"Jun Xian, you can say a few words!" Li Shimin said.

"What to talk about now?" Li Junxian asked in surprise.

Li Shimin nodded and said; "Yes! Tell me now, whatever comes to mind, you can talk about it. I asked you to teach the prince the art of war, so you talk about it first, I see how you speak? ”

Li Junxian wanted to cry without tears, this Li Shimin actually wanted to listen to Li Junxian's trial lecture. In later generations, many teachers had to listen to the trial lectures by the school leaders before joining the school, so as to judge whether they were qualified for the position of a teacher. And now, although Li Shimin asked Li Junxian to explain the art of war to the prince, he also had to listen to what Li Junxian was talking about. Li Shimin's approach is reasonable even in later generations. But Li Junxian had a headache, because his level of military art was very poor, and he liked to watch some miscellaneous books, movies and television dramas everywhere, so he learned the means of war. He is not systematic, so if he is directly in front of Li Shimin, a military scientist, he will immediately expose his stuff. Once the stuffing is revealed, Li Shimin's attitude towards Li Junxian may be greatly reduced.

"Forget it, let's go hard! Look how I'm fooling. Li Junxian thought secretly.

Li Junxian first asked Li Chengqian and the three of them: "Princes, before I explain the art of war to you, I want to ask you, why is there an art of war?" Why do we need the art of war? ”

"Because of the war!" "Because of the war!" "Because you want to kill the enemy!"

The three little princes also gave answers, and Li Junxian was quite satisfied. And Li Shimin also nodded to his son, which can be regarded as encouragement.

Li Junxian then asked: "You also said that the role of the art of war is to fight and kill the enemy. But since we are fighting for war, we must first understand what war is. If we don't understand what war is, then all our wars are meaningless. ”

This question, not to mention a few Xiao Zhengtai, even Li Shimin is in a daze. War, as easy a word it may seem, is rarely able to make sense of it. Since ancient times, many military strategists have not given a definition of war, and there are very few people who can make such a definition. And Sun Wu, known as the saint of soldiers, does not seem to have a definition of war in his "Art of War", nor does he make an explanation of war. Although Sun Wu's art of war covers strategy and tactics, it does not explain the essence of war.

"Jun Xian, what is war?" Li Shimin actually took the initiative to ask.

Li Junxian bowed to Li Shimin and said, "Your Majesty, war is actually fighting!" It's just that war is made up of a series of fights with a large number of people. ”

"It's as simple as that?" Li Shimin seemed a little surprised by this answer.

"Your Majesty, since our China came from the era of Ru Mao drinking blood, which war was not a struggle? Even though the weapons we use have changed, from the primitive sticks to the current spears and knives, in fact, the weapons we use to kill people are better, but the essence of fighting has not changed. Even, in the future, no matter how advanced our weapons are, we may one day be able to kill people thousands of miles away, but the purpose of fighting still remains the same. Li Junxian said.

"Killing people thousands of miles away, that's a fairy! We mortals can't do it. Li Shimin sighed.

Li Junxian will not explain the statement that any missiles can kill people thousands of miles away. Anyway, it was useless to explain, but it made Li Shimin uneasy.

"However, although war is a series of struggles, I will next talk about the meaning of our struggles!" Li Junxian said.

This time, not only the three little kids, but even Li Shimin pricked up his ears to listen. For Li Shimin, the art of war they learned only talked about how to kill the enemy with higher efficiency, but it did not make the essence of war. Li Junxian's words seemed to have opened a window for Li Shimin, and Li Shimin's thoughts suddenly became clear. Li Shimin has a feeling that Li Junxian's understanding of war far surpasses him, and even far exceeds anyone else in the world.

"There is no love for no reason in this world, there is no hate for no reason, and naturally there is no war for no reason. From the fight between two gangsters to the battle between the armies of two countries, it is actually a process of using force to impose one's own ideas and wills on each other. Li Junxian explained.

The three little boys were still a little confused, but Li Shimin already understood. Li Shimin felt suddenly enlightened, and he finally understood the essence of the war. Although wars have been fought in this way before, no one has been able to sum up the essence of wars. Even Li Shimin, although he used to fight to kill the enemy, he heard for the first time that war was a method of imposing his will on the enemy.

Li Shimin was also a military strategist, and he quickly thought of a time when the wars since ancient times had not been like this. There are some things that cannot be reconciled at the negotiating table, and cannot be obtained from the negotiating table, then it can only be through war. This is the means of imposing one's own will on the other side. Don't talk about it far away, let's talk about the chaotic times at the end of the Sui Dynasty. The reason why the peasant rebels went to war was to impose on the court the will of the peasants to live a happy life. And the suppression of the imperial court is to impose its will to exploit the people on the people.

Then those princes who took advantage of the chaos to understand even more clearly that they wanted to be emperors and achieve hegemony. But why did the other princes let you be emperors, then they had to fight each other. Until the end, when no one can resist you, that's when you win and become emperor. Li Yuan got mixed to the end, so Li Yuan was the founding emperor of the Tang Dynasty.

"Jun Xian, that's a good point, go on!" Li Shimin said.

Li Junxian finally breathed a sigh of relief, and he finally got over it. Li Junxian just relied on the miscellaneous theories he learned in his previous life, but now he can fool Li Shimin, and Li Shimin even recognized him to give lectures to several princes, isn't this a success? In the future, as long as you rely on some of your own war theories of later generations, am you afraid that you will not be able to be qualified for the position of the prince's art of war teacher?

And now, Li Junxian looked at Li Shimin with some amusement. It stands to reason that since Li Shimin has approved it, he should also handle official business, but he is still listening here. Li Junxian also saw that Li Shimin wanted to take the opportunity to listen to Li Junxian's lecture, but he couldn't pull his face down and say it directly. But now Li Shimin has called a eunuch to be responsible for recording on the side! This is the process that Li Shimin is also learning.
