Xianbei, the origin is no longer reliable, it is said that it is after the Donghu people.

However, the change of power on the grassland is very frequent, and it has nothing to do with national inheritance and transformation, customs, or bloodline. The names of later generations include Donghu, Xiongnu, and Xianbei, which have been annihilated in the long river of history, and even those that are not known to the people of the time.

Xianbei really began to enter the field of vision of the Central Plains Dynasty in the early years of the Eastern Han Dynasty, during the Jianwu period, when Xianbei was still a small tribe, subordinate to the Xiongnu, and the boss, taking advantage of the fatigue of the Central Plains, went south to rob.

The Eastern Han Dynasty soon launched a counterattack, the fierce flames of the Xiongnu were suppressed, and Xianbei, the little brother, saw the decline of the boss, and began to play the quality of the grass on the wall, threw himself to the Central Plains, and began to attack the Huns.

The efforts paid off, and in the first year of Zhanghe, after that decisive victory over the Northern Xiongnu, the Xianbei people finally became the new overlords of the steppe. It not only received the territory and tribes of the Xiongnu, but also inherited the hostile relationship between the Xiongnu and the Han Empire. The foreign strategy of the Eastern Han Dynasty changed from the original fight against the Xiongnu to the joint Wuhuan and Xiongnu to fight Xianbei together.

Although Xianbei defeated the Xiongnu, it was unable to fully digest the results for a long time, and there were often internal battles, resulting in a completely incomparable strength with the Xiongnu or Donghu in their heyday. But after Emperor Guangwu, the strength of the Eastern Han Dynasty also deteriorated, and the threat posed by Xianbei to the Central Plains was not much smaller than that of the Xiongnu back then.

Especially in the more than 20 years of Emperor Huan's reign, the internal shortcomings of the Eastern Han Dynasty were fully revealed, but there were male lords rising on the grassland.

This is a figure similar to that of Temujin in later generations, starting as an abandoned baby, Tanshi Huai climbed up step by step, and finally became the overlord of the unification of the Xianbei tribes.

For the barbarians or those who envy the barbarians, his experience is quite an inspirational story. But for the Central Plains at that time, sandalwood only brought nightmares and disasters.

Since Li Ling surrendered to the Xiongnu in the Western Han Dynasty, the most tragic defeats of the Han Dynasty against the alien races in the grassland occurred in several invasion wars after the unification of Xianbei by Tanshihuai, especially the battle in the sixth year of Xiping.

At that time, Emperor Ling entered the border counties with Xianbei for many years, ordered Xia Yu, the captain of Wuhuan, and broke the Xianbei Zhonglang general Tian Yan and the Xiongnu Zhonglang general Zang Min each led more than 10,000 cavalry people. They went out of Gaoliu, Yunzhong, and Yanmen respectively, and attacked Xianbei in three ways.

"The Han army went out of the fortress for more than 2,000 miles, and the Xianbei leader Tan Shihuai ordered the eastern, central, and western three adults to lead the crowd to meet the battle, and the three battles were victorious, and the Han army was defeated. Xia Yu and other military baggage were lost. Seven or eight out of ten of the soldiers died, and the three of them each fled back with dozens of horses, and they were all exempted from the crime of defeating the army...... Alas, it was the old man who was sparse and prepared for the harm of Xianhumility, which led to this big defeat. ”

With a sad look on his face, Cai Yong sighed: "After that." Xianbei's army is more vigorous, and the military horses on the side of the road all take Xia Yu as a lesson from the past, trembling, and dare not meet the enemy. The court and the peace conference are also noisy. In the end, His Majesty adopted Duan Ying's proposal, wanted to crown him king, and then proposed a proposal for peace and affection. As a result, he flatly refused, causing the flames to burn even more. The situation is great and difficult to govern, if it weren't for the fact that Tanshi Huai did too much evil, provoked the disgust of heaven, and killed this bureaucracy, it would be a big disaster sooner or later. ”

Although Xia Yu and others were defeated, the war was in line with the consistent style of the Han Dynasty, and the Central Plains Dynasty in later generations who only wanted the frontier to have no major troubles and had to get by.

Usually a small fight and let you, make too much noise, just wait for the strong counterattack of the Han army, this is a tradition left over from the Han Wu era, and it has been pursued for hundreds of years.

However, if it weren't for Cai Yong talking about it, few people present really knew that behind that war, there was Cai Yong's promotion and the competition between all parties in the court.

Wang Yu listened to these old things in the court with great interest, but it was not where Qingzhou Wu paid attention, and the strength of the Xianbei people was the real focus.

"Although Xia Yu and others are not famous generals, they are also veteran generals who have led the army for many years, they have been on the battlefield for a long time, they are experienced, and they are all cavalry, well-equipped, but they are still defeated so badly, Hulu's combat power should not be underestimated."

"The key is their command and dispatch ability, according to Cai Zhonglang, between the chieftain and the tribes, there is not a strict relationship between the upper and lower levels, let alone the prohibition of orders, mobilizing hundreds of tribes and thousands of tribes, besieging the cavalry on all sides, such command and dispatch capabilities, it is really terrifying."

However, according to Cai Zhonglang, after the death of Tanshi Huai, didn't Xianbei fall into civil strife and attack each other? Tanshi Huai was followed by He Lian, who was shot from behind, and his nephew Kui took the top position, and then there was another Qian Man to fight with him...... At least for now, Xianbei shouldn't be much of a threat. ”

"I'm afraid that someone will make waves. The barbarians are not stupid, their own people have been fighting for so long, and they have not been able to get a result, at this time, if someone tells them that the Central Plains is already very weak, and someone leads the way, do you say that they will continue to kill each other, or will they go south together? ”

"Xu You, this guy really deserves to die, why didn't he catch him in the first place?"

"Xu Yu alone is not enough to be afraid, he is just a person with a mouth, the barbarians don't eat his set, the key is Youzhou. Liu Yu is highly respected by the local wealthy families, Xianbei and Wuhuan also praise his character and prestige, if he is harmful, the threat is much greater than Xu Yu. ”

"In this way, the lord sent troops not just to deal with Xianbei? If Xianbei doesn't come, will he wave his army to sweep Liu Yu, show off his martial arts, and take advantage of the situation to lay down the situation in Hebei? Well, this is a bit interesting, by now, Zhang Yan and General Gongsun should also understand the situation, whether it is military strategy and martial arts, or the leader of governance and development, they are beyond their reach, and if they continue to be stubborn, they can only be explained by personal ambition. ”

"Yes, the generals of the Gongsun Army are eager to check Gao Tang, except for a few people such as Shan Jing, the two families are one, there will not be much hindrance, this time to send troops, it is not a good time to pacify Hebei."

"In this case, we should act as soon as possible, the situation in Youzhou is tense day by day, and no one can say when the fight will start. If General Gongsun defeated Liu Yu first, and the Xianbei people did not come, wouldn't our army lose the reason to send troops? ”

"Everyone, everyone! Don't just talk about it, the army has not moved, the grain and grass go first, the 100,000 army goes north, how much it costs, we have easily accumulated two years of harvest, and if you don't do it, you will fill it all in, this is also what you want to see? ”

Zi Ni is reasonable, with the current situation, according to the policy of slowing down the plan formulated by the lord before, pacifying Hebei is a matter of three or five years, and it can be calmly discussed. The matter of Youzhou has not yet been decided, just send a general and send the elite of the first brigade to the north, why do you need to make such a big move? ”

The martial arts discussed one after another, and each insisted on its own words.

Wang Yu didn't know the reality of Xianbei people at the moment in advance, but he knew that Xianbei would become the main force of Wuhu Chaohua in a hundred years, so he always regarded it as a big trouble.

After learning about Xianbei's specific situation through Cai Yong, his worries deepened. During the Zhongping period, Zhang Chun, the minister of Zhongshan, rebelled and colluded with Xianbei and Wuhuan to enter the Kou, which turned the four states of Hebei upside down. At that time, the Xianbei that Zhang Chun colluded with was just a scattered tribe of Xianbei in the east.

The grassland, like the Central Plains, is also in troubled times, and the main forces of Xianbei are busy attacking and killing each other, and they have no time to go south. It is conceivable that if the Xianbei people suddenly reached an agreement and went south together, the threat would definitely be much greater than during the Zhongping period.

And Gongsun Zhan was already clumsy when he was crusading against Zhang Chun, and now Liu Yu's status is higher than Zhang Chun's, his power is greater than Zhang Chun's, and his reputation and appeal on the grassland are far from being comparable to the latter...... Can Gongsun Chan resist it?

If he can't resist it, and he is entangled with Cao Cao endlessly, the most serious consequence will be that the Wuhu Chaohua will be staged in advance, and it is unknown!

Therefore, after Lu Bu made his position clear, Wang Yu still decided that An Nei must first concentrate on pacifying Youzhou after the outside. The generals didn't have much objection to this, anyway, it was a war, but the enemy was different, but the ministers had a lot of concerns, and they preferred the strategy that Wang Yu had drawn up before.

After the Battle of Hebei, because the Qingzhou Army needed time to digest the results, the situation at that time was not enough for the Qingzhou Army to annex the two allies and solve Liu Yu, the opponent. Therefore, Wang Yu formulated a strategy of peaceful evolution, intending to spend a few years to solve the Hebei problem through development and bottom-up integration, and finally go to pacify Youzhou.

During this period, he would focus his main attack on Yanzhou, striking at and weakening the closest enemy, Cao Cao.

But people are not as good as heaven, the princes are not clay puppets, and they will not let Wang Yu do it.

First of all, Cao Cao saw the crisis, left most of Yanzhou and ran away, and sent Lu Bu, a hot potato, to Dongjun. At the same time, Yuan Shu was not willing to be lonely, stirred up the storm in Xuzhou, and finally the most critical, Tao Qian suddenly fell ill and died, so that Wang Yu had to put down the Yanzhou strategy and ride south to settle a bunch of troubles in Jianghuai.

In the campaign to pacify Xuzhou, Wang Yu has been unwilling to use the Taishan army to fight south, in fact, because he does not intend to give up the Yanzhou strategy, and is always ready to launch the Taishan and Yulin armies to carry out a comprehensive attack on Yanzhou.

Wang Yu's style has always been very direct, fighting quickly and quickly, taking the key points, and laying down a piece of territory, he can quickly settle down, and rarely engage in repeated tug-of-war somewhere.

The Yanzhou strategy follows this principle, so it is deeply respected by the ministers who govern the government.

Therefore, although Cai Yong's speech understood the harm of Xianbei, and also understood Wang Yu's mentality that he was more important externally than internally, except for Jia Xu, the ministers still did not support the Northern Expedition.

At that time, Emperor Wu launched a nationwide expedition to the north, and there were many large-scale battles with a scale of more than 100,000 people, but it still failed to completely solve the problem of the grassland barbarians. Although the current Qingzhou army is strong, can it be compared with the era of Emperor Wu? Although there are many famous generals in the army, how many people dare to claim to be better than Wei Huo Li Guang?

The northern expedition to Youzhou outweighs the losses.
