After the prosperous Tang Dynasty

After hurriedly returning to his yard with Axiu, Xiao Yansui stood directly in front of the desk with a test tube in his hand.

She fiddled with the test tube for a while, and couldn't help but took the cup on the table next to her, poured a tube of tea into it, and watched the slightly brown liquid flow in the almost transparent test tube , Xiao Yansui finally nodded in satisfaction, and gave a high evaluation: "The effect is very good."

Xiao Yansui fiddled with the other experimental equipment one by one before giving up.

However, before Axiu could breathe a sigh of relief, Xiao Yansui had already ordered as a matter of course: "Give me a few more test tubes, and other equipment, large and small, as well."

Axiu couldn't help being stunned for a moment, and then quickly nodded her head in response, "My servant has made a note."

After instructing Axiu to need more experimental equipment, Xiao Yansui, who was still in high spirits, rolled up her sleeves and planned to do some random experiments to find the feel.

Although he often did experiments before, Xiao Yansui was almost numb to this rough operation mode of "physical chemistry in life". Sui wished he could get his hands on all the experimental equipment he just got.

It's a pity that the sky didn't fulfill people's wishes, Xiao Yansui leisurely hadn't set up the experimental equipment yet, Axiu, who had just left, came back in a hurry, and said quickly: "Liu Niang, the one in the main courtyard Send someone over here, please go over."

"Well, Ah Weng is looking for me?" Xiao Yansui put down the things in his hands for the time being, raised his eyebrows slightly, turned around, and walked out of the yard while lowering his head and putting down the sleeves he had just rolled up again.

It is true that the clothes made of extremely soft silk fabric are soft and light, but it is also true that every piece of fabric is easy to wrinkle when folded, let alone Xiao Yansui rolled up his sleeves so casually.

After putting down the sleeves, looking at the slightly wrinkled sleeves like crepe paper, Xiao Yansui pursed the corners of her mouth a little dumbfounded. On the way to Xiao Song's main courtyard, she kept tugging at the fabric of the cuffs, Make it appear as smooth as possible.

"What is Ah Weng looking for me for?" Xiao Yansui never stopped moving his hands along the way, but Xiao Yansui still asked casually about the maid in the main courtyard who came to look for her.

The servant girl replied softly: "The messenger from Chang'an City's family has come, that's why the gentleman invited Liu Niang over."

After hearing this, Xiao Yansui couldn't help showing a little smile, "Ah, it's a coincidence that I came here. I've been thinking about writing a letter to Aniang and the others for the past two days! We happened to reply together."

The maid also laughed and said: "The family must be thinking about Liu Niang."

While talking, Xiao Yansui had already arrived at the main courtyard, and Xiao Yansui walked in, but before anyone arrived, he shouted briskly to the voice inside: "Ah Weng, I'm coming!"

Inside the room, the smiling Xiao Song's voice came out immediately, "Liu Niang is here!"

Xiao Yansui walked in, and saw two letters on the table next to grandfather Xiao Song, one had been opened, and the other was still sealed.

Xiao Song pointed to the letter that had been opened, smiled and said to Xiao Yansui: "Come help Ah Weng read the letter."

"Okay." Xiao Yansui readily agreed, and after sitting next to Xiao Song, he picked up both letters, only to find that one was a letter from home, and the other was actually Xiao Wu trying to stuff it in. The "secret letter" to her.

For this kind of tricks played between his grandson and granddaughter, Xiao Song saw everything in his eyes, watched them quarrel happily all day long, but never said anything.

After Xiao Yansui looked at Xiao Wu's "secret letter" and put it down again, Xiao Song smiled and shook his head, and said casually: "People's eyes are not so good when they get older! You can still see it before, but recently It feels like everything is blurry.”

Xiao Yansui was taken aback for a moment, then subconsciously raised her head to look into Xiao Song's eyes.

Because of old age, Xiao Song's eyes are already covered with wrinkles.The snow-white beard is neatly combed, which can be regarded as a "beautiful beard", and the same gray hair is also combed with a light but fine wooden crown, which looks quite dignified and elegant.

Even though he is living a healthy and well-maintained life, Xiao Song's face still has some spots formed by slight pigmentation, which are the irreversible traces left by the long and compassionate years.

There was never a moment when Xiao Yansui clearly realized that his grandfather Xiao Song was old.

Moreover, in the feudal era of the Tang Dynasty, when the average age of people may not exceed 30 years old, Xiao Song, who has been pampered all his life, can definitely be called a longevity at his current age.

Some strange feelings suddenly flashed in his heart, Xiao Yansui pursed his lips, lowered his eyes slightly, and quickly suppressed all those complicated and inexplicable emotions.

Due to Xiao Yansui's personality, even if she comforts and makes people happy, she can't say that Xiao Song is not old, you will live a long life, after her lips trembled slightly, she just opened her mouth and said in a firm tone : "Don't worry, Ah Weng, I'll have someone sharpen a pair of lenses for you later, and you can see clearly after wearing them."

Xiao Song: "...?" Huh?

Xiao Yansui's tense face finally showed a slight smile, she pointed to her eyes, and said to Xiao Song confidently: "You only need a few simple tools, you can do it, Aunt." I can see the handwriting."

"Oh..." Xiao Song suddenly understood, but he didn't doubt the authenticity of his granddaughter's words.

After all, Xiao Yansui did what she said, and she was actually quite reliable in what she did, but the things she did may not be fully acceptable and adaptable in the eyes of others.

At the same time, Xiao Song couldn't help showing a curious look on his face, "What gadget are you talking about?"

Xiao Yansui directly drew the appearance of a pair of glasses with his hand, and briefly described: "That is, two magnifying glasses are connected to the frame, and the frame also has two handles, which can be hung behind the ears and fixed on the bridge of the nose. position, through the magnifying glass, Aon, you can see the handwriting clearly."

"Is there another way?" Xiao Song was eager to try.

After all, after getting old, the eyes gradually become less clear, and the vision becomes blurred, and no one is used to it.

Moreover, presbyopia caused by the decline in body quality after people get old is actually not just the inability to see things nearby.

"Well, Ah Weng, I'll finish reading the letter, and I'll get it later." Xiao Yansui said confidently, and it was a coincidence that the glass in the workshop is all ready-made, and so many test tubes and measuring cups were fired for her. After bottoming the flask, I think those craftsmen also have some experience in blowing glass products. In this case, it should not be very difficult for them to make some convex lenses with different thicknesses.

——After all, Xiao Yansui knows the principle of reading glasses, and also knows how to calculate the prescription required for reading glasses. However, she does not have the tools to test grandfather Xiao Song at all, and it is not easy to accurately measure the craftsmen. The power of the hand-polished lenses, so in the end, Xiao Song still needs to bring his own real feelings...

In addition, there is another problem that, whether it is Xiao Yansui's own experimental equipment or the glass on the windows of the house, Xiao Yansui does not require absolute transparency. After all, as long as the glass is generally clear enough, it is already possible to see. It is very clear and will not affect the lighting.However, when it comes to making lenses, it is absolutely not acceptable if the transparency of the glass is low.

Fortunately, the required quantity of convex lens lenses for Xiao Song is very small. Xiao Yansui doesn't mind at all that Anxi's craftsmen have a lot of materials, and finally make a limited number of lenses, even if it is really luck, as long as they can finally She has no problem with qualified finished products.

Xiao Yansui was thinking about things in her mind, but after picking up the opened envelope, she quickly focused on the things written in the letter.

"Aniang asked, what about my Jiji ceremony...?" In the middle of reading the letter, Xiao Yansui blinked twice, and looked at Xiao Song quite innocently.

"Ah Weng's plan is to wait until you are 20 years old." Xiao Song briefly stated his plan, together with Zhou Shi's ancient etiquette, after all, relatively speaking, powerful families pay more attention to this.

Xiao Yansui was noncommittal, anyway, she didn't understand these customs. However, the Jiji ceremony in the Tang Dynasty is actually the same as the coming-of-age ceremony in later generations. If the family has money and time to pay attention to this, it will naturally invite a lot of guests But it's very lively, sooner or later it's a circle of tossing.If you live a more casual life, your birthday is a family meal together, so you don't have to pay so much attention...

"Okay." Now that Ji Jili's problem was solved, Xiao Yansui naturally agreed directly without any hesitation, and then continued to read the letter.

"The sage and his concubine went to Huaqing Palace to play...the crown prince of the East Palace accepted Zhang Liangdi, and a gift was prepared at home..." Xiao Yansui thought about what happened in Chang'an City recently, and concluded: "Chang'an City has been lively recently."

After a pause, Xiao Yansui took the initiative to ask: "Aunt, the family and the Crown Prince's East Palace were not always close... Why did you specifically mention the gift in the letter this time?"

Xiao Song pointed to himself, and said with a smile: "Although Ah Weng is not in Chang'an City, he is still the prince and grand master, and the East Palace accepts a new concubine, this standard is second only to the grand marriage with the prince's concubine. Naturally, it is necessary to prepare a gift."

Usually alienation returns to alienation, but we must not lose etiquette.

What's more, Xiao Song, the current old head of the Xiao family in Lanling, has retired for retirement, and is far away from the turbulent Chang'an city. After all, Xiao Song, who has the greatest influence, has withdrawn from the arena of fighting for power and profit. For now, it can be said that he is harmless to everyone...

After reading the letter, Xiao Yansui stuffed the other letter that Xiao Wu gave to her alone into her pocket as if nothing had happened, then got up and said, "Ah, I'll get you lenses!"
