There is a reason why Tibet has never invaded the Central Plains in the era of war and chaos in the Five Dynasties and Ten Kingdoms.

Since 800 AD, the once powerful Tibetan dynasty has gradually declined, and the Tibetan royal family has fallen apart, once again returning to the era of tribes fighting separately and even attacking each other.

In the end, the great ideal of Songtsen Gampo is still annihilated in the long river of history.

After the division of Tibet, it was mainly divided into four branches.

The Lhasa royal lineage - The descendants of Yundan, the son of Langdama, occupied Lhasa and were called the Lhasa royal line. Most of his forces were in Lhasa, Samye, Duokang and other places.

Ali royal line-Nyimagon, the grandson of Oh Song, abdicated to Ali Bujang as king, and his three sons ruled the Mon domain - Ladakh royal line, and the royal family of Bujang and Zhangxiong - Guge, collectively known as the "Upper Three Gons". After the royal family of Guge, Lama Janqu welcomed Atisha to Tibet.

Yaze royal line - The eleventh generation grandson of Nimagon is called Yaze royal line according to Yaze as king.

Tashi Zoupa, the grandson of Oh Song, had three sons: Bade, Ud, and Kidd, known as the "Lower Three Virtues". The third son of Hude, Chiqiong, formed the royal line of Yalong Jue'a according to the city of Yalong Qin Ondaze, and the descendants of the second son Chide settled in Qinghai and became the king of Tsongkha.

The closest to the Great Zhou is the three lower German departments of the Yalong Jue A Wang line, and the second son of Gande, Chide, is stationed in Qinghai and Gansu.

Guo Zongxun wanted to fight against the armed forces of Cred.

If you put it on the plain, the current strength of the Tibetan tribes is not even comparable to the Khitan, but if you are lucky, you are lucky that he is located on the plateau, and most of the people walk on the plateau is okay, once they run, they will obviously lack strength, not to mention riding horses and guns to fight.

After Guo Zongxun learned about this situation, he decided to take advantage of this great opportunity to break through each other, and absolutely not give Tubo a chance to reunite together.

After studying the current situation in Tibet for a while, Li Hongzhang made a suggestion to Guo Zongxun.

"Your Majesty, the minister suggests that the Chide Department in the Three Virtues be destroyed first, and occupy part of Qinghai and Gansu, so that we can continue to attack the plateau in the southwest, and we can look down on the Hexi Corridor in the northeast, once the Chide Department is taken, the Great Zhou Dynasty can even directly negotiate with the Yundan Department that still occupies Lhasa, and at that time, the initiative in negotiation will be in our hands." 、

Guo Zongxun agreed to Li Hongzhang's suggestion, and the preparation he had asked Zhe Yuxun to make was exactly this, taking the initiative to attack the Chide Department entrenched in Qinghai to deter the entire Tubo.

The Chide Department moved from Lhasa to Qinghai and Gansu, which are relatively close to the Central Plains at a lower altitude, and are catching up with the chaos in the Central Plains.

This was originally a good opportunity for the Tibetan tribes to continue to march east to attack Chang'an, but the Chide tribe had just broken away from the civil strife in Tibet, and had no strength to go down the plateau at all.

After the Chide tribe gradually gained a firm foothold in Qinghai, they heard that the Central Plains countries were in full swing and it was very lively, and they thought that this was a good opportunity to take advantage of the opportunity to advance eastward.

The Tubo people had marched eastward before, attacked the city of Chang'an several times, and even captured Chang'an during the Anshi Rebellion.

Guo Zongxun didn't want to give the Tibetan Plateau a chance to plunder, but he didn't want to defend passively, so the plan to take the initiative to attack the plateau and practice his hands was released.

The executor of this plan is Ori Yuxun.

If the Great Zhou can be forced to negotiate peace with Tubo, and then let the Great Zhou exchange materials for peace every year, it will be very beneficial to the development of the Red De Department.

Therefore, Chide sent a large number of fine works into the Han residential areas east of Xining to inquire about the current situation of the Great Zhou Dynasty.

When Chide learned that the Great Zhou was fighting against the Liao State and the Northern Han Dynasty, and there were also repeated frictions with the Southern Tang Dynasty, he felt that this was not a repetition of the Anshi Rebellion of the Tang Dynasty?

There are wars going on everywhere in the Central Plains, and this is definitely a good opportunity for the fishermen to take advantage of the surprise.

Chide's idea was very good, but there was one thing he didn't realize, that is, the lag of the news, and when he got the news, the Great Zhou had already defeated the Liao State, forced the Liao State to go to the emperor to change the name to the Khitan State, and even the Northern Han had been pacified by the Great Zhou.

Therefore, Chide began to deploy troops and actively prepare for another sneak attack on the Central Plains.

This is also the reason why Guo Zongxun learned that there was an abnormality in Tibet.

When Guo Zongxun formulated a strategy to take the initiative to attack Tibet, the lagging intelligence network of the Chide Ministry passed the news of the Great Zhou's defeat of the Liao State and the conquest of the Northern Han Dynasty.

When Chide saw it, he was dumbfounded, he thought that the mountain was a fat sheep, but he casually bullied it.

As a result, there was a fierce tiger lying down the mountain.

Chide plans to stop fighting, what should everyone do, let's not go to the Central Plains, and wait for the opportunity.

However, Guo Zongxun's strategy has been released, I don't care if you want to fight Chide, anyway, this battle, I have to fight.

When the Chide Department learned that Da Zhou actually took the initiative to send troops to attack, they were a little confused, when did the Han people urinate so much, we are here on the plateau, will you still pant when you come up?

However, what Chide didn't expect was that according to the selection method of the little emperor Guo Zongxun, the ratio of young soldiers to middle-aged soldiers was 64, and while marching all the way to the plateau, he constantly replaced the soldiers who could not adapt to the plateau climate, and then added new soldiers.

Coupled with the conditioning of Rhodiola rosea, a traditional Chinese medicine that is very effective in anti-altitude sickness, Zhi Yuxun even found that there seems to be nothing to fear when going to the plateau.

Of course, Zhe Yuxun is not a person who underestimates the enemy, and the little emperor Guo Zongxun told him to keep it in mind.

"Your Majesty said, you must not rush forward, you would rather be slow, but you must not be defeated, if you lose, I don't have to go back."

This is the death order given by the little emperor to Zhe Yuxun, against Tubo, but all wars, no matter how big or small, are not allowed to be defeated.

Chide's side learned that the Great Zhou army had ascended the plateau in a menacing manner, and it was really a bit of a hurry at first, and the Han people never took the initiative to fight, so they really didn't know what to do.

At this moment, the news came again that several of them had been recruited by the Great Zhou army as guides, and they had now gained the trust of the chief general of the Great Zhou army, so they ......

Therefore, every move of the Great Zhou army, the news that the Chide Department has been transmitting through the detailed work, is almost completely controlled.

"The army of the Great Zhou wants to go to Cuowenbu? This is a good opportunity, coming out of Xining, there will be several forks in the road, several of which can lead to Qinghai Lake, let Xizuo tell the Great Zhou army the farthest and most detoured one, the Great Zhou army will not set up a military station after a while, this is definitely an opportunity to weaken the overall combat effectiveness of the Great Zhou army. ”

"Coming down from Qinghai Lake, there is a road leading to Zhangye, an important town in the Hexi Corridor, and after the Great Zhou army reaches this fork in the road, let Xizuo find a way to lead the Great Zhou army to this road to Zhangye."

"Then, we will lay a net for the Great Zhou army here in the page, so that they will not come back."
