Niu Da and Niu Er retreated, but Wang Pu was left behind by Li Yuanjia.

Sitting on the chair that the carpenter had just adjusted, although Li Yuanjia looked at Wang Pu opposite and was standing uncomfortable, he would not ask the other party to sit down, but took a sip of water and asked lightly: "Wang Pu, do you know what I asked you to do?" ”

"Yes, the king taught me how to make paper!"

After swallowing and smearing, Wang Pu immediately bowed down and replied.

"Yes, but not exactly!"

Putting down the teacup in his hand, Li Yuanjia raised his eyebrows and smiled: "If it's just for papermaking, why should I send you over?" Could it be that without you staring at the side, Niu Da Niu Er would not be able to make paper, or dare to be lazy? ”

“…… Naturally, they didn't dare! ”

After a pause, Wang Pu immediately shook his head.

If there are many people in the papermaking workshop, it will be enough, and some people will naturally dare to be lazy under the mixture, but now there are only two craftsmen, Niu Da Niu and two craftsmen, and the king personally ordered, unless they want to be boarded, otherwise the paper can not be made or the quality is not good, it is their sin! So Wang Pu can be sure that not only will the two not dare to be lazy, but they will definitely take it seriously and work hard to make the paper as soon as possible!

This is Luzhou, and no one dares to fool the king.

It was precisely because he understood this that Wang Pu was puzzled by the king's order, and he couldn't figure out why he wanted to "assist" those two rough men. After all, in his opinion, although he is not a person who reads poetry and books, but he can read words and hyphenation, and know some mathematics, why wouldn't he go to papermaking?

Although I didn't dare to disobey the king's order just now, I was sure that I was uncomfortable.

"So, there's another use for you going."

With a wave of his sleeves, Li Yuanjia simply stood up, and after turning around the chair twice, he suddenly stopped and said: "Wang Pu, making paper is just a trivial matter, and it is enough to have a big cow and a cow, but improving papermaking and making paper better and more, that's what you have to do, understand?" ”

For these papers in the Zhenguan period, Li Yuanjia was not very satisfied.

Even if it is the best paper on the market, it is not very attractive in Li Yuanjia's eyes. Not to mention that the eye color is not white enough, a lot of paper is either too brittle, or the water absorption is too good, and the pen and ink will spread out badly. And more importantly, paper is too expensive these days!

Therefore, Li Yuanjia not only wants to make paper, but also "improves" the process of papermaking.

“……”

Raised his head in astonishment, Wang Pu looked confused!

What do you mean?

Let me improve Niu Da and Niu Er's papermaking skills, and they will make more and better? This, how is this possible?

Looking at his stunned look, as if he had guessed what he was thinking at this time, Li Yuanjia smiled and said, "Do you think this is impossible?" Can't do it yourself? ”

"Goo-dong!"

This time the saliva was extremely difficult to swallow, and Wang Pu said with some trepidation: "Big, king, if I don't shirk it, it's really ...... I really don't know anything about papermaking, let alone improve it, but it will take a lot of time to learn it...... I'm afraid of delaying the errand you assigned by the king! ”

"Hahahaha......"

After listening to Wang Pu's words, Li Yuanjia laughed.

Perhaps for the ancients, like any other craft, it seemed to be quite difficult. For example, to be a blacksmith, or to learn to be a doctor, often have to be an apprentice for a few years first, and be squeezed by the master for a few years, and then learn something, but people really have the ability to press the bottom of the box, it must be left to their son, can the apprentice or something provide for me? This is also the reason why Niu Da Niu Er's face will be so ugly after hearing Li Yuanjia's order just now.

It's just that they don't dare to disobey the king's orders.

However, for Li Yuanjia, a traverser, is papermaking difficult?

If it's a video, it's not difficult!

In his previous life, he had read countless travel novels, and almost half of the protagonists would involve papermaking or movable type printing, and because of curiosity, Li Yuanjia even looked for CCTV's ancient papermaking video on the Internet to study whether it was really so easy to get.

And the answer, of course, is yes, it's that easy!

It is nothing more than peeling bark, washing, drying, rinsing, soaking, steaming, crushing, pulping, scooping, pressing water, unwrapping paper, baking......

To be honest, although he doesn't remember it very clearly, Li Yuanjia believes that once he is asked to see Niu Da Niu Er's operation, he will definitely be able to remember it quickly - after all, although the history of Chinese papermaking is more than 2,000 years, the basic process has never changed, and it has become just craftsmanship and details.

And for Li Yuanjia, he also knows some tricks to improve.

For example, quicklime should be added when boiling, which can remove organic matter from the bark, and for example, before scooping the pulp, some plant extracts can be added to the pulp to make the pulp viscous, and the ink will not spread on it after the paper is formed......

It doesn't sound or look like it's that hard.

But......

Is it really that easy?

As early as when Chang'an was preparing for all this, Li Yuanjia only took two days from the optimism at the beginning to the prudence later, because he suddenly remembered one thing - if an ordinary person goes to see a simple surgical operation, such as trauma debridement and suture, does he think it is very simple? Anyone who learns it can do it?

How can it be?!

Many things are easier said than done. It's like using a curtain to pick up the pulp at the end, stacking the freshly formed wet paper, pressing off the moisture, and then peeling it off one by one to dry it, which is not easy without experience and technology. For example, the heat of boiling, the time of soaking, the composition and proportion of various additives, etc., Li Yuanjia only knows such a thing, how to operate it......

It's helpless, and I've forgotten it over time.

So if you want to make paper, you still have to rely on a veteran like Niu Da Niu Er, otherwise if you really let Li Yuanjia come by himself, you will definitely be able to do it in the end, and maybe you can do it better than Niu Da Niu Er, but how much time will it take him and how much energy will it take?

After all, a complete papermaking process can take quite a long time.

But fortunately, the current king is not the king who can only read, write, draw and paint, Li Yuanjia, who has a lot of experience in mixing scientific research funds in his previous life, can easily formulate a "scientific research plan" to improve papermaking - decompose the papermaking process into small programs, and then try for each step.

For example, adding quicklime or other things to the comparison when cooking, trying the juice of various plants when beating, and trying to replace the hemp and bark that are most commonly used today, with bamboo, etc.

So in the face of Wang Pu's shock and panic, Li Yuanjia laughed a lot, patted him on the shoulder a little forgetfully, and then said when Wang Pu was shocked and a circle of sweat broke out on his head: "Don't worry, I will tell you what to do when I go back, at most, it will take a few years of hard work, and it will definitely work." ”
