All the members are in love with the group, and the cub is causing trouble in the Tang Dynasty.

On the early morning of the fourth day of March, Yuan Yuansheng was sent to Hongwen Hall by Uncle He Fan helplessly.

He Fan was puzzled: "If you don't want to go to school, just rest."

Yuan Yuan hugged his neck and sighed slightly: "I still have big things to do!"

He Fan patted her head: "Okay, let's go in."

Yuan Yuan hugged his neck again and moaned without letting go.

Suddenly, the fragrance of milk tea wafted into Hongwen Hall.

Yuan Yuan sniffed and quickly patted He Fan on the shoulder.

He Fan put her down, and the little kid ran inside without looking back.

"Brother Qingque, brother Qingque! Yuanyuan wants to drink milk tea too!!!"

He Fan: "..."

It's really no surprise.

It just so happened that the papermaking workshop of Hongwenguan produced finished products today. After a law class, the owner of the workshop, Yuan Yuan, went over to inspect it with little hands on his back.

The papermaking workshop produced bamboo paper, as well as large-format paper for calligraphy and painting.

The craftsmen of this era are very capable, but what they lack is a broad mind.

Many operating methods that may seem superficial to later generations could not be imagined by them due to the limitations of the thinking and vision of the times.

Yuan Yuan touched the paper with her little hands and nodded seriously.

"Then let's make parchment together quickly!!!"

She counted on her fingers: "Pulp tree bark, hibiscus bark, mulberry bark..."

"Ingredients...seven-tenths tree bark plus bamboo and hemp, and three-tenths dry straw."

After she finished speaking, the craftsman couldn't make up his mind for a moment and looked at His Royal Highness behind him.

Li Chengqian smiled and nodded.

The craftsman went to work again.

The made bamboo paper has been sent to Liangyi Hall, and Li Shimin, Fang Xuanling and others are watching it carefully.

Fang Xuanling sighed: "This bamboo paper is so... white, soft, delicate and smooth..."

Li Shimin took a piece of paper, picked up the pen and wrote a few words. After putting down the pen, he stroked his beard and said: "Wet it to preserve the ink, it's good paper."

Bamboo paper has been tried for a long time, but it has never been popularized because it is not as low-cost and tough as existing paper such as hemp paper.

But the newly made paper is more suitable for writing and recording.

Du Ruhui raised the paper with writing on it to his eyes: "It is indeed extraordinary. I heard that it is mixed with a variety of raw materials and the cost is not high."

"There are many bamboos in the south of the Yangtze River, so we can vigorously promote bamboo paper."

Zhang Ananda and another chamberlain unfolded the large-format paper, and everyone gathered around to look at it.

Wei Zheng, who has always been calm, couldn't help but exclaim: "Wonderful!"

"Even a beautiful picture of mountains and rivers can be painted."

Several people were excited by each other's words. Yuchi Jingde sat calmly and drank tea.

"My Erlang has been pounding bamboo and hemp for many days, and his efforts have been in vain."

Li Shimin turned his head to look at him and asked Zhang Anan: "Have I summoned him?"

Zhang Ananda was a bit speechless: "When Wu Guogong saw me coming with papers, he followed him."

He glanced at Li Shimin's expression. When Wu Guogong entered the palace just now, His Majesty didn't say much when he saw him.

Why did I get bored of it all of a sudden?

Yuchi Jingde had a stern look on his face: "My second son was involved in the work. The idea came from my sworn brother. Can't I follow him and have a look?"

Li Shimin smiled faintly: "Would you like to give up my Liangyi Palace to you to discuss politics? Is it okay for you to sit on my throne?"

Yuchi Jingde quickly got up and knelt down: "I don't dare."

Li Shimin hummed and turned to look at the new paper.

Yuchi Jingde stretched his neck and looked at it for a while. Seeing that several civil servants couldn't put it down, he started to murmur again: "Where are you going? I've asked before. They still want to make many kinds of paper together."

"There are many books that can be used for a long time but the ink is not stained, the writing is easy to dry, the ink does not fade, and the ink is not corroded for a long time."

"My son said that products vary from place to place. The more types of raw materials they try out, the more ways people in different places can make money."

Seeing that everyone's attention was attracted to him, he simply stopped kneeling, stood up and walked over: "They also want to make vellum paper, straw paper, hard paper, and soft paper."

Several other civil servants were all old foxes. They didn't show it on their faces, but they were shocked in their hearts.

I was also a little envious of Yuchi Jingde, an old man. Both father and son played well with the little princess, and they had all the first-hand information.

Fang and Du both wanted to know why such a young child had so many fantastic ideas.

But thinking about the young lady's arithmetic ability, she suppressed her doubts.

There are all kinds of strange things in the world, but they are not bad things after all.

In the afternoon, the princes, princes, and children of high-ranking officials who participated in papermaking all received awards.

Even Princess Changle and Yuan Qing, who gave milk tea and fried chicken to the young men from time to time, received rewards.

The servants in the palace carried out His Majesty's oral instructions from house to house with great fanfare, giving each family a lot of face.

The whole city is envious.

***

Yuan Yuan took temporary guardian Zhao Wang to find Li Chunfeng in the afternoon.

She knew that Li Chunfeng was writing a book, so she went to find him with new paper.

When they arrived at the Taishi Bureau, Li Chunfeng was looking at the graffiti left by Yuan Yuan when he worked here last time.

Yuan Yuan saw it from afar and ran over quickly: "Ah ah ah ah, don't move!!!"

Li Chunfeng's hand shook, and the paper with many ink marks fell to the ground.

Yuan Yuan quickly picked it up, pouted and blew on it.

Li Chunfeng disagreed: "It's not a secret, nothing important."

Yuan Yuan glared at him angrily: "It's so important!!!"

Li Chunfeng's mouth twitched: "Okay, is this bamboo you drew? Crab???"

Yuan Yuan snorted: "No, this is something very important!!!"

Li Chunfeng looked at King Zhao: "Then, can your Majesty see what it is?"

The little boy looked at King Zhao expectantly.

King Zhao looked at the ink dots on the "painting" and the ink marks scratched here and there, and fell into deep thought.

Yuan Yuan waited for a while but got no answer, and pouted angrily.

King Zhao coughed and said, "I have little talent and little knowledge, why don't you explain it to me?"

The little fat boy snorted again: "It's a telescope!!!"

Li Chunfeng raised his eyebrows: "What is this telescope?"

King Zhao also looked puzzled.

Yuan Yuan felt a little guilty, having only listened to half of the class.

"Telescopes are fun. You can see far, far away places."

Although telescopes have been eliminated in the interstellar world, people from Ancient Blue Star like them.

The little kid scratched his chin: "Then I'll tell you tomorrow."

Li Chunfeng swallowed and wanted to scream like a prairie dog, but he didn't believe that such a young child could make anything that could see far and far away.

King Zhao was also very shocked. He knew that this child was precocious.

If you can see the situation in the distance, it will be very helpful when marching and fighting.

But when I touched the graffiti with my peripheral vision, I really couldn't think of anything sophisticated.

He calmly put the bamboo paper in his hand on the table and said to Li Chunfeng: "The new paper made by Hongwen Hall is specially used for Dr. Li's daily writing."

"This new paper dries easily when writing, and the ink will not fade for a long time. It is very suitable for writing books."

Li Chunfeng's attention shifted to the paper and he couldn't help but reach out and touch it. It was indeed different from the paper he usually used.

He lowered his eyes at the chubby little lady and touched her head: "Okay, thank you for your concern, my little colleague."

Yuan Yuan nodded: "Yes, yes, yes, I will miss you!!!"
