Li Ke felt that this matter was very likely, the Great Wall may not exist, and the Great Wall of later generations was mainly the Great Wall of the Ming Dynasty, but there was no need to build the Great Wall in the current Tang Dynasty.

Li Ke naturally can't build a world wonder just for the sake of a name.

If he guides, and in the future, the Tang Dynasty will not use these gravels to build railways and roads in the grassland, but tell those herdsmen through propaganda that these gravels represent the spirit of the grassland people, their faith, their determination to yearn for a better life, and their expectations for future happiness.

The stone walls formed by these rubbles will only increase.

Anyway, when the road was first built on the grassland, it was definitely impossible to get on the concrete road, there was no need. At most, it is rammed earth, which constantly compacts the road and then forms the road.

Gravel paving is also unlikely, gravel is easy to say, but sand is not so easy to make.

However, it is impossible to pave the road directly with these gravels, which are angular and have the potential to break the tires that will be used in large quantities in the future.

As for the construction of the railway, there must also be a standard for gravel, and it is likely to be professionally transported from a further place.

However, even if such a thing seems meaningless in the end, in fact, it brings cohesion, faith, group effect and other benefits!

After all, on the green grassland of the future, a stone wall that spreads like a spider's web all over the grassland is also shocking, isn't it?

Maybe in the future, this is one of the wonders of Datang.

When the ministers of Chang'an were shocked by this incident, in the northeast of the Tang Dynasty, a person was a little distressed because of this incident.

This person is none other than the Khan of Murowei, the Khan of Gunawei.

Although Murwei is collectively referred to as Murwei to the outside world, Murwei is not like the Eastern Turks, nor is it like Xue Yantuo who is a whole and has a great khan. In later generations, it was more like a federal state.

There are four large tribes in total, and these four large tribes are composed of many small tribes, so it seems that Murwei occupies very rich mountains, forests and grasslands, etc., but it has not been strong.

The reason why Gu Nawei Khan was distressed was because his territory was next to Xue Yantuo, and when Xue Yantuo became Hanhai Prefecture before, the governor of Hanhai Prefecture sent someone to inform it.

Also as a vassal state of the Tang Dynasty, it must be normal for the other party to inform them.

At that time, Gu Nawei didn't think much about it, of course, there must be ideas, after all, Datang had already told them why Zhenzhu Khan went to Datang and what benefits he had gotten.

Tens of millions of dollars went to Chang'an to enjoy, and at that time, Gu Nawei Du wanted to scold people.

The problem is that Datang didn't say that he would go to Chang'an, and Gu Nawei naturally couldn't take the initiative to say that he wanted to go, but things were different later.

Hanhai Prefecture began to carry out activities such as building roads and building Ao Bao, and more importantly, Datang distributed cattle and sheep to all Xue Yantuo herdsmen, and these cattle and sheep belonged to these herdsmen themselves!

The cattle and sheep of the original nobility were divided!

Who can stand this? In the past few months, he has received more than one report that many herdsmen in his tribe have fled to Hanhai Prefecture.

And after these herdsmen ran over, they became herdsmen in Datang directly in Hanhai Prefecture, and they were also assigned cattle and sheep pastures there, and then when they worked together, they also gave them grain and salt!

As a result, in the past two months, he has run nearly a thousand herdsmen here!

Gu Nawei wants to scold! Pearl Khan is not a son of man! You're running away to enjoy the blessings, and you've left us with so much trouble.

"Khan, I have an idea." Inside Gu Nawei's tent, a man with a fat figure spoke.

This man is Gu Nawei's younger brother.

"Say." Gu Nawei glanced at him angrily and said.

"Khan, if you are not ready to be hostile to the Tang Dynasty, I think we might as well take the initiative to go to the book, and we will also go to Chang'an?" The younger brother of the Khan of Gunawei spoke.

"Huh?" Gu Nawei was stunned for a moment.

"Khan, you see, that Zhenzhu Khan has a much bigger status than ours, since this is the case, he agrees to this, obviously Datang's attitude is naturally very tough, no matter how Datang is, Xue Yantuo and others have become Hanhai Prefecture, and it is only a matter of time before we are here."

"In this case, instead of talking about it in the Tang Dynasty, it is better for you to go directly to the book yourself, and then we will have to ask for a better treatment, if nothing else, maybe Khan you will be able to compare to the status of Zhenzhu Khan in the future." Gu Nawei's younger brother said directly.

Gu Nawei Khan was stunned for a moment, and then he pondered, and I have to say that what his brother said made sense.

As for fighting, he didn't think about it at all, because he couldn't beat it at all, and the four khans of Murwei alone couldn't work together with each other, let alone against Datang.

Not to mention the Tang Dynasty, even if it is the neighboring Goguryeo, they are not opponents, Goguryeo has eroded a lot of their land over the years, if they don't belong to the Tang Dynasty, I'm afraid that Goguryeo will continue to occupy their land.

This is a good idea, if you take the initiative to vote for the Tang Dynasty, according to His Majesty the Khan, I guess the treatment for myself will not be bad, right?

At that time, the bitter cold land of this room will be handed over to Datang.

Unlike Zhenzhu Khan, Gu Nawei is adjacent to Goguryeo, and Goguryeo is actually very similar to the culture of the Tang Dynasty, and the words are basically Tang dialect and Tang characters, and some cities in Goguryeo are also very prosperous.

So Gu Nawei knows very well that these cities are much more comfortable than his room, what is the use of staying in this place? Although the name is a khan, this thing does not bring any new enjoyment.

"Then I'll write a letter." Gu Nawei said very dryly, he didn't expect this before, his younger brother has always liked to eat, drink and have fun, which reminded him.

Although his original intention is probably to follow him to Chang'an, I am afraid that he will not get a lot of rewards, but in any case, he finally came up with a good idea for him.

After making up his mind, Gunawei Khan directly began to write the letter of state, and then sent envoys directly to Chang'an.

It's not that hard.

It's just that when Gu Nawei's letter was sent to Chang'an, more than a month has passed, and Chang'an, which is close to November, has entered the early winter, and Chang'an in winter this year is particularly lively, mainly because the latest farmland output has been thoroughly counted, so this year's Chang'an City, almost all officials are happy.

The world has a bumper harvest, this is a happy event, Your Majesty is naturally happy, Your Majesty is happy, and the officials below will naturally live a good life.
