This time, they only relied on their own army to defeat the Wu army and kill hundreds of enemies, which greatly increased the confidence of the Huainan army, so in the next two days of attack and defense, their performance was also more and more skillful, relying on the strong city wall and sufficient bows and arrows to repel the Wu army's offensive three times in a row, but their own casualties were negligible. This also made them more confident, and some people began to propose that they could take the initiative to go out of the city to break the enemy.

Of course, as the chief general of the First Army, Peng Yongzhen has not been arrogant enough to be confused to this extent, even if there are really a few reckless generals who propose to him to fight, he was rejected by him with one sentence: "Stupid!" Do you think you'll be able to break the enemy with just a few wins? There are still 100,000 troops outside the city, how can we easily deal with them? If it were that simple, the Shandong army would have been killed a long time ago, and it would be our turn? ”

As he was talking, there was another drumming sound outside, and it was the enemy army who had once again launched an attack on the north gate of Changshu. Peng Yongzhen immediately put the topic away, and said with a serious expression: "The most important thing now is to guard the north gate, don't think about other things." Let's go, go up and see, what tricks can the thief play today! ”

When he led people to run to the city, intending to order his subordinates to continue the defense according to the arrangements of the previous two days, he found that the expressions of the soldiers were different, and many people looked out with panicked eyes...... What is that? ”

After Peng Yongzhen took advantage of the situation to go outside the city, his face, which was still full of ambition, suddenly turned white, and then he screamed: "It's a thunderbolt!" He immediately knew that something was wrong, and quickly shouted: "Quick, send all the shields!" Archers, give me arrows, and don't let the rebels get near the city! ”

There was a confusion at the north gate for a while, some people hurried down to prepare shields, and a large number of archers leaned forward and continued to throw arrows at the enemy outside the city. However, the Wu army had already figured out the range of the Huainan army's bows and arrows in the siege battle in the past two days, and had been operating outside the ground with an arrow, and at the same time, under the efforts of thousands of soldiers, several quaint catapults had been pushed to a stop two hundred steps away.

This catapult is the thunderbolt in Peng Yongzhen's mouth, and the legend is that it was created by Yuan Shaojun during the Battle of Guandu, and it has been a big killer for nearly a thousand years. Because the stones it projected are extremely lethal, and the boulders fall to the ground like a thunderbolt from the sky, so they also have the title of thunderbolt in the army.

This is the clever plan that Pang Wanchun suddenly came up with in a flash of inspiration to break the city.

He was indeed a little confused before, and he only thought about how to destroy the ice on the city wall and ignored his real purpose of breaking the city, so as long as the entire city wall was destroyed, it didn't matter whether it was covered with ice and snow or gold nuggets. And the next sentence of his subordinates to burn the wall with catapults fired oil made him suddenly wake up, so he had the preparations for the pretended siege of the city a few days ago, but in fact he was sending people to make several large catapults in the rear.

Now, everything has been done, as the catapult drove to the front, and many soldiers were busy for a while, under the order, the net pocket that had fallen behind the catapult suddenly bounced up, and immediately the countless large and small stones that had been placed in it rained straight towards the north gate.

Seeing this scene, hearing the stones flying up with a sharp whistle, the defenders of the city suddenly became even more confused, screaming and avoiding everywhere.

But this time, Wu Jun projected a large number of stones, but only the size of a fist, and a dozen or so thunderbolts threw hundreds or thousands of stones at once, almost covering the entire city, how could they easily dodge?

As the stones fell, screams rang out from all over the city walls, and many soldiers were smashed by the stones falling from the sky, and their heads were broken and their bones and tendons were broken...... Without any preparation, especially without even preparing a shield, the soldiers here carried this stone rain completely with their bodies, and the casualties were really miserable. If it weren't for a few pro-soldiers desperately protecting each other, I'm afraid that even Peng Yongzhen, the main general in the army, would have been injured, but even so, he was so frightened that his face turned pale and he couldn't even speak for a while.

After a while, he reacted and shouted: "Put on your shield and hide in the heel of the wall...... "Only by clinging to the wall for shelter can you withstand this terrible stone rain attack."

Of course, the Wu army outside the city could not just stop, with a ruthless order, wave after wave of stone rain continued to pour down towards the north gate of the city, in just half an hour, they actually threw seven or eight rounds of stones into the city, making the city a mess, and the defenders were killed and wounded by hundreds.

And that's not even the scariest of all. When the enemy's offensive stopped for a while, Peng Yongzhen looked up from behind the wall under the protection of several personal soldiers, and was horrified to find that the inner side of the city wall had been potholed, and many places were cracked. Even on the inside, the outside will only be even more unbearable, and you don't need to look to know that the walls and the ice covering them must have been damaged too much.

Before he could come up with a countermeasure, the thunderbolt suddenly came from outside again, and they were so frightened that they hurriedly found a place to hide again. This time, however, the sound of the roaring stones was louder than before, but there were only a dozen or so sounds of breaking the air.

Before they could comprehend, there was a rumbling sound on the wall, and even the defenders above felt a shock, as if the earth dragon had turned over and was about to collapse the entire wall. It was only at this time that everyone understood that the rebels were bombarding the city wall with boulders.

In fact, after throwing all the small stones that were prepared, Wu Jun threw those collected such as the size of the table top and the grinding plate to the rocks, which immediately caused great damage to the city wall, and from a distance you can see that cracks are constantly generated from the city wall, as long as you come in a few rounds in a row, this small Changshu city wall will be completely destroyed!

Faced with such a situation, the Huainan Army was completely out of options. Putting aside the confusion caused by the large number of sergeant casualties, this tactic of the enemy alone is not something they can deal with. After all, when the manpower is exhausted, whether it is an ordinary bow and arrow, or throwing stones, it has a maximum range, and the enemy just places the thunderbolt outside the range and relies on its own longer range to hit you, that is, it is completely passive to be beaten.

For the current Huainan army, the only way is to send an elite army out of the city to destroy the enemy's stone-throwing carts. But even Pang Wanchun has already taken this into account, there is a team of thousands of people waiting there next to the thunderbolt car, as long as the Song army dares to go out of the city, it will definitely not return!

The emotions of fear and despair spread in an instant, and even Peng Yongzhen, as the main general, had no way at the moment, and could only whisper in his mouth: "It's over, it's really over now......"

Fortunately, the stones prepared by the Wu army had been used up at this time, and they did not continue to bombard the city. And after a few battles with a lot of casualties before, even Pang Wanchun didn't dare to be too aggressive and risky, so he didn't take the opportunity to launch an offensive, but prepared to wait for tomorrow to collect another batch of stones and directly completely break the north wall of Changshu, so that he didn't have to risk his life to attack the city.

It wasn't until they saw that the enemy had no intention of continuing to attack the city, and the brave Huainan army felt a little relieved, but everyone was at a loss, looking at each other, not knowing what to say. After a while, someone said: "Why don't you ask the Shandong army to come and help......"

"It's all like this, even if the gods come, they can't be saved, what's the use of them coming?"

The pessimistic words continued to spread, and the entire army had completely lost confidence, which made Peng Yongzhen more and more anxious in his eyes, but helpless.

Just when the whole army was in fear, a team of men and horses finally hurried over, making Peng Yongxin move, and hurriedly stepped forward to greet him: "Sun Chan, you are here, we ...... The last general is incompetent, this north gate is really going to be unable to hold it......" At this moment, he was so anxious that he regarded himself as a subordinate under the jurisdiction of Peng Xuan.

Sun Tu's face was also very ugly, because he had seen everything here in Beicheng from a distance just now. Seeing that the defenders of the North Gate were so embarrassed that they could only be beaten passively, Sun Tu was really angry and even more lamented for his incompetence.

Although even if they were attacked like this by changing to other gates, the morale of the army would inevitably be shaken and the losses would not be small, but they would not become as helpless as they were. And if someone else were to face such a crisis, they would inevitably fight and send troops and horses to attack the enemy's catapult formation, so as to bite off a piece of the enemy's flesh.

But what about the Huainan Army? Their cowardice really made Sun Tu unbearable.

But he didn't want to blame everyone too much at this time, otherwise it would only make the morale of the army even lower, so he just glanced at them lightly: "The enemy's methods this time are indeed beyond my expectations, but there is always a way to remedy, let's go to the city first to see the situation on the city wall." ”

When he got to the top of the city and saw the messy appearance there and the extent of the damage to the outer city wall, Sun Tu's mood became heavier and heavier. He knew very well that the northern city was already in danger, and maybe tomorrow the Wu army would be able to destroy the entire section of the city wall.

And beside him, Peng Yongzhen once again said the heartfelt words: "Sun Chanzhi, how is this good? ”

"You don't have to panic, isn't my Changshu still falling?" Sun Tu said, squinting again to observe the thunderbolt that had not been withdrawn - this car was very powerful, but there was a problem, it was too heavy, so at this time, it could only stay in place first, guarded by a military horse.

After a pause, he said in a confident voice: "The biggest threat is the catapult outside the city. I'm sure they won't be able to prepare too many of these siege weapons, as long as they destroy them, they will be able to keep the northern city. ”

These words made Peng Yongzhen and the others in a daze, what he said was so easy, but how easy was it to destroy these thunderbolts? But after seeing Sun Tu's determined face, they actually really believed it.

After the incident of blocking the entire north gate with ice, Sun Zhan really convinced the Huainan army!

For a while, countless pairs of eyes fell on Sun Tu, just waiting for him to come up with a countermeasure......
