"Wanrou, Lizhi, your grades seem to be very poor these days? I've been teaching you art classes for the last few days, so where have you listened? Shi Bufan asked.

And Li Wanrou and Li Lizhen glanced at each other, and then showed a look of fear. These two little girls who haven't even reached Lori's age are still very afraid of Shi Bufan, a teacher, after all, in the eyes of the ancients, the teacher is equivalent to her father, so of course they don't dare to mess around.

"Shi Xiao Shulang, we haven't listened carefully lately, so we ......," Li Wanrou wanted to explain.

Shi Bufan immediately said: "Hmph, is it really not too careful?" I don't think you're listening! You don't have the heart to study art at all, but you go to other classes. You've actually become a class party? ”

As a veteran class-rubbing party, can Shi Bufan not know that this Li Wanrou and Li Lizhen haven't been listening to the art courses they explain at all these days? According to the extraordinary arrangement, in the past few days, Li Wanrou and Li Lizhen, a group of little girls, have been arranged to teach art, but the other little girls have good grades, but Li Wanrou and Li Lizhen's grades have not improved. In this way, Shi Bufan is very skeptical, because according to Shi Bufan's memory, Li Lizhen, the princess of Changle, is still quite accomplished in art and Chinese painting, and even the famous painter Yan Liben has praised it. So she should be talented in this area, and other girls may not have this talent, so it's understandable that her grades are poor. But Li Lizhen, a talented person, still has such poor grades, which means that she is not studying seriously at all.

After about two days of observation, Shi Bufan found that the two girls were not listening carefully to the so-called art course, but were using their minds to the class. They went to those art of war courses, and they didn't study art seriously at all.

Li Wanrou immediately smiled reluctantly: "Shixiao Shulang, we are really not familiar with these art and painting courses!" ”

"Good! Since you are not honest, then I will also go and talk to the prince and the king of Qin, and see if their discipline is broken, and actually let you two little girls come to class? If they want to learn the art of war, they can directly ask me for teaching records, why use this method to use a little girl to learn the art of war? Shi Bufan said.

Li Lizhi said embarrassedly: "Shixiao Shulang, you know? ”

"Nonsense, since ancient times, how many six-year-old girls will love to learn the art of war? If I didn't know that there was someone behind it, then I wouldn't be worthy of being your teacher! You'd better be honest, honestly still a good boy. Shi Bufan said.

Soon, Li Wanrou and Li Lizhen finally explained honestly, in fact, this time it was the crown prince Li Jiancheng and the king of Qin Li Shimin who had the same idea, they were very curious about Li Jingdu's lecture to listen to Shi Bufan's lecture, so they wanted to hear what Shi Bufan's art of war was. And after all, they are the crown prince and the king of Qin, so naturally they can't pull their faces to listen to the class. So I can only let my two daughters listen here, and then go back to explain what they heard to their father. And after a few days of Shi Bufan's explanation of the war game deduction, Li Jiancheng and Li Shimin felt very useful, so they let their daughter continue to listen. But they didn't expect that they would be exposed so early?

"Ouch, the prince and King Qin's discipline is shattered, and even his six-year-old daughter is used as a spy?" Shi Bufan complained.

Shi Bufan immediately took over two books, and then said: "This is my teaching file on the art of war, you can take it to the prince and the king of Qin, you will study hard in the future, don't do this kind of casual thing." After all, you are two little girls, and the art of war is not something you should learn at your age. If you can grow up, if you are really interested in the art of war, I can teach you. Now, though, your mission is to learn art well, understand? ”

"Got it!" Li Wanrou and Li Li nodded and said.

Li Lizhi took this teaching file on the art of war and gave it to Li Shimin, saying: "Father, I was discovered by Shi Xiaoshulang, and he gave me this, which is the archival record of all his teaching!" ”

After Li Shimin heard this, he immediately became excited, because didn't he just want this? But he really couldn't pull his face to keep up with Shi Bufan, so he had to let his daughter come to investigate.

"What did Shi Bufan say?" Li Shimin asked.

Li Lizhi said: "He said that his father and the prince's uncle broke the ground, and he actually used his six-year-old daughter to do this kind of thing!" ”

Li Shimin's old face turned red, this thing was indeed not authentic for him. No matter how a father is, he actually uses his daughter who is less than six years old to do things, how does it feel as if the festival is all broken? Even if you want to "sell" your daughter, you have to let your daughter grow up and "sell" again! A six-year-old girl, you are still using it as a father, so it is really not good to spread your reputation like this. Not to mention the biological father, even if a stranger uses a six-year-old girl as a spy, it is very immoral. This thing is what he did not be authentic, and he was sarcastically ridiculed by Shi Bufan, and he deserved it.

However, after all, Li Shimin is a guy who can be the emperor in the future, and the thickness of his face is naturally not something that ordinary people can imagine. He just blushed a little, and then quickly recovered, as if he hadn't heard Shi Bufan's sarcastic words.

Li Shimin took the teaching file and came to the conference room of Tiance Mansion. And if it were ordinary people, they would not have thought that this Tiance Mansion conference room had changed. It's all maps, and these maps have grids on them, and there are soldier models on them. There are infantry, cavalry, etc., and there are even some special classes.

Obviously, this Tiance Mansion conference room has been turned into a place for war games. Since Li Shimin heard about wargame deduction, he also changed his conference room into a place for wargame deduction, preparing to exercise the ability of generals, and conduct a series of wargame deductions, and then learn from the experience. And Li Shimin found that through these war games, his generals grew rapidly. Let them deduce each other, the generals under them have made rapid progress, and even they have found the aspects where they are lacking in the use of troops.

"King Qin, this war game deduction is too good. Although it is not a real battle, it can also train soldiers very well. And in this way, they will definitely be able to grow rapidly, so that when they are fighting, they can die a lot less! Fang Xuanling said.

Li Shimin looked at this war game, and then said: "It's really a great creation!" With this war game, I don't know how many soldiers will die in the future! ”

Of course, Li Shimin knows the importance of this wargame deduction, and this wargame deduction is definitely a very useful invention, especially for the training of the army, especially for the training of officers, which has incomparable advantages. Moreover, this wargame can be used from a squad of dozens of people to a large-scale battle of tens of thousands and hundreds of thousands. In short, it can be used by the army at the executive level, and it has a very huge reference value for this training.

Of course, even if you don't need to say it from time to time, Li Shimin knows that this can only be used for reference, not as an absolute result. Because the stakes on the battlefield are so great, you can't just do that. However, is it not enough to refer to it? It's better to have a reference than to have no reference at all! In the past, in wars, generals could only be tempered through actual battles, but the cost of such a result was too great, and Li Shimin also understood very well the pain of success and withering bones. If Li Shimin was a simple general, he would naturally not care about this. But his goal is to be the monarch of an empire, and as a monarch is no longer a general, but a politician. A military strategist may simply care about how to defeat the enemy and make himself pay a lot less. And politicians have to consider the cost of this war, especially the family of every fallen soldier, and once a soldier dies, it is equivalent to one less labor force for the country, one less tax for the imperial court, and an increase in the cost of supporting the families of the soldiers.

Therefore, politicians consider things at a much higher level than military strategists, so Li Shimin's consideration is no longer purely military issues. And this war game deduction is obviously able to train generals and avoid casualties among many soldiers. If you can let the generals do many sand table exercises before going to the battlefield, it will definitely reduce the casualties of many people. With this set of wargame deduction mode, it has great benefits for future military development, so that generals can have a sufficient foundation before the official battlefield, and can even conduct deduction before the war, as much as possible to find loopholes, to avoid being taken advantage of by the enemy.

"King Qin, but we haven't figured out how this Shi Bufan judged the casualties! You know, we don't have much to do with our judgment of casualties. For example, the difference between elite and non-elite, how do we judge the proportion of their casualties. You see, General Qin thinks that his soldiers are more elite and should be able to defeat General Cheng, because General Cheng's soldiers are relatively poor. However, General Cheng had twice as many soldiers and horses as General Qin, so he should be able to defeat them. Both sides say that the public is reasonable, and the mother says that the mother is reasonable, may I ask the King of Qin, how should it be adjudicated? In the past, the county lord did not know how to determine the combat effectiveness, how should we judge? One of the generals asked.

Li Shimin opened Shi Bufan's lesson plan, and then saw the chapter on the referee's ruling, and then said: "Equation? Using arithmetic methods to deduce war? ”

After a while, Li Shimin shouted: "Wonderful, really wonderful." In the past, we didn't think about using arithmetic methods to deduce the process of combat casualties. If it is measured by comprehensive combat effectiveness, it is easier for the side with more numbers to win? This arithmetic equation is amazing! ”

Li Shimin saw the equation provided by Shi Bufan, and felt really shocked. Because this equation can be said to deduce the casualty trend when the army fights, so that it is relatively easy to deduce the casualty process. And this equation is actually used by Shi Bufan using the Lanchester equation of later generations. The Lanchester equation of later generations is very useful, especially in local battlefields, which has a very important reference significance. Although it is not strategically useful, the tactical confrontation is definitely worth considering.

"It turns out that this is the same thing about our interspersed division tactics in the past. Didn't we all say this in the past, but there was no basis for it at all? But now, I have finally found a basis for this arithmetic! ”

Li Shimin finally found his past experience in using troops in this later Lanchester equation, and many generals in the past also knew that they should cut and intersperse into the enemy's formation, and then they could form a local superiority in troops. And this Lanchester equation is actually a mathematical explanation of the scientific principle of doing more with less in the past. In the vast majority of cases, less wins more than by cutting and then cutting the enemy's army into two parts that cannot be connected with each other. Finally, a local force advantage is formed, and then the process of depletion of troops can be deduced by following the method in this Lanchester equation.

This method, even if Sun Wu used 50,000 troops to defeat the enemy of 200,000 back then, he actually used this method. It is nothing more than the use of the principle of this Lanchester equation to form a local superiority in troops, which can destroy the enemy at a relatively low cost, and eat the last piece by piece.

However, Sun Tzu's Art of War was not able to give a reasonable explanation, although many generals also understood the truth of cutting the enemy, but they all knew it but did not know why. I just know how to use it, but I don't know the principle of it, even Li Shimin is like this.

As for why Shi Bufan knows this mathematics, it is because this mathematics is not difficult, that is, the high school level of later generations. Although Shi Bufan majored in liberal arts, it doesn't mean that he can't do mathematics! Shi Bufan has a master's degree in economics, and although he is not a professional mathematics scholar, he is definitely not bad. People who are not good at math will not be much better at economics. What's more, this is only high school-level mathematics, if Shi Bufan can't pass it, then he won't be able to get more than a dozen degrees!

"Shi Bu is extraordinary, and he will definitely be able to become a soldier saint no less than Sun Wu in the future! And the future generations of generals of my Datang will always benefit from his wargame deduction and equations. His contribution is definitely no less than that of Sun Tzu, just this wargame deduction and equation, absolutely not having to be a grandson. If he can write a book of the art of war in the future, then maybe he will be able to truly become as famous as his grandson! It seems that this time it was the lonely king who earned it, and it seems that he must give him some benefits in the future, and don't let him take refuge in the eldest brother. Li Shimin said.
