"Emperor, Tubo was just a primitive society before the current Zanpu Songzan took office. They were the same as our two Emperors of Yan and Huang. But after Zanpu came to power, they began to transform into the slave era. And the emperor, you should know that in each era, the country will burst out with great combat power. Because wealth, interests, and glory will be obtained during this transformation period. This transformation period can actually make many people go from a worthless person to a tribal leader, or even a rich person. At that time, Xia Qi attacked foreign races and made his family the world. In order to gain benefits, the military officials of that period fought bravely, just to obtain land, slaves, and then live a wealthy life."

"Later, we will explain it by Shang Yang's reform period. During Shang Yang's reform period, the soldiers fought bravely to gain titles and land of their own, and they burst out with great combat power. So, the emperor, you see, this is actually the embodiment of combat power. In this social transformation period, the entire country is very aggressive. During the social transformation period, they will start to expand one after another, making their land slaves richer. Therefore, in the future, Tubo will undergo a social transformation, and they will burst out with very powerful combat power and full of aggressiveness."

Li Shimin thought about it carefully and found that this was indeed a problem. Tubo was originally a primitive society, but now it has been reflected in a slave society. This is actually a social transformation. In order to gain wealth, their combat effectiveness, soldiers and soldiers will support the expansion in order to gain honor, and even for profit. The army is also the time when the combat effectiveness explodes, and the marriage kinship alone cannot suppress their expansion. Only Li Shimin then realized how stupid it was to rely on marriage kinship to appease Tubo at the beginning. Sooner or later, they will expand, and it is not something that can be solved by marrying a princess.

Li Shimin then asked curiously: "We in China have completed these two transformation periods. It took a thousand or two years, but why did Tubo go through so quickly? Also, after you said this, I probably understand that the reason why those grassland nations can burst out with such strong strength is actually experiencing social transformation, so that they can constantly oppress us. Once the social transformation is completed, they will be worse than us. But why did China have been in China for so long, but they are so fast?"

Jing Wen could only helplessly explain to Li Shimin what latecomer advantage is. The so-called latecomer advantage is actually through the experience and lessons of his predecessors, so that he can reach the level of his predecessors as soon as possible in a short period of time. Just like the first person who ran off the country, he often had to be responsible for exploring the way and encountered many dangers. The person who followed him saw that his predecessors encountered dangers, so he could deal with it quickly. Moreover, they also had the experience of his predecessors and could quickly chase them. Even they could also take shortcuts, which was a huge cheating tool.

Those other nations can only learn Chinese civilization and learn Chinese civilization's experiences and lessons, and then they can complete the journey that China has only taken for thousands of years in just a short period of time. This is actually the influence of Chinese civilization, which allows them to quickly complete this path and burst into a large amount of combat power, so they invade China in turn. However, China had no civilization to refer to, and naturally the process was very slow. However, those nomadic peoples, etc., could refer to Chinese civilization, so they quickly carried out internal social reforms. It can be said that everything was influenced by China. Then they came to invade China again. China had already gone through the period of social transformation, and its combat effectiveness naturally declined.

"Your Majesty, our Tang Dynasty has just founded. It can be said that it is the most powerful period of combat effectiveness. But how long can this period last? Although we can have firearms and many advanced troops, how long can these last? Therefore, we may not be ahead of them. They can continue to learn from us in this process. And they will probably be in this so-called social transformation period for hundreds of years in the future, but our China will live for a long time because of the peaceful days, and the army is not aggressive and will eventually become depressed. But at this time, the Tubo people are the most aggressive, and their ambitions can be said to be unsatisfied. They face our weakest with the strongest strength. What will happen to us?"

"So, I think Tubo is the most threatening. The surrounding countries, whether it is the Turks, Tuyuhun, or even the Indians in the south, have passed the social transformation period, so their aggressiveness is much smaller, their social class is much more stable, and their ambitions for development are much smaller. So, overall, the most threatening is Tubo, a country that is in the social transformation period." Jing Wen said.

Li Shimin was finally scared because his Tang Dynasty might experience a period of decline in combat effectiveness in the future, which can be said to be inevitable. Li Shimin can also know from history that the army often has the strongest combat effectiveness during the founding period, and then declined. This is caused by the lack of aggressiveness of the army, because the country's class has been stable, and it is difficult for the army to gain channels for growth through war. In this way, it is inevitable that it will be depressed in peace.

But the threat of Tubo is huge. They are in a period of social transformation, and this process may last for decades or hundreds of years. But the next few decades will be the beginning of the decline of the Tang army. Li Shimin must be careful. When he is weak, it is the time when Tubo is the most powerful. What consequences will this have? Thorning the potential enemy in the cradle is something that any giant owl will do. Can you still wait for the enemy to grow up and bear it? In terms of management experience in later generations, pre-prevention is the lowest cost. If you solve it later, the cost will be the highest and very painful. If you don’t kill Tubo now, will you have to wait for Tubo to grow through social transformation, which is too late.

It can be said that Li Shimin is now truly paying attention to Tubo and regards Tubo as his biggest enemy. (To be continued, please search for Astronomy, novels are better, updated and faster!
