Liu Bao is already very old, and on the grassland, when the wolf king is old, he will naturally be replaced by a new, strong young wolf king.

Fortunately, the new wolf king is Liu Bao's son. Moreover, he has been a hostage in Luoyang for a long time, so he has received a high degree of influence from Han culture, and Liu Yuan, who pays attention to the fact that things must be done justly.

As a generation of heroes who sounded the death knell of the Western Jin Dynasty on the historical plane, Liu Yuan knew very well that the Great Sima of the Han State was deliberately forcing the left and central parts of the Xiongnu to openly stand on the side of the Jin State, so as to achieve the goal of completely eliminating the Huns. It's ridiculous that Liu Meng didn't know it because he was in a big position: If the left and middle parts of our Huns are gone, can your right part still exist alone?

Originally, according to Liu Yuan's thoughts, don't look at him being loyal and courageous in front of Sima Yan, but in fact, what he wanted was that after returning to Bingzhou, he would try his best to ride the wall between the Han and Jin dynasties. But the current situation ...... Hey, is there any other choice than to stand on the side of the Jin Kingdom with the banner on?

In December 272, after nervously communicating and liaising with Luoyang, Du Pre, Wang Jun, Sima Gui and others stationed at the northern end of Shangdang. Liu Yuan ascended the throne of the Great Xiongnu Zuoxian on December 3 in Pingzhou County, Xihe County. At the same time, Sima Yan issued an order to canonize Liu Yuan as the king of loyalty and righteousness, carry out the Xiongnu Dadan, and lead the five Xiongnu. After Cao Cao divided the Xiongnu into five, the Xiongnu, at least nominally, had the sole leader recognized by the Central Plains regime.

After raising the army, the Huns quickly gathered 30,000 cavalry, and recruited people from all over the country to concentrate on Pingzhou County.

Pingzhou and Du pre-stationed Sheepshead Mountain, basically the same latitude. And Wang Jun and Sima Gui are located on the cotton, directly below the sheep's head mountain. Therefore, when these three points are connected, it is a typical high-waisted right triangle (the angle of 60° is below).

And what about Jiexiu, where Guan Yi is? Well, let's say that the flat week is A, the sheep's head mountain is B, and the cotton is C. Then Jiexiu is at the midpoint of the AB line (set to D).

Now, between AD, there is a river valley basin, and there is a big river in the middle: Fenshui. Between the BD, are the mountains. Guan Yi wanted to attack Du Pre, between D, is the Loess Plateau and a small number of mountains. Among them is a famous mountain: Boundary Mountain.

Therefore, this Liu Yuan's courage is really big! How dare you raise troops in Pingzhou? I can't fight the other two places because of the geographical location, and you don't dare to raise troops here without any dangerous terrain? Isn't this a beacon for me to hit you first?

"Humph! How dare you do this? Uncle Fang, beat the drum and gather everyone to come to the meeting! ”

"No!"

With Guan Yi's order, Zhao Yi, Ju Ning, Jiang Su, Huangfu Min, Wen Hu and others all came to the big tent.

"Gentlemen, this is the case. In about ten days, our troops in Taiyuan County should be able to arrive with the whole division, and by that time our strength will be 120,000. Then add the 10,000 cavalry of the Right Xian King, a total of 130,000 people. As for the enemy army, after adding Liu Yuan's strength, it is about 160,000 to 170,000. This battle can be fought! ”

"Good! Da Sima, since he sent troops in August this year, it has been almost five months, and he has fought such a battle in Jinyang, and it is extremely unpleasant, this war, I didn't say it, please use my Juning as a pioneer! ”

"Well, ladies and gentlemen, our army is slightly inferior in terms of strength. But we had the advantage that 130,000 men were gathered in a circle, not scattered in three points like the enemy army. Therefore, the strategy of our army is very clear, concentrate superior forces, and first kill one of the enemy troops. ”

"Da Sima's words are the right way!"

"Then, when the superior forces of our army are concentrated at a certain point of the enemy's army, the remaining remaining troops will inevitably be besieged by the other two superior forces of the enemy. Therefore, the troops of our army that remain in Jiexiu are very important. Well, Uncle Fang, in the past month or so, how have you improved the city defense of Jiexiu County? ”

"Uh...... Da Sima forgives his sins. The city walls of Jiexiu County have been in disrepair for a long time, and many places have collapsed. The subordinates did their best, but they only repaired all the walls and strengthened the location of the city gates. As for the construction of exterior walls, fortresses, etc., they have not yet been completed. ”

"I don't blame you for this, after all, Jiexiu is in the interior of Bingzhou, and there has been no war for hundreds of years. It's just that this city wall ......" After knocking on the table, Guan Yi said: "Let's talk about the garrison candidates first, who wants to stay in the city?" ”

Guan Yi said this, and it was really everyone at the meeting who frowned: It's not that everyone is greedy for life, afraid of death, and afraid of difficulties. It's that this work is really not easy to do: if you don't hold it, it's small for you to be defeated and die. The main force that went out to attack lost food and grass and the rear road, and it was a big deal that led to the collapse of the whole army. And this is the rest of the city? Listening to the words of the military commander, it seems that the city defense is not very perfect.

"Hey~~" With a long sigh, Huo Zai stood up: "Da Sima, leave this matter to your subordinates." This city wall has been repaired by his subordinates, and his subordinates know best where there is a problem. Therefore, subordinates are the best candidates to defend the city. ”

"Well......" After a little longer test, Guan Yi said: "Uncle Fang, I will leave you 60,000 people." I took 70,000 people to Pingzhou. One month at the earliest, and back in three months at most. ”

"Good, Da Sima, my subordinates have a request."

"Please."

"Huo Biao, the son of his subordinates, is now in the army, please leave him behind and assist his subordinates in defending the city."

After Huo made this request, everyone present had a strange face. Because, this requirement is very unruly: the father and son are in the same city, if the city is defeated, wouldn't it be the Huo family to cut off their children and grandchildren? If you want to surrender, won't you have no distractions (does Guan Yi dare to kill Huo Yi)?

But after thinking about it for a while, Guan Yi laughed: "Yes." ”

"Thank you Da Sima for your trust."

"Trust is one thing, and more importantly, I have seen very clearly in the past month or so that Ziming has helped Uncle Fang a lot in the repair of city defense. If Ziming is left behind, the father and son will be of the same heart, and they will definitely be able to keep Jiexiu. ”

After saying this, Guan Yi turned to Zhao Yi and said, "Guowei, you will sneak out of Jiexiu City immediately, and I will ask Liu Meng to send a guide to you." You go to Luliang Mountain and bring out the 30,000 people of our army who are protecting the grain route in the mountains. From west to east, he assisted his brother in encircling and annihilating Liu Yuanhai. ”

"Brother? What do you mean by that? ”

To tell the truth, for Guan Yi's firm and clear support for Liu Meng's ascension to the throne, Ji Han in all aspects, except for Liu Chen, who had been educated by the traverser, expressed his understanding and full support, other aspects of the senior generals had doubts in their hearts.

In their opinion, the main enemy of their country at this time was the Jin state. For foreign races, we should try our best to appease and win over. As far as the Xiongnu tribe is concerned, yes, Liu Meng has helped us a lot, but we have also compensated him in terms of money and food. Even if Liu Meng is a fool, the Huns will be able to control us at that time, but there is no need to make a position clear now! No, he forced Liu Yuan's father and son to the side of the Jin Kingdom.

The rise of troops in the left and central part of the Xiongnu was not simply a matter of adding 30,000 light cavalry to the Jin State. It is the location of the Huns at this time: the West River! From here to Luliang Mountain, it is extremely convenient! And in Luliang Mountain, 30,000 soldiers and more than 60,000 people are struggling to transfer grain and grass every day! Although Jiang Wei's side has now opened up the grain route of the northern line to support the middle line, Jiang Wei's side also has to consume it, right? Why can't you temporarily make a false accusation to Liu Yuan's father and son?

"Forcing Liu Yuanhai to raise troops, so that my Han can take advantage of this war to greatly weaken the Xiongnu, is the established national policy of my Han Dynasty (the emperor and the ministers agree on it, it is the national policy). Having lost this opportunity, it would be extremely difficult to weaken the Xiongnu after the war. Therefore, although this has added a lot of unnecessary trouble to us, otherwise, it cannot guarantee the long-term peace and stability of our Han Dynasty. ”

"The younger brother still doesn't understand, but since the elder brother insists on doing so, the younger brother resolutely implements the elder brother's will. Please continue, brother. ”

"Well, Liu Yuanhai, both civil and military, and a master! Once such a person raises an army, he will not be stupid enough to stay in Pingzhou and wait for our army to enter and suppress it. So, we will definitely chase it on the West River Grassland for a long time. In this way, the 70,000 horses of our army are not too much. Therefore, the 30,000 people who needed to go down to Luliang Mountain also went down to Shandong. In this way, the east and west can be encircled, and Liu Yuanhai can be eliminated as soon as possible, and only then can he return to help Fang Bo as soon as possible. ”

"Brother understood. It's just that as soon as these 30,000 people are withdrawn, our army's grain road in Luliang? ”

"Our army has reserved nearly two million stones of grain and grass in Taiyuan County, which is enough for more than half a year. As long as we annihilate Liu Yuanhai's troops during this time, wouldn't it be good? ”

"No! Let's go! I will definitely lead the army to join my brother as soon as possible. ”
