"With righteousness, with oddity, where does this sentence come from?" Li Junxian asked Li Chengqian.

"Master, this sentence comes from Sun Tzu's Art of War." Li Chengqian replied.

Li Junxian could see that Li Chengqian was still relatively familiar with Sun Tzu's Art of War, and he was able to answer it if he said it casually.

"And what does that mean?" Li Junxian asked again.

Li Chengqian replied; The meaning of this sentence is to fight the enemy with upright strength, and then rely on ingenuity to win. Therefore, Sun Tzu also pays attention to winning by strategy. Li Chengqian still stubbornly thought that Sun Tzu also advocated victory by strategy, so he still replied like this, which made Li Junxian have a headache.

"Prince, you can't take it out of context! Sun Tzu did say that it was necessary to rely on ingenuity to win, but this must also be a clear prerequisite. He was interested in a clever plan to achieve victory, and the condition was to be in harmony. Zheng, that is, the strength of the upright, can fight the enemy with the enemy in a dignified manner. Sun Tzu's meaning is that if the strength of the two sides is not far apart, then you must use your upright strength to deal with the enemy, and rely on your own ingenuity to win. This is only possible when the strength of both sides is the same, but it doesn't mean that you will win with a clever plan for a while! Li Junxian said.

"Prince, I want to tell you one thing, in the face of absolute strength, any conspiracy is useless. As long as you are strong, you will be invincible first, and the enemy will not be able to defeat you. The enemy defeats you, and at most loses something. But if you defeat the weak with your strength, the weak will perish completely. Li Junxian said.

"But ......," Li Chengqian still wanted to refute.

"Nothing! If you still think that war depends on strategy, then look at the nomads. How many of the nomads of the steppe are literate, how many have learned the art of war? However, when the Wuhu was chaotic, didn't they all defeat those who had learned the art of war since childhood in the Central Plains? What is the reason for this? Li Junxian asked again.

Hearing Li Junxian talk about Wuhu Chaohua, this Li Chengqian had nothing to say. How many of those steppe peoples have studied the art of war? But in the end, the Han people were beaten everywhere. Even the Han people almost perished. Could it be that the people of those steppe nomads have a better art of war than the Han people? Is the strategy higher than that of the Han Chinese? They came and went with just a few tricks, relying on cavalry to attack the Han infantry from the front, and at most sometimes attacking from the side. But these few tricks gave the Han people a headache.

"That's their soldiers!" Li Chengqian finally reluctantly admitted.

"Yes. Soldiers are powerful, but soldiers are the core of national strength. They have cavalry, but the strength of the cavalry is not something that our infantry can resist. Cavalry has a natural restraint effect on infantry, and before the invention of my triad shooting, infantry simply could not restrain cavalry. However, my three-fold shooting can only deal with light cavalry, and if the enemy is heavy cavalry, there is nothing we can do. And even if we defeat the enemy, we will not be able to pursue it with infantry alone, and we will still have to rely on cavalry to pick up the pieces. So, this is strength. The strength of the infantry of the cavalry. Although some famous generals may have relied on infantry to use the terrain to restrain cavalry for a while, the infantry could not defeat the cavalry, which was the iron law of that era. Although they may have won some victories by some small means, but they have the next defense, can the infantry defeat them in those ways? Li Junxian asked.

"Teacher. I was wrong, I put the cart before the horse. The real war depends on the collision of strengths, not on any resourcefulness. The so-called resourcefulness is completely vulnerable in the face of absolute strength. Although it is possible to win for a while, it will be defeated in the end. This is the general trend, the general trend that Sun Tzu said. No wonder my father said that you are a famous general that is rare in a thousand years. That's how it works. Li Chengqian said.

Li Chengqian, he is just a child at the moment, and he can't refute Li Junxian yet. Moreover, the heavy strategy and light force are also misunderstood by those history books, so that ancient and future generations are man-made strategy is the foundation for victory. Now that he corrects his thoughts, it will be of great benefit to him in the future. But Li Junxian didn't expect that Li Shimin actually praised himself as a famous general who is difficult to achieve in a thousand years. This is a bit of an exaggeration.

"Prince, let me explain one more sentence to you, that is, those who are good at fighting have no outstanding achievements. This sentence is to say that a person who can really fight will nip all threats in the bud and will not let them develop. Those who are threatened. I don't dare to provoke you at all, so where do you come from! Suppressing the enemy with absolute strength is the essence of the unremarkable feats of a good fighter. ”

The crown prince Li Chengqian still doesn't understand, but Li Shimin next to him has completely understood. This is the difference between Li Junxian and other generals, other generals are all about strategy, how can they rely on strategy to win in the war. Li Junxian explained a higher-level strategy, involving the strategy of the whole country. Those who really fight wars will always only hover at the level of tactical battles, and cannot rise to the level of strategy.

The strength explained by Li Junxian is actually the strength of the whole country. As long as the strength of the whole country develops, then others will not bully you. If you have a strong army that is the best in the world, then where can other countries have the audacity to bully you?

If other generals explain the pure art of war, then Li Junxian explains the way of government, or even the way of kingship. If you are a general, then it is enough to learn the art of war and strategy. But as an emperor, he just learned the art of war, which was not enough to rule a country. The strength that Li Junxian said is many times higher than other art of war, and it has achieved the role of being able to guide a country's strategic thinking. Li Junxian used ordinary language and living examples to prove that only when a country's strength has developed can it be afraid of war.

If Li Chengqian still maintained the idea of wanting to win by strategy, then he would not be able to be an emperor in his life, and he could only be a general or a strategist. The emperor needs integrity, not intrigues. Li Junxian just explained this, paying attention to winning with national strength, which is in line with what an emperor should learn.

"It seems that I have found the right person to teach the prince Jun Xian!" Li Shimin thought secretly.
