Zhang Yuan asked Zhao Xin to go back and rest first.

Then someone called Xiao Ding over.

Xiao Ding has always been the captain of Zhang Yuan's guard, and he can see Zhang Yuan every day, but he seems to be a little afraid of Zhang Yuan, and he doesn't dare to communicate with Zhang Yuan more.

It's already night, and I'm called, and I feel a little apprehensive in my heart.

"Hussar General, you're looking for me."

Zhang Yuan smiled at Xiao Ding.

"It's just you and me here, you don't need to be too restrained.

Sit down, I have something to tell you. ”

Xiao Dingmu nodded his head, when Zhang Yuan lectured Zhang Qian before, he was standing next to him.

At that time, he realized that this brother-in-law of his was a hussar general of the Great Han, and he was nothing.

Because even if his father Xiao Qing restored the marquis, he was very respectful in front of Zhang Qian.

A prince who doesn't have any real power, can't manage the fiefdom, and there is no official in the family to take care of it, which is actually very pitiful.

"Today, Marquis Zhao Xin is back, and the things I asked him to do have been done.

And then there are some important things I want you to do, but the danger is very high, I wonder if you are willing to risk your life? ”

Zhang Yuan didn't plan to tell him the matter before Xiao Ding made a decision, the matter of the Evil King Wuhuan Da Shan Yu is still the most confidential matter, except for the people involved, it is necessary to know, and it will be better for others not to know.

"Hussar General, tell me just how dangerous it will be."

"If you don't get your little life right, it's gone."

Zhang Yuan said very seriously.

And he felt that it might be a good thing to lose his life, if he was really caught by the Hun Dadan Yu Yizhi, and Xiao Ding revealed everything under torture, then Zhang Yuan would be finished if he didn't do it well.

The reason why Zhang Yuan didn't say it was so serious was because he was afraid that the pressure would scare Xiao Ding too much.

"So serious?"

Xiao Ding knew that it was possible to lose his life in a war, but he didn't know that he would lose his life before he started fighting.

"It's probably more serious than this, maybe your Marquis of the Xiao family will be thrown away from you again."

Zhang Yuan further tried Xiao Ding's psychological ability to resist pressure.

"What do I get if it gets done?"

Before he started to do it, he started talking about the conditions, which Zhang Yuan appreciated.

Zhang Yuan is not Liu Che, it doesn't matter if you talk to him about the conditions, but don't talk to Liu Che about the conditions.

Zhang Yuan has seen a person who can still live a very nourishing life after talking to Liu Che about the conditions, and that person is Dongfang Shuo.

"There will definitely be an official position of 1,000 stone when I go back.

No, after my Hussar General's Mansion is abolished, you will not find a home to settle yourself in. ”

The Xiao family's spirit has worn out in the past few decades.

The glory of the first hero of the founding of the Han Dynasty has been left with the title of a liehou.

Xiao Qing whispered when he saw people, not just to be able to revive the Xiao family.

But Xiao Qing whispered outside, but he didn't let Xiao Ding and Xiao Ruo lose face with him.

Xiao Qing has great expectations for Xiao Ding.

Before Xiao Ding followed Zhang Yuan this time, Xiao Qing had already entrusted everything that could be entrusted.

"Hussar General, I listen to you.

I'll do whatever you tell me to do. ”

"Aren't you worried that you've harmed the Xiao family?"

Zhang Yuan was a little curious, where did Xiao Ding get his courage.

In the previous period of contact, Zhang Yuan felt that Xiao Ding was a little cringe.

Xiao Ding hesitated when he heard Zhang Yuan say this.

"Hussar General: Actually, I've already guessed a few.

My father told me that there was only one situation on the battlefield that would kill my family.

That is to surrender the Huns.

If the Huns capture me, if I can survive, I will try to survive, so as not to cut off the Xiao family's incense.

If I can't bear it, I will try my best to commit suicide, and I won't let the Xiao family fall into the abyss because of me. ”

It seems that this eldest brother of mine still understands people.

Zhang Yuan likes to deal with such loyal and not stupid people, especially this kind of people who have been bound to his own community of interests.

"Now that you've made up your mind, so be it.

Come to me tomorrow morning to pick up a letter, and engrave the contents of the letter in your mind on the way.

Then you go to Yuyang City with Xihou, don't tell Xihou the content of the letter, the evil king outside Yuyang City will answer you.

After entering Yuyang City, I found the general Wei Qing and handed him my letter.

When he asks you to come back, you just come back.

I can't guarantee that the heart of the Evil King is on our side, so you could run headlong into their encirclement.

The reason why I didn't let the Marquis go was because he was a Huns, and if he was found out and switched to the Huns, he wouldn't have a little burden in his heart.

But you are different, you also said that if you are caught, you will choose to commit suicide, it is better not to commit suicide, and if you live, you will have hope of coming back. ”

"I know, I'm going to do it well."

Xiao Ding nodded heavily.

There is nothing inherently difficult, but the process is too dangerous.

Xiao Ding just did some things that ordinary scouts do, but Zhang Yuan needed a cronie to do it, which made Xiao Ding out.

"Go back and rest, and come to me tomorrow morning to get the letter."

"No."

Xiao Ding got up and left Zhang Yuan's room, and Zhang Yuan also took out a piece of paper and began to write something to Wei Qing to know.

Simply narrated the matter of the Hun Evil King's agreement to help the Han army and the rebellion of Wuhuan Da Dan Yu, and then began to write his own plan.

In the end, the time for the attack was agreed.

And let Wei Qing tell Xiao Ding the secret that only Zhang Yuan and Wei Qing knew before sending Xiao Ding back, and this secret was two words.

It's kind of a connector code.

This is to prevent the possibility that Xiao Ding will be arrested at the beginning.

Of course, Xiao Ding may also be a double agent after being caught, and go to Yuyang City to fool Wei Qing, and then get the secret.

Zhang Yuan doesn't care about this.

As long as Xiao Ding's people can come back to Yangdu Governor's Mansion, Zhang Yuan will be able to find out what Xiao Ding has experienced.

In fact, Zhang Yuan's main purpose is to protect himself.

Let him surrender and be able to return to the Governor's Mansion in Yaoyang.

In this way, Zhang Yuan's own life and safety were in his own hands, so that the matter of Xiao Ding's surrender would not reach Chang'an City, and Liu Che would punish the nine clans of the Xiao family and kill Zhang Yuan.

That's really going to be a lot of injustice.

The next day, Xiao Ding knocked on Zhang Yuan's door on time.

Zhang Yuan got up and stuffed the letter to him.

"Destroy it after reading it, don't let Zhao Xin see it."

In fact, except for the secret, Zhao Xin knew the content of the letter.

Zhang Yuan just wanted to try Xiao Ding.

In order to cultivate his eldest brother, Zhang Yuan also worked hard.

Seeing off the two eldest brothers, Zhang Yuan began to study the route to drive the Xiongnu army.

Either south of the Great Wall, not to let Yi Zhixian lead his army north across the Great Wall.

In fact, this route is the best.

There are not so many passes to the Great Wall.

As long as all the passes are blocked, Yi Zhixian can either let his hundreds of thousands of troops dismount and climb over the Great Wall, or he can only run eastward. vp

Running south is almost impossible.

Because to the south is the sea.

To the north is the Great Wall, and to the west is the coalition army chasing the Xiongnu army.

It's just that in this way, the reasons for fooling Wuhuan Da Shan Yu before have all been pierced.

The easternmost part of the Great Wall of the Western Han Dynasty stretched all the way to the Bohai Sea, which later became Shanhaiguan.

This section of the Great Wall was built as early as the Yan Kingdom, and then the Han Dynasty reinforced and extended it on the basis of the Yan Great Wall.

Compared to the Great Wall in Shuofang County, this one is a little simpler.

Because the Han didn't see the Wuhuan people as a threat.

The generations all the way to Shuofang County were the main targets of the Xiongnu's invasion, and the Great Wall there could be divided into the Great Wall of Hannei and the Great Wall of Hanwai.

What Zhang Yuan wanted was to drive the Huns all the way to Shanhaiguan, and when he arrived, it was really called the heaven and the earth.

It is also very important that Dahan did not set up checkpoints there, there were no cities, and there were not even residents.

Just built this Great Wall along the mountain range.

When the Huns got there, it was a dead end.

Zhang Yuan couldn't understand why the later emperors wanted to build a fortress in this place.

Originally, the nomads in Liaodong couldn't get over, as long as they repaired the Great Wall, they had to cross the Great Wall if they wanted to pass from here, and then there would be no war horses.

The whole Guancheng is here, and the door is open for people to come in?

The door of my house is always open, and I am happy to accommodate heaven and earth.

Zhang Yuan thought about it, he didn't really want to care about Wuhuan's attitude towards Danyu, as long as he turned against the water and then fell to the side of the Huns, it was not possible.

If the Hun army can get into this pocket, then that's it.

If you can't, run a little more and find other pockets for the Huns to drill.

......

Xiao Ding and Zhao Xin had already arrived outside the Xiongnu camp in the afternoon.

Zhao Xin pasted a pile of mud on Xiao Ding's face and hair, and made him also wear the clothes of the Huns.

Swaggered directly towards the camp.

The evil king of Hun introduced him to Zhao Xin yesterday to know the guard who guarded the gate, Zhao Xin walked to the gate and nodded at the man, and the general of the evil king opened the door for Zhao Xin.

The reason why I came directly during the day was to avoid searching.

When it gets dark, you are close to the camp of the Huns, even if you are a Huns, others will interrogate and interrogate.

And during the day, the guards of the Hun camp were too loose.

Hundreds of thousands of troops, where can Yi Zhixian manage it.

A mile or two away from the camp was full of Huns and Wuhuan people who were pouting their butts and defecating on the ground.

They also knew that they should be as familiar with the environment in which they lived, so they all ran outside the camp, and those who were too lazy to run were directly solved in the camp.

After entering the camp, Xiao Ding kept breathing.

Looking left and right, every Hun who passed by him looked like he was coming to arrest him.

"Don't look around, just keep your head down and follow me."

Zhao Xin was also worried that something would happen to Xiao Ding, so he lowered his voice and muttered.

Xiao Ding immediately withdrew his glance and followed Zhao Xin to the camp of the Evil King.

The Evil King is not there, but he has already explained to the guards at the door, and Zhao Xin can enter and leave his camp at will if he comes.

The Huns did not have the habit of remembering, and they turned the big tent of the evil king upside down, but they could not find the slightest secret of him.

"Xihou, that's how we came in."

Xiao Ding still had a feeling of disbelief.

"It's easy to get in, but it's hard to get to Yuyang City."

Zhao Xin found a place to lie down.

It was very simple to enter and exit the camp of the Xiongnu army during the day, but at night, Yi Zhixian sent scouts to prevent the Han army from attacking at night.

These scouts will be Xiao Ding's biggest obstacle.

Zhao Xin didn't have to accompany Xiao Ding to Yuyang City at night anyway, he just needed to rest honestly in the king tent of the Evil King.

It may be that Zhao Xin came, and the guards outside the account ran to tell the evil king, and after a while, the evil king pushed open the curtain of the big tent and walked in.

Xiao Ding was taken aback.

"This is the messenger sent by Zhang Yuan?"

The Evil King pointed at Xiao Ding and asked.

Zhao Xin shook his head.

"He's only in charge of contacting the Great General Wei Qing, and he doesn't have anything in his mouth that the Evil King wants to know.

When the night came, he also asked the Evil King to send a scout team to send Xiao Ding to Yuyang City. ”

As long as Xiao Ding escaped the scouts under Yi Zhixian's hands, it would not be difficult to get under the walls of Yuyang City.

It's so dark, change into black clothes.

If you are a little faster and a little sharper, you can sneak directly to the city gate.

"Okay, I'll arrange it after dark."

The Evil King knew that Xiao Ding would not reveal anything, and his interest in him was lost.

Xiao Ding felt a little unrealistic when he saw the king of the Huns talking here about helping the Han people.

The time soon came.

It was the darkest time of the day, and just in time for a dark cloud to obscure the moon.

The Evil King immediately sent a ten-person scout team to escort Xiao Ding to a place a mile away from Yuyang City, and if they got closer, they might be discovered by the Han army on the city wall, or by the Hun scouts who were moving around.

So Xiao Ding quickly ran to the gate of Yuyang City alone.

The Han army on the city wall may have noticed some black shadow scurrying under the city wall, so they shouted.

"What people!"

Xiao Ding ignored the voice, and he replied now that it wasn't for the Hun scouts to find out where he was.

The Han soldiers on the city wall only shouted, and then thought that they had seen it wrong, or that some animal had run over.

Xiao Ding quickly stuck to the base of the city wall of Yuyang City, gasped for breath, and then entered the city gate hole and knocked on the city gate.

"Knock knock."

Although there are no soldiers of the Han army outside Yuyang City, there are Han soldiers everywhere in the city, and the soldiers who keep vigil on the city wall inside the city gate are doing what they have to do.

Like sleeping.

The soldiers who can really hold on all night without sleeping, and have been watching the movements around them intently, must only account for a small part.

As soon as Xiao Ding knocked on the door, he frightened the Han soldiers who were sleeping by the city gate.

"What's outside the door?"

"It looks like a human."

"Huns?"

"The Huns didn't sleep in the middle of the night and came to knock on the gate of our Yuyang City, what are you doing."

"What if it's a night attack."

"Have you ever seen a night raid and knock on the gate to alert your enemies?"

Several Han soldiers and soldiers in the city gate argued, but no one dared to open the city gate to take a look, and their lives had to be finished if something really happened.

Xiao Ding also faintly heard the argument inside the door.

"The brothers in the city open the door, I am a messenger sent by the hussar general Zhang Yuan, I want to see the general."

"This man says he's a messenger?"

"You can believe what people say, the Huns surrounded us so tightly, and the messenger flew over?

If he can fly, then what kind of door will he knock on, just fly directly to the Taishou Mansion to find the general. ”

"Whether it's or not, notify the tun chief first."

Xiao Ding was about to cry, shouldn't he knock on the door, the soldiers in the door should have gone to inform their superiors, they just made him wait for so long.
