In the evening, it was already dark.

Ma Chao, Lin Xiao, Lin Yuan, and Wei Yansi will return to the camp one after another.

Originally, at this time, Wang Ping, Ling Tong and other generals were going to lead troops to patrol around the camp.

But not tonight, all the soldiers gathered in the camp, and hurried to make a fire to make food, and after the meal was to start a military operation.

As for the scouts in Gaonu City, there is no need to worry, because after Manro's scouts were unable to approach the Han army camp a few days ago, Manro did not send scouts out to inquire about the news.

After the soldiers and horses had eaten dinner, it was already approaching the end of the day.

In the big tent of the Chinese army.

Liu Chan and a group of generals gathered in the camp.

Liu Chan looked at the hourglass in the center of the tent, saw that the sand in the hourglass had run out, slowly stood up, and shouted to the generals: "The time has come, the generals will listen to the order!" ”

"The last general!" All the generals looked upright and stood one after another, with solemn expressions.

Liu Chan took out the arrow from the table and said to the generals: "Wang Ping, Ling Tong, E Huan, Ma Dai!" ”

"The last general!"

"Each of the four of you led 1,500 soldiers and horses, divided into the four gates of Gaonu, bluffed first, and pretended to attack the city, but when you saw the city gate open, you led your troops into the city!"

"No!" The four generals took the order and gave the order.

Liu Chan took out another arrow and ordered: "Ma Chao, Lin Xiao, Lin Yuan, Wei Yan, the four of you led 3,000 soldiers and horses into the tunnel, but when you heard the shouting and killing in the direction of Gao Nu, you opened the tunnel with Gao Nu, led the troops out of the tunnel, opened the four gates respectively, and joined forces with the soldiers and horses outside the city, and took Gao Nu in one fell swoop." ”

"No!"

The generals received the general order and left one after another, and in a blink of an eye, only Liu Chan and Guan Yu were left in the hall.

Seeing that Liu Chan did not assign tasks to him, Guan Yu said unhappily: "Your Majesty, you still deceive me into being old and refuse to let me go into battle!" ”

"Second uncle, don't get me wrong!" Liu Chan smiled and said, "I and my second uncle, there are other important things to do. ”

Guan Yu was overjoyed when he heard this, and hurriedly asked, "I don't know what the matter is?" ”

Liu Chan explained: "In Gaonu City, there are 20,000 soldiers and horses, even if our army breaks through from Gaonu City, the inside and the outside should be combined, these soldiers and horses can escape a lot, Budu root in the north, they will flee to the north." Now there are 1,000 cavalry left in the battalion, and I and my second uncle led this 1,000 cavalry to the north to intercept them, and we can't let them escape! ”

"Okay!" Guan Yu was overjoyed when he heard Liu Chan's words, and immediately frowned, and said: "At this time, just let Weichen go, Your Majesty's golden body, how can you be in danger?" ”

Liu Chan smiled, waved his hand and said, "My martial arts, isn't the second uncle still at ease?" The second uncle quickly went to rectify the soldiers and horses, let's set off as soon as possible, so as to occupy a favorable terrain in the north! ”

When Guan Yu heard this, he arched his hand and said: "Back then, I fought side by side with my eldest brother, and I never let my eldest brother suffer the slightest injury, and today I will work with Your Majesty to ensure that Your Majesty is unscathed." Your Majesty waits, and the last general will go to straighten out the soldiers and horses! ”

"Go ahead!"

Soon, the Han army camp and soldiers and horses all moved.

Wang Ping, Ling Tong, Ma Dai, and E Huan each led 1,500 cavalry to Gaonu Simen.

And Ma Chao, Lin Xiao and his son, Wei Yan and other generals, led 3,000 soldiers and horses into the tunnel behind the camp.

The tunnel is more than 3,000 meters long, and all these 3,000 cavalry have entered the tunnel.

In the deepest part of the tunnel, there is a relatively wide cave.

Ma Chao and other generals were standing in the cave, and there were people holding shovels and soldiers holding ladders waiting on the side.

General Wang Ping soon led his troops to the city, and the four gates suddenly resounded with fierce shouts of killing.

"The enemy army is coming, quickly go to the city to defend!"

"Bell, bell!"

"Come on, the Han army is coming to attack the city!"

Seeing that the Han army was suddenly killed, and there was such a fierce shouting of killing, the defenders in the city mistakenly thought that the Han army was coming to attack the city, and hurriedly beat gongs and drums and shouted loudly.

However, after a while, the defenders of Gaonu City gathered on the head of the Four Gates.

Now the location of Ma Chao and the others is in the center of Gao Nu City, and Gao Nu is so moving, Ma Chao who is located below can naturally hear it.

The soldiers in the city rushed to the city, and the loess sand fell in the tunnel.

Seeing this, Ma Chao immediately ordered: "Gao Nu shouted that the sound of killing has risen, quickly open the tunnel!" ”

"Dig now!"

When the people heard this, they immediately waved their shovels and dug the loess above their heads.

The loess falls, forming a mound in the underground cave, which rises higher and higher, and the soil layer from the ground becomes thinner and thinner. The people were also covered with loess, but they didn't care, standing on the mound and not poking the soil layer above their heads.

I only heard a plop, a large piece of loess suddenly fell, a small hole appeared above the cave, looking up, a full moon hanging in the sky.

"Phew!" A man got up from the mound, didn't care about being covered in loess, and said to Ma Chao and other generals with an excited face: "General, it's through, it's through!" ”

Ma Chao nodded, pointed to the hole that was no bigger than the basin and said, "Okay, I'm trimming the hole bigger." ”

"Howler!" Several people went into battle together, divided by two by three, and the entrance of the cave was expanded to one zhang square.

"That's it!" Ma Chao stepped forward and pulled down the minfu and said: "We go up now, you wait to return to the camp from the tunnel, rest well, and wait to take down the high slaves, you will definitely be rewarded." ”

"Thank you, General, thank you, General!"

The people thanked them and retreated to the edge of the cave so as not to hinder the movement of the Daohan army.

"Up!" As soon as Ma Chao waved his hand, eight soldiers, each carrying a ladder, came to the bottom of the cave.

The soldiers set up the ladder, and the four generals Ma Chao, Lin Xiao, Lin Yuan, and Wei Yan respectively led their troops to climb the ladder, and the four of them came to the ground in just a moment.

Ma Chao followed his eyes, only to see that this is the center of the street of the cross in the city, the street is empty, looking around, only to see the fire on the city, but it is the soldiers and horses that have attracted the city.

The four of them each occupied a crossing, and led their soldiers to come immediately.

In just half an hour, the soldiers and horses were all on the tunnel.

Seeing that the soldiers and horses were all coming up, Ma Chao said to the three generals: "Three generals, let's each take seven hundred and fifty soldiers and horses to the four gates and open the city gates." ”

"I'm going to the east gate!"

"I'm going to the west gate!"

"I'm going to the south gate!"

"Then I'll go to the North Gate!" Ma Chao nodded, waved his hand and shouted: "Brothers, kill with me!" ”

Since there were no horses in the tunnel, Ma Chao ran to the north gate on foot with more than 700 people.

Gao Nu has a total of 20,000 soldiers and horses, evenly divided, and at this moment, there are also 5,000 soldiers and horses guarding the north gate.

About 7,500 people were at the head of the city, and 500 people were under the city gate, guarding the city gate to prevent the Han army outside the city from breaking through the city gate and killing in.
