After reading the prescriptions, Su Luo gave Du Siyuan two more prescriptions: one for children's cold medicine and one for children's fever reducer, both containing a lot of honey and sucrose.

Du Siyuan received the prescription, looked at it for a while, and then laughed: "Grandmaster, are you sure we're making medicine and not candy?"

You're questioning me?

"Siyuan wouldn't dare, but Grandmaster, do these two medicines also need instructions?"

"Of course, this is children's medicine, and the dosage should be adjusted according to age. The instructions have more words than necessary."

"But!"

"Don't worry, I have a way to solve this. Once I succeed, I'll resolve it immediately. You can keep an eye on it for the next few days."

"good!"

Du Siyuan was at his wit's end when it came to this matter, and could only wait and see what other solutions Su Luo could come up with.

Back at the Du residence, Su Luo asked Yun Niangzi to prepare ink and wooden boards for her, and she made all sorts of small knives in the backyard.

"Miss Su, do you want some words engraved? If so, this kind of engraving knife won't do; it's too big."

Su Luo turned to look at Yun Hui: "Does Madam Yun also know how to carve?"

Yun Hui sat opposite Su Luo with a smile, looking at the things on the table and recalling them.

"Before I got married, I often played with these things to pass the time, but most of a woman's things are not presentable."

Later, she followed her husband wherever he went, and even learned to identify medicinal herbs from Old Du. As a result, her carving skills were practically abandoned.

Yunhui was quite satisfied with her life. She had a son, and her husband never took a concubine. The two of them lived their lives together like this.

Except for those three years when they had to obey the emperor's orders, the couple never separated.

Upon hearing that Yun Hui could carve characters, Su Luo was overjoyed. She had studied it for a long time but still found it difficult to carve any characters.

"Miss Yun, if you know how, could you carve ten characters for me? It doesn't matter if they're good or bad. I want to try making something."

Su Luo handed everything over to Yun Hui at once. The wood particles were square, about the size of a finger.

Su Luo made a plate out of a wooden board. By the time she finished, Yun Hui had also carved more than ten characters.

She carved these words as she came up with them, without knowing what Su Luo intended to use them for.

Su Luo made the wooden board into small grids, then placed the characters carved by Yun Hui on them, applied ink with a brush, and laid a piece of paper flat.

With a gentle press, the words on the stencil can be transferred onto the paper.

Yunhui had never seen anyone do this before; her not-so-good-looking handwriting could actually be printed on paper like this.

"Madam Su, after a whole day of work, what's the point of all this?"

It was already dark when Du Xiuyuan returned from the palace, and Du Siyuan also arrived home. Upon their return, they saw a table full of knives in front of them.

"Yes, it is very useful."

"Madam Su, what are you doing here?"

Du Xiuyuan was still holding his imperial physician's hat in one hand. When he saw the wood chips on the ground, he thought that Yun Hui had suddenly decided to play with wood carving again because she was thinking about things before she got married.

"I'm carving words for Madam Su, but I don't know what Madam Su is going to do."

When Su Luo saw that Du Siyuan had also returned, she quickly called out to him, "Siyuan, come here for a moment."

Du Siyuan looked a little tired. After sending Su Luo back, he went to write instructions for the medicine. After a few days, his wrist was still sore.

"Grandmaster, Father, Mother!" Du Siyuan bowed to his elders before standing properly.

"Siyuan, look, I've successfully made this. With this live printing, there's no need to write the instructions for medicines. You can just make a rubbing and print the text."

The phrase "No need to write instructions anymore" jolted Du Siyuan awake, instantly energizing him.

"Grandmaster, you said that if we use this, we don't need to write an instruction manual. So how do we make this? Can you try it on for me?"

Su Luo repeated the process for Du Siyuan, showing how a single sheet of paper could print the characters on the stencil instantly.

"Grandmaster, do you want to carve all the words in the instruction manual onto this wooden board, then ink it, and then print the words out?"

"That's right, just as you understand it. And this is movable type, which can be changed at will, making it perfect for printing our instruction manuals."

The idea was good, but Du Siyuan still wasn't happy.

"Has the Grandmaster found someone to carve the inscription?"

There isn't a Su Luo available yet, but in such a large city as the capital, finding a few people who can engrave characters shouldn't be difficult.

"Is it impossible?"

Su Luo glanced at Du Siyuan and Du Xiuyuan, both of whom remained silent.

After listening for a long time, Yun Hui finally realized that Su Luo did this to print the instructions for the medicine.

He held Su Luo's hand and comforted her, "Miss Su, you don't know this, there are many craftsmen who can carve, but the font on the instruction manual is too small. I heard from Siyuan that they all use feathers to write on it."

It's said that this is barely enough to fit all these characters. If you were to have someone carve the lettering, the characters would have to be incredibly small.

Some characters have many strokes, unlike the simple ones I carved. As far as I know, there might only be one person in the entire Nanning who can carve such small characters.

If someone can carve it, things will be much easier: "We can offer more silver, one hundred taels for a complete set of books, or perhaps even more."

If it were just writing, a teacher could earn five taels a month. If he used that money to hire someone to engrave the characters, Ji'an Hall could earn back the money for its medicines in just one month.

Once the medicine has instructions, we can sell more, and we can achieve that in half a month.

At that time, only one literate worker will be needed to replace this position, killing two birds with one stone.

“Madam Su, this is probably not something that can be accomplished with money,” Du Xiuyuan said.

Su Luo: "..."

"Grandmaster, this person is the Minister of the Imperial Secretariat of this dynasty, Master Nie. He is over fifty-seven years old this year and has devoted his life to books. He detests the airs of merchants the most."

If he knew we were using the characters he carved for business, he might come after us with a knife and block our doorstep.

This sounds like a stubborn old man, and such a person is difficult to deal with.

"Besides him, is there really no one else in the capital who can carve such small characters?"

Du Xiuyuan said, "I haven't heard of any others."

It seems Su Luo really needs to find an opportunity to meet this Minister of the Imperial Secretariat. If she wants to see him, she'll have to wait until the 26th.

"Doctor Du, if I were to exchange this movable type printing technology with Lord Nie, would it be possible to obtain a complete engraving of the book?"

Su Luo had a general understanding of the position of Shangshu Ling, who was in charge of managing palace books, copying books, and making books. Naturally, he needed this living printing technique even more than Su Luo.

“This is worth a try. I saw your design, Su Niangzi, and it represents a significant breakthrough in terms of text.”
