The reason why Zhu Youzhen dared to go out of the city was not completely hot-headed. At least he had one weapon in his hand, a flintlock pistol.

This thing knows very well that as a modern person, he has traveled to ancient times, especially if he has become a target of public criticism, and he can't get mixed up for a day without any self-defense. But now to practice martial arts from the beginning, tie a horse and step down the waist, that is obviously pure nonsense, far water does not quench the thirst of the near.

Therefore, the flintlock pistol that John Tang gave him became his magic weapon to protect his life. Although this thing has to be reloaded after firing once, the first shot is still relatively sudden. Therefore, Zhu Youzhen usually practiced his marksmanship as soon as he had nothing to do, and slowly became more and more accurate.

At this time, seeing Zierharang chasing after him, Zhu Youzhen raised his hand and shot it.

Zilharang has clashed with the Ming army no less than dozens of times, so he naturally knows the power of firearms. Although it has less range than a bow and arrow, and has a very slow firing speed, it can be much more lethal than a bow at close range. Even if you are wearing three layers of armor, within twenty or thirty steps, you can still be pierced by projectiles.

But all he had seen before were bird guns, or arquebuses. This type of gun is fired by lighting the arquebus and then pointing the gun at the enemy. This position lasts for a few seconds before the arquebus ignites into the ammunition compartment, igniting the firing charge and ejecting the projectile.

Therefore, although Zilharang rushed on his horse, he saw the six roads and listened to all directions, especially the birds at the head of the city. As soon as he spotted a bird gun aimed at him, he immediately steered his horse around, like a nimble loach.

As a result, the birdmen could not aim, and all the shots were fired indiscriminately, but they did not hurt a single hair of Zilharan.

But Zilharang could not have imagined that Zhu Youzhen's pistol had no arquebus, so there was no need to raise the gun to aim. The shot came out of nowhere and hit Zilharang's left collarbone. Even though he was wearing thick armor, the shot got in and smashed his collarbone to pieces!

Zilharan screamed in pain, and because of the power of the gunshot, he was knocked off his horse and slammed to the ground.

As soon as the Jurchen cavalry with the white flag saw that the flag owner had been shot and fell from his horse, he immediately howled loudly, and suddenly like a ghost possessed him, he rushed to the gap like crazy!

This is where the Jurchen cavalry is far superior to the Ming army. If the Ming army is wounded or killed, it will immediately be in chaos and collapse without a fight; And if the Jurchens see that the Lord is about to be injured, they will be more distressed than the death of their own father, and they will not care about their own safety at all, and they will definitely kill all the enemy troops and avenge the Lord General.

The Guanning Iron Cavalry was already at a disadvantage due to the lack of people, and the Jurchen cavalry collectively went crazy, so they couldn't resist it even more, and they also retreated to the gap.

At this time, Zhu Youzhen was finally dragged back to the city by Yuan Chonghuan. But at this time, thousands of horses galloping outside the city rushed towards this small gap, and it was too late to block it.

Seeing that the Jurchens were about to rush out of the city with Guan Ning's iron cavalry, someone behind Zhu Youjian suddenly shouted: "It's a man's, rush out with General Ben!" ”

With this shout, hundreds of cavalry Ming troops rushed out of the gap, blocking the way of the Jurchen cavalry. Li Chongyao and her Guanning Iron Cavalry took advantage of this opportunity and hurriedly defeated the city.

It was only at this time that Zhu Youzhen saw clearly that the generals of the Ming army who led the army out were none other than Zu Dashou, He Kegang, Wu Sangui and others who were responsible for defending other city gates.

It turned out that Nurhachi had been focusing on the northern city today, and the defenders on the other three sides were very idle. Zu Dashou and the others had long wanted to transfer to Beicheng to support, but they didn't get Yuan Chonghuan's general order, and they didn't dare to leave their posts without permission.

Until Ningyuan's city wall was knocked down by an iron-wrapped car, and the Jin army was killed to the edge of the city, the earth-shattering shouting had already sent a clear message to Zu Dashou and others: The city is about to be destroyed!

At this time, they didn't care about any general orders, and they all led their cavalry to rush to the north city. Fortunately, they came in time to avoid losing the gap immediately.

But these few hundred of them rushed outside the city and were immediately overwhelmed by the thousands of Houjin troops. Moreover, these Ming troops are too far behind Li Chongyao's Guanning Iron Cavalry, both in terms of combat effectiveness and equipment. If the Guanning Iron Cavalry can be one enemy and two, then these three Ming troops are tied together, and they can't beat a single white-armored soldier.

In just a moment, more than half of the hundreds of Ming troops had been killed and wounded, and Zu Dashou and others were also wounded, and they were gradually forced to retreat to the city by the Jurchens, and their backs were almost attached to the city wall, and they were about to be annihilated by the Houjin army.

And at the gap in the city wall, Tong Yangzhen's infantry army has already swarmed in, and they are about to enter the city!

At this time, Zhu Youzhen and Yuan Chonghuan had already re-ascended to the top of the city. Looking at the tragic battle outside the city, Li Chongyao was so anxious that his eyes turned red, and he said hurriedly: "Zu Dashou, they went out of the city to save me!" No, I have to rush out and save them! ”

Zhu Youzhen hurriedly stopped her, and shouted hoarsely: "You can't go!" If you go, you will die! ”

"I'm going to go!" Li Chongyao also screamed at Zhu Youzhen.

Zhu Youzhen's eyes were also red at this time, and he roared loudly: "I am the prince, I said I can't go, I just can't go!" ”

"Then Zu Dashou, they will all let you die!" Li Chongyao suddenly whimpered, rushed to the battlement and was about to jump down the city!

Zhu Youzhen hurriedly grabbed her and yelled at her: "What are you anxious about!" I have a way to fight off the tartars! Yuan Chonghuan, gather all the powder boxes! ”

Yuan Chonghuan was already in chaos at this time, and muttered: "The enemy has rushed to the edge of the city wall, and the Hongyi cannon can't hit it, what is the use of these gunpowders?" ”

"You're stupid!" Zhu Youzhen grabbed Yuan Chonghuan's neck and almost shouted into his ear: "Plug these powder boxes into the fuse, light them and throw them down!" ”

"Huh? Yes! Aha! Ahahahaha! Yuan Chonghuan was slightly stunned, and suddenly looked up to the sky and laughed wildly!

Zhu Youzhen saw that Yuan Chonghuan couldn't stop laughing, and he was really anxious, and he gave him a slap in the face, and even his own hand felt a faint pain.

Yuan Chonghuan ate this slap, but suddenly came to his senses, and immediately ordered all the soldiers at the head of the city to no longer need to shoot bows and arrows, or shoot with birds, and all go to move the powder box!

The black powder contained in the wooden crate was originally intended to fire the shells inside the Hongyi cannon, not on its own. Because every time a cannonball is fired, it is necessary to fill the gun chamber with a charge, for the sake of convenience, these wooden boxes are not big, and they contain a few catties of gunpowder, and the whole box of gunpowder can be poured into the gun chamber when used, and the amount of medicine can be saved.

Yuan Chonghuan picked up a powder box with his own hands, stuffed the fuse into it, immediately lit the fuse, and threw the powder box far away from the city with all his strength. Although he was born in Wen Jinshi, his strength was really not small, and this throw was thrown more than ten meters away.

At this time, the Ming army under the city had been driven to the city wall, and the place where the box fell was full of crowded Houjinbu cavalry. When these people saw a small wooden box falling from the sky, they didn't know what it was, and they didn't want it to hit their heads, so they dodged to both sides.

But at this moment, the flames on the fuse finally crawled into the box. When the box full of black powder met the open flame, it immediately exploded violently, blowing the wooden box to pieces in the air!

Black powder is one of the four great inventions of ancient China, commonly known as "one sulfur, two nitrate and three charcoal", in fact, its main chemical components are potassium nitrate, sulfur and carbon. When encountering an open flame, potassium nitrate releases oxygen, which makes charcoal and sulfur burn violently, producing a large amount of nitrogen, carbon dioxide and other gases, as well as a large amount of heat, in an instant.

The volume of the gases produced by these reactions can expand by 10,000 times in an instant, and the power of the explosion is no small. After a loud bang, the wooden box certainly disappeared, but the dozens of Houjin troops around it were also knocked down by the air wave. Especially those white-armored soldiers who were next to the explosion point, they were all shocked and bleeding, and their liver and intestines were broken! No matter how thick the iron armor is, it can't withstand the impact of the explosion!

Yuan Chonghuan hit it and yelled excitedly: "Throw it at me!" ”

The Ming army at the head of the city did the same, and immediately lit the fuse with countless powder boxes and threw them down the city. Not only did the enemy army not think of it, but even the Ming army itself could not imagine that the powder box could still be used in this way.

As a result, the Houjin army below will be unlucky. This thing is not like a bow and arrow or a bird's gun, even if it is shot accurately, it can only shoot one person at most. It's not even like a cannonball, the big solid iron bump can only hit one line, and if it is slightly staggered, it will be startled at best.

But these small wooden boxes that fell from the sky were a big explosion, and there was no way to avoid it! All of a sudden, the sound of explosions came and went, more lively than the New Year's cannons, and the Jin army was blown up on their backs, and there were severed arms and stumps that were blown away everywhere!

Especially the Houjin infantry army at the gap in the city wall, it was already very dense, a few powder boxes went down, and after a few loud noises, a big black pit was blown up on the ground! The thick gunpowder smoke rose into the air, and it also carried various parts of the Houjin soldier in the air, and one nose even flew up to the city and smashed on Zhu Youzhen's cheeks!

Zhu Youzhen was overjoyed when he saw this, but he didn't expect that he had an idea and used the gunpowder box as a simple grenade, and he was actually a great success!

He picked up a gunpowder box with great interest, and just wanted to throw one with his own hands to have a good time, Li Chongyao jumped over and snatched the box away, and said coquettishly: "With your little strength, you can't throw it far, what if you blow it up to your own people!" ”

Zhu Youzhen's old face turned red, and he smiled wryly: "Miss, what do you think of my idea?" ”

"I don't have any real skills at all, I can only use these crooked brains!" Li Chongyao refused to give in, but finally couldn't help laughing.

The Houjin army under the city was suddenly hit by a fierce blow from the "square grenade", and finally fell into complete chaos.

Zilharan has been rescued by his men. He saw that in a moment, his white flag soldiers fell down in pieces like cutting leeks, and knew that the general trend was gone, so he had to endure the great pain and tears and shouted: "Withdraw!" Withdraw to the camp! ”
