Although the Mid-Autumn Festival court dinner came to an end, the interest of this emperor in the palace was not very high.

The reason is very simple, that is, not only did he lose face, but he also got the answer to the question, which also did not make this emperor's heart heavy.

"Maybe that's a good idea."

Seeing Lizhi pestering her mother with a happy face, even Li Shimin's face showed a gentle look.

However, Yafu told Wujian about Haiyan, and even Li Shimin paid attention to it.

After all, no matter before or now, salt is a big thing, even Li Shimin knows that this matter must not be leaked.

"Looks like I'm going to Shufu."

Li Shimin muttered softly, and there was no dissatisfaction in his words because he was slapped in the face by his father.

Obviously, it is not once or twice that he has been hit by his father, on the contrary, it is still more important to have interests.

As for face, maybe Li Shimin would have cared about it before, but after letting go of the first time, then there will naturally be a second time.

.........

The next day, unexpectedly, the news of last night's Mid-Autumn Festival court dinner spread.

An Xuangong's appearance after two years, his demeanor still makes many people want to worship.

"What a poignant poem."

"If you didn't know that this topic was specially prepared by Your Majesty, I would have thought that An Xuangong had been preparing for a long time."

"I have long known that An Xuangong is a Wenqu star, and his current words confirm this."

.......

There was another commotion in Chang'an, which reminded people of the existence of this sage.

If it was Shu An in the past, he might have used the topic to play a wave, but now, Shu An doesn't have this mind.

He has everything he should have, and now it's not bad, and there are no new tasks in the system.

Shu An also didn't care, he didn't rely on the system to get to where he is today, but more because of the knowledge of later generations.

In terms of the system, it can be regarded as a surprise for him, of course, Shu An still has some thanks to the system.

Because if it weren't for the system, then maybe he would become a gentleman, and maybe he would be nostalgic for the land of smoke and willows.

People's desires are endless, especially after coming to this era, even the identity of Shu'an, who has just crossed over, is better than ninety percent of the people in the world at the beginning.

As long as you are not in Chang'an, if you change places, it is not difficult to live a drunken life.

Even if the world changes in the future, he can still escape by hiding in the mountains in the countryside.

It can be said that Shu An did not have such an idea at the beginning, but thanks to this system.

Although the system has restricted him a lot, Shu An doesn't have much resentment, although he has lost a lot, he has also gained a lot.

Shu Mansion was not angry for a long time, until Shu An returned, but fortunately, someone was taking care of it every day.

But today, Shu An showed a look of interest on his face, because Li Shimin's figure had already appeared here.

It can be said that such a scene has been seen for a long time, and of course, Su Dashan, who was waiting on the side, was also the first time to see this emperor so closely.

The excitement is naturally there, but Su Dashan can barely suppress it, after all, it is not the first time.

Of course, Su Dashan also knew that if he could meet this His Majesty, at least he would be familiar, then it would be a great opportunity.

Whether he enters the career in the future or continues his current identity, it plays an important role.

No one in the world can escape the word fame and fortune, even Shu An is no exception, even if he is retired now.

But if he loses the fame he accumulated before, even Shu An can't accept it, and as for Su Dashan, he is also accumulating his own prestige.

Compared with when he first came to Chang'an, Su Dashan can be said to have a lot of prestige, even in Chang'an, he still has a lot of fame.

It's a pity that this prestige is still not enough in front of this An Xuangong.

Su Dashan's thoughts were not known to Shu An and the others at this time, although he had not caught up with this emperor on such an occasion for a long time.

But the two are like a pair of friends, and it can be said that they started talking from all sides.

Perhaps the best thing you know is your enemy, even if the two are not enemies, but for a certain period of time, the two are still enemies.

Naturally, mutual understanding is not small, especially Li Shimin, every time he chats with this father, he has gained a lot.

So this time, Li Shimin deliberately came to Shu Mansion after the court meeting, and many things were postponed.

Just to discuss it with this father, it seems that there is no difficulty in his difficult problems with the father.

But there is an end to the words, so it is also time to get to the point, Li Shimin is here for salt.

It is important to know that due to the impact of the war, many salt mines have been destroyed, and there has been no mining for many years, and the whole world is very short of salt.

"I have a little bit of salt here, but it comes from the sea."

Shu An's eyes seemed to be smiling, and he said with a smile, the fact that the matter of Shanghai salt manufacturing was recorded a long time ago.

It was even postponed to antiquity, but there is also a reason why it was not popularized.

On the one hand, it is because salt in this era needs to be refined, which consumes a lot of firewood and labor.

On the other hand, the government collects salt taxes, and as for the current period, it can be regarded as a special period.

In the third year of the emperor's reign, Yang Jian began to change the law, that is, private individuals could also sell salt, and the salt tax was abolished.

At the beginning, he didn't know Yang Jian's considerations, but in this era, salt is indeed an important item, and the salt tax is also a big one.

There are various reasons that have led to the current situation, and if sea salt is not handled well, it is still poisonous, especially in this era, there is not so much chemical knowledge.

If there is no unified and standardized method, then the salt produced is even more problematic.

This also leads to the fact that if there is a choice, most people will not choose sea salt.

For many reasons, the main sources of salt brine are still some inland salt lakes and the like, also known as salt mines.

In fact, Shu An doesn't know the problem of purification, but it is a coincidence, because he was born on the coast in his previous life, so he knows a lot about Haiyan.

Knowing the steps, at least the technology for making salt can be said to be hundreds of years ahead of the current one.

"Sea salt?!"

Li Shimin's eyes showed a hint of thought, and he muttered softly, he couldn't wait when he heard the emperor of salt before, but he didn't pay too much attention to it.

However, as an emperor, he also has an understanding of salt brine, and he also knows the disadvantages of sea salt.

Wait, it is impossible for the Father not to know about this question.
