Datang violent otaku

For the next two days, Li Feng was still busy.It is not difficult to make chalk. There are gypsum and lime, just get it.These things were directly handed over to Rou Niang, and she was asked to play with a few little ones.

With chalk, it still doesn't work. Only chalk without a blackboard is useless.Speaking of which, the invention of the blackboard is more meaningful than chalk.However, its emergence can be regarded as a major change in teaching methods.Let the previous boring and inefficient teaching mode, which only knows how to shake your head and read, be reborn.

Through the blackboard, teachers can express knowledge more vividly and effectively.Not only can you use text, but you can also use graphics, etc., so that students can learn more easily, understand it more easily, and even remember it more deeply.

The production of the blackboard is actually not difficult, just get a large flat board, and then evenly paint black paint on it, after drying, hang it in the center of the classroom and you are done.

It's just that, in order to make the blackboard better, bigger and smoother, Li Feng specially called Master Qi, and then slowly started to mess with it.Of course, there is also the time to wait for the black paint to dry out.

"Come on, Yaya, go get some chalk, let's try it"

Looking at the familiar blackboard in front of him, Li Feng felt a little impatient, and quickly asked Yaya to get the chalk, wanting to try it out, the feeling of these chalk characters.Haven't touched either of those things since finishing high school.

"Yaya, take more, I want to write with chalk too"

"Sis also needs to be written, little aunt, I'll go get it with you."

"That's right, Sister Yan is the laziest. My elder brother said that you have enough food and clothing by yourself. If you want to write, you can take it yourself. We won't help you with it, lest you become more and more lazy."

After Yaya finished speaking, she immediately took her little son and ran into the house to get chalk.

"Stingy ghost, if you don't help, you won't help. If you have the ability, let's compare later, who can write better."

"Bi, I'm not afraid..."

After a commotion, the three of them ran into the house, and then quickly came out again.Yaya immediately handed Li Feng some chalk.However, the three of them did not move, but looked at Li Feng carefully, wanting to see how to write.

"What should I write, um, I have it"

Holding the chalk and staring at the blackboard, Li Feng was suddenly confused, not knowing what to write.This can be said to be a moment that created a precedent in history. Whatever it is, I have to write some profound words.However, soon, Li Feng knew what to write in his heart.Pick up the chalk, and write a line of words on the position directly above the blackboard.

"That's right, that's right. It takes ten years to grow trees and a hundred years to cultivate people, and education is the foundation of a hundred years' plan. Come on, Yaya, give Seventh Grandpa this chalk too, and Seventh Grandpa will come to practice too."

After seeing the words on Li Feng's blackboard, Qi Ye immediately praised him, thinking to himself, that's a good word.However, soon, he also felt a little itchy, wanting to try this so-called chalk writing.

"Ah...why is this chalk so brittle, Yaya, give Grandpa Seven another one, I won't believe it, and I can't write this chalk character."

This chalk writing looks very simple, but it is not easy to write.Especially for an ancient person like Qi Ye who has been writing calligraphy all his life.It was quite difficult to use this chalk. No, Qi Ye broke a piece of chalk before writing half of it.

The old man was not convinced now, and immediately took another piece of chalk from Yaya, and then broke several pieces of chalk, before he managed to write a few crooked characters.As soon as he finished writing, Qi Ye immediately erased it. There was no way, the words couldn't be seen by anyone at all.

"Hey, forget it, it seems that this chalk writing is really difficult to write. However, this thing is really good. Take a look. When you want to write, just write on it. After writing, just wipe it with your hand. It's gone, you can continue to write. Ah... Yes, Ming boy, we can get everyone a small blackboard like this and put it on the table in front. When you want to write, just write with chalk , After writing, just erase it."

"Haha... In this way, there is no need to use paper at all, and even pen and ink are saved. After reading, there is no need to spend money at all, just make more chalk, isn't it all right? You said yes no?"

Qi Ye originally wanted to avoid the important thing, change the subject, and never mention the matter of his writing.There is no way, compared to those written by Li Feng, his writing is really ugly.While talking, he actually thought of a coup.Let each student have a small blackboard.In this way, I really saved pen, ink, paper and inkstone.

This pen and paper, what are they in modern times? They are rotten and cheap things.However, in this ancient times, the prices of these things were simply ridiculously high.A small piece of ordinary rice paper costs a penny, and a hundred sheets cost a stone of grain.

For this, Li Feng has a deep understanding. At the beginning, Li Feng cursed secretly for a while because the paper was so expensive.If it weren't for the family's money, ordinary people would simply not be able to bear it at the rate Yaya consumed paper.

"Haha, Qiye, your idea is good, definitely good. In this way, a big problem will really be solved, and some people will definitely be overjoyed. However, in this way, the desks used by the students will be It has to be done properly, otherwise after a class, you will be covered with chalk dust. Also, this is not good for your health. We have to think about how to design this desk to eliminate these Questions do."

Qi Ye's idea is brilliant. In this way, the cost of studying can be reduced to the lowest level, and Li Shimin will really be overjoyed.

It's all thanks to Lord Qi, if Li Feng was allowed to do it himself, he would never have thought of such an idea.This is a kind of thinking inertia. After all, in that era, who would worry about a few pieces of paper and a pen.Worrying is all about the living expenses and tuition fees needed to go to school.

"Okay, old man, I'll arrange the manpower and prepare the wood immediately. As for how to get the desk, I'll leave it to you."

Qi Ye was a little impatient now, and regardless of whether Li Feng would or not, after leaving Li Feng with the task of designing the desks, he trotted away.

After Qiye left, Yaya, Sizi, and Gao Yang immediately picked up chalk and started their writing competition on the blackboard.In fact, no matter it was Yaya, Sizi or Gao Yang, they had never worried about the pen and paper, and they had no idea what these things meant to ordinary people.

However, it is not so easy for Li Feng, Qi Ye entrusted him with the job of designing the desks.This is a very urgent matter, and it cannot be sloppy.Perhaps, Qi Ye and the others don't care at all whether the desk fits well or not, whether it will stain the clothes, whether it will let the chalk dust fly around, and so on.

However, Li Feng knew that this matter could not be sloppy.Especially the latter shortcoming, we must find a way to solve it.

"Well, first of all, there must be a special slot for chalk dust on the desk, and secondly, a good blackboard eraser. Some things must be kept after writing, so they can't be written in the small box. Blackboard. In this case, paper and pencil must be used, so another clean board must be prepared. …”

As Li Feng considered various factors, the thoughts in his mind became clearer and clearer.
