The emperor who returned to the palace couldn't help but show a tired look on his face.

Although he received a new method of salt production from his father, it was clear that the emperor was still troubled by what his father had said.

"If I deal with it in the future, then I don't know how much trouble it will bring to Datang, and I can't leave this matter behind me and treat it as if I don't know."

Li Shimin's eyes flickered and he muttered softly, this emperor, who is still young now, couldn't help but show a resolute look on his face at this time.

It's a pity that the rice has to be eaten in one bite, and it is not so easy to solve this problem.

First of all, he still sold sea salt, and then competed with those families, and even Li Shimin wanted to deter these families.

Tell these people that the current Datang is my Datang, not the pure land of the family.

........

Li Shimin's plans in the court Shu An was not clear, because Shu An was accompanied by Wu Shun at this time.

It appeared in the Chang'an teahouse, and when he returned to Chang'an for a week, Shu An simply took a look in Chang'an.

"It's been a few years since the last time I looked at Chang'an like this."

Shu An thought silently, it was already when he had just returned to Chang'an.

Compared with the current Chang'an, it is undoubtedly much more lively, and the traces of gunpowder smoke in the past have gradually precipitated.

"Master, there are a lot of new things coming out of Chang'an now."

Laifu said with a smile on his face, because in the past, he used to sit in a restaurant or a certain high place with the master.

I have seen the scenery of the mountains and rivers of the Tang Dynasty, but after returning to Chang'an, there are fewer such things, but this does not hinder the memories of Laifu.

"Something new?"

Shu An's eyes seemed to fall on the crowd passing on the distant street, and he whispered softly.

After he returned to Chang'an, it can be said that he launched a lot of things, such as chairs and tables.

Coupled with the fact that the heavens and the earth use fur to wrap them, these people have begun to draw inferences.

And after the cotton came out, some people had a new idea, and directly filled the cotton with fur to make something called a soft chair.

Of course, in Shu An's eyes, this is the original shape of the sofa in later generations, although it is not comparable, but the price is very expensive in this era.

However, it is deeply loved by the second generation of those nobles, in addition to the changes in the table and chairs, there are also changes in tea.

Among them, Shu'an has also launched a lot of tea, which also inspired some people, and there is no patent in this era.

It is also inevitable that the method of roasting tea will be exposed, and some people will also try a variety of tea configurations.

There are some people who have succeeded, but they have attracted the attention of many people, all in all, even if they have no intention of changing.

But Datang will also be indirectly affected by him, of course, Shu An doesn't care about this matter.

Because don't underestimate the wisdom of the ancients, even if there are still many ancient mysteries that later generations do not understand, they are only limited by their horizons.

"Hey, who's those guys?"

But at this moment, Shu An's eyes fell on the street, a few people in strange costumes.

Some of the costumes were familiar to him, but he asked about blessings instead.

After all, if anyone is more well-informed in Chang'an, then it must be a blessing.

"Master, that was the envoy from Fusang to Tang before, and it is said that he came from a small country called Yamato."

"And the messenger sent by Silla, and this one is the messenger of Linyi."

"Among them, the envoy of Linyi brought a lot of tribute, which is said to make His Majesty very happy."

"I don't know what caused these people to get together."

........

Laifu's face showed a hint of interest and talked about this matter, being in Chang'an, even if Laifu heard and saw it, he naturally heard a lot of things.

In addition, because the old man also let himself collect information, naturally Laifu is still concerned about this matter, although he doesn't understand what these small surrounding countries are doing when they come to Datang.

"Send Tang envoys?"

However, hearing Laifu's words, Shu An's eyes showed a glimmer of light, and he thought silently.

It seems that around this year, many small neighboring countries began to acquiesce to the status of the Tang Dynasty's suzerainty.

This period of history has just defeated Jieli, which can be regarded as causing a lot of shock.

And now, it is not only as simple as defeating Jieli, but also annexing the whole of Annam.

Among them, the strength shown by Datang can be said to be far better than that of the same period in history, and some of the surrounding small countries have not changed much.

Similar to Fuso, now is the era of the Yamato royal power, and people are sent to Chang'an to learn.

As for Silla, then it was to seek support, and the reason for this was that Silla's position was a little awkward, with Goguryeo in the north and Baekje in the west.

The last Linyi is much more interesting, because this small country is in the Indochina Peninsula, that is, in the direction of Annam to the south.

Unfortunately, after the Tang Dynasty annexed Annan, this small country began to contact head-on.

How can this not make King Linyi panic, so it is understandable to send people, perhaps because the end of the world has fallen at the same time.

So the envoys of these three small countries got together, and after thinking of this, Shu An's eyebrows couldn't help but raise slightly.

"There are some things that I can't help but do."

If he hadn't met these people, Shu An might not have cared about this matter.

But when encountering words, then naturally Shu An can't watch these small countries rise, especially a certain country in later generations, which makes him have a natural disgust.

Naturally, these people can't be allowed to bring back the advanced technology and culture of Datang, he is not like Li Shimin, who thinks it's not a big deal.

"By the way, master, Feng Zhuguo seems to be arriving in Chang'an."

Just as Shu An's thoughts were flying, Laifu seemed to remember something again and continued to speak.

"Is Feng Ang here too?"

Shu An's face was slightly stunned, but he quickly said softly.

How to say that Feng Ang is not an ordinary person, and he had a close relationship with Feng Ang before whether it was grain or sugar.

In other words, it can be regarded as mutual benefit, Lingnan is barren and needs money, and Shu'an needs materials.

Anyway, the previous events made Shu An have a good impression of Feng An, this is a person who knows how to advance and retreat.

Of course, Feng Ang is naturally a capable person, otherwise it would be impossible to sit firmly in Lingnan.

After thinking for a while, Shu An knew that he was afraid that he was going to meet this Feng An.

"If Feng Ang enters Chang'an, then send people to pay attention to his actions."

In the end, Shu An still commanded, obviously paying some attention to Feng An.
