Then, Yu Fuluo said confidently: "I saw the mouse first, and if you think of this method, you have to have at least one-third of my credit." ”

Yu Fuluo's two major skills, throwing the pot and grabbing credit.

Not to mention the others in the camp, even his own son Liu Bao can't stand it.

Liu Bao stabbed Yu Fuluo with his elbow below, which meant to say, "Dad, can we not be ashamed?" ”

"So many people, look at it!"

This is a man who does practical things, and he is too lazy to argue with Yu Fuluo about this kind of thing.

Immediately began to draw engineering drawings, planning how to dig the tunnel, all the way to the front of Liucheng.

If you say, the original collapse is not sure of capturing Liucheng at all.

Now, after thinking of this method, he is at least seventy percent sure.

Three days later.

On the walls of Liucheng.

Prime Minister Cao Cheng was wearing a big red robe, standing on the city wall with the Heavenly Sword in his hand, looking at the busy grassland aliens under the city.

"Prime Minister, they're not attacking!"

"What do you look like you're digging?" Yu Ban reported to Prime Minister Cao Cheng.

Prime Minister Cao Cheng is an old fighter, and he has been fighting for half his life.

After learning that the enemy forces outside the city were digging, Cao Cao immediately understood their intentions.

I saw Cao Cao's face sinking like water, and he said in a gloomy tone: "There are two brushes in this collapse!" ”

"He wants to dig a tunnel and use it to get closer to the city."

"As soon as this tunnel is completed, our catapults and ballistas will lose their effectiveness. At that time, Liucheng will be in danger. ”

Prime Minister Cao Cheng's voice fell, and Jia Xu, the military advisor on the side, said: "Not only that, you see, the earthworks they transported out are all piled up together. ”

"He also wants to pile up a mountain of dirt and then have the archers shoot at us."

After hearing Jia Xu's words, Cao Cao couldn't help but sigh: "It is said that this collapse is resourceful, and when I saw it today, it really deserved its reputation." ”

"If you don't die, it's hard for me to settle on the Han frontier!"

At this time, Xu Huang, the general on the side, gave an order: "Lord, you give me a soldier and horse, I will harass the enemy army, and they are not allowed to dig the soil." ”

Jia Xu hurriedly said: "No, never!" ”

"Outside the city is the enemy's camp, and General Xu Huang is bringing more soldiers and horses, it will also be a wolf!"

Cao Cao looked at Jia Xu and asked, "Wenhe, we can't just watch them dig the tunnel!" ”

"This tunnel is complete, and Liucheng is not guaranteed!"

However, Jia Xu smiled slightly and said, "Prime Minister, don't worry, don't worry." ”

"Digging a tunnel, it's a big job. If they want to dig under our walls, it will take at least ten days and half a month. ”

"Don't forget, we still have a strange army?"

"Perhaps, before they dug up our city, Wuhuan Mountain has already been taken by Gongzi."

"Of course, we can't sit still."

"The prime minister can send troops to harass them and slow them down the speed at which they dig tunnels. However, troops could not be sent from Liucheng. ”

"Liucheng is the front, the frontal troops are the decisive battle, and the flank troops are the attack."

"The lord can fly pigeons to pass the book, and let General Cao Ren and General Xiahou send troops from the White Wolf Road and Jieshi Road."

"Attack the enemy from the left and right flanks to delay their digging of tunnels."

Cao Cao pondered for a moment and felt that Jia Xu's method of sending troops to attack and harass on the flanks was indeed good.

Even if he didn't send troops to attack and harass, it would take ten days and a half months to dig a tunnel that could allow 100,000 people to reach the city wall.

If there were any more troops, it would take at least twenty days.

Su Ming and the others have been setting off for several days, and in another twenty days, maybe the news of Su Ming's attack on Wuhuan Mountain will come back.

At that time, if you don't withdraw your troops, you will have to withdraw your troops.

Cao Cao Feige passed a book, ordering Cao Ren and Xiahoudun to send troops to attack and harass from the White Wolf Road and Jieshi Road respectively.

Cao Ren sent Cao Hong to lead 30,000 cavalry, and Xiahou Yuan also sent Xiahou Yuan to lead 30,000 cavalry.

Cao Hong and Xiahou Yuan each led 30,000 cavalry, one on the left and one on the right, to attack and harass every day.

They didn't fight hard, but they rushed to the place where they dug the tunnel when they were unprepared, and there was a flurry of arrows.

These soldiers digging tunnels are not armed with weapons and equipment, and they have no power to fight back! I had to hide in the tunnel and wait for reinforcements.

When their support came, Cao Hong and Xiahou Yuan evacuated separately.

These days, these people digging tunnels are overwhelmed.

In three words, it's annoying.

Wuhuan Battalion.

"Grandma's!"

"Those eight calves of the Han people are as slippery as loaches, and they let them run away!" Yu Fuluo scolded and complained.

Wuhuan, Xiongnu, and Xianbei are working in turns.

Every day, two families send people to dig tunnels, and one family sends people to guard, which rotates every day.

Today it is the Wuhuan and Xianbei people digging tunnels, and the Xiongnu people are on guard.

In order to prevent a sneak attack, Yu Fuluo personally led people to guard today.

However, Cao Hong and Xiahou Yuan were both slippery like loaches, and if they changed places with one shot, he couldn't catch them at all.

Moreover, the defenders on the city wall will also provide long-range fire support to Cao Hong and Xiahou Yuan.

Sometimes, even if they are surrounded, Cao Hong and Xiahou Yuan can move close to Liucheng and evacuate with the help of long-range fire support on Liucheng.

Yu Fuluo had no way to deal with these attacking cavalry, so he was naturally angry.

Compared with the angry Yu Fuluo, Collapse was very calm.

"You're not angry?" Yu Fuluo asked with some curiosity.

Mudon replied very calmly: "They sent troops to attack and harass all day long, which shows that they are afraid, and our method is useful." ”

"Even if they send troops to attack and harass, in twenty days at most, our tunnels can be dug under Liucheng City."

"At that time, it will be time for us to take Liucheng in one fell swoop."

"Why should I be angry, it's too late for me to be happy now!"

"Keep digging, as long as we keep digging, there will naturally be times when they can't hold their breath."

Collapse has already made up his mind, no matter what, no matter how much Cao Cao sends people to attack him, he will keep digging.

Anyway, these small groups of cavalry could only delay the progress of his project, and could not play a decisive role.

He just kept digging like this, just to delay some time.

If Cao Cao left the city halfway and fought them in a decisive battle, it would be the best.

After all, once out of the city, Cao Cao's army had no advantage over the city walls.

If Cao Cao had not left the city, they would have been able to attack on a large scale when the tunnel had been dug under Liucheng.

At this time, in Crash's heart, he took Liucheng, and it was already nine out of ten, it was only a matter of time.

Now, he is already studying how to take down the entire Youzhou.

As everyone knows, a cavalry led by Su Ming has already touched his base camp at this moment.

That is, Wuhuan Mountain has descended.
