The basic structure of the Hu and Han regimes in Pingyang basically copied the Jin system, and built a single in Taiwan outside of it, so as to control the so-called "six yi" such as Di and Qiang, and slaughter their own tribes and even the Xiongnu. Although these two systems seem to be harmonious and orderly, there are still many stumbling blocks in their actual operation.

First of all, Tu Ge, Xiongnu, although most of them are sinicized, after all, there are still many nomadic herders, and there are many contradictions between the old Jin Dynasty Shihao, and it is quite difficult to use the same set of teams to manage it as a whole, at least whether it is Liu Cong or Liu Cang, there is not enough political wisdom and patience If Liu Yuan is still there, maybe the situation will be slightly better.

Secondly, the six Yi and Qiang are now greatly reduced, and the rest are not compatible with the Pingyang regime, especially Liu Cang.

The ethnic structure of the Hu and Han regimes was based on Tu Ge as the core, the five Xiongnu tribes as the shares, and the Jin and Yi as the outsiders. That is to say, the reason why Liu Yuan was able to grow was first to slaughter the Xiongnu, and then to reconcile with the six Yi such as Di and Qiang, as well as some Jin Shihao, and form an alliance, so that he could claim the title of respect and be far from the party. When Liu Yuan was there, he originally ordered Liu Cong to be the big single Yu, and he controlled the six Yi, and after Liu Cong succeeded to the throne, he was reappointed Liu, and then changed Liu Cang, the three big orders, in fact, the former emperor's brother Liu was the most supported by Di and Qiang.

The reason is also very simple, because Liu's father slaughtered each and his mother was a person, and his mother's family was among the people of Liuyi, especially the various tribes of Sili and Bingzhou, and their power and prestige have always been respected.

Liu Yuan's first queen was Huyan, Huyan was a Xiongnu surname, this was a political marriage between Tu Ge and the Xiongnu, and his crown prince Liu He was the son of Huyan. After Hu Yanhou died, Liu Yuanjin made the side concubine Shan the queen, and the Shan family had a son first, that is, Liu.

The father of the single queen is named Shan Zheng, who was originally the chief of Shangjun, and his power is quite large and not weaker than today's virtual power canal, he officially turned his back on the Jin Dynasty in the second year of Yongjia, and the eastward minister was subordinate to Liu Yuan, and it was also in the same year that the Hu Yan collapsed, and the Shan family succeeded to the queen, whether this is a coincidence, or something strange, outsiders do not know.

When Liu Yuanxu died, Liu He succeeded to the throne, and wanted to kill his younger brothers, Liu Cong got up and fought against each other, relying on his title of Da Shan Yu at that time, and with the help of Liuyi, he could successfully kill Liu He. But after the successful coup, Liu Cong pretended to give up the throne and wanted to respect his brother Liu, why? Although Liu is young, he is the son-in-law born to the Shan family, and Liu Congben is the concubine born to Mrs. Zhang, and there is a difference between dignity and inferiority; Second, Liu, as the grandson of Shan Zheng, although he is still underage, has a high prestige among the six yi, so Liu Cong did not dare to jump on it.

Liu was not yet an adult at the time, so he insisted on not being accepted, and Liu Cong was able to practice Zuo, respect Shan as the queen mother, named Liu as the emperor's younger brother, and appointed him as Da Shan Yu and Da Situ. However, soon after, Liu Cong transferred the position of Da Shan Yu to his son Liu Can, and even made Liu Cang the prime minister, and entrusted the government of Han and Yi to Liu and Liu Cang's disharmony, and it began from then on.

There is also a saying that after Liu Congshi was single, Liu persuaded Shan Hou to be self-respecting many times, which led to the death of Shan Hou, and Liu Cong's brotherly relationship between Liu Cong and Liu came to an end.

In the original history, Liu Cang repeatedly begged Liu Cong to depose Liu Cong and establish himself as the crown prince through Jin Zhun, Wang Shen and other traitors, but Liu Cong refused. So Jin Zhun and others set up a conspiracy and set a trap to frame Liu for rebellion, first killing dozens of his close ministers and officials and subordinates of the East Palace, and then deposing Liu as the king of the north, and finally murdering him, and killing more than 5,000 people in Pingyang who were attached to Liu, of which half of them were Di and Qiang chieftains, so that "more than 100,000 Qiang rebels fell", accounting for almost half of Liuyi......

And on this timeline, Liu was forced by the situation to conspire with Liu Yao, planning to kill Jin Zhun and Wang Shen "on the side of the king", but was defeated by Liu Cang, and naturally lost the throne of the emperor's younger brother in advance and was imprisoned. After Liu Cang and others stabilized the domestic political situation a little, they also got rid of Liu and killed his wives and concubines and children in the spirit of cutting the grass and eradicating the roots, as in the original history. History develops according to its inertia, and there are many rebellions in Di and Qiang.

Originally, in history, Liu Cang ordered Jin Zhun to quell the rebellious Liuyi, but in this timeline, because Taiyuan County in the north had been obtained by Shi Hu, most of the rebels and rebels fled north to attach themselves to Shi Hu. Liu Cang ordered Shi Hu to hand over people, but Shi Hu always took care of the left and right and said that he and I had eaten it, and you still insisted that I vomit it, how can there be such a beautiful thing in the world?

In this regard, almost half of the Yi tribes that the Pingyang regime could actually control were reduced, and most of the rest were also yang and yin, secretly obstructing Liu Cang's administration. As a result, Liu Cang wanted to gather troops, horses, and materials to launch an attack on Guanzhong, but the order was given, but there were many obstacles in actual operation, resulting in a long delay, so that he could not catch up with the pace of Peng Fuhu and Liu Hu's invasion......

Pei Gai has a deep understanding of this political situation within the enemy country, one of which comes from the investigation of Pei Xu and other spies, and the other comes from the insight of later generations. In the original history, the decline of Hu and Han eventually led to Liu Cang's murder by Jin Zhun, and its root cause can be traced back to this Yibu rebellion, and although history has been changed to a great extent, as long as you Liu Cang dared to kill Liu before ascending the throne, the ending must be similar.

In addition, the Jin people in Hedong, Shihao, headed by the Xue family, had already secretly communicated with Pei Gai about Liu Can's plan to move troops after the autumn, and Xue Tao sent someone to report it secretly at the earliest. Most of the wealthy Jin families did not get the order to send troops to conscription, but if Pingyang wants to launch a large-scale foreign invasion, they will definitely ask them to send and donate food, so as long as it is delayed for a few days, it will be convenient for the Jin army in Guanzhong to take precautions.

Therefore, Pei should say that the operating mechanism of Pingyang, a hundred-legged insect, has actually been completely ossified, and there is no need to worry.

According to the report from the sentinel, the soldiers and horses of Tu Ge and the five Xiongnu departments are gathering in the direction of Caisangjin one after another, which is not unexpected by Pei Gai and Tao Kan.

Feng Yi County is adjacent to the Pingyang regime, and there are many traditional ferries on the Yellow River, such as Puban, Yang and Xiayang, and the west bank of the river is a plain, which is convenient for crossing. But because these three are traditional agricultural areas, they are all guarded by large towns, and after the expulsion of Liu Yao, Tao Kan also set up a number of forts around the ferry, and the defensive posture is definitely beneficial to the Jin army.

One hundred and eighty miles to the north from Xiayangdu, there is no Sangjin, and the river channel is narrow, resulting in turbulent water flow, and there are mountains on both sides, which is actually not suitable for the army to wade. However, it was already out of Feng Yi's county boundary, and it was beyond the actual control of the Jin army, so Liu Cangda could spend a long time surviving the army peacefully. If the Jin army goes north, trying to stop it, or even hitting it halfway, it will be very far away from the core area, and the road is dangerous and narrow, and it is difficult to ensure that the road itself is smooth.

Therefore, Pei Gai and Tao Kan originally expected that Liu Cang might cross west from Caisangjin, and summon Liu Yao to join and invade the south. It's just that I didn't expect Liu Yao to send Liu Hu to come first, and it is estimated that Liu Hu will eat Gao Nu's grain storage this time, so whether Liu Yao still dares to come will be marked with a big question mark.

If Liu Yao dared to lead the newly defeated soldiers of the high slaves who were demoralized and had no food to follow, and really ran to meet Liu Cang, maybe Liu Cang would annex this army on the spot, and Liu Yao would probably become a prisoner.

However, if the Hu army crossed west from Caisangjin, because of the terrain restrictions, it was impossible to go directly south along the west bank of the Yellow River, and it was necessary to detour back to the west of Liangshan first, and go south through the Shangluoshui River valley was basically the road where Liu Hu was finally defeated, and it was also the east road where Tao Kan planned to advance and build forts. This great detour is not less than 500 miles before it is possible to approach Suyi, unless it can be carried down by a drum, otherwise considering the problem of grain transportation, the army will stay for a maximum of ten days, and then be forced to return with a feather.

It can be inferred from this that it is impossible for Liu Cang to cross the river from a ferry farther than Caisangjin, nor can he go farther than Suyi to fight the northern land and even settle down. Even, it is impossible for him to send more than 5,000 soldiers and horses to Caisangjin and Suyi!

Unless Liu Yao, who can get a high slave, will continue to supply grain and grass, but that possibility is very small Liu Yao can't get it, and even if the grain is sufficient, there are eighty percent who refuse to give it.

Therefore, there is a possibility that Hu Jun will go to Caisangjin, but it is not high, and it is more likely to fall on the three ferries in the south. Pei Cai asked Tao Kan: "Could this be a plan to attack the west?" ”

For preventing Hu Jun's westward crossing, Tao Kan had already come up with a number of strategies and reported to Pei Gai, but in response to the change in the situation, he had to analyze it in detail in person. So he put his hand on the map and said to Pegai:

"If Liu Cang's army picks Sangjin by itself, it can summon Liu Yao and Liu Hu from the north, and take their stored grain, and try to quickly conquer Suyi. Once Suyi is down, the Hu army can enter the peace and seize the new valley in our countryside, which can be maintained for a long time. And from the east of Suyi, you can attack my Xiayang, Yang, and even Puban's ferry in many ways, as long as you open up the ferry, and then transport grain from Hedong, it will not be difficult.

"However, Liu Hu was newly defeated, and Liu Yao was unable to fight again...... "Liu Yao sent Liu Shu to lead a thousand soldiers and horses to be Liu Hu's guide, and was left at least forty percent by the Jin army on the battlefield, and it can be seen from the mouth of the captives that Liu Yao also lost a lot of military rations to Liu Hu, and it is estimated that he will not be able to get any richer" If Liu Cang crosses from Sangjin to attack Suyi, the chance of victory is slim. According to a certain speculation, if Liu Cangguo wants to go west to collect Sangjin, or change his path due to the change of situation, it will only be a false alarm for me; Or take the opportunity to go north to Gaonu and Liu Yao's subordinates, and seek a place in the old Han Shang County, and I will not be able to attack me in a short time......"

Pei Gai nodded again and again, and said, "In this way, either I am not injured, or I am indeed a suspicious soldier." ”

Tao Kan stretched out his finger and analyzed the past along the middle section of the Yellow River depicted on the map, from north to south, one ferry after another: "If Liu Cang is a plan to attack the west from the east and attack the west, he may cross the river from Xiayang, then if the ferry cannot be defended......" Although Tao Kan built many forts near the ferry and left troops to garrison them, no one can guarantee that the Hu people will be 100% blocked. Because he also had to take into account the defense of the other two ferries, it was impossible to bet all his troops on Xiayang, and the enemy would be outnumbered, and if the Hu army fought desperately to cross regardless of casualties, the gap was still very likely to be opened.

“…… If the ferry cannot be guarded, Hu will enter the flat to cut off the summer sun. It must be known that the place is adjacent to the river in the east and the ridge in the west, and the widest part is less than 20 miles, so if Liu Cang sends an army to seal the mouth, Xia Yang is in danger. If I am Liu Cang, I should take Xiayangdu as the best policy.

"Fortunately, the Xue family is in Fenyin and Dongting, which are separated by a river in Xiayang, according to the clouds, if the Hu army gathers, it will be difficult to escape its ears and eyes.

"The next strategy is to cross from Yang, and take Pingchuan directly, then I will Sheng Chen soldiers and horses in Yang, Dali to attack it, it is not difficult to break it. Zhongce came from Pusaka to cross, confronted the main force of our Dali rear army, and threatened Weishui.

It's just that it is still unknown what strategy Liu Cang will take. If I divide my army to resist, my strength will be thin, and if I join forces in one place, I will be ravaged by them when they cross the river and go down to the plain, and the fields and villages will be ravaged......"

So Tao Kan finally came up with the countermeasure: "I will send the main force north to Shouyang to echo Xia Yang." Da Sima asked to quickly summon the soldiers and horses left behind in Chang'an, stationed in Dali, and then ordered the 'Qiji Battalion' to cruise between Yang and Dali, so that it may be possible. ”

Pei should say okay, then Tao Jun, you should quickly mobilize the soldiers and horses, and I will go directly south to Dali to summon Chang'an to stay behind the soldiers and horses.

Tao Kan hoped that the Hedong Xue clan could pass the news in time, and at the same time, Xue Tao, the eldest head of the Xue clan, was teasing his child who was not yet a year old in his own courtyard near Dong Ting, thinking about the Jinhu war that might come soon.

On the one hand, Xue Tao sent people to secretly cross the Yellow River to inform the Jin side, and on the other hand, he greeted Pei Shuo and other patriarchs, not to make a hard top, under the pretext that Xingu had just been harvested and was being put into storage, and it was not easy to transfer it, so it was delayed for ten days and half a month, so as to delay the actions of the Hu army.

At the same time, he also stepped up the construction of a fortress near Zhuangyuan, just in case the Hu army actually wanted to attack or even annex the Hedong families in the name of asking for food, then he would be forced to take the initiative to raise a counter-flag; And if the Hu army marches west to Guanzhong and loses its troops, maybe he will have the opportunity to simply pull the flag and become independent.

It happened that his brother Xue Ning came over and asked: "The northern fortress will be completed, so brother should give it a name." Xue Tao thought about it, looked at the son in his arms, and said with a smile: "Even in the name of this son, it is called 'Xue Qiangbi'." ”

Before the words fell, the servant came to report, saying that the county had sent someone again, who seemed to be the newly appointed county lieutenant himself, and dozens of people, who were high-spirited, and called the door outside. Xue Tao had no choice but to put down his son and ordered: "Prepare a banquet and entertain the nobles, and I should also go out of the village to welcome you." ”

He straightened his clothes, came to the gate of the village courtyard to take a look, only to see dozens of soldiers leading their mounts to stand tall, the first one, quite tall, very healthy, not very old, similar to himself, only in his early thirties, but look at the bearing, not extraordinary...... Could it be the son of Tu Ge or the noble chief of the Huns?

You must know that although Hu Han is a joint regime of Tuge, Xiongnu and Yi, Qiang and other Yi tribes, but the people in high positions are often the first two tribes, especially Tuge, not to mention that half of the Tai people in the court are surnamed Liu, and even the guards in various places are mostly Tu Ge nobles.

Xue Tao didn't dare to slack off, so he hurriedly bowed down to greet the general, and reported his name: "Xue Tao, the grass people, I don't know if the noble person is ......"

The general let go of the reins, hurriedly stepped forward, grabbed Xue Tao's arm, and laughed loudly: "There is Mr. Lao Xue to greet him." Mr. Xue's name, I have already heard of it in Pingyang, but unfortunately Mr. Xue refuses to serve me as an emperor and I am not someone else, and now His Majesty's eldest and crown prince Liu Cang is also! ”u
