Thinking of this, Liu Bei began to complain that he didn't grit his teeth and insist at that time, and completely broke down the central Xianbei.

At that time, if I had insisted on it and destroyed the central Xianbei together, there would not be so much trouble now......

Liu Bei rubbed his temples with some annoyance.

"Could it be that the resumption of our state operation has stimulated them?"

Liu Hui said in a low voice: "To the north of Bingzhou, it is the range of activities of the Xianbei people, maybe they even regard a part of Bingzhou as their territory, as soon as we act, they will know." ”

"In this way, we are not thinking about it."

Liu Bei said slowly: "How many people and soldiers and horses are there in Xianbei in central China? ”

"It is roughly estimated that the scale of the population is 1780,000, and there are more than 30,000 victories, less than 40,000."

Liu Hui said: "After the blow of the previous Northern Expedition, now their population and the number of soldiers and horses should have decreased, and they will not be as many as in the past, and the current Xianbei in the west and Xianbei in the east have been conquered by our army, and they have suffered heavy losses, and only Xianbei in the central part is left alone, which is not difficult to deal with." ”

"So...... Are they really gathering men at this time to take the initiative to attack me? ”

Liu Bei looked at Liu Hui suspiciously: "Our army has fought many battles before, and it should have been frightened a long time ago, but now that I heard that our army is going north, I dare to take the initiative to attack south?" Do they think they have lived too long and take the initiative to die? I can't figure it out. ”

When Liu Bei said this, Liu Hui also felt a little depressed, and couldn't think of the essentials.

"There are indeed a lot of things in this world that can't be figured out, so ...... Shall I go again? ”

"Well, you go and see if they really want to attack south."

Liu Bei nodded, so Liu Hui left quickly.

After Liu Hui left, Liu Bei felt that no matter how much he thought about it under normal circumstances, he would not come up with the possibility that Xianbei in the central part of the country would dare to go south directly, but there were too many things that seemed impossible in the world, so he still had to prepare for both.

So he ordered Xiahou Yuan to be the general of the leopard cavalry, let Xiahou Yuan make war preparations, and if the remnants of Xianbei in the central part really dare to go south, then let Xiahou Yuan lead troops north to support Guan Yu and lead the move - and then the northern expedition completely wiped out the central Xianbei.

Although the cost will be relatively large, and the logistical pressure will increase, the other party has made a move, and he must give them a head-on blow.

And this money ...... It's not that you can't afford it, it's just that it wasn't in the budget at the beginning, and now if you really want to pay for the Northern Expedition, the treasury will run a little, it's really not good, plus Shaofu, you can definitely afford to fight this war, and the seizures after the war must be quite rich.

The previous Battle of Youzhou and the Northern Expedition brought Liu Bei a huge amount of wealth, selling livestock and prisoners of war to Jizhou, Qingzhou and even Yanzhou, and other places, all of which made a lot of money and food, and the development and construction of Youzhou was also supported thanks to this huge income.

The local wealthy families in Jizhou, Qingzhou and Yanzhou were very interested in the cattle and sheep on the grassland and were willing to pay for them, and they were also very interested in the Xianbei prisoners of war, and spent a lot of money to buy a number of prisoners of war from the imperial court to serve as slaves.

Counting the official slaves needed for the local construction of Youzhou, as well as the high-quality grassland humans who helped the imperial court build pastures, the huge prisoner of war population obtained in this battle basically had a place to go, and it was quickly digested by the Han Empire.

After that, the imperial court calculated an account, calculated the losses and expenses of the entire war, as well as the benefits obtained from the war, and found that the business was quite profitable.

By selling prisoners of war and livestock, as well as accepting official slaves for use, the imperial court not only did not lose money, but even leveled the construction costs of Youzhou and Bingzhou, and in the end, made a small amount of money.

It can be said that the Battle of Youzhou and the Battle of the Northern Expedition not only did not lose money, but also made money, and this interesting fact made Liu Bei win a lot of prestige in the imperial court.

From this point of view, if the war against Xianbei in the central part of the country is started again, it is just another "purchase" to the north, and the resistance in the court will be very small, or even basically none.

From other perspectives, Liu Bei did not rule out launching another complete attack on Xianbei in central China.

The Xianbei ethnic group profoundly influenced the trend of Chinese history for hundreds of years, and it was not until the Sui and Tang dynasties that it gradually disappeared and was assimilated by many other ethnic groups.

At the moment, Liu Bei has wiped out the main forces of Xianbei in the west and Xianbei in the east through two Northern Expeditions, and it is difficult for the remaining Xianbei people to make any waves.

I just don't know if after the Xianbei people leave, who will rise up in a place beyond his control, and then gradually ...... south

However, according to his prediction, if he really wiped out all the Xianbei people and swept the northern grasslands within a period of time, then there would not be a single nomadic group with a substantial threat on the grasslands for hundreds of years.

The reason is simple, the Xiaoice period is coming.

At this stage, the ecological environment of the northern grassland will become harsh, and the relatively warm time is no longer suitable for the birth and development of a group, and the natural climate and resources cannot support more population.

Without a buffer during the warm period, even if there were sporadic migrations of nomadic tribes, it would not be possible to grow the population much.

Unless they move south towards warmer regions, the harsh natural environment will not be able to support the overpopulation, and the power of nature will automatically help humans control the size of the population.

And without the explosive growth of the grassland population during the warm period, it is naturally impossible to push them to further expand their living space to the south in order to survive during the Xiaoice period, not to mention the hundreds of thousands of grassland cavalry roaring south.

There are simply not so many people who can live on the grassland, nature does not allow it.

In other words, even if they can't be completely wiped out, as long as the Xianbei forces in the northern grasslands are wiped out at this stage, then a threatening nomadic armed group will not be able to grow on the grasslands for hundreds of years.

It was not until the warm period of the Sui and Tang dynasties that a new grassland tribe might emerge to pose a threat to the Central Plains Dynasty again.

This is a great historical opportunity.

Thinking about it this way, Liu Bei felt that it would be necessary to send troops to sweep the grasslands.

As long as this wave insists on winning, it can usher in a golden development period of several hundred years, which is rare in the entire history.

And what happened after that proved that there are many unpredictable things that can happen in the world, but there are still many more predictable things that can happen.

For example, Liu Bei's judgment of Central Xianbei actually did not make any mistakes - Central Xianbei fled, not from the south.

They really didn't make a big move, they just moistened it.

Hearing that Liu Bei launched a military operation against Bingzhou, the most powerful adult in the central Xianbei was frightened, and felt that this was the precursor of Liu Bei's war against the central Xianbei.

He thought that Xianbei in the middle of the country had been licking his wounds honestly these days, and he hadn't done anything, and he didn't dare to retaliate against him because of Liu Bei's attack before, where did he provoke Liu Bei?

But whether it should be said or not, what the strong do to the weak does not need reasons and excuses, nor does it require anyone's consent, as long as the strong are willing, anything can be done.

Budu thought about it, and felt that he couldn't beat Liu Bei no matter what, for fear of suffering the same thing as Su Li, Micah and others, so he only had the last choice.

I can't beat it, can't I dodge it?

Other powerful adults in Central Xianbei were also afraid of Liu Bei's strong force, and they didn't dare to confront Liu Bei, and they didn't want to die, so they could only keep up with the pace.

So by the time Liu Hui found out the specific news, they had already begun to migrate westward.

More than 100,000 people moved westward with a large number of livestock and property such as cattle, sheep and horses, and a large group of people wanted to leave where Liu Bei's troops could reach and go to the farther west to survive.

When Liu Bei heard the news, he was a little happy and a little depressed.

I am glad that my reputation has finally made the Xianbei people retreat without a fight.

It's frustrating that they are running now, but they can't chase after them, and I don't know where they will run in the future.

If we do not destroy them now, it will be a scourge after all, and this scourge must not be left to future generations.

Therefore, Liu Bei could only continue to issue long-term orders to Liu Hui, asking him to send people to follow and master the escape route and final settlement of Budu and his subordinates, and when his side was free, he would launch another Northern Expedition to wipe out the military armed groups on the grassland in one fell swoop.

Even if you run to the ends of the earth, I will catch up with you and kill them all.

Liu Bei's fierce and greedy eyes were projected in the northwest direction.

At present, the military operations of the Han army in Bingzhou are still continuing.

In mid-to-late March, the army of Zhao and Yu Fuluo fought against a large Xianbei tribe in the Hetao Plain area of Shuofang County, and completely wiped out this large tribe of 20,000 or 30,000 people, and achieved great results.

On the sixth day of the fourth month, Guan Yu's troops defeated a group of more than 5,000 Wuhuan soldiers and their tribes in Yuanyang County, Yunzhong County, and won a great victory.

On the eighth day of the first month of April, he recruited the commanders to defeat the Xianbei and the Xiongnu in Xi'an County, Wuyuan County, beheaded more than 1,000 and captured more than 10,000.

On 15 April, the lead arrived at Jiuyuan County, Wuyuan County, and on the same day, the vanguard of Guan Yu's department arrived in Xianyang County, Yunzhong County, and the two armies basically completed the task of merging the prefectures.

With full of gains, they conveyed the message of victory to Liu Bei, so that Liu Bei, who was far away in Luoyang, knew about their brilliant victory.

The state was merged, and it was recovered.

Liu Bei established a topographical sand table in Luoyang, constantly updated the direction and results of Guan Yu and his troops in real time, and carried out remote military situation understanding according to the battle report.

When he learned of the latest progress of Guan Yu and the two armies on 23 April, he knew that the battle had been successful.
