Lü Bu led a large army into Bingzhou, but did not encounter any interception along the way.

They seized the city one after another, and most of the annexed states soon fell into the hands of Cao's army.

The progress was too smooth, and Cao Shuo felt that something was not right.

During the march, he asked Guo Jia: "Fengxiao, why did you say that Gao Gan didn't lead the army to meet the battle?" ”

"Gongzi is pro-enlisted, and Gao Gan does not dare to come even if he has a hundred guts." Guo Jia said: "The scout is not a return, saying that he can't get out of the pot at this time, I'm afraid he wants to resist Gongzi in the pot pass, so that Gongzi will eventually return in vain." ”

"Kettle off." Cao Shuo frowned.

If Gao Gan defends a city, Cao Shuo doesn't feel that there is anything difficult to do.

But he chose to guard the kettle.

Huguan is close to the outside of the Saiwai, once the high-ranking soldiers are defeated and flee into the territory of the Southern Xiongnu, it is not so easy to find him.

And at this time the pot is off.

Gao Gan stood at the pass, looking into the distance.

He said to the two generals standing beside him, "Invite Zhong Changtong, I have something to ask him." ”

One of the generals, answered, and ordered a soldier to go and ask for the commander.

After a while, the soldier arrived with a soldier in his forties.

This person is the Zhong Changtong that the senior cadres are looking for.

When he arrived at Gao Gan's side, Zhong Changtong saluted and asked, "The general is looking for me?" ”

"Sir has been with me for many years." Gao Gan said: "Today is the time to use Mr.'s talents, I don't know what Mr. thinks I should do to refuse to defend the Huguan Pass and force Cao Zirong to retreat?" ”

"At the beginning, I came to persuade the general to come to the aid of the third son of the Yuan family, but the general refused." Zhong Changtong said: "When I rebelled against the Cao family, I said that the Cao family was powerful, and the general did not have many soldiers and horses, and he was not the opponent of the Cao army at all......

"It's useless to talk about that." Gao Gan said: "I want to know how to repel Cao Zirong? ”

"If the general is Cao Zirong, what will he do when he comes to Huguan?" Zhong Changtong asked.

"Assault." Gao Gan said: "Behind Huguan is outside the plug, our army will not be short of food when stationed here, Cao Zirong should understand very well, even if he besieges here for ten years, I am not afraid." ”

"But the general can only be in Huguan for ten years." Zhong Changtong said: "If the general wants to break through the dilemma, there is another way. It's just that I don't know how much it counts. ”

Zhong Changtong said that there was another way, Gao Gan's eyes lit up, and he hurriedly asked him: "Dare to ask sir, what is the method?" ”

"Previously, Cao Zirong had defeated the Southern Xiongnu." Zhong Changtong said: "Although the Southern Xiongnu surrendered to him, they must not be convinced in their hearts. The general can go to the Southern Xiongnu and ask, are they willing to send troops to help? ”

"I have a good relationship with the Southern Xiongnu Dadan Yu Chuquan." Gao Gan said: "It's a pity that Hu Chuquan has been killed by Cao Zirong, and now the person in charge is to go to humility." This person used to be the Zuoxian King of the Southern Xiongnu, and now he has taken over the position of Da Shan Yu, and I am not very familiar with him, so I am afraid that he will not ......."

"How do you know if you don't try?" Zhong Changtong said: "If you can ask for help, the general will escape from death." ”

"Sir's words made me pause." Gao Gan then said to the two generals beside him: "Xia Zhao and Deng Sheng, you two are guarding Huguan, I will go to Hetao to see the Southern Xiongnu Dashan Yu Qubei and ask him for some help." ”

The two generals responded with their fists clasped and said in unison: "I wish the general success!" ”

Gao Gan left Huguan and headed for Hetao.

Soon, Huo Wu, who was hiding in Huguan, spread the news to Cao Shuo.

After receiving the news, Cao Shuo asked Guo Jia: "Feng Xiao thinks the Huns will send troops?" ”

"The Huns have already been beaten by Gongzi, how can they send troops?" Guo Jia said: "I heard that Zhao Qian, Huo Nu and others rebelled before, and they were broken by Tian Yuanhao. Wuhuan also sent troops to attack Xian Yufu, and Tian Yuanhao had to hold on to it due to insufficient soldiers and horses. Qingzhou reinforcements have not yet arrived, Cao Gong has already sent troops to help, it is precisely because of this that Gao Gan decided to rebel against the Cao family, taking advantage of the Cao family's air defense to recapture Yecheng. ”

"We hadn't landed in Hercy when this happened." Cao Shuo said: "But it's a good thing that I wasn't in Shouchun at that time. If I had returned to Shouchun, those rebellions would have been quelled long ago, how could Gao Gan dare to start a rebellion? ”

"That's what Childe said." Guo Jia said: "But Tian Yuanhao is really good, he can deal with all kinds of troubles." You must know that Youzhou is tired, and there are not many soldiers and horses available. ”

"If it weren't for his ability, how could I trust Youzhou to him?" Cao Shuo said: "Sooner or later, what the Wuhuan people do will pay a price. Now it depends on how the Southern Xiongnu choose. If they dare to send troops to help Gao Gan, it is exactly what I wish for. ”

"Could it be that Gongzi plans to take this opportunity to defeat the Huns and wipe them out completely?" Guo Jia asked.

"I've had this idea for a long time, but the Central Plains is not stable yet, and it's not good for me to do so." Cao Shuo said: "If you want to attack the Southern Xiongnu, you have to have a reason. ”

"I'm afraid that the Huns won't give Gongzi this reason." Guo Jia smiled slightly, thinking about Cao Shuo and asked, "When you get to Huguan, what is the son's plan?" ”

"What else can I do?" Cao Shuo replied: "Huguan is not an isolated city, even if we are besieged in the pass, the senior cadres can transfer grain and grass from outside the pass. If we besiege for ten years, he will be able to hold on for ten years, and the only way is to storm it. ”

"Assault?" Guo Jia glanced back and said to Cao Shuo: "I'm afraid that the soldiers and horses brought by Gongzi are not enough to attack." ”

"Although I don't want to destroy the Great Wall, since Gao Gan is stuck here, I can only reluctantly smash it with a catapult." Cao Shuo smiled: "As long as we smash a gap in the city wall, we can successfully attack the city." ”

"The Great Wall is different from ordinary walls." Guo Jia said: "If it is a city wall, the catapult can collapse in ten days and half a month, but the Great Wall is very strong, and it should be difficult for the catapult to have an effect." ”

"Whether it's hard or not, try it first." Cao Shuo replied.

He then instructed Chen Zhi: "Tell General Lu to advance quickly to Huguan, and when you get there, let the soldiers build fifty catapults first, search for stones everywhere, and we will prepare to attack the city." ”

Chen Zhi responded, and said to a dragon rider on the side: "Catch up with General Lu and convey the military order of the son." ”

Cao Shuo led a large army to Huguan, and Gao Gan also left with a group of men and horses, and rushed to Hetao to ask for help from the Southern Xiongnu.

Standing on the city wall, Zhong Changtong looked into the distance and asked the two generals, Xia Zhao and Deng Sheng: "Dare to ask the two generals, Cao Zirong personally led the army to come, how sure are the two of them that they can hold the Huguan?" ”

Xia Zhao said: "General Gao went to the Xiongnu for help, and asked us to defend to the death, as generals, we don't care about winning or losing, just guard the pass." ”
