This is really not something that ordinary people's brains can come up with, the important thing is that there is someone whose brain can open so big.

I saw that the seal was stamped on paper, and from this the movable type printing was invented, and because the cost of paper was too high.

actually went to improve the papermaking technique by himself, and the important thing is that this kid is just using the days to treat Shiro Li Tai.

took the time to get it, such a skill, it made Li Shimin want to see what magical things were in Cheng Sanlang's head.

"Although the husband has never seen the movable type printing, according to what Guanyin said, the husband can be determined.

The cost of movable type printing will inevitably be much lower than that of engraving printing. ”

"With such high-quality and inexpensive paper, combined with low-cost movable type printing......"

"Even the old man, he can't help but be a little jealous of the good fortune of Chengqian."

Li Shimin paced in the manna hall in disbelief, looked at the paper pattern in his hand, and shook his head again and again.

Seeing that her husband was already so excited that she couldn't sit still, Empress Changsun glanced at the direction of the palace gate and reminded her in a low voice.

"Husband, don't forget, the concubine body promised Ke'er."

"Oh, I'm a little excited for my husband." Li Shimin nodded and sat back in front of the desk.

The big hand gently patted the paper pattern, and said with a relieved face. "This Bi Xian nephew is really a lucky star for our family."

"No, Cheng Saburo, he is His Majesty's lucky star." Empress Eldest Sun looked at her husband in front of her, and said seriously and solemnly.

When Li Shimin heard this, he couldn't help but nod his head approvingly.

"Don't worry, how can a husband be jealous of his son because he can stabilize the position of the prince and win the support of scholars all over the world?"

"He is the crown prince, the prince of the country, and in the future, I will hand over the whole world to him personally."

"If he can win the public's expectations, I will only be happy for him."

Empress Eldest Sun stretched out her hand, clasped it tightly with her husband's hand, and said with a smile.

"Of course, the concubine knows what kind of person her husband is, and it must be Your Majesty's favor from heaven, and I, Datang, can only be helped by a genius like Cheng Saburo."

Li Shimin was very happy, stroking his long beard, and his spirit was radiant.

"Yes, if it weren't for my discernment and letting him enter the Shidong Palace, how could that kid's series of shocking actions be called shocking?"

"This is natural, because of a generation of wise and talented monarchs like Your Majesty.

I Datang, there will be so many capable ministers and famous generals, and there will be today's prosperous atmosphere. ”

Li Shimin smiled heartily, looked at the paper pattern in his hand, and took a deep breath.

"Having said that, my husband is really eager to look forward to Cheng Qian's foot getting better soon......

"Those important ministers of the court, if they see Cheng Qian striding forward and offering that movable type printing, their expressions are really exciting......

Seeing the expression of schadenfreude on her husband's face, Empress Changsun lowered her eyes speechlessly, he was still the emperor, but what could he say......

Hehe...... Men, as expected, will never grow up, even if they have children, they will be like children.

"Guanyin, what are you thinking?" It took Li Shimin half a day to put away his smiling face and look at his wife in his arms.

The eldest grandson queen smiled, her smile was so virtuous and gentle. "It's nothing, the concubine just thinks that what you said is right, husband."

"Really?"

"Of course it is."

Seven days after Li Tai's surgery, Cheng Chubi stayed in Chang'an under the pretext that he needed to wait for Li Tai's wound to heal.

Standing in the printing workshop of Cheng and Xu Hegu on the bank of Fengshui, looking at those craftsmen, they began to turn the machinery with their feet.

A round roller slowly turned, as a craftsman carried a piece of tissue paper down the feeding slot.

In everyone's astonished gaze, the piece of paper was actually sucked onto the roller out of thin air.

And with the turn of the roller, the tissue paper was rolled over the lead movable type plate that had been brushed with the ink that had just been developed.

When this series of actions is completed, the sheet of paper, which has already been printed, is stretched out, separating it from the roller.

The first sheet was separated, and the second sheet was taken away by the roller......

After printing seven or eight footprints, he began to see the ink fading, and Cheng Chubi stopped at this time.

Then, the first printed tissue paper was quickly handed to Cheng Chubi's hands.

Cheng Chubi's brows couldn't help frowning, and he handed the poorly printed test product to Li Ke beside him.

Li Ke looked at the paper in his hand in a daze, even the ink was still a little unsatisfactory, and some handwriting seemed blurry.

But the problem is that this is enough to prove that Brother Chu Bi's idea has really become a reality.

Moreover, they can see the engraving printing next to it, and every time a page is printed, it needs to be re-brushed.

And there are so many footprints here, even if the ink on the last two or three has faded significantly, it can still be inked.

"Brother Chubi, how could the roller suck that paper on it?"

"It's a static effect, for example, if you take a piece of leather and rub it against each other, it can have that effect."

When Cheng Chubi saw Li Ke's bewildered look, he couldn't help but be happy, and a sense of superiority in IQ arose.

"What the hell is that static effect? I won't explain it to you, mainly because I'm worried that you won't understand. ”

"......" Li Ke's face quickly darkened. muttered unhappily.

"According to your intentions, Brother Bi. Sucking up the paper is because of static electricity, so dare to ask what is electricity. ”

"Electricity?" Cheng Chubi took a breath like a toothache and looked blankly at Li Ke who asked this strange question.

God's special electrodynamics, Lao Tzu is not good at physics, but he also knows that there is only a description of static electricity in the textbook.

"Electricity is the thunder and lightning that you can see on a rainy day."

Cheng Chubi rolled his eyes, and finally thought of a very good explanation that was in line with the feudal superstition concept.

"I see...... Li Ke was stunned for a long time, and then he suddenly realized. No wonder lightning snaked through the clouds, just because it moved. ”

"Uh-huh, Brother Xian, you have a very good brain." Cheng Chubi patted Li Ke's shoulder with a kind and caring face.

"......" Li Ke looked at Brother Chu Bi in a daze, always feeling that he was sarcastic about himself, but he couldn't find evidence.

"I'm complimenting you, brother Xian, look at you like that, do you think I can still sarcastically mock you?"

Seeing Li Ke's expression, Cheng Chubi was happy and continued to think about serious things.

Although the quality of the ink still needs to be improved, and the machinery also needs to be adjusted, everything is developing in a good direction.

Cheng Chubi was very pleased to praise Uncle Ping, who was simple and unpretentious and liked to do big things in a low-key manner, and told him to continue to let those craftsmen work together to find a way.
