The prices of large mines are high, and grain cannot be grown in the mountains, so the prices are still expensive.

Small mines are enough, therefore, these large mines, on the contrary, are idle and no one buys them.

Hearing this, Li Su couldn't help laughing and said, "Okay, His Royal Highness has bought all three of these mountains!" Do the math, how much does it cost? ”

Lao Yi hurriedly said: "Your Highness, what about these three mountains, this place is not small, a total of one, one hundred and eighty-six runs, this-"

Li Su said directly and happily: "This king will give you 1,200 yuan, and I will handle the contract for this king immediately." ”

"Okay, Your Highness, wait a minute, it'll be right away!"

This time, Lao Yi didn't dare to be too ruthless.

Lao Yi can probably figure out a little bit of Li Su's dog temper now, what is rewarded to you is what is given to you, but if you use deception, it is estimated that the end will be very miserable.

Soon, Lao Yi completed the transfer procedures for the contracts of the three mountains and handed them over to Li Su.

As for money, Lao Yi is not afraid at all.

After the formalities were completed, Li Su took Xiao Liuzi and left, and someone would naturally send the money.

Now the largest saltpeter mine near Chang'an City is all in his own hands, so it will be easy to do.

Li Su ordered someone to call Qin Huaiyu and decided to hand over the mining of saltpeter ore to Qin Huaiyu.

Because next year, he will go to the fiefdom.

And his brother Li Ke will definitely leave.

Therefore, now simply leave it to Qin Huaiyu to mine.

Even if he goes to the fiefdom, this business can be handed over to Qin Huaiyu to do.

After calling Qin Huaiyu over, Li Su said to Qin Huaiyu: "Huaiyu, I bought a few saltpeter mountains, so you can help me mine saltpeter this year." By next year, these mines will all be yours. ”

Hearing Li Su's words, Qin Huaiyu immediately said, "Your Highness, this is absolutely not good!" I can help you, but I won't want your mine. If you treat me as a brother, don't say anything like that again. ”

Li Su smiled slightly: "Huaiyu, listen to me, wait for next year, I will go to the fiefdom." I'm not here, what's the use of keeping the mine? ”

"What? You're going to the fiefdom tomorrow? How can it be so fast? Where's your fiefdom? Far from Chang'an City? ”

Li Su smiled and said, "The fiefdom has not been decided yet. Don't worry, wait until next year to leave, besides, it's not like you won't see each other in the future, okay, that's it! ”

Hearing that His Royal Highness was going to the fiefdom next year, Qin Huaiyu was very sad in his heart, and he didn't argue with Li Su about the mine anymore.

However, Qin Huaiyu had already made up his mind in his heart, even if His Highness left next year, this mine would still be his, but he would definitely help him take care of this mine.

Although the Qin family had not mined saltpeter ore before, there was no shortage of manpower in their family.

Soon the Qin family organized a group of people to go to the mountains to mine saltpeter mines.

It is believed that it will not be long before the first batch of saltpeter will be delivered.

……

At this time, a major event occurred in Datang that caused a sensation throughout the country.

In almost all towns and cities, cheap books began to be sold.

These books are all books for exams, or annotated editions.

The price of this kind of book is only 100 yuan.

This situation has caused a sensation in countless places.

When I got the news, I went crazy and bought like crazy.

Some people even buy dozens or hundreds of copies at once.

They themselves are crazy, but they think that the people who sell books are crazy and sell books at such a cheap price.

Eventually, however, the purchaser found that the bookstore had so many books in stock that he couldn't buy them all.

In other words, the more books he buys, there is no room for appreciation at all.

Although I don't know why, the price of books has dropped more than a hundredfold all at once.

But in the current situation, it is clear that books have lost room for appreciation.

As a result, those who buy more have to lower the price and sell again.

Such a situation directly led to the complete flood of books in Datang.

Even those who are poor and can't afford to buy books don't have to worry about not being able to borrow books.

Because there are so many books.

This time, the situation of no books to read was finally broken.

Moreover, there is no need to ask someone for advice when reading sentences.

Because these books have already broken the sentences with punctuation.

It's just that if you encounter a word you don't know, or a place you don't understand its meaning, there's no way to do it.

These places can only be guided by famous teachers.

However, with these books, the opportunities for those poor children have also increased greatly.

At the very least, they can have books and can read and memorize them all day long.

I only know that when I meet a famous teacher, with a little dialing, my memory can be more solid.

And these books, although they are actually made by Li Su.

But on the bright side, it's all those families who are selling.

Therefore, on the contrary, it has made the family earn a wave of prestige among the people.

Of course, as for what they think in their hearts, they can only be described as bitter in the baby's heart, but the baby doesn't say it.

……

A few days later, a small amount of saltpeter had already been sent to King Liang's mansion, although the amount was still a little small, but it was definitely enough for King Liang for the time being.

At the same time, Yuan Tiangang from Netzhou, wearing a pair of cloth shoes with exposed toes, walked into Chang'an City in the dust.

When entering the city, Yuan Tiangang looked at the sky above Chang'an City, didn't know what he saw, and frowned tightly.

After entering Chang'an City, when he finished washing and changed into new clothes, he was summoned into the palace.

Jiucheng Palace, in the Hall of Xiande, Yuan Tiangang bowed and said: "The ministers see the emperor!" ”

Seeing that although Yuan Tiangang's face was full of wind and dust, he had the bearing of a fairy wind and bones that did not eat the fireworks of the world, which made Li Shimin feel a little convinced.

Li Shimin couldn't help but ask Yuan Tiangang: "In the Han Dynasty, there was a Yan Junping, who was a master of mathematics, and I now have Aiqing. I don't know how Aiqing compares to Yan Junping? ”

Yuan Tiangang couldn't help but say: "Your Majesty, Yan Jun's life is not at the right time. And Wei Chen was fortunate to see the Son of Heaven, so the minister's luck was much stronger than him. ”

Hearing Yuan Tiangang's words, Li Shimin couldn't help laughing.

Li Shimin couldn't help but ask: "Then Aiqing divides a hexagram for my Tang Dynasty fortune, how about my Tang Dynasty fortune?" ”

In fact, as early as when he was in Wangzhou, Yuan Tiangang had a divination.

It's just that the hexagram is not very good.

Because Yuan Tiangang calculated that after Li Shimin, the Tang Dynasty would have an empress!

And this empress will massacre the royal bloodline.

But this kind of hexagram, Yuan Tiangang didn't know how to remind Li Shimin.

If you tell the truth, I am afraid that it will lead to a river of blood and involve countless innocents.

These sins will eventually be counted on his head.

But now, since Li Shimin asked him to divination, he had to divinate again.
