The rampage of the Black Mountain Army caused the prosperous city to fall into a devastated state in a short period of time.

On this day, countless people were killed or injured in the city.

In addition, the Black Mountain Army looted more materials and equipment than Zhang Yan expected. With these equipment, the Black Mountain Army can arm some soldiers in a short period of time, and the ability to defend the city will definitely be stronger than now.

This kind of gain is a good thing for Zhang Yan, but for those who intend to surrender to Pan Feng, it is a bad thing.

Perhaps Zhang Yan himself did not expect that his actions not only did not make those with dissentful intentions honest, but instead increased their anxiety.

After this plunder, the aristocratic families and people in the city were full of hatred for the Black Mountain Army from top to bottom. If the Black Mountain Army wanted to withdraw from the city later, then these hatreds would not be taken seriously at all.

But the current Black Mountain Army is surrounded in the city. In other words, before Pan Feng leaves, the Black Mountain Army will stay with the aristocratic families and people in the city that hate them.

This is undoubtedly a very dangerous thing.

Only a thousand days of being a thief can you defend against it? Those who are determined to surrender to Pan Feng believe that Zhang Yan will surely perish if she continues like this.

And they must escape from this cage before Zhang Yan can destroy it wildly.

......

In a big mansion in the city.

This was originally a wealthy family's house, but now it has been occupied by a general from the Montenegro army and has become his mansion.

Now, there are smashing, looting and burning everywhere in the city, but this house is not harassed because there are Black Mountain soldiers guarding the door.

At this time, in the secret room of the house, eight or nine Black Mountain generals wearing armor were gathered together to discuss major events.

"Zhang Yan's actions are to force our Heishan Army to a dead end." A general said with a bitter face.

"That's right. When I went on patrol yesterday, many people looked at me in a bad way. I always felt that someone was going to rush out to kill me." Another person said.

"Ha, you don't know that more than a dozen people in our army have been secretly murdered, and many of them were killed after being alone, so let's bring more people when we go out." Someone kindly reminded.

Killing relatives, insulting wives and daughters, and cutting off people's wealth. Any one is an irreconcilable hatred. It is natural for those who are still alive to kill the Black Mountain Army, but now the Black Mountain Army has an absolute upper hand, so it can temporarily stabilize the situation in the city.

But this is not a long-term solution after all. Once the city wall changes, the aristocratic families in the city will definitely take action. By then, the Black Mountain Army will face the situation of being attacked on both sides. By then, the Black Mountain Army will not be far away from destruction.

In the secret room.

Everyone complained with each other, making the atmosphere in the venue gradually become pessimistic.

At this time, a man who had not spoken among the few people suddenly spoke.

"Since you are all so distressed, why don't you find a way to get rid of Zhang Yan and join General Pan Feng?"

As soon as these words came out, everyone in the audience was shocked.

The words "Submission to Pan Feng" have become almost a taboo in the city. Anyone who dares to mention these four words, whether they are generals or soldiers, will be executed on the spot on the grounds of disturbing the morale of the army at the worst.

Even if everyone is gathered together now, even though they know their own general thoughts, they still dare not mention these words, let alone put them together with getting rid of Zhang Yan, but now someone has finally put them up.

"Shao Shen, I'll gather in private. You know the reason. If there is really a way to do it, I'll have already started!"

The general named Shao Shen glanced at the other party and chuckled: "If there is no way, I won't mention this."

Everyone's eyes lit up. Shao Shen seemed to have made a decision when he heard this tone!

"Since that's the case, what are your good plans?"

Shao Shen took out a letter from his arms slowly.

"We don't dare to take good advice. We just need to send a letter to the camp in Jizhou to let General Pan Feng lead his army to attack the city. As long as General Pan Feng attracts Zhang Yan's attention, our troops will make a difference in the city. Even if we can't kill Zhang Yan, we can still live and break through the city gate."

Everyone's eyes lit up.

It may not be possible to send a group of people out, but with their rights, it is still easy to send a messenger out.

"Since that's the case, I'll make arrangements now and send the secret message outside the city tonight!"

......

That night, Pan Feng in the camp received a secret letter from the city.

After reading the secret letter, Pan Feng's eyes were full of murderous aura.

He didn't expect Zhang Yan to be so crazy. According to the letter, the city was full of sorrow, and now there are even more than one hundred that can be completed.

In addition to this, another thing mentioned in the letter also made Pan Fengxin worry.

That is, Zhang Yan has already started to use the collected equipment and iron weapons to arm his soldiers. If Zhang Yan is given some time, then he will have to spend more manpower and material resources to capture this city!

Thinking of this, Pan Feng secretly called luck.

If it weren't for the letter from the city, he would have been kept in the dark. Fortunately, the matter has not reached the worst level yet, and it is also a blessing that this letter came in time. If it were seven or eight days later, it would probably be that many people in the city would have been killed or injured, and even the difficulty of capturing Hanoi City would have been doubled.

However, it is not difficult to see from the letter that there are already many generals in the city who surrender in this matter, and what they lack is just an opportunity, and the best time is when Pan Feng sieges the city!

Speaking of which, some killing weapons that craftsmen made during this period have been made, but now there are not many, and they cannot attack the city with a crushing momentum.

Thinking of this, Pan Feng didn't care that it was late at night and asked his personal guards to call all the generals in the camp over. Even Guo Jia asked Pan Feng to take it out of the bed.

The siege battle is about to break out!

......

The next day, when it was dawn, the Jizhou camp began to boil.

It took nearly a month since the expedition. Except for Xu Rong, the Jizhou Army won a big victory at the border between the two borders, no other battle has happened, which has long been ready to fight with the soldiers.

Now that Pan Feng was about to attack Hanoi City, the soldiers were suddenly excited.

Making achievements is now!

With the command of the generals of various departments, the army marched forward to Hanoi City with great pride.

The news of the Jizhou army's operation was not hidden at all. When Zhang Yan learned that the Jizhou army was coming to attack the city, Zhang Yan immediately came to the city wall.

From afar, Zhang Yan saw a dark and erectile swathe outside of the city.

"If you inform me, everyone will cheer me up. You must not give the Jizhou army an opportunity. In addition, send people to the city to speed up patrols. Once a suspicious person is found, you will be killed on the spot!" Zhang Yan said with a cold face.

Zhang Yan has been feeling uneasy since yesterday, but he couldn't find out where the uneasiness was. As a result, he heard Pan Feng coming early this morning, and Zhang Yan didn't care about it anymore and could only make arrangements as safely as possible, at least in this way, he could be prepared when encountering a crisis.

After these two days of robbery, Zhang Yan believed that the soldiers of the Heishan Army were already united. At least the hearts of the soldiers in the city were all towards him at this moment, and the morale of the soldiers was much higher than usual. In this case, it should not be difficult to resist Pan Feng's attack!

The only thing that made Zhang Yan feel a pity was that the equipment they stolen was only enough for a small group of soldiers' equipment, and more iron armors needed to be built and repaired by craftsmen in the city before they could be used. In this case, it would probably take some time to equip the estimated 20,000 people.

But even so, Zhang Yan's confidence was more sufficient than before.

However, Zhang Yan's confidence was halfway through the siege equipment brought by Pan Feng.

The army had already opened near the wall of Hanoi City. Although Zhang Yan stood on the city, he could not see the faces of the generals in front of the army, but he could clearly see the huge creatures slowly advancing behind the army.

Zhang Yan has never read much. Some of the familiar military tactics and training methods that are known to him are learned from others, and some are understood by him. But looking at all Zhang Yan's experiences, he cannot find any information that matches the big guys brought by the Jizhou Army!

This made Zhang Yan very uneasy.

The unknown is the deadliest.

At this moment, after seeing those big guys, not only Zhang Yan's heart sank to the bottom of the valley, but also some generals on the city also showed fear.

They didn't know what Zhang Yan didn't know.

It is hard to imagine what role those equipment that are taller than the city wall will play when siegeing the city. You must know that the Black Mountain Army has only had nearly a hundred crossbows so far. This is all the long-range means of the Black Mountain Army. But can the weak arrows really work against the giants?

No one dares to guarantee this.

Amid the worrying gaze of the Black Mountain Army, the Jizhou Army led by Pan Feng finally came to the city.

"Listen to the people in the city, my general said, Zhang Yan took the initiative to provoke first and indulge the plunder later, and his crimes should be punished, but you are just obedient and you can do whatever you want. As long as you surrender, you can stay alive. If you follow Zhang Yan to resist stubbornly, the day when the city is broken will be when you wait for the head to land!" A young general took advantage of the gap in the army's rectification and shouted over and over under the city.

The Black Mountain Army on the city was still a little turbulent when they heard this. After all, Sun Qing and Wang Dang had said before that Zhang Yan took the initiative to provoke Pan Feng. Now that Pan Feng is here, they are going to suffer with Zhang Yan.

Of course, some people were in aroused by the robbery two days ago. In addition, Zhang Yan had just sent them weapons, and these people sneered at the shouting below, and some even laughed at the spot.

There were still commotions in the city, but they were within the range Zhang Yan could bear. He saw the soldiers with disdain and the soldiers with dodging eyes. But these people were gone. King Sun Qing was panicked and unbelievable at that time.

Obviously, his decision a few days ago was very correct!

"Listen to the people below, go back and tell Pan Feng that my Heishan Army didn't want to cause trouble, but since you came to the door, we are not afraid of trouble. Those who are brave enough to let the horses come over. I want to see if you have the ability to get this city wall!" Zhang Yan's words were full of energy, which made the soldiers around him feel much more at ease.

A general is a brave soldier.

Zhang Yan's response made the Black Mountain Army's back straighten. At least from now on, the soldiers will no longer be affected by one or two words from the Jizhou Army before they see blood.

The young general under the city cursed a few more words and then beat the horse back to the formation.

At this time, the basic disputes before the war were over. No matter how much impact the young general had on the Black Mountain Army on the city, it could not change the offensive plan of Pan Feng's army.

In the formation, even though Guo Jia and others had seen the killing weapon that Pan Feng ordered people to make a few days ago, they still couldn't help but look back frequently and set their eyes on the slow-moving big guy.

"I don't know how Zihe's head is, but he can actually transform the catapult into this shape. Although the siege is a bit hasty, it's almost certain to have these big guys." Guo Jia couldn't help but say.

Pan Feng, who was beside him, laughed and said, "I feel relieved if I have the words of filial piety."

In fact, when Pan Feng was in Hanoi, he was thinking about something. Zhang Yan from Hanoi used more than 100,000 troops and had the advantage of the city wall. How could the Jizhou army win the city garrisoned by the Black Mountain Army with the minimum casualties?

When Pan Feng thought about this, he thought of the trenchers that were found in the Spring and Autumn Period.

In later generations, the catapult was a powerful weapon for siege. Its main function was not to kill the enemy, but to destroy the city walls and attack morale, and to minimize the advantages of the defending city side to increase the chance of success of the siege.

Based on the memory in his mind and the physics knowledge he learned, Pan Feng finally transformed the catapult into the appearance of the Huihuan in the Song and Yuan dynasties, and the effect directly shocked Guo Jia and others after the trial cast.
