When Lu Yun saw Li'er again, Li'er's eyes were bloodshot and with big black eyes, and he didn't sleep well all night.

He seemed to be looking at himself with some resentment.

Lu Yun laughed in his heart, I'm afraid that this thing was deliberately eavesdropping on himself yesterday, and he found that he couldn't hear it, and he has been haunting it, right?

"How did you sleep? Could it be that the bed is too hard?" Lu Yun asked kindly, looking like a corporal Lixian.

"It's okay, I'm used to sleeping. Li Er secretly looked at Lu Yun, but he didn't find anything special about Lu Yun.

But why can't I hear him anymore?

"That's good. ”

Lu Yun didn't say anything.

Classes after meals.

"Today we are going to learn, basic literacy. One goes two or three miles, four or five families in the mountain village ......"

......

Li Er could hear it this time, but he felt that Lu Yun's class was indeed different from others, and even he could understand it completely.

yi。

qu。

er。

san。

......

Li Er is well aware of the difficulties of children directly memorizing Chinese characters, but Lu Yun actually converted all these Chinese characters into symbols first, and let the children spell them by themselves. This kind of simplification, even if he is so old, he can probably understand it if he learns it again.

If you choose Lu Yun by yourself, you will definitely not be wrong, and you can't be wrong.

A day passed, and Li'er found that he was in Lijiahe and couldn't do anything.

He doesn't need to give advice, let alone listen to the enemy, as if he is superfluous.

"Lord Lord, if not, you can send something to do it for me!" In the afternoon, Li'er found Lu Yun and said.

Lu Yun put down the book in his hand, which was about medicinal herbs, and asked, "You just came, let's rest for a few days first." You also know the current situation of our Li Jiahe, temporarily self-sufficient, do you still want to plant trees and open up wasteland?"

"Alas!~" Li'er sighed.

Then he looked up: "Or, Lord Lord, how about I take charge of a class in the academy?"

To be honest, Li Er is a little itchy, according to Lu Yun's training, I am afraid that these children will not have a bad foundation in the future, as long as they are carved a little, I am afraid they can all become talents.

"Not yet. ”

Lu Yun immediately refused sternly, when the child lays the foundation, he must not be messy, Lu Yun naturally does not allow Li'er who does not understand his thinking to interfere.

Then, Lu Yun's eyes suddenly lit up and said.

"Li'er, if you're really bored, I have something here for you to control. ”

"What's the matter, sir, just tell me. As soon as he heard that something was wrong, Li'er hurriedly wrapped it up. Otherwise, wouldn't you be eating dry rice?

"You go and find some mud, divide it into balls, it doesn't need to be too big, and then find some craftsmen to divide it into small pieces, and carve them into small characters......"

"My lord, do you want to print books?"

"I have this idea, but it's not what you think. ”

......

The more I listened, the brighter Li'er's eyes became.

What are the reasons why books are expensive? First, people who read books are rich and noble people and don't care, and second, naturally, the effort to make books is too expensive.

Each edition of the book requires workers to spend ten days, or even daytime, to complete the engraving, which is naturally expensive, and it is also necessary to invite everyone to make a copy of the book.

Now Lu Yun said so?

Li'er even saw that in the future, the price of books in the world would drop by at least thirty percent, or even half, because of what he did today.

Then he himself will not be afraid of running out of money to buy books in the future.

"Don't worry, my lord, this matter is on me. Then he rushed out in high spirits.

......

Lu Yun thought about it for a while, many ideas from his previous life could be brought over, but he knew very little about the real technology, but this ancient technique of movable type printing, as long as the idea was right, it was not difficult to do.

As for the gunpowder, forget it, if it is in a low-martial world, it may still be useful, but in this immortal cultivation world, it is completely useless.

The territory is calm again.

Lu Yun was in charge of lecturing, the people in Liangmao Mountain were in charge of fishing, and the people of Li Jiahe were busy in the fields and mountains, and there was a peaceful scene.

Moreover, everyone can see that in just half a month, those fresh seedlings that have grown from the field have at least more than 30% more than in the past. The green vegetable seedlings in the field are also shiny and shiny, and they grow very well.

The pigs and sheep fed by some people have grown much faster than in the past, and they are unsightly fat.

The fat is ugly, but the heart is cool and crooked.

Even the seeds of Yaopu planted on the mountain of Luyunnan were the first to sprout.

Since Lu Yun handed over the work of movable type printing to Li'er, he has only seen Li'er drilling in the mountains and fields every day.

Lu Yun's idea was provided, but the right raw materials, workers, and craftsmen who copied the calligraphy were all long-term projects. It's not just the mud in the field that works well.

Li'er is rarely in the territory, most of them are in the mountains, looking hard, but he is happy, and he is full of fighting spirit all day long.

Several times, he walked out of the village in a daze, and he didn't know where to find a lot of workers, all of whom were familiar and skillful, and the wages were cheap.

I heard two hundred miles, I'm afraid that all the skilled craftsmen have been found?

One night.

Lier is supervising the work, and the movable type printing has reached the most critical steps, and there are not many engraving molds left.

He was pondering what to do when his eyebrows suddenly jumped.

Then hurriedly threw down the lantern and ran up the hill.

In the middle of the night, there was a direct knock on the door of Lu Yun's courtyard.

Squeezed in, took off the cloak, and said in a low and panicked voice: "Have you ever offended Lian Yunzong, a person named Li Suoying?"

"Yes! That Li Yishan is Li Ying's father. Everyone in the territory knows about it. You're in the middle of the night, why are you asking this?, could it be that he's going to come and discipline me?" Lu Yun yawned.

What should come will come, and there will be no escape.

"My lord, it's not that simple. ”

"That Li Soying is an official disciple of the Lianyun Sect, and at this time, he is fighting with the people of the Poison Sect in the Lianyun Mountain Range, three hundred miles away. There is a posture of defeat and escape. Riel explained.

"Isn't that it? I can't say that he was killed by the people of the Poison Sect, and it also relieved my hatred. Lu Yun was puzzled.

"Where is it so simple, my lord, three thousand years ago, there was a tragic battle in the Dusk Cloud Cultivation Immortal Realm, so the country was divided into a territory. ”

"But outside of the Twilight Cloud Immortal Cultivation Realm, there are other Immortal Cultivation Realms and forces that swallow and plunder each other. is commonplace. ”

"This Poison Sect is not a force in my Dusk Cloud Cultivation Immortal Realm. Rather, he is a member of the Demon Dao Alliance. ”

"Li should be a labyrinth six stars! ”

"There are regulations in the Dusk Cloud Immortal Cultivation Realm, during the war period, the people in the Immortal Cultivation Realm have no enmity between life and death, and they must not kill mortals in vain, otherwise they will be severely punished. Then Li should not dare to do it directly to the adult. ”

"But he's going to cut off our entire Li Jiahe and bury his father with him!"

"Think about it, if the people of the Poison Sect released poison in our Li Jiahe in the process of chasing and killing Li Ying, then?"

"Shhh

Lu Yun instantly gasped.

What a borrowed knife to kill.
