Three Kingdoms open plug-ins everywhere

After leaving the city, Guo Jia said to Zhu Ling: "Wenbo, you have someone dig a hole for me under the wall of the three city gates and bury a large water tank, and have someone on duty day and night to listen. If you hear any movement, report it immediately." Give me."

Zhu Lingdao: "Feng Xiao, what you mean is that Yuan Shao wants to dig a tunnel, and the three mounds on the surface are a deception."

Guo Jia said: "Both are possible. What we are facing now is Yuan Shao. Yuan Shao still has a lot of resourceful people, so don't be careless."

"Hey, no matter how many advisers he has, he is still no match for Feng Xiao and you alone. He is false and real, and you only need a few big water tanks to solve all their conspiracies. By the way, you also use tricks to delay their time, so you just It is the most powerful." Zhu Ling praised.

"You still can't be careless, Xu Ziyuan has been famous for a long time, and Feng Yuantu is not an ordinary person, and the three mounds outside the city don't know which one is real and which one is fake?

Our task is still very heavy, the three city gates must be carefully guarded, maybe Yuan Shao's people will come up with other tricks. "Guo Jia didn't dare to be careless, even though he fought against everyone with one hand, he was not timid or afraid, let alone take it seriously.

But in such matters as teaching wisdom, one dare not underestimate carelessness.

To use Xu Dingchang's words, it is called contempt in strategy and attention in tactics.

Chapter 598 Tunnel Collapse

In the next few days, Yuan Shao's army feigned attacks and harassed from time to time, even at night they sent people to pretend to attack the city, and interfered with all aspects of the fourth school lieutenant army defending the city.

At the same time, the three mounds continued to pile up soil close to the gates of each city.

Five days later, the drums of war drummed again.

Teams of Yuan Shao's army pulled out from both sides of the mound, and each city gate has [-] people.

And this time, Yuan Shao's new catapults were also rushed out, and they were scattered in front of the army instead of gathering together.

Of course, there are also reasons for the small number of trebuchets. In short, it is also a lot of experience.

"Yuan Shao is really going to attack the city? He hasn't dug his tunnel yet, right?" Zhang Fei felt a little uncertain when he saw that the troops under the city had increased compared to the previous few days.

Guo Jia said: "The reason for making such a big commotion is to provide cover for the troops digging the tunnel. It should be completed within a few days. It seems that they dug very quickly. I thought it would take about ten days."

"What does Feng Xiao think should be done?" Zhu Ling asked.

Guo Jia laughed and said: "It's simple, hit me, the trebuchet hit me hard, not only on the two wings, but also on the front of the city. The stone bombs on the front use big stones, if they can collapse the tunnel, they can't The collapse will also cause some damage to his tunnel, so that Yuan Shao will spend a few more days."

"Gao! Hehe... I still honor the name of Xiao Gao."

Zhang Fei and Zhu Ling hurriedly ordered people to bombard the open space outside the three city gates.

"Retreat three hundred steps, and continue to beat the drum." Yuan Shao's troops immediately retreated when they saw the flying stones, avoiding the attack of the stone bullets, but they did not retreat very far, after all, they really came to provide cover.

The tunnel was about to be dug to the bottom of the city, and they wanted to take this opportunity to attack the city to cover up the sound of the excavation and attract the attention of the fourth school lieutenant.

It's just that Guo Jia saw the problem at a glance, and didn't point out Yuan Jun's plan. He just threw huge boulders from time to time to deter him, and he was also pretending to be stupid.

"Report! My lord, the tunnel at the South City Gate has collapsed, and all those who dug in have been buried inside."

In the camp of the Chinese army, someone suddenly came to report urgently.

Yuan Shao raised his eyebrows slightly and asked, "Can you still repair the gun? Where did it collapse?"

"My lord, the landslide occurred less than [-] steps away from the crossing. The ground in the south city is soft, so it may not be possible to repair it."

Nancheng is close to the Yellow River, and the geology is the most unstable, with a lot of sand and rocks, and the soil is soft. After the landslide, it is impossible to re-open the connection at the original place.

"Report! My lord, the tunnel at the west city gate has also collapsed."

Yuan Shao asked again: "Where is the landslide? Can it be repaired?"

The visitor replied: "My lord, the landslide is [-] steps away from the entrance. There are not many landslides. They are being repaired urgently. They should be able to get through again."

"Okay! As long as you can get through, tell the soldiers to work harder and strive to get through as soon as possible, and everyone will be rewarded." Yuan Shao felt a little relieved when he heard the words, and his face did not turn dark.

Soon the people from the North City Gate also came to report that there was no landslide in the North City, but a lot of sand fell, making it difficult to move, and the passage needed to be cleared, which might delay the progress of the excavation.

In the next few days, the advancing speed continued to increase, but Guo Jia in the city also continued to arrange people to throw stones, also to counter-interference Yuan Shao's underground excavation.

It took the eighth day like this, and the soldiers who listened carefully reported that they found the sound of digging tunnels at both the west gate and the north gate.

"It seems that Yuan Shao is going to launch a new round of onslaught tomorrow. Tell the soldiers to rest well. You don't need to arrange too many people to watch the night tonight. Just call more civilians and county soldiers." Guo Jia let the soldiers who listened mark the authenticity position, and then asked people to prepare the materials for encircling and suppressing the tunnel troops tomorrow.

The next day, sure enough, Yuan Shao strengthened the troops at the west gate and the north gate.

"Both gates have as many as [-] troops, or even [-]. It seems that Yuan Shao wants to attack the two gates, and he has confidence in both tunnels." Guo Jia looked at the deployment of Yuan Jun's troops outside the city. , and then said to Zhang Fei and Zhu Ling:

"The two city gates will be handed over to you, and I will be in charge of catching mice."

"Don't worry, there are those mounds that our people in Yuan Shao can't get up to the city wall. I'm going to blow them up this time." Zhang Fei has long disliked the mounds, because the highest point of the mounds exceeds the plain The city wall, Yuan Shao's people can look down from a high position, suppressing the top of the city.

If it wasn't for Guo Jia's deliberate paralysis of Yuan Jun, Zhang Fei would have wanted to bomb him a long time ago.

There is no way to let the mounds pile up close, let alone let people pile up so high.

Fortunately, Yuan Shao's eight days were not too rich. The horizontal surface of the mound was not wide, so the opponent's trebuchet was not set up on it, otherwise the pressure on the city would be even greater.

Of course, Yuan Shao didn't let the trebuchet be placed on the mound, in order to reassure the fourth lieutenant in the city, and he also didn't want to have a fierce confrontation with Guo Jia and Zhang Fei too early.

Because Xu You and Feng Ji knew very well that once they dared to move the trebuchet to the mound, Guo Jia in the city would definitely not allow it, and would destroy the mound in advance instead of a symbolic attack like the previous few days one time.

"Siege the city! First storm the time for a cup of tea, enter the tunnel and enter the city. After the troops who entered the tunnel pass by, send people from the front to attack the city gate. This time, Pingyuan City must be captured." Yuan Shao stared sharply. In Pingyuan City, he was full of ambition this time, and secretly dug two tunnels. So far, they have been standing smoothly. First, they have not been exposed in advance, and second, they are not collapsing. This is a good sign.

"It's my lord, this time I will definitely capture Pingyuan City and wipe out Zhang Fei and his Fourth Colonel." All the generals suddenly took orders and went down to command.

"kill……"

Countless Yuan Jun rushed towards Pingyuan City, and soon the trebuchets in the city began to exert force. First, they concentrated on the mound, and at the same time, they also shot elite crossbows.

Most of Yuan Jun on the mound was crushed to death quickly, and half of the small mound was also smashed down, and the loose soil scattered to both sides.

The sharp bed crossbow pierced into Yuan Shao's archer with a whistling sound, causing screams and screams.

"Shield Hand! Shield Hand! Hurry... Come to the front!"

The hoarse General Yuan Jun retreated while moving his shield hand up.

Yuan Jun still used the two-wing attack method. Five thousand and five thousand soldiers would charge on the two wings, carry the ladder to the bottom of the city, and then climb up.

However, he was still shot by the intensive crossbowmen of the fourth school lieutenant army in the city, causing a lot of casualties.

Of course, this time Yuan Jun also learned his experience. All his crossbowmen followed up, and under the cover of the shieldmen, they also rushed to the bottom of the city and counterattacked towards the top of the city.

Arrows from both sides come and stay with each other, and fly around the city above and below the city, carrying the soldiers of the other side.

The same is true for the trebuchets. Yuan Jun's trebuchets caught in the attacking team were scattered everywhere, and then kept throwing stones.

The catapults of the Fourth Colonel Lieutenant Army in the city could not catch Yuan Jun's catapults outside the city, so they had to disperse their attacks outside the city, unable to concentrate their efforts to destroy Yuan Jun's catapults.
