Li Xin said: "Although the mining city has a radius of more than six miles, similar to a county seat, its shape is not irregular, and there are many corners that can be used, not to mention that the city has no moat, if our department can take advantage of firearms, it can still be won directly."

Long Thirteen didn't say anything, and Li Zhanchun said when he saw this, "Actually, there is another way."

"Oh?"

"Siege Reinforcements"

"What city is around? How can you see that Chen Yongfu will definitely come out?"

"The big boss, in the entire Ruzhou Mansion, only Lushan County has a vassal palace at present, which is where the Luyang County Royal Mansion under the Zhou King branch is located, and it is also one of the palaces that have been in the Zhou King branch for a long time."

"At present, although we are waiting for the rebel army to be surging, there is no record of capturing the city where the palace is located, so if we capture Lushan County, Chen Yongfu will definitely not be able to please him, and he will definitely come to the rescue."

Long 13 nodded, "But at the moment, there are more than 10,000 soldiers in our department, tens of thousands of young and strong, in the newspapers in various places, it is estimated that even the 'support of millions' has come out, and Chen Yongfu has less than 3,000, what is the difference between saving and not saving?"

"If I were Chen Yongfu, I would send a small team of cavalry out to attack and harass a few times, and it would be regarded as sending troops to rescue, and most of them would not necessarily come out."

He Jinlong said: "Great boss, I think it is better to use the acupoint technique used in the water gate of Zhaocheng County last time, first perform it in the lead ore fort closest to us, use a cart with a shed to approach, and then bury gunpowder under the city gate, and finally blow up the city gate."

"There are no officers and soldiers in these three small forts, all of them are gathered young and strong, and after they heard this earth-shattering sound, they thought that we had mastered the skill of Thor, and we didn't need too much fighting."

"Big boss, I have a question, I don't know if to ask."

Long Thirteen smiled and said, "If there is anything you can't ask, just ask!"

He Jinlong nodded, "In the humble opinion of the department, the big boss must have taken a fancy to the population here, tens of thousands of craftsmen and miners, but they are a better source of soldiers than farmers, and they can build blades and armor......

Long Thirteen also nodded, "You're right, if there weren't so many miners here, I wouldn't have bothered to take the Mining City."

"That's right, I'll try it out with the lead mine fort first, if we can lure Chen Yongfu out, it's naturally good, if it can't be drawn, we can do the same in the other two small forts."

"Very good"

Long 13 stood up, "This time, the Xuegong Lead Mine Fort will be implemented by the newly established, and the Fourth Brigade Wu Dading Department will be on guard."

......

Early the next morning, Li Xin arrived at the nearest lead mine fort to them.

The so-called lead mine fort is a town formed in the place where lead ore was mined, where the craftsmen who smelted lead ore, the craftsmen who made lead bullets and lead in the vicinity, and the merchants who bought lead ingots, and the Qinglou liquor store attached to these people.

Then, for security reasons, a walled castle was built on the perimeter.

Due to its proximity to the bluestone mountain, the walls of this lead mine fort are all made of stones, but it is also three zhang high, and a large number of young men can stand on it to guard.

By the way, because this place is closest to the bluestone mountain, it is also a distribution base for lime and stone, and a large number of stonemasons and stone merchants gather.

Thus, it is possible that he built a giant stone gate that was pulled by a winch.

In this way, although this kind of castle is not as tall and strong as the county seat, and it is blessed by a moat, it is not easy to break.

Due to the presence of a large number of stonemasons, it is clear that a large number of stones were prepared on the walls for defense.

However, since Li Xin mentioned the method of acupoint exercises, it is obvious that he also relies on it.

As mentioned earlier, Long Thirteen was extremely concerned about the old, weak, women and children of the old camp under his command, because of the winter march, there were hundreds of newborn babies, and Long Thirteen asked the carpenters under his command to build three hundred special carts when he set off from Huozhou.

At present, Li Xin's ten such carts are pushing towards the west gate of the lead mine fort, which is one of the most special carts.

This cart is pulled by two pack horses, and the carriage is enclosed.

It is about one zhang long and four and a half feet wide, and can carry two thousand catties of supplies, and can also carry six to eight people.

The big car has four wheels, the back two are slightly larger, and the front two are slightly smaller, of course, Long Thirteen has not mastered the technology that the front wheels can be steered, and it is still four wheels that can only drive in one direction.

He built a total of such a big car in Huozhou, which was originally used by women and babies who had just given birth, and it was covered with thick carpets from the Fan family, the Wang family, and the Huang family.

The windows on both sides are pull-out, which can be completely closed and opened for ventilation.

Of course, the main place for it to breathe is close to the groom's ride.

The wheels are made of oak wood and iron, and the strength is much greater than that of ordinary wooden wheels, and the top and wall of the carriage are made of oak planks up to four centimeters thick.

There is also a column in the middle of the top that connects to the bottom, so its strength is extremely high, and Long Thirteen tried it when he was in Huozhou, and it can fully withstand the popular stone attack of the Ming Dynasty at this time without collapsing.

Such a thing is naturally dual-purpose, not only for women and children, but also for wartime.

The west gate of the lead mine fort is about the same as all the county towns of the Ming Dynasty, about two zhang high, about one zhang wide, by two stone gates together, the stone gate is thick enough to score, the back is tied with three iron bolts, the general thieves, bandits want to break through this door, don't think about it.

On the wilderness outside the west gate of the silent, cold and dry lead mine fort, the north wind was blowing, rolling up some dead grass and dust from time to time.

On the cyan city wall, there are all the young people standing inside, looking at their figures, they are also relatively strong, in addition to the commonly used hammers for forging lead and hitting stones, there are also axes, knives and other things, of course, the most is spears.

Ten carts were continuing to approach the west gate, and when they approached, arrows were shot down from time to time, and at this time, the horseman who drove the horse was desperately beating the pack horses, and it didn't take long for the ten carts to come to the west gate!

At this time, many of the pack horses were wounded, and the heavily armed grooms unloaded the ropes and bands from the pack horses under the cover of their shields, allowing them to flee back to their camp on their own.

At this time, since the cart was four-wheeled and would not fall immediately, the soldiers on the cart immediately opened the floor and pushed the cart with manpower to continue towards the west gate.

In the end, the two carts were just stuck at the city gate (the city gate was one zhang wide, and the width of the cart was four and a half feet, which was just stuck at the city gate, and Long Thirteen carefully observed the four cities he had taken, plus Jiaokou Fort, the gate was all one zhang wide without exception)!

At this time, the soldiers piled up and smoothed all the 200 catties of gunpowder loaded on the car, and then pulled a splint down from the roof of the car, so that the gunpowder in the middle was tightly sandwiched between the splint and the bottom plate.

Then he quickly ran from under the bottom plate to another cart, and at this time, the stones smashed down from the city gate tower were one after another, and he could only pass quickly with his shield on his head at the right time.

Then these eight carts were all pushed by manpower and quickly ran towards the rear.

Prior to this, the soldier apparently lit the lead rope attached to the gunpowder.

The eight carts had only walked out of thirty meters at most, and then they heard an earth-shattering loud noise behind them!

There is no suspense, the confined space, the cart tightly stuck in the city gate, four hundred catties of black powder, and the instantaneous thrust generated by the explosion will make the iron gate explode, let alone the stone gate!

The huge momentum can completely destroy the city gate, the city gate tower, and the city wall that is centered on the city gate tower to the left and right!

At the same time, the huge explosion force killed all the dozens of young men hiding behind the stone gate!

The movement caused by four hundred catties of black powder caused the entire castle to tremble violently.

This movement is not something that people can digest in a short period of time at this time.

The entire castle was in utter fear.

At this time, Li Xin led him into the city, and then Li Zhong led the cavalry around the castle to guard against the fleeing personnel.

Without any accidents, Li Xin's easily occupied the lead mine fort!

After occupying this fort, the small strong brigade confiscated all the grain, gold and silver of the rich families in the castle

, and then all the parts were given to the poor households inside, and then dozens of "civil officials" led by Li Xin, supplemented by Xue Zhiheng and Shang Ziyi, began to show up with the soldiers in the City God's Temple in the middle of the fort (at this time, people's spiritual sustenance, no matter how small the castle is).

After some agitation, the recruitment of troops must begin immediately, and the strategy of dividing and dividing is the most efficient way to govern the locals.

For several days, the Xiaoqiang Brigade used the same method to take the iron mine fort and the salt mine fort, and harvested a large number of materials and recruits.

Early in the morning of the fourth day, the army finally arrived near the west gate of the mining city.

Compared with the three small forts, the defense of the mining city is obviously much stricter, not to mention, Chen Yongfu's men also have fire guns, tiger squat cannons, archers, wood rolling stones and other defense facilities.

Therefore, although it is okay to use the method of taking down the small fort, it will definitely pay a certain price.

And because of the female wall, it is completely impossible for the people under the city to suppress the people in the city, unless you build an earthen wall as high as the city wall outside the city.

Such an energy-consuming thing Dragon Thirteen naturally wouldn't do.

He had another way.

When he was in Huozhou and Lingshi County, in addition to this acupoint technique, he also had other secret weapons.

No conscience cannon!

Yes, a conscienceless cannon exactly the same as a certain army in later generations!

A large-caliber mortar about four feet long and two feet in diameter!

The bottom end of the mortar is filled with a large amount of primer, and then a thick wooden board is separated, and about three or so explosive packs are placed on the wooden board, and the explosive packs are connected to the leads.

The key to the mortar is the thick wooden plank, when the primer is ignited, the wooden board will push the explosive bag to fly forward, due to the huge caliber, the thrust generated by the instant ignition of the gunpowder has a cathartic channel, and there is no danger of exploding

In later generations, the conscienceless cannon of a certain army could even be changed to a thin-skinned gasoline barrel, and the one-centimeter-thick mortar cannon made by Long Thirteen people with good iron was naturally no problem.

The mortar is placed diagonally on the ground, and the huge backlash force generated by it when fired is also absorbed by the ground.

So, as long as you adjust the angle and set the distance, you can push the explosives package to a distance of 100 meters!

Of course, it will take time to constantly adjust the angle and position of the mortar cannon, and at this point, the dragon thirteen's musketeers can be put in use, they can fire at the enemy in the city from a distance of 100 meters, and they can cover the mortar gunners to constantly experiment with angles and positions.

An hour later, the three mortars finally adjusted the angle and position, and sent six explosive packs to the west gate of the mining city and the city walls on the left and right sides!

"Boom ......"

There was another loud bang.

And then......

Then the world was quiet.

At this time, the mortar cannon can continue to adjust the position and angle of the city wall to "projectile", and the two familiar carts can be grandly debuted at this time.

"Boom ......."

After the last loud bang, Simon collapsed......

This time, Long Thirteen asked Yuan Zongdi, Bai Wenxuan, Long Xiaoshi, and Long Xiaoju to each bring pikemen and firearms to enter from the two city gates, followed by hundreds of cavalry.

In one day's effort, the Xiaoqiang Brigade took the Mining City after losing one or two hundred people!
