"What are you talking about?" Empress Eldest Sun was still a little confused, and she didn't know what tricks these two were doing.

Li Er also brushed it back, and looked at Li Yi tightly, for fear that what Li Yi said was not what he thought in his heart.

Li Yi didn't dare to sell Guan Zi, and quickly explained: "Uncle Li, in fact, this idea has long been available to the little nephew, because if Qianzhuang wants to develop, it can't do without paper, and the little nephew originally planned to study a kind of paper that can be produced quickly, and also increased the cost, but I didn't expect to create a paper that can be produced quickly and the cost is extremely cheap!" ”

"What?" When Li Er heard this, he was immediately excited, he originally thought that what Li Yi said was just to speed up the speed of papermaking, or reduce the cost, but he didn't expect that Li Yi actually did both, which is incredible.

Li Erqiang held back the excitement in his heart and shouted in a low voice: "Boy, don't sell it, if you have something to say, say it quickly." ”

"Yes, monthly money, the little nephew asked Lin Jiang, presumably His Majesty has also heard of it. The little nephew specially took him to Jinling, and then told him some of his nephew's ideas about papermaking, and gave him a large sum of money to concentrate on reforming papermaking, but what the little nephew didn't expect was that after only a month, they succeeded! ”

"How is the improved papermaking technique?"

"After the improvement, the cost of a piece of paper is less than three pennies, and the little nephew estimates that it can be pressed down, two pennies, or even one penny. As for the production speed, as long as there are enough manpower and workshops, it is not a problem to produce tens of thousands of sheets a day! ”

"Sanwen? Tens of thousands? "Li Er and Empress Changsun have been stunned, this is really a great joy, you know, the current rice paper has to be slashed several times, and even dozens of times have people to buy. And now? The cost is less than 300 Wen. (One knife of paper, one hundred sheets)

What is this concept? What excites Li Er the most is the production speed, the current technology, it takes half a year or even a year to produce a piece of rice paper, which is why rice paper is so expensive, of course, the cost is not low. However, now that these two problems have been solved, doesn't this mean that from now on, even ordinary people can use paper?

Thinking of this, Li Er instantly thought of infinite possibilities, with paper that can be used casually, which is definitely a cross-era progress for Datang.

Empress Changsun has been covering her mouth, her eyes are full of disbelief, she would never have thought that Li Yi is so powerful that he can improve papermaking, this is really scary, no other, based on this alone, Li Yi can definitely leave his name in history and be admired by future generations, Empress Changsun was surprised, but also couldn't help but be happy, his favorite daughter, Changle finally found a wishful husband.

"Boy, what's the quality of the paper produced?" Li Er is still a little sensible.

Li Yi hurriedly took out the seven pieces of sample paper from his arms and handed them to Li Er, Li Er grabbed them and looked at them one by one.

When he saw the last one, he was taken aback again. "How can the quality of this paper be better than rice paper, boy, what is the production speed and cost of this paper?"

Li Yi smiled slightly. "Your Majesty, what the little nephew said earlier is the production speed and cost of this kind of paper!"

"What?"

Li took the paper in the middle of the hand and sat on the chair in a daze, happiness came too suddenly, and he couldn't react.

Long......

"Hahaha!"

Li Er finally laughed, which also relieved his excitement.

After laughing, Li Er was able to ease up.

Stunned, Li Er suddenly raised his head. "Boy, who knows about this?"

Li Yi knew that Li Er would also care about this issue.

So he hurriedly explained: "Uncle Li rest assured, Xiao only knows the importance of this matter, from the very beginning, their research place was placed in the cave of the deep mountains of Maoshan by the little nephew, and the disciples of Maoshan were also sent to guard it day and night, and the disciples of Maoshan did not know what was inside, and the little nephew had already placed a strict confidentiality system. Therefore, no one knows about this matter except for those craftsmen and nephews. ”

That day, Lei Gang and more than a dozen divine arresters were left at the foot of the mountain by Li Yi, and it was also for their good to hide this matter from them, so Li Yi did not tell Li Er about it.

Li Er is very relieved of Li Yi's ability to do things, Li Yi can always think about things very thoughtfully, just like cement, since Li Yi researched this thing, he immediately put down confidentiality measures, so that although there are cement workshops everywhere now, the most critical technology is still in the hands of his own people.

"Well, you do something, I don't worry. However, it is not very safe for this cement workshop to stay in Maoshan! ”

As an emperor, Li Er naturally hoped that this kind of thing would be as close to him as possible.

"Yes! In this way, the next time the little nephew comes back, he will bring them all back to Chang'an! ”

Li Er nodded with satisfaction. "However, your Maoshan disciples are still not safe, after all, they don't know much about this. Such. I have sent you a battalion of Qianniuwei to defend the paper mills. ”

Li Yi knew that Li Er wanted to take the papermaking technique for himself, but Li Yi did not object, and taught this thing to Li Er, he was safer, as long as he was allowed to use it.

"This is great, the little nephew has been worrying about this time?"

Seeing Li Yi know each other like this, Li Er suddenly leaked a smile, he appreciated Li Yi's attitude of knowing current affairs, Li Yi knew what he should ask for and what he shouldn't.

"By the way, what does this have to do with the family?"

With papermaking, it is natural that many things can be done, but it is still impossible to control or even eliminate the family with these.

"Uncle Li, the biggest influence of the family on the court is that they control the talents of the whole world, whether it is the children of the Han family or the children of the family, they are all controlled by them, which is why most of the officials in the court are their children! However, after all, the children of the family in this world are in the minority, most of them are the children of the poor family, and the reason why they will be controlled by the family is because they can't afford to read, and it can even be said that they don't have books at all, so they have to bow to the family, but with papermaking, you can fundamentally solve the problem of the poor family looking down on books, and once they can read the books themselves, who wants to send people under the fence? ”

Li Er smiled slightly. "Yes, you've always had a sharp eye for things, and you've said it before. It's just that what you kid thinks is still too simple, and if you want to make a lot of books, papermaking alone is not enough. ”

However, Li Yi did smile. "Uncle Li is talking about printing?"

"Yes, it's printing, huh? What do you mean kid? You won't be? ”

However, Li Yi did nod his head again.

Naturally, Li Er was stunned again!
