Chapter 246
A vigorous team entered the Qinling Mountains and headed for the northwest border of the Tang Dynasty.

Ni Tu, who was guarding inside the car, was drawing a map of the Tang Dynasty on a large silk scroll.

The Western Turks were still disturbing the western part of the Tang Dynasty. It was not until Su Dingfang went to war a few years later that he finally forced Shaboluo to go to Shiguo.After he was captured, the Western Turks died.

Later, it will be divided into Kunling and Mengchi two capital guards.

Later, he moved to Anxi Dufu in Kucha.

On the southwestern border, the Qinghai-Tibet Plateau was temporarily occupied by the Tubo people, who kept that territory for the Tang Dynasty.

In the Cheng Mansion, Ni Tu specifically checked the military reports on Tubo, and the actual situation was not much different from the historical materials collected by later generations.

Tubo rose during the period of its Zanpu Songtsan Gampo, moved its capital from Pibocheng in the south of Shannan to Luoxie, annexed the same tribe of Supiyang, broke up Dangxiang and Bailan, defeated Tuyuhun, obtained its old land, and conquered the Kashmir region to the west. Big and small Bolu, went south and took Nibera and other places, not only unified the Qinghai-Tibet and Kham-Tibet Plateaus, but almost included Nepal and Kashmir and other places in their territory.

Ni Tu knew that when civil strife broke out successively in the later generations of the Tang Dynasty, such as the Anshi Rebellion, Zhu Shi Rebellion, and Fanzhen Disaster, Tubo would take the opportunity to expand eastward and northward, encroaching on Longyou and Hexi, and occupying Beiting and Anxi.Once the territory reached its peak, it would form a land bordering on the Congling Mountains in the west, the Arab Empire in the southwest, Tianzhu in the south, the Pamirs and the Indus Valley in the east, and the Atlantic Ocean in the west.

As Ni Tu drew the map, he couldn't restrain his emotion.

The territory of the Tang Dynasty under his pen stretches from the Korean Peninsula in the east to Hengshan, Vietnam in the south, the Aral Sea in the west, and Lake Baikal in the north, covering an area of ​​about 170,000 square kilometers.An overwhelming sense of pride arises spontaneously.

Such a territorial map laid a solid foundation for the later Yuan Dynasty, which stretched from the Sea of ​​Japan in the east, to the South China Sea in the south, to the Tianshan Mountains in the west, and to the Arctic Ocean in the north.

If such a prosperous spirit has not weakened, if this kind of territory has been continued to future generations, how proud the people of future generations will be.

At this moment, the curtain of the sedan chair was raised, Ni Tu raised his head and saw that Cheng Zheng had come in again to be lazy.

"what is this?"

As soon as Cheng Zheng entered, he saw a large map spread out.

Ni Tu put down the writing brush stained with red ink, pointed to the map of the territory of Tang Dynasty, and explained to Cheng Zheng one by one.

"This... is this the territory of our Great Tang?" Cheng Zheng stared wide-eyed, looking at every place in surprise, for fear that it would be a pity to miss any part.

"It's amazing!" Cheng Zheng stretched out his thumb and exclaimed: "The whole picture of Tang Dynasty hesitates a person, and this Chang'an is like a person's heart. Look at this picture, Chang'an is just at the core of Datang The location is like the heart of the Great Tang territory. No wonder the Emperor Gaozu chose Chang'an as his capital instead of Luoyang, so he already had such a map of the Great Tang territory in his heart!"

"Look, from Chang'an to the east you can reach the sea, to the south you can reach the rich and vast Lingnan, and to the west you can go all out along the Hexi Corridor. What's more, Chang'an guards the main roads of the Qinling Mountains and the Loess Plateau. One man guards the gate and ten thousand men cannot open it, attacking can attack foreign enemies, defending can prevent foreign enemies from invading, even if retreating, you can retreat to Luoyang, and even go east or south."

Ni Tu didn't expect Cheng Zheng to have some military knowledge after all.

He nodded and asked: "This opinion is very good, but I want to ask my brother a question, how does Luoyang compare to Chang'an?"

"Luoyang, this old man taught me." When Cheng Zheng heard that he knew something, he was immediately happy, and he began to show off with a big grin.

"A Weng said that in terms of geographical advantages, Luoyang is not inferior to Chang'an. Back then, Marquis Zhang Liang praised Luoyang's geographical advantages. From the perspective of defense alone, Luoyang actually has more advantages than Chang'an. Luoyang itself is a basin, Surrounded by high mountains like Zhongtiao Mountain and Xiao Mountain, the Luoshui River and the Yellow River can serve as barriers in front, and the Mang Mountain next to it can also be used as a support.”

"But Luoyang has a disadvantage, that is, it is in a basin. The basin is high around, and the terrain gets lower as you go in. Once you are surrounded by people, you can only wait for dumplings to be made. At that time, food and grass Once it is cut off, and the water source is cut off again, it will be difficult to persist for a long time. Luoyang is not a big place, and the population and towns all occupy flat land. These places should be the place to grow food. But as the population grows, they can only occupy cultivated land. In the long run, although the grain fields are fertile, they cannot support so many people and livestock. Once they are outflanked, the fallen leaves will not be enough for long-term consumption. Although Emperor Sui Yang built the Grand Canal , specially used to transport grain. But if the Grand Canal is cut off, Luoyang may fall into a dead end.”

"Okay! Based on this, brother, I can comment on the advantages of Chang'an, and why Gaozu chose to make his capital in Chang'an."

"Well, Ah Weng didn't tell me. He just said that Chang'an City is very strong. I don't know anything else." Cheng Zheng scratched his head.

Ni Tu smiled and pointed to the map and said, "Look, brother, Chang'an has been a battleground for military strategists since ancient times, and whoever occupies this place will be helpless for others. People who can fight well, when they reach the outside of Chang'an city, they will be helpless, and they will be turned away from the door and not allowed to enter. During the period of Emperor Jing of the Han Dynasty, the princes and kings rebelled, and such a thing happened again, but they were still bound outside the city of Chang'an .”

"Ah, why is that?" Cheng Zheng found it more interesting the more he listened, and he couldn't help asking.

Looking at this vivid map, Cheng Zheng listened more carefully.

"Chang'an City is composed of four passes, Tongguan, Wuguan, Dashanguan and Xiaoguan, each of which is a dangerous pass, and can be called the first pass in the world. The valley is connected, and the Yellow River is used as a barrier. In addition, the deliberately built city is only wide enough for a car to pass through. As long as the city gate is guarded, not even a bird or a fly can fly through it. Anyone with Chang'an ideas will have to scratch their heads once they face Tongguan."

Cheng Zheng looked at the four clearly marked city gates and nodded approvingly.

"Let's talk about the terrain, let's talk about the food, grass, water and other materials involved in the war." Ni Tu continued: "The battle is actually about logistics supplies. The Guanzhong area where Chang'an City is located is a natural granary. The land in Guanzhong is fertile and open. , high food production. And with a large population, there is no need to worry about the supply of troops.”

"Relying on its various advantages, it is necessary to analyze specific issues in detail, taking into account the people's support at that time, and the financial and material resources at that time. At the beginning of Gaozu's founding of the country, the population and property decreased sharply, and the treasury was poor. And because of years of experience War, people's livelihood is dying, people are in dire straits, and all industries are waiting to be flourished. The most urgent thing to do is to restore their livelihoods, settle down in agriculture, commerce and industry, provide food for the people, and provide things for the rich merchants to stabilize the hearts of the people and give them sustenance. Such a situation Under the circumstances, it is impossible to have a large amount of funds to guarantee moving the capital elsewhere. This is one of them."

"Secondly, it's about people's support. Although the palaces in Luoyang are extravagant, Luoyang was built by Emperor Sui Yang. The construction of Luoyang's luxurious palaces and the construction of the Grand Canal were not to attract the people's admiration, which eventually led to the ruin of the Sui Yang Empire. If my Tang Dynasty put the capital in Luoyang at the beginning of the founding of the country, it will inevitably cause criticism. They will think that the emperor of the Tang Dynasty is actually the same as Emperor Yang of the Sui Dynasty, and they are all emperors who are greedy for enjoyment. Will it be the one who wants to leave? The old path of Emperor Sui Yang? The people's support must be clear."

"Brother's analysis makes sense! And this map is even more vivid. Once you read it, you can immediately understand the profound and difficult truths. If Ah Weng had placed such a map of the Tang Dynasty in front of me back then, I'm not stupid! Brother, how do you know this map?"

"This is part of the tutor's curriculum, so it's not worth mentioning!"

"What! Such a secret technique is only part of your schoolwork, why do you look down upon it? In my opinion, this is a top secret related to the fate of the Tang Dynasty. You must hide this map! Don't let others Gotta go."

Ni Tu smiled slightly, and said: "It's because all the strange people in the world have thoughts like yours that my Huaxia's wisdom has been cut off. Of course, I have to learn to share good things. Come on, call me all the people above the team deputy!" come over."

"What! You want them to see this treasure map?"

"Not only do I have to let them look at the map, but I also teach them how to make maps and draw terrain, and I also teach them how to make sand tables."

"What? Absolutely not!" Cheng Zheng jumped up excitedly, so high.
