The people of the Zhou Dynasty called themselves Huaxia, took the Central Plains as the center of the world, and called the people from all directions around the Central Plains Dongyi, Nanban, Xirong, and Beidi respectively to distinguish Huaxia. Beidi is the general name of the ancient Chinese tribes to the northern non-Chinese tribes. After the middle of the Spring and Autumn Period, Di and Rong were obviously different in terms of region, but throughout the Spring and Autumn Period, and even before the middle of the Warring States Period, Rong Di was still often mixed, and some tribes still had both the titles of Rong and Di. During the pre-Qin period, China referred to the northern nomadic tribes as Beidi, and later the Di people were gradually assimilated by the Hu people who rose up in the Chinese and Mongolian plateaus. The Hu people mainly refer to the Xiongnu, a northern nomadic people during the Qin and Han dynasties. In addition, it also includes some tribes such as Linhu, Loufu, Donghu, Yueshi, and Yiqu that eventually merged into the Xiongnu.

Linhu and Lou Fu are one of the oldest primitive tribes in northern China. During the Warring States period, the seven powers competed for power, and Yan Zhao often annexed its neighbors by force in order to expand the territory. In this regard, Lin Hu and Lou Fu behaved more "weakly". Under the pressure of Zhao Yan, Lin Hu and Lou Fu moved again and again, first from northern Jin to east to Yanbei (northern Hebei). Later, King Wuling of Zhao "broke Lin Hu and Lou Fu in the north" and drove them to Zhaoxi. Then, King Wuling of Zhao drove Lin Hu to the territory of Yimeng (now Ordos City) and north of Yinshan; "Dresses" Lou annoyed, recruited their army. In this way, the land of thousands of miles of Lin and Lou was incorporated into its own territory, and Yunzhong and Yanmen were set up to govern the three counties on behalf of them. Moreover, the Great Wall was built from Xuanhua, Hebei Province along the Yinshan Mountain Range to the west, and directly to the gap of Wolf Mountain in the north of the Wuyuan of the present-day Hetao, so as to achieve the purpose of consolidating the land, defending Beihu, and then trying to strengthen Qin. Despite this, the Lin and Lou clans were not wiped out. More than 50 years later, when Xiao became the king, Lin Hu came with the budding Xiongnu and led the crowd, but was unintentionally defeated by Zhao General Li Mu with a "strange array", and the name of Lin Hu slowly disappeared from the annals of history. However, until the reign of Qin Shi Huang, the Hu people in the "Yunzhong" area have never been extinct, and this tribe has converged into the Xiongnu. At this time, Lou Fu was still active in the Ordos area. At the end of the Warring States Period, the Xiongnu arose, and Ordos was included in the territory of the Xiongnu, and Loufu was subordinate to the Xiongnu. Qin destroyed the Six Kingdoms, Qin regained the "Henan Land" by Meng Tian, and Lou Fu was again under Qin's rule. During the reign of Emperor Wu of the Western Han Dynasty, the Han general Wei Qing was "defeated...... After the building was annoyed, the land of Henan in the Qin period was recovered. "Since then, the building has ceased to be a country. Later, Lou annoying people scattered in the Saine, or merged into the Xiongnu, or integrated into the Han nationality, and gradually disappeared from the historical stage.

The above is a historical narrative, let's get down to business.

At this time, due to the defeat of the Xiongnu and the seizure of the hegemony in the north of the Qin State, the two tribes of Linhu and Lou Fu naturally obeyed the orders of the Xiongnu.

The Xiongnu leader Mandan Yu ordered a sweep of the villages and towns in the three northern counties of Qin, and the two tribes of Linhu and Loufu were assigned to the vicinity of Zhiyiqu County, the county of Beidi County.

When the court of the Qin State heard that the Hu people had invaded south, the crowd was excited.

King Yingzheng of Qin sent Wang Jian as the commander to the three northern counties. Wang Jian knew the power of the nomadic cavalry, and sent Wang Ben, Li Xin, Zhang Han, Meng Tian, Meng Yi and others as the vanguard, each leading 5,000 cavalry to the front.

Beidi County, which was placed by King Zhaoxiang of Qin in 271 B.C., was one of the 36 counties in the early Qin Dynasty, and governed Yiqu County (in the southwest of Qingyang City, Gansu Province).

Longxi County is named because it is west of Longshan. Junzhi Di Dao (now south of Lintao County, Gansu Province).

Shangjun is said to have been first placed by Wei Wenhou during the Warring States Period. During the reign of King Hui of Qin, that is, in 328 BC, the state of Wei dedicated 15 counties to the state of Qin. Shangjun thus became one of the 36 counties in the early Qin Dynasty, and the county governed Fushi County (now Suide County, Shaanxi Province).

The three counties of Beidi County, Longxi County, and Shangjun are close to the northern border of the Qin State, and have always been the "land of horses" fought for by the Yue's tribal alliance and the Xiongnu tribal alliance.

Since Meng Yi is in Wujiabao, Wushi County, Beidi County at the moment, it is very close to Yiqu County, the county. Therefore, as soon as Meng Tian and the others were combined, it was better to divide the troops into a group, and everyone gathered in Daowujiabao to converge.

At this time, seeing the strength of the Qin army, the three thousand Huns outside Wujiabao retreated.

"The Xiongnu invaded the south this time with more than a dozen tribes sending troops, including 50,000 troops from the Xiongnu royal court, and more than 20 tribes such as Baiyang, Zhelan, Hun Xie, Hutu, Linhu, and Loufu, each sending thousands of troops and varying in number. Now the enemy is distributed in a dozen counties on the border, with a total number of more than 100,000 people, and all of them are cavalry. Meng Yi told the basic situation, and then looked at the other four.

"What are you looking at us for? You are the first to arrive at the battlefield, and you have the most right to speak. Wang Ben shouted without shame, and the others also snickered.

"Guys, it's useless to just look at me! The nomadic cavalry came and went like the wind, and this battle was not easy to fight. The only thing to be thankful for is that these 100,000 people are only a loose coalition of tribal alliances, and have not yet formed a regular army similar to an iron fist, otherwise we would still have come from and where we will go back. Meng Yi also had a headache and complained bitterly.

"Our Qin army has nearly 30,000 cavalry troops, plus the main force of the 100,000 infantry army that has not yet arrived, if it is a simple defense, it is not a big problem. But if these nomadic cavalry retreats to the steppe, where do we go to find them? Meng Tian also interjected and reminded.

"The enemy's situation is unknown, and I think it is better to send more scouts to investigate the enemy's situation. Only by knowing oneself and knowing one's opponent can one not be defeated in a hundred battles! Meng Yi Lao Cheng suggested solemnly.

"We see it that way, too. Be careful! Wang Ben, Li Xin, and Zhang Han can also be regarded as generals who have experienced several battles, and they glanced at each other and spoke in agreement.

Five days later, the 100,000-strong army commanded by Wang Jian also arrived in Yiqu County. The 130,000 army, in addition to the nearly 30,000 cavalry led by Meng Yi and others, also included 10,000 charioteers, 30,000 crossbow men, and 60,000 infantry. Fortunately, Beidi County, Shang County, Longxi County and other county towns have hoarded grain and grass equipment, so the 100,000 army can reach the front line so quickly.

Inside the big tent of the commander of the Qin army.

"Ladies and gentlemen, in response to the coming and going of the nomadic cavalry, Ben Shuai decided to rely on the three county towns of Yiqu, Didao, and Fushi to deal with the Huns. The Yiqu is in the center, which can be the big tent of the Chinese army; Skins are on the right, which can be right-wing; Di Dao is on the left, which can be left-wing; The rest of the counties are all self-defending, and they are not allowed to fight without authorization. ”

"No!" Meng Yi also echoed.

Meng Yi thought to himself: Sure enough, ginger is still old and spicy! Since the Huns suffered Li Mu's great loss, they never fought head-on with the armies of Yan, Zhao, Qin, etc., but constantly attacked the strongholds, went around and looted, and ran away after grabbing, so that the three kingdoms of Yan, Zhao and Qin in the north were helpless!

Next, it is the contest between the big "wolf pack" of the Hun cavalry and the big "hedgehog" of the Qin infantry army!

In Wushi County, not far from Yiqu County, Qiu Linye, the leader of Linhu, and Huyan Baihu, the leader of Loufu, had a sad face.

Qiu Linye, the leader of Linhu, is a tall, dark-skinned middle-aged man with a bold personality who loves drinking and BMWs the most.

And the leader of Lou Fu, Huyan White Fox, has white hair on his temples and is over fifty years old, and at first glance he is a shrewd person who has experienced a lot of wind and frost on the grassland.

Yiqu County, as a county of Beidi County, naturally cannot be defeated. The two tribes had just swept the northern counties of Beidi County, and they were still thinking of going south to sweep the southern counties of Beidi County, but they didn't want the Qin army to march fast, so they nailed an army of more than 100,000 to Yiqu County, blocking the passage of the nomadic cavalry to the south.

"Things are a little bad, we should retreat to the grassland earlier, otherwise we will be blocked by the Qin army in the south of Liupan Mountain, but it will be miserable." Huyan White Fox, the leader of Lou Fu, suggested.

"In that case, let's gather our men at once and set off at dawn tomorrow!" Lin Hu leader Qiu Linye hurriedly agreed.

"In this way, in order to prevent the Qin army from having an ambush, the Lou Fu tribe is willing to take the lead." Huyan White Fox, the leader of Lou Fu, played a cautious eye and wanted to let Lin Hu people queen the palace.

"Okay, it's annoying to hand over to your building in front, and our Lin Hu people will ensure the safety of the back road." Lin Hu leader Qiu Linye was a cheerful grassland man, and nodded in agreement. So the people of the two tribes got busy.

At this time, in the camp of the Qin army in Yiqu County, the commander of the Qin army, Wang Jianzheng, listened to the report of the front-line scouts, and Meng Yi and other generals naturally accompanied him.

"So, the various nomadic tribes are busy evacuating?" After listening to the detailed report, Wang Qian, the commander of the Qin army, looked a little excited.

"Yes, Sir. The Hu people retreated when they saw the large number of our troops, but their reconnaissance was very tight, and it was very difficult for us to sneak attack. The Scout Lieutenant nodded in explanation.

"Meng Yi, you are most familiar with the nearby terrain, is it possible to bypass the enemy scouts and set up an ambush on the rear road?" Qin Army Commander Wang Jian turned his head, looked at Meng Yi and asked.

"Marshal, it is not possible unless you go five hundred miles away. Besides, we can set up an ambush, and so can the enemy! The last general did not approve of the expedition. When Meng Yi heard this, his head immediately grew like a fight, and he thought: When am I most familiar with the terrain? I was only five days ahead of the army! What an international joke!

"Let's give it a try, an army of more than 100,000 can't go home empty-handed." The commander of the Qin army, Wang Qian, stroked his beard and looked at Meng Yi with a smile, "Meng Yi and Meng Tian obeyed the order and ordered the two of you to immediately lead five thousand cavalry and rush to Longshan to set up an ambush in the starry night." Fear the enemy and not the former, slash! ”

"The last general will obey the order!" Meng Yi glanced at his brother Meng Yi helplessly, bowed down and agreed.

Meng Yi thought to himself: Wang Jian is worthy of being a handsome person who will sweep away the six eastern countries in the future, and his power is getting heavier and heavier! Now that Wang Ji and Duke Qi have died of illness, and their grandfather Meng Fu has also died in battle, only Wang Jian and Huan Qi are the generals of the Great Qin Dynasty. And Huan Qi is also old and decrepit, only Wang Jian is prosperous in the spring and autumn.

Therefore, among the generals of the Qin State, if you offend anyone, don't offend Wang Qian! This is a commander who is extremely strict in governing the army!

After the two brothers Meng Yi led the troops to the battle, they immediately divided the 5,000 men into ten teams, took advantage of the night, scattered to the enemy's rear, and went to the foot of Longshan Mountain to assemble.

Longshan in the distance, like a sleeping beast, will it wake up because of the battle between the two sides? Or what kind of surprise does it bring?
