After reading the heart milk ball, the cannon fodder family went crazy

study.

Su Dahe approved Su Shaoan and the others to have a holiday, and they suddenly ran away without a trace like wild horses.

Su Zhaozhao wanted to go back to the house and go to sleep, but as soon as he stepped out, Su Dahe hugged him and put him on his lap.

"Master Zheng, Zhao Zhao is still young. I don't trust her to go back alone. Do you mind?"

Su Zhaozhao's face was full of accusations. How could she be younger?

Although she is still a bean sprout, her IQ is that of a college student, only clear, not stupid!
"If Mu Qian doesn't tell me, I won't worry about Zhao Zhao going back alone, so just let her stay here." Zheng Wenchang said with a smile.

Su Dahe breathed a sigh of relief and asked, "I wonder why you are here?"

Based on Su Dahe's understanding of Zheng Wenchang, he came to the Three Treasures Hall for no reason, so he must have something to do when he came here today.

Just in case, he left the humanoid plug-in Su Zhaozhao behind.

"I'm here to tell you that the Enlightenment Book has been compiled and approved by His Majesty, and it will be released in a few days."

Zheng Wenchang was filled with emotion in his heart. He thought that this matter would be blocked by the aristocratic family, but he did not expect that it went surprisingly smoothly. He guessed that the article "The Friendship between Cui and Lu" played a role.

As the heads of the aristocratic family, the Cui Lu family all agreed to publish and sell the book, so the others naturally had nothing to say.

Zheng Wenchang took out a book and handed it to Su Dahe, and explained: "Mu Qian, this is the first book of "Celebrity Stories". You are the author of this book, and this book should be yours."

Su Dahe took the book and looked through it. The first story in the book was "The Friendship of Cui and Lu". The content was basically written by him, with just a few more words to praise Master Cui and Master Lu.

In addition, there are a few more stories about ordinary people in Chu State in the book, and the rest are stories about famous people in ancient times.

Su Zhaozhao sat on Su Dahe's lap and read the contents of the book.

She expected to see classical Chinese writing, but she didn't expect that Su Dahe wrote it in vernacular and even had punctuation marks!

Su Zhaozhao was confused.

Su Dahe is such a fucking genius, he actually created vernacular literature without any teacher!
Moreover, the usage of the land inside made her feel ashamed even after looking at it.

Su Dahe: Low-key and low-key, I just stand on the shoulders of giants (Su Zhaozhao).

"Sir, I wonder how much this book costs?" Su Dahe asked after closing the book.

"This book is an enlightenment book. It's not expensive, only five hundred coins a copy." Zheng Wenchang explained.

Su Zhaozhao calculated in his mind that ordinary people worked hard and could save up to two or three taels of silver a year, and this book accounted for one-sixth of it. The price was not expensive, it was simply expensive.

But when he thought about the efficiency of printing in ancient times, Su Zhaozhao understood instantly.

Chu State had movable type printing and block printing. Movable type printing was highly efficient, but it was troublesome to use, so block printing was generally used.

But despite this, very few books are printed every year, and they are so expensive that ordinary people simply cannot afford them.

Therefore, the government carved the contents of the book into stone tablets and provided people with free rubbings.

Sure enough, Zheng Wenchang said this in his next sentence.

"The craftsmen are arranging and carving them into stone tablets. They will be placed in the Royal Bookstore and people can make rubbings for free."

"This method is very good." Su Dahe's eyes lit up and he said sincerely.

The next second, he sighed and said: "It's a pity that except for the capital, rubbings cannot be made anywhere else."

Even if the famous works of today's great Confucians are to be spread throughout the country, it will take more than half a year, let alone a new book like "Celebrity Stories".

I'm afraid it will take several years for readers across the country to see this book.

[Hey, to put it bluntly, printing efficiency is still too low. If there is a printing press, printing tens of thousands of books a day is not a problem]

[I remember the history teacher said that the spread of ancient knowledge was slow, in fact, a big reason was that printing efficiency could not keep up.] Hearing this, Su Dahe and Zheng Wenchang wanted to applaud the history teacher Su Zhaozhao said.

Fortunately for Zheng Wenchang, the Zheng family came from an official family and had no shortage of books since he was a child.

However, many of the original copies handed down from ancient times are in the hands of aristocratic families. Not to mention some of the original copies, Zheng Wenchang has only heard of their names.

As for Su Dahe, it was even worse. He had been studying for many years and had never bought a single book.

His books were either borrowed from classmates and copied, or they were rubbed on stone tablets. This "Celebrity Stories" was the first book he received in his life.

But here comes the question, what is a printing press?
[With current technology, it is probably impossible to build a printing press, but lithography should be possible]

Su Dahe and Zheng Wenchang's eyes lit up. This lithography technique sounded very powerful upon hearing it.

But unfortunately, from Su Zhaozhao's inner voice, the two of them did not hear how to make this thing.

But as smart as Su Dahe, he immediately thought of someone.

After chatting for a while, Zheng Wenchang left.

Seeing that Su Shaoping was off duty, Su Dahe asked his servants to wait at the gate, and asked him to come to the study as soon as Su Shaoping came back.

About half an hour later, Su Shaoping came.

Su Dahe didn't beat around the bush and went straight to the point: "Shaoping, do you have any way to improve printing technology?"

This question made Su Shaoping confused. He said bluntly: "I haven't tried it."

"Shaoping, can you give it a try? The current printing efficiency is too low. I want a simpler and faster way to print books." Su Dahe said.

"I can try." Su Shaoping said without hesitation.

Su Dahe rarely asked him to do things, so there must be a reason for him to do so now.

Su Zhaozhao was sitting aside eating snacks. After hearing this, he couldn't help but think of the popular science about the development of printing that he saw at station B.

What are letterpress printing, lithographic printing, gravure printing, orifice printing, soft plate printing, lead movable type printing...

The advantages and disadvantages were explained clearly and the two people were dumbfounded by the professional terms.

The lithographic printing technique that Su Zhaozhao mentioned before is a type of lithographic printing.

Combining the advantages and disadvantages of other printing techniques, Su Shaoping believes that lithographic printing is more suitable for the present.

Apart from the high initial investment and the need for specially made ink, lithography has no disadvantages.

Thinking of this, Su Shaoping said to Su Dahe: "Third uncle, give me a month and I will definitely improve my printing skills."

"Then I'll leave it to you. If you have any questions, you can always tell me."

Su Dahe wanted to tell Su Shaoping directly how to make lithography, but he swallowed the words again.

It would be embarrassing if Su Shaoping asked him how he knew.

Since Su Shaoping became an official, his mind has become much more flexible, and ordinary excuses really can't fool him.

So he planned to wait until Su Shaoping reached a bottleneck before giving him a subtle reminder.

"Shaoping, how is your engine research going?" Su Dahe suddenly asked.

Hearing this, Su Shaoping became excited instantly.

"I figured it out!"

Su Zhaozhao, who was eating snacks, was stunned, and the sweet-scented osmanthus cake in his hand rolled to the ground.
