"Your Majesty, Tubo was just a primitive society before the current Zanpu Songtsen ascended the throne. They are the same as our Yan and Huang Emperor periods. But after this Zampu came to power, he began to change to the slave era. And Your Majesty, you may know that at every stage of the transformation of the era, the country will burst out with tremendous combat effectiveness. Wealth, profit, and glory will all be gained in this period of transition. And this transition period can actually make many people from a worthless person to a tribal leader, or even a rich person. At that time, Xia Qi crusaded against foreign races and achieved the world, and the military officials of that period fought bravely in order to obtain benefits, just to obtain land, slaves, and then live a rich life. ”

Later, we explained it in terms of the Shang Dynasty Reform Period. During the Shang Dynasty Reform Period, in order to obtain the title and obtain their own land, the soldiers fought bravely to kill the enemy, and as a result, they broke out with huge combat effectiveness. Therefore, your Majesty, this is actually the embodiment of combat effectiveness. And in this period of social transition, the whole country is very aggressive. During the period of social transition, they will begin to expand and make their land slaves more wealthy. Therefore, in the future, Tibet will undergo a social transformation, and they will burst out with very strong combat effectiveness and full of aggression. ”

Li Shimin thought about it carefully, and he found that this was indeed a problem. Tibet was originally a primitive society, but now it has the embodiment of a slave society. This is actually a social transformation, their fighting power in order to obtain wealth, soldiers in order to obtain honor, and even for profit, those Tibetan officials will support the expansion one after another. And the army is also the time when the combat strength is at its strongest, and peace alone cannot restrain their expansion at all. Only then did Li Shimin realize how stupid he was when he first wanted to appease Tibet by relying on his relatives. Sooner or later, they will also expand, and it is not something that can be solved by marrying a princess at all.

Li Shimin then asked curiously: "We have completed these two transition periods in Huaxia. It took a full one or two thousand years, but why did Tubo finish it so quickly? Also, listening to what you said, I probably understand that the reason why those steppe peoples were able to burst out with such a powerful strength was actually undergoing social transformation, so they were able to constantly oppress us. Once their social transformation is complete, they will not be as good as us. But why did it take so long for me to go through this social transformation, but they were so fast? ”

Jingwen could only helplessly explain to Li Shimin what is called a late-mover advantage. The so-called late-mover advantage is actually the experience of the predecessors, so that they can achieve the Cheng dù of their predecessors in a short period of time. It's like being the first person to run trail. That's often the responsibility for finding the way, and there are a lot of dangers. And the people who ran behind saw that the people in front of them were in danger, so they were able to deal with it quickly. And they also have the experience of their predecessors, and they can quickly chase after them. Even, they can take shortcuts, and it is a great cheat cheat.

And those other ethnic groups are to learn the lessons of Chinese civilization and learn the lessons of Chinese civilization, and then they can only be able to learn in just a hundred years. It has completed the road that China has only completed for thousands of years. This is actually the influence of the Chinese civilization, which allowed them to quickly complete this road, and a large amount of combat power broke out in it, so they would invade China in turn. At that time, there was no civilization in China to refer to. Naturally, the process is slow. However, those nomads and so on, they could refer to the Chinese civilization, so they quickly carried out internal social reforms. It can be said that all of them are influenced by China. Then they came again to invade China. However, China has gone through a period of social transition, and its natural combat effectiveness has declined.

"Your Majesty, our Datang Dynasty has just opened the country. It can be said that the period of the strongest combat effectiveness. But how long can this period last? Although we can have firearms, we can have many advanced troops, but how long can these last? So, we may not be able to stay ahead of them for long. In the process, they can also continue to learn from us. And they will probably be in this so-called period of social transition in the next hundred years, but we in China will live a long time because of the peace, and the army is not aggressive, and finally continue to be depressed. But at this time, the Tibetan people are the most aggressive, their ambition can be said to be insatiable, and they use their strongest strength to meet us when we are the weakest, so what will happen to us? ”

Therefore, the minister thought that Tibet was the biggest threat. The surrounding countries, whether they were Turkic, Tuyuhun, or even Tianzhu in the south, have all passed the period of social transition, so that they are much less aggressive, their social classes are much more stable, and their ambitions for development are much smaller. Therefore, on the whole, the greatest threat is still Tibet, a country that is in a period of social transition. Jingwen said.

Li Shimin was finally scared, because he was afraid that the Tang Dynasty would experience a period of decline in the army's combat effectiveness in the future, which could be said to be unavoidable. Li Shimin can also know from history that the army was often the strongest in combat effectiveness during the founding of the People's Republic of China, but later it declined. This is due to the lack of aggressiveness of the army, because the class of the country has stabilized, and it is difficult for the army to gain a channel for rising through the war. In this way, it is inevitable that we will be depressed in peace.

But the Tibetan threat is enormous, and they are in a period of social transition, a process that may last for decades or even centuries. But the next few decades will be the beginning of the decline of the Tang army. Of course, Li Shimin has to be careful, when he is weak, it is the time when Tubo is the strongest, so what will be the consequences? Strangling potential enemies in the cradle is something any giant would do. Do you have to wait for the enemy to grow up and bear it? In terms of the management experience of later generations, it is the lowest cost to prevent it in advance. And if it is solved after the fact, it is the most costly and very painful. If we don't take advantage of the current time to strangle Tibet, will it be too late when the Tubo Tongguò society transforms and grows?

It can be said that Li Shimin is now really attaching importance to Tibet and regards it as his biggest enemy. (To be continued......)
