For all the dynasties in the Central Plains, the Northern Expedition nomadic peoples have always been a major concern.

Because of the different economic modes and survival methods, the rich Central Plains will always become the granary for those fierce and warlike nomadic peoples. Whenever the climate in the north changes and they are about to survive, they will invade the Central Plains, conquer cities, or rob people and property, and use the casualties of the people in the Central Plains to exchange for their own survival.

This characteristic has always been there, as strong as in the Qin and Han dynasties, and as weak as in the Zhao and Song dynasties, it became a humiliation of handing over Hebei to foreign tribes and tribute to other people's annual monies. Even if it is as powerful as the Tang Dynasty, when facing the rebellion of the Turkic rebellion in the north, it can only exchange a few years of peace at a small price.

Did the monarchs and ministers of all dynasties think of solving this problem once and for all?

Of course not. Whether it is Meng Tian in the Qin Dynasty, Huo in the Han Dynasty, including Li Jing and Xue Rengui in the Tang Dynasty, they all led their troops to fight the Northern Expedition. Relying on these famous generals and the elite troops of the dynasty, the Central Plains dynasty could always have a considerable advantage in the northern nomadic peoples, making them surrender and promising to not offend the border in the future. But, what?

Then as time goes by, as the wise and powerful generals die out one by one, and as the dynasty begins to decline, the jackals and robbers on the grassland will make a comeback and invade the Central Plains again. They regard the so-called relationship between the king and the minister and the so-called promises as bullshit. In their eyes, the Central Plains is their pasture and pasture, and they must rob and kill.

The root of all this is still the asymmetry between the Central Plains and the grasslands, because there is nothing worthy of the vast grasslands that the Central Plains dynasty covet, even including their small population. Therefore, every time the Central Plains dynasty is strong, although the northern expedition is in power, it cannot really solve the problem. Even in this dynasty, two generations of Taizu and Taizong have made more than ten northern expeditions, and only a decades of peace in the northern border.

Sun Bi has been paying attention to these things for a long time.

After a long period of thinking, he finally came to the conclusion that the threat of the nomadic tribes in the north was in the end, not people from the Central Plains, but people from the grassland.

They have to reproduce and survive, so they will invade the Central Plains when they cannot survive. What’s more important is that when the strength of both sides changes, their desires will continue to increase, from being just to survive with enough food, to later plunder more population slaves, plunder more wealth, even land and cities!

Since the root of the person is in the human world, kill all the people, and it will be done once and for all!

As long as the tribes on the grassland whose strength is constantly expanding are uprooted and not given them a soil for continued development and survival, the threat from the north to the Central Plains will no longer exist. At the moment, it is to completely eradicate the Guirong tribes!

He thought so and did the same. From leading troops to the northern expedition and deep into the grassland, the Vietnamese army had already launched an operation to clean up all the Guirong tribes. As long as the Guirong people on their route were on their way, no matter which group or how many people, they were dead, and even all the property of their tribe was plundered.

It was precisely because of such a powerful move that the later Gui Rong tribes were truly panicked, and then they kept retreating north, and under the order of Tielzhen, they launched a counterattack near the current Juerong Mountain.

But the final result was that Gui Rong's entire army was defeated... But in this way, a new problem occurred. On the vast grassland, when these nomadic tribes really wanted to escape and hide, could the unfamiliar Vietnamese army find them and wipe them out one by one?

This is also the biggest problem faced by the Northern Expedition army in all dynasties. None of the famous generals in history are ruthless people. When they can really kill the enemy, how could they let them go easily? It was only later that the battle went on and all the troops in the grassland fled far away, which made the new battle impossible. In addition, the logistics support could not keep up, so they had to retreat.

But this time, Sun Bi has how to deal with this problem that has been around for thousands of years?

...

Tie Lezhen and other generals led the defeated army to flee in a panic, and finally got rid of the pursuit of the Vietnamese cavalry. After all, when it comes to horse riding, the Central Plains cavalry was still quite different from them. However, their losses were particularly serious. Now there are less than a thousand people who are following him, and they are all injured and in a mess.

"Khan, what should we do next?" a subordinate asked with a look of frustration and despair.

The defeat in this battle hit these soldiers with a severe blow, much more severe than the previous defeat in the Central Plains. Everyone has no longer had the intention to fight the terrible Vietnamese army.

Tie Lezhen turned his head to look at the subordinates around him, his face full of bitterness. But then, he cheered up again: "We may not have a chance, but our descendants can still reappear the glory of the grassland... So what we have to do now is to take them and hide first. Let's go and find our tribe members..."

Although this was not very encouraging, everyone agreed and followed closely, running in one direction. Along the way, they kept paying attention to the surroundings, fearing that when will the Vietnamese army chase after him again.

However, this time, they did not encounter such a thing again. They successfully arrived in front of a semi-freezing river, and then wandered up the river water, and soon saw the valley ahead - which was the hiding place of their tribes now.

After being slaughtered by the Vietnamese army regardless of age, the grassland tribes had long become frightened birds and all hid northward. In order to survive, the tribes had to gather together to keep warm. At this time, there were more than a dozen tribes, tens of thousands of elderly, weak, women and children, which can be said to be the last hope on the grassland.

Since they were defeated in this battle, Tie Lezhen and the others could only accept the facts. Next, they would continue to go north with their own tribes, try to stay away from the terrible Vietnamese army, rest and recuperate, spend decades of restoring their vitality, and then think about killing them back.

With such a plan in his mind, everyone quickly rode forward, and in a blink of an eye, he had arrived at the entrance of the valley. Then, Tie Lezhen, who was walking in the front, changed his expression: "No... Why is the valley so quiet?"

Others also reacted and showed vigilance. Yes, it was afternoon now, and the sun was shining, and both people and livestock should be active outside. And seeing so many people approaching, it was long time since someone came out to greet him, but now it was quiet, like no one.

Bo Chishu, who was beside him, exclaimed after taking a few breaths: "There is a bloody smell... something happened..."

With this exclamation, the soldiers who were already worried about their family quickly urged the horse to rush in, and then led more people to rush into the valley regardless of concern. Even Tie Lezhen followed in after hesitating for a while.

Then, in front of them, a scene that made everyone's eyes burst out--

On the large grassland that should have been peaceful and warm, blood was covered with corpses all over the valley. Most of the tents that were the homes of these herdsmen had fallen down, and half of them had never seen them.

Tens of thousands of herdsmen, women and children all over the valley have become corpses, and no chickens and dogs are left behind!

Just as the Guirong people did when they invaded the Central Plains, when they broke through a city and left, they would only leave behind dead bodies and messes in the city. Now, this scene was completely unchanged, without any discount.

At this moment, all the Gui Rong Knights, including those leaders who have experienced many battles, Tie Lezhen, who thought he had experienced many storms, were completely stunned by the bloody scene in front of him.

They really didn't expect that when they came back, they would see such a miserable scene. How could this be possible?

When did the Han people in the Central Plains become so cruel and ruthless that they would not even let go of women, children and elderly people who had no ability to resist? Didn’t they always talk about the way of benevolence and forgiveness, and wouldn’t they always leave a bottom line, so that the entire grassland can be revived again and again?

And a more critical question is how did they find this place?

In order to preserve the future of the tribe, the Guirong tribes spent a lot of time to find such a remote and safe place. It was precisely because they determined that this place was safe enough that they dared to bring all the troops that could fight out just to defeat the enemy in one battle.

But now, the facts tell them that their calculations were all wrong, and they killed all their tribe members.

The huge impact made everyone there. Tie Lezhen's eyes flushed and his body trembled. He wanted to shout revenge, but he knew that this was impossible. They had already lost, and now they might not even have any future. I am afraid there is no hope of revenge...

Just as he had such thoughts in despair, the sound of whimpering horns sounded from outside the valley, followed by the huge movement of the team and the unique shouts of killing by the Han army. The murderers who had slaughtered the entire grassland tribe did not leave, but actually hid on the side.

After seeing that he came back, he decisively rushed over and cut off the road out of the valley. Tens of thousands of troops rushed over like the wind.

More than a thousand defeated soldiers, even though they were filled with anger and unwillingness, when facing the fierce attacks of dozens of times the enemy and when all the backs were cut off, they no longer had the possibility of even in case.

Half an hour later, all the ghosts and Rong people in the valley were killed, and Tie Lezhen was cut off by Yue Lin himself.

Yes, this time, the one who lies outside and killed all the Guirong people in the valley before was the Jizhou army led by Yue Lin. The reason why he appeared here and found the Hidden place of the Guirong tribe was due to the previous strategy given by Sun Bi, a wonderful strategy to lure the snake out of the hole and then hit the snake's hole.
