Gao Shun ignored the external disturbances and made every effort to prepare for the recovery of Wuyuan County, but at this time, an unexpected thing happened inside Xianbei, and the news came, which made Gao Shun's expression lift.

In the past few years, King Xianbei and Lian attached great importance to Gao Shun, the general of the expedition to the north, and the border army under his jurisdiction, and planted many secret agents in the border counties of Dahan to pay close attention to the movements of Gao Shun and the border army.

In July, the spy found out that the champion Hou was not in Taoyuan Fort, but was patrolling around the jurisdiction, and it was estimated that he would not return in a short time; The Han border army was very quiet, and there was no sign of troop build-up.

When the news came back and it was confirmed, King Helian was overjoyed and decided to take the opportunity to go south to plunder.

In recent years, the tribe of Helian and several nephews has occupied the most fertile area of water and grass, and it has developed very rapidly; The population and livestock of the tribe continued to increase, and there were no large-scale wars, and the number of warriors increased year by year, so that the ambition of the king of Helian swelled; He can't deal with the Han border army now, but he can take the opportunity to make moves against other tribes and other races to strengthen his own strength.

And the king of Helian is in urgent need of looting materials for him to squander. He was mediocre in ability, extravagant, and unfair in rewards and punishments, and if it weren't for the rapid development of the tribe in recent years to cover up internal contradictions, several of his nephews would have broken with him a long time ago; And with the external pressure of the Han border army, the situation is grim, and they cannot be allowed to engage in internal strife.

Beidi County was plundered and threatened by the Qiang and Xiongnu, and the officials such as Taishou had long since withdrawn to the interior, and now the Hu and Han people lived there, and various forces were intertwined, each doing its own thing, attacking each other, and it was chaotic.

King Helian did not dare to plunder the Great Han, but he was full of confidence in plundering this chaotic place.

King Helian summoned several of his nephews to come and discuss; Budugen strongly opposed, the Han officials have a lot of conspiracies and tricks, and they must be dealt with carefully, if they are out of the nest, the interior is empty, it is easy to be invaded by the Han border army, and they have lost their foundation, how can they survive after that? And now is the season of harvesting forage, if the gathering of troops, affecting the forage harvest, will cause many livestock to starve to death in winter, seriously weaken the strength of the tribe, affect the life of the people.

The leader was plundered by Lu Bu last year, and suffered heavy losses, and strongly supported He Lian's opinion, hoping to replenish his tribe by plundering the Northland County, of course, he had a more ambitious plan, and he had been waiting for this day for a long time.

Fu Luohan was unassertive and echoed the Chief's opinion.

King Helian was stubborn and had made up his mind, so he ordered Budugen to stay behind and lead the army to guard against the Han border army and protect the safety of the tribe. He believed that if he didn't loot now, when Gao Shun returned, or when the Han border army gathered, he would not have the opportunity to go out to plunder, and looting a large amount of wealth to replenish the tribe could increase the trust of the people in him and strengthen his rule.

Budugen was lonely, so he had no choice but to take this order and lead the army to be stationed in Jiuyuan County.

In mid-August, King Helian gathered an army of 40,000 and marched west along the Yellow River, then turned south and headed south along the west bank of the Yellow River.

The army continued southward into the alluvial plain of the Yellow River; The Yellow River runs through it, and irrigation is convenient, and it is not only a fertile pasture, but also a fertile and fertile field, which is called "plugging the south of the Yangtze River" in later generations.

The Han Dynasty had a large number of immigrants to this place, and then also brought advanced farming technology in the Central Plains, in order to expand the cultivated land, and opened a large number of Han canals, which became a very good grain production area.

After the evacuation of the Beidi County Government, the Han people who stayed in the country relied on the powerful forces to form several forces, either building forts and living there, or occupying the county seat and defending it, and cultivating the surrounding land; The Qiang, Xiongnu, etc., grazed their cattle far from the castle or county seat.

They attack each other, and neither can easily destroy the other, otherwise they will suffer heavy losses, and it is easy for others to take advantage of them, so they finally form a relatively stable form.

King Helian took the advice of the chief, bypassed the castle of the Han people, and only plundered the towns of Qianghu outside the city; This was to take advantage of the charge of their cavalry, which paid very little but gained a lot of money, plundering not only a large number of people, but also a large number of livestock and food.

The Han people are good at defending the city, and there are obstacles such as antlers, trapping pits, and tripping ropes outside the castle, and there are ditches under the city; The Xianbei people will weigh the pros and cons, and if it is not necessary, they will not choose to storm the Han city, otherwise they will pay heavy losses.

Beidi County is located on the border, abandoned by the government, the Han people here, life is also very poor and hard, they spend a lot of money to conquer the castle, the harvest will not be very large, not as well as plundering the more rudimentary defense of the Qianghu, and more able to give full play to the advantages of cavalry, captured population and livestock are more important to them.

If the Xianbei people plundered the Han people, they could only become slaves; If you plunder the nomadic tribes such as Qianghu and adopt the rules of the steppe tribes, kill the old and weak and the young and strong who are more than the height of the wheel, and the rest of the people can be divided into subordinates and organized as tribesmen; If they surrendered voluntarily, their young and strong people could be incorporated into the army, which immediately strengthened their strength.

The life of the steppe tribes is hard, the population reproduction rate is very slow, the population is their very precious resource, and women are very important trophies, if they can not be killed, they will not be killed.

King Helian gathered an army of 40,000 troops, and it was difficult for any tribe in Beidi County to fight alone, and in the early stage, it was devastating all the way, and it was extremely smooth, sweeping hundreds of miles, without encountering any decent resistance, but the results were extraordinarily rich, which made all the Xianbei people overjoyed and their ambitions swelled.

In order to speed up the efficiency of the raid and quickly expand the results of the battle, King Helian, who was carried away by the victory, ordered the troops to be divided into three routes, he personally led 20,000 cavalry in the center, and his two nephews each led 10,000 troops to the left and right sides, and pushed to the south.

He Lian's order was in the hands of the leader, he had been planning for a long time, and he was worried that he had no excuse to act alone, but he didn't expect He Lian to take the initiative to give this order, it was really destiny.

Last year, in order to resist the attack of the Han border army, he gathered the tribal cavalry to the east, resulting in the emptiness of the tribe, and was plundered by Lu Bu, which made him suffer heavy losses.

He Lian is cowardly and incompetent, if it weren't for the assistance of their three brothers, how could they be today? In addition to Helian, if the tribe is under his leadership, it will definitely achieve faster development, otherwise, the tribe will be wiped out by the Han border army sooner or later, which is also for the sake of Xianbei's future.

According to the idea of the leader, after removing Helian, Helian's son is still young and needs someone to assist, and he is the oldest and the most ideal candidate, he can be in charge of his current subordinates and Helian's subordinates, and when he is strong, he can suppress Fu Luohan and Budugen to accept his command.

Integrating the current strength of several tribes, he can completely unify the western Xianbei, not only increase the population, livestock and army, but also increase the occupation line of thousands of miles, making it easier to compete with the Han Dynasty, otherwise, in a few years, the Han border army will recover their current pastures, and they will have nowhere to go.

Gao Shun adopted a step-by-step strategy, which not only made Bu Dugen feel a lot of pressure, but even the leader felt an existential crisis.

This expedition to plunder the Northland County is the best opportunity for the leader to get rid of the king of Helian, he has endured it for a long time, how can he miss it?

However, this time he divided the troops, he was ambitious, and he brewed a more ambitious and huge plan in his heart, not only to get rid of King Helian.
