In the yamen of the state capital of Chengdu Prefecture, Li Chu took out a satellite aerial map, and then revised the map according to the information sent by Gao Mingshun.

Among the Tibetan tribes, there are three tribes that are geographically bordered by the Great Song Dynasty.

One is in the northwest, in the northwest.

In addition to the junction with Qinfeng Road in the Great Song Dynasty, there is also a part of the border with the Western Xia Kingdom.

The Achai Department, on top of the Tusi Ma Department, controls Qingtang City, one of the five cities in Tubo, which is at the junction with Western Xia and Huangtou Huifu.

The other two, one is the Uth Division.

Originally, the Wusi Department did not border with the Great Song Dynasty, but with the junction with Yunnan Dali, and now with the merger of Dali into the Great Song Dynasty, it became the Yunnan Road of the Great Song Dynasty, and the Wusi Department also bordered the Great Song Dynasty.

And to the southeast of the Wusi Department and the Tuosi Ma Division, there is a tribe called the Dare Division.

This tribe has a relatively large territory, occupying one-fifth of the territory of Tibet. The main junction with the Great Song Dynasty is this Dangbu, from the Qinfeng Road of the Great Song Dynasty to the south to Shanju County of Yunnan Road, the west of this boundary line is the territory of the Dangbu.

Although this dare department occupies one-fifth of the entire territory of Tibet, its department is a relatively low-key party among the Tibetan tribes.

Although the territory is large, this military strength is not as good as that of the two neighbors.

And not long ago, the Tuosi Mabe also coerced a daughter of the King of the Dare to marry the prince of the Tuosi Mabu, at the beginning of this matter between the Tibetan tribes but caused a lot of turmoil, and finally the two of the two fought a battle under the Bayangela Mountain, the Dangbu lost, had to send the daughter over.

On the map, Li Chu marked and annotated the locations of the Dangbu, Tusi Mabu, Achaibu, Wusi and other tribes on the map, and also marked the locations of the Tubo tribes in the west on the map one by one, according to the information sent by Gao Mingshun.

In this way, a map of the strength range of the Tibetan tribes took shape.

After finishing, Li Chu asked the customization system to scan the map of the Tubo tribes that he had modified and annotated and scribbled, and asked the customization system to remake a complete and clean map according to the graffiti on the map.

The new map shows the sphere of influence of each Tibetan tribe in a different color block.

In this way, this new map of the Tibetan tribes can clearly understand the situation in Tibet at a glance.

After getting this, Li Chu was thinking about how to enter Tibet.

The reason why Tibet is called Tubo is so mysterious, and the reason why the western border of the previous dynasty stopped at Chengdu Mansion is because of this Tibetan plateau.

Sichuan is a basin, and further west are the endless alpine mountains with very high altitudes.

As soon as the altitude is high, people will develop a disease called 'altitude sickness'.

The so-called altitude sickness is a variety of pathological reactions produced by the human body after being rapidly exposed to a low-pressure and low-oxygen environment, and it is a common disease unique to plateau areas. Common symptoms include headache, insomnia, loss of appetite, tiredness, difficulty breathing, etc. Headache is the most common symptom and gets worse at night or in the morning when you wake up. Increased ventilation of the lungs, such as breathing through the mouth and light activity, may reduce headaches.

The incidence of altitude sickness is related to the speed of climbing, altitude, length of residence, and physical fitness. Generally speaking, when plain people quickly enter the plateau above 3000m above sea level, 50%~75% of people have altitude sickness, but the symptoms gradually disappear after 3~10 days of habit.

It's easy to serve this altitude sickness.

Two words, adapt!

For example, first climb the area at an altitude of 2500 meters, stay in this area for a few days, and then start to climb the area at an altitude of 3000, and then adapt to it for a few days, and then climb the area at an altitude of 4000, when the area at an altitude of 4000 can be adapted, then the altitude sickness of the entire Tibetan Plateau will not appear again.

Fortunately, Li Chu was also prepared for this matter.

That's Dali!

This is also the reason why Li Chu wants to take Dali.

The topography of Dali is also an area with continuous mountain ranges.

It's just that his altitude is not as high as that of the Tibetan Plateau, so terrifying.

The average altitude is about 1,000 to 2,005, and the closer to the Tibetan border, the higher the altitude, which can reach more than 3,000.

Tubo, this is a place that Li Chu must take.

Therefore, laying down Dali is for military training.

Let the army first adapt to the plateau terrain and the plateau climate on the side of Dali, and then enter Tibet, there will be no more so-called altitude sickness. Without altitude sickness, the biggest enemy, what can we do with the continuous mountains of Tibet?

Once this veil is lifted, there will be nothing left in Tibet.

At least for now, because of the long-term war, the military strength of Tibet has declined very quickly.

Because, according to the information passed on by Gao Mingshun.

As the most powerful Wusi department among the Tibetan tribes, the overall number of capable soldiers is only 30,000!

Thirty thousand, what is this concept?

These 30,000 also include a large number of children around the age of 11 and the elderly over 50.

The strength of the other ministries will only be lower than that of the Wusi Ministry.

From Chengdu to Tibet, there are three roads.

One is to enter from Lizhou and follow the ancient road into Tibet.

One is from the Minjiang River in the west of Chengdu, and after crossing the Minjiang River, there is a mountain road there, which can enter Tubo, but this road is a small road, and it is not convenient for the army to move forward.

The remaining one is from Yazhou.

This Yazhou is the route that Li Chu led the army into Yunnan, the difference is that this route has a branch in the west, and this branch can enter Tibet. This is a river called Shiyang River, this river flows out of the Tibetan Plateau, and the river washes out a relatively wide impact plain, just like the road to Dali in the south.

This road can accommodate large armies to enter.

There is also a road from Dali, but this road is more difficult, and the mountain is also the highest and most precipitous position, and it also has to pass through a large number of uninhabited mountains and forests. Gao Mingshun entered Tibet from this route.

However, this attack on Tibet must have an excuse.

Sir wants me to make some trouble here.

In that case, why not make a bigger deal out of it? In this way, there was also an excuse to enter Tibet.

Li Chu made a phone call to Li Han and asked Li Han to arrange for two thousand Qilin Army soldiers to wait for the order.

These two thousand soldiers have all adapted to the plateau in Dali, but they have only stayed at an altitude of 3,000 at the highest level.

3000 altitude, enough.

From the satellite map, he has already learned the altitude of the area west of Yazhou.

"Customize the system, I want to customize two thousand sets of clothes and weapons of the Tubo Dare Division."
