PS: The name of the previous chapter is repeated.,It's been modified.,This is the first change.,At least one more more!

Luo Heng opened his mouth and replied, "It's just a little invention." ”

"What invention!" asked Quison immediately.

"Cheney!" Quison had just finished his sentence when another voice rang out outside, Ryan.

"President Lane. Luo Heng opened his mouth to say hello, and he was speechless in his heart, why did he just come here and be chased by someone.

"I heard that there is a small invention, take it out and let's take a look at it first?" Ryan said directly.

Luo Heng took out a custom-made notebook, the paper was bleached, and then took out an ink pen.

Luo Heng wrote directly in the notebook, asking President Ryan of the Magician Guild to give him some advice.

Ryan and Quison had been staring at the paper for a long time, and when Luo Heng was writing on it, the two of them immediately realized the usefulness of this thing.

"Cheney, this thing has a lot of shortcomings, right?" Ryan took Luo Heng's notebook, flipped through it carefully, and asked.

"There are a lot of drawbacks, but it's cheap enough. Luo Heng said.

"How much does this cost?" asked Quison eagerly.

Ryan shouted dissatisfiedly, "President Quisen, please pay attention to your identity. ”

Ryan was really dissatisfied with Quisen, you must know that several major associations are now under the Alchemy Association, and his president wanted to get some benefits for other departments, so he was scolded back by Kuisen.

There's no way, the Alchemy Association is the most important department under the Wizards' Union, and Quisen's skills are also leveraged, and they can't be like other people who don't have any skills, so you can do whatever you want.

Quison pouted, knowing that there was no drama this time, but Quison was also satisfied.

"The cost price is thirty copper coins. Luo Heng said.

"Is this made of grass?" Ryan asked, with a shake of his spirit.

"Hmm. Luo Heng snorted and shut up about anything else, these guys are all ghosts and elves.

"So how big do you think the market is?" Ryan asked.

How big is the market, you have to ask how big the paper market is, just look at the paper companies on the planet.

"There are still tens of millions of gold coins. Luo Heng said.

"Are there so many?" Ryan asked, a little disbelieving.

"So what does the president think will happen to the sales of parchment with this kind of paper?" Luo Heng asked.

Parchment is expensive, and it costs a few silver coins to get a single one, so parchment is just a record of important things.

"This kind of paper can be developed better, caravan bookkeeping, destroyed after a year, no need to store it for a long time, you can also practice writing, you can also make books, said books, I have a set of printing methods here, can reduce the cost of a book by 80%. Luo Heng said.

So Luo Heng took out a book, which was printed by Luo Heng himself, similar to reading pictures and reading words.

"There are five hundred words on it, and the price is only fifty copper coins. Luo Heng said.

Quison and Ryan looked at each other, although the illustrations were just stick figures, but in the eyes of the two, they were very different.

The popularity of cultural knowledge in this world is too low and too low, and it can be said that except for the aristocracy, few of the rest of the people know how to read.

"How can it be so cheap?" asked Quison.

Luo Heng took out a printing press from the space bag, manually.

Then take out a piece of paper, put it in, and shake it with your hand.

An illustrated piece of paper appeared, then a second, a third.

"That's it, this copper plate can print many sheets at a time. Luo Heng shrugged.

Ryan opened his mouth and said, "Cheney, come with me, today is overtime, and I have to identify this thing." ”

Luo Heng had no choice but to follow Ryan to the Magicians' Union, and the big boss came in person, and the level of the people involved in the appraisal was very high.

The preservation of paper, the equipment for printing, the binding of books, and so on.

It had been five or six hours since the identification, and it was already midnight outside.

"SS-class!" Ryan exclaimed when he saw the results.

"Yes, President, according to our calculations, once this technology is promoted, then at least a billion people on our human side can have basic knowledge, such a book of graphic literacy can withstand 1,500 flips per sheet, and a person only needs to flip no more than ten times to recognize the words on it, that is to say, this book can be used by one hundred and fifty people, and one hundred and fifty people can each buy a book with different words, that is to say, they can master tens of thousands ......of words with fifty copper coins. The president of the appraisal association spoke.

Ryan was stunned, and Luo Heng was also very stunned, there was still such a way to calculate.

Quison was also stunned, fifty copper coins mastered tens of thousands of words?

"And just for ordinary life, the text is even cheaper, of course, some professional vocabulary, ordinary people do not need to learn. The president of the appraisal association continued.

"SS-class!" Ryan looked at the appraisal report, still feeling a little incredible.

However, Ryan also knew that the development of productive forces was inseparable from the popularization of writing.

How much financial resources are needed to learn cultural knowledge, for ordinary nobles, hiring a tutor, how can they get ten gold coins a year.

Of course, if it is sent to the academy, it will cost at least a dozen gold coins a year.

Of course, as an aristocratic school, there are many items to learn, such as horsemanship, combat, commanding, rescue, music, socializing, etc.

There will also be an additional charge for these items on the way.

Take the Academy of Magic as an example, although there is no tuition fee, but the cost of materials, accommodation, and social needs, Nicole, the daughter of a baron, all need more than 100 gold coins a year, which is still the lowest.

As for ordinary people, there are almost no opportunities to learn, of course, there are church schools or something, although there is no fee, but after learning, it is generally done under the church.

The reason why the Magicians' Guild is so deeply involved with the nobility is because only noble disciples have the opportunity to learn profound knowledge.

The profession of magician has high requirements for knowledge.

Where can ordinary people become magicians?

It's not that there isn't, it's very little.

"Then follow the SS level, and then form a book association. Ryan spoke.

Luo Heng didn't have anything, after all, the previous invention was like this, and after Luo Heng got his union badge, he was leaving.

"Don't go, Cheney, we're about to do something about the Dark Elves' dungeon, aren't you watching from here?" Ryan asked.

Luo Heng shook his head and said, "No, by the way, there is also this kind of paper, and the sales of this kind of paper are higher." ”

"This?" Ryan took the toilet paper in Luo Heng's hand, a little puzzled, what is this roll for, so soft, and still selling?
