Instead, Yang He found that with the ingenuity of the Ming people, it was possible to save several shooting links.

For example, soldiers can weigh and load gunpowder and projectiles in advance, pack them one by one with paper or small cloth bags, and use them when they are fighting, without having to calculate the amount of gunpowder.

If this link is done well in advance, then when filling gunpowder, you can save some time.

In addition, Yang He did not understand why the people of the Ming Dynasty did not use machinery to make fire, but used fire ropes.

Yang He thought this because he discovered that Da Ming already had such a technology, and this discovery came when he went to the arsenal to count the gunpowder and found a box containing several mines.

After counting the gunpowder, Yang He carefully studied the mines, and then Yang He found that these mines turned out to be pressure mines, that is, mines that can be detonated when stepped on.

The detonation device of these mines is not complicated, that is, a small piece of flint is fixed at the fuse of the mine, and a rotating steel wheel is placed on the flint, and the steel wheel is driven by a clockwork.

This device is based on the same principle as the wind-up toys used in later generations, which use a knob to tighten the clockwork, and as soon as the knob is released, the clockwork begins to drive the gears, which in turn drive the wheels to make the toy run.

After the mainspring on the mine is tightened, it is connected to a spring-like device and locked, and then the spring is installed under the pressure plate, when there is a heavy object pressed on the pressure plate, the spring shrinks to loosen the clockwork, and then the spring drives the steel wheel to rotate rapidly and rub against the flint to ignite, thereby detonating the mine.

To be honest, Yang He was very surprised when he saw these mines, he didn't expect that the Ming Dynasty would have such technology.

(At the beginning of the Ming Dynasty, mines using mechanical ignition devices appeared in China.) According to the book "Fire Dragon Sutra" written by Jiao Yu in 1413, it contains: "The explosive cannon is cast with pig iron, on an empty stomach, and the medicine is pestle, into a small bamboo tube, and the fire line is pierced inside, and the fire trough is worn with a long line outside. ”

The explosives in this case are mines.

In the middle and late Ming Dynasty, when Qi Jiguang was stationed in Jizhou, he also made a kind of steel wheel fire mine, when the enemy stepped on the motive, the steel wheel rotated and the flint was sharply rubbed and ignited, detonating the mine. ）

It was precisely because Yang He saw that the mines of the Ming Dynasty used this mechanical firing device that he couldn't understand why the ordnance manufacturers of the Ming Dynasty did not use this firing device on firearms.

In Yang He's view, as long as the drum ignition device is modified, it can be installed on the musket.

And as long as this firing device is used on the musket, then it is possible to significantly increase the rate of fire of the soldier.

(Note: Later revelor muskets used this principle, and later, the firing pin fired instead of the revelry, so the flintlock pistol appeared, and gradually replaced the arquebus.) ）

In the same way, if mechanical firing can be used on a firearm, then this firing device can also be used on a gun.

In addition, since the Ming Dynasty can make a cannonball, it can be changed into a cannonball, and if it can make a cannonball, the power of the artillery will be greatly increased.

As long as the Ming army can increase the firing speed and distance of the musket, and then increase the power of the artillery, what is the point of just a prisoner?

Yang He was thinking about it when he suddenly heard someone shouting, "It's coming." ”

Hearing this, Yang He hurriedly walked to the wall and looked ahead, only to see dust in the distance, but he couldn't see the figure clearly, and he didn't know how many people came.

After staring at it for a while, Yang He suddenly had a question in his heart, Jianyu were all well-trained cavalry, how could they be shocked by such a big dust when marching? Don't you want the horseshoe anymore?

Turning his head to see that Heiyunhe was also watching, Yang He hesitated and said: "Shenrong, it doesn't seem to be quite right, I don't think it's the forward troops of Jianyu who are coming." ”

Hei Yunhe nodded, and said in a deep voice: "Those people in front are definitely not Jianyu's forward troops, they should be deserters or civilians, I suspect that these people were driven over by Jianlu." ”

Yang He thought for a moment when he heard this, and then nodded silently.

There is a moat around the perimeter of the Quang Ninh city wall.

The moat is an important facility for the defense of the city in ancient times, and many important cities have moats around the periphery, and people enter and exit the city through the drawbridge, and the drawbridge is erected at the gate of the city.

Drawbridges are usually lowered, and when there is a war, they are pulled up. In this way, if the enemy army wants to attack the city, they must find a way to cross the moat first.

In Liaodong, there are many cities with moats outside the city walls, but there are only three large ones, namely Liaoyang, Shenyang and Guangning, and the moat of Guangning City is nearly 20 meters wide.

A few days ago, Sun Degong rebelled, and cut the rope of the suspension bridge at the east gate of the city and destroyed the city gate, the purpose of which was to allow the Jianyu to drive straight into the city when he entered the city.

However, Sun Degong did not expect that Luo Yi would always bring troops back, and then quickly lead his troops to quell the rebellion, causing Sun Degong's plan to surrender the city to the enemy went bankrupt.

After putting down the rebellion, Luo always repaired the gate, and then replaced the rope and pulled the drawbridge up, so that the moat could once again play the role of holding back the enemy.

Although it is winter and the river is already frozen, the ice is still more than a meter high from the ground. In order to attack the city, the Jianyu had to brave the artillery fire of the defenders, come from the ice, and then climb ashore to get close to the city walls or gates.

Obviously, there is a great price to pay for getting through this route. However, the Jianyu population is small, and the Jianyu will not use this method of forcible siege until the last resort.

The prisoners must have driven the people and prisoners around them, so that the soldiers defending the city could lower the drawbridge, open the gates, and let these people in, so that they could take advantage of the opportunity to enter.

"Let's go, go back to the city gates." Black Cloud Crane waved his hand.

Yang He nodded, and followed the Black Cloud Crane to the city gate.

When Yang He and Hei Yunhe returned to the city gate, the people outside the city were also approaching Quang Ninh City.

As Hei Yunhe expected, these people who came from a distance were indeed ordinary people, numbering about a thousand people, and behind these people were a group of Jianyu cavalry.

When they were still hundreds of meters away from Quang Ninh City, those people suddenly quickened their pace and shouted as they ran:

"Open the gates and let us in!"

"Help us!"

……

Seeing the people flocking in, the soldiers defending the city couldn't help but panic, and one of the officers looked at Heiyunhe and said, "Shenrong, what should I do?" Do you want to open the door and let them in? ”

"Can't open it, once the city gate is opened, the builders behind will rush in, then we are finished." A soldier shouted.

"Jianyu is still far from the city, if we move quickly, we can completely close the city gate before Jianyu rushes over." Another soldier shouted.

Listening to the soldiers' arguments, Black Cloud Crane couldn't help but hesitate as he looked at the people outside the city.

At this moment, Zhang Shun, who had been transferred to garrison before, walked to Yang He's side and whispered. "Brother Yang, tell Shen Rong that you can't open the door, and there are soldiers in those people."

Yang He was surprised when he heard this: "How do you know? ”

Zhang Shun smiled bitterly: "Brother Yang, you see that this is a mountainous area nearby, as long as the people flee into the mountains, the Jianyu cavalry will have nothing to do with them, the people are not stupid, they won't even know this truth."

However, these ordinary people kept running towards Guangning City, obviously restrained by the Jianyu soldiers, otherwise, they would have run away without a trace. ”

Yang He nodded silently when he heard this, Zhang Shun had been a deserter many times, and his experience in escaping was extremely rich, so he could see at a glance that there was a problem here.

Zhang Shun continued: "Jian Yu hangs far behind, just to make us think that this distance is enough for us to open the city gate and let the people into the city." But as soon as we open the gates, the soldiers who are mixed in with the people will occupy the gates, and it will be difficult to close them. ”

Yang He nodded, and immediately pulled Zhang Shun to Hei Yunhe's side, and said what Zhang Shun had just said.

Hearing this, Heiyunhe's heart sank, and he hurriedly looked at the crowd outside.

At this time, the people outside were already close to the moat, and when the black cloud crane saw this, he shouted: "Stop, don't come, otherwise they will all be shot." ”

It's just that the crowd outside is crying for help, where can I hear the sound of the black cloud crane?

Seeing that these people were getting closer and closer to the moat, several people who were running in front had even jumped into the river, and the black cloud crane was in a hurry.

At this moment, a man shouted in a deep voice, "Shoot." ”

"The commander has an order, shoot!" Another shouted loudly.

The soldiers didn't have time to think about it, and immediately opened fire on the crackling outside the city.

The outer edge of the moat is about fifty meters away from the city wall, which is the killing range of the musket, and the crowd outside is so dense that you can hit it even if you close your eyes, only to see that people in the crowd are constantly being shot and falling.

In fact, the lethality of muskets at this time was insufficient, and most of the people who were shot would not die as long as they were not hit by the projectile.

But the crowd outside the city did not expect that the defenders of the city would suddenly shoot, and they couldn't hold their feet at all while running, and the wounded people in front fell, and they were immediately trampled under the feet of the people behind, and their fate was worse than being shot and killed.

Seeing that people kept falling outside the city, and then they were trampled underfoot, and there were miserable cries from the crowd, Yang He slowly closed his eyes, and he couldn't bear to see such a tragic situation again.

But the eyes can not see, but the sound can't be stopped, hearing the cries for help and miserable screams, the muscles of Yang He's face can't help but twitch.

Suddenly, Yang He rushed to the edge of the city and shouted outside the city: "Don't come here again, run to the mountain to the north!" ”

But at this time, the sound of gunshots and screams shook the earth, and Yang He's voice could not be heard by people outside the city at all.

But Yang He's voice could be heard by the soldiers in the city, Zhang Shun reacted the fastest, and immediately shouted loudly outside the city according to Yang He's words, and then more soldiers shouted outside the city.

As more and more people shouted, people outside the city finally heard clearly.

At this time, the people in the back saw the defenders shooting, and they had begun to stop, and the people behind stopped, and the people in front gradually stabilized their figures.

At this time, these people knew that the defenders would not open the city gates, and continued to run towards the city gates, only to suffer more violent blows. Therefore, after hearing the shouts of the defenders of the city, these people couldn't help but look at the mountains to the north.
