“…… When is this the ghost reason? Empress Eldest Sun's face turned black directly. Gritting silver teeth, some gnashing teeth are authentic.

"The wealth that your father gave to that kid, I'm afraid it should be two or three thousand......

Li Ke hurriedly explained.

"Queen Mother, a few days ago, Cheng Chubi just spent 5,000 yuan to buy a printing shop."

The corners of the eldest grandson's eyes stood up.

"Five thousand, how can it cost so much...... With so much money, he Cheng Saburo built more than enough two printing houses. ”

When Empress Changsun said this, her deep eyes fell on Li Ke's body.

"San Lang, although Cheng Chubi is brilliant, with his temperament, it is impossible to buy any printing workshop and develop new paper."

"Could it be that what makes him have to do this?"

Seeing the queen mother's gaze that seemed to be able to perceive people's hearts, Li Ke could only stiffen his head and salute to the eldest grandson queen.

"Erchen knows that he can't hide it from his mother, there is one thing, Erchen ...... I want to ask the queen mother to hide a thing or two for my son, and hide a thing or two for my eldest brother. ”

Empress Eldest Sun slowly straightened her spine, her eyebrows furrowed slightly, and she waited for Li Ke to speak.

Li Ke's heart was horizontal, so he put his brother in Lishan Tangquan Palace, and after watching himself and his eldest brother paint that day, he stamped his seal and gained inspiration.

I thought of a more novel, and certainly more inexpensive, printing technique, and after that.

"From the beginning, the eldest brother wanted to directly present the printing technology to his father. but was stopped by Brother Bi ......"

Empress Changsun looked at Li Kekan in front of her with a calm face, and carefully described Cheng Sanlang's development of movable type printing.

I felt that I should first test the efficiency and cost of this technique, and if it was feasible, then use this technique to print a large number of books first.

When His Royal Highness the Crown Prince's leg injury healed and returned to Chang'an, His Royal Highness the Crown Prince personally presented to the court and His Majesty......

Li Ke has already finished telling the reason why Cheng Chubi quietly acquired the printing workshop and the reason for developing a new type of paper pattern.

I saw the eldest grandson queen sitting in place stunned, without saying a word, but he didn't dare to disturb, so he could only sit honestly.

I don't know how long it has been, but Empress Changsun slowly shook her head and let out a light sigh, her eyes were faintly red.

"Cheng Sanlang, you really have a heart...... It is a good fortune for Cheng Qian to have him as a friend......"

"What the queen mother said is that although Brother Chu Bi has a bit of a temperament on weekdays, he ...... to his father and eldest brother."

"I don't know, your father also knows." Empress Eldest Sun smiled. "I just didn't expect him to be able to do this......"

Empress Eldest Sun gently stroked the smooth paper and said.

"Even the movable type printing is useless, and the good and humble paper patterns he has produced are enough to make the scholars of the world happy."

"I will personally go and tell your father, don't worry, my mother will leak the news for you in advance and keep it a secret."

Hearing this, Li Ke, who seemed to have eaten a reassuring pill in his heart, couldn't help but be overjoyed, and hurriedly saluted the eldest grandson queen respectfully.

"Thank you for your understanding."

"You have a close friend and a father in your heart, how can I not help you." Empress Eldest Sun took two steps forward and helped Li Ke up with relief.

When Empress Changsun came to the Ganlu Palace, Li Shimin, who had not been retired for a long time, was still correcting the recitals in the Ganlu Palace.

Seeing Empress Changsun walking slowly, she couldn't help but smile and put down her smile. "Guanyin, where's the little son?"

Empress Eldest Sun stepped forward with a smile and offered the bamboo tube in her hand.

"She's playing in the garden...... Husband, the concubine is here, and there is a treasure that I want to dedicate to Your Majesty. ”

Li Shimin was happy, took the bamboo tube, and said while pulling out the lid of the tube.

"Oh? Could it be that you got some ancient scroll or can't you get a book? ”

When Li Shimin opened the bamboo tube cover, he pulled out the paper sample there and saw the handwriting on it.

After seeing the song "On My Father's Order, Cheng Saburo Sent His Father Cheng Biting Jinxi Out of Chang'an", he laughed out loud with joy.

"What's going on with that kid Li Ke? He actually transcribed this poem and sent it to me. ”

Seeing that the husband was just looking at the music of the poem in that cracked mouth, he didn't notice what the point was.

Empress Eldest Sun couldn't help but smile and shook her head slowly. "Husband, that's not the point, you can take a good look at ......"

"Not the point?" Li Shimin looked at his dear lady with a confused expression, and then carefully looked at his own Ke'er's handwriting.

Half a day later, Li Shimin was very sure of his authenticity. "Hmm...... This kid's calligraphy has not been seen for a few months, but it is quite beneficial. ”

The eldest grandson queen, who was supposed to be gentle and virtuous, raised her hand expressionlessly at this moment, and pressed the green tendons that appeared at the corners of her forehead.

Empress Changsun finally understood that her husband's observation seemed to have gone astray, so she had to go straight into the tunnel with a single knife.

"Husband, don't you really notice the difference between the paper in your hand and the tribute paper?"

"Tribute paper...... Tribute...... What kind of paper is this? Li Shimin finally reacted after carefully looking at the paper pattern in his hand for a long time.

With a look of surprise, he repeatedly looked at the paper pattern in his hand, and always felt that the quality of this paper should be inferior to that tribute paper, but it was better than those ordinary papers.

Seeing her husband's shocked expression, Empress Eldest Sun finally felt that her thoughts had reached a lot, so she smiled gently.

"This is Cheng Sanlang, who improved the papermaking technique of the Cheng family paper mill a few days ago, and made the new Cheng family paper."

"That kid, he can make paper? It can't be a joke......" Li Shimin almost laughed out loud, but he saw Guanyin's calm face.

The sneering smile on Li Shimin's face gradually faded, and he looked at the paper in his hand in a daze, and the reassuring voice of Guanyin came from his ears.

The price of Cheng's paper, as well as the reasons why he improved papermaking, will be explained one by one.

Li Shimin looked at the paper pattern in his hand, and even picked up the pen and wrote a few words next to the poem.

It was observed that the ink was soaked in the paper, and it was not smudged, but was able to outline the handwriting well.

At this moment, he couldn't help but shake his head again and again in disbelief.

This new style of Chengjia paper, the cost of one zhang is only eight or nine Wen, which is enough to pay tribute to the paper, which is five or six times lower.

You must know that the reason why books were precious in the past was that the tribute paper was expensive, and the second was that it was laborious to copy.

But now, the paper pattern that Cheng Chubi kid made for lead movable type printing is enough to shake Li Shimin's heart.
