After the prosperous Tang Dynasty

Xiao Song looked at the letter left on the table, and then looked up at his granddaughter's calm look when she left Xiao Wu's letter in her pocket, couldn't help but shook her head with a smile.

Although full of curiosity, Xiao Song is happy to see the grandson and granddaughter's brother and sister have deep feelings and they will hide from adults to play these little tricks.

The other half, after Xiao Yansui returned to the yard with Xiao Wu's letter to her, she didn't continue to fiddle with her experimental equipment, but called Axiu directly, and ordered: "Prepare the carriage, I'm going to the workshop Over there."

At that time, people loved riding horses. In the Tang Dynasty, whether it was a young gentleman or a young lady, most of the trips were usually on horseback. Relatively speaking, it was convenient and fast.

Xiao Yansui is not too enthusiastic about horse riding, but she does not reject it either.It's just that although riding a horse is relatively flexible, when Xiao Yansui wants to think about something on the road, he is more inclined to use a horse-drawn carriage. After all, there is a small enclosed space, and he doesn't need to look at the road...

Axiu showed hesitation, but she followed Xiao Yansui's order first, prepared the carriage, and sent someone to notify the workshop, then she asked worriedly, "Why did Liu Niang say so suddenly?" Do you want to go to the workshop? The kiln there is for calcination of cement and glass, so it's really not a good place to go..."

Xiao Yansui was also very close and patient to Axiu, the maid who had been by his side for a long time, and simply replied: "I need a glass craftsman to make some lenses."

Axiu subconsciously wanted to speak, just call the craftsman over and give orders, why Xiao Yansui made this trip in person.However, seeing that Xiao Yansui's face did not show the slightest sign of anxiety, instead he seemed to be pondering all the time, so he quietly closed his mouth again.

Axiu can also vaguely guess that Xiao Yansui must go to the workshop in person, perhaps it may be that the things she wants this time are quite special, and they cannot be copied perfectly by drawing a sketch...

Soon, the carriage of the old house of Xiao Mansion was ready, because it was the carriage that Xiao Yansui often used on weekdays, so the soft cushions inside the carriage were always there, and the teapot was always placed on the small table. put pen and paper...

After Xiao Yansui got into the carriage, he just sat for a while, then directly picked up the pen and paper, and began to simply draw the general shape of the frame and lens of the presbyopic glasses.

Needless to say, the frame must be done by a carpenter.Those craftsmen with many years of experience have really worked hard at their hands.

Before, Xiao Yansui ordered the carpenter to make a two-meter bed with good wood. Her own requirements were very simple, as long as the bed was big enough and comfortable. In fact, she was not too picky about the specific appearance, but those carpenters really worked hard. At that time, the details of the carvings around the bed far exceeded Xiao Yansui's expectations, and these additional auspicious patterns, for those craftsmen, are the norm that must be added as appropriate under normal circumstances.

For a craftsman who can carve so many patterns on the bed board, Xiao Yansui has no doubt that as long as these carpenters are given clear drawings, they can make any frame for her, and it is estimated that the temples of the glasses must be hand-carved... …

On the glass-making side, the glass-blowing craftsmen are mainly good at making utensils such as dishes, bottles, and cups. Simple glass decoration should be good. Things with relatively simple structures such as convex lenses should be fine under normal circumstances. Not too much.

In fact, not to mention these craftsmen from the Tang Dynasty, it is because Xiao Yansui has good eyesight in this life, and she always had myopia glasses at hand in her previous life. When she just tinkered with the glass, she completely forgot that glass can also be used as lenses ...

While drawing pictures, Xiao Yansui slightly pursed the corners of her lips.

Thanks to my grandfather Xiao Song's presbyopia, reading glasses made of convex lenses are simple in principle and relatively easy to make.If it becomes a concave lens required for myopia, the specific refraction angle and lens power, even if the principle of the lens is essentially the same, it will become much more troublesome when you really have to do it manually.

Axiu was so quiet that she sat beside Xiao Yansui without making a sound. She caught a glimpse of the sketch that Xiao Yansui had just drawn in her hand, and couldn't understand it at all, so she stopped thinking about it and lifted the teapot very lightly. When Xiao Yansui poured half a glass of water into the teacup, it was still as if there was no sound.

After a while, still holding the pen in his right hand, Xiao Yansui stretched out his left hand according to Xiao Yansui who was following the notebook, without even looking up, he just groped for the teacup at the most convenient position, picked it up and took a sip water.

Xiaojia Village is only this small, it is the entire Shanhai Town, and it is prosperous, but its area is also limited.

The country road was smooth, and the carriage drove all the way, and it didn't take long for it to stop firmly in the backyard of the workshop.

The kiln here has existed for a long time, but the many craftsmen and manpower around it gradually increased after Xiao Yansui came.

Axiu was the first to jump out of the carriage, and wanted to turn around to help Xiao Yansui, but was in vain.

Xiao Yansui, who still had a homemade charcoal pencil and a notebook in his hand, lifted the curtain of the carriage by himself, and jumped down from the other side steadily.

The accompanying guards and servants all got off their horses one after another, stood aside and waited without saying much.

The steward in the workshop just received the news of someone coming from the mansion, and now he directly greeted him, saying, "Liu Niang."

Xiao Yansui nodded, and took a quick look at the craftsmen here. Some people should still be busy everywhere, but those skilled craftsmen, at least in Xiao Yansui, Axiu or other guard servants around her, have already It's almost familiar.

"Where's the craftsman who helped me blow those glass bottle bottoms these days?" Xiao Yansui stepped forward and asked the manager with a smile, "Call the man over, I want him to help me make something else now." s things."

--After all, in fact, the thickness and shape of the bottom of the flask and beaker is almost the same as that of a convex lens. Xiao Yansui feels that it can be used with a little modification.

The person in charge naturally nodded repeatedly, and immediately called someone over.

The craftsman seemed to never care about his master's family, but he was the only master who spoke and took care of things besides Xiao Song and Mr. Xiao, so he was inevitably a little nervous and cautious.

Xiao Yansui directly put the notebook in his hand in front of him, "I want a convex lens, can you make glass like this!"

Said it was an inquiry, but Xiao Yansui's tone was completely declarative.

When it came to his own craft, the craftsman finally let go a little bit, looked carefully at Xiao Yansui's convex lens on the blueprint for a while, and then briefly described and gestured with uncertainty, and got Xiao Yansui's After Yan Sui's affirmative reply, he finally breathed a sigh of relief, nodded and said, "It can be done!"

"Then let's do it now!" Xiao Yansui didn't see the slightest sign of anxiety on his face, but he was a straightforward man of action.

The glass craftsman also responded simply, turned around and led Xiao Yansui towards the craftsman's platform.

The person in charge was stunned for a moment, still a little unresponsive, "Huh?" After a pause, he quickly chased after him and accompanied him.

On the other hand, Axiu, who had long been accustomed to Xiao Yansui's accident style, followed her early in the morning.

When using boiling water, Xiao Yansui reckoned that Xiao Song's eyesight should not be particularly high, after all, he had never heard him mention the problem of blurred vision before.

But after thinking about it, I felt that, like my grandfather Xiao Song and others who were involved in politics, showing emotions and anger is the most basic basic skill, and the eyes are not very clear. Anyway, when Xiao Song was still in court , since he was young, he has been famous for letting go of things, not to mention that he rarely writes memorials to Xuanzong, and he hardly reviews official documents under his command. His eyes are dazzled, and if he doesn't say it himself, others may not be able to discover this...

Combined with Xiao Song's current age, in fact, he is no longer in his fifties when his eyes just started to blur.

Feeling slightly embarrassed, Xiao Yansui felt more and more thinking about it, maybe his grandfather's presbyopia had lasted for many years, but actually many old people around him were like this, Xiao Song probably wouldn't take it too seriously... …

The corners of Xiao Yansui's mouth twitched, and then looked at the glass craftsman who made the lenses that were obviously thinner according to her requirements at first, and quickly changed his mind: "I'll also make a few more pairs that are thicker in the middle, yes , the one in your hand is almost enough... Well, let’s get some more, you should be more accurate in your hand, and then divide them into two piles according to the thickness and line them up for me later!”

The craftsman was still concentrating on blowing glass to make lenses, and didn't bother to reply immediately. The steward next to him hastily agreed, "Don't worry, Liu Niang."

After a while, after getting all the lenses in hand, Xiao Yansui picked up the lenses and looked at the magnification effect, then nodded slightly.

She came and left just as quickly. With a lot of lenses, she immediately found the carpenter, and said calmly, "Just make a frame for me according to the size of these lenses. First, I need a simpler style, with a support on the bottom, and one that can get stuck on the top!"

Although the carpenter didn't know why, his movements were extremely nimble. He chipped a piece of wood, and soon gave Xiao Yansui a mirror frame similar to those used by optical shops.

Taking these things, Xiao Yansui turned her head and went to the main courtyard of her grandfather Xiao Song, running back and forth until now, the sky in the west has gradually been covered by night, as for the secret letter of Xiao Wu in her pocket However, Xiao Yansui hadn't been able to take the time to take a look.

"Liu Niang?" Xiao Song saw his granddaughter coming over at this point, at first he thought she was here to eat with him, and was about to order the kitchen to add more dishes that his granddaughter liked, when he saw, Xiao Yansui When he came this time, he brought a few people with him, and in the tray covered with soft cloth in his hand, there were all small transparent round glass pieces.

Xiao Song: 0v0?
