That breath, as if pinching Cao Ying to death is as insignificant as pinching an ant to death, even if the fourth and third dukes, Yuan Shao, who was based in the four states of Hebei, faced Cao Ying, who was still weak, did not dare to boast of such Haikou.

However, the young man in his early thirties in front of him dared.

Liu Bei and Xu Shu, as well as many Jiangdong generals who were sitting with them, all had a little surprise on their faces. At this moment, Liu Bei must be laughing in his heart at the bravado of this young descendant.

Among all the people, only Liu Feng was in the calmest mood, because only he knew that this Mei Zhoulang in front of him was by no means the kind of person who talked on paper and talked about it, and the reason why he dared to release such unbeatable rhetoric was because he did have extraordinary strength.

"Hehe, Gongjin is really courageous, if you have such confidence, I will be relieved."

Liu Bei first complimented with admiration, then changed his words, twisted a few strands of beard and said: "But Cao Ying, this person is cunning and cunning, according to his heart, he does have a bit of talent for using soldiers, I have been fighting with him for more than ten years, and I know his methods very well." Now he is coerced to surrender Jingxiang, there is an elite northern army on the land, and there is a Jingxiang naval army on the river. So I think, shouldn't we be more conservative? ”

Is Liu Bei tactfully persuading Zhou Yu not to be too aggressive, or staying in Xiakou honestly, and preparing to fight a tough battle to defend Xiakou with the mentality of a weakling.

Zhou Yu smiled: "Xuande Gong has forgotten that one of the reasons why we thought that the two alliances could defeat Cao Ying was that Cao Jun had the weakness of not being accustomed to water warfare. In this case, then why be afraid, it is time to take advantage of our strengths and kill the Cao thief with one blow. ”

Zhou Yu's tone became bigger and bigger, not only did he take the initiative to meet Cao Jun, but he also planned to take Cao Ying's head together.

Cao Ying's weaknesses are nothing more than the initial descent of the Jingzhou Navy Army, the people's hearts are not attached, the elite of the Northern Army is tired from afar, and they are not accustomed to the wet and cold climate of autumn and winter in the south.

However, even if there are all kinds of weaknesses, Cao Ying at this time, no matter how weak he is, he is not as weak as the predicament of the official crossing back then. And the strength of their Sun-Liu coalition army, no matter how strong it is, can it be stronger than the once invincible Yuan Shao?

Liu Bei obviously knew all kinds of benefits and harms, and he really couldn't figure out where the almost conceited self-confidence of Zhou Yu in front of him came from.

Only Liu Feng, who knew it well, couldn't wait to end this senseless argument as soon as possible, and sat back and watched Zhou Yu put on a good show with peace of mind, but he couldn't say anything, so he had to cooperate with Liu Bei, and his expression pretended to be shocked and watched this controversy.

Liu Bei saw that he couldn't convince Zhou Yu, so he secretly squeezed his eyebrows at Xu Shu, suggesting that he hurry up.

The horizontal eyebrows condensed into a unity, at this moment Xu Shu's attention did not seem to be arguing in front of him, those deep eyes were staring at the large map hanging on the bulkhead of the ship, Liu Feng, who was familiar with Xu Shu, could see that he was now falling into some kind of contemplation.

Liu Feng's gaze therefore moved to the map, which was a map about Jingzhou, which was different from what Liu Feng had seen before, on this map, the cities, mountains and rivers were marked in great detail, and even the seemingly insignificant tributaries of the Yangtze River were clearly reflected on the map.

Liu Bei has been in Jingzhou for so many years, but the map in his hand is far less detailed than that of Dongwu, and he has touched the background of other people's families so clearly, it seems that Dongwu is determined to win Jingzhou. ’

While Liu Feng sighed, Xu Shufang reacted from his distraction, and at that moment, some kind of conscious gaze seemed to flash in his eyes.

"Governor Zhou, if I guessed correctly, Governor Zhou said that he was going to take the initiative to go back to the upper reaches of Xiakou to meet Cao Jun, I'm afraid there is still a last resort, right?" Xu Shu did not persuade Zhou Yu, but instead questioned him.

Zhou Yu's handsome face moved slightly, and said with a faint smile: "It seems that Mr. Xu is really not in vain, but I want to hear what Mr. Xu thinks I have to do." ”

Everyone present, including Liu Feng, was also curious.

Xu Shu stood up, walked to the big map, raised his arm, and pointed his index finger at a place on the map: "The reason why the governor is in a hurry to trace the west of the river is that he wants to rush to seize this place before Cao Ying." ”

More than a dozen pairs of eyes moved towards the map in unison, swept along Xu Shu's fingers, and saw two words - Lukou.

"What's so special about the terrain of this land mouth, I have to fight for it?" Zhou Yu obviously admitted Xu Shu's judgment by saying this, but he was still interested in hearing the reasons for his inference.

Looking at the land mouth on the map and listening to the word "terrain" in Zhou Yu's mouth, Liu Feng suddenly remembered a passage in Sun Tzu's Art of War: The man who is the terrain is also the help of the soldier. Expect the enemy to win, calculate the danger far and near, and the way of the general is also. Those who know this and use the war will win, and those who do not know this and the war will lose.

According to the annotation in that mysterious note, this passage is changed to an easy-to-understand statement, that is, the terrain is an auxiliary condition for the use of troops, and it is the duty of a general to correctly determine the enemy's situation, formulate a plan for victory, study the danger of the terrain, and calculate the distance of the road. Those who understand these principles to guide operations are bound to win, and those who do not understand these principles to direct operations are bound to fail.

Topography is crucial to the success or failure of a battle, if not the deciding surname.

Liu Feng's gaze moved to the map again, the word "Lukou" was printed upside down in the brown pupils, and he was thinking repeatedly in his heart, what was so special about that inconspicuous small place, which made Zhou Yu not hesitate to stay away from the support of Dafang, and did not hesitate to stretch the supply line long, and rushed forward for a long time, going back to the west of the Jiangxi to confront Cao Ying.

Suddenly, Liu Feng's attention shifted from Lukou to the thin line drawn in cyan next to him, which represented the river on Zhou Yu's map.

'There is Hanshui in Xiakou, and there is Fanshui in Fankou, so Lukou should be the mouth of Lushui into the river, and this Lushui seems to be a little special. ’

Just as Liu Feng saw the doorway, Xu Shu's frowns on the side of the map were fully furrowed, and he said with a smile: "Lukou is the mouth of the land and water into the river, if the Cao army seizes this place, you can go upstream along the Lushui River, pass through the Mufu Mountain on the south bank, and then take the land route to reach Chaisang, if the cavalry only needs a few kung fu." Even if the Cao army did not take Chaisang, they could attack Xiakou from behind through the Xianpu Corridor from Lukou, and if such a critical place was allowed to be seized by the Cao army, the consequences would be unimaginable. Governor, this is the real reason why you want to seize Lukou. ”

The words made everyone present suddenly realize, and even Zhou Yu was shocked.

However, Zhou Yu's surprise was only for a moment, and then he got up and walked to the map, laughing and saying, "Mr. Xu has finally opened my eyes today." Yes, what Mr. Xu said is that the way of geography in the art of war is deep, but this time, I went back to Jiangxi, and I wanted to grab it from Cao Thief, but it was not Lukou, but here. ”

The fingertips of plain white jade lightly touched on the map, and followed his fingertips, Liu Feng's heart moved slightly.

Where he was pointing, there were two small words written - Chibi.
