Liu Teng's death caused great chaos in Jiuyuan City, and after Liu Teng's cronies and subordinates found out that Liu Teng had been killed, they were extremely angry and fought to avenge Liu Teng.

But since Liu Meng, Liu Bao, and Liu Jiao had already conspired against Liu Teng, they must have made a detailed plan, and after killing Liu Teng, the three Xiongnu in the city and the men and horses in Tuntian outside the city moved at the same time, attacking inside and outside, and launched the most fierce attack on the northern Xiongnu.

Almost all the military camps and strongholds of the northern Xiongnu in Jiuyuan City were besieged by the three Xiongnu.

The northern Xiongnu were in a hurry, completely passive, with heavy casualties, coupled with Liu Teng's death, the northern Xiongnu lacked the backbone, the dragons were leaderless, and they were in a mess, under the siege of the three Xiongnu, except for a few people who were loyal to Liu Teng who would rather die than die in battle, most of the northern Xiongnu chose to surrender.

Liu Meng and Liu Bao did not kill all the northern Huns who surrendered, after all, they still had to count on the northern Huns to provide them with logistical support.

Although the situation was quickly contained, the turmoil caused by it was difficult to calm down in Jiuyuan City for a long time.

Cao Liang got the news from Jiuyuan almost that night, in order to spy on the movements of the Huns in Jiuyuan City, the Wei army sent more than a group of scouts, and the bloody scene in Jiuyuan City naturally couldn't hide these scouts.

The usual news can be delivered slowly, even if it is a day or two apart, it doesn't matter, but such a big change has happened in Jiuyuan, this news can not be delayed at all, and the secret agents lurking outside the city of Jiuyuan immediately sent fast horses to Jinyang to pass this major disappearance back.

When the news was delivered to Luoyang, it was the time of the third watch of the Tianjiao, and at this time, Cao Liang did not rest, but worked with candles to deal with many affairs of the state capital.

Last year, due to the war, ninety percent of the fields in the entire state were deserted, and there was no grain in the treasury, and more than 300,000 soldiers and civilians in the state all counted on the grain and grass distributed by the imperial court.

If the people of Bingzhou want to survive, they must be self-reliant, open up wasteland and cultivate land, only in this way can there be hope.

Cao Liang is ready to do a big job in Bingzhou, so his affairs in Bingzhou are not only about fighting a war, but the most important thing is to solve people's livelihood problems, only in this way can Cao Liang have a chance to gain a firm foothold in Bingzhou.

To solve the problem of people's livelihood, the first thing is to solve the problem of spring plowing and preparation, and only by planting seeds in the ground can there be a chance to harvest in autumn.

However, due to the war, the population of Bingzhou has decreased considerably, and because the people who have returned to their hometowns only account for about 50 percent of the original population, there is a shortage of labor, and a large number of fields have been abandoned.

In order to solve the problem of abandonment of fields, Cao Liang set out Tuntian, and those Xiongnu civilians who were captured in Zishi, Daling, and Qi counties became the main force of Tuntian.

Cao Liang knew that he was under his command, but there was a master of Tuntian, that was Deng Ai, when he had Runan, he held the official position of Tuntian, and he had a set of methods for managing Tuntian.

So Cao Liang temporarily transferred Deng Ai to supervise the affairs of Tuntian, and it happened that there was no war during this time, and Deng Ai could completely withdraw from it.

Deng Ai really lived up to Cao Liang's high expectations, managed the tuntian, mastered it with ease, arranged it in an orderly manner, built water conservancy, excavated channels, and in less than half a month, the entire tuntian camp took on a new look, and farming and production were also carried out in an orderly manner.

In order to confuse the Huns in Jiuyuan, Cao Liang deliberately arranged for a part of the Wei army to enter the Tuntian camp to assist in production, so that the Huns in Jiuyuan could believe the truth and regard the Wei army as the main force in Tuntian.

In fact, even if these Wei troops entered the Tuntian camp, they were not engaged in agricultural production, but did not unload their armor and horses, and were always preparing for the march.

When the news of the war in Jiuyuan reached Jinyang, Cao Liang sighed sincerely: "Mr. is really like a god!" ”

Everything was as Huan Fan expected, after the Wei army temporarily abandoned the attack on Jiuyuan, the Huns really had civil strife, and the originally monolithic Xiongnu defense line finally cracked.

Cao Liang waited for half a year, waiting for such an opportunity, if the Huns were united, Cao Liang was really not easy to deal with, but at this time there was such a major change among the Huns, it was definitely a godsend, so Cao Liang ordered overnight that all the Pingbei Army gathered and prepared to go out.

Originally, it took a lot of time for an army to go on an expedition, raising food and grass, preparing ordnance, tents, utensils, and other things, but just making these preparations before the expedition had to be delayed for several days.

The Pingbei army seemed to have been prepared, and after Cao Liang's order was issued, it only took them half a day to complete the assembly.

In fact, when spring came, the Pingbei Army had already made all the preparations before the expedition, even if many troops were transferred to various tuntian locations, it did not affect the preparation of the Pingbei Army at all, all they needed was an order to go out, as long as this order was issued, the entire Pingbei Army could set off at any time.

Deng Ai also returned to the Yueqi camp as soon as possible, and his official position in Tuntian was originally a part-time job, and his stay did not affect the affairs of Tuntian at all.

And Cao Liang is also quickly arranging the affairs of the Assassin Historian of the Prefecture, he has been in office for half a year, has greatly changed the efficiency of the Assassin of the Prefecture, he is very good at cultivating and discovering the ability of subordinate officials, so that they can become good at standing alone.

It is precisely for this reason that Cao Liang successively removed many state government officials who were superficial and had no real talents, and exceptionally promoted some officials with outstanding ability to work hard from below, so as to enrich the bureaucratic team of the state government, so as to ensure that when he could not see things, the state assassin history office could operate at the same speed and effectively.

In the northern expedition to the Xiongnu, Cao Liang will temporarily stop the post of assassinating the state and go all out to be the general of Pingbei, which is also the first time that Cao Liang has performed his duties as a general of Pingbei in the past six months.

With a military order, the Pingbei army left Jinyang City in a majestic manner and looked north.
