Li Yuanjia really didn't expect that the emperor would not want the technology of drying salt.

You know, that's salt!

However, it was precisely because of Li Shimin's refusal that he saw the mind of this Tang Taizong - once the salt drying technology is attributed to the emperor or the royal family, who dares to guarantee that they will not use all kinds of means to dominate the salt industry in the world for the huge interests here? When the time comes, if you are a little greedy, you will directly skyrocket the price of salt several times, and it will be the ordinary people in the world who are miserable.

Even if Li Shimin can't, can he guarantee that his son won't?

So this is not only a matter of mind, but also illustrates Li Shimin's long-term consideration, that is, the idea of taking precautions!

In other words, Li Shimin doesn't want the people to eat high-priced salt, and hopes that the price of salt will always be so low.

But for Li Yuanjia, it is one thing to let him dedicate the method of drying salt and purification to the emperor, and it is another thing to give it to others for nothing.

There is no way to give it to the emperor, he is a prince who must not touch salt, at most it is a few thousand catties a year to try; Therefore, if you want to make the salt drying technology appear in the Tang Dynasty, there is only one way to dedicate it to the emperor.

But the emperor didn't want it, and Li Yuanjia was reluctant to give it to others in vain.

And after listening to his sentence "can't be given for nothing", Li Shimin also twitched the corners of his mouth, and scolded with a smile: "Hehe, I didn't say that you should give it for free, who wants them to pay for it...... How much are you going to sell it for? 10,000 or 20,000? Or...... More? ”

When these two figures were spoken, Li Shimin was still faintly heartbroken.

Although he still has some difficulty believing his brother's words, he always feels that this method of drying salt is too exaggerated, how can a few people casually dry thousands of catties of salt in a year? However, the method of purification, the emperor felt that there was no problem, after all, the capital was there, and this kid had no reason to lie.

Therefore, in Li Shimin's eyes, the real value is the method of drying salt.

Even if it is not as powerful as Li Yuanjia said, as long as it is more efficient and lower than the current cost, it is enough for those salt merchants to come up with tens of thousands of dollars.

If I had agreed to Li Yuanjia's statement just now and included it in the inner treasury......

Shaking his head, Li Shimin quickly dispelled this dangerous thought. If he was willing to make this money, he would have started collecting salt taxes a long time ago, so why wait for this kid's salt drying method?

Datang is not short of salt!

As for the emperor's question, Li Yuanjia smiled intellectually, and then stretched out a finger.

"Ten thousand? Hehe, it's okay. ”

With a raised brow, Li Shimin nodded appreciatively.

This kid is not greedy!

He thought that Li Yuanjia would ask for more, after all, if it was really that easy to dry salt, the profit of that bucket of salt would be high. At most, the refined salt is sold to officials, wealthy merchants, and a small number of landlords, but the coarse salt is not known how many people in the world want to eat, and the amount is too large.

It's just that after shaking his head, Li Yuanjia's eyes suddenly narrowed: "No, it's not ten thousand!" Hehe, second brother, I'm going to sell it for a thousand yuan! ”

"Hmm...... Well? ”

first nodded reflexively, and then Li Shimin was stunned, and his eyes widened: "Eleven, what did you just say...... How much? ”

"Second brother, I said a thousand times!"

Blinking, Li Yuanjia replied very honestly.

"One, a thousand?"

His eyelids jumped a few times, and Li Shimin's eyes when he looked at his younger brother became more and more strange - this kid is really so generous? Or is it ...... Want to make a joke with me?

"Second brother, my brother didn't plan to sell it to one person!"

Seeing that the emperor's eyes were a little wrong, Li Yuanjia coughed dryly twice, and quickly explained: "I plan to write a book on the specific method of drying salt, and then publish it all over the world...... The kind that anyone can buy if they want to! ”

"Oh? That's a good idea! ”

After listening to his words, Li Shimin's eyes suddenly lit up, and he nodded subconsciously.

If you sell it to one person, you will get one benefit, but if you can sell it to countless people, then it will be countless people who can benefit from it, and the emperor still understands this simple truth.

It's just that after nodding, Li Shimin came back to his senses and asked suspiciously, "Huh?" That's not right! If anyone wants to learn, just go directly to those craftsmen in your house, why do you have to publish it all over the world? This is the ...... Wouldn't it be so easy to leak out? ”

"Hehe, then it depends on whether they can speak in such detail, and whether they are willing to wait."

Raising his eyebrows, Li Yuanjia said lightly.

Drying salt and drying salt is really to lead the sea water to the land, and the sun can shine on it? If it were so easy to talk too much, would this technology have come so late?

Hehe, how is that possible?!

Don't look at the people in Han Wangfu's mansion who got this technology not long after they went to the beach, but what is it based on? Who has the technical support provided by a prospective college student?

"Don't sell it, talk about it in detail!"

Under the urging of the emperor, Li Yuanjia patiently explained: "In fact, it is very simple, whoever wants to learn this art of drying salt must first buy a book, and then unify it to a certain place to learn it at a certain time...... Your Majesty, you can't just read a book, you have to go to the salt field to learn! ”

Speaking of these, Li Yuanjia couldn't help but think of those people at the beginning.

If they were to go to the beach on their own, God knows when they would be able to do it. It was precisely because Li Yuanjia took them to do many experiments before going that they had the miracle of success so quickly!

Can you read just by reading a book?

That's too easy!

"Uh......"

After listening to his explanation, Li Shimin suddenly realized, and scolded with a smile: "I said, I thought you were really kind, but I didn't expect it to be these doctrines...... But it's okay, a few more people can buy more people to dry salt, after all, there are still benefits. ”

"Second brother, I'm afraid there aren't a few more people!"

Blinking his eyes, Li Yuanjia smiled and said: "This salt merchant is the richest, if the younger brother can prove the benefits of drying salt, let alone a few people, I'm afraid there are more than dozens!" ”

“……”

After being stunned for a moment, Li Shimin rolled his eyes very rarely, completely speechless.

However, since he had already promised his younger brother, the emperor naturally wouldn't mind him earning a few thousand more yuan, so he just shook his head and asked, "Eleven, your purification method can also be used for other salts, right?" ”

"Hehe, of course you can!"

Nodding, Li Yuanjia said with a smile: "So the younger brother plans to print this method into a book, and anyone who wants it can buy it......"

"Alright, alright."

Looking at the smile on his face, Li Shimin had a headache, and hurriedly waved his hand and said, "Just do it yourself and don't need to tell me anymore." ”

"Yes, thank you, second brother."

After breathing a sigh of relief in his heart, Li Yuanjia showed a sincere smile on his face: "Then ...... Second brother, let's talk about glass......"
