Blackwood Cliff.

On the top of the Chaoyang Mountain to watch the sunrise, Dongfang Sheng stood here watching the sunset.

His hands were clasped behind his back, and his eyes were full of confusion.

Not far away, Dongfang Bubai was slowly walking towards him. Ever since he returned to Heimuya from Fuzhou, Brother Sheng would stay here for an hour every evening, and would not go back until dusk ended and night fell. She had

Asked several times about the reason, Dongfang Sheng always shook his head and smiled slightly.

Brother Sheng has something on his mind! Even her sister doesn't want to tell him.

The golden light gradually faded, Dongfang Sheng turned around and saw Dongfang Bubai in the distance.

Dongfang Bubai said: "There is news from the fire room. Old Wu asked you to go and have a look. He has already made the first mold barrel for the gun barrel you mentioned."

The confused Dongfang Sheng, after hearing the news, relaxed his brows, glanced at Dongfang Bubai, and then hurriedly ran down the mountain, Dongfang Bubai followed leisurely behind.

The fire house was built in a hidden valley to the west of Heimu Cliff. On the way back from Fujian, Dongfang Sheng met a blacksmith who had fled from the Western Regions, that is, Lao Wu. After learning that Lao Wu would

After making the Damascus sword, Dongfang Sheng's head was buzzing and he tried various methods to finally keep Lao Wu.

A blacksmith who can make Damascus swords, others don't know the power of it, but Dongfang Sheng, who is a time traveler, knows it very well.

In the Han Dynasty, many blacksmiths who could make Damascus swords appeared in the late Han Dynasty, but they never appeared in the Central Plains again after the late Han Dynasty.

Don't underestimate this Damascus knife. What Dongfang Sheng needs is not this knife, but the craftsmanship of this crafting process, which is called tempering!

This is a super killer, a process that changes the world. After the tempering process, the inner structure of the steel undergoes a huge change. After this change, the steel is very tough and has a new name.

, called Ma Gang!

Cold weapons made of hemp steel are full of toughness. They are among the best treasures, but this is still a bit wasteful, because they can be used to make gun barrels!

If a gun barrel is made of ordinary steel, with the explosive power of gunpowder, the entire barrel will explode or even burst after a few shots. The reason is insufficient toughness, and hemp steel just makes up for this shortcoming. In modern firearms,

Most guns are made of hemp steel, especially sniper rifles.

Ma Gang, this is an epoch-making thing. After knowing that Old Wu could make Ma Gang, Dongfang Sheng had a very crazy idea in his heart, that is, to make a gun!

Guns seem to be very complicated, but in fact, manufacturing is relatively simple. The most important problem is the technical barrier. This restriction is too great. However, the emergence of Ma Gang has caused this technical barrier to collapse in half in an instant.

The other half is gunpowder!

Unfortunately, as a traveler, the formula of black gunpowder is too simple, mononitrate, disulfide and charcoal. The ratio is 4:1.

Not only that, Dongfang Sheng also knew the formula of smokeless gunpowder.

In fact, black powder was no longer a technical barrier in ancient times. The gunpowder of the Ming Dynasty was close to the concept of 4:1, but it was not that accurate yet.

As for smokeless gunpowder, charcoal, which accounts for 15% of the black gunpowder, is replaced with fibrous cotton. However, the extraction and preservation of fibrous cotton requires technical requirements, temperature, and humidity that are too high to be directly processed at present.

come out.

In ancient times, there was a very critical issue in making guns, which was the concept. The ancients did not have the thinking of modern people, nor did they know the power of modern weapons. The prototype of a gun was a musket, but the reloading speed was too slow.

, causing guns to become disposable items on the battlefield. For this reason, the ancients did not pay special attention to the research on firearms. They specialized in research.

They don't have this concept, but Dongfang Sheng does. When I was bedridden in the past, I read a lot of books on various aspects, and I had a relatively clear understanding of the structure of guns.

When he first traveled to the world of Xiaoao Jianghu, Dongfang Sheng once thought about making firearms, but due to the barriers of steel, Dongfang Sheng gave up the idea. However, after meeting Lao Wu, he decided to put this crazy idea to death.

Actions.

After taking Lao Wu into the Sun and Moon God Sect, Dongfang Sheng ordered the followers of the Dark Dragon Hall to secretly search for various firearms craftsmen in various states. They used various methods to find more than 20 firearms craftsmen with their families.

Craftsmen. Build a fire house in a hidden valley to the west of Blackwood Cliff and place these people there.

The periphery of the fire room is protected by three layers of famous sentries inside and outside the Dark Dragon Hall. At the same time, this place is listed as the highest secret of the Sun and Moon God Sect, and only the leader can know it.

Guns became relatively simple once they had the concept. After the firehouse was established, Dongfang Sheng gave Lao Wu a task, which was to make a gun barrel, not a fake barrel, but a real rifled barrel.

Rifling, this is another revolution that changes the world. The emergence of rifling has improved the range and accuracy of guns by many concepts. Pulling out beautiful rifling in a small barrel is nothing more than a dream with ancient technology, and

It is a technical barrier, but facing this technical barrier, Dongfang Sheng has a cheating method.

Instead of pulling, use carving!

Beat two wrought iron rods and grind them with garnet to make guide rails for a simple machine tool. Then make a bronze rod the size of a gun barrel, carve rifling on the surface, place it on a simple workbench, and pour it with water.

The method is to pour molten steel around the bronze rod, and then cut off both ends to form the prototype of the barrel. In this way, the outer layer is a steel pipe, and the bronze rod is stuck inside. The way to turn decay into magic is to use fire.

Bronze and steel have different melting points. When the temperature rises to 1,200 degrees, the bronze will fuse into copper water, and the steel pipe will come out, forming the blank of the gun barrel.

After the blank of the barrel comes out, the subsequent process is relatively simple. At this time, the barrel is not very hard, which is convenient for grinding and drawing. Then the barrel is pressure tested and the water tank is used. The subsequent tempering is not required.

Dongfang Shengjiao, this is Lao Wu's special skill.

After Dongfang Sheng told Lao Wu the method he came up with, Lao Wu has been handling the practical process. Now nearly a month has passed and it has finally been worked out. Dongfang Sheng is in ecstasy because the hot weapon will be released ahead of schedule.

Already?

When Dongfang Shengfeng rushed to the fire room, a group of craftsmen were surrounding Old Wu. They looked at the dark and shiny gun barrel in Old Wu's hand and marveled at its exquisiteness.

When Lao Wu and other craftsmen saw Dongfang Sheng coming, they handed the barrel of the gun to Dongfang Sheng and asked him to test it. When Dongfang Sheng saw the barrel in his hand, which was almost the same as the gun barrel of later generations, his face changed.

Full of ecstasy, the surface of the entire barrel was polished very smooth. He lifted it high and saw three beautiful rifling lines inside through the sunlight, almost like a modern mechanical carving.

The biggest problem, the barrel, has finally been solved!

Now that the barrel is complete, how can there be no gun body?

At this time, a firearms craftsman handed over a simple version of the gun body. This gun body was slightly improved on the matchlock gun of the Ming Dynasty, and it was just for show.

When the barrel and body of the gun merged into one, Dongfang Bubai walked in. After Dongfang Sheng played with it in his hand, he threw him to Dongfang Bubai. After Dongfang Bubai looked at it carefully, he said

The question in his mind was: "Brother Sheng, is this the musket you have been dreaming about these days? Is it no different from me shooting a matchlock?"

Dongfang Sheng just smiled and did not explain. Even the firearms craftsman could not digest this thing for a while, let alone her.

So Dongfang Sheng just gave Dongfang Bubai an expression that you will know when the time comes.

"Old Wu, thank you for your hard work. I will ask someone to give you three hundred taels of silver as a reward later. In addition, I will give you another day off and have a good rest!"

Dongfang Sheng threw the gun to one of the firearms craftsmen, and then asked one of the more experienced craftsmen among the firearms craftsmen: "How is the research going on with the cannon?"

Crackers are a kind of firecracker that was often played in modern times when children were young. Don't underestimate this kind of thing, because it can be used as a primer for bullets.

Dongfang Sheng had told them the formula of black powder a long time ago, and they successfully came up with the formula. A bullet consists of a cartridge case, a warhead, gunpowder and a primer. This is a modern bullet. For the matchlock gun of the Ming Dynasty, a bullet

The firing frequency of a bullet is too low. If this were to happen on the battlefield, it would most likely lead to close combat after a few bullets.

The most challenging thing about bullets is the primer. Modern primers are something Dongfang Sheng doesn’t expect or cannot ask for. They can only use a dropped cannon as a primer. Once the primer is ready, a bullet will be successfully produced.

Dongfang Sheng originally thought that this research would take some time, but when the craftsman surnamed Wang put a smashed cannon in front of Dongfang Sheng, Dongfang Sheng's heart was pounding, and it took a long time to calm down the excitement in his heart.

, carefully took the small firecracker, and when the firecracker exploded in the yard, Dongfang Sheng knew that the world was about to change!

Snap...

The explosion of the cannon frightened Dongfang Bubai. She did not expect that the gunpowder could be detonated without fire. After a while, she squatted on the ground, picked up the remaining shell of the cannon, and held it in her hands.

There was a very confused look on his face.

"Very good, very good. Everyone in the fire room will be rewarded with two hundred taels of silver and a day off!"

The progress of the fire house was beyond Dongfang Sheng's expectations. Now, he had to do another important thing as soon as possible. After coming out of the fire house, Dongfang Sheng and Dongfang Bubai walked on the path in the forest.

"Sister..." Dongfang Sheng paused, but he couldn't pronounce the word "sister". After a while, he said: "I need a group of people, not many, three hundred is enough, among these three hundred people

, I will ask Tong Che to find some adult orphans outside to fill the gap.

Half, and the remaining half, I will choose among the members of the church. However, what I need is someone with a clean life experience, a clean relationship, and someone who is loyal to you. As for the level of martial arts, it doesn’t matter. I hope sister... help me list one.

A list." (To be continued...)
