"Which one are you?"

"Xiaguan Xiahou Nan, my father is a township marquis of Gao'an."

Cao Wu raised his eyebrows: "Your father is Fubo General Xiahoudun?" ”

"Exactly."

"Then you'll have to call me uncle."

Cao Wu wanted to say more, but the young man said: "If you have ambitions, you don't look at your age, and you don't look at your seniority, please interpret the general, the advantage is mine, why should I lose?" ”

The Cao family's surname is Xiahou, and Xiahou is the family, Cao Wu didn't expect that there was such a stunned young man in the Xiahou family, it seemed that he had read a few military books, and he was empty-eyed.

But Cao Wu thought deeply. suddenly understood Xiahou Nan's reason for being here.

He looked out of the door for a while, and continued: "You said Sun Tzu's Art of War, and that Sun Tzu also said that if you have 100,000 divisions and go on expeditions for thousands of miles, you will not be able to do 700,000 things. It means that 100,000 soldiers need 700,000 people to support them. The name of our army is 800,000, and how many people can fight? 100,000, or 200,000? The tens of thousands of sergeants from Liu Biao and Liu Cong, can they really listen to your orders? Even if you listen to your orders, where can the 800,000 military horses be in formation? ”

Using the art of war against the art of war, Xiahou Nan was speechless for a while.

Cao Wu looked around and found that everyone was particularly puzzled, so he said: "Ah Jiu, go to the sand table, I and them will talk about the Yangtze River defense line." ”

Ah Jiu behind him agreed, and his fruitful figure turned, and after a while, he was lifted to a low table with a few maidservants.

The officials came around, and even Cao Cao in the curtain was very curious.

Cao Cao wanted to stand up, but after thinking for a while, he sat down again.

"It's ......"

Among the officials, Cui Yan subconsciously said: "This is the Yangtze River? ”

I saw that on the table, a topographic map made of mud and sand, there are mountains and rivers, and there are many marks on it, and the Yangtze River Basin, starting from Yizhou, Jingzhou, Yangzhou, and all the counties and counties through which the Yangtze River flows, are all marked.

At the end of the Eastern Han Dynasty, the ability to draw maps was already very strong, and there had been a simple tactical deduction sand table, but no one had ever seen Cao Wu so exquisite, with a sand table the size of a table, the terrain was high and low, and the mountains were undulating, which was very intuitive and convincing.

Sima Yi's eyes widened even more, and he couldn't take his eyes off the sand table.

Cao Wu glanced at him and said coldly: "The princes don't understand that this battle will be lost, because since the history of China, there has never been a battle of the Yangtze River. ”

He took a long pole from Ah Jiu and pointed to the sand table.

"Shang Dynasty Xia, Zhou Dynasty Shang, Qin King Sweep Liuhe, all in the north of the Yangtze River. Emperor Taizu Gao slashed the snake uprising, Han Xin leveled the world, and King Xiang did not cross Jiangdong. Emperor Shizu Guangwu completed it in 12 years, and he did not reach the south of the Yangtze River. Now Sun Quan occupies Jiangdong, and has gone through three generations, and the country is in danger and the people are attached. Today's battle is the first water battle on the Yangtze River. ”

Everyone listened attentively, and then realized that this was really the first large-scale water battle on the Yangtze River in history.

Kong Rong said disdainfully: "Jiangdong to the south is mountainous, barren land, can it be regarded as the first in history?" ”

"The land of fish and rice in the south of the Yangtze River is just not developed now. In the future, Jiangnan will be rich, far beyond your imagination, maybe any place in Chun Shenjun will become one of the best cities. ”

Everyone was noncommittal, and Cao Wu continued: "In the future, there will inevitably be more and more water battles on the Yangtze River, but the terrain on the north bank of the Yangtze River is undulating, and the battle of crossing the river will change from time to place. I have done many deductions, the north and the south are at war, and the north has lost three and won four. ”

What Cao Wu is talking about is the seven large-scale battles in the Yangtze River basin that he knows of in history.

The first battle of the Yangtze River was the Battle of Chibi, in which Sun and Liu's allied forces burned the company camp, plotted to break the enemy, and won in the south.

The second time was the battle of Jin to destroy Wu, the Western Jin army was divided into six routes, the Wu army crossed the river with iron cables, poor and useless, and the north won.

The third time was the Battle of Weishui, where Xie Shi and Xie Xuan's children broke the thief, so that the great plan of the former Qin Dynasty was wiped out and the south won.

The fourth time was the battle of Sui to destroy Chen, Yang Guang led the army to cross the river, and the Yangtze River defense line was leveled in 22 days, and the north won.

The fifth time was the Yuan Dynasty to destroy the Southern Song Dynasty, took the western front, attacked Xiangyang, and tried to enter Sichuan from the Diaoyu City, the Southern Song Dynasty watched alone for forty years, and was finally destroyed, the Han family died for the first time in the world, and the north won.

The sixth time was Zhu Yuanzhang's crusade against Chen Youliang, both of which were on the south bank of the Yangtze River, but in the end Zhu Yuanzhang crossed the Yangtze River, and the beggar emperor rebuilt China, and the south won.

The last time was in modern times, "Zhongshan was pale and yellow from wind and rain, and millions of heroes crossed the river", the front from Jiujiang in the west to Jiangyin in the east, in the sea of the people's war, was submerged like paper paste, and the north won.

Those who won in the north were all at the end of the southern dynasty.

Among them, although the battle of Weishui took place in the Huai River Basin, due to the reason that the river must be defended, the former Qin Fujian intended to be on the Yangtze River, which was actually counted as part of the battle of crossing the river. Others, like the Northern Song Dynasty and the Southern Tang Dynasty, were not included in this list because the strength of the defending naval army was too poor.

Since learning that Cao Cao sent troops to Jingzhou, Cao Wu has been studying this sand table every day, and he has quite a lot of experience.

As a keyboard warrior who can spray anything and a key political powerhouse who knows a little bit about everything, this is also a basic skill.

He pointed to various places in the plate with his long rod and circled a few dots.

"Because of the danger of mountains and rivers, crossing the Yangtze River from the north, there are actually only a few breakthroughs."

"From west to east, the first breakthrough is Hanzhong. The upper reaches of the Yangtze River flow through the country of Bashu Tianfu, and if you want to enter Bashu in the north, you must go to Hanzhong, because it is located at the junction of the Qinling Mountains, the Daba Mountains and the Kunlun Mountains. Among them, Jianmen Pass is in the south of Hanzhong, and the terrain is dangerous. Only by seizing Hanzhong and taking the Sword Gate can you have a chance to enter the country of abundance. ”

"The second breakthrough is Xiangyang. Xiangyang is the only passage between Daba Mountain, Wushan Mountain and Dabie Mountain, and south of Xiangyang is the open area of the Hanjiang River Plain. ”

"The third breakthrough is Hefei. This city is between Chaohu Lake and Dabie Mountain, and if you take Hefei, you can enter Moling and Jingkou in the east. ”

"The last breakthrough is Xuzhou, defending the river must defend Huai, Xuzhou's terrain is not dangerous, but it connects all parties, attacking the east in the west, conquering the south in the north, and entering Xuzhou. From Xuzhou to the east and then south, the plains are fertile, straight down to Yangzhou, and the lower reaches of the Yangtze River. ”

Among them, Moling is Nanjing, at this time Sun Quan has not moved to Moling, his station is still in Jingkou, that is, near the current Zhenjiang in Jiangsu.

Although everyone has never heard such a new word as the Hanjiang Plain, it does not hinder the understanding of the meaning of the word.

"I have been an official for many years, and today I look at this table case and listen to the general's explanation, and I know where the Yangtze River is going to rush!"

"Yes, it turns out that the general of Beifu is not ignorant of military affairs, and he who does not know military affairs is actually an old man!"

……

Sima Yi gritted his teeth and looked at it, but he didn't say anything, obviously he could do this kind of discussion.

Xiahou Nan looked surprised and looked at the sand table in disbelief.

"Gentlemen, looking at this sand table, you can know that if you choose a place to cross the river, the next strategy is to go south from Xuzhou, or go east from Hefei. This road seems to be choking the throat, but these two places come out, it is the lower reaches of the Yangtze River, the river surface is changeable, and Jingkou and Wuxian are the foundation of Sun Quan, so they cannot win quickly. ”

The battle of Weishui is the road taken, and the fertilizer of Weishui and the fertilizer of Hefei are the same fertilizer. Qianqin lost, which confirmed that this was the next policy.

"The central strategy is to take Xiangyang, take the Han River, enter Jiangxia, and cut the Yangtze River defense line into two sections."

Kublai Khan's capture of the Southern Song Dynasty was to die in Xiangyang, and finally succeeded, this strategy can be successful, but it is very difficult, because Xiangyang is easy to defend and difficult to attack, and the Mongolian golden family that once hit the Danube River also had to spend forty years on the Western Front. General Meng Heng is eternal, and Guo Jing is heroic.

"The upper strategy is to seize Hanzhong, enter Tianfu, occupy Yizhou, and go down the river from the upstream."

Jin to destroy Wu and Sui to destroy Chen are all on this path, and the process is very simple, so this is the best policy.

After some discussion, the Yangtze River on the sand table seemed to come to life, rolling the Yangtze River east of the water, and the ministers seemed to hear the river surging and rushing into the sea.

Everyone was silent, and there was only Cao Wu's voice in the hall.

Xiahou Nanyou did not give up and asked: "Now that our army has newly taken Jingzhou, how can we give up easily?" ”

Cao Wu replied: "Strategy is never a desperate bet, since Jingzhou cut the Yangtze River into two sections, our army should take advantage of Zhang Lu, enter Hanzhong, cooperate with Jingzhou, set off on two roads, go down to Yizhou, and capture Liu Zhang." After a few years, after waiting for Yizhou and Jingzhou to be completely annexed, they sent troops and horsemen to divide the road, and went down the river from Yizhou to seize the south of the Yangtze River. ”

This strategy overshadowed Sima Yidu's admiration, and the officials were completely convinced.

Mao Jie sighed gloomily: "When I first started, I thought you were arrogant and arrogant, and you didn't know how to learn, but now I know that I, an old bone, look down on the heroes of the world." Today's matter is that I am ashamed of Gong Cao, General Beifu, farewell! ”

After that, he took his cane and slowly walked out of the hall.

Sima Yi chuckled in his heart and looked at the door.

The officials also looked at each other, not knowing what to do.

"It's just a general to advise, don't be arrogant, don't be extravagant, as an official, you must know the suffering of the people."

Mao Jue's voice came from afar, Cao Wu smiled noncommittally, and continued his deduction: "At that time, the prime minister's ship will go down to Yizhou, and the king of Jinling will be gloomy. Gentlemen, how can you think about the truth of the middle strategy and the next policy without using the best policy? ”

Inside the curtain, Cao Cao slapped his thigh and sighed: "What a Jinling king." Good, good! My Cao family has a small nothing, the world can be determined! ”
