Du He saw that Li Shimin understood what he meant, and he also spoke more energetically.

"In addition, 100,000 of them entered our Datang Dynasty and destroyed our Datang fields, intending to occupy our state city and let go of their crimes, which is outrageous. So, why not let them accompany us with some land and cede a piece of land to us as compensation? This kind of thing should be common in history! ”

Li Shimin thought at first that Du He was just trying to make money, and he laughed secretly in his heart, although Du He's move was a failure, but it had to be regarded as a clever move. The Tibetans were not rich in the first place, and the death of nearly 100,000 troops had dealt them an incomparably heavy blow, and if they were forced to pay a high indemnity, they would definitely be forced into a difficult situation, making it even more difficult for them to make a comeback.

But then when he heard Du He's words talk about the land, the people were also moved.

During the Spring and Autumn Period and the Warring States Period, it was not uncommon to cede land and seek peace. It is not surprising that various countries even exchanged cities, and it is even recorded that the king of Qin was even willing to cede fifteen cities to Zhao for the sake of peace.

But since the unification of the world, the matter of land cutting has gradually decreased.

In the Tang Dynasty, there was almost no such thing as land cutting. If you want land, you can only fight with strength, and no one will intentionally cede territory.

Therefore, Li Shimin didn't expect Du He to have such a move, and stood up movingly.

What a man he was, following Du He's thoughts, he already understood everything: he had reached an agreement with the Zhangxiong Kingdom to secretly support the Zhangxiong Kingdom against Tibet.

According to his understanding, it turned out that Zhangxiong had 150,000 soldiers, while Tubo had 250,000 soldiers, so Zhangxiong had been suppressed by Tubo on the Qinghai-Tibet Plateau. But now the 100,000 soldiers of Tubo have almost been wiped out, and the national strength has also been greatly damaged, and the situation on both sides has been reversed.

Although Tubo has a male master, in the face of the gap in strength and his own partial help, it is not easy for Tubo to defeat Zhangxiong.

If he exerts some pressure on Tibet in the rear, Tibet may even perish.

Therefore, it is certain that in order to avoid such a bad state of affairs, as long as he forces Tibet to cede territory by forceful means, there is a great chance that Tibet will compromise. It is not easy to achieve the miraculous effect of driving people away without a fight.

It's just that the one-third of an acre of land in Tubo is barren and remote, and the environment is not conducive to the survival of the people of the Tang Dynasty, is it worth treating yourself like this?

To put it bluntly, he Li Shimin has a big heart, and he is interested in the territory on the Silk Road in the Western Regions, and he does not look down on the land in Tubo that is not conducive to their survival.

Li Shimin told Du He about his doubts.

Du He glanced at Li Shimin with some idiocy and said, "Uncle Li, you don't know!" Today's Tubo occupies the Qinghai of Tuyuhun, do you know the wealth of Qinghai? ”

Li Shimin put his mind on the Western Regions, and he didn't know much about Qinghai, but he knew that in the later period of the Western Han Dynasty, Xihai County was placed on the north shore of Qinghai Lake, and the northern part of Qinghai was also their territory during the Sui Dynasty, but because it was remote and located on the plateau, it was not taken seriously.

After Li Jing led the army to break Tuyuhun, he occupied Qinghai, but it was also because the climate there was not suitable for their Tang people, so he returned it to Tuyuhun and let Tuyuhun continue to take care of it.

Not long ago, the Tibetan invaders, occupied Qinghai, and after the retreat of the Tibetans, due to altitude sickness, the Tang army did not pursue, so Qinghai was still in the hands of the Tibetans.

He didn't pay enough attention to it, and he didn't care.

As for the original owner Tuyuhun, he no longer has the strength to recapture Qinghai.

Du He said solemnly: "In fact, this treasure land in Qinghai is not inferior to my Chaojiangnan, and even surpasses it!" ”

"Impossible!" Li Shimin has no doubt about this, the economic center of the Tang Dynasty has not yet moved to Jiangnan, but the Jiangnan region is rich in salt, rice and other materials are indispensable to the Tang Dynasty.

Qinghai is comparable to Jiangnan?

It's unbelievable!

"I heard my master say that Qinghai is attached to the plateau pastoral area, and the grassland in the pastoral area is vast, the pasture is abundant, and it is the most suitable for animal husbandry. In addition, the territory has high mountains, diverse terrain, rivers and lakes, and dozens of salt pans. Du He's understanding of Qinghai comes from a vague memory in his mind, he once went to Tibet Province to do ten tours, Qinghai Lake is a must-visit, knowledgeable tour guides will introduce Qinghai Lake in detail, so that they outsiders are eye-opening.

Hearing "Yantian", Li Shimin stood up movingly and shouted: "Is this true? ”

He didn't have much thought about the plateau pastoral area that Du He said at the beginning, what is the use of asking for a piece of land suitable for animal husbandry in Datang, which is mainly farming? But when I heard about Yantian, I had to pay attention to it.

Guanzhong lacks salt, and all salt is transported from the south of the Yangtze River through the Beijing-Hangzhou Grand Canal. If Qinghai really has dozens of salt pans in the first generation, it will solve the dilemma of salt shortage in Guanzhong, and there will be no need to transport salt for thousands of miles.

"It's true!" Du He remembers this very well, because Qinghai Lake is a famous saltwater lake.

In fact, the treasures of Qinghai Lake are far more than these, there are countless prey, and the mineral reserves rank first in the country. It's just that these Duhe don't have a deep memory, and I'm not sure if it's correct.

But dozens of salt pans are enough to make Li Shimin's heart move.

"Uncle Li, there is another wonderful thing about letting Tubo cede Qinghai! Because our people are not accustomed to the plateau climate, there is no good way to deal with Tibet, but as long as we can come to Qinghai and send troops to garrison it, it will not take half a year for the soldiers to adapt to the climate there, and our army will not be afraid of any altitude sickness! If they dare to be rampant, they will definitely be able to make them come and go. Du He continued to tempt that no matter the long-term perspective or the immediate benefits, he could force Tubo to cede Qinghai, which was absolutely beneficial and harmless for the Tang Dynasty.

Li Shimin pondered for a moment, and suddenly burst into laughter: "Let your heart move, so decide." This Qinghai, I am going to decide, but I really can't do it, so I refused Tubo's request for peace and attacked back and forth with Zhangxiong State, and forcibly took Qinghai! ”

Seeing that Li Shimin had made up his mind, Du He also breathed a sigh of relief and praised the emperor in a loud voice.

returned to Cai Guogong's mansion and found that Du Ruhui was not sleeping, but waiting for him, seeing him come back, he pulled him and asked him to explain the meaning of the words before leaving.

Du He could only tell Du Ruhui about the land repayment.

Du Ruhui's beard curled when he heard this, and he snorted: "This idea is damaged enough, but it's quite interesting!" gave such a specious evaluation, and I don't know whether to exaggerate or depreciate more.

The next day, Li Shimin changed his friendliness from yesterday and took a stern attitude towards the Tibetan envoys.

What is shown is no longer the tolerance and benevolence of the Tang Dynasty, but the attitude of treating his defeated generals as a victorious country.
