The Rise of Ming Dynasty 1646

Chapter 98
While Xu Erlu and others were busy casting cannons, Zhu Linmi got the first rifled flintlock from Lu Ning.

Four elegant spiral lines spiral from the mouth of the gun to the bottom of the barrel, and the grooves are smooth and flat, making it impossible for Zhu Linmi to believe that it was carved by hand by craftsmen.

He immediately asked someone to fetch a bag of freshly made Mini bombs, and took them to the barren beach outside the iron yard to try out the guns.

It was still fixed on the wooden frame first and tested more than ten times, and the rifled gun was very reliable.

Zhu Linmi personally picked up the new gun again, loaded the ammunition, put the butt of the gun on her shoulder, closed her left eye and aimed at the wooden target in the distance.

When the red heart on the wooden target appeared between the front sight and the rear sight, he decisively pulled the trigger.With a loud noise, the one-foot-wide wooden target more than a hundred steps away was instantly punched out with a hole the size of a bowl.

He fired several shots in succession.It is completely different from the situation of the lead bullets flying randomly in the previous smoothbore blunderbuss. The rifled blunderbuss simply refers to where to hit, and it has a vague feeling of a rifle of later generations.

Lu Ning also tried firing a few blunderbusses, and was obviously very surprised, "Although this blunderbuss looks no different from ordinary flintlock blunderbusses, it has a very high aim and shoots extremely far. It's like a completely new one!"

Zhu Linmei nodded, "This blunderbuss is completely different from the flintlock blunderbuss, so we should change its name to show the difference." He thought for a while, "Let's call it 'Type II Jaeger blunderbuss'."

It was the second year of Longwu, and it was named "Type II", which is convenient and easy to remember, and also has some commemorative significance.

"This gun barrel is very well processed," he patted Lu Ning on the shoulder and said, "Just according to this standard, draw the rifling at full speed!"

"Little man obeys."

It was not until more than 20 days later that the clay fan of the largest 24-pound cannon was finally dried and fired.

Then Xu Erlu led people to use clay to cast an iron fan with two layers of inner and outer layers with a total of ten sections.

The six-foot-high iron formwork weighs more than 4000 kilograms. It took more than a hundred craftsmen to work together and it took half a day to fix these heavy molds.

The casting process was relatively smooth. Recently, the craftsmen have cast a large number of iron cannons, and their hands are quite skilled.Soon, the inner layer of a 24-pound gun was cast.

After the casting is cooled, it is sent to be calcined according to the established procedure.On the other side, Tie Fan has already started preparations for the next casting.

The next day, after the inner layer of the cannon body had been calcined, Zhu Linmi asked craftsmen to saw off a layer of skin at the muzzle.Sure enough, all the way to the center of the casting has been fired into gray iron.

The outer layer is then cast.In fact, this is equivalent to using the inner gun barrel as a part of the iron fan, and putting a circle of outer fan on the outside.Finally, the molten iron is poured between the inner gun barrel and the outer mold, which is exactly the same as the ordinary iron mold casting process.

Song Yingxing was a little worried and said, "Your Highness, will this cast iron melt the inner cannon body?"

Zhu Linmei shook her head and said, "The inner cannon body has been calcined, and the carbon contained in it has been oxidized in large quantities, and the carbon content has become very low. Mr. Song, do you still remember what I told you, the lower the carbon content, the higher the melting point of iron?" .”

Song Yingxing has already memorized the knowledge of carbon steel by heart. After Zhu Linmi said this, he immediately realized, "The newly poured pig iron, that is, high-carbon iron, really can't melt the low-carbon iron in the inner layer."

On the other side, one hundred and thirty or forty craftsmen are working together to pour molten iron into the outer iron form.As the iron fan was gradually filled, the giant cannon weighing nearly [-] kilograms had faintly revealed its majestic figure.

The outer gun barrel gradually cooled and shrunk, and was tightly bound to the inner layer. The huge contraction force squeezed the inner layer extremely densely, and even some very small scars were compacted.

On the city of Nanchang.

Li Lang looked up at the starless night sky. The outside of the city was as dark as an ink vat. This was the opportunity he had been waiting for for a long time.

He waved his hand behind him, and immediately more than 60 people in black, masked and carrying burdens followed.Then the Qing soldiers guarding the city put these people under the city with bamboo baskets and ropes.

These people did not dare to use torches, and each took out a palm-sized lantern, which only illuminated the ground two feet below their feet, and headed towards the Gan River in the dark.

The Ming army had a huge fleet parked there. Originally, Nanchang City could get a little supply from the north along the waterway, but it has now been cut off by it.The city was surrounded by tens of thousands of Ming troops, and people in the city were in panic all day long.

Now the Ganjiang River is in the dry season, and the water level is very low.Li Lang recalled the process of rehearsing hundreds of times in his heart again - approaching the Ming army fleet along the dry river bed while it was dark, scuttling a few ships at the downwind port to block the channel, and then igniting the upper ships with heavy kerosene. The ships in the air, so those hundreds of warships will be burned!
If this operation goes well, it will not only restore the Qing army's water supply line, but also revive the morale of the army in the city.Jin Zongbing said that the imperial court has sent General Zhengnan to pacify the south of the Yangtze River. As long as we can persist for a few more months, the siege of Nanchang will be resolved!

During the day today, the secret agents lurking in the Ming army had already told Li Lang the location of the fleet. With the compass in his hand and the faint light, he saw a large pulsating spot of light on the river from a distance - the Ming army boat. Lights on board!
Li Lang turned around and ordered his subordinates to extinguish the lantern, and walked slowly in the dark night aiming at the light.

The light became more and more obvious, and he could even see the silhouettes of several giant ships as tall as buildings.According to the plan planned in advance, 25 people went to the upper wind to set fire, and the remaining 30 people went to the lower wind to dig the boat.

Everything went extremely smoothly. On a moonless night, the surface of the river was pitch black, and the people on the huge ship parked by the river could not see the shadow of people two feet below.

Li Lang's men quickly dispersed, and one after another took out a cranked rocker drill and started drilling near the waterline.Once the bottom of the ship is drilled through, then use a crowbar to expand the drill hole, put gunpowder in and detonate, these ships will quickly sit on the bottom, blocking the retreat of other ships.

Then his men on the upwind will start setting fire.

But just as he drilled the first hole on the side of the ship, he heard the sound of horseshoes in the distance, turned his head, and saw more than a dozen Ming soldiers holding torches walking along the river.

He was very anxious and hurriedly ordered his men to stop digging the boat and keep quiet, hoping that the patrolling people would leave quickly.

Unexpectedly, the Ming army came straight to the side of the ship by a strange coincidence.

Soon, the team had already reached a distance of more than five zhang from Li Lang, and then saw a figure swaying on the side of the ship with the help of the torch, and shouted, "Who?!" Then they blew the horn.

In an instant, the vicinity of the Ming army fleet became brightly lit, and hundreds of people seemed to emerge from the ground suddenly, holding a torch in one hand and a sword in the other, and began to check the net.

Li Lang and the others were like fleas on a bald man's head, standing still under the firelight, not knowing what to do.

The sound of the horn just now obviously alarmed the sailors on board, and soon someone holding a torch pointed at Li Lang and shouted: "There are thieves destroying the ship!"

Immediately afterwards, dozens of sailors holding bird guns appeared on the deck, and the crackling was a shot.

The Ming army's sampan was also put down quickly, and immediately surrounded Li Lang and the others tightly.

Could it be that some spy leaked the news to the Ming army?Li Lang couldn't figure out why he acted so secretly, as if he was ambushed by the Ming army.
