the yard," said Prince Bai Yishan excitedly, "it's very clear

Hearing this, Gu as like as two peas, he immediately opened another box, which was just like the prince's Royal Highness, and put out a cylinder from it.

He looked at it like the prince, and he was stunned, stunned and unbelievable.

Huainan Wang didn't understand, "what's the significance of seeing the birds in the tree? I can see them, too."

At this time, Bai Yixiu turned his head and saw that the two telescopes had been held by the prince's brother and Gu juecheng. From their shocked expressions, they should have found the wonderful use of the telescopes.

Gu juecheng, in particular, is a military general. He needs such tools on the battlefield.

"Hehe, seventh uncle, you haven't seen anything. This is a telescope I've developed. You can see things far away!" Bai Yixiu said proudly.

Although it was made in imitation of his previous life, he was the first to make it in Dazhou. Let's take it as his invention, otherwise Bai Yixiu doesn't know how to explain where these things come from.

"The bird's eyes, claws and even feathers can be seen clearly." Jinghai Wang said excitedly. "If such a good thing is used in the battlefield, it is simply a sharp weapon of the general."

Emperor Kangming was surprised to see that Gu juecheng, who was usually calm and serious, became so excited at this time

When he was on the battlefield, he naturally understood the advantages of being able to see far and clearly, so he grabbed the telescope directly from the prince's hand and began to look out.

"Good, good!" emperor Kangming was overjoyed. This is a good thing!

The king of Huainan dared not grab the telescope from emperor Kangming, so he couldn't wait to grab it from Gu juecheng. But Gu juecheng stretched out his arms very well. He just turned sideways and was thrown into the air by the king of Huainan.
