Fang Yizhi really didn't know much about the supply of salt in the Tang Dynasty, so after returning home, he immediately went to see his father, relayed Li Yuanjia's words, and then frowned and said, "Father, what do you say...... The king, he doesn't want to meddle in the salt industry, does he? ”

"Meddling? How did he meddle? ”

Putting down the book in his hand, Fang Xuanling glanced at his eldest son and asked lightly.

"Uh......"

After being stunned for a moment, Fang Yizhi said a little dazedly: "This kid doesn't know, I just heard the king say that he wants to find a place to try...... It's just that he didn't elaborate, so on the way back, the child had a guess, did he want people to make salt? ”

"Salt making? Hehe, is salt making such a simple thing? ”

Squinting his eyes slightly, Fang Xuanling smiled lightly and shook his head.

Fang Xuanling is still young, and he doesn't know how troublesome this salt making is, but Fang Xuanling has been the prime minister for so many years, and he understands the Tao of this very well. Whether it is inland well salt or salt taken from the sea, it is nothing more than a boiled word. For example, boiling salt in seawater is actually boiling seawater dry, and what you get is coarse salt with an astringent taste.

It's easy to say, but it's a hassle to do.

How easy is it to boil a big pot of seawater? The salt workers generally use large clay pots, and they also use cut wood, and the amount of wood consumed by boiling and drying the sea water every day is a huge number!

All the costs add up, and that's pretty staggering.

In the past two years, because of the inspiration of Li Yuanjia to stir-fry in an iron pot, some people thought of using an iron pot to cook salt, and the efficiency has been greatly improved, but the corrosion of seawater on the iron pot is too great, because it has to be replaced with a new pot every few days, which is really distressing!

And don't forget, it's just boiling salt.

Even if you boil the salt and want to sell it, you still have to be able to transport it to the states of Datang, and you have to open stores in various states and counties, or find stores that are willing to sell your salt......

Think about it, what a huge project this is?

Datang is so big, it takes months to walk from south to north once, where is it so easy to transport? Where is it so easy to get into those salt trafficking networks that have been woven for a long time?

It's really not that Fang Xuanling looks down on Li Yuanjia, but he really can't believe that an idle king can do such a thing!

Of course, with his power as the Prince of the Tang Dynasty, it is not impossible if King Han really makes up his mind and is willing to spend more than ten years and invest a huge amount of energy to do it, but what does that mean to him?

Just to make money?

Not to mention Fang Xuanling's understanding of Li Yuanjia, the other party is not a reckless person, and the low-key of these years has fully illustrated one point, that is, his son-in-law is a young and mature stable character, and it is impossible not to see the crisis that his meddling in salt production will bring!

Up to the emperor, there are those families who control the salt industry, and below there are people who make a living by making and selling salt, who wants to see him rashly break in?

Although the benefits in this are indeed very large, Fang Xuanling doesn't believe that Li Yuanjia will not understand the consequences of offending these people, especially the one who lives in Daxing Palace, is really willing to see his younger brother meddling in the salt industry?

So for his eldest son's worries, Fang Xuanling naturally scoffed and didn't care.

Merely......

Although Fang Xuanling didn't care at all, he would think of Li Yuanjia's eyes and expressions at that time, Fang Yizhi was always a little restless in his heart, and couldn't help but say: "Father, I always feel that this time the king is not joking, maybe he really wants to meddle in!" And I think since he has this idea, he must have a certain certainty! Father, don't forget, since Han Wangfu can make a Quyuan plow and make 300 overturns a month, maybe ...... Maybe ......"

"Huh?"

Fang Xuanling couldn't help but be stunned after hearing his words, and then his eyes were solemn, and his expression became solemn......

……

"Hehe, it's done!"

Taking a deep breath, Li Yuanjia finally made up his mind!

Isn't it just a seawater salt drying method?

Not to mention anything else, just for the sake of the ancestors who have suffered for thousands of years behind us, there is no reason for Li Yuanjia to think that he does not know the existence of this technology.

In any case, salting in seawater must be taken out.

Li Yuanjia didn't want to become a great sage, and he didn't want to take the benefits of seawater salt in his pocket...... He also doesn't have the ability to withstand the counterattack of those stakeholders. But he believes in one thing, that is, if he wants to come up with this technology, Zhenguan Times is definitely the best choice!

Because the master of this era is the Tang Emperor Li Shimin.

Maybe in the middle and late Tang Dynasty, the emperor didn't dare to touch the interests of those wealthy families, but in this thriving early Tang Dynasty, what did Li Shimin dare not do?

At least if the benefits are enough, move those cheeses in the salt industry, Li Yuanjia believes that his second brother will definitely not hesitate!

So the only question is whether you can get the technology of drying salt in seawater?

Is it difficult to dry salt in seawater?

Of course it's not that hard!

Although the Chinese did not begin to use this technology until the Ming Dynasty, in Li Yuanjia's view, if he really made up his mind to do it, it was nothing more than a question of how much time it would take.

The real key lies in the impact of the birth of salt!

In the Ming and Qing dynasties, it was already possible to use seawater to dry salt, but was it cheaper for ordinary people to eat salt?

No, because the imperial court needed salt to earn a lot of taxes!

Therefore, even in the Ming and Qing dynasties, especially in the Qing Dynasty, the cost of salt was greatly reduced, but when it came to the hands of the common people, it was still extremely high.

Because of the salt monopoly, because of the high salt tax!

So you can imagine how much benefit there is in a salt word!

In the early Tang Dynasty, although there was no salt monopoly, the cost of salt production was very high, and in the middle and late Tang Dynasty, in order to make up for the deficit of the imperial court, the salt monopoly was launched again, so that the salt tax once again became the revenue pillar of the imperial court......

Li Yuanjia's goal is to make seawater salt appear hundreds of years in advance, and try to change the history of salt eating for the Chinese people!

Merely......

"Ahem, don't be impulsive, don't be impulsive!"

After making up his mind, Li Yuanjia continued to warn himself: "It is absolutely possible to dry salt in seawater, but it must be done through the second child, and this must not be done nonsense!" And before telling the second child, it is best to be able to get the basic technology and process instructions right, and then go directly to the big project, and sweep the boiling salt into the garbage heap of history......"
