"Your Majesty, old and decaying...... But is it an eye disease? ”

"Sort of! It's not a ...... either! ”

Facing the old man's question, Ying Feiyu smiled and spoke, and then handed over the glasses, "Put this thing on the bridge of your nose and hang it on your ears on both sides!" ”

I simply taught how to wear glasses, and the old man understood it as soon as he heard it, so he quickly put the glasses on!

Ying Feiyu once again placed the newspaper in the position where the old man said he couldn't read clearly for the first time, "Look at it now!" ”

The onlookers all held their breath and stared intently at the old man, wondering what would happen.

"Huh? What's going on? ”

The old man snatched the newspaper as if he were shocked.

Ying Feiyu smiled casually, "How?" ”

"This ...... This...... How is this possible? It's the same newspaper? ”

The old man flipped the newspaper back and forth, and carefully checked, "It's still the same distance, why is it suddenly so clear?" ”

"Clearer? Could it be the effect of those two lenses? ”

"Needless to say? That's for sure! ”

"Easily cured the old man's eye disease? Isn't that amazing......? ”

The onlookers were shocked when they saw this scene.

"Are you sure it's clear?"

Ying Feiyu asked.

"Sure! Pretty sure! ”

His eyes returned to clarity, and the old man looked particularly excited.

"At the current distance, it is possible to transcribe the words in the newspaper?"

"Yes! Yes! Absolutely! ”

The old man nodded repeatedly.

The eye-catching craftsman hurriedly brought paper and pen, and the old man wrote a few according to the words in the newspaper.

"Yo! It's really written! Looks like I can really read the words in the newspaper! ”

"That's for sure! When did the things that His Majesty studied go wrong? ”

"This thing is amazing......!"

Craftsmen have witnessed the miraculous effects of glasses and have praised them.

"Your Royal Highness the Prince, what the hell is this? Why does after wearing this thing, the originally vague things suddenly become clearer? ”

The old man didn't dare to take off his glasses without permission, so he pointed to the thing on the bridge of his nose and asked in surprise.

"These are called glasses, and they can adjust your vision! And in your case, it is presbyopia caused by age, and after adjusting it with glasses, it will naturally become clear! ”

Ying Feiyu explained simply.

"It's amazing! Now look at the faces of His Majesty and everyone, it is very clear! ”

The old man happily glanced around, and could see everyone's face clearly.

"Hmmm! That's right! These glasses were made by me for the Emperor! When I go back to mass production, I will give you a pair too! ”

Ying Feiyu smiled.

"Yo! Yo! Yo! The grass people don't dare, the grass people don't dare! ”

The old man waved his hand again and again, and gently took off his glasses.

This is for the Emperor, he is lucky enough to wear it once, how dare he continue to wear it?

"Your Majesty, these glasses are going to be mass-produced?"

Huang Zimo, like his uncle, when he heard that he was going to produce new things, his eyes widened brighter than anyone else.

"That's right! There are not a few people who are short-sighted and blinded in my Daqin! Glasses can effectively adjust vision, and they do need to be produced in large quantities! ”

Ying Feiyu nodded firmly, "Now I'll tell you about the principle and manufacturing method of glasses......!" ”

If glasses are to be manufactured in large quantities, these craftsmen are indispensable.

Take advantage of the free time today, popularize the relevant knowledge, and start production tomorrow.

The sooner you give birth, the sooner you can let the people use glasses!

……

After the morning of the next day, Ying Feiyu came to Yuxiu Palace with brisk steps.

Before he could enter the gate of the main hall, he saw Yingzheng pacing back and forth in the house with his head down.

seemed to hear the movement, so he paused and complained: "You kid is really grinding, why did you come over at this time?" ”

"Where's the stuff?"

After the old guy greeted him, the first thing he said was not to let Ying Feiyu in, but to stretch out his big hand and make a request.

"Shouldn't my father let his sons in the door first?"

Originally, Ying Feiyu was in a good mood, but when he was disturbed by this old guy, he was in no mood at all.

"Where did you kid get so much nonsense? Hurry up and ......"

"Brother Zheng! How can there be any reason for children to talk outside the door? ”

Yingzheng urged impatiently, but he was only halfway through his words when he was interrupted by Lian'er, who rushed to hear the sound.

"Humph!"

With his mother speaking for him, Ying Feiyu tilted his head, snorted coldly, and deliberately bumped half of his shoulder into Ying Zheng's shoulder and knocked him to a stumbling point.

"You ......"

As soon as Yingzheng wanted to insult him, he saw Lian'er's back greeting his son warmly, so he choked back the words that he didn't say again.

There's no way, I'll still ask for this kid later, so it's better not to offend him first!

Rubbing his shoulders, pulling his face, he muttered as he walked towards the table, "Is your kid's body made of stone?" ”

"The body of the son is not made of stone, but the father is negligent in exercising!"

Ying Feiyu leaned back on the chair, crossed Erlang's legs, and leisurely took out a beautiful small box from his arms and put it on the table.

This is a glasses case that is specially redeemed from the system.

Freshly made reading glasses are among them!

"This ...... That's what you kid said, what I can see? ”

After Ying Zheng saw it, he immediately shut up and no longer cared about what happened before.

But after picking up the box and examining it carefully, he frowned, "This thing is good-looking, but it seems to be a little different from what your kid said before!" It doesn't seem like a telescope! ”

According to Ying Feiyu's description yesterday, he imagined that it should be a modified telescope that can adjust the distance back and forth, so as to achieve the purpose of seeing clearly!

But now, it seems, it's not like that!

"If my father is willing to put a little more effort into opening the box, maybe he will understand!"

Ying Feiyu has a strange yin and yang, and there is a sense of ridicule in his words.

"Huh? Open it? ”

Ying Zheng didn't think about this stubble at all, and after he said this, he was slightly embarrassed to find a way to open the box.

After fiddling with the box in his hand twice, he finally found the trick, gently fiddling with one side of the box, and the magnetic lid was opened, "Hmph! You kid didn't say it sooner! ”

Gently pinched out the contents inside, and the corners of Ying Zheng's mouth immediately showed a smile, "This thing...... Looks pretty good! ”

I knew that this kid would improve something similar to a telescope, but I didn't expect it to be improved to such an extent.

It's as light as nothing!

Put it in a small box and take it away, which is much more convenient than a telescope!

"Brother Zheng, hurry up and try it!"

Seeing that the things were studied, Lian'er was also very happy, and immediately brought today's newspaper.

"Hey, hey! Just to test this thing, I didn't even read today's newspaper! ”

Ying Zheng happily took the folded glasses and brought them to the newspaper.
