"Young man, do you need anything?" An old man sat behind the counter. After watching the communication between Li Muyun and the mate, he asked him with a smile.

Li Muyun smiled and nodded to the old man: "I need two black crystals, which are the ones with the best light transmission. Do you have them here?"

No matter how the old man looked at him, at least this old guy had no contempt in his eyes, only peace, which was the most satisfying thing to Li Muyun, so he gave up the idea of ​​pretending to be a silly and planned to do the important things first.

The old man frowned slightly, thought for a while and said, "This young man, there is indeed a black crystal old man in the shop, but I don't know what the light transmittance you are talking about?"

"It's just transparent. Look at things through the crystal. The clearer the better." Li Muyun said with a smile.

"This..." The old man seemed a little uncertain and hesitated for a moment: "I'm going to tell you that your request is too vague. I don't know if the black crystal in the store is up to your wishes."

Li Muyun was not polite, and tapped his fingers on the counter and said, "Then take it out and take a look. If you are satisfied, I will leave a look. You still need to process it for me here."

The old man was not that happy this time. He hesitated for a moment before nodding and said, "Okay, young master, wait a moment." Then he said to the mate, "You go back and get two black crystals."

"Wait a minute, I'll have the same color." Seeing that the mate agreed, Li Muyun walked behind the store and quickly gave a message.

...

After waiting for about a quarter of an hour, the guy who had just left came back again, holding a tray in his hand, detoured the back of the counter, and placed the tray in front of the old man and Li Muyun.

I have to say that in the Tang Dynasty, crystals were really purely natural, and the only thing related to people was collection and polishing. This is what made Li Muyun most relieved because he didn't have to worry about buying fakes himself.

Moreover, the two crystals on the tray do meet his requirements, both in color and light transmission, and it seems that the two crystals should have been one piece, and some of the positions can even be combined together.

"Young master, how about it? Are you still satisfied with the stuff?" The old man couldn't help but ask. Seeing that Li Muyun was just watching there and had no intention of picking it up.

"I want to polish these two pieces of crystals and turn them into two thin sheets, the thickness should be equivalent to that of the copper coin, it looks..." Li Muyun roughly mentioned his requirements, including the appearance and shape of the crystal that needs to be polished, and a pair of brackets.

The weather is getting hotter and hotter, and the hot sun makes people feel uncomfortable, so Li Mu naturally thought of sunglasses made of crystal lenses.

Not only does it bring a cool feeling to your eyes, but it also has the function of pretending to be a calves. It is really a must-have item for home travel.

"Young Master, the small shop can do all the things you said, but the price is this..." After hearing Li Muyun's request, the old man thought about it first, and then continued.

"Tell me, how much is it?" Li Muyun did not let the old man finish his words, and took over the conversation directly.

"If you do it all as you said, it will cost two stale and five hundred cents. If this price is..."

"Okay, two silos are just two silos and five, girl, give it money." Li Muyun didn't expect to buy crystals in Datang to be cheap. After all, due to the difficulty of mining and polishing technology, the price of this thing is completely incomparable to later generations, let alone making a pair of glasses frames.

Although the little girl Mu Yu felt that Li Muyun had lost money after spending two "broken stones" after spending two "broken stones", she still said nothing and took out some scattered silver from her purse and put it on the counter.

The old man obviously never thought that Li Muyun would pay so happily. He originally wanted to pay some deposit, but now he seemed to have no need to say anything.

Moreover, Li Muyun seemed to have no intention of leaving after picking the crystal, but knocked on the table, awakening the old man and the guy from surprise: "Do you have a good hairpin? Pick a few and match this girl."

"Ah?" The little girl Mu Yu originally thought that Li Muyun said that bringing her to buy things was just a joke, and she felt a little disappointed. After all, Li Muyun had been picking what he needed after entering the store and never mentioned the gift again.

"What? Do you think your young master has forgotten this matter?" Li Muyun had a bad smile on his face. It was obvious that all the behavior just now was intentional, and the purpose was to see the little girl's depressed appearance.

But Li Muyun obviously underestimated the little girl. After hearing that she was stunned for a short time, the little girl pulled his sleeve and said, "Young master, why don't you forget it. I've spent so much money just now, so I won't want my gift!"

"You must give the reward you should give. Choose one you like later..."

...

By the time Li Muyun and the little girl Mu Yu came out of the jewelry store, it was already evening and the two of them had no interest in continuing to go shopping, so they decided to go home. After only three days, the old man in the store sent crystal sunglasses to the house.

During these three days, Li Muyun was not idle. While arranging the fat man to measure the walls of various government officials, he also began to receive copper coins sent by each company.

Since he was cheated by Li Shimin last time, he has made a decision to keep his money anyway and never let an anxious emperor take advantage of it.

The facts proved that His Majesty Li Er had indeed tasted the sweetness. After the 1,400 guan of money was put into the treasury a few days ago, His Majesty the Emperor could not wait to recover his second fund.

Just when he was about to send someone to Li Muyun's mansion, someone came to report to the door: "Your Majesty, Xiaoyao Hou is asking for a visit!"

"Oh? I was thinking about him just now, but he came!" Li Shimin seemed to think this matter was quite interesting and said with interest: "Then let him come in and see what tricks this kid wants to play."

"No" The eunuch who came to inform the news agreed, ran to the outside of the study and shouted at the top of his voice: "Your Majesty has an order, wait for the audience!"

Meeting? It’s not a court meeting, but a fart to meet! Li Muyun rolled his eyes silently, but said nothing. He followed the eunuch and walked into the imperial study room where he had been to many times. Then he heard a surprised voice from a certain emperor: “Hey, Li Muyun, what is the thing on your face?”
