For a Prosperous World

It was late, and the light in only one room in the field hut was still on. The white-shirted boy in the room sat down at the table with a pen and drew on a silk cloth.

It was time to finish the last stroke and he set aside his pen.

His eyes fell on the canvas in front of him, the painting was already beautiful, and the woman in the snowy night looked beautiful.

But the teenager looked dissatisfied when he looked at the painting, and took a sigh of relief, slowly rolling up the canvas.

It's still a bit of a mood, and he saw the original painting of the Shuo Fang girl that year, far from being comparable to this one he painted.

I thought it was only the difference between silk cloth and painting paper, but he has tried several times. Even if he painted with silk cloth, he couldn't draw that truthfully.

Shuo Fangnu's painter did not leave a name. I heard that this painting was his last work. After that, he never painted anything else, which is a pity.

"Papapa."

The rain hit the window and made a flapping sound. The air was cold and the rain outside had not stopped.

The teenager put the rolled canvas aside the table, sat at the table, and turned his head to look out the window.

The windows were hidden, and the rain outside was dark, and nothing could be seen, only the distance seemed to see the shadows of several distant mountains.

With a bit of coolness on a rainy night, the two sleeves were slightly cold.

The boy stood up and pushed the door open, and the sound of rain outside became more chaotic as the door was pushed open, and he shattered it in the courtyard, splashing a splash on the ground.

It was almost midnight, and the teenager turned his back and walked in the corridor beside the yard. He was going to visit the guest again, hoping it would be really harmless.

He didn't rest until that time and was worried that something would happen at night, and the cane in the guest's hand always gave him a bad feeling.

The boy's footsteps were not heavy at night and he was not heard by the rain. He walked to the guest room on the side of the courtyard.

The lights in that room had gone dark. The people inside had already rested, and the frown between the boy's frown was slightly loose. It seemed that he was really attentive.

It is also inevitable that he is so cautious. Now that there is no father and brother in the family, he is the elder brother. They all say that the elder brother is like a father and naturally he wants to keep his family safe.

It didn't take long for the Yellow Turban disaster to happen. Outside the bandits, a person of unknown origin may be living in his home with a sharp weapon.

I am afraid that ordinary people's homes will not let such people come in, and it is already his concern that they can stay overnight.

The teenager was about to leave, but suddenly found a bamboo box in front of the room.

It's the box the guest carried.

How the box was placed outside, a hint of doubt appeared in the boy's eyes, and he walked over.

The box was placed on the steps under the eaves, and there was no rain, but even then it should not be placed outside but in the house.

Standing in front of the box, the boy hesitated, and reached out to open the bamboo wooden box.

Looking at the contents of the box, even the often frivolous teenager swallowed a spit.

A whole box of books, which is even enough to fill a few small bookshelves.

In these days, books are a rare thing, and there are only so many books in his family, most of which are left over from his father.

It can be said that he has never seen so many books put together in his life.

The boy's mouth moved, and the hands holding the box shook.

He fixed his eyes on the book box, and looked at the titles above. He had never seen many titles, even unheard of.

This further exacerbates the temptation of this box of books for this young man.

I was stiff for a moment, and looked at the room, there was no sound in the room.

His face was red, with some shame in his eyes, and he wanted to close the bookcase, his hands stuck there again.

There is always an idea in my heart, just look at it and put it back after reading it.

In the end, I didn't hold back.

I took one out of the bookcase, carefully raised my clothes, was sitting beside the bookcase, and looked up.

Look at it first. After reading it, ask the gentleman in the room tomorrow for punishment.

The sky slightly opened, revealing some moonlight, shining on the young man kneeling beside the book box, and slightly lighting the book in his hand, so that he could see the writing on it.

The book he held in his hand was called the Mathematical Brief.

When he first saw it, his brows frowned slightly. The arithmetic on it was a form he had never seen before, with many symbols he didn't even know.

But as he understood it, he soon became immersed in it, his eyes became brighter and he lowered his head from time to time.

Although the arithmetic method in this book is special, it is extremely convenient and simple, and the calculation in the book is much faster than conventional arithmetic.

If the popularization of arithmetic on it is enough to change the ancient arithmetic system, only a thin book is enough to say that it is an arithmetic work.

The theory of math is not too thick. It is only two hours after the teenager has finished watching it, and the sky is still dark.

He closed the book, and looked intently at the book box again, with an inexplicable look in his eyes.

This is just one book. If there are such books in this box ...

The bookcase at this time was a treasure in his eyes.

But then there was a sudden regret in my heart.

The guest in that room will probably leave tomorrow, and I am afraid I can't read a few of the boxes of books by myself.

Looking up at the sky, there are probably a few hours when the sky is about to light up, and the teenager puts the math in his hand back into the bookcase.

He is preparing to pick up the following introduction to arithmetic, which in his opinion should be a further explanation of arithmetic.

However, his hand stopped again, instead of going to the introductory book of mathematics, he picked up the Bingjia General Theory.

The night is too short, he can only choose to watch more. His calculations are not good, and this is a kind of content that he has not learned at all. It is the same as learning from scratch It's a book of numeracy, but he read two hours, not to mention more in-depth content.

It ’s better to look at something easier to understand first.

General theory of Bingjia, the title of Guan Zhi should be a Bingshu.

Holding the book, the teenager turned a page.

It is indeed a book of soldiers. He did not read the theory of soldiers at all before, and even read the book of soldiers' grandsons.

But he still sighed about this general theory of military art, which contains several unique strategies for using soldiers, but each has its own practicality. The text is simple and not blind, so people can quickly understand what it means.

For example, he was very impressed by a sentence in the book that summarized guerrilla tactics.

It is sixteen words. The enemy advances and retreats, the enemy stays with me, the enemy is tired, and the enemy retreats.

Time passed quickly, and the boy sat by the bookcase and watched all night, until the next day the sky lit.
