Video spoilers history, starting with the blitzkrieg on Poland

A new sky appeared.

The picture shows the Guanzhong Plain taken from an aerial drone.

Follow the lens.

The view from the high altitude slowly extends from the steep Hangu Pass into the 800-li Qinchuan plain with thousands of miles of fertile fields.

And the background music gradually started.

The sky begins to tell the story.

[This is the most magical place for making a king in Chinese history - Guanzhong Plain! ]

[In the long course of history, many powerful regimes rose in the Guanzhong region. ]

【King Wu started from here to overthrow the Shang Dynasty.】

【Qin Shi Huang forged the first centralized empire here. 】

【The cavalry of Emperor Wu of the Han Dynasty set out on the Silk Road from this point.】

【Emperor Taizong of Tang created a prosperous era where all nations came to pay tribute.】

【These regimes left an indelible mark on Chinese history. 】

[One of the key factors for their brilliant achievements is the unique geographical conditions of the Guanzhong region.]

【Why is this piece of land less than 60,000 square kilometers? 】

[Can it become the ultimate strategic fortress in the era of cold weapons? 】

[Next, let us analyze the geographical advantages of the Guanzhong region in detail and explore the secrets of the prosperity of these regimes. ]

【First, let’s look at the topography. 】

[Guanzhong is located in the central part of present-day Shaanxi Province and is surrounded by mountains, forming a natural defense barrier. ]

[The Xiao Mountains in the east, the Long Mountains in the west, the Qinling Mountains in the south, and the Loess Plateau in the north tightly surround Guanzhong. ]

[In the ancient military defense system, mountains are an extremely important defense element. ]

[If the enemy wanted to invade Guanzhong, they had to cross these mountains first, which undoubtedly brought great obstacles to the march. ]

[After the soldiers traveled a long distance and crossed mountains and ridges, their physical strength was greatly depleted, and their combat effectiveness would also decrease. ]

[Supply is even more critical! ]

[Moreover, the ancients built many passes in the dangerous places of these mountains. ]

[The most famous of these are the "Four Passes of Guanzhong", namely Hangu Pass in the east, Dasan Pass in the west, Wu Pass in the south and Xiao Pass in the north.]

[These passes are like solid keys, firmly controlling the entrances and exits of Guanzhong. ]

[As long as we hold on to these four passes, the Guanzhong region will be safe. ]

[When An Lushan rebelled, if Emperor Xuanzong of Tang had not forced Geshu Han to leave Tongguan and give up his life, the rebels would not have been able to enter Guanzhong at all. ]

[The Qinling Mountains in the south are like a natural wall 500 miles high. Once the Wuguan Pass is locked, the country is invincible! ]

[To the west, Dasan Pass blocks the Longshan Gorge. ]

[Zhuge Liang was defeated here every time he went to Qishan six times. 】

[Xiaoguan in the north guards the Loess Plateau. ]

[Take the Qin Dynasty as an example. The Qin State successfully resisted the attacks of the six states in Shandong many times with the help of Hangu Pass. 】

[Hangu Pass is located in the Xiao Mountain. It has a dangerous terrain and narrow roads. It has the reputation of "one man guarding the pass, ten thousand men cannot open it." ]

【Look at this terrain! 】

[In the east, the Yellow River makes a right-angle bend, and Hangu Pass is stuck in the crack of Mount Xiao. ]

[At that time, the coalition army of the six countries had a million soldiers squeezed into a narrow mountain road, and was blocked by the 20,000 Qin soldiers, and was in a dilemma - this is what Jia Yi wrote in "On the Qin Dynasty": "Millions of people fled north and were ruined"! ]

[The coalition forces of the six nations launched attacks on Qin several times, but were basically blocked outside Hangu Pass.]

[Even if the enemy occasionally breaks through Hangu Pass, Qin still has other passes as follow-up defense lines. ]

[This unique geographical condition provided a relatively stable external environment for the development of the Qin State during the Warring States Period.]

[It enables them to develop their own strength with peace of mind, gradually rise and eventually unify the six kingdoms. ]

Outside the sky.

Qin Dynasty.

Ying Zheng saw the video and smiled slightly, "Twenty thousand people at Hangu Pass to stop a million-strong coalition army?"

"This is the bravery of the Qin soldiers, not the terrain."

"But Guanzhong is really good."

"The fertile land of Guanzhong has nurtured millions of armored soldiers."

"It is truly the birthplace of our Great Qin!" When saying this, Ying Zheng's heart was filled with pride.

I also feel that the ancestors of the Qin Dynasty really found a good place.

Li Si also followed Ying Zheng's smile and said:
"Guanzhong is surrounded by fortresses on all sides, and Hangu Pass is a pass where one man can block ten thousand. The coalition forces of the six nations invaded many times, but were always repelled by our Great Qin."

"As long as we hold these passes, the Qin Empire will be as stable as Mount Tai."

Ying Zheng nodded and said slowly:
"You must keep in mind the advantages of Guanzhong."

"At the same time, we must also remember that Guanzhong was not given to us by the King of Zhou for nothing."

"It was our ancestors of the Great Qin who came from the west of the world and gradually dominated Guanzhong."

"Stolen from the hands of the barbarians with blood and sand."

"It was developed bit by bit by the Qin people from generation to generation."

"Let future generations remember the foundation of the rise of our Great Qin, and let them understand that protecting Guanzhong is protecting the future of our Great Qin!"

The sky curtain also continues.

【Looking back at the Han Dynasty, Liu Bang was able to win the Chu-Han Contention, and the geographical advantage of Guanzhong played a crucial role. 】

【Liu Bang used Guanzhong as a stable base, made full use of Guanzhong's resources, and continuously expanded his military and economic strength. 】

【Finally, he turned defeat into victory and established the Han Dynasty.】

【From here we can see that the Guanzhong region is rich in natural resources. 】

[The 800-li Qinchuan area has fertile land, and the Wei River runs through it, providing convenient conditions for agricultural irrigation.]

[In ancient society where agriculture was the foundation of the country, fertile land and sufficient water sources were important guarantees for food production.]

[The Guanzhong region had been well developed as early as the Western Zhou Dynasty, and by the Qin and Han Dynasties, it had become an important grain-producing area in the country.]

[The abundant grain production not only met the living needs of the local people, but also provided sufficient supplies for the army. ]

[In addition, the Guanzhong region is rich in mineral resources, and minerals such as copper and iron are important raw materials for manufacturing weapons and agricultural tools.]

[Su Qin said this during the Warring States Period: fertile fields stretch for thousands of miles, with abundant reserves. ]

[Qin Shi Huang was able to build the Great Wall, construct Afang Palace, and fight the Huns at the same time, all thanks to the huge granary in Guanzhong.]

[Sima Qian directly revealed his cards, saying that Guanzhong's wealth accounted for 60% of the world's wealth! ]

【During the Tang Dynasty, agricultural production in the Guanzhong region reached new heights. 】

【The government has vigorously built water conservancy projects, further improving the irrigation conditions of farmland on both sides of the Wei River. 】

[At the same time, the Tang Dynasty established many official handicraft workshops in the Guanzhong region, using local mineral resources to produce a large number of weapons and exquisite handicrafts. ]

[These resources not only laid the material foundation for the prosperity of the Tang Dynasty, but also provided strong support for the military expansion of the Tang Dynasty. ]

Outside the sky.

Tang Dynasty.

Li Shimin saw the sky and said that Guanzhong was rich.

While feeling proud in my heart.

There were also some sighs.

"When the Tang Dynasty established its capital in Chang'an and pacified the world, the Guanzhong region played an indispensable role."

"In the past, due to its strategic location, it was difficult for foreign enemies to invade. In addition, the fertile land and convenient transportation inside made it possible for our Tang Dynasty to achieve its current prosperity. It is truly something to be proud of."

"Do you think Guanzhong is rich?"

"Guanzhong was indeed rich in the past."

"But since the Jin Dynasty, Guanzhong has become worse with each generation."

"The population carrying capacity of Guanzhong is really insufficient now."

"Soil erosion has worsened, and food production is not as good as before."

"It is indeed a great threat to our Tang Dynasty."

"Although I have already ordered the construction of water conservancy projects in the surrounding areas, vigorously promoted afforestation, and restored the ecology of Guanzhong."

“But it’s still not enough.”

"Look, Chang'an is short of food again recently."

"Although I have sent people to transport grain from Guandong."

"But Sanmenxia is a mainstay and it is difficult to transport it by water, so we can only use vehicles to transport it here."

"It's really hard to transport this food." (End of this chapter)
