A large sand pond was newly opened in the back garden of the Lady of Qin's house, which Wang Yuan asked Liu Jun to build before going to Beihai County, and its purpose was to build a sand table for drills when learning the art of war.

Wang Yuan was not proficient in marching and fighting, but after initially promising Liu Jun to teach him the art of war, Wang Yuan spent most of his time in the Hanlin Academy temporarily studying the military books on the ancient bookshelf. I often study in the morning and teach Liu Jun in the afternoon.

Liu Jun has a great interest in learning the art of war, and seems to have some talent, asking more questions than a child of his age should ask. At first, Wang Yuan thought that he only needed a simple answer, but later found that he had to really explain these questions in order to let Liu Jun feel relieved, and he also needed to study the art of war more deeply, and it would not work to be hastily perfunctory.

So, in the back garden of the Lady of Qin's mansion, such a sand pond was opened, and several ponds were dug around. In this way, it is possible to simulate the terrain in the tactics described in each art of war. Where are the mountains and valleys, where the water is crisscrossed, where the desert wilderness and so on. Terrain simulation and deduction is a method that will be adopted by later generations of armies, which is intuitive and effective. Although it was much easier to teach Liu Jun, Wang Yuan himself also realized many truths that he couldn't understand when he was reading.

Under the sun, Wang Yuan and Liu Jun wore straw hats on their heads and stood barefoot side by side by the sand pool. The two of them each held a small flag in their hands, pointing at the terrain and sand in front of them, and bent down from time to time to plant a small flag.

Not far away, Mrs. Qin Guo took Zi Yun'er and Qing Yun'er to sit in the shade of the tree and chat, and the three pairs of beautiful eyes glanced at the sweaty master and apprentice who were busy in the sun from time to time, with smiles in their eyes.

This time the simulation is the battle of Pengcheng when Chu and Han were fighting, and the person Liu Jun admires the most is Xiang Yu, the overlord of Chu.

After planting all the red and blue flags in his hand on the ground, Wang Yuan smiled and said, "Liu Jun, how do you feel when you come to see the comparison of the military strength of the two armies of Chu and Han?" ”

Liu Jun was stunned and looked at the dense red flags and few blue flags everywhere and scratched his head and said: "Teacher, this strength is too disparity, the strength of the Han army is several times greater than that of the Chu army...... No...... Dozens of times better, how can this be played? ”

Wang Yuan smiled and said: "Yes, in history, Liu Bang united with other princes' soldiers and horses, with a total strength of up to 560,000, while Xiang Yu's strength was only 30,000, this is a big battle with a huge disparity in strength." And at that time, Xiang Yu's soldiers and horses were in the process of cutting down, and they were raided into Chu by the Liu Confederation coalition army from the belly and back, which was a must-lose battle in the eyes of ordinary people. But this was not the case, Xiang Yu dispatched 30,000 soldiers and horses to meet the battle, not only won the battle, but also almost completely annihilated the 560,000 Han army. If it weren't for that, you'd think I'm joking. ”

Liu Jun's face was dumbfounded, and he muttered: "It's really unbelievable that you actually won and annihilated all your opponents." How did Xiang Yu do it? ”

Wang Yuan held a long bamboo pole and began to point on the terrain of the sand table, under his guidance, Liu Jun did not lean over and pull out the flag, half an hour later, there was only one red Han army flag left on the sand table, and it was far away from the battlefield. That is already a sign that Liu Bang is fleeing alone.

Liu Jun's excited little face was flushed, listening to Wang Yuan's narration of one elusive battle after another, one incredible victory after another, and his small body was also full of blood.

"Teacher, I don't understand why Xiang Yu has won consecutive battles, I know that he is a big hero, but after all, there is a huge disparity in strength, as the saying goes, one punch is hard to defeat four hands, and a hero can't stand up to many people."

Wang Yuan wiped his head and said: "This is the point I want to say, there must be a reason for everything, and we have learned these reasons in the previous books that teach the art of war." First, the more soldiers the better, but the better the better. The so-called soldiers are not expensive, but the fine is focused, and the most are scattered and undisciplined, and it is difficult to restrain them. If the leader of the army is incompetent, no matter how many soldiers and horses there are, it will be a rabble. ”

Liu Jun nodded slightly and said, "That's what it says in that book "The Art of War". ”

Wang Yuan nodded and said: "In this battle, we can find that Xiang Yu's 30,000 Chu troops are elite soldiers and strong generals who have followed him for many years, and they have the same heart to mind, strict military discipline, and rich combat experience, this is a real elite soldier." And Liu Bang's coalition army, although there are 560,000 people, is the combined army of the five princes. At the beginning of the war, the five princes were already unhappy with each other over the division of land and property, and if it wasn't for Liu Bang's suppression, they would not have been able to unite to attack Chu together. The five princes had their own selfish intentions, each preserved its strength, and only sent a small number of elites, and most of the rest were old and weak soldiers. Among the 560,000 soldiers and horses, the most that can really be counted as elite soldiers is 100,000, and the rest can be called a rabble. ”

Liu Jun nodded slowly and said, "I see." ”

"Moreover, these 560,000 coalition troops are difficult to form a unified command and deployment due to their different affiliations and different military systems, which is also a common problem of the coalition army, which greatly weakens the combat strength of the coalition army." Wang Yuan added.

"Teacher, I understand, but even so, there is still a huge disparity in strength, and the rabble is not completely incapacitated. Even those 100,000 elite soldiers are several times that of Xiang Yu's soldiers and horses. Liu Jun frowned.

Wang Yuan smiled: "Of course, it's not just this reason. As far as the types of troops are concerned, the 30,000 soldiers and horses led by Xiang Yu are not only elite, but all cavalry. The Art of War: The soldiers are fast. The mobility of cavalry is dozens of times superior to that of infantry. But when I told you about the battle process just now, did you notice that after Xiang Yu's advanced army Lu Jianqiu defeated Fan Hao and other troops, he immediately moved to Huling to Xiao County to take an encirclement and blitzkrieg. These two places gathered more than 100 miles, and after defeating the Fan Hao army in the evening, they arrived at Huling in Xiao County in the middle of the night, if it wasn't for cavalry, how could they do it? After the soldiers and horses of Huling in Xiao County were attacked by Xiang Yu, Cao Shen Zhou Bo pulled out the army overnight to rescue, and Xiang Yu had already escaped with a great victory when he arrived, which was the power of cavalry maneuvering. ”

Liu Jun was leisurely fascinated, with a look of reverence on his face.

"The third reason is that there are clouds in Sun Bin's art of war: time, place, and people, the three are not allowed, although there is victory and disaster. In this battle, Liu Bang took advantage of Xiang Yu's attack on Qi and attacked on his back, and when Xiang Yu fought back, Chu Di had already fallen into the hands of the coalition army. However, Chu is the place where Xiang Yu has a foothold, and this battle is carried out in the land of Chu, and Xiang Yu knows the terrain, mountains, rivers and cities well, which is the advantage of the location. The people of Chu supported Xiang Yu, and everywhere they went, they served clear water, grain and grass with the Chu army, reported the dynamics of the coalition army, and spontaneously destroyed roads and bridges, and destroyed mountain roads and cities. And Xiang Yu's soldiers and horses have grown up in Chudi, and they are obviously more adaptable to cold and warm weather. ”

Liu Jun clapped his hands and said: "The teacher's analysis is wonderful, and the students are suddenly open, but can the students add one." ”

Wang Yuan smiled and said, "Which one?" ”

Liu Jun straightened his chest and said: "Another reason is that it is Xiang Yu's soldiers and horses, the overlord of Chu is strong to cover the world, he is one enemy and a thousand on the battlefield, and the Han army is afraid that his legs will be weak when they see him." ”

Wang Yuan laughed and said: "This can be added, the main general is brave, and martial arts are indeed a factor." The determination of the commander determines the determination of the soldier, the commander is brave, and there is no soldier who is not brave. ”

Liu Jun also laughed, and the master and apprentice laughed at each other, very happy. A maidservant girl came from under the shade of the tree, and came to the sand pool, and while carrying her skirt to avoid the muddy water stains flowing on the ground, she saluted and said: "Master Wang, Madame invites you and the young master to go to the shade of the tree to drink saliva and rest, saying that the sun is strange and sunny." ”

Wang Yuan smiled and nodded: "Got it, Liu Jun, go and take a rest." ”

Liu Jun arched his hand and said: "Teacher, let's go and take a break, and the students will think about the process of this battle again and ponder carefully." ”

Wang Yuan was very satisfied with Liu Jun's studious and researching attitude, and immediately washed his hands and put on his shoes and walked to the shade of the tree. Mrs. Qin Guo stood up with a smile, and Qingyun'er hurriedly poured a cup of tea.

"Wipe your sweat." Mrs. Qin Guo handed over a white silk scarf, her eyes full of honey.

Wang Yuan thanked him, wiped the sweat from his face, sat on the chair, and picked up the teacup to drink.

"Jun'er has really changed a lot, it's rare for you to fall in love with him like this, and the slave is very happy in his heart." Mrs. Qin Guo smiled.

Wang Yuan said: "I have a hunch that Liu Jun will become a great weapon in the future." A child of his age, born into a rich family, rarely has one who is not stubborn. But Liu Jun is interested in things beyond his peers, and he is thoughtful and courageous, and I really like him. ”

Mrs. Qin Guo was happy in her heart, but she said: "Don't praise him too much, lest he his tail." If Jun'er can become a talent, you will also make a lot of contributions. I want to thank you so much. ”

Wang Yuan smiled: "Madame has already thanked me, no need to thank me anymore." ”

Mrs. Qin Guo's face turned red and she took a sip. Qingyun'er and Ziyun'er blushed at the same time, they both understood what Wang Yuan said, Mrs. and Wang Yuan were fighting in the room that day, and the two of them were listening outside with red faces, and naturally knew that the relationship between Mrs. and Wang Yuan was no longer ordinary.

Mrs. Qin Guo coughed twice to cover up the past, and said softly: "Cousin Shicai sent someone to find you and asked you to go to his mansion to talk about things, and I didn't disturb you when I saw that you and Liu Jun were talking about Zhenghuan." ”

Wang Yuan got up and said, "Then I want to go to see Du Zhilang, it must be a matter of Li Shizhi and Pei Kuan's case." That's a big deal. ”

Mrs. Qin Guo hurriedly pulled his sleeve and said, "Don't panic, I asked my cousin to come to the mansion to talk in person, and I just want to listen to it." The cousin will arrive in a while, what are you in a hurry. ”

Before he could say anything, a maidservant girl hurriedly came from outside the hanging door, and after saluting, she reported crisply: "Yang Duzhilang is here, please let him in?" ”

Mrs. Qin Guo smiled: "Look, this is it, my cousin's feet are quite fast." Let him in. No one waited to retreat to the outside of the garden, and no one was allowed to come in. ”
