Yuan Jun shot arrows for a whole day, and finally stopped at night.

In the dark night, more than a dozen black shadows jumped under the wall.

Each of them carried a clay pot in his arms, went under the wall, opened the clay pot, and poured something on the ground.

After pouring the first can, the black shadow who took the lead nodded, and more than a dozen people retreated.

Before they could retreat, they were immediately replaced by more than a dozen others.

The ground was filled with an unknown amount of liquid, and the shadows flicked one after the other, and these were removed, and others were immediately replaced.

Standing in the distance, Cao Cao looked at the dark wall.

"Can this really resist Yuan's sneak attack?" Cao Cao asked Cao Shuo on the side.

"It should work." Cao Shuo replied: "If the Yuan army wants to sneak attack, it must come underground, and as soon as they arrive, we will set a fire." After pouring so much oil, even Yuan Jun who was underground must have been roasted on the outside and tender on the inside. ”

"It's not bad to think about it, I'm afraid that Yuan Shao will see it." Cao Cao said: "With so much oil poured on the ground, even if Yuan Shao is stupid, he shouldn't let people dig tunnels easily." ”

"I heard that there is a man named Li Zhi under Yuan Shao." Cao Shuo said: "He is the commander of the digging battalion, and he is especially good at drilling and digging holes. With this person, what kind of tunnel does Yuan Shao dare not dig? ”

"How can I hear something unusual in your words?" Looking at Cao Shuo, Cao Cao asked.

Cao Shuo smiled and said to Cao Cao: "Father is a noble person, generally speaking, some things and people who can't be on the stage are disdainful. But I'm different, I'm interested in these kitsch things. ”

"I knew you wanted that Li Zhi." Cao Cao said: "Okay, I won't rob you, if you can not burn him, get him in your hands and hand it over to you." ”

"Thank you, father, for making it happen!" Cao Shuo hurriedly thanked him.

The Yuan army has not yet launched an attack, and the father and son have begun to divide the commander of the digging battalion under Yuan Shao.

If Yuan Shao knew this, he would definitely spit out a bucket of blood in anger!

After the whole night, the ground under the high wall was greasy and greasy, and when seen from the dirt slope where Yuan's archers were, the land was black and shiny.

On the dirt slope, Yuan Shao stood with his hands on his hips.

Looking behind Cao Jun's high wall, Yuan Shao said, "What is Cao Mengde doing? The ground was dark, and I didn't know what it was. ”

"Oil." Guo Tu said on the side: "He must have expected our army to attack from the ground, so he poured oil on the ground, trying to wait for our army to go up from the ground and burn our soldiers to death with fire." ”

"Then I'll set a fire first and let all his oil be poured in vain." Yuan Shao commanded to the side: "Archers, shoot rockets and burn all their oil." ”

The archers of the Yuan army spread their longbows one after another, and set up flaming arrows on the bowstrings.

With an order, countless rockets fell behind Cao Jun's wall.

The rocket fell to the ground, ignited the fuel, and a raging flame rose into flames.

The flames burned, and immediately Cao soldiers ran to report to Cao Cao.

Getting the news, Cao Cao ran out of the barracks.

When he saw the raging fire blocking the high wall, his brows tightened, and he shouted to Xu Chu in annoyance: "Go and call Zirong!" ”

Xu Chu just answered, and before he could turn around, Cao Shuo had already run over.

"Burned?" When he came to him, looking at the burning flames, he grinned and asked.

"All the oil was poured in vain." Cao Cao said: "Yuan Shao's fire ruined everything we did last night......

"It's okay to ruin it, continue to fall tonight." Looking at the raging fire, Cao Shuo was not only not a little depressed, but smiled very happily.

"What are you laughing at?" was annoyed, Cao Cao asked him angrily.

"I laugh at Yuan Shao's stupidity." Cao Shuo said: "After the soil is burned by the fire, it is masonry, and we just need to pour some oil on it every day. If Yuan Jun doesn't burn it, we will burn it ourselves. I see what they use to make a hole in the ground. ”

Cao Cao was stunned and looked at Cao Shuo in amazement.

"There are still two days left to complete the construction of the Thunderbolt." Cao Shuo continued: "Once the thunderbolt knocks down their arrow towers, I will see how they can make a hole in the ground and sneak attack from the ground. ”

Cao Shuo's words stunned Cao Cao.

He only thought that the oil was burned, and once Yuan's army came out of the ground, Cao's army would be defenseless.

But he didn't expect that the fire-burned soil would be as hard as stone.

Looking at Cao Shuo in amazement, Cao Cao finally showed a long-lost smile: "It's still your ghost idea, I'm just afraid that Yuan Benchu will know your plan and will be annoyed by you and spit out a basin of blood." ”

"Unfilial!" Raising his hand and pointing at the tip of Cao Shuo's nose, Cao Cao said: "No matter what, Yuan Benchu is also your father-in-law, and you actually used such a method to treat him." ”

"Only then did the father know the child's difficulties?" Cao Shuo said with a bitter face: "Isn't it all for my father when I do this? ”

"I know you're wronged." Cao Cao said: "When the war is over, I will reward you well." ”

"Actually, I have a reluctant request." Cao Shuo suddenly became serious, he hugged his fists and said to Cao Cao: "If my father breaks through Hebei, can you not kill my father-in-law?" ”

"Are you interceding for Yuan Benchu?" Cao Cao frowned: "Have you ever thought that if it was me who lost, would he spare me?" ”

"Father won't lose." Cao Shuo said in a very affirmative tone: "As long as I am here, the Cao family will definitely win this battle!" ”

"What a big breath." Pointing to Yuan's army in the distance, Cao Cao said: "Yuan Benchu commanded more than 200,000 soldiers and horses, but our army only has 40,000 or 50,000, plus the 20,000 you brought, it is only 60,000 or 70,000. You tell me, how can I win against him? ”

"There are many examples of winning more with less." Cao Shuo said: "Back then, King Wu was defeated, and in the battle of Muye, how many men and horses did the Zhou army have? How many men did the merchant army have? Didn't he break through Chaoge and force Shang Xuan to self-immolate in the Star Picking Tower? The battle of Xiang Yu Julu was also a victory with less, capturing countless Qin troops. Now in this battle of Guandu, I can say that it must be my father's victory! ”

"You're going to be dismissive." Cao Cao smiled and said: "I didn't have much confidence, but today I saw Yuan Benchu burning the muddy land, and the success is a little more." ”

The fire is still burning.

The raging flames reflected the faces of Cao Cao and the others.

Cao Cao's face had changed from the initial gloom to a smile on the corner of his mouth.

Yuan Shao on the dirt slope was also smiling at this time, looking at the place where the flames were burning with satisfaction.

"Order Li Zhi and let him lead the troops to dig a hole." Yuan Shao said to Guo Tu on the side: "Give him half a month to dig the hole behind the Cao Jun Wall." ”

"Yuan Gong is wise, as long as our army opens up the tunnel, Cao Cao will not be captured?" Guo Tu lost no time in patting his ass.
