ps: Thank you to the maid butler for one monthly ticket, and thank you to the fire dragon baby brothers for two monthly tickets!

"Okay, soldiers, tonight's feast, when my three armies have all the food and grass, Lone will personally lead you, come to Liucheng, restore the land of my Han family, and avenge my Han family!"

Cao Cao waved his sleeves, and a common man sent the food that had just been sent into the barracks, good wine, good meat, everything, even those Wuhuan people got these things because of this, of course, Cao Cao was like this, just to appease them and let them do their best in the future.

After completing the things in the barracks, Cao Cao returned to the palace with the civil and military forces behind him, and on the banquet in it, Cao Cao could only reward the meritorious ministers with their own merits, so that the civil and military forces under his command were satisfied.

On the second day after this banquet, the soldiers and soldiers in the military camp were once again in high spirits and worked hard to cultivate, Cao Cao took Guo Jia and Sima Yi to the city wall of Lu Longsai.

"See your lord!"

The soldiers on the city wall of Lu Longsai saluted to Cao Cao, and after seeing Cao Cao nodding, he returned to his post again, and Cao Cao, who had a look of satisfaction on his face, took Guo Jia and Sima Yi to the front of the city wall, patted the female wall, pointed to the outside of the city wall and said: "Fengxiao, Zhongda, have you seen it." ”

When Guo Jia and Sima Yi heard this, after thinking for a while, they seemed to understand something, and stepped forward and said, "Go back to the king, the ministers have seen it." ”

Cao Cao turned his head, looked at the two of them and asked with a smile, "What do you see?" ”

"Northern Barbarians!"

Guo Jia and Sima Yi's words in unison made the two of them who didn't expect to be stunned for a moment, and then they looked at each other and smiled with a sense of pity.

"Yes, the northern barbarians, since the Zhou Dynasty, the northern barbarians, I think it is a big trouble for the Han people in my Central Plains, in the Spring and Autumn Period, if it weren't for the appearance of the Duke of Qi Huan, so that the princes of Jiuhe. As soon as the world is in the world, the Han people in the Central Plains may have perished in the hands of the barbarians in the Spring and Autumn Period, and after the Warring States Period, the Qin Dynasty unified the world. The Xiongnu attacked the Xiongnu in the north, causing the Xiongnu to dare not go south to herd horses, and when I was Emperor Wu, I defeated the Xiongnu and caused it to split. One of them is far away from the west, and the other is attached to my Han, however, from this time in the Spring and Autumn Period, they have been disturbed for hundreds of years, and the barbarians on the northern grasslands have eliminated a wave and there has been a wave, if my Han dynasty has been strong, until there is nothing to do, if it is weak. These barbarians living outside the Great Wall of the North are likely to bring great disaster. ”

Cao Cao's emotion made Guo Jia and Sima Yi agree in their hearts, both of them are not outstanding people in the world, and naturally understand that the northern barbarians will definitely be the biggest enemy of the Han people in the Central Plains, and the characteristics of the northern barbarians to eliminate wave after wave make every conquest of the Central Plains Dynasty almost useless.

"Your Majesty, thousands of years from now. We can't manage it, but in the past hundred years, we can manage it, and the king led the army to the north this time. The destruction of the Wuhuan army of 50,000 in a battle, and the destruction of the Wuhuan clan is close at hand, this alone is enough for the people on my northern border to enjoy a period of peace. ”

Guo Jia sighed and said these words in an almost helpless tone. It's not that he doesn't want to let the north settle from now on, but due to the limitations of the times, he didn't come up with any way at all.

From ancient times to the present, almost all the methods that can be used have been used by the Han dynasty in the Central Plains, whether it is the Qin Dynasty and the Great Northern Expedition of Emperor Wu, which is intended to eliminate the northern barbarians by force, resulting in the Northern Dading, or the later acceptance of the Xiongnu annexed, wanting to use the culture to integrate it and become the Han people, and finally lead the result, but there is no Xiongnu, and there are Xianbei and Wuhuan.

In Guo Jia's view, if you want to make the north settled, either the Central Plains Dynasty will continue to be strong, or the northern grasslands will disappear from now on, but no matter which one it is, it is all whimsical.

Sima Yi, who was beside Guo Jia, seemed to think of something, and said with a slight smile on his face: "Your Majesty, the ministers who used to manage the history books of the past dynasties can find one thing, the barbarians live with the water and grass, just because, compared with the Han people in the Central Plains, the northern barbarians are born by grazing, and the sheep, cattle and horses and other things are like the fields and acres and the Han people in the Central Plains for the northern barbarians, according to the minister's opinion, if you send people to lurk in the northern barbarians, and put poison in the water flow of the place where they settled, causing their animals and even people to die, so that"

I have to say that Sima Yi is ruthless enough, and his strategy is also very likely to be realized, at least the northern barbarians, in terms of appearance, are actually similar to the Han people, they are all black hair and black eyes, it is very easy for the Han people to ambush them, and therefore, the matter of poisoning has become very easy.

However, Cao Cao shook his head and did not adopt Sima Yi's strategy, not because Cao Cao was soft-hearted or sympathetic to the northern barbarians, but because Sima Yi's strategy was also a symptom rather than a cure.

Perhaps in this way, the northern barbarians will be afraid of this place for a certain period of time and move to other places, but there are thousands of nomads, and without these, there will be others, even Western nomads.

Don't think that this is impossible, the Xiongnu in East Asia had to migrate to the west because of the grasslands, and finally arrived in Europe after a long time, robbing the European grasslands, and at the same time leading the powerful and glorious Roman Empire to collapse under this great wave of ethnic migration because of the Northern Expedition of Emperor Wu of the Han Dynasty.

With such a lesson from the past, then the European nomads are likely to move to Asia more than a hundred years later, and at that time, Sima Yi's strategy will be abolished because of the different appearances, and at the same time, the dynasty of the Central Plains is likely to be unaware of how to deal with it because it has not been harassed by the nomads for a long time, and the final outcome will be even stronger than in the past.

Cao Cao, who looked at the sky in the distance, frowned tightly, eliminating Wuhuan, in Cao Cao's opinion, it is not a difficult thing at this time, after all, the system and culture of the Central Plains are already rich, and they are far stronger than the barbarians in the north, unless the Central Plains is in chaos and the vitality of the guide is greatly damaged, otherwise, as long as the Han people in the Central Plains want to, and turn their attention to the northern grasslands, it can be said that it is very easy to eliminate those nomads who may not even enter the slavery.

The northern barbarians, in the end, there is no way to completely eliminate them, and the way to cause the north to be determined.

Cao Cao had a secret thought in his heart, and kept thinking about the various history books he had read, the methods circulated on the Internet, and even the methods written in some novels he had read, all of which Cao Cao thought about one by one, in order to find a way to completely eliminate the border trouble in the north.
