Chapter 829: Geographical Destiny? The Unknown Vulnerability of a Superpower
[From a geographical perspective, when studying the defense capabilities of countries around the world, the importance of natural barriers is self-evident. ]

[The defensive effect of cliffs is far better than that of plains. Many countries have been able to survive for a long time because of their unique geographical conditions.]

[In today's world, if we only consider national strength, Dragon Country, Eagle Sauce Country and Bear Country are undoubtedly the most difficult countries to invade. ]

[These three countries have a huge number of nuclear weapons and a million-level army. If they join forces, they can easily defeat other countries. ]

[But from a geographical perspective, all three powers have obvious weaknesses. ]

[Among them, the geographical defects of the Bear Country are the most prominent. ]

[Although the European part is vast, the terrain is too flat, allowing the enemy's mechanized forces to advance quickly.]

[More importantly, the economy and population of the Bear Country are mainly concentrated in the European region west of the Ural Mountains, while the industrial base in Siberia is weak and it is difficult to provide sufficient backup forces.]

[This has led to the fact that the Russian Bear Country must rely on external assistance in defensive wars. For example, during the Napoleonic Wars and World War II, it was able to counterattack with assistance, but it would be difficult to resist without assistance.]

[The situation in the United States is similar to that in the United States, and they also face the problem of flat terrain. 】

[Although there are natural barriers such as the Rocky Mountains and the Appalachian Mountains, the 9000-kilometer border with Maple Leaf Country and the 3170-kilometer border with Cactus Country are mostly plains.]

[The enemy can choose to attack from the Great Lakes region or along the Grande River without having to attack the mountains.]

[If the United States' power declines in the future and it is unable to continue suppressing its neighbors, historical events similar to the "White House burning" may happen again.]

[This reminds us that national strength and geographical conditions are changing dynamically, and we cannot rely too much on temporary advantages.]

Barrage:

——"Fuck, it turns out that the Bear Country is so weak. I always thought it was very strong."

——"The geography teacher was ecstatic because he could finally use his geography knowledge"

——"So a flat land is not really a good idea. Look at the mountains in our Dragon Country."

——"No wonder the Russian Bear Country is so obsessed with attacking Ukraine. It turns out that it wants to have more buffer zones."

——"The plains are not very good, but once winter comes, no one can advance (break the defense)"

……

The Ming plane.

Zhu Yuanzhang, the founding emperor of the Ming Dynasty, gazed at the sky and read the analysis of geographical defense on it, and couldn't help falling into deep thought.

"Liu Bowen, look at what is said in the sky, the terrain is so important. When I conquered the world, there was a dense network of rivers in the south of the Yangtze River, the Great Wall in the north, the desert in the west, and the sea in the east. Isn't it consistent with this?"

"Your Majesty, you are wise. Our Great Ming is surrounded by mountains on three sides and faces the sea on one side. It is indeed blessed by nature. However, the grasslands in the north are vast. Although there is the Great Wall, we still need to be more vigilant."

Liu Bowen stroked his beard as he analyzed.

"This reminds me. The Yuan people relied on the flatness of the desert to roam freely. When I conquer the world, I will make the northern defense line as solid as a rock. Let the barbarians be terrified!"

Zhu Yuanzhang's gaze became more determined.

"Your Majesty is right. But as Tianmu said, it is not enough for a country to have only natural defenses. It also needs to develop its borders and strengthen its military."

"That's right. I have ordered people to build more cities on the border and to cultivate land and garrison the border. But the north is too empty and it is indeed worrying."

Zhu Yuanzhang stood up and paced in the hall.

"In your opinion, how should we plan this?"

"Your Majesty, I think we can set up more military settlements at important passes, which can both support the troops and increase production. We should also set up more vassal states outside the passes, so that we can use the barbarians to control the barbarians."

"Good! I will send more capable officials to the border to speed up construction. We must not let the enemy take advantage of the opportunity. This natural barrier needs manpower to defend, and it cannot be defended by mountains and rivers alone."

……

In the teahouse, there was a constant stream of conversation.

"This is a new theory. It turns out that the terrain can affect the fate of a country in this way."

"You said that the Eagle Sauce Country and the Bear Country on the sky are the foreign countries in the Western Regions?" "In my opinion, this analysis makes sense. Back then, the Xiongnu was so powerful because the desert was flat, so they could roam freely."

The ancients sipped tea and talked about it.

This statement is refreshing.

Normally I only know that mountains and rivers can protect the country, but I didn’t know it could be described in such detail.

"Speaking of which, our place has beautiful mountains and rivers, so it must be extremely difficult to attack."

"No, it's troublesome enough just to march and transport food."

The more the ancients talked about it, the more excited they became. All the wars they had heard of in the past were now thought to be related to this terrain.

No wonder our ancestors always said that they would rather have dangerous mountains and rivers than wide plains.

"These foreign nations are quite pitiful. Living on the plains, they have to be on guard against all directions at all times."

"Don't be too quick to sympathize. Look, they are living a comfortable life."

“I don’t know what the world will look like in a few hundred years.”

Amid the lively discussions, bursts of laughter were heard from time to time.

Although the content on the curtain discussed military and national affairs, it made everyone watch with great interest.

After all, who doesn’t like to hear these new and interesting insights?

……

Eastern Han Dynasty plane.

Cao Cao looked at the sky for a long time with a serious look.

"I never thought that the importance of terrain could have an impact thousands of years later. Xun Yu, do you have any opinion? Is there anything we can learn from what Tianmu said?"

"Mingsir, what the sky curtain said is indeed meaningful. Now our army occupies Yanzhou, with the natural barrier of the Yangtze River in the south and the plain of Qi in the north. If we want to unify the world, this terrain is indeed a problem."

"Especially the Jiangdong area, which is densely covered with waterways, has always been a battleground for military strategists."

Xun Yu pondered.

"If he wants to go south, the Yangtze River is indeed difficult to cross. Sun Quan uses this to establish his own territory, and I'm afraid it will be difficult to deal with him."

"This sky curtain has reminded me that it is indeed difficult to defend the plains. If Yuan Shao had not underestimated the enemy and advanced rashly in the Battle of Guandu, the consequences would have been unpredictable."

Cao Cao recalled the scene of the decisive battle with Yuan Shao.

Guo Jia interjected: "In my opinion, instead of worrying about the terrain, it is better to plan for the navy first."

"If you want to conquer Jingchu and Jiangdong, the navy is the key. Isn't the maritime advantage mentioned on the sky curtain consistent with this?"

"Besides, the Jiangdong boys are good at naval warfare. If we don't make arrangements early, it will be even more difficult to deal with them in the future."

"Feng Xiao is right. I see that those powerful countries also value both land and sea. If I only care about the north and neglect the navy, wouldn't that be similar to the shortcomings that Tian Mu mentioned?"

"Your Excellency is wise. Although we have occupied the Yellow River basin, the Yellow River bursts its banks and floods every year, which has become a hidden danger."

"Why not take this opportunity to build more water forts and train the navy. Besides, if you want to truly control the Central Plains, the navy is also indispensable."

"Good. This sky curtain reminds me that I can't just focus on the present. As Zijian said, 'Your youthful robe is always in my heart', I should also make more plans for future generations."

"Pass the order down, gather the naval commanders tomorrow to discuss the strategy of training the troops. Although Liu Bei and Sun Quan are a threat at the moment, if we can stabilize the navy, we will be able to defeat them in time."

"You are right. The general trend of the world is closely related to the geographical situation. I just don't know what the world will look like a thousand years from now."

Guo Jia looked at the sky, thoughtful.

"The general trend of the world is that after a long period of division, there will be unification, and after a long period of unification, there will be division. With this revelation from the sky, I must prepare for the rainy day and lay a more solid foundation for the State of Wei."
