Zhang turned around and glanced at Dian Wei beside him. Dian Wei understood, came out of the crowd, and thrust the double iron halberd into the ground and into the earth for half a foot. Then, he hooked up a clay pot with one hand, swiped it twice in his palm, and threw it forward. The clay pot streaked a curve in the air, right in the center of Yuan's formation.

Even if the soldier Yuan who was hit reacted quickly enough to protect his body with a shield in time. But those terrible black, slimy liquids were still scattered and splashed in all directions, staining the bodies of more than a dozen people. Dian Wei laughed cruelly, manipulated the halberd with both hands, swung it hard, made a loud "dang" sound, and shouted:

"Whether it is a battle or a surrender, it will be decided in a word!"

"If you don't surrender, you will fight!"

These days, after experiencing fierce siege battles, for the soldiers of the Yuan army, Dian Wei can be regarded as fierce. Those Yuan Jun who were trapped in the city did not know the terrible of this one. When the surrounding Bingzhou troops saw Dian Wei coming forward, they also immediately shouted loudly in agreement:

"Drop! Fall! Fall! ……”

In the face of Dian Wei's direct deterrence, Yuan Jun finally moved. One of Yuan soldiers threw his weapon to the ground, which immediately triggered others to follow suit. But listening to the sound of "clanging" for a long time, most of the Yuan army had already disarmed their weapons. At the moment, he is still holding a sword, but only one or two percent.

"Empty-handed, come here! Lao Tzu invites you to eat meat! ”

A loud and vulgar voice sounded, but it was Liao Hua, who was originally in charge of guarding the north, shouting. Liao Hua is not very old, but he has grown up in the army since he was a child, and he knows the thoughts of ordinary soldiers best. If it is said that among the generals of the state army, the one who can get along with the soldiers the most, it is none other than him. Even if everyone said the same thing, it was Liao Hua who was the most convincing to the soldiers.

"Damn, come on! It's late. But there's no meat to eat! ”

Liao Hua shouted a few times one after another, and immediately dispelled the fear of Yuan Jun's surrender a lot. Soon, a group of empty-handed Yuan soldiers set off together after a small tandem and walked towards Liaohua. And there are those who take the lead, those Yuan Jun who have a surrender in their hearts. Jump on the bandwagon.

In just half an hour, except for nearly 100 Yuan soldiers who were still holding weapons, everyone else obediently entered the inner city area and became prisoners of the state army.

"Drop or not!"

Dian Wei carried the double iron halberd and strolled towards Yuan's army. Even people who feel sluggish can sense that Dian Wei is really planning to do it. With the remaining hundred or so people, I am afraid that Dian Wei alone will be able to kill them all. Lives are at stake. All the soldiers of Yuan kept turning their necks at this time, looking back and forth at Dian Wei and an officer with excellent battle armor.

"I'm willing to ......"

Being watched by his subordinates, the officer finally couldn't bear the pressure of nearly a hundred people's lives and deaths, and spit out such a sentence from his mouth with difficulty. As soon as he said this, the rest of the Yuan soldiers also let out a sigh of relief, and simply threw their blades to the ground.

So, Yuan Jun's wall-breaking assault operation. This is the end of the story. All those who broke into the city took the initiative to send Guo to the next level. All of them were captured.

The battle is over, but the battle continues.

On the other hand, around the breach of the collapsed wall, it was necessary to continue to build long walls for defensive operations. Fortunately, this matter was taken over by Zhao Yu on his own initiative, so he didn't have to worry about it. When everything was sorted out, the arrogant spirit relaxed. Only then did I feel the severe pain of the broken arm.

Even though he was exhausted and the pain of the injury was extremely intense, he still couldn't get a good rest. At this time, there is a question in the heart of the arrogance that must be answered. Otherwise, his heart would not be at peace.

Why did the walls collapse suddenly?

This question. Not only was Zhang arrogant and eager to find out, but the rest of the soldiers of the state army were also extremely curious about this. To put it more seriously, this is a major matter related to whether the city can continue to hold on.

It's not that difficult to figure out this question. Just ask the captured Yuan Jun to find out the answer. Maybe the ordinary big-headed soldier will not know the reason. But with the status of Guo Yuan, the captain of the Yuan Military Academy, he can definitely know the answer.

Speaking of Guo Yuan, he is not an unknown person. He was born in the Guo family, a famous family in Yingchuan, and belonged to the same family as Yuan Shao's adviser Guo Tu and his arrogant adviser Guo Jiafen. It's just that, compared to Guo Jia's side branch status, Guo Yuan can be regarded as Guo's descendant. Moreover, his mother is the younger sister of the current calligrapher Zhong Xuan, and she is also a good learner, which can be called a typical scholarly family.

With such a good background and family education, Guo Yuan's road to study can be described as smooth. It's just that Guo Yuan has liked to practice martial arts more than to learn literature since he was a child. As an adult, Guo Yuan is actually quite accomplished in the classics, but he likes to show off his swordsmanship in front of everyone the most.

The Yingchuan scholars of the same generation saw that Guo Yuan was good at martial arts, and they teased him that he was the next "Ban Dingyuan" of the Han Dynasty. Whenever he heard such words, Guo Yuan was not angry, but extremely happy.

Therefore, since the chaos in the world and the situation of the division of the princes appeared, Guo Yuan followed his cousin Guo Tu and came out of the shogunate of Yuan Shao, and finally had a place for him. Because Guo Yuan liked to practice martial arts, Yuan Shao handed over a group of soldiers and horses to him and used them as generals.

Among the generals of the Yuan army, Guo Yuan's ability is not outstanding, but it is also above the level. And because of his superior background, Yuan Shao has always been extremely fond of him, and regards Guo Yuan as one of the most reliable cronies around him. Being able to succeed Gao Ran and become the second commander of the Yuan Army's commando fully illustrates Guo Yuan's status in Yuan Shao's mind.

So, Yuan Shao values it so much, why didn't Guo Yuan fight to the end, but finally surrendered?

If Guo Yuan was a simple martial artist, this kind of behavior would make him despised in the future. However, who made Guo Yuan from a scholar family?

As a scholar, when things cannot be done, he will protect himself wisely and wait for future use, which is great perseverance and wisdom. Don't you hear the "humiliation of the crotch", and you can also become a generation of beautiful talkers?

Moreover, Guo Yuan does not think that he has surrendered to arrogance. He was obviously exhausted by hard fighting, so he was forced to be captured by the enemy, okay?

As long as Guo Yuan does not act under Zhang Qiang, Yuan Shao's side will not think that Guo Yuan is a "thief". Anyway, Julu City can be conquered overnight, and when the Yuan army conquers Julu, it will naturally be able to rescue the captured Guo Yuan. He, a loyal minister of the Yuan family, can still continue to serve Yuan Shao as before. At most, Yuan Shao will be slightly alienated from Guo Yuan in the future, and he is not worried about letting him continue to lead the troops.

With such a superior mentality, Guo Yuan answered the question of the Bingzhou Army very happily. Of course, his answer also has a bottom line, limited to those things that Guo Yuan thinks does not need to be kept secret. But as long as the state army makes some efforts, the news that can be learned, Guo Yuan has no intention of keeping it secret.

As for why the city wall collapsed suddenly, even if Guo Yuan didn't say it, Zhang Qi could finally figure it out after careful investigation. There is no need for Guo Yuan to deliberately conceal this kind of thing.

As for the answer given by Guo Yuan, it is not much different from Zhang Qi's original conjecture.

Because of the authentic.

Since the beginning of the siege, Yuan Jun has been digging tunnels. Those tunnels were clearly placed not far from the city, and as long as the defenders were not blind, they could see when they looked up. Even the soil transported during the excavation process was directly piled up by Yuan Jun between the tunnel entrance and the city wall, and a small mound was stacked to defend the attack in the city.

People who have enough experience in the excavation of the tunnel can estimate the approximate progress of the tunnel even by looking at the amount of earthwork piled up at the mouth of the tunnel. It's a pity that there is no such talent under Zhang Qiang. However, for the excavation progress of Yuan Jun's tunnel, the arrogant side can still roughly estimate.

Originally, according to the excavation progress of Yuan Jun and the listening signal from the underground listening place, Yuan Jun's tunnel should have been dug to the city wall a few days earlier, and it could lead to the city. For this reason, Zhang Qiang has prepared special gag equipment, ready to give Yuan Jun's tunnel a good look as soon as it is discovered.

However, no one thought that the tunnels of the Yuan army, which lacked experience in defending the city, did not want to go directly to the city, but to dig down the city wall!

The walls of the giant deer were built quite deeply, and the foundation was more than six feet deep. To hollow out a wall that is more than five feet thick and collapse it entirely, the amount of earth required is enormous.

However, Yuan Shao has a "digging team" composed of miners [miners], who are experienced in how to dig space underground. Moreover, the top soil of the giant deer is all soft loess formed by river deposits, and excavating this soft soil is several times easier for the members of the digging team than beating in the rock crevices between the mountains.

The leader of the digging team is a Pengguan who has worked in the mine for nearly 30 years. He has extensive experience in what kind of tunnels will collapse and how to avoid them. Therefore, if you want to dig down the giant deer city wall, although it is a little difficult, it is still difficult for the digging team.

In order to make the city wall fall and collapse, the leader of the digging team made the entire excavation plan after a visual inspection. They hollowed out about three-quarters of the foundation directly below the walls of the giant deer, leaving only a quarter of the ground intact to support it. In order to prevent the city wall from falling down in advance, the digging team also used thick wooden stakes to withstand the hollowed out foundation.

After an underground cavity nearly ten zhang long and more than four zhang wide was formed, the excavation team withdrew from the tunnel, poured the grease from the lamp on the wooden stakes supporting the tunnel, and lit the flames. As a result, the stakes begin to burn and the resulting smoke is constantly emitted from the vents in the tunnels.

The smoke that rose from the ground attracted the attention of the defenders of the city, and as a result, dozens of defenders were led to the city. It's a pity that these rookies who don't have much experience in defending the city don't know what the smoke represents.

When the wooden stakes were burned one by one and could not support the weight of the city wall, the previous massive collapse of the city wall occurred, and a series of fierce offensive and defensive battles followed. (To be continued......)
