Bingzhou is bounded by the Taiyuan line, including the northern part of Taiyuan County, the northern part of Xihe County, Yanmen County, Dai County, Yunzhong County and Wuyuan County, all the northern part of Bingzhou were occupied by the Zuoxian King's tribe of the Xiongnu, and a few Xianbei and Wuhuan people lived together during the period.

During the Eastern Han Dynasty, a large number of Han people also lived in the northern part of Bingzhou. The Huns and Han people lived together, and the Huns surrendered to the Han Dynasty. The court sent a captain to protect the Xiongnu to manage the nomadic peoples such as the Huns and Wuhuan. However, with the decline of the court at the end of the Han Dynasty, the Han Dynasty gradually lost control of the Huns. Liu Bao, the left wise king of the Huns, completely occupied the northern part of Bingzhou and began to expel the Han people, and resonated with the expelled Han people in Guannei and Hetao. A wave of refugees that lasted for decades, and the Yellow Turban Uprising was also triggered by the refugees.

At present, the northern part of Bingzhou is completely under Liu Bao's territory, but Taiyuan is still in the hands of Cao Cao. Since Liu Jing launched the battle against Wuhuan a few months ago, Cao Cao has gradually increased his troops in Taiyuan. Until Cao Pi successfully made a mission to Chang'an, Cao's army had increased its troops to 100,000 in Taiyuan, and even Cao Cao himself rushed to Taiyuan himself.

The Huns in the north have always been Cao Cao's confidant. His second son Cao Zhang fought against the Huns in Yanmen and Youzhou for many years. Several major wars broke out. Cao Cao even recruited Wuhuan people as cavalry and fought against the Huns. Because the Huns continued to cross the border and plunder civilians, the people in Bingzhou and Hebei suffered a lot.

Completely defeating the Huns and driving the Huns out of the northern border became Cao Cao's long-cherished wish for many years, but he was not strong enough to fight against the powerful Hun cavalry. This time, in order to move the capital to Guanzhong and eliminate the threat from the Huns to Guanzhong, Liu Jing launched a northern expedition and directly clashed with the Huns. This made Cao Cao see hope. He finally decided to join forces with Liu Jing to expel the Huns and restore China.

In Taiyuan City, Cao Cao was discussing the combat strategies against the Xiongnu in Bingzhou. In the first two months, Cao Cao also returned to Yedu. It was not until he heard the news that the Xiongnu Shanyu sent troops that he set off again to Taiyuan.

Cao Cao's temporary military headquarters was located in the Taiyuan Prefecture yamen. In the lobby, Cao Cao sat in the middle. Four strategists, Cheng Yu, Chen Qun, Liu Ye, Xin Pi, as well as generals Cao Zhang, Xu Huang, Zhang He, Xu Chu, Yu Jin, Cao Zhen and others sat down respectively. The marching Sima Tianyu introduced the current situation to everyone.

"According to the exact information, the Xiongnu Shanyu Huchuquan and the Right King Liu Qubei led a total of 100,000 cavalry to surround Gaonu City. This is the largest stronghold of the Han army north of Guanzhong. It is said that Zhang Ren led 5,000 people to garrison. The Xiongnu launched several attacks on Gaonu, all of which ended in failure. At present, the Xiongnu army is still in Gaonu, and has formed a situation of siege but not fighting against the city. It can be seen that this is a siege of the city and attacking aid. The Xiongnu hopes that the main force of the Han army will come to aid Gaonu."

"What's the situation here on Liu Bao?" Cao Cao asked.

"Reporting to Duke Wei, Liu Bao is relatively calm. Except for the 40,000 troops gathered in Dai County two months ago, there was no movement. However, Wei Chen received a piece of news that Liu Bao also went to the Xiongnu camp in Yinshan two months ago, so Wei Chen suspected that Liu Bao would not stand by and watch."

Cao Cao nodded and said to everyone: "Here, I need to clarify several principles to you first. First of all, we must seize this opportunity. We must take advantage of the Han-Hungary War to recover Bingzhou and relieve the troubles in the north, so we must send troops. Secondly, although this battle with the Huns was the will of the emperor, with me as the commander, and Liu Jing was only the deputy commander, but everyone should understand that Liu Jing and I were each sweeping the snow in front of the door. I cannot interfere with him, nor can he affect me, so our strength is limited, and we can only fight against the Bingzhou Huns at most."

Cao Cao said it was very reserved, and in fact he was reminding everyone that he and Liu Jing were still strong enemies. Although he temporarily joined forces to fight against the Huns, once the Huns retreated to the grassland, the war between Cao's army and the Han army would continue. Cao Cao did not want his advisers and generals to forget this, although he himself decided to marry his daughter to Liu Jing.

Cheng Yu's lips moved, and he wanted to speak but stopped. Cao Cao also saw that Cheng Yu had something to say, but at this moment, a guard rushed to the hall and reported loudly: "Report to the Prime Minister, General Cao Xiu has an emergency military report."

"Call him in!"

The guard hesitated and said, "General Cao Xiu said, the matter is relatively confidential."

Cao Cao nodded and said to everyone, "Let's stop here today, Zhongde stay."

Everyone stood up to say goodbye, Cheng Yu stayed, Cao Cao returned to the inner hall, Cheng Yu followed him, Cao Cao glanced at him and asked, "What did Zhongde want to say just now?"

"I want to remind Mr. Wei that everyone should sweep the snow in front of the door, and it seems to be a little too early."

“Why?”

Cheng Yu sighed and said, "Actually, I understand that Duke Wei wants to remind everyone not to get too close to the Han army, but the development of the situation is often not controlled by us. Once the Huns unite, our cooperation with the Han army is also indispensable. Therefore, I suggest that Duke Wei should take a broader view for the time being and not pay too much attention to temporary gains and losses."

Cao Cao suddenly woke up, and patted his forehead and said, "It was me who thought it was because of my simple thoughts, thanks to Zhongde's reminder!"

Seeing that Cao Cao readily accepted his suggestions, Cheng Yu was extremely happy and smiled and said, "In fact, Duke Wei's concerns are not unreasonable. Cooperation with the Han army too deeply will easily arouse the soldiers' recognition of the Han army. Once the war between the Cao army and the Han army is set in the future, an unfavorable situation will occur when the important generals of the Cao army surrender to the Han army. Therefore, the key is to grasp a certain degree. The cooperation with the Han army cannot be in depth or rejected. As long as you grasp this degree, I think Duke Wei will have no worries!"

Cao Cao nodded, "What Zhongde said is deeply loved by my heart!"

At this time, Cao Cao saw that there was a guard at the door that seemed to be reporting. He remembered Cao Xiu's incident and asked, "But Cao Xiu asks for a meeting?"

"Report to Duke Wei, that's right!"

"Let him in."

Cao Xiu was the deputy commander of the Tiger and Leopard Cavalry. This time he was appointed as the scout leader by Cao Cao. He was responsible for spying on the northern Bingzhou intelligence. Cao Cao knew that he had important military information and must be related to the Huns. After a moment, Cao Xiu quickly walked into the back hall, knelt down on one knee and saluted: "See Duke Wei!"

"What emergency military information is there to report to me?" Cao Cao's tone was very plain. He obviously didn't think there would be any emergency military information now.

"Report to Duke Wei, Hu Chuquan secretly sent an envoy."

This news made Cao Cao slightly stunned, and his eyes quickly turned to Cheng Yu. Cheng Yu nodded, "Duke Wei, this is within my expectations."

Cao Cao pondered for a moment and said to Cao Xiu: "You can report in a secret way. This is great. You can bring an envoy to the back hall to see me."

Cao Xiu bowed and left in a hurry. Cao Cao asked Cheng Yu again, "What does Zhongde think that Hu Chuquan is sending an envoy here at this time?"

Cheng Yu smiled slightly, "Hu Chuquan sent an envoy to come, at least confirming my speculation. The Huns did not separate Bingzhou and the inner city of Guan. If I was not wrong, Hu Chuquan hoped that Duke Wei would be able to hold his troops alone, and even hoped that Duke Wei would work with him to deal with Liu Jing."

Cao Cao couldn't help but sneer. At this time, the guards reported at the door: "Report to Duke Wei, the envoy of the Huns is here!"

"Send him in!"

After a moment, Cao Xiu led a thirty-five or six-year-old man in a thirty-five-year-old man, wearing a muddy hat and dark embroidered filament bubbles, which looked no different from Hu Shang on the market. He came in and took off his hat and revealed a shiny bald head. He bowed deeply, "Luan Tidaman, the right king of the Xiongnu, see Duke Wei!"

In name, the Huns still surrendered to the Han Dynasty. Shanyu Huchuquan also sent envoys to Yedu to symbolically pay tribute every year. At the same time, they met Prime Minister Cao Cao. Luan Tidaman had represented the Huns Chanyu on his mission to Yedu six times and was already very familiar with Cao Cao. Cao Cao nodded and smiled, "It turns out that it's an old friend, please sit down!"

"Thank you, Mr. Wei!"

Daman sat down, took out a sheepskin letter and presented it to Cao Cao with both hands, "This is a handwritten letter written by Shanyu to Duke Wei, please check it out."

A guard forwarded the letter to Cao Cao, but Cao Cao was not in a hurry to read it. He put it aside and asked, "Does King Rizhu come directly from Gao Nu, or from Dai County?"
