Jilusai, located in the northwest of Dengkou County, Shuofang County, in the southwest section of the Wolf Mountain, the south mouth of the Harunge Gorge, the canyon runs through the north and south of the Wolf Mountain, the valley bottom is flat, the north is the Great Wall of the Han Dynasty, the east is adjacent to Tu Shenze, it is the northwest department of the Han Dynasty, it controls the traffic throat that crosses the Wolf Mountain, the Western Han Dynasty began to place the plug, the city is built on the cliff, it is made of stone, it is square, it stands on the west side of the gorge, it is located on the high ground on the west side of the mouth of the Halonai Valley, it is about four zhang higher than the valley bottom, it can be said that it is easy to defend and difficult to attack the dangerous pass.

Since the Eastern Han Dynasty abandoned Shuofang County to Linrong, Jilusai has actually lost its original role and has become a dilapidated small city, in which only some descendants of hopeless Han garrison veterans remain here, making a living by trading with the Xianbei people and the Huns.

The pioneer Tai Shici led 20,000 horses into this fortress and immediately renovated and improved the dilapidated city wall here.

At the same time, Xu Huang led 20,000 horses to enter the Gao Rong Pass, Gao Rong is a gap in the northwest of the Yinshan Mountain Range in Bayannur, the shape is like a door, so there is this name, it is rumored to be the end of the Great Wall built by King Zhao Wuling, and it is an important pass of the Great Wall of Qin and Han Dynasties, the Jin Ge Iron Horse of the Qin Emperor and Han Wu repeatedly went out of the Wolf Mountain to attack the Xiongnu in the north from here, but when the Eastern Han Dynasty gave up these passes for two hundred years, there was a barren grass here, because the Huns and the Xianbei people were not interested in defending here, they preferred the nomadic life of migrating by water and grass.

Tai Shici personally urged the people to repair the chicken and deer stoppers.

He constantly inspected the repair of the walls and gave guidance based on his own experience.

A soldier asked, "General Taishi, why do you attach so much importance to this chicken deer stopper?" There is really nothing to be gained in this tattered pass. ”

Tai Shici turned his head and looked at this soldier who joined the army, it turned out that he was a military cadet who came out of the Central University Hall Military Academy, and he had never had a military career before, no wonder he would ask such a simple question.

Tai Shi Ci knew that the lord attached great importance to these military cadets, so he did not be as cold as the general army officers, and patiently explained: "In the previous dynasty, the Xiongnu land was placed in the northwest of Shuofang County in Yuting alone, and we sent troops to attack the Xiongnu across the Yin Mountain, so we had to go through the routes of Dingxiang, Yunzhong, Wuyuan, and Shuofang, and attack from Shuofang, and cross the main passage of Yinshan, which is this Jilusai, from which it is forty miles to the north, it is the dam ditch, and then go north, you can cross the Yin Mountain and enter the Mobei area. This chicken deer plug is a shortcut from Shuofang to Mobei. ”

The soldier suddenly woke up: "It is said that the Xianbei Tuoba Department occupies the hometown of the Xiongnu, and that Tuoba Jiefen goes south, and he also has to pass through Jilusai?" ”

Taishi Ci said kindly, no wonder the lord values these military cadets so much, although they have no experience, they are smart and witty, can draw inferences from one another, and grow up quickly, which is much stronger than those veterans who can't read a single word.

Tai Shi Ci said in a deep voice: "A hundred years ago, the generals Dou Xian and Geng Bing led 8,000 elite horsemen, came out of the fortress from here, attacked Mobei, and beat the Northern Xiongnu to the point of embarrassment and fled. How could General Dou Xian be impeached by the traitor Yuan An, and was feared by the saints at that time, and was forced to commit suicide. Now, all this will change, and our lord will take us out of the fortress from here, defeat the Xianbei people, and make the Hu people dare not graze horses in the fortress again. ”

A few days later, Wei Yan personally supervised the army and came to Jilusai.

Wei Yan enters the city from the only south gate, climbs the city wall along the stone road, looks around, the north is steep and steep, majestic and magnificent, the front of the mountain is empty and open, the flat river is inclined, and the east of the stone city, the valley mouth is open, there is no obstruction, the passing cars and horses and pedestrians, at a glance, it is very easy to hold. The east wall of the stone city is the most dangerous, it is built close to the edge of the high steps, this terrace rises from the bottom of the valley, the wall stands like a wall, up to six zhang, plus the stone wall two zhang high, the total is as high as eight zhang, if there is no special equipment, it is absolutely difficult to climb. The top of the wall is about one zhang and two feet wide, and the base of the wall is about one zhang and eight feet thick. The four corners of the city wall protrude outwards by more than eight feet, resembling a corner tower platform; If you set up an ambush here, you can monitor and block the enemy who sneaks up from below the city. The building materials are all natural flakes of stone, the stone cracks are plugged with mud, and the outer surface of the city wall is neatly built, but due to the erosion of wind and rain for many years, the top of the wall has collapsed in many places, and it has been repaired by Tai Shi Ci.

Wei Yan stood on the chicken deer stopper, thinking of an eternal beauty, Wang Zhaojun.

In the third year of Emperor Xuan of the Han Dynasty (51 B.C.), the Xiongnu called Han Evil Shan to enter Chang'an for the first time, and Emperor Xuan of the Han Dynasty ordered two thousand horsemen from seven counties along the way to welcome. Shan Yu arrived in Chang'an and was treated with special courtesy by Emperor Xuan. When it returned to Mobei from Chang'an, it was through the Jilusai through the Yin Mountain to the north. The Han Dynasty not only sent troops to escort it, but also turned around the side of the grain and rice to give him food. Since then, there has been a prosperous and peaceful scene of "no trace of the resumption of troops for more than 60 years", "there has been no fireworks for several generations, the people are blazing, and the cattle and horses are wild". In the first year of the Western Han Dynasty (33 B.C.), Shan Yu re-entered the court, the Yuan Emperor harem queen Zhaojun gave Shan Yu, Zhaojun accompanied the single out of the Sai, that is, from the Jilu Plug through the Halonggnai Gorge, to Mobei, Hu Han Evil Shan Yu and Wang Zhaojun returned to Mobei, because of internal disputes, they both had to live in the Jilu Stone City for eight years.

Lu Su climbed to the head of the city of Jilusai, and the communication with the border Han people in recent days has eliminated his previous knot, he completely agrees with Wei Yan's ethnic policy, and his heart must be different if he is not of my race, if he can't be sinicized, he must be strongly suppressed.

Lu Su carefully studied the map of this area, and said to Wei Yan with a smile: "The lord is here in Jilusai, I expect that Tuoba will definitely come to Jilusai, and our army has attacked dozens of Xiongnu tribes in Hetao before this, and it is very tired, and Tuoba Xianbei has not fought before, so it is not the best strategy to wait for work, whether it is a field battle between the two armies or blindly defending this Jilusai." ”

Wei Yan smiled and asked, "Presumably Zijing has already made up his mind, please tell me in detail." ”

Lu Su took out a map, pointed to a place, and said to Wei Yan: "Lord, from the Tuoba tribe to Jilusai, we have to pass through this dam ditch in the middle, so it is better for us to ambush the opponent in the dam ditch." ”

Twenty miles north of Jilusai, is the mouth of the dam ditch, where there is also a stone city that echoes with Jilusai. In the north and southwest of Jilusai, whenever there are twists and turns in the valley or there are deviations, there are beacons, and the approximate distance between the beacons varies from one to two miles. These beacons and Jilusai, Dabagou Shicheng together formed the Western Han Dynasty to defend the military defense line of the Hetao area, the establishment and prosperity of the three counties of Linrong, Yaohun and Sanfeng in Shuofang County of the Western Han Dynasty are inseparable from the strong military defense line in the area of Jilusai, how can the Eastern Han Dynasty give up all here.

Wei Yan shook his head lightly: "We used a plan to burn the Xiongnu coalition army, presumably that Tuoba already knew about it, he will definitely guard against our strategy, we are just ambushing in the dam ditch, I'm afraid he will see through." ”

Lu Su thought for a moment and said with a smile: "That Tuoba has just migrated to the hometown of the Xiongnu from Beihai, and they don't know the details of the lord and the Wei army, so we might as well send a team of men and horses to meet the Tuoba Department first, only defeat and not victory, and lure the Tuoba Department into our ambush circle." ”

Wei Yan looked at the 20,000 Hun cavalry that had just been newly recruited, although the Huns were all very strong, but they were used to a nomadic life, uninhibited by nature, no sense of discipline, loose and loose, although their main general Xu Huang was good at governing the army, but they could not let them be reborn in a short time.

Wei Yan pointed to the 20,000 newly formed Hun cavalry: "Why bother to defeat, let's really lose, send 20,000 cavalry to test it and consume the combat power of the Xianbei cavalry." ”

In the past few days, Tuoba Jiefen, the head of the Xianbei Tuoba tribe, while rectifying the strong men of the tribe and preparing to go on the expedition, sent people to probe the details of Wei Yan's Wei army, and the results of the investigation made him very frustrated, and he began to feel that Wei Yan was not easy to mess with, and his heart was full of regret.

But the bold words at the Western Xianbei Touren Conference have been said and cannot be taken back, and the Western Xianbei Lord has also issued a formal order to him to send troops, so he can only bite the bullet, bring all the young and strong men of the entire tribe, and lead the army to Jilusai.

On this day, the 40,000 cavalry of the Tuoba Department arrived at the mouth of the ditch on the north side of the dam ditch, the dam ditch is the old road of the Yellow River in the past, the Yellow River has been diverted to the east hundreds of years ago, but the ditch has become the only way for the Huns and Xianbei people to pass through from Mobei to Shuofang County, there is no road here, there are more people to walk and it becomes the road, the bottom of the ditch is very flat, the horses gallop, it is very bento, the only thing to worry about is the river valley on both sides of the dam ditch, the grass is dense, if Wei Yan ambushes thousands of troops and horses here, Tuoba Jiefen and all the young men of the tribe, If it is ambushed, the Tuoba Department is finished, and it is known that Wei Yan likes to ambush enemy troops the most.

Tuoba Jiefen sent scouts to climb the slopes on both sides of the ditch and investigate carefully.

Tuoba Jiefen himself commanded most of the men and horses, and marched slowly.

As soon as the scouts sent by Tuoba Jiefen climbed the slopes of the ditch on both sides, they saw a large group of cavalry rushing to the south side of the dam ditch, without a flag, and looking strange and inexplicable, which was a little different from the ordinary Han Dynasty cavalry, but for a while, they couldn't see the difference, because these cavalry were indeed wearing Han armor.

As the first general, the face is like bronze, silkworm eyebrows and deer eyes, short hair under the chin, majestic and mighty, galloping, wielding a big axe, shouting: "Xianbei wild dogs, dare to come to the Han to forage for food!" ”

Tuoba Jiefen was furious, and hurriedly sent the warriors of the Tuoba Department to challenge the Han generals on the opposite side.

The warriors of the Tuoba Department couldn't make three moves, and they were hacked to death by the opposite Han with an axe.

The Han general on the opposite side took advantage of this big victory, and shouted loudly: "Chong, cut Xianbei and reward ten acres of pasture, cut Xianbei and reward one hundred acres of pasture!" ”

Tuoba Jiefen felt very strange, why the reward offered by the Han general on the other side was to reward the pasture.

Xu Huang, who was armed with a Xuanhua axe, led 20,000 Hun cavalry and went straight to the 40,000 Xianbei cavalry led by Tuoba Jiefen.

Tuoba Jiefen is worthy of being the ancestor of the later Northern Wei Emperor Wu Emperor Tuoba Tao, although he is a barbaric nomadic background, does not understand the text, but also has no teacher, knows the art of leading troops to arrange the formation, he Tuoba Department can stand out from dozens of Xianbei tribes together with the Murong Department, and establish so many countries later, and Tuoba Lin, Tuoba Jiefen, Tuoba Liwei and other military attainments are inseparable, Tuoba Department under their leadership, brave and good at fighting, combat effectiveness in the current Xianbei tribe is absolutely among the best.

Tuoba Jiefen had long expected that the Han army would come out of the city to engage in battle, and he unhurriedly sent the most elite cavalry in front of the battle to meet the Han army.

When the Hun cavalry first started, it was still quite imposing, but once the two armies met, they quickly fell behind.

If the 20,000 Southern Hun cavalry is led to deal with the general Han army, it is okay, but for the Xianbei cavalry, it is a bit of an egg to hit the stone, because since the Xianbei Great Khan Tanshi Huai was born, the Xianbei people have been pressing to fight the Southern Huns, the Southern Huns have been facing the Xianbei people for many years of psychological disadvantage, originally they saw Xu Huang kill the other party's general, morale was greatly boosted, but once they rushed to the Xianbei people's position, they saw the Xianbei cavalry more fierce and more confident than their appearance, they did not feel soft hands and feet, It's like a Japanese meeting an American.

After Xu Huang killed the Xianbei general, he shouted and rushed to kill, then turned his horse and swept to the side to see the Hun cavalry and the Xianbei cavalry hedge.

The results are self-evident, this group of newly formed Hun cavalry is not the opponent of the Xianbei cavalry at all, plus the Hun cavalry only has 20,000 horses, the Xianbei cavalry has 40,000 horses, the Hun cavalry has experienced the defeat of Qingyan Mountain, their military spirit has not yet recovered, and the one-sided situation soon appeared.

Tuoba Jiefen could see that this group of enemy troops turned out to be the Hun cavalry who surrendered to the Han Dynasty, and he couldn't help but be furious and said: "You Huns are traitors to our grassland children, you are a pawn for the Han people, what face do you have to meet the Kunlun God?" ”

Tuoba Jiefen's bitter accusations made these Southern Huns speechless, did they want to tell Tuoba Jiefen that their wives and children, livestock and property were under the control of Wei Yan's Wei army.

Wei Yan will run a mature administrative system to the grassland, any twenty miles radius will build a dock fort, set up a Han pavilion chief, command the township soldiers, every ten pavilions set up a county, by the Han county lieutenant to lead the county soldiers, every ten counties set up a county, by the Han county lieutenant to lead the county soldiers, each county town also has a battalion of Wei elite cavalry, such a county, county, pavilion three levels of administrative and military governors are Han people, each level of the army in the army above the commander of the officers are Han, what can they do with the Huns, was held by Wei Yan, and could only be driven by Wei Yan.

The current Huns have just been reorganized into an army, and they have not yet been joined by the Wei army at all levels to do ideological work, have not been brainwashed, and have not had time to sinicize, so they still have the idea that they are Huns and children of the grassland, so when they heard Tuoba Jiefen's words, their morale began to be a little low. 10
