Chapter 319 of the main text of the Ming Dynasty, the landmines were found at the Wuguan city in Weining. After Qin Chuan saw some people in the Jiannu formation with iron picks and iron rods from the telescope, he knew what Huang Taiji wanted to do.

Poaching.

Some people like to use this method when siegeing cities. For example, Li Hongji, who likes to poach the city, dig the bottom of the city wall like a hornet's nest, and then tie the pillars with thick ropes, allowing tens of thousands of bandits to break the pillars, and then the city wall collapses.

Huang Taiji should have wanted to dig out the two artillery towers, let his men rush in and occupy the artillery tower, seize the firearms inside, and then attack the city wall through the overpass of the artillery tower.

The idea was good, but he didn't know the existence of reinforced concrete, nor did he know that it was harder than stone.

"When the opponent enters the range, you will fire freely."

Qin Chuan put down his telescope and explained to the artillery next to him.

"yes."

The order was passed down very quickly.

When Jiannu entered two miles away, the twenty-two red-clothed generals also opened fire, and the shells covering Jiannu formation became dense.

Jiannu's scattered troops could not avoid casualties, but could only avoid being plowed out by artillery shells.

Moreover, ordinary large shields and shield cars could not stop the shells of General Tianwei's cannon and General Red-clothed cannons. Especially after entering the two-mile range, the shells larger than fists of General Tianwei's cannons can easily break wooden boards with a thickness of less than three inches.

Before entering a mile, three shields were about to be destroyed by large shields on all sides. After several powerful shells smashed through the baffle, they still penetrated into the dense crowd of Jiannu behind and plowed out bloody paths.

But these Jiannu did not retreat, and slowly moved forward with the shouts and encouragement of many generals.

In the Jiannu rear formation, Huang Taiji frowned and looked at the cannons that spit out flames from time to time,

The Qin surnamed had more artillery numbers than he expected, and they were all powerful red cannons.

I don't know how these cannons were made.

If he develops for a few years, when he owns hundreds or even hundreds of cannons, he may not be able to do anything to him.

"Let the Warriors stretch the front and speed up the advancement, and be sure to take down the two enemy platforms before dark."

"twitter."

After Huang Taiji's order was passed down, the ten Niulu 2,500 battle soldiers and the five hundred Wu Zhenchao Ha soldiers continued to lengthen the front line and accelerated the advancement speed.

The purpose of lengthening the front is to reduce the depth damage caused by the opponent's artillery.

However, lengthening the front line and straggling formations also made the minefields they covered larger and wider.

In other words, their chances of stepping on mines will increase significantly.

Except for the city wall in the north of Ningwu Pass, except for the straight road directly in front of the city gate, bombs, or landmines are buried in other places.

There are 300 pieces in total, and they are irregularly distributed in areas one mile long and wide outside the city wall.

After speeding up the advancement, Jiannu quickly entered the minefield and stepped in horizontally in a straight line.

The fastest one was a shield chariot covering more than a dozen dead soldiers, rushing towards the enemy platform on the left, and they were going to dig the corner of the enemy platform.

A dead soldier who was pushing a cart felt like he had stepped on something strange, like a small wooden board, and a sound of clicking came from his feet, followed by a "cry" sound of gunpowder.

The dead soldier subconsciously looked at his feet.

Then, he saw the soil under his feet suddenly explode.

With a loud "boom", the dead soldier flew into the sky before he could react.

More than a dozen dead soldiers beside him were either lifted away or shot into sieve by iron beads shot around. After trembling, they collapsed to the ground.

None of the dozen dead soldiers were spared.

The shield car was blown away completely,

"What's going on?"

Huang Taiji frowned and looked in the direction of the explosion in surprise.

"Report to the Khan..."

A general next to him had just opened his mouth, and a loud bang suddenly came from the front.

Before the sound passed, there was a loud noise at the other end of the front, and then, the entire front line was rumbling like a sudden lightning strike.

Accompanied by the roar, there were broken finger wrecks that were blown away everywhere, with extremely shrill screams and howlings.

The entire Jiannu Long Formation, as if it was baptized by heavenly disasters, was blown up to pieces, with corpses and wounded soldiers screaming and rolling, as if they were hell on earth.

"Blasting cannons is bombing cannons!"

The Niuluzhang Jingwang Shixuan from Wuzhenchao's camp was the first to recognize what it was.

Huang Taiji, who had already turned pale, quickly shouted: "Retreat, withdraw your troops! Let all the warriors come back, hurry up!"

In fact, there is no need for him to shout, the surviving Jiannu would run back by himself. The sudden explosion from the ground exploded and their souls were blown away. They just fled back with instinct, trying to escape a way out.

During the escape, several more bombs were detonated, leaving a group of Jiannu who were running around in scattered places.

There were 2,500 war soldiers, 500 Wu Zhenshao, with a total of 3,000 troops, and only about 1,000 people escaped.

The remaining two thousand people were either killed or injured, and were left on the battlefield.

Suddenly there were cheers at the head of Ningwu Pass. After the Guandi army guarding the city came back to their senses from the initial shock, they burst into thunderous cheers.

Most of them saw the power of the bombing for the first time, but they did not expect that the fierce Jiannu were blown up in such a way.

Even Qin Chuan was shocked himself. It might be nothing if a mine exploded. When dozens of mines exploded like firecrackers, even he was shocked.

That is a mine filled with four kilograms of black gunpowder. Even if the power of black gunpowder is limited, the power of such a large dose of explosion is not small at all.

You can make more of this stuff in the future.

"What should we do if Jiannu drove the people to stomp the bombing guns?"

Just as he was very excited, Li Dingliang, who was beside him, suddenly came over and asked in a low voice in Qin Chuan's ear.

Qin Chuan was suddenly shocked, and the expression on his face instantly frozen.

He was just thinking about how to blow Jiannu to death, but why didn't he think of this problem?

Luo Daniu also mentioned that when they attacked Wanyan Yechen's army, the other party had pulled thousands of people out to attack their military formation.

It seems that Jiannu Wan can do such a tragic thing.

"Where did Jiannu place those people?" Qin Chuan asked subconsciously after coming back to his senses.

"In Yangfangkou, the money, grain, cattle, sheep, mules and horses that Jiannu robbed were also there. According to the news from Zhao Wu, only about two thousand Jiannu were guarding there."

"Can Liao Sanqin pass?"

"I can't get through. There is only one way to Yangfangkou. Now there are Jiannu's horse exploration everywhere. Not to mention more than a thousand cavalrymen, even if Zhao Wu's night is not collected, he can't get through."

Qin Chuan frowned and looked at the Huang Taiji Army outside the city.

"Go and prepare some iron-packed shields, it's thicker. It's getting late now. When Jiannu goes to Yangfangkou to escort the people over, it will be dark. At that time, the troops will be sent out to clear mines and dig back the bombardment."

"But... the boss, isn't this too dangerous?"

"Try it, if it doesn't work, forget it."

"good."

...

In the Jiannu army, after hearing the casualties reported by his subordinates, Huang Taiji's face became even more ugly.

There were 2,500 war soldiers, less than 900 people fled back, and 500 Wu Zhenchao, and less than 300 people came back alive.

He had never fought such a cowardly battle in his life, and had not even touched the other party's hair, and he had suffered such heavy casualties.

"Hmph! Qin Chuan, since you dare to use such a vicious firearm, don't blame Ben Khan for being unkind and righteous."

"Come on, go to Yangfangkou to harbor 10,000 Han prisoners."
