Chapter 161 Yellow dynamite breaks through the city gate!Internal strife in the Ming army!
Zhang Kejian and others who were watching the battle in the city gate tower did not expect that the enemy could break through the suspension bridge so easily and attack the Moon City Gate.

They all lost their minds for a moment.

After coming back to his senses, Zhang Kejian slapped the battlements angrily, "How can the Li'an Civilian Ministry be so timid in fighting? The enemies have all arrived at the city walls, but the country soldiers haven't fired a single shot!"

Because Yuecheng was too important and Liu Sheng could only attack one side, Zhang Kejian arranged for guerrilla Li Anmin to take charge of Yuecheng.

Wang Chengzeng looked ugly.

Li Anmin was one of the two rural guerrillas in Xiangyang. In theory, he was first under the supervision of him as the prefect, and then under the supervision of Zhang Kejian, the supervisor.

Therefore, he couldn't help but defend the Ministry of Civil Affairs of Li'an: "The enemy has so many red barbarian artillery, and they all use explosive ammunition. The rural soldiers have never seen such a formation, so naturally it is difficult to parry it for a while."

Zhang Kejian was too lazy to pay attention to Wang Chengzeng, and immediately asked someone to send an order with a flag, asking the Li'an Ministry of Civil Affairs to eliminate or drive away the enemies under Yuecheng as soon as possible.

On the other side, Liu Sheng also did not expect that Helian Yue could rush to the bottom of Yuecheng in one wave.

But he reacted quickly.

They decisively dispatched two hundred guards from the Huben camp and one hundred guards from the Jieying camp to escort a pack of explosives to blow up the city gate.

This explosive bag is not big, only a few dozen kilograms, and a soldier can carry it on his back.

In addition to the multi-armor players, the Huben Battalion also uses guns and explosives. Therefore, the specific task of carrying explosive packs on their backs is also the responsibility of the Huben Battalion.

Zhou Xing, who was selected into the Huben Camp in Ruyang and served as the commander, won this opportunity to make meritorious deeds.

He carefully put the backpack containing the explosives on his back.

Tongshi's personal guards also looked nervously.

Can't tolerate them not being nervous.

Because they knew that the explosive bag contained not black gunpowder, but a yellow gunpowder developed by the commander!
As personal guards, when Liu Sheng tested this explosive bag made of yellow gunpowder in Tianmu Mountain, they had seen its power with their own eyes.

Therefore, it is clear that this explosive pack is enough to send dozens of people around to the sky!

"Hurry up!"

The captain in front urged.

"Knife players must protect Zhou Shichang when crossing the bridge!"

At the stone bridge of the moat, it is difficult for Xiangyang City's bows, arrows and muskets to shoot, only artillery can.

But whether it was the artillery on the city wall or the moon city, it was either bombarded by the rebel army artillery and temporarily disabled, or the gunners were killed and injured and could not be used for the moment.

The bows and arrows of the soldiers on Yuecheng could hit the flying bridge.

But first they have to eliminate Helianyue and others under the city.

Under the urging of the order, a few rural soldiers risked their lives and threw down the prepared rolling stones, killing and wounding three or five rebels in one fell swoop.

As for the gold juice and kerosene on the Moon City Wall, almost all of them were blown over by the first two or three rounds of artillery.

Needless to say, it also caused a stench on the city wall, and some kerosene caught fire, injuring many rural soldiers.

There were also rural soldiers who risked their lives to shoot arrows at the rebels who were crossing the flying bridge, but they had little effect and were easily killed by the rebels with matchlock guns and bows and arrows.

In this way, under the cover of his colleagues, Zhou Xing quickly rushed to the city gate carrying an explosive pack.

The soldiers of the first battalion arrived first. Under the command of He Lianyue, they pried open the stone slab at the corner of the city gate and dug out a small pit, which went straight under the city gate.

Zhou Xing felt that this pit was of little use, but it did not dampen the goodwill of the friendly forces.

He deftly took off his backpack, put it into the pit, and then pulled out a lead from inside.

Then he shouted: "Everyone retreat, at least thirty steps away!"

He Lianyue also knew the power of this explosive pack, and immediately led hundreds of soldiers to cover each other and retreated to the stone bridge, leaving only Zhou Xing and a few guards from the Huben camp to protect him.

On the moon city wall, guerrilla Li Anmin finally dared to show his head and take a look at the enemy's situation.

But he looked confused.

"Why did the enemy retreat?"

No one answered Li Anmin's words.

Upstairs at the city gate, Zhang Kejian and others also looked puzzled.

"Could the enemy want to blow up the city gate?" General Liu Guang first guessed.

Although Wang Chengzeng was not familiar with military matters, he did know some common sense.

He heard the words and sneered, "It would take at least five to six hundred kilograms of gunpowder to blow open the Moon City Gate. Which eye did Liu Shen use to see the enemy transporting gunpowder?"

The soldiers in the camp were drunk and causing trouble, which caused too much trouble for the prefect Wang Chengzeng, so he even disliked Liu Guangxian.

Liu Guangxian did not refute, but looked at Yuecheng Gate, feeling uneasy...

In front of the rebel formation, Liu Sheng kept staring at the situation at Yuecheng Gate with a telescope.

Black gunpowder had actually developed almost as fast as modern times in the late Ming Dynasty.

For example, the optimal ratio of saltpeter, sulfur, and charcoal, granulation, etc. have been explored and used for many years.

Even Liu Sheng could only slightly increase its power.

And if you want to rely on black gunpowder to blow open a city gate, it will take at least hundreds or thousands of kilograms to be safe.

If you want to blow up the city wall, you need to follow the example of the Taiping Army, dig a tunnel under the city wall, and bury a coffin of explosives.

However, this tactic takes a long time and is not suitable for all terrains.

A moat like Xiangyang's is really just a river. It is extremely difficult and almost impossible to dig a tunnel through it.

One of Liu Sheng's preparations for a successful surprise attack on Xiangyang was to use local methods to make a small amount of yellow explosives under simple conditions.

This is the most suitable explosive he can produce under the current conditions.

The main component of yellow explosive is picric acid.

This stuff has been used as yellow fuel since it was first discovered.

It took decades for people to realize that it was explosive and could be used as explosives due to an accident.

It is also relatively simple to make. Just mix nitric acid and indigo in a certain proportion to get a yellow substance.

There is also a small amount of pure nitric acid in Liu Sheng's villa, but it is really very small. It is too wasteful to use it to make picric acid.

Liu Sheng's "nitric acid" was made using local methods, and it contained a lot of impurities, but it was still usable.Therefore, the power of his yellow explosive is inferior to that produced by chemical methods.

But it is enough to blow up the city gate with dozens of kilograms.

Because the explosive calorific value of picric acid is 5 times that of black gunpowder, the volume of detonation gas is 2.5 times that of black gunpowder, and the explosion power of the same weight is 90 times that of black gunpowder!
Even with this weakened version of yellow gunpowder, the explosion power is estimated to be more than 50 times that of black gunpowder.

The explosive package used to blow up the Moon Gate weighs 40 kilograms, which is equivalent to 2000 kilograms of black powder!

Under the telescope, Liu Sheng saw that Zhou Xing first asked his companions to retreat, and then he lit the one-meter-long fuse.

In order to ensure the explosion of yellow gunpowder and its stability during transportation, Liu Sheng built a small bag of black gunpowder into the yellow gunpowder - black gunpowder is more likely to be detonated by fire, thereby detonating the bag of yellow gunpowder.

After Zhou Xing lit the fuse, he immediately ran towards the stone bridge.

As for the attack from the city wall, he couldn't care about it.

He wore chain mail, cloth face armor, and an iron helmet. The bows and arrows of the soldiers in the city could not hurt him, unless someone hit him with a blunderbuss or a squatting tiger cannon.

But even if you are hit by enemy gunfire, it is "safer" than staying near the city gate.

Guns are expensive, and the country soldiers are not equipped.

But Zhou Xing was the last one to run away, and he was so conspicuous that not to mention ordinary rural soldiers, even Li Anmin, a guerrilla, wanted to beat him.

"This man is too arrogant. Hurry up and use the Crouching Tiger Cannon to blast him!"

In the previous artillery fire, although the Tiger Crouching Cannon on the Moon City Wall was not damaged much, the gunpowder exploded a lot.

Upon hearing Li Anmin's order, a clever rural soldier quickly found a barrel of gunpowder, filled it with gunpowder and Gongsun bullets, and prepared to fire a shot in the direction of the stone bridge.

However, before he finished loading, he felt a huge earthquake under his feet!
The whole person soared into the sky!
boom! !

A loud noise also spread almost at the same time.

City gate upstairs.

Zhang Kejian, Wang Chengzeng and others saw that this section of the Moon City Wall on the Moon City Gate seemed to have been hit hard from below by a giant beast, and it suddenly arched up!

Then the masonry exploded, shooting everywhere!
The smoke and dust are like huge waves, sweeping in all directions!
Even the city gate tower shook violently.

Wang Cheng was unable to stand steadily for a moment and was knocked to the ground by the shock.

I was so distracted that I forgot to stand up.

Zhang Kejian hugged the city wall tightly, also looking absent-minded, and murmured: "How could this be? When did the enemy transport the gunpowder?"

Liu Guangxian was also shocked by the explosion and found it difficult to understand.

When he saw the smoke and dust dispersed, and the Moon City Gate and a section of the city wall above had been blown down, he reacted and hurriedly shouted: "The enemy is about to invade Moon City! Send troops to support quickly!"

Amidst Liu Guangxian's shouts, the soldiers on the city wall came to their senses one after another and started to move.

They all hesitated in their actions and looked out of the city with fear, obviously fearing the rebels.

On both sides of the city gate tower, there are sloping stairs leading to the moon city wall.

There is also an Wengcheng in the Moon City, with several walls connected to each other.

Four arrow towers were also set up.

Even if the enemy rushes in, they will be attacked from all directions by the defenders.

However, no matter how good the city defense facilities are, they must be guarded.

The soldiers hesitated and moved slowly.

The soldiers on the Moon City Wall, the Weng City Wall, and the city, who were closer to the city gate, were either injured internally by the shock, or their ears were ringing, and they were temporarily deaf; or they were so frightened that they just wanted to stay away from the explosion point.

Although many of the rebels led by He Lianyue were shocked by the power of the yellow explosives, their morale soared when they thought it was their own explosive package.

Helianyue was a brave warrior.

Seeing this, he shouted: "The Moon City has been destroyed! Everyone rush in with me!"

While shouting, he took the lead and rushed across the flying bridge, heading straight for the ruins of the city wall!

The standing army, Huben Camp, and Shengjie Camp guards all followed and charged.

He Lianyue did not stupidly attack the Wengcheng inside the Moon City, but followed the ruins of the collapsed city wall and climbed straight onto the wall!

Because Helianyue was the commander of Shengjie Battalion before, and he also led Shengjie Battalion as an internal response twice and won the battle.

Therefore, the people closest to him at this time were the Baishengjieying guards.

These people are all very agile and can climb the collapsed city wall as if they were walking on flat ground!

Before boarding, someone threw large grenades at the place where the village soldiers gathered!
Boom...
Another series of explosions sounded, and the remaining soldiers were immediately killed and wounded and fled in panic.

The camp soldiers had just come down.

Their morale was already low, and they were resentful about military pay. Seeing how ferocious the rebels were, how could they be willing to fight to the death?
Seeing that the country soldiers were fleeing, they retreated to the city wall first.

For a time, not many of the Ming army fought with the rebels, so they all retreated towards the main city wall in a hurry.

Zhang Kejian finally came to his senses and became furious when he saw this scene.

"Where is the supervising team? Go and kill all the officers who retreated from the battle!"

Zhang Kejian, the supervisor of the army, also had hundreds of servants, who were specially used to supervise the troops.

These servants were very loyal. Upon seeing this, they immediately went up to intercept the defeated troops and wanted to capture the officers among them and behead them.

It would be okay if ordinary officers and soldiers were killed. Most of the officers were veterans. How could they be willing to die in this situation?
Some of the fierce ones started to attack the supervisor's servants directly.

The wretched ones retreated into the crowd and shouted: "It's over! The military supervisor's servants have rebelled!"

Suddenly, the area connecting the main city wall to the moon city wall became even more chaotic.

When Zhang Kejian saw this, he was so angry that he wanted to vomit blood. He stared at Liu Guangxian beside him and said, "You don't care about your soldiers!"

Liu Guangxian was also sweating profusely.

If he could control this situation, could he wait until Zhang Kejian scolded him?
He was about to take his servants to join the supervising team when he heard an explosion coming from behind the city gate tower.

Then there was a sharp and shrill cry: "Enemy attack! There are thieves in the city!"
