As for the problem of bridges and tunnels, in fact, the most valuable thing for Li Ke here is that he has the experience of countless martyrs in exchange for their lives, as well as many advanced construction methods.

For example, the bridge, China's earliest cross-river bridge, the later Wuhan Yangtze River Bridge, was built by the pipe string drilling method, the difficulty of this construction is not too high as a whole, if you have to play, Li Ke is now also playing.

"Seven or eight days? Is this true? "Everyone was stunned.

What is the concept of arriving in the Western Regions from Chang'an in seven or eight days? It is about three thousand miles from here to the countries of the Western Regions, and it can be reached in seven or eight days? Wouldn't it be 400 miles that day?! If there is really this speed, wouldn't it be like playing for Datang to control the Western Regions.

"Of course it's true, I'm not just talking about cavalry, including infantry, food, grass, weapons and armor and everything else." Li Ke said lightly.

Now everyone is not calm, if they arrive in the Western Regions for seven or eight days, doesn't it mean that it will only take twenty days from Chang'an to Persia? Or even shorter? At this time, even if the Tang Dynasty rushes to Persia, there is no problem!

As for the further north, not to mention, wouldn't it be easier?!

"So, you don't have to worry that Datang can't control your own land, you just need to worry about whether the progress of your strategy can keep up with Datang's footsteps." Li Ke waved his hand, "Now let's talk about this Tubo incident." ”

"Since there are serfs rebelling in the entire Tibet, and Li Daozong has sent 30,000 cavalry into Tibet, we only need to get stuck in this direction now." Li Ke directly stretched out his hand and clicked on the Yadong Pass on the map.

There are actually many places that have crossed the Himalayas in later generations, but for this era, it was possible to cross the Himalayas in large numbers...... It's really too little. If anyone dares to challenge these passes with a large army without the logistics supplies prepared in advance, it is really looking for death.

"Therefore, when we control here, it means that the entire West Kunlun Mountain Range will become a natural barrier for our Datang, and the Yadong Pass will be our natural pedal, and this place means that we can attack and retreat."

"It will play a key role in our future footing on the Tianzhu Peninsula." Li Ke drew a circle on the Himalayas, and the entire Himalayas have been renamed the West Kunlun Mountains by Li Ke, and the Kunlun Mountains are naturally still the original Kunlun Mountains.

For this era, the Himalayas are really the natural barrier of the Tang Dynasty, and the reason why the original Datang could not set foot on the plateau had an indescribable relationship with faith and the plateau environment, and after taking Tuyuhun, the restrictions of the Tang Dynasty in this regard were completely gone.

In the original territory of Tuyuhun, the altitude is also not low, and the herders living in these places naturally have no problem entering the Qinghai-Tibet Plateau.

"These are not problems, but Your Highness, are you sure that these serfs in Tubo rebelled and had such a high sense of belonging to our Tang Dynasty?" Li Jing hesitated and asked.

"Definitely, it was my people who instigated them to rebel, of course, after bringing them into the management of the Tang Dynasty, we need to treat them equally, just like the herdsmen of Tuyuhun, or even better than the herdsmen of Tuyuhun!" Li Ke nodded as a matter of course.

Everyone was a little speechless, looking at Li Ke's eyes as if they were looking at a fairy.

Going to the army to fight and plotting, and surrendering the soldiers without a fight, this is the highest level of the art of war. If this is the highest level of the art of war, then what kind of realm should this be for the whole country that surrenders without a fight? Although His Highness has bought several countries such as Wuqiang, those countries that are only the size of a county are the difference between heaven and earth and countries such as Tubo!

This is not a level at all, if attacking the city is like His Highness, what is the use of asking them generals?

"Good! is worthy of being my Li Shimin's son, well done, then you have to be responsible for the follow-up management of Tubo now, otherwise, if you can't reach the same situation as Xizhou here, it won't be a disappointing plan. Li Shimin shouted a good way.

Wei Zheng: "......"

Fang Xuanling: "......"

Your Majesty, are you really not hiding it at all? The problem is that if you arrange these jobs for Your Highness again, Your Highness will probably run away.

Li Ke: "......"

"Dad, if I do all this, what do you want the three provinces to do? This is a matter for Shangshu Province. Li Ke looked at Li Shimin helplessly and said.

Fang Xuanling: "......"

I'm guilty, what I just thought was wrong, but what His Highness said is right, this is indeed a matter of their three provinces. Your Majesty can run, but they can't, but although I can't run, I can find a way.

"I think it's better to transfer Li Daozong to protect the Qinghai-Tibet region, oh, since this place belongs to my Datang, I think it's better to name it Qinghai-Tibet Dao?" Fang Xuanling said directly.

Li Ke rolled his eyes: "I said Liang Guogong, can you let go of my future father-in-law." The hair is about to be bald by you. ”

Everyone was a little speechless, good guy, Your Highness, your shameless character is really impossible to inherit, Your Majesty and Concubine Yang are not this character.

"Your Highness's words are wrong, this is to promote Li Duhu." Fang Xuanling said.

He was right, the governor was the number one military and political leader, and he was divided into large, middle, and small according to the size of the population and region. The governor of the capital is a substantive official from the second grade, which can be said to be an emperor of one side, and the highest governor of a province is theoretically called the jiedu envoy, but in fact, in the frontier of the Tang Dynasty, because it is far away from the administrative center of the imperial court, the jiedu envoy and the metropolitan governor are often one person.

In fact, the population of Tibet is not small, the population of the whole Tibet is about 2 million to 3 million, and the peak of Tibet can reach about 4 million in the future.

Although this population is not comparable to that of places such as Guannei Province, if Tubo establishes Qinghai-Tibet Road, its area will be large! This is definitely at the level of the Grand Governor.

In the Tang Dynasty, the rank of the Grand Governor is higher than that of the Central Governor, although both sides are the same.

Including the top governors of the Tang Dynasty, the history of the assassination is also divided into large, medium and small levels.

"Speaking of which, I think these local official positions in Datang also need to be changed, and the current system is too complicated and cumbersome." Li Ke opened his mouth and added.

Everyone: "......" Can you not remember that one is one play, our three provinces have just been restructured not long ago.

"In fact, there are not many places to change, mainly not divided into large, medium and small, the highest level of the governor of all provinces is the same in the grade, and the other is to distinguish the local functions and powers, for example, the military department should set up a separate military region, the military region should be divided according to the provinces of the world, and the military region is independent of the military units of each province."

"In terms of local administration, according to the current system of the Tang Dynasty, the supreme governor is responsible for supervising the administrative development of a province, and the supervision of the imperial history is appointed, dismissed and approved by the supervision committee of Menxia Province."

However, the day-to-day administration and implementation of the Governor is the responsibility of the Governor, and the appointment and dismissal of the Governor is vested in Shangshu Province and submitted to the Zhongshu Council for approval. The two sides figured it out in terms of grade, but the governor was slightly half a level lower than the superintendent of the imperial history. Li Ke probably proposed a charter.
