Five thousand men, lightly armed, with the roar of horses' hooves, rode in the direction of Fengzhou, and suddenly, the Tuli Khan saw that not far in front of the direction of the army, there was a row of black shadows standing under the moonlight.

Behind the dark shadows, there were countless silent figures densely packed.

It is black and oppressive, and it looks extremely terrifying on the grassland.

"Who's up ahead?"

"Khan, my subordinates don't know."

"Detective!"

The people in front were naturally Li Jing's 50,000 army, and Li Jing, who was at a loss, changed his strategy according to Ma Shixiang's thinking, no longer in a hurry to march, but fought steadily and steadily, and went all the way to investigate all the way.

After all, 50,000 people are not a small number, and once the formation is completely opened and cut off by someone, it will be a dead end.

Suddenly, he heard footsteps, horses' hooves, and whistling.

The wolves of the steppe had long since taken refuge, trying to escape the cold of winter in a cave with what little warmth was left.

At this time, he was disturbed by the sound of horses' hooves, and in an instant he poked his head out and let out a howl.

Under the full moon, Li Jing suddenly smiled.

"God help me! Looks like a big fish! ”

At this time, Ma Shixiang suddenly exclaimed, "General, the clothes and banner of the leader are like the Turkic Turkic Khan!" ”

The killing on the grassland was carried out silently under the moonlight, and there was no peace in Chang'an City.

Li Hui came to Hechen tonight, in the huge courtyard, it was extremely luxurious, and it looked like a rich man's house.

And the shopkeeper is not there, and He Chen can almost be called a little bully at home.

"I never thought that you would make salt here, I thought you would be in Longyou."

Li Hui sighed, "Although your family is big, it is not a long-term method after all. ”

"Li Hui, didn't you say it, this salt-making Datang is in control, and I'm waiting for Datang to do business with me and Chen."

"Don't say it, as soon as our salt comes out, the people of Chang'an are crazy to grab it, and they don't earn much, and it will be less than two pennies, but there are many people in Chang'an."

"That's right! Salt is a must-have. Li Hui nodded, "Vinegar cloth or something, it's too disgusting, isn't the salt of Baihuahua bad?" ”

"Li Hui, when you go back in a while, remember to bring these silvers."

"It's not much this time, it's only 150,000 taels."

Li Hui suddenly found that his current money was a bit inexhaustible.

"Hechen, are you interested in making a bookstore?"

He Chen was still melancholy, but when he suddenly heard Li Hui's idea, he immediately jumped up, and the wine in the wine glass in his hand spilled out.

"Yes, yes, why not!"

"No, what do you say? Publishing house? ”

He Chen hesitated, "Li Hui, do you know what Datang's bookstore is like now?" ”

Li Hui didn't know much about this, "Isn't it profitable?" ”

He Chen pouted, "It's not just that it's not making money, it's all about sticking money!" ”

"If it weren't for the huge number of books purchased by the Ministry of Household Affairs every year, those bookstores would have lost out long ago."

Li Hui didn't expect this, "Why doesn't the bookstore make money?" ”

"Hey, when printing, you need to engrave it into a board, engraving printing do you know no, a wrong word, the whole engraving will be wasted."

"All bookstores in the world are printing the Four Books and the Five Classics, some commonly used books, and books that are out of the door, and they are engraved

After that, if you use it once or twice and throw it away, how can you make money. ”

"Besides, paper is also expensive, we pay attention to profit in business, and if we can't make money, I will definitely not do it."

Li Hui understands that this product is interested in making money now, as for what to do with making money, and how to continue to develop after making money, he doesn't want to think about it at all.

The fun of Hechen lies in the process of making money.

If you don't make money, you don't have interest.

Also, this young man, who has been clothed and fed since he was a child, has no shortage of food and clothing, and he has long been used to it.

Money may really be a number to him.

He Chen smiled smartly, "If Li Hui you have to open a bookstore, then I will reluctantly follow you, after all, I have also made a lot of money with you, and it is nothing to lose so much occasionally." ”

"We are friends, I am a person, making friends never depends on whether he has money or not, anyway, I don't have money."

Li Hui twitched twice on his face and laughed at the moonlight, "Hehe, this sentence is interesting." ”

Li Hui now has a feeling that this Hechen's family background may be far more than a grain merchant, and it is not even as simple as following the nobles in the palace.

Perhaps, there is really nothing wrong with what He Chen said.

"The key point of the bookstore is two things." Li Hui stood up and said slowly, "The first thing is paper, Datang's papermaking skills are not very good, the cost is still relatively high, ordinary readers use a lot of paper, and they can't afford rice paper, so they can only use straw paper, which shows that the price of paper is very high." ”

When He Chen heard this, he nodded again and again, "That's not it, when I was a child, I used to take out some money to buy rice paper from my own money, my father was extremely strict with me, hey, at that time, in order to buy rice paper, I don't know how many times I missed the opportunity to have a night of spring dinner with the Drunken Moon Lou Oiran." ”

Li Hui ignored him and continued: "The second is the art of printing, the cost is extremely high, and if you are not careful, a few taels of silver will go out. ”

The cost of engraving printing in the Tang Dynasty is not low, similar to rubbing, but it is one big one, one page and one edition.

The effort required is extremely high, and the formation of each engraving plate requires at least one or two pieces of silver.

How many + pages is a book, and the cost is at least a few dozen taels, how much is a book?

One tael more, twenty dollars less.

Only by selling more can we earn back the cost.

At this time, Li Hui thought of a good way, since there is no mechanical printing in later generations, so why not try movable type printing?

"If these two key points are solved, do you think we can make money?"

He Chen sneered, "How is it possible, Li Hui, so many Confucians have not been solved, can you?" ”

This is the first time that He Chen has questioned Li Hui, not that he does not believe Li Hui, but that the limitations of this era limit He Chen's imagination.

"Hehe, Hechen, how many words are there in our Datang text?"

"I don't know, it's not many anyway, it's only a few thousand."

"That's right, we carve out these words separately to form small seals, and then create a mold, what needs to be used, inlaid in it, and then directly rubbed out like engraving printing."

"Huh?" He Chen's eyes lit up.

He never thought that printing could still come like this?

"This ...... Li Hui, you are such a genius! ”

All night, Li Hui was instilling in Hechen the advantages of movable type printing, low cost, convenient, and the most important thing is that no matter what kind of book it is, others dare not print it, they dare!

In this way, there are many kinds of books, and naturally there are countless customers who come.

Folk cultural enlightenment may begin at this time.
