Bang bang, under the Ming army's artillery fire, the bricks and stones in the city walls of Seoul were shattered, and the mountains were shaking and the ground was shaking.

The Ming army was extremely good at using artillery. This was their specialty to build artillery positions on high ground and fire strikes on fixed targets.

(When Tang He attacked the Xia regime in Sichuan, the Xia regime set up artillery on the mountains on both sides of the river to attack the Ming army's warships.)

The Ming Dynasty established the country with martial arts. The old man once said in person that iron cannons are the weapon of the country. There were three permanent artillery bureaus in the capital, and there were more than 9,200 craftsmen who used to make artillery alone.

At this time, the cannons that bombarded the city walls of Seoul were no longer those small-caliber iron cannons, but were large cannons transported through the harbor. According to Zhu Yunqiu's mind, each cannon was almost the size of a nine-pound cannon. The range was as high as twenty miles. The army was called the general cannon, which was invincible.

(The weight of a projectile is more than eight pounds, and the projectile weighs more than eight pounds. That era is considered a heavy artillery)

These heavy artillery were terrifying when fired, and seemed to be trembling when fired. Each artillery was loaded on a four-wheeled cannon cart because of its huge and heavy size.

In addition to these heavy artillery, there are also 100-character bead cannons, flying cloud thunderbolt cannons, blue thunderbolt cannons, poison magic medicine cannons, etc.

Nearly four hundred artillery bombarded the city walls of Seoul on the Triangle Mountain Highlands.

Among them, the one that interested Zhu Yunqi the most was the Thunder Cannon. This cannon weighs only more than 400 kilograms and leans on the ground. The projectiles fired were arc-shaped ballistic. The cannon was fixed in shallow pits with iron nails at the tail.

If this cannon charges two taels of medicine, if it fires an eight-two-level projectile, the muzzle is one inch higher and the range is as high as six miles. If it is filled with three cents of iron sand, the range of three miles will cover within fifty steps.

This is simply the Ming Dynasty version of the shotgun mortar!

In the artillery position, Zhu Yunxiu looked at the cannons and sighed in his heart that he really could not underestimate the wisdom of the ancients! All the creations of later generations were based on the exploration and invention of ancestors.

The caliber is still a little small!

Zhu Yunxi thought to himself that when he returned to the capital, he would go to the artillery bureau to see how he could cast some larger caliber artillery.

Just as I was thinking, there was a thud in the distance, and then a cannon barrel collapsed into the sky and fell heavily.

Your Highness, be careful! Li Jinglong pressed Zhu Yunxi under him in an instant.

While going, I was two miles away from the lonely place! Zhu Yunxiu shook the other party away and walked straight away regardless of the dissuasion of the people around him.

In the artillery position, in the smoke and dust, several Ming soldiers were wailing and were carried down by their robes. An artillery exploded under continuous firing.

The commander of the military doctor will be treated immediately! Zhu Yunxiu shouted loudly, he must be saved!

Looking at the blood-covered gunners, Zhu Yunxiu felt distressed. Gunners are the elites in the army! These gunners are all veterans of the battle.

How many shots did this cannon hit? Fu Youde asked angrily, pulling an officer's neck.

Qiqi...... Qiqi! The officer had a bitter face. Your Highness, the commander, the young man didn't dare to hit the drug. It was only more than three ounces at a time. Who would have thought that it would explode after just a few hits!

Fu Youde had a dark face, remembered the inscription on the cannon, reported it to the military judge, and turned around to find trouble for the work department.

I’m afraid that the casting craftsmen of this cannon will lose their heads. The Ming Dynasty not only had strict military laws, but also had even stricter requirements for military weapons and other objects. The craftsmen of casting cannons must carve their names on the cannons.

Now is not the time to talk about this! As soon as Zhu Yunxiu spoke, the generals quickly bowed their heads and listened respectfully. Where did they dig?

Lan Yu spoke behind her and went, and called Zhang Laogou. Your Highness asked him if he had something to do!

Amid the roaring cannons, people would roar loudly when they spoke.

A moment later, a thin and short man was taken to Zhu Yunxiu.

Are you Zhang Laogou? Where did the tunnel be dug? Zhu Yunhuang asked.

Old Dog Zhang lay on the ground, dared not look up, and went back to Qiansui, digging half of it, and one day, the brothers could dig to the underground of the city wall!

So fast? You are so fooling around! Zhu Yunxiu was a little surprised and spoke.

Seoul is tall and deep, and the Goryeo people are determined to defend the city, so the siege will have to pay a considerable price. So he thought of a way, could he dig tunnels, dig under the city walls of Seoul, and use gunpowder to blow down the city walls of Seoul.

This method was so broken in the Taiping Heavenly Kingdom in later generations. Now Zhu Yunyu has chosen soldiers who are good at digging or have had experience in miners and secretly excavated under the cover of artillery fire.

But unexpectedly, the progress of the excavation exceeded his expectations.

The villain has some courage and dares to deceive Taisun Qiansui! Zhang Laogou kowtowed, the soil in the north is not sticky, and the brothers are hammering down a large area.........

Let's take the orphan to see it! Zhu Yunxiu felt that it would be better to see it.

Afterwards, the group came to the Ming army's position at the foot of the mountain. On the outside, it looked like the Ming army's camp, but in fact there were several tunnels hidden.

A square hole appeared in sight, and the hole was straight and wide, forming a straight hook shape underground, leading to the distance. Both sides of the tunnel were compacted and pushed with wooden squares to prevent landslides.

In the tunnel, countless shirtless soldiers pushed wheelbarrows and drove out of Obito.

Your Highness, you can't go inside! Seeing that Zhu Yunxi was curious about getting in, Li Jinglong and others rushed forward to stop him.

Three such tunnels were dug in total? They were all so fast? Zhu Yunhuang nodded and asked casually.

When you go back to Your Highness, it’s the same. The villain counts the distance. Liu Laosi leads people to dig. We have many people. The brothers in front dig, and the brothers in the back rammed earth on the top of the top of the earth, and they are dug out in three or two days! Zhang Laogou said timidly.

Liu Laosi? What did he do before?

There are really hidden dragons and tigers in the army. Zhu Yunxiu looked at the straight tunnel and asked with a smile.

He used to be a mining player! Zhang Laogou replied.

No wonder! Zhu Yunxiu asked casually, what did you do before?

Zhang Laogou suddenly knelt down and did not dare to speak.

Your Highness asked you what you said, "I'm mute?" Li Jinglong cursed.

Little Man, Little Man used to dig... tomb robber! Old Dog Zhang buried his head in the soil and said in a trembling voice. Later, he was arrested by the government and was exiled to the army!

It's a bargain! Zhu Yunsheng smiled.

It's really cheap. The tomb robbers of the Ming Dynasty ruled that all the tomb robbers were executed without discrimination, and they also had to execute the wife, brothers, etc. of the tomb robbers.

This guy is also very lucky! Lan Yu smiled from the side. When he was captured, he was just in the 21st year of Hongwu's expedition to Mobei. He knew that he would die and shouted in the hall that he could still eat meat if a dog died. Killing him would be like slaughtering things. He still has the strength to be sent to the army and go to the border to kill the Tartars!

As he said that, he smiled again. Unexpectedly, this guy was really a soldier. After several battles, he not only did not die but also erected, but now he is a small flag!

What a fucking talent!

Zhu Yunxiu kicked Zhang Laogou easily, how many graves have you robbed?

The villain couldn't remember it, but when he was caught, the villain dug up the grave of a prince in the previous dynasty! Old Gou dared not not say anything, and the more he spoke, the less he became. The tomb was washed many times, and no good things were stolen!

Do it well! Zhu Yunxiu laughed at this kind of thing and said, "Do it well, if you can blow up the city wall, I will ask you for me after the war and reward you with an official position, which will be considered as a glorious ancestor!

Don't worry, the little one is not good enough, so look for a fatal hole! At the time, the thieves of the first few people in the prince's cemetery were far away from the tomb chamber. The villain immediately clicked on the prince's coffin. When he went down the thieves, it was falling on the head of the coffin, and he began to touch the golden ingots as big as a fist.........

As he said that, Old Dog Zhang was speechless and said he was so sad that he was exposed.

Lan Yu's eyes kept beating and her face turned ashen.

Zhu Yunxiu smiled again, let's continue to do it! After laughing, he turned around and left.

~~~~

Come out from the tunnel and walk into the barracks.

The barracks here belong to the first wave of Cao Zhen's troops who attacked the city after the city wall collapsed.

Zhu Yunxiu walked outside Cao Zhen's tent and felt a little strange. There was not a solemn guard outside, and there was also some blessing, sound on the tent from time to time, and a little fireworks.

What was it done inside? Zhu Yunyu directly opened the curtain and went in.

Cao Zhen, who was kneeling inside, suddenly stood up. He had met His Royal Highness the Grand Prince!

Are you...who is Guan Erye?

Zhu Yunxiu looked closely and found that it was Cao Zhen, the Marquis of Jingchuan, who brought a group of subordinates to worship Guan Erye in the tent.

The folk performing storytellings in the late Yuan Dynasty and early Ming Dynasty were very prosperous, and the stories of the Three Kingdoms were also well-known. Guan Yu was loyal and righteous, and was highly praised by the people and the army for his loyalty and righteousness.

I worship the second master and ask for a good start! Cao Zhen bowed and smiled.

What a good lottery? Zhu Yunsheng sat down and blessed you to get promoted and make money again!

I beg the second master to bless Seoul, don’t surrender again! Cao Zhen said embarrassedly, I followed the old emperor to kill people and fight in a war in my teens. I have not won a hundred or eighty cities, but I have never surrendered to two cities in a row!

This is like, pushing Paijiu, grabbing ten in one hand in a row! You have to pay homage to the second master and get rid of bad luck!
Chapter completed!
