"Your Majesty, I... is this a kind of eye disease?"

"That's true! Not really..."

Faced with the old man's problem, Ying Feiyu smiled and then handed over his glasses, "Put this thing on the bridge of his nose and hang it on his ears!"

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

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

All the onlookers held their breath and stared at the old man intently, wanting to see what would happen.

"Hmm? What's going on?"

The old man grabbed the newspaper, as if he was very shocked.

Ying Feiyu smiled carelessly, "How?"

"This...this...how is this possible? It's obviously the same newspaper?"

The old man flipped the newspaper back and forth and checked carefully, "Why did it suddenly become very clear when the distance is still the same?"

"It's become clearer? Could it be the function of those two lenses?"

"Is that necessary? That's for sure!"

"It's easy to cure the old man's eye disease? Isn't this amazing...?"

Watching the craftsmen were quite shocked to see this scene.

"You've sure it's clear?"

Ying Feiyu asked inquiries.

"Confirm! Very sure!"

The old man looked particularly excited as his eyes returned to clear light.

"Just at the current distance, maybe copy the words on the newspaper?"

"Yes! Yes! Sure!"

The old man nodded repeatedly.

The wink-eyed craftsman quickly brought paper and pen, and the old man wrote a few according to the words in the newspaper.

"Oh! I've really written it out! It seems that I've really read the words on the newspaper!"

"That's for sure! When did the things Your Majesty study go wrong?"

"This thing is so amazing..."

The craftsmen witnessed the magical effects of glasses with their own eyes and praised them.

"Your Highness, what is this? Why did the originally vague thing suddenly become clear after wearing it?"

The old man dared not take off his glasses without authorization, and pointed at the stuff on his nose and asked in surprise.

"This is called glasses, which can regulate your vision! In this case, it is because of your age. After adjusting with glasses, it will naturally become clear!"

Ying Feiyu explained it briefly.

"This is amazing! Now it's clear to His Majesty and everyone's faces!"

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

"Well! That's right! These glasses were created for the Supreme Emperor! When I go back and produce in large quantities, I will give you one too!"

Ying Feiyu said with a smile.

"Yo! Yo! Yo! The people dare not, the people dare not!"

The old man waved his hands repeatedly and gently took off his glasses.

This is for the Supreme Emperor. It would be good if he was lucky enough to wear it once, so how dare he continue to wear it?

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

Huang Zimo was like his uncle. When he heard that he wanted to produce fresh things, his eyes were brighter than anyone else.

"That's right! There are many people with myopia and blurred eyes in Daqin! Glasses can effectively regulate vision, and it does require mass production!"

Ying Feiyu nodded confidently, "Now I will tell you the principles and manufacturing methods of glasses..."

If you want to make glasses in large quantities, these craftsmen will inevitably be indispensable.

Taking advantage of the time today, we will popularize relevant knowledge and start production tomorrow.

If you give birth one day earlier, you can get people to wear glasses one day earlier!

...

After the morning court the next day, Ying Feiyu came to Yuxiu Palace with light steps.

Before entering the main hall, I saw Ying Zheng pacing back and forth in the house with his head down.

It seemed that he heard the movement, so he stopped and complained: "You kid is really slow, why did you come here at this time?"

"Where is the stuff?"

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

"Shouldn't the father let the son in the door first?"

Ying Feiyu was in a good mood, but after being disturbed by this old guy, he suddenly felt completely out of mood.

"Where did you come from so much nonsense? Hurry up..."

"Brother Zheng! How can I let my children talk outside the door?"

Ying Zheng urged impatiently, but after he was halfway through, he was interrupted by Lian'er who rushed over after hearing the sound.

"snort!"

When a mother spoke for him, Ying Feiyu raised her head, snorted coldly, deliberately hitting Ying Zheng's shoulder with half of her shoulder, and staggering him.

"you……"

Just as Ying Zheng wanted to insult him, he saw Lian'er's back warmly greeting her son, so he choked back the second half of the words he didn't say.

There is no way, I still have a request for this kid later, so it’s better not to offend this guy first!

He rubbed his shoulders, pulled his face, and muttered, walking towards the table, "Is your kid's body made of stone?"

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

Ying Feiyu leaned on the chair, crossed his legs, leisurely took out an exquisite small box from his arms and put it on the table.

This is a glasses box specially redeemed from the system.

The reading glasses just made are among them!

"This...this is what you guy said, can I see clearly?"

After Ying Zheng saw this, he immediately shut up and stopped caring about the previous events.

But after picking up the box and checking it carefully, he frowned, "This thing looks good, but it seems to be a bit different from what you 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 to achieve the purpose of seeing clearly!

But now it seems that it is not that way!

"If the father was willing to put in more effort and open the box, he might understand!"

Ying Feiyu is sarcastic and has a sarcastic meaning in his words.

"Ah? Open?"

Ying Zheng didn't think about this at all. After he said this, he looked for a slightly embarrassed way to open the box.

After fiddling with the box in his hand for two rounds, he finally found the trick. He gently fiddled with one side of the box, and the magnetic lid was opened, "Hmph! Didn't you say it earlier!"

He gently pinched out the things inside, and a smile appeared on the corner of Ying Zheng's mouth, "This thing... looks pretty good!"

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

So light as if nothing!

It can be taken away by putting it in a small box, which is much more convenient than a telescope!

"Brother Zheng, try it now!"

When Lian'er saw that she had studied the things, she was very happy and immediately brought today's newspaper.

"Hehe! Just to test this thing, I didn't even read today's newspaper!"
Chapter completed!
