This frightened him, he hurriedly reprimanded him, carried Liu Feng out, exaggerated Liu Feng's goodness, and told them to keep themselves safe and work hard.

"Good job!" Liu Feng put down the document, which contained some material data, as well as the general situation of the slaves. He did not expect that among these slaves, more than 400 people were orcs.

Liu Feng couldn't help but sigh that the prince named Dies was really cruel. In order to disguise his whereabouts, he actually treated orcs like slaves.

"By the way, are there many people who go to your school to learn to read?" Liu Feng asked Buff, this literacy rate should be the focus of attention.

"Many, many people go during the day now." Speaking of this, Buff was very excited. He didn't expect that so many people would be willing to read words.

"So, how many people do you think will be able to read after this winter?"

Liu Feng folded his hands and asked, "Can you make half of the people in Xiyang City know the characters?"

"This..." Buff frowned, counting the number of literate students in the school in his mind, and finally shook his head and said, "Lord City Lord, after the winter, only two adults should be able to read."

"Is the school not enough?" Liu Feng asked.

"Yes, the school can only accommodate fifty people at a time. If there are more, there will be no space for everyone to practice calligraphy." Buff sighed. After all, the sand table takes up space, and the most important thing is that everyone has no books.

Now only primary schools have books, and the rest can only go to the school to write and practice, and they may forget it when they go back. This is the most time-consuming.

Liu Feng also thought of this problem. Movable type printing is still missing the last hurdle, and that is the problem of ink.

For example, the cost price of books printed in elementary schools is very high, mainly because the ink raw materials are relatively small. The scientific research department is now preparing a relatively cheap ink, which is already in the experimental stage.

As long as the cost price falls, it is time to promote it. Otherwise, a book will cost the cost of one silver coin, and a few more silver coins will be sold. Who among the commoners can afford it?

"Bang bang bang!"

Just when Liu Feng was thinking about how many more schools to set up, there was a knock on the study door.

"Come in!" Liu Feng said softly.

"Gag!"

Mina walked in, holding an iron box in her hand. She had just returned from the scientific research department, and some secret documents had to be passed on by her.

"Master, the scientific research department has something for you." Mina put the iron box in front of Liu Feng, then sat on the desk with her hips raised, her cat's tail twitching.

"Oh?" Liu Feng raised his eyebrows, thinking that something like that was made? He flipped the combination lock, lifted the iron cover, and saw two or three things lying inside.

"Huh? It's actually this." Liu Feng said with a smile, "It's really just in time for the rain, whatever is missing."

He took out the otherworldly version of the pencil from the iron box, no, it should be a charcoal pen, or a charcoal pen rolled out of paper.

"Master, what is this?" An Li, who was making a record, leaned over and looked at the little sticks in Liu Feng's hands, as well as the boxy block of wood.

"It's called a scroll charcoal pen, but it's a good thing. It can solve the problem of writing for many people." Liu Feng shook the scroll charcoal pen in his hand.

"Can this thing be written?" En Li took a stick and looked puzzled, "Master, both ends of this thing are flat, how can I write it?"

"This is going to use a pencil sharpener." Liu Feng picked up the small wooden block beside him. The principle and method of the pencil sharpener were very simple.

The paper roll charcoal pen was stuffed in, and the scraps of paper fell out as soon as it was turned, and soon the tip of the pen was sharpened. Liu Feng pulled a piece of paper and wrote on it, and a line of elegant black characters appeared.

"Wow? This..." En Li stared at her brown eyes in surprise. She picked up the pencil sharpener and began to sharpen it. It was quickly sharpened, and she began to write again, but the end of the pen broke with a little effort halfway through.

"Don't push too hard." Liu Feng chuckled and handed the pen to Buff, asking him to try it too.

"It's amazing, it's so convenient..." Buff complimented after writing.

"Use this to scratch off the writing." Liu Feng picked up two thumb-sized iron pieces and handed them to An Li and Buff.

"Huh? What a miraculous pen." En Li used an iron blade to easily scrape off the handwriting, which surprised her again and again.

"Lord City Lord, if there is such a pen, everyone can copy the words home and practice." Buff said in surprise.

"Of course, the price of this kind of pen is not very expensive." Liu Feng nodded, he couldn't make a pencil, and lacked the raw material of graphite.

Don't even think about it like a ballpoint pen. It's fine to use it in my own castle. If I promote it, I'm afraid it will kill him. He doesn't want to be a cargo porter. He wants a ballpoint pen today, a pencil tomorrow, and the day after tomorrow. want that.

Therefore, Liu Feng felt that in this era, it is practical to produce and promote things that can be produced. As for the earth's goods, it is enough for one's own use.

The tip of the ballpoint pen, on the other side of the earth, is a high-tech thing, which can be regarded as stuck to him.

In the case of fountain pens, the scientific research department is still debugging the nib, as well as the matching ink, and the problem of sealing the ink, etc. It will take a long time to really study it.

These two are not good, but the charcoal pen is still possible. The charcoal is crushed into powder, and the clay is added into the stirring shape. It is extruded with a special mold and then rolled up with paper.

Compared with writing directly with charcoal, the characters written by the paper roll charcoal pen are darker. Because of the clay, the writing is smoother. After all, the overall density of charcoal is worse than that of the paper roll charcoal pen.

Although it is a little worse than the reed stick pen and the quill pen, these two types of ink-dipped pens, but the worse is the writing quality problem, that is, the font is difficult to preserve.

In contrast, the paper scroll charcoal pen is cheap and simple, and it is not limited by the problem of ink. After all, ink is not affordable for the common people, but only the nobles and wealthy businessmen can afford ink.

"Buff, I will open two more schools, and the paper scrolls and charcoal pens will be paired soon. I want at least half of the people in Xiyang City to be literate by the spring of next year." Liu Feng said solemnly.

"Yes!"

Buff replied respectfully, with this magical pen and two schools, he can still complete this task.

Every time he felt that some difficult-level problems could be solved quickly by letting the Lord of the City go out.

Now, when he goes back, he can brag to his grandson again, that stinky boy, doesn't know how he was at school today? Won't you bully other classmates again?

Chapter 0290 Catherine is sick.

"Crash~"

The sound of the hull breaking through the water waves sounded, splashing water and flowers.

In the cabin of the main ship, the atmosphere was extremely depressed at this time, because Catherine, the daughter of the most distinguished grand duke and one of the five strange women in the capital, was ill.

"Hahahaha..."

Catherine was lying on the bed with a pale face, breathing heavily, her face was full of pain, her thin eyebrows were wrinkled, and even the sound of her breathing could make people feel her pain.

"Catherine, don't worry, hold on for a while, Xiyang City is coming, there must be a very good witch doctor there, you must persevere." Darlene clenched Catherine's slender hand and comforted her softly. write.

Catherine caught a cold from the heavy snow the day before yesterday. For the first day or two, she was still a little dizzy, and she was weak when she spoke. She wanted to sleep.

Unexpectedly, Catherine's condition worsened today, and she fainted and fell asleep. Darlene didn't know until she came to Catherine in the morning.

Darlene was a little overwhelmed. This was the first time she had encountered such a situation. In the past, a disease like this was just lying in bed and stuffing it with a quilt for a day or two and it would get better. concoction.

But now Catherine's painful expression is really worrying. If there is an emergency... it will really happen.

"Boom bang bang..."
