It was another Sunday, and Ivan turned down Hudson's strong invitation. Try to see if papermaking can be used, if you can, don't say anything else, but it's okay to make money.

Ivan inquired about some things in advance and bought some fodder for the horses, mainly straw, and only spent a little copper plate. Take it to a grinding workshop and ask someone to grind the straw into crumbs and soak it in water.

As for the absence of lime, Ivan inquired about some alchemy products that had a similar effect. Limestone is something like that, and no one has ever heard of a stone with similar characteristics. If you have a long vacation, but you can go home and give it a try.

However, even so, it stands to reason that the original paper can be made. Seeing that the grass stalk crumbs were not broken enough, Ivan had soaked them all morning and then had them boiled in hot water, stirring vigorously as he processed.

After cooling, take it out and put it in four basins, one group is not added, and the other three gradually add three alchemy items. Each time you add it, take out a partially flat but flat slate and flatten it with a slate. It is divided into five additions, and it is marked.

Out of the need for secrecy, this part was all done by Ivan himself, and no one was watching, in fact, no one was curious, he just thought that it was a child who was blind, and he paid for it anyway, and he didn't do it in vain.

Fortunately, the sun was warm on this day, and all the test samples were dried in the evening before they were dried. Ivan carefully removed it and frowned. Maybe the straw is not very good, the finished product is brown, and because the grinding is not fine enough, it is relatively rough. Ivan tried, barely able to write.

put away his experiments, this experiment can only say that I can see some signs, and what straw and additives to use needs to be reconsidered. And the production process is too rough, so I have to find a way to make some tools.

In fact, Ivan knows very little about papermaking, but he only roughly knows what it looks like. Ivan hurried to the bookstore and borrowed a book about plants, a book on alchemical materials. Then I went back to school.

"Encyclopedia of Common Plants", there are also simple illustrations in it, Ivan took the time to quickly read it, and finalized the leaves or straws of the three plants. One is a wheat-like agricultural product, the seeds of which are the raw material of white bread, but they are shaped like beans, one is a plant that is used as a vegetable, and finally the leaves of a tree.

Then there is the selection of alchemy materials, two are selected by describing Ivan, and there are three kinds of ones with better results in his own experiments. Finally, I designed a production process that I had optimized and listed the requirements for the tools.

After sorting it out, he wrote a letter to his father along with his idea of making paper and his speculation about lime. Of course, I don't say that I made it on a whim, but I guessed it by seeing a record in an ancient book, and attached a sample of my own production.

"I said, Ivan, what are you doing mysteriously these two days? Hudson finally couldn't help but ask Ivan.

"It's just that you're always busy learning magic, and you've been out of the past two days. Bill couldn't help but say.

"A small invention, there is no result yet, let's talk about it later. ”

"What inventions? What inventions can you do? You're not an alchemist. Hudson said in surprise.

"Don't ask any more questions, it's not too late to wait for a while to get the results. ”

——

Frank Manor.

Duke took the letter from the messenger and found that it was Ivan who had written it to Old Frank. Hurry up and show it to old Frank.

"Sir, it's a letter from little Frank, maybe it's to report your safety, maybe it's missing you. ”

Old Frank laughed, "This kid must have spent all the money, if he didn't have the money, he would have remembered me? ”

"Look at what you said, I think little Frank is quite sensible, this is just a normal family letter. "Duke hadn't seen Ivan spend, so I couldn't stop Ivan spending so fast.

Old Frank said no, but in fact he thought to himself: This kid only now remembered to write to me, he really has no conscience! But the letter is so thick, nothing must have happened.

Quickly unwrapping the envelope, Old Frank frowned more and more as he looked at it. Duke saw that old Frank had a bad face, and hurriedly asked, "Is something wrong with little Frank?"

"Not really, look what he means. Why can't I understand what he's saying?"

Duke hurriedly took the letterhead, "This...... Does little Frank want to make paper? That's what it means. ”

"Of course I do, but why would he write such a thing? I can't figure out why he'd be interested in this stuff!" Old Frank was confused. I was looking forward to my son's letter, but when I opened it, it was a mess.

"Maybe little Frank is interested in alchemy? Aren't alchemists fond of doing strange experiments? ”

"This kid doesn't study magic well, and he messes with useless things. Old Frank said indignantly.

"Actually, I think this stuff written by little Frank is very powerful, although I don't know much about it, but I feel very convincing. If the child's enthusiasm can't be discouraged, let people try! If it doesn't work, it's play, and if it does, it doesn't mean that little Frank is a genius. Duke felt that what Ivan said was very organized, and he didn't know how to do it, so it didn't hurt to try.

In the end, old Frank went to the boy and asked the servants to go down, and tried one by one, and the servants really came up with something.

A servant showed old Frank a thick stack of papers. "Master, you did as you told, and these are the things that came out. ”

Duke saw some rough paper, and said with a little comfort: "Master, although it is not real paper, it is useless, but it looks like something, and little Frank is still very smart,"

"No, it's still useful. Old Frank said.

"Master, why do you say that, this is not comparable to real paper. Duke said puzzledly, it was just to comfort him, the master wouldn't take it seriously.

"This paper, although of poor quality, has almost no cost, and that's the biggest advantage. Moreover, this is only a preliminary product, we can study it more, as long as it can be written normally, it is a major invention. "Old Frank has been in business for a long time, and he saw the key at once.

"And paper is not only used for writing, on a certain cheap basis, paper will have a wide range of uses. Let's set up a few small workshops to see the results, and then we can continue to improve the production method. ”

Then Frank Sr. sent the results to the college in an envelope along with the samples.

A few days later, Ivan received a letter from his father, "Is the quality still too rough? It would be nice if I could improve it a little more, but I don't have that time, which is obviously not something that can be solved in a short time. I had to make a long-term plan. ”

As for the lime, it is true that it has not been found, and the stone only melts into magma after it has been burned.

Ivan sent some of his ideas and the idea of printing to his father, hoping that his father would find someone to study and see if there were any results.

After that, Ivan stopped focusing on these things that had nothing to do with magic. The study of the magic pattern and the cultivation of the magic circuit are the protagonists of the academy's life.

"Ivan, what is your mysterious invention? It's been a few days, is there a result!" Bill has always been curious, Ivan just perfunctory hope that he will forget in a few days, who knows underestimate this guy's patience.

"I saw in an old book about the ancient art of papermaking, and I tried to improve it. You think, if we had one book on all the basic subjects, how easy it would be to learn it!"

"No, you actually have the ability to do this! I really admire the five bodies of the earth, what about the paper you made? Take it out and let me see it. Bill looked startled at first, then began to rummage.

Ivan took out the sample and handed it to Bill.

"That's it! You really have nothing to do, can this be considered paper? Bill had a disgusted expression, you showed me this when you took off your pants?

"Quality is not the key, the key is the price, do you know how expensive the paper is now, how cheap mine is?"

Bill was a little unhappy when he heard this, "Of course I know, although my house is a clothing shop, it doesn't mean that I only know clothes." The users of book paper are basically wealthy people. A standard piece of paper generally requires three copper plates. If you were to bind a book, I mean blank, it would take a couple of silver coins. ”

"I don't have more than 10 copper plates for this kind of paper. What do you say?" Ivan picked up the paper and shook it in front of Bill.

"How is it so cheap, what do you make of??" Bill thought incredulous.

"It's really leaves, I've tried leaves, straw and some vegetable leaves. It was found that the straw had the best effect, and the leaves were similar. That's why it's so rough, but it can be improved. ”

Ivan was proudly introducing his invention to Bill when he noticed that the class suddenly became quiet. When I looked up, I saw that Lucia was looking at her with a "kind" smile.

"What do you say? Let the teacher listen to it too, and the teacher is also curious. ”

Ivan said curtly: "It's nothing, disturb the teacher, you are lecturing, I was wrong!"

"Bill, what are you talking to Ivan?"

Ivan hurriedly gave Bill a look, signaling him to just admit his mistake.

"Teacher, Ivan, he made a cheap paper, saying that it can be used universally!" After speaking, he even took out the paper to show off.

Ivan immediately touched his face with his hand, Bill really didn't know the situation, and there was no tacit understanding at all.

Lucia snatched the paper in one hand, "Your gadgets are confiscated!

Bill obviously didn't expect the teacher to suddenly turn his face, and he was a little confused for a moment.

"Didn't you just do well? I said I was interested, why did I suddenly get angry? ”

"I don't think I can save your IQ anymore. You just be a moody teacher. ”
