Datang: Stop pretending, you are a peerless expert

yard,
Su Yu made four pairs of glasses.

"Come on, try it."

Su Yu gave the glasses to Li Shimin and the others.

Li Shimin put on his glasses and suddenly felt alive again.

After the three of Fang Xuanling put it on, they were overjoyed.

I can finally see clearly.

Since they were in their 20s, they have used their eyes excessively, especially reading books at night, which hurts their eyes the most.

Only today did I have the feeling of regaining the light.

Miaozai, cool too.

"Old Fang, this is the first time I see you so clearly."

Wei Zheng laughed.

"Yeah, I just realized you're so dark."

Fang Xuanling laughed.

Wei Zheng was not angry at all.

It feels so good to wear glasses.

Du Ruhui said: "With glasses on, playing mahjong will definitely be smoother."

"Yes, for sure."

Wei Zheng agreed.

He won a 70-jin gold bar last time, and he has infinite enthusiasm for playing mahjong.

The queen is fighting the landlord with Changle and Xiaosizi.

Chang Le turned her head and said contemptuously: "You are all behind the times, fighting the landlord is popular now, not playing mahjong."

When Wei Zheng heard that mahjong was not popular, he became anxious.

"Mr. Su, mahjong is no longer popular, so can the second Sparrow God Competition still be held?"

Wei Zheng is also counting on winning again and taking the ranking so that he can retire with peace of mind.

"The Sparrow God Contest, it depends on Lizhi, she can fight if she wants to win, and stop playing if she doesn't want to win."

Su Yu said.

Originally, the second session was held just to appease Princess Changle.

Now Changle seems to be interested in Doudizhu.

Then there is no need to hold the Sparrow God Competition.

Wei Zheng looked at Princess Changle eagerly.

"Miss, my old Wei hopes to get some bonuses so that I can save some retirement money."

Seeing Wei Zheng's pitiful look, Changle said, "Then let's hold it, and I'll give you another win."

Li Shimin looked sour from the side.

This Wei Zheng, I can't do anything with him, a sparrow god competition in Changle made him submissive.

"Thank you, miss, for your kindness."

Wei Zheng was overjoyed.

"Master Su, Missy said that it will be held, do you see?"

Wei Zheng smiled shyly.

"Let's do it then."

Su Yu said casually.

"Thank you Su Gongzi."

Wei Zheng was overjoyed.

Having said all that needed to be said, Li Shimin began to speak: "The three of you go to Mr. Tony's place to wash your hair, and go now."

Mr. Tony?What Mr. Tony?

The three of Wei Zheng were just like Li Shimin a few days ago, they were dumbfounded.

"Your Majesty, who is Tony's wife?"

"Why did Master wash our hair?"

Li Shimin pretended to be impatient, and said: "Tony is a big dog who washes his hair, Ergouzi and his brother, turn left when you go out, there is a big dog in shape."

Su Yu went to watch the three queens play cards, ignoring Li Shimin's costume competition.

"It turned out to be that one, I saw it when I came in just now."

Wei Zheng chuckled.

It turns out that the person who washes his hair is called Teacher Tony, who has a lot of knowledge.

The three of them went to wash their hair immediately.

After more than an hour, the three of Fang Xuanling wore smooth hair.
That is to say, Du Ruhui's hair volume is not bad, Fang Xuanling and Wei Zheng have both become stronger and bald.

"How do you three feel about the shampoo shop?"

Li Shimin asked.

Wei Zheng said: "Very good, it's wonderful."

"Weichen's hair has never been so smooth."

Du Ruhui sighed: "Today I know that washing your hair is a kind of pleasure, that's wonderful."

Fang Xuanling sighed: "After washing my hair, I feel much more comfortable, and my scalp doesn't itch anymore."

Li Shimin said: "I think it is possible to open a shampoo chain store in Chang'an City. Think about it, what a business opportunity this is."

Du Ruhui immediately said: "The shopkeeper has good eyesight, this is indeed a good business."

Li Shimin smiled triumphantly: "Of course, my brother also thinks this business is good."

"There is a second business."

Li Shimin continued.

"Brother, let me discuss something with you."

Without looking back, Su Yu replied, "Speak."

"I found that there are many people in Chang'an City who are short-sighted, and they are all officials. They are rich."

"We open an optical shop, and the business must be good."

Li Shimin said proudly.

This time I feel like a business genius.

Whether it is an optical shop or a shampoo shop, it is an excellent business.

Su Yu smiled and said, "There are not many people with nearsightedness, but there are many people with presbyopia."

"If you want to open an optical shop, you'd better sell them together."

There are many scholars in modern society, and there are many myopia.

But the ancient society was different, and the number of scholars was really not many.

But there are many elderly people, and there is a great demand for reading glasses.

"Brother, can presbyopia be worn?"

Li Shimin said strangely.

"Yes, but it's not myopia glasses like this, but reading glasses."

Su Yu said.

"My dear brother, what kind of reading glasses are you?"

Li Shimin walked over, knelt down and asked Su Yu.

"Reading glasses are convex lenses."

Su Yu said.

Concave lenses are used for myopia, and convex lenses are used for presbyopia. This is the most basic physics knowledge.

The teachers at Lanxiang School must have talked about it.

But Li Shimin didn't learn it, he didn't know.

"Master Su, what is a convex lens?"

Wei Zheng asked.

This is too much trouble to explain.

"No need to ask, I will give you some reading glasses tomorrow, and you will know by then."

Su Yu said.

"Also, I will give you another manual to teach you how to make glasses and how to measure the degree of myopia."

Just giving them lenses is definitely not enough.

"Thank you dear brother."

Li Shimin laughed.

"Thank you, anyway, I share the big head."

Su Yu giggled.

Li Shimin's smile gradually disappeared
The next day, Su Yu made some reading glasses.

"This one is for those who can see things in the distance, but can't see things in front of them."

Su Yu simply explained.

This makes it much clearer.

"Understood, thank you."

Li Shimin and the others returned to Chang'an City.

Tai Chi Hall,
Li Shimin sat on the court hall.

The officials below stand on both sides, divided into civil and military.

Cheng Yaojin hid behind Qin Qiong, not daring to look at Li Shimin.

At the beginning of court, Li Shimin took out another brocade box, took out a pair of glasses from it, and slowly put it on.

The ministers in the court exclaimed: "The emperor still has glasses?"

Just when the officials exclaimed that Li Shimin was still there.

Du Ruhui, Fang Xuanling, and Wei Zheng took out their glasses from their sleeves and put them on slowly.

The degree of showing off is like a billionaire showing off his wealth in the slums.

"Mr. Xing, why do you have glasses?"

Zhangsun Wuji asked.

He has never seen this uncle of the country, but now Fang Xuanling has one.

"Cai Guogong, where did you come from?"

Yu Shinan asked in surprise.

Isn't this something that only the emperor can afford?
Wei Zheng was not happy.

Why no one asked me?
Li Shimin gave a dry cough, and the court fell silent.

Li Shimin said, "Where is Duke Lu?"

Cheng Yaojin stepped out bravely.

"The guilty minister is here."

Broken Li Shimin's glasses, Cheng Yaojin panicked.

"Come on, this is for you."

"Wear this and your presbyopia will be cured."

Li Shimin took out a box.

Eunuch Gao picked it up, stepped off the stage, and handed it to Cheng Yaojin.

With doubts, Cheng Yaojin opened the box, the glasses were the same, they looked the same.

"Your Majesty, if I wear this dizzy one, it will break."

Cheng Yaojin said.

Li Shimin smiled slightly and said, "No, this is just right for you to wear."

Holding the glasses, Cheng Yaojin said to Qin Qiong, "Shu Bao, help me."

Qin Qiong supported Cheng Yaojin, afraid that he would fall.

Putting on the reading glasses, Cheng Yaojin was stunned.

Really good.

"Thank you, Your Majesty."

Cheng Yaojin was overjoyed.

The ministers of the DPRK and China were shocked.
