This time besieged Bianjing, although Lin Chong very much hoped that the imperial court would get acquainted with each other, and he would take the initiative to make peace with him without attacking the city himself.

But at the same time, Lin Chong also made two preparations to promote peace with war, so he ordered Ling Zhen to lead the Shenji Battalion to Bianjing City in a four-wheeled carriage with the key components of the catapult and the thunderbolt, Liangshan's secret weapon.

Since He Li and Su Yuanjing came the evening before yesterday, they deliberately released their own pigeons, and hesitated between yes and yes.

Lin Chong, General Lu and others had already discussed, and they must teach the imperial court a lesson, so that they would know that our Liangshan Army is a man of his word, and he must not be humiliated, neglected, or fooled.

Just yesterday night, when Lin Chong led the team to raid Gao Yu, all the soldiers of the Shenji Battalion under Ling Zhen's headquarters began to nervously prepare for today's artillery attack with other sergeants.

Because all trebuchets are the core components of the standard version, standardized assembly, and the same weight test bomb has been tested before, under Ling Zhen's order, forty catapults and eighty crockpots crossed arcs in the air, and nearly ninety percent of them accurately landed on the city wall.

Seeing that this was a black clay pot flying up the city, the Song army on the city wall spontaneously dodged, and several officers watched all this with suspicion in their eyes.

They all saw that Liang Shanjun ignited before launching, and knew that this was a gunpowder weapon, but similar to this gunpowder weapon, the imperial court also had it.

For example, thunderbolt fireballs, poisonous smoke fireballs, tribulus fireballs, etc., most of these things rely on arson, poisonous smoke to hurt people, even thunderbolt fireballs and so on mainly rely on sound to frighten people, startling horses, in fact, the lethality is not much.

This is probably the secret weapon of the Liangshan Army, right? It doesn't look like anything special, does Lin Chong want to rely on these "thunderbolt fireballs" to break through Bianjing City?

In the midst of his doubts, the crockpot was about to fall above the head of the defenders of the city or a little further down, and the lead of the carefully calculated test had burned to the charge.

"Boom ......"

"Boom...... Rumble...... Rumble...... Rumble...... Rumble...... Boom ......"

In the deafening explosion, the firelight flickered intensively, and the fireworks instantly covered a short section of the city wall.

"Ah......h

"God......

In the thick smoke and fire, and the roar of the huge explosion, countless Song soldiers screamed and exclaimed, and countless pieces of broken iron and broken tiles were carried by the air waves and burst out in the air at high speed.

There were even a few unlucky ones, and the crockpot just happened to fall next to them and exploded, and immediately the whole person was blown up, his head was blown up, his arms and thighs were blown off, and his limbs and corpses were scattered all over the sky.

Some of those who were a little farther away were not injured by the explosion or the shattered iron or broken tiles, but they were also stunned by the sound of the explosion like a thunderbolt on a sunny day, and their hearts beat wildly.

When they saw that the smoke of gunpowder had gradually dissipated, and there was no one left standing in the area covered by the crockpots, everyone was stupefied when they saw the tragic condition of the corpses and the wounded, and listened to their wails and screams.

"Run!"

"The city is broken, run!"

I don't know which one took the lead, and the Song army defenders on the city wall who were stunned when they watched the smoke gradually disperse reacted immediately, and they all ran desperately to the city, and even because they ran too quickly, they were crowded, and several people were squeezed down when they went down the steps.

In fact, the thunderbolts used by Liang Shanjun this time were all the ones that were originally trial-produced, and the effect was not the best.

Moreover, in this round of launches, although more than a dozen people were directly killed and countless people were injured, there were not many people who were really killed or seriously injured.

Most people were only scratched by pieces of iron and tiles and pierced into their bodies, but they were not fatal or even disabled, but could only be regarded as minor injuries.

As long as these fragments are clamped out, and they are simply medicated and bandaged, they can be immediately put into battle.

However, the morale of the Song army was already quite low, the army had no fighting spirit, and before watching the most favored minister of the official family, Gao Yu and Gao Taiwei, be beheaded by the Liangshan army in public, his heart was shocked and frightened.

At this time, seeing that the secret weapon of the Liangshan army was amazingly powerful and terrifying, and then seeing the tragic situation at the center of the explosion, these defenders immediately lost their morale, collapsed on the whole front, and abandoned the city desperately and fled.

Diametrically opposed to the defenders of the city, the more than 10,000 foot soldiers of the Liangshan army under the city saw that the secret weapon on their side was so powerful, and when they heard the screams and screams of the defenders in the city, they became more and more demoralized, and they all seemed to rush forward.

Seeing that they had rushed to the moat in the blink of an eye like feathered arrows from the string, they quickly put down the boat, and the Liangshan foot soldiers carrying the ladder behind them immediately stepped on the ferry, and within a moment the moat showed a scene of hundreds of boats competing for the current.

Lin Chong and Lu Jiang had already waited to climb a watchtower built by the craftsmen of Liangshan at this time, and looked at the scene of the city from a distance, seeing that it was just a round of "shelling", and the defenders of the city had collapsed, and the two of them also looked at each other and smiled, but then they both shook their heads.

Song Jun really didn't let himself down, he was really vulnerable.

At this time, the tens of thousands of defenders on the city wall had almost run, and the Liangshan army was facing an undefended section of the city wall.

If it weren't for the fear that the world would be in chaos and it would be difficult to clean up, the Liangshan army could even directly attack the inner city and imperial city of Bianjing this time, capture Zhao Ji alive, and reap Zhao Ji's son as the puppet emperor.

Xiang Yuanzhen, who was also on the watchtower, saw the power of the Liangshan army's gunpowder weapons for the first time, and while feeling sad for the uselessness of the Dumen Forbidden Army, he was shocked by the secret weapon of the Liangshan army, and the whole person was a little confused.

"God, the Liang Shan Army has such an amazing killing weapon! Who else in the world can be an adversary? ”

"What's that sound?"

When Zhang Shuye, He Li, and Wang Hao were flying horses to Chenqiaomen, they heard a dense loud sound from the direction of Chenqiaomen, and the mounts of the three of them were startled, so they didn't run away.

The horses neighed, and the three men on the horse were no better, all of them turned pale with horror, and their hearts beat wildly.

The three of them immediately thought that they were afraid that the Liangshan army had already begun to attack the city, but they didn't know what kind of secret the Liangshan army had and how powerful it was.

The three of them were all in their hearts, and they couldn't help but worry about the city defense of Chen Qiaomen.

Straight sissy thief! Didn't Liang Shanjun say big things, could he really break through Bianjing City in one battle?

The group hurriedly accelerated towards the direction of Chen Qiaomen, at first there were many unknown situations, and the people who liked to be lively ran to the northeast with them, but it didn't take long to see more and more people fleeing for their lives, and they all screamed in panic.

"The city is broken, run!"

"The Liangshan army has come in, run away......"

When the people saw it, they hurriedly turned around and ran wildly, and some scoundrels and gangsters were overjoyed when they saw this, and hurriedly took advantage of the chaos to start stealing things and property.

Zhang Shuye and the three of them only brought a dozen guards, and they didn't care about these, but on the one hand, they ordered people to attack and report the news quickly, and on the other hand, they were still escorted by the guards to Chenqiaomen.
