"No problem." Huo Gang agreed very simply.

Although Huo Gang didn't know about the situation of his son, it might be serious, maybe it wasn't serious, but it wouldn't be more serious than Li Chengqian, Li Chengqian could return to normal, and Jinyang should have no problem.

He was confident in this, after all, Li Chengqian didn't even drink much concentrated spiritual spring water, and Jinyang was his sister-in-law, so she should be able to recover soon if she drank some concentrated spiritual spring water.

In fact, strictly speaking, Li Shimin's long life is good for Huo Gang, not to mention whether it will be Li Zhi or Li Chengqian who will take over in the future, no matter who it is, but Li Shimin's strategic vision is not comparable to yours.

To be precise, Li Shimin's magnanimity is not comparable to theirs, and the gap between the two is very large, as long as a little study of history can be known, but almost all the founding kings have a mind and bearing that ordinary people cannot match, and these two are actually very important in terms of national strategy.

Although Li Shimin is not the founding king, but in fact it is almost the same, Li Yuan was born before he became the emperor, and in the process of establishing the Tang Dynasty, Li Shimin has always led the army to fight, so he can be regarded as the founding king.

"Thank you." Li Shimin solemnly thanked Huo Gang.

Huo Gang smiled and waved his hand: "Let's not talk about this, it's my first time in Datang, and I don't know what this Chang'an City is like." Huo Gang changed the topic, he knew that if he accepted this thank you, Li Shimin's heart would be better, in fact, Li Shimin is a person who attaches more importance to feelings.

The emperor is not a fairy, but also has feelings, after coming to this world, Huo Gang found that in fact, those characters recorded in history have become vivid people, and only their exploits are often recorded in history, but in fact, they all have shortcomings, weaknesses, feelings, joys, sorrows, and historical records combined, you can find that they are living people.

It wasn't like the cold stereotypes that existed in his mind.

"Although Chang'an City is not as good as your Yumen Pass, it will not be too bad." Li Shimin immediately smiled and said.

"I believe that." Huo Gang smiled, after all, this is not only the capital of the Tang Dynasty, since the Qin Dynasty, this has been the capital of many dynasties, and so many dynasties have been continuously built, it cannot be too bad.

"By the way, you can also take a look, do you have any suggestions for Chang'an City?" Li Shimin said with a smile.

In fact, at this moment, the Chang'an City in the distance is already visible, because the city wall of more than ten meters high in this era is very tall! The Xi'an Huo Gang of later generations has been there, and as a very well-preserved Xi'an city wall, he has also seen it, but in the metropolis of later generations, the height of the city wall is actually nothing.

After all, there are more buildings than that, but in this era, looking at the majestic city wall from such a distance, you can actually feel its power, no wonder so many envoys from small countries came to Chang'an, and they were shocked by this city wall alone.

In this era, counting all the countries of the world, to be honest, there are not many cities that have built walls of this scale! Not to mention that the area is so huge! The city wall of Yumen Pass is actually more majestic than Chang'an City, but that's it, but the real majestic building in Yumen Pass is the National Assembly Hall.

The kind of architecture that came from later generations could not be built in this era.

The city wall is far away, but in fact, at this moment they are surrounded by buildings, to be precise, there are many buildings around Chang'an City, and these people are ordinary people who are attached to the life of Chang'an City.

The city wall of Chang'an City is basically less than 9 kilometers square, that is, an area of 84 square kilometers, but the population of Chang'an City in this area is more than one million.

But in this day and age, a city of a million people...... That's a miracle! And an area of 84 square kilometers is simply impossible to accommodate a million people. I can't even live in two-thirds of it, don't forget, there is a large palace here, as well as the residences of various ministers' families, many of which start from five.

Not to mention that there are many small officials and so on, and the residential area of these people is not small.

In this era, there are no buildings, so you can imagine how many people can live in 84 square kilometers? What's more, there are a large number of restaurants, green buildings and other entertainment venues in this city, as well as a huge area of the East and West markets, etc., so there are really not many people who really live in the city.

At least one-third of the people of Chang'an City, with a population of one million, live outside the city, but there are not many houses near the city wall, and Chang'an City has no moat, but there is a moat under the city wall of Chang'an City, which is similar to a trench.

However, there are rivers passing through Chang'an City, and there are moats in the imperial city of Chang'an City and other places.

Most of the buildings outside Chang'an City are very ordinary, and many of these buildings are also very dense, and it can be seen that they are all people who rely on Chang'an City to live.

"With so many people, if war comes, will it be too late to enter the city?" Huo Gang asked curiously.

"It's definitely too late, besides, if the enemy hits under Chang'an City, in fact, it's no different from defeat, and it doesn't matter if it's defense or not." Li Shimin said lightly, although Jieli did hit the vicinity of Chang'an City, but it was also nearby, and there was still a distance of nearly 100 kilometers from the city.

"That's true." Huo Gang nodded.

"I heard that some of your cities have begun to tear down the city walls? You're not ready to build walls? Li Shimin also asked a question curiously. It's not a secret, now many caravans in Datang have also been to many cities in Dahan, and it's normal for Li Shimin to know all this news.

"That's true." Huo Gang nodded, of course he wouldn't say, because of the appearance of artillery, there is indeed no need to build a city wall in the Han city, although the enemy has no artillery, the city wall is still useful, but if there are artillery and rifles, the enemy can penetrate the territory of the Han Dynasty so far, the city wall is useless.

"The best defense is to attack, and defending the enemy thousands of miles away is what the Han will do next, and the defense of the city wall is actually not very useful in many cases." Huo Gang shook his head slightly.

Li Shimin hesitated, there were some things he wanted to say but didn't know how to say them.

"Your Majesty, please tell me something."

"Then I'm going to put it mildly, if one day something goes wrong with the regime of the Han Dynasty and provokes a popular uprising, wouldn't it be easy to be attacked without a city wall?" Li Shimin still asked this question.

Huo Gang smiled, Li Shimin's words are normal, in fact, most of the ancient Chinese city walls are indeed used for this...... At least the use of regional rebellion, displacement, and rebellion is much more useful than defending against foreign enemies.

"This will not happen when I am alive, and when I die, if a government makes it impossible for the people to live and rebels, there is no need for it to exist." Huo Gang's tone was very calm, to be honest, he didn't want to say this to Li Shimin, because Li Shimin might not understand, but since he asked, Huo Gang also said it.

Sure enough, as soon as Huo Gang's words came out, Li Shimin was stunned, not only Li Shimin was stunned, but even Chang Lin, who was hiding in the corner on the side, was stunned.

After Li Shimin looked at Huo Gang from beginning to end, he confirmed that the expression on Huo Gang's face was not a joke, he was still so calm, and even after Li Shimin looked at it, he had a calm face, as if what he said was not such a shocking remark.

Subconsciously, Li Shimin glanced at his daughter again, Li Lizhen's expression was also very calm, not shocked, which shows that Huo Gang has at least talked about similar topics when he gets along with his daughter every day, and he also behaves like this every day, so Li Lizhi is so calm.

"This ...... I suddenly understood why you didn't call yourself emperor. An irrelevant topic suddenly popped out of Li Shimin's mouth.

Huo Gang was stunned for a moment, he thought that Li Shimin was going to say something to praise him or express shock after being so amazed, but this was the result? Why did you suddenly talk about this?

"Surprised?" Li Shimin couldn't help but smile and asked.

"Oh, no, why do you ask this all of a sudden." Huo Gang was a little curious.

"There's no why, it's just curiosity, not only me, but the entire aristocratic class of the Tang Dynasty is almost all trying to know the answer to this question, no one dares to ask you, but they don't know how many times they have discussed it in private, you must know that your current land area in Dahan is much larger than that of Datang." Li Shimin couldn't help but smile and said.

"Uh, indeed." Huo Gang shrugged his shoulders, then glanced at Li Shimin and said, "Speaking of which, Your Majesty, did you guess it?" ”

"No, I just probably think that everyone in this world wants to be the emperor, it seems that you don't care about this position, and it is not so important, so you are not in a hurry?" Li Shimin asked tentatively.

He was actually guessing, because Huo Gang even said such a thing, obviously he didn't have much idea about becoming an emperor, at least he wasn't urgent, so it was normal not to be in a hurry to become emperor.

"There is indeed a reason for this." Huo Gang smiled, in fact, this is a reason, anyway, his rights are no different from the emperor, what is the difference between being called an emperor or not?

"Oh? Are there other reasons for that? Li Shimin asked curiously.

"Yes, I want to lay down a big land for the Han Dynasty, not just a simple land, but also to rule these lands with culture and related things, and then call the emperor at that time, and claim that this is the inherent territory of the Han Dynasty on the territory at that time." Huo Gang said with a smile.

"What's the point?!" Li Shimin was stunned for a moment, what is the point of this kind of thing? Claim to have a fart? If you don't have the strength, your descendants won't be able to claim it.

"Yes, very much." Huo Gang smiled strangely, of course he couldn't say that this was a strange soul from the later generations who were making trouble, this kind of person who claimed this era didn't care, but in fact, if Huo Gang could rule these places for fifty years.

And if the Chinese language is thoroughly integrated into all places, then it will be influential, and culture is the most terrible weapon.

If Huo Gang's next generation of successors were not so idiots, as long as this culture eroded for more than one or two hundred years, their original language and culture would be completely cut off, and it would be easy to make a cultural fault, this kind of thing is in the hands of a few people in this era.

As long as this generation dies, the next generation will learn about their culture.

It is very easy for Huo Gang to popularize basic education.

Even if Huo Gang didn't destroy their original culture, as long as he educated more than 90 percent of the remaining illiterate people in the West into people with Han culture, then things would be much simpler.

So he's not in a hurry about that.

"Okay, you think you have it." Li Shimin doesn't care when he arrives, anyway, those places are too far away for Datang and cannot be included in the rule, and more importantly, he and Huo Gang have already discussed it, and Datang already has too many new places, enough for them to attack.

In the process of chatting, the convoy quickly approached the gate of Chang'an City, the southernmost gate of Chang'an City has a total of five parallel door openings, which is already very grand in this era, but there are no ordinary people here at this moment.

Huo Gang looked at Chang'an City outside with some curiosity, which was different from what he imagined and the scenes in some film and television works, and could only be said to be similar...... But again, there are plenty of old and dilapidated buildings.

Of course, there are also brand new ones, these new buildings are more shops, restaurants and the like, and there are no ordinary people on the street, but the street is also very stable, because the street is all paved with bluestone slabs.

The antique city is completely displayed in front of Huo Gang, this is the first time Huo Gang has seen the ancient city completely after coming to this world, cities like Dunhuang County do not count, because those places lack wood, etc., so the overall architecture is actually biased towards the stone buildings of the West.

The vast majority of Chang'an City is made of wood, so this is a complete Chinese-style building complex, and the whole city is like this.

"It's getting late today, so why don't you go to the embassy to rest first?" Li Shimin looked at Huo Gang and asked.

"No problem, if you can, Lizhi can go to the palace to see Her Royal Highness." Huo Gang said with a smile.

"I'll go tomorrow." Li Lizhi said very simply.

"Okay, then we'll visit officially tomorrow." Huo Gang nodded, he knew why Li Lizhen did this.
