Li Zijing smiled slightly and said, "Thanks to the exquisite thoughts of the craftsmen in Shangguo, I didn't expect that the barrel of this gun can exert such power in such a shape."

As he said that, he stared at the muzzle of the musket and looked inside, he could see that the inside of the barrel was not smooth, but had two completely rifled lines. In fact, this musket was indeed something that Li Zijing used to it on weekdays, but the most important gun barrel was replaced with a reamer barrel. However, Li Zijing was shocked and the rifled barrel was just an elimination item.

The United States' pursuit of military technology has always been ahead of this world. After all, with the guidance of Li Mingxun, the time traveler, is particularly obvious in the navy. However, the support for the United States' army equipment is also huge. For example, the United States is the first country in the world to assemble flintlock rifles on a large scale, and has derived the "queuing" line infantry. The flintlock rifle battalion with flintlock rifles and bayonets is already the main force of the United States, and the United States has never relaxed its exploration of higher technology. It is convenient for individual gunpowder weapons, especially for rifled muskets.

The rifled rifle is not a new thing, it has been born for more than two centuries. The recorded spiral rifle firearm, that is, the rifle, was invented as early as 1476. More than 30 years ago, the Danish army had already been assembled in small and medium-sized batches in the army. The long range and high accuracy of the rifle have always attracted the army, but the reason why it cannot be assembled on a large scale is that it has nothing to do with the breakthrough of concepts.

At least in this era, except for the hunting soldiers of a few army, rifled rifles are still just hunting tools for the upper class. Young nobles hit targets or prey a hundred meters away in front of aristocratic girls who do not understand military technology to gain their favor. This is the work of rifled rifles for most of their time.

In fact, the main source of funding for the development of rifled guns in the United States was to meet the hunting needs of the nobles and wealthy merchants in the United States. It was not until the Army officially added the hunting troops that rifled guns were systematically assembled. After learning the news, Li Mingxun directly gave the design concept of the Minnie rifled gun to the Army, hoping to make the Army's technology take a big step forward, but it finally proved that the current processing capability of the United States did not have the practical Minnie rifled guns at all.

Processing rifling is not a technical problem. The rifling machine is not as technically difficult as some textile machinery in the hands of craftsmen. It is even more common to cast sub-caliber Minnie bullets, but the key is how to use the two together.

The technical problem is ultimately precise. The requirement for accuracy of the smoothbore gun is to "can drive out the lead bullet", but this is not the case with the rifled gun. Generally speaking, the gap between the barrel of the smoothbore gun and the lead bullet is about 2.5 mm, while the gap of the rifled gun is 0.13 mm. In the era of hand-made guns and lead bullets, skilled craftsmen can achieve the processing accuracy required by the rifled gun, but the processed products are not military guns, but artworks and toys in the hands of the nobles.

If the rifled gun has an unqualified ammunition, it will bring huge problems. If the rifle is too small, the Minnie bullet will over-expand and stick to the rifle, resulting in a blowout. If the rifle is too large, the lead bullet will break into small pieces in the rifle. After all, the lead bullet in this era is not so qualified. Because in this era, the pre-loading gun must be installed, and the rifle must not be as deep as the guns in later generations. This will easily cause lead hanging. Firearms with severe lead hangings are either unable to be used, or the loading efficiency is very low, and practicality is very poor.

The Minnie rifled rifle trial-made by the United States Army Arsenal was tested, with lead hanging, blowing, and blocking the rifle, and the cost was too high. Assembly was to spend money to play with the lives of soldiers, so it was quickly abandoned. The arsenal began to seek other rifle rifle designs. The first batch assembly was the type of rifle rifle given to Li Zijing. The barrel was directly transformed with the barrel of the smoothbore rifle, and two rifles were added. The lead bullet used was different. There was a layer of deer-skin pellets outside the spherical lead bullet, which made the ammunition slightly larger than the diameter of the barrel and needed to be knocked with a small hammer to load. During the knocking process, the deer-skin pellets were embedded in the rifle, thereby achieving the rotation and air closure of the projectile. The range could reach 400 meters, and there was still considerable accuracy in 150 meters.

This type of rifled rifle has made great progress in accuracy and range compared to smoothbore rifles, but the loading speed is very slow. If there is a mistake in the production of the projectile, the projectile may get stuck in the barrel. Therefore, the army has been dissatisfied. After the trial production of the Minnie rifled rifle, the craftsmen of the arsenal made improvements to this and riveted a section of the "tibia" in the barrel!

The so-called tibia is a dumbbell-shaped steel rod, riveted to the bottom of the barrel, and the bullet used is a sub-caliber conical lead bullet. Because the projectile is smaller than the barrel, it can be loaded quickly. After reaching the bottom, a small hammer is used to hit the iron push rod. Under the action of the steel rod and the push rod, the skirt of the tapered lead bullet is closely combined with the rifle to complete the effects of rotation and air closure. This type of rifled rifle that imitates the later Tuwennan style quickly became the standard for hunters in the United States.

Although the sub-caliber bullets are also used, there is still a huge difference between the Tuwennan and the Minnie style. The Minnie rifled rifle completely relies on processing accuracy and cannot be mass-assembled without the machining capabilities of the 19th century (the Russians did it completely in 1860). The Tuwennan sub-caliber rifled rifle relies more on the personal experience of the gun users. If the lead bullet is thicker, the lead bullet will be less than two hammers, and if the new gun is less than two hammers, the old gun with strong wear and rifle will be twice more, and the old gun with strong wear and rifle will be twice more. That's it.

"Judge, now is not the time to express the excellent equipment. The task assigned to you by Chief Li..." The official servant beside Li Zijing put the mesh gun on and reminded him with a smile.

Li Zijing said: "Don't worry, I will act according to the strategy."

Li Zijing has a lot of relationship with the United States. His father died in the invasion of the Qing army. Li Zijing has always been dissatisfied with the court's attitude of obeying the Qing court. Kim Yunche's exclusion and the continuous party struggles in Korea made him hate him. The real origin was four years ago, an immigration ship from the United States to Yongning Chief Executive District encountered a storm and stranded on Jeju Island. Li Zijing provided food, housing and repaired ships, thus starting in-depth cooperation with the United States and gradually developed into the support of Jeju Island.

After packing up the things in the camp, Li Zijing turned over the horse and dozens of fangs went to Jeju City. Jeju Island is the southernmost territory of North Korea. The island has a pleasant climate, but the soil is not suitable for growing rice. Therefore, it has been ignored for a long time. It was not until the Yuan Dynasty brought Mongolian horses to the island, and Jeju Island became the main horse farm, and it developed slightly here.

By the time of the Japanese invasion in Ionchen, Jeju Island became the front line of the anti-Japanese war, but at its peak, there were only two thousand troops stationed. The population of Jeju Island was not abundant. In fact, until the 21st century, the population of Jeju Island did not exceed 600,000, which was even rarer in this era. The three counties on Jeju Island, Jeju, Dajing County and Jeju County, were the administrative centers, and were equipped with the escort Kim Yoon Che and the judge Li Zijing’s civil and military bureaucratic team, while the other two counties had only county supervisors.

In addition to three cities, there were nine towns, ten water battle stations and dozens of beacon towers, which formed a complete defense system on Jeju Island, but that was the time of the Japanese turmoil. In fact, there were about two thousand soldiers on Jeju Island, and they were still distributed throughout the island. The most concentrated one was Jeju City. At this time, there were about eight hundred people. Of course, in addition to these soldiers, there were also Yi soldiers on the island. They were organized by nobles and wealthy merchants during the war. When the Japanese pirates invaded, these Yi soldiers who defended their hometown performed better than the regular soldiers.

Li Zijing rode a horse to Jeju City and found that Kim Yunche had climbed the city wall. At this time, he was wearing military uniform, wearing a cloak, and carrying a bow bag on his waist. He was standing on the city wall and observing the port. There was already a mess inside and outside the city. The beacon towers and Yantai near the port outside the city kept rising. The officials, untouchables and official slaves living outside the city ran into the city in large bags. There were crying and howling everywhere in the city. On the sea, the Japanese pirates could see more and more clearly. There were six ships, all of which were platy houses, two of which were particularly huge. There were at least four or five hundred people in the six ships.

Kim Yunche looked solemn and said in confusion: "Why did the Japanese turmoil happen? Could it be that something happened in Japan?"

No wonder Kim Yunche was puzzled. Jeju Island has not experienced any situation in nearly half a century. The rare rebellion, except for the local official slaves, the fishermen who were unable to eat enough to cause trouble, were soon put down.

"My Observation envoy, there are quite a few Japanese slaves. I wonder what the rules of the dictatorship are there?" Li Zijing asked in a deep voice.

Kim Yunche glanced at him, as if he was looking at a dead person. He had long wanted to destroy the judge and replace him with his own people. This time the Japanese pirates were seen as an opportunity. When the Japanese pirates attacked, Li Zijing, as the military commander with the highest title of Jeju, was naturally unforgivable.

"Don't worry, judge, I have ordered Cui Zhongjun to lead the elite troops to hide in the mountains and forests north of the port, and send another scout to the nearby towns to recruit garrison troops, and organize rebels in the city. Within three days, there will be two thousand soldiers and horses. Today, we will attack the Japanese pirates halfway and let them know the courage of our eastern country. In three days, we will definitely wipe out all the Japanese slaves and report victory to Hanjing!" Jin Yunche said confidently.

"Will the sir report the Japanese riots to the court?" Li Zijing asked.

Kim Yunche smiled and said, "That's natural. The communication ship has set off half an hour ago. The judge should rest assured that the tribute horse has entered the city this year and cannot miss the national affairs."

Li Zijing sneered in his heart, this guy was completely invisible.

Outside Jeju Port, Kawaharada Hiewe stood on the bow of the ship, stretched his arms, and let the little surname beside him wear armor. This southern barbarian armor has a history of more than 100 years and witnessed the glorious years of Kawaharada's family in Japan. It was still well maintained. The armor was wiped with brilliance. In front of Kawaharada Hiewewe, there were hundreds of strong Japanese samurai. Some of them were chewing food, and most of them were whispering to complain about the weapons in their hands.

This unit is called Kawaharada team, composed of Kawaharada's retainers and the party. In recent years, Kawaharada's Uei was operating bleakly on Yulei Island. First, it accumulated the first pot of gold through the smuggling trade between Japan and North Korea, and then formed its own army. At the beginning, the unit had only a few dozen people and was hired by the Yongning Chief Executive District to participate in the settlement of the Jurchen tribes on Sakhalin Island. It continued to grow in the war. Especially after the resumption of the Shandan trade, Kawaharada's Uei got the opportunity to directly hire Japanese samurai from Hokkien. In the end, the Kawaharada team had a total of 480 people, including 150 Japanese samurai, and the rest were from North Korea and Jurchen divisions.

This time, the Kawaharada team accepted the employment of the commander and came to attack Jeju, but the armor and weapons provided for it were broken, which made the soldiers very dissatisfied.

"Master, why did you let me wear such a ragged dress and lose the reputation of Kawaharada's lineage in vain!" A retainer said dissatisfiedly, holding a large and worn armor.

Kawaharada Eimei said: "This is an order from the commander. Our move is not to conquer cities, but to make the Koreans on Jeju Island think that this is a Japanese invasion. This time, we play the role of Japanese pirates, not conquerors. Japanese pirates will naturally look like Japanese pirates!"

After saying that, Kawaharada's face was covered with paint and made a few unruly moves, which made everyone laugh. However, the retainer asked: "Master, because of the failure of the Supreme People's Republic of China, a battalion of troops is enough to flatten the island. Why do you have to do this more than possible?"

Kawaharada Eimei said: "If the upper country is invading the army, how dare you take action with the cowardice of the young man? The local navy will inevitably retreat and attack in the future and attack the route. When we attack, the young man is not clear and the local help will come. At that time, I will catch it in one go. Wouldn't it be nice? My father once said that the denser the rice, the easier it is to harvest. The upper country's military strategy is roughly the same."

The retainer said, "So that's it!"

Kawaharada Hiroe put on a big armor and waved the heavy combs in his hand, saying, "Although the armor is worse, the deadly guy is good. This combstone gun is several times more powerful than the ones used by our clan, and you can defeat the enemy. Heizaburo, the combstone troops will be commanded by you later!"

Heizaburo bowed and bowed, Kawaharada Hiewe stood up, held up the sword high, and shouted: "You guys, come ashore with me. Anyone who dares to stop will be killed without mercy!"

The Kawaharada team successfully approached the port and went straight to the shore from the dock. When they got to the shore, they formed a formation. In the woods in the north, Cui Mingxiu, the central army, saw this scene and his face changed slightly, saying, "This must be not a Japanese pirate!"

"Sir, these people are murderous and look weird, just like the rumored Japanese pirates, and they will not be wrong." said a veteran.
