Changshan, the Wei lord Min Liu's general Jiang Gan made the auxiliary prince Zhi Shoucheng, and the general Baxian Sima Qinghe Wang Ning surrendered to Wei with jujube. Min hit Xian, defeated him, and chased to Xiangguo. The great general Cao Fuju opened the door to Namin. Min killed more than 100 people under Xian Xian and his ministers, burned the palace of Xiangguo, and moved his people to Zhen.

------------- excerpt from the introduction

"King Zuo Xian, are we really going to attack Dingbian?" Cao Hub asked worriedly.

"Exactly," Liu Wuhuan replied very resolutely, "Youxian King, are you afraid?" ”

Cao Hub shook his head in embarrassment, but the still worried look on his face betrayed him, and it seemed that he was not at all sure about this attack.

Liu Wuhuan looked down on this so-called Xiongnu Right Sage King from the bottom of his heart. Cao Hub is a tribal leader mixed in the land of Henan, the previous sphere of influence is south to the upper reaches of Luoshui, north to Yanze, the east and west rivers as the boundary, including most of the land of Henan, the center is Luyanze. With nearly 100,000 people of Xianbei, Beiqiang, Xiongnu and other ethnic groups, and nearly 20,000 people who control the strings, they can barely make do in the land of Henan (the area south of the Hetao), and the Tiefu Department that occupies the Hetao area is not too far behind.

And Cao Hub's background is relatively complicated, he should also belong to the Lite people, and Shi's Hutong belongs to the Zhaowu nine surnames, but after the decline of the Xiongnu, he went to Henan, slowly annexed the nearby small tribes, and became a small tribe in Shangjun, and it was the former Wei at that time, Cao Hub's ancestors assumed the surname of the country at that time - Cao, and claimed to be the Huns. When the Shi clan stole the Central Plains, Cao Hub's father immediately defected to Shi Zhao. Shi Hu saw that everyone was a Lite person. They are all descendants of the Yue family, and there is still a bit of incense, so they gave the Cao family an Anbei general, and the title of the right virtuous king of the Huns.

After the Cao family had this title, with the support of Shi Zhao, they began to show their skills in Shangjun and went to the entire land of Henan. Soon subdued hundreds of nearby tribes, large and small, and became the powerful alliance leader in the land of Henan. After having the capital, Cao Hub's department began to gather soldiers and horses to frequently go south to "hunt". Invaded Feng Yi, Beidi (now Yaoxian, Shaanxi), and Anding Counties. Although they have done great harm to the people of Yongzhou counties. But Shi thinks it's a trivial matter. So I didn't care about the Cao family's nonsense.

Later, Shi Hu died of illness, Zeng Hua became the master of Guanlong, and Cao Hub's good days came to an end. Under the fierce attack of tens of thousands of Zhenbei troops, Cao Hub's troops no longer dared to go south, the price was too great, and the southbound troops were often wiped out without a small heart.

Cao Hub had no choice but to order his troops to move north, and strictly forbade the soldiers and horses to go south. In the seventh year of Yonghe. The Zhenbei Army, which had always been mainly defensive, actually began to counterattack. First Yan'an City, then Yangzhou, Suide, successively built, the area south of the Luyanshui was previously attached to the Cao hub land more than a dozen tribal leaders or died, tens of thousands of people and a large area of land fell into the hands of the Zhenbei army.

Cao Hub couldn't help but be furious, and led his troops to attack the Zhenbei Army, but was defeated by Lu Zhen and others one after another, and finally let the Zhenbei Army attack all the way to the north of Haoyanshui. Occupy and build the city of Skin.

Cao Hub's stealing of chickens does not become a counter-erosion of rice. He fled back to Yu Yanze with the remnants, and before he could catch his breath, Jiang Nan led more than 10,000 cavalry to roar. The Cao Hub Department has accumulated for several generations, and the local people and cattle and sheep have been snatched cleanly. Cao left behind tens of thousands of troops and countless cattle and sheep, and only took more than 1,000 remnants of horsemen to flee north in panic and defected to Liu Wuhuan of the Tiefu Department in the Hetao area.

Liu Wuhuan was also headache with the Zhenbei Army that was advancing step by step in Jincheng County and Anding County, and successively lost rich places such as Lianxian County and Lingwu, and finally even the Xiongnu Helan Department was lost in the hands of the Zhenbei Army. Moreover, the Zhenbei Army, which had established a foothold in Lingwu, did not stop there, but used Helan Mountain and Lingwu as bases to frequently attack the Houhetao area in the north.

The Houhetao area is east to Shuofang City, west to Linrong City, north to the foot of Wolf Mountain and Yin Mountain, south to Gobi Yanze, including Fertile Field, Linhe, Guangmu and other cities, it is really fertile for thousands of miles, rich and rich, and it is the tip of Liu Wuhuan's heart and liver. The Zhenbei Army attacked the north repeatedly, causing Liu Wuhuan to suffer heavy losses, but he was not beaten to ruin like Cao Hub, and finally retained most of his strength.

After receiving the embarrassed Cao Hub, Liu Wuhuan felt that there should always be an understanding of things. So he sent someone to report to his nominal boss, on behalf of Wang Tuoba Shiyi, about the "ups and downs" and "hardships" he had encountered in the past few months, hoping to get organizational instructions and help.

Soon, Tuoba Shiyi sent someone to tell him that he had taken up the position of acting king, Da Dan Yu, and the military governor of the southern and northern deserts of the Jin Dynasty, and Zeng Hua, the general of Zhenbei in Guanlong, was already a colleague, and he Tuoba Shiyi could not do the thing of meeting with his colleagues.

However, the envoy of the acting state told Liu Wuhuan that the acting king had not yet had time to present his official position to the imperial court for Liu Wuhuan, so in a sense, Liu Wuhuan and Zeng Hua were not colleagues, so Tuoba Shiyi asked Liu Wuhuan to act on the camera, and brought a large number of materials such as 1,000 good horses and 3,000 sets of armor given by Tuoba Shiyi.

Liu Wuhuan and the envoy drank all night, and finally figured out the situation in the Hedong area.

Zeng Hua of Chang'an not only sent people to find trouble with Cao Hub and himself, but also sent heavy troops to defeat Zhang Ping of Bingzhou, occupied several counties of Bingzhou, and sent troops to Yanmen and other places, defeating his distant relative Liu Kuren, killing Liu Kuren and retreating north with Dugu Gang again and again. Then Tuoba Shiyi swallowed his anger, and actually agreed to make peace with Wang Meng, the assassin of Bingzhou, and became the acting king of the Jin family with peace of mind.

Liu Wuhuan is a smart man, he knows that Tuoba Shiyi is unwilling to be the enemy of the Zhenbei Army, firstly, because the morale of the victorious division of the Zhenbei Army is high and the edge is unstoppable; The second is that the battlefield has been opened up to the Yunzhong region, not far from Shengle, the old nest of the Tuoba Department, how dare Tuoba Shiyi fight with the elite Zhenbei army at his own doorstep? The Zhenbei army was defeated, at most retreated to Yanmen or Taiyuan in Bingzhou, if Tuoba Shiyi was defeated, I am afraid that the old nest would also be ended.

Liu Wuhuan finally figured out the hint that Tuoba Shiyi gave him, go and fight the Zhenbei Army, I will support you materially and spiritually.

But Liu Wuhuan is not a fool, otherwise Tuoba Shiyi would not have been able to catch his tail for more than ten years, and let him be left and right in the Hetao area. I can't moisturize it. Liu Wuhuan will not be easily used as a spearman by Tuoba Shiyi, he has his own schemes.

Liu Wuhuan carefully studied the strategy of the Zhenbei Army passing through Beidi County and Shangjun, and soon discovered the intentions and strategies of the Zhenbei Army.

The Zhenbei Army took the west river in the west, and the Zouma River, the Haoyan River, and the East River in the east as the marching route, slowly advanced to the north, and built a city fortress after occupying a place, taking it as a basis, and slowly encroaching on the land south of the river. After killing the land of the river, you can follow the east and west of the river. In one fell swoop, he took down the Tiefu Department that was sandwiched in the middle.

What a good idea. Especially against a nomadic tribal force like his own Tiefu tribe, along the water source, you have nowhere to run, you can only retreat under the offensive of the Zhenbei army like a wall, and finally be surrounded and annihilated.

But there is a big loophole in your strategy, and that is the middle lane. Liu Wuhuan soon discovered the fatal flaw in the strategy of the Zhenbei Army.

There are not many soldiers and horses in the hundreds of miles from Luyanshui to Lingwu, although it is a little desolate. But there is also water and grass. From Hetao to the south, through Yanze, Dacheng (now southwest of Yijin Huoluo Banner in Inner Mongolia), Gaowang (now north of Wushen Banner in Inner Mongolia) to Dingbian,

The Southern Highlands (now the famous Ordos Plateau), although covered with meadows, are suitable for nomadic and cavalry marches.

After Dingbian, you will arrive at Anding County, and then go all the way south, hundreds of miles can reach Chang'an. This little road is nothing to the cavalry. In the former Qin and Han dynasties. The Xiongnu used to attack south frequently along this route. In order to protect Guanzhong from the invasion of the northern borderlands, Qin Shi Huang and Emperor Wu of the Han Dynasty once sent troops and horses to recover the northern land and Shuofang, which shows the importance and danger of this route.

Liu Wuhuan, who has read Han books, naturally knows these allusions. He studied and studied, and from more than a dozen spy intelligence, he finally determined that there were less than 10,000 cavalry troops in the middle of the road patrolling back and forth. Liu Wuhuan couldn't help but feel glad for the carelessness of Beifu, it seems that Zeng Zhenbei and his generals in Beifu only stared at the river on both sides, but forgot the Henan Highlands in the middle.

Liu Wuhuan finally decided at the end of October that he would send troops south to invade Beifu. However, Liu Wuhuan clearly realized that there were five states in Beifu, and there were millions of Xiqiang and the surrendered Longxi Xiongnu and Xianbei tribes to provide excellent cavalry resources, and their strength and stamina were immeasurable, especially compared with the Tiefu tribe, which only occupied the Hetao area and had more than 100,000 troops in name but only tens of thousands in fact, it was simply a behemoth.

Once he and Beifu fight each other, then the mountains and seas of Beifu, wave after wave of offensives, will make the Tiefu Department face a catastrophe. You see, now the Zhenbei Army is only frequently sub-divided to invade north, which has already made the Tiefu Department shout that it is unbearable, if the Beifu goes all out to the north, he really has to flee north like his father. At that time, maybe Tuoba Shiyi will exchange his head for the affection of Chang'an Zenghua's colleagues.

Therefore, Liu Wuhuan told himself that if he really wanted to fight with Beifu, he would choose a suitable opportunity to make Beifu have no power to fight back, and this opportunity was to pass through the Henan Highlands from the middle, pass through Dingbian and Anding County to take Sanfu Chang'an, and insert a knife into the heart of Zeng Zhenbei.

Although this plan is very crazy and risky, and if it is not successful, it will be counterattacked and retaliated by Beifu frantically. But Liu Wuhuan thinks so, as long as he and Beifu tear their faces and officially start fighting, the Zhenbei Army will go all out to deal with him sooner or later. Moreover, once he succeeds in his sneak attack on Sanfu and Chang'an, he will not only be able to plunder a large amount of wealth and population and enrich his own power, but will also deter Beifu and force Zeng Zhenbei to accept his own peace under the city like Tuoba Shiyi. Then he will not only keep the Hetao area, but also use the opportunity of this big victory to truly unify the Hetao area, and then annex the Henan region, then his own strength will not be able to speak soon.

What excites Liu Wuhuan the most is that once God favors him and allows him to succeed in his sneak attack on Chang'an, defeat Zeng Zhenbei or kill him, and then the situation changes abruptly, I am afraid that this Guanlong land will be owned by my Tiefu Department, and I will not have the opportunity to participate in the Central Plains hegemony. Thinking of this, Liu Wuhuan couldn't help but tremble.

Liu Wuhuan gathered more than 10,000 cavalrymen from various departments of the Hetao by various means, plus 5,000 cavalry from his Tiefu Department and 1,000 cavalry from Cao Hub, and set out from Shuofang on 29 October and quietly marched south.

But Liu Wuhuan didn't expect that as soon as his front foot came out of Shuofang, someone on his back foot galloped southward more quietly. In the past few months, the Zhenbei Xiang Army has been fighting in full swing in Beidi and Shangjun, and the Horse Scouts and Cavalry Division, who have always been unwilling to lag behind, will naturally not sit there and watch the excitement, and all kinds of spies infiltrate the Hetao with various identities and various means, and soon establish a set of intelligence networks in the Hetao area and around Liu Wuhuan. You must know that the Horse Exploration Division and the Reconnaissance Cavalry Division, which Zeng Hua consulted, are intelligence agencies armed with "advanced thinking on military intelligence work," and they are quite professional.

The army went south, all the way quickly, very smoothly. The tribes in Henan have been beaten into frightened birds by the Zhenbei cavalry that frequently attacked, and the leaders of those tribes saw Liu Wuhuan, who led the troops south, and immediately became closer than seeing their father, hugging Liu Wuhuan's thigh is a cry, saying how vicious the Zhenbei cavalry is, taking their cattle and sheep, plundering their subordinates, especially in the occupied areas, what is the implementation of the equalization system, and the abolition of tribal leaders. Since ancient times, there must be a leader in this grassland, just as it is natural that a flock of sheep must have a leader, if there is no leader, then there is no sun.

These leaders gritted their teeth and bled heavily, not only donating cattle and sheep as military funds, but also returning you 300 and I 500, providing cavalry to enrich Liu Wuhuan's team.

Liu Wuhuan is also happy to have more manpower, from Shuofang to Yanze to Dacheng, Liu Wuhuan's army has reached more than 20,000 horsemen, and he is not worried about cattle and sheep food. But in order to wait for these recruits and cattle and sheep, the speed of the march was also much slower, five days later than Liu Wuhuan expected.

After Liu Wuhuan led the army through the big city, he began to turn around and turn westward at the foot of Shiziling, bypassing the Luyanshui area where the heavy troops of the Zhenbei Army were gathered, passing Guiren Huaide, and going straight to the border.

The road was safe and smooth, and the spies scattered everywhere did not find any cavalry troops in the north of the town, only the Xianbei, Xiongnu, and Beiqiang herdsmen who were grazing in twos and threes. In order not to startle the snake, the spies of the Tiefu Department just observed from a distance, and quietly walked away without finding anything strange, and then guided the army to quickly pass through the area where there was no Zhenbei Army. However, Liu Wuhuan and the others never thought that the Zhenbei Army Cavalry was not only stronger than them in combat effectiveness, but also much stronger in reconnaissance ability. The whereabouts of the Tiefu tribe are constantly being sent where they need to go.

Seeing that everything was going well, Liu Wuhuan couldn't help but feel comfortable, and finally gave a clue to Cao Hub, he not only wanted to attack Dingbian, but also Sanfu and Chang'an to create a new myth.

Cao Hub was suddenly stunned by Liu Wuhuan's plan, and was speechless for a while.

Liu Wuhuan hurriedly persuaded this ally, who was still relatively prestigious in Henan, and said: "King Youxian, how about we attack Dingbian?" What about the defeat of the Zhenbei cavalry? With a population of millions and hundreds of thousands of cavalry, they can easily recover and make a comeback. What about you recovering Yu Yanze, how long can you hold out under the new offensive of the Zhenbei Army? ”

Speaking of this, Liu Wuhuan said with a complicated expression on his face: "King Youxian, I heard that Guan Long killed nearly 100,000 Hu, and you are ......, my lord, if it falls into the hands of Beifu, I am afraid it will be ......."

This is where Cao Hub has always been worried. He and the alley come from the same source, and naturally there are characteristics such as deep eyes. This Guan Long and the Central Plains killed the corpses all over the field, and the heads were piled up, and Cao Hub had already heard of it. Although he claims to be a Huns, but this appearance can't be changed, if it falls into the hands ......of Beifu, Cao Hub can't help but fight a cold war.

"Right Xian King, both horizontal and vertical are dead, it's better to fight. Thinking that Emperor Shi of Northern Zhao, who was born from a humble background, but made immortal achievements, wouldn't King Youxian dare to make a Bo and follow Emperor Shi? Liu Wuhuan continued.

Cao Hub was stunned for a moment, and after a while, he felt his blood rushing, he pulled out his long knife, and said fiercely: "Damn, Bo!" ”

Within a day, the Tiefu coalition army soon saw the Mugen Mountain (now south of the Etuoke Banner in Inner Mongolia, at the junction with Yanchi in Ningxia) not far ahead.
