In the last years of the Warring States, Li Mu, a general of the State of Zhao, went south and continuously drew troops from the Great Wall in the north. When the State of Zhao killed Li Mu due to dissension, Handan fell, and the State of Qin destroyed Zhao, the entire Northwest Great Wall was useless.
Since Li Mu broke the Xiongnu, beheading more than 100,000 people. The Xiongnu did not dare to cross the yin mountain line, and the Xiongnu children heard Li Mu's name and did not dare to cry at night. Li Mu died, Zhao Guo died. The Huns swept away the clouds and the haze, and everyone sharpened their knives and guns and were eager to try.
Touman Shan summoned the tribal chiefs to the Dragon City to worship ancestors, heaven and earth, and ghosts and gods. The chiefs all said that they were willing to go south to shame before the snow. After more than twenty years of rest, the Xiongnu soldiers were strong and strong, and their strength was especially stronger than that year.
Tou Man Shan Yu led his army across the YinShan Great Wall, galloping across the river without any zhao army stopping him. The Xiongnu occupied the fertile grassland above the "several" characters of the Yellow River, and also crossed the Yellow River to occupy Henan.
After Qin Shi Huang unified China, with Meng Tian as the main general, Wang Li as the deputy general (to compensate Wang Qi's father and son), the eldest son Fu Su as the overseer, and involved in various generals, commanded 300,000 troops, and invaded the Xiongnu in the north.
Under the clouds, in the camp alone, a short series of alarm horns were heard.
In front of a small hill, there were many people. I saw a dead man lying on the middle side, a centurion of the Xiongnu. A cluster of arrows passed through the wooden armor on the chest and penetrated through the chest, and the arrow actually drilled out from the back. Tou Man Shan Yu and the other leaders were stunned, the Qin army's powerful arrows were much stronger than Zhao Guo's.
The Qin army's crossbow mainly used two kinds of arrows: the short collar small copper dart is a light arrow for long-range shooting, and the long collar large copper dart is a heavy arrow used to break armor at close range. The long collar is designed to penetrate the bronze armor, not to mention the wooden armor.
Two rows of copper hammers were placed on the ground, and the leaders studied them. I saw that all the arrows were three-edged hammers, the three arcs were almost identical, and the most frightening thing was that each copper hammer was almost exactly the same. Hun arrows are made by the warriors themselves, and everyone is different. Previously, Zhao Guo had also carried out mass production, but each blacksmith had a different level of craftsmanship, and the difference in arrows was still obvious.
With a solemn face, Touman waved to the leaders, "Prepare to retreat." ”
In that year, the Qin army recovered Henan Province, set up forty-four counties, and moved inland prisoners to live. The following year, Meng Tian led his troops north across the Yellow River and took all the territory south of the Yin Mountains.
The First Emperor ordered Fu Su, Meng Tian and Wang Li to connect the Great Wall built by the three kingdoms of Yan, Zhao, and Qin, connecting end to end. From Lintao in the west to Liaodong in the east, it is called the Great Wall. Winters in the Northland are cold, snowy, and windy, often freezing fingers, cracking skin, and freezing to death.
The Xiongnu sphere of influence retreated to the north of the Great Wall of Yinshan, and under the military power of Donghu and Yue, it once shrank to the north of the desert.
In 115 BC, the Qin Dynasty opened the northern Chi Road from Xianyang to Jiuyuan, excavating mountains and valleys along the way. The road is fifty paces wide, and every three inches, a green pine plant is planted. The road is wide and flat, and the carriages and horses walk like flying. Two rows of pine trees, verdant into shade, pavilions like a cover. The breeze passes everywhere, the sound of the waves, the scenery is excellent.
In early May, the weather was cool, and the Qin army had more than 200,000 soldiers, more than 500,000 civilians, more than 100,000 warhorses, and tens of thousands of vehicles.
All the way to the grain and grass, thousands of miles. On the road, the dragon flag covers the sun, the phoenix covers the sky, the car is like water, and the royal horse is like a jiao. The mighty battle of the First Emperor, although the Yellow Emperor, Shang Tang, and King Wu of Zhou were incomparable.
Daytime cars come from Xuanhe, golden drums, Khotanese, county-contributed food treasures, piles of mountains and seas. At night, the lights are hundreds of miles away, and when you look up, it looks like a star in the sky.
Guanzhong, also known as Qinzhong, the Qin Dynasty combined the new land of Mengtian with the old land in the northwest of the Zhao Kingdom, called the new Qinzhong, which was later known as the Hetao region, and also built a Xianyang City in Yunzhong County. The Qin Dynasty's planning of the Hetao region (New QinZhong) was roughly an area with a population of thousands of miles and a single defense against the Xiongnu.
【Loop Area】
The Hetao area, roughly the upper part of the "several" characters of the Yellow River, is the wilderness of the river curve and abundance.
In ancient times, the Yellow River flooded, and the folk had the saying that "the Yellow River is harmful, only rich". Although the Hetao area does not have much precipitation, it has flat terrain, fertile soil and conditions for large-scale farming.
The Hetao area roughly includes the East Tao Plain (the former and the back set plain), the West Tao Plain, and the Henan Land.
【Front set plain】
The Qiantao Plain, also known as the Hehaote Plain, was called the Shule River and the Tumo River in ancient times, which is roughly the area of Daqingshan, The Barbarian Han Mountain and the Yellow River Siege. The Qiantao Plain stretches from the east Ubulagou mouth on the outskirts of Baotou City in the west, to the Barbarian Mountains in the east, to the Daqing Mountains in the north, and to the Yellow River and the Lingle Loess Hills in the south. The Qiantao Plain is about 1,000 meters above sea level, is a fault basin, about 180 kilometers long from east to west, 19 kilometers to 150 kilometers wide from north to south, and an area of about 10,000 square kilometers.
【Back Set Plain】
The Houtao Plain is roughly an area surrounded by the Wolf Mountain, the Yinshan Mountains, the Ula Mountains and the Yellow River. The Houtao Plain stretches from the mouth of Bayannaoer City [dèng] in the west, to the qianqi of Wulat in the east, to the Wolf Mountain in the north, and to the Yellow River in the south. The Houtao Plain is about 1000-1100 meters above sea level, about 180 kilometers long from east to west, 40-80 kilometers wide from north to south, and covers an area of about 10,000 square kilometers.
【Xitao Plain】
The Xitao Plain, also known as the Ningxia Plain, is roughly an area enclosed by the Helan Mountains and the Yellow River, from Zhongwei Shapotou in the south to Shizui Mountain in the north. The Xitao Plain, at an altitude of 1100-1200 meters, is formed by the alluvial accumulation of the Yellow River and its forks after the fault and subsidence. It is about 280 km long from north to south, 10-50 km wide from east to west, and has an area of about 7,800 square kilometers.
【Henan】
Henan is roughly the area where the Yellow River "several" characters are surrounded by Baiyu Mountain and Loess Hills, including the Kubuqi Desert, the Ordos Plateau, and the Maowusu Sandy Land from north to south.
