Gu Biluo raised his eyes with extremely cold eyes, and his tears had already been burned out by anger, transforming into fierce and cold: "Go out, I don't want to see you again!

"Miss Gu, don't be angry, get angry and hurt your body-" The words were left on her lips by her cold eyes, and the smile that came out froze as well, and she said instead: "Don't you have something to say when you come to me, if you don't say it, I'll go back to sleep." With that, he was about to leave.

Gu Biluo subconsciously said: "Wait!"

Hey, this chick is a workaholic, I don't believe that you don't commit occupational diseases, just remind one sentence, and forget the unhappiness just now, Shen Feng turned his head and smiled earnestly: "Boss, what's the matter with me coming tonight?"

"I ordered you to come tonight, it was really entrusted by General Tang, although you have the ability to be a general, but you lack the knowledge of generals, so General Tang ordered me to teach you some marching essentials overnight. Gu Biluo returned to a rigorous mode in a blink of an eye, which shows her strong ability to regulate emotions, generally this kind of woman is a woman with strong rationality, and as time goes by, her temperament will be highlighted and her personality charm will be released.

Khan, it turned out that he was looking for me to study, Shen Feng smiled helplessly: "The essentials of the march should also follow the accumulation of experience, empty rhetoric, and in the future, I will be bound by fixed thinking." ”

"That's right, since General Tang intends to promote you, I might as well take the world as a pattern and preach the general trend of the world to you. Gu Biluo bowed slightly, his expression was serious and serious, and his temperament was like a breeze in the forest, which made people feel like a spring breeze: "The farmer is simple and incompetent, then he will not lose the time of the sky, and the land will not be lost. ”

"In other words, the general trend of the world is composed of the three complementarities of heaven, earth, and man, the cold and heat of the weather affect the forests, and the separation and convergence of the earth form the mountains and rivers—"

This advanced theory shocked Shen Feng and blurted out: "How do you know that mountains and rivers are due to crustal movements?"

"The movement of the earth's crust – that's how it is best to describe it. Gu Biluo thought about this word carefully, then nodded naturally, and said lightly: "This is my conjecture, and I can't confirm it, but according to historical records, there is no shortage of great earthquakes and anger in ancient times, I think this is just a violent turmoil caused by the squeezing of the earth, otherwise the earth would not suddenly shake violently, what do you think?"

Shen Feng couldn't help but applaud and said, "That's right, what you said is absolutely correct, I really admire you!"

Gu Biluo frowned and said, "Why are you so sure of what I said?" This remark, this is not the first time she has said it to people, but every time she is laughed off, even more ridiculous, she didn't expect that the first person who agreed with her was the person she hated the most.

"Uh-this-" Shen Feng said sharply in his mind: "This is also my conjecture, if you think about it carefully, the shape of the mountain is generally sharp at the top and wide at the bottom, in the shape of a triangle, which is obviously formed by the two plots squeezing to the middle, as for the formation of the river, it is also formed by the formation of the mountain range, the two plots will be separated when the two plots are squeezed opposite each other, and the separation of the plots will form a river." ”

Gu Biluo's beautiful eyes lit up, and her expression couldn't hold back her excitement: "I was just guessing, and I wasn't very sure, but after you said it, I became even more convinced that this statement can indeed be confirmed from the shape of the mountain, but I'm afraid it's hard for people to imagine." ”

Shen Feng nodded and said, "The formation of mountains and rivers is a time that is unimaginable, and it is also the most blank and permanent time in the world. ”

It's a pity that such a person with the same opinion as me is such a shameless person, I can't talk with him all night and talk about the wonderful things in the world, Gu Biluo opened his mouth, wanted to speak and stopped, then sighed lightly, and said lightly: "I still want to tell you about the trend of the world, for thousands of years, after thousands of battles, fighting for a territory, why foreign races are eyeing me Dahua, it is nothing more than because the Central Plains is a rich and vast land." ”

The reason why Dahua is prosperous and rich is because of the crisscrossing of countless mountains and rivers, and it is also for this reason that the military situation in Dahua is extremely complex, and it is a game of Go, and the mountains and rivers are the chess line. ”

The two sat opposite each other by candlelight, Shen Feng listened carefully, for the military terrain, he and Gu Biluo compared, like a Nobel Prize winner and a primary school student, Gu Biluo glanced at him, saw that he looked serious, unconsciously slowed down the speed of speech, and continued: "In the Eastern Han Dynasty, Huan Tan's "New Treatise" said: There is a game of Go in the world, or it is the art of war. and for the above, far away from its sparseness, placed in the encirclement, so that there are many, the victory of the way; the middle, the need to cover the essentials, to fight for profit, so the victory or defeat is doubtful, must be counted; the lower, then guard the corner, tend to be a rebellion, in order to live in a small land, but it will not be as good. ”

From this it can be seen that the geographical pattern of Dahua is a chessboard-type pattern, and then from the perspective of military geography, its geographical pattern is like an irregular Go board, on this non-standard Go board, Guanzhong, Hebei, southeast and Shu are its four corners, Shanxi, Shandong, Hubei and Hanzhong are its four sides, and the Central Plains is its central hinterland. ”

Shen Feng nodded when he heard this, it is indeed divided according to the distribution of mountains and rivers, this is indeed like a game of Go, and it is much clearer to understand it according to the situation of the chessboard.

Gu Biluo said: "Throughout the ages, although this territory is vast, it is mainly the above-mentioned nine regions that have played a decisive role in the wars of the past dynasties, and their importance is often related to the unification and division of the world, the rise and fall of a dynasty, or the survival or death of the Central Plains regime in the war between the Central Plains regime and the nomads outside the Saiwai. ”

The candle flame crackled slightly, and she broke half of the lamp twist with her fingernails, and continued: "In the game of the world, often the land of mountains and rivers is the place where soldiers must fight, and in those places where there are both mountain dangers and rivers and waterways that can be relied on, it is easy to form strategic places. ”

Shen Feng thought of Xiangyang and said: "Xiangyang is the place where soldiers must fight, if the Rouran clan wants to invade the Central Plains in the south, will they have to attack Xiangyang City first?"

Gu Biluo said with a solemn face: "Yes! I assert that if the Manichaean Sect dares to openly raise the name of the previous dynasty to make a rebellion, it must be secretly supported by the Rouran Clan, so this time not only to exterminate the Manichaeism, but also to block the ambition of the Rouran Clan, this time it is necessary to recapture Yiling and Xiangyang!" Although she is a woman, when she talks about the safety of the world, she has a heavy feeling, and first ties the safety of the world to herself.

She really has two brushes, and she points out the key points in one sentence, it seems that Manichaeism is just a pawn of the Rouran clan, because the Rouran clan is still blocked on the grassland, Sister Shu said that there is a Rouran army to assist Manichaeism, which is probably sent secretly over the years, it can be seen that the leader of the Rouran clan has been laying out for a long time.

Gu Biluo temporarily swept away his worries and continued: "Just talking about the region, let's talk about the mountains and rivers at this time, several columns of mountains and rivers in the east-west direction and several columns of mountains and rivers in the north-south direction crisscross and divide the hinterland of Dahua into several relatively independent areas. You can see it as a three-layered nine-grid map, roughly northeast to southwest, among them, a series of mountains in the eastern edge of the second layer - from Yanshan in the north, along the Taihang Mountain in the south, through the Songshan Mountains, Tongbai Mountain, Dahong Mountain, and then turn to the western Hubei and Xiangxi mountains and connect with the southwest Yi people's residence, which is an important dividing line between the east and the west. There are also several levels between the north and the south, and the main dividing lines are the Yangtze River, the Yellow River, the Huai River, and the Qinba Mountains—"

Gu Biluo talked about the distribution of the entire mountain range and river in detail, if she didn't have a general understanding of geography, no matter how detailed she spoke, it would be difficult to understand, Shen Feng understood a little with difficulty, and asked: "Do you have a map here, it will be more vivid on the map." ”

Gu Biluo bowed slightly: "It is indeed better to talk about the effect according to the picture, but at this time I have no paper or pen on me." ”

Shen Feng smiled and said, "It's not simple, you go outside with me." The two came outside with candles, and Shen Feng picked up a branch and a pile of stones and said, "You use a branch to draw a picture on the ground, and then push up the mound of soil as a mountain range, and then mark the location with stones, so that I will be much clearer." ”

"It's okay!" Gu Biluo nodded, and then bulldozed the ground and drew as he said, and the two discussed while drawing.

"The strategic significance of mountains and rivers is different, the mountain range is important to block, and the most important is that there are channels to pass, the significance of the river is important to circulate, and the most important is to have a stronghold to hold, generally speaking, the fault zone of the mountain or the valley lowland formed by the headwaters of the river through the mountains is convenient for the traffic channel through the mountains. For example, the Guanzhong Sisai, Taihang Bacheng and several plank roads through the Qinba Mountains are like this, and the rivers are mainly used as channels for manpower and material transportation. With rivers as a barrier, it is also necessary to establish strongholds at important crossings or at the confluence of tributaries and main streams to ensure control of these rivers. For example, Mengjin and Pujin in the Yellow River, Guazhoudu and Quarshidu in the Yangtze River, Yingkou, Vortex and Sikou in the Huai River, all of them were formed with the formation of important military bases. ”

Gu Biluo stood on the ground, waving a branch in her hand, and the power of the world came out of her mouth, which shows her extensive knowledge: "If there are mountains and dangers to rely on, it is easy to establish a base in a chaotic situation, form a local order, and accumulate strength; if there are rivers and waterways that can circulate, it is convenient to project forces to the outside, to expand outward, and to intervene in the overall situation. ”

After that, Gu Biluo suddenly asked: "I explain to you in detail, on any of your Dahua territory, there are some passes that have always been fought for by soldiers, so let me ask you, if Xiangyang cannot be captured, where will you defend it?" This seems to be a question in her class, she is like a teacher, she will ask students questions, in order to see if Shen Feng understands.

If you want to test me, don't you know if I'm a scholar, just get a little bit, the first place in a study, Shen Feng smiled non-newest at her actions, and then replied: "Xinyang Jigong Mountain, that is, Wushengguan." ”

Wushengguan is known as a piece of feng shui treasure land of "Qingfen Yuchu, air pressure Songheng, and three rivers", which is the junction of the east and west of the Tongbai Mountains and the Dabie Mountains in the eastern section of the Qinling Fold Mountain System, and is the middle point of the north and south geography, the watershed of the north and the south, for thousands of years, Wushengguan is the place where the soldiers of the Central Plains in the north and the Jianghan in the south must fight.

Gu Biluo bowed slightly, and said lightly: "Very good, I'll be here today, and we'll talk about it tomorrow night." So he went back to his tent.

Shen Feng was also exhausted, and when he returned to the tent, he immediately fell asleep and did not say anything all night.
