Zhao Zhen was so comfortable eating pastries and drinking tea. The battle between the two women outside the hall had little to do with him. At least they could hide for a while now. They still had to deal with such things themselves, otherwise they would be biased no matter what they did.

One is the queen, the other is the former emperor and the current imperial concubine. The queen he defaults to is the best among women. Zhao Zhen does not want the two phoenixes to fight to hurt him.

The smart eunuchs were far away from Qingliang Hall at this time. This place can be regarded as the Eye of the Storm. Once they are caught in, they will definitely be crushed to pieces, and Zhao Zhen will not interfere.

At least such a stalemate will soon disappear. Both of them have identities. Staying here for too long will inevitably lose decency. Face is more important for women.

Putting down the tea bowl, Zhao Zhen sighed slightly as he looked at the information about Tubo. This dynasty was once a prosperous period. If it weren't for the natural plateau disease of the Tubo people, it would have been uneasy to the Central Plains.

Even so, it caused a heavy blow to the Li Tang Dynasty. After the "Da Feichuan dispute", the war between Tubo and the Li Tang Dynasty broke out in full swing. After the death of Lu Dongzan, the great prime minister of Tubo, Tubo completely lost his calmness.

If Songtsen Gampo was the revival of Tubo, then Lu Dongzan was a wise minister of Tubo. This man was a wise man on the plateau, an outstanding politician, military strategist, and diplomat.

During his envoy to the Tang Dynasty, Lu Dongzan was very smart and fickle, and was highly appreciated by Emperor Taizong of Tang. He wanted to marry Duan, the granddaughter of Princess Chang of Langya, to lure him to serve the Tang Dynasty.

Regarding the recruitment of Emperor Tang Lu Dongzan, the emperor of the Tang Dynasty, politely declined Taizong's kindness on the grounds that "the minister has a wife in his own country, and his parents hired him, and he couldn't bear to be behave. Moreover, Zan Pu did not pay homage to the princess, so how dare he marry him?" This politely declined Taizong's kindness. This was neither decent nor failed to force him to submit.

After Songtsen Gampo's death, the entire Tubo was almost relied on Lu Dongzan to maintain stability. In front of him, he had been committed to maintaining the stability of Tubo, the reform of the system and the inheritance of Songtsen Gampo's attitude towards external expansion, but he restricted Tubo from being cautious in using troops against the Tang Dynasty.

But after his death, the Tubo people lost this important "helmsman" and began to constantly invade the territory of the Tang Dynasty.

The Battle of Dafeichuan made Tubo powerful, and also caused the Tang Dynasty to change its original contemptuous attitude. In order to defeat Tubo and completely eliminate the dangers of the western border, Emperor Gaozong of Tang sent Xue Rengui as the chief general of the Lusadao Army, and appointed Ashinadaozhen and Guo Tie as deputy general, leading a 50,000 army to attack Tubo.

Xue Rengui ordered Guo Daifeng to lead 20,000 people to guard the baggage at Dafeiling. Xue Rengui's commander advanced, attacked Tubo at the mouth of the river, and defeated it. He captured a lot of people and arrived in Wuhai.

Guo Daifeng did not implement Xue Rengui's plan and led the baggage and was defeated by more than 200,000 Tubo's troops. All the baggage was abandoned and Xue Rengui's troops were forced to return to Dafeichuan. Tubo Lun Qinling led more than 400,000 troops to attack, and the Tang soldiers were defeated.

After that, the war between Tubo and the Tang Dynasty sometimes did not occur. Both sides won and lost each other, but they failed to defeat each other. The biggest barrier was the plateau.

The Tubo army could not come down for too long, and the Tang army could not fight on the plateau for a long time. After that, with the efforts of the female emperor Wu Zetian, the Tang Dynasty recaptured the four towns of Anxi, and coupled with the internal power struggle, Tubo's strength began to decline.

Looking back, Zhao Zhen couldn't help but sigh: "The way of heaven is good for reincarnation!"

While the strength of Tubo declined, the Tang Dynasty also experienced the deathly Anshi Rebellion, and the strength of the dynasty also dropped sharply. Tubo took advantage of the victory and drove straight into Chang'an. Emperor Daizong of Tang hurriedly fled to Shaanxi Province. The Tubo army occupied Chang'an and supported the Tubo uncle Li Chenghong as the emperor.

However, the foreign army was not adapted to the scorching heat in Chang'an in autumn, and the disease prevalence among the Tubo army. In addition, the Tang Dynasty's army was approaching, and the Tubo army entered Chang'an for fifteen days and withdrew from Chang'an. At this point, all the thirteen states in the eastern section of Longyou Road were trapped in the hands of Tubo.

At this point, Zhao Zhen learned part of the war between Tubo and the Tang Dynasty, and also knew that the struggle between the two sides did not have much introduction in history books. The process was complicated, the use of troops was complex, and the number of strategies was dazzling.

Putting down the scroll in his hand, Zhao Zhen began to sort out the information he had.

In the early years of the Tang Dynasty, most of the surrounding ethnic groups had obvious military advantages, except for Tubo. In addition to the reasons for military command, there were many other reasons... The most obvious one was that the Tubo country had strict laws, joint efforts from top to bottom, relatively stable internally, fierce and martial, and the military and geographical situation in the Helong area was very beneficial to it.

There is also Tubo located on the Qinghai-Tibet Plateau. When attacking Tang, it could be placed in a high position and went straight to the plains; while when Tang attacked Tubo, it had to attack the high-altitude and oxygen-deficient Qinghai-Tibet Plateau, which was very inconvenient to march and fight.

While the plateau became the advantage of Tubo, it also became the biggest bond of Tubo. Without foreign aid, the Tubo people could hardly pose too much threat to the Central Plains, and even if they captured the capital of the Tang Dynasty, they could not defend it.

The Song Dynasty is not like the Tang Dynasty, and it has always pursued a defensive policy towards Tubo. In addition, the Tubo was a mess, so it did not threaten the Song Dynasty, so it was left alone.

Now, the sudden rise of Jiao Siluo has caused the central and six well-read history masters to worry. They are worried that Jiao Siluo will become another Songtsen Gampo, and they are also worried that Tubo will be unified under his attack.

Zhao Zhen was not surprised by the concerns of the center. He was not surprised by Yu Weiran. This was what the master should do, especially the rapid progress of Jiao Siluo during this period.

After reading so many historical materials, Zhao Zhen basically clarified the history of Tubo and the origin of the current split. His purpose of supporting Jiao Siluo was to make him an anomaly participate in the chaos in Tubo.

Because of his special identity, he was descended from Zamp of the Tubo Dynasty, because of this identity, he was used countless times. He was a descendant of the noble Yalong Jue'a kingdom of Tubo, but he was born at the wrong time.

When he was born, Tubo had already fallen apart and was in the midst of civil strife of royal family wars and warlord separatism. In order to take refuge, many descendants of the Tubo royal family had to go far away.

When he was twelve years old, he was taken back from the Western Regions by a Qiang man named He Lang Yexian. At that time, the power of the Tubo country had long declined. Tibet was divided into various parts; in the Helong area, there were even "races scattered, with thousands of families with the largest families and hundreds of families with the smallest families, and no longer unified."

After being taken back, although the servant was nominally the supreme Zanpu of Tubo, he was actually a puppet in the hands of religious leaders and local tyrants in Hehuang area. At that time, the two powerful religious and local tyrants in Hehuang area both chased the servants as precious prey.
