After binding the system, I became a national mystery person

Su Jinru dismissed the maid and took out a set of movable type from her own space.

This was left over from the previous world, and it comes in handy now.

Su Jinru then wrote down the detailed steps of movable type printing and papermaking on rice paper.

It was already late and the maid was knocking on the study door.

"Princess, it's time for dinner."

Su Jinru sighed softly, placed the pen in her hand on the inkstone, and glanced at the two drawings.

She stood up and looked at the gradually darkening sky outside, with complex emotions surging in her heart.

"come in."

Then put the things in a box and everything is ready.

These are what I want to give to my royal brother. They are my bargaining chips.

The maid opened the door, holding a food box in her hand and a gentle smile on her face.

"Princess, today the imperial kitchen has specially prepared your favorite jade tofu and osmanthus cake, as well as a few seasonal side dishes. I hope you like them."

Su Jinru smiled slightly and nodded.

"I know, just let it go."

After the maids had placed the dishes one by one, she waved her hand for them to leave, and she slowly sat down and began to enjoy this simple but thoughtful dinner.

During the meal, Su Jinru's thoughts were not completely immersed in the food.

She was thinking about how to make her brother agree to her request with these two things, after all, she was still young.

If my royal brother does not agree to let me leave the palace, then I must strive to maximize my interests.

The next morning, when the first ray of sunlight penetrated the clouds and shone on the glazed tiles of the imperial palace, Su Jinru was already ready.

"Chunqing, you accompany me to the Yangxin Palace to find my brother. Everyone else stay here."

"Yes, Your Highness." Chun Qing took the box that Su Jinru had placed on the table this morning.

Su Jinru was wearing an elegant palace dress, with only a few fresh flowers adorning her hair, and she walked with light steps.

Accompanied by Chunqing, he walked through the winding corridors towards the Hall of Mental Cultivation.

The air was filled with the faint scent of morning dew and flowers, as if even within the palace walls there was a bit more life and vigor.

In front of the Yangxin Palace, the guards saw that it was the princess who arrived and bowed and made way. Su Jinru nodded slightly.

As I stepped into the hall, I saw my royal brother Su Chenxun buried in his desk with a frown on his face, as if he was worried about state affairs.

Su Jinru stepped forward and bowed: "Brother, Jinru has something to give you."

The emperor looked up and saw that it was his most beloved sister, and his fatigue eased a little.

He smiled gently and said, "Jinru is here. Do you have anything to offer to my royal brother?"

Su Jinru smiled slightly and gestured to Chunqing to gently place the box in her hand on the dragon table.

The box is made of sandalwood and is finely carved. It is inlaid with several round pearls, which gleam with a soft luster in the morning light, making it look particularly elegant.

"Royal brother, this is what I found in the ancient books I read."

Su Jinru opened the box and took out movable type and two pieces of paper, on which were recorded the specific steps of movable type printing and papermaking.

Su Jinru handed the movable type to her brother.

Su Chenxun took the movable type, and a hint of surprise flashed in his eyes.

He gently stroked the delicate movable type, "Jinru, this thing?"

Su Jinru arranged the movable type, applied ink, and then pressed it on the paper. With a light pressure, the words appeared clearly on the paper.

The ink has just dried, and there is a faint scent of ink.

“This is the secret of movable type printing that I discovered by chance from an ancient book.

It not only greatly improves the efficiency of book printing, but also reduces errors, making the dissemination of knowledge faster and more extensive."

"Brother, I found this in a book. It mentions a craftsman named Bi Sheng, who was the inventor of movable type printing.

However, due to various reasons, this technology was not widely used at the time and only gradually spread later.

Now, I present this to my royal brother, so that more knowledge and wisdom can be passed down to the world."

Upon hearing this, Su Chenxun felt an indescribable excitement in his heart.

As the emperor, he understood even more clearly how important the dissemination of knowledge was in this age of information blockade.

The emergence of movable type printing will undoubtedly be a revolution that will greatly promote the prosperity and development of culture.

"Jinru, your actions will benefit future generations."

Su Chenxun's voice trembled a little. He knew very well that the value of this technology could not be measured by gold, silver or treasures.

He looked up at Su Jinru, his eyes full of admiration and satisfaction.

"My sister has grown up and knows how to share the burdens of my brother. From now on, scholars all over the world will remember your contribution."

Su Jinru smiled slightly and lowered her head humbly.

"Your Majesty, you are joking. Jinru simply stumbled upon this opportunity. It is my honor to be able to share your worries and bring benefits to the people of the world."

Su Chenxun patted Su Jinru's shoulder gently.

Su Chenxun picked up another piece of paper, on which were written the steps of papermaking.

It is a new method that is cheaper than the paper used now, uses simpler materials, and is more efficient to produce.

This not only means that the printing cost of books will be greatly reduced, but also that the dissemination of knowledge will no longer be constrained by the high price of paper.

It also indicates that the popularization of culture and education will enter a new era.

"Jinru, if this method can be successfully implemented, you will be a hero for all eternity."

Su Chenxun's voice was filled with excitement and anticipation.

He knew very well that in this era, the power of knowledge was infinite, and paper, as an important carrier of knowledge dissemination, would have a profound impact on society through its transformation.

Su Chenxun put down the things in his hands, smiled and said to Su Jinru: "Today you are presenting these two things to my brother, is there anything you want?"

"Brother, I want to leave the palace. When my father was alive, he built a princess's mansion for me. Now I want to leave the palace and go to my princess's mansion."

Su Jinru quickly told her purpose, taking advantage of her brother's happiness.

"But you are still young, and it might be inappropriate for you to leave the palace. Although life in the palace is somewhat restrained, it also provides a lot of protection and teachings, which will be of great benefit to your growth."

Su Chenxun's tone revealed a hint of worry. It was not that he was unwilling to fulfill his sister's wish, but as an older brother, he had to consider it carefully.

When Su Jinru heard this, a hint of loss flashed in her eyes, but she quickly adjusted her mood.

She said firmly, "Brother, I know you are worried about me, but I am no longer the little girl who needs to rely on my father, the emperor, and my mother for everything.

I have my own ideas and pursuits, and I hope to study and live in the princess's mansion in my own way.

To get in touch with more people and things, to gain more knowledge, so that I can better assist my brother the Emperor in the future and contribute to the prosperity of the country."

When Su Chenxun heard this, a warm feeling surged in his heart.

He looked at his sister and knew that Su Jinru had made up her mind. Even if he didn't agree now, she would find a way to get out later.

Although my sister has always been well-behaved, the children in the Tian family are very precocious. When I was my sister's age,
