We are engaged in scientific research in the ancient martial arts world

After having the experience of making the first revolver, Li Yu became more comfortable making the subsequent ones.

The next day, the two began forging the remaining five revolver parts. As for the bullet's new charging process, Li Yu also told Wang Qingyang in detail the formula and loading method. As for the dozens of craftsmen in the workshop, they also produced a large number of crossbows and sliding bow accessories for Li Yu and the others during this period. As for the last step of cutting and polishing, this can only be completed after Li Yu and the two have finished making all the revolvers.

Three days later, the remaining five revolvers also came out one after another. At the same time, Li Yu and Wang Qingyang also equipped each revolver with 5 rounds of spiritual stone and black powder mixed ammunition. All warheads are made of silver alloy warheads, and the craftsmanship of the cartridge cases has been adjusted accordingly. This time, instead of pure brass cartridge cases, brass alloy cartridge cases were used. Because the kinetic energy and explosive force generated by the mixture of black powder and spiritual stone powder were too strong, the original brass cartridge case was easily deformed after the bullet was fired, causing the cartridge case to get stuck in the magazine and making it difficult to remove. Therefore, Li Yu and Li Yu People then improved the material of the brass cartridge case to increase the hardness of the brass as much as possible without sacrificing the toughness of the brass.

After their testing, the brass alloy cartridge case with improved material has indeed solved the problem of easy jamming. At this point, the manufacturing work of 6 revolvers and 300 rounds of 7.62 mm specially loaded ammunition is completed, which took about a week in total.

Next, the work that Li Yu and the two have to do is really the highlight. They need to cut and polish thousands of pulley parts, dozens of bow arms, and hundreds of core components of the crossbow. Just thinking about this workload made their scalps go numb. As for the manufacturing of the spiral arrows in the new workshop, it is basically nearing completion. Thousands of spiral arrowheads have already been made and polished by craftsmen, and their next task is to make suitable arrow shafts and tail feathers for these arrowheads.

Li Yu had already arranged for Mo Wuhen to purchase the materials for the arrow shaft and tail feathers. There are two types of arrow shafts used in spiral arrows. One is a long arrow shaft used in longbows, and the other is a short arrow shaft specially used for crossbows. Li Yu also designed all these arrow shafts to be detachable, so that arrows can be replaced at any time. Mo Wuhen is currently in charge of the supervision of the new workshop. He will report the progress there to Li Yu alone every day. Therefore, Li Yu is also very relieved about the work progress in the new workshop.

Li Yu's current work only needs to cut and polish all the required parts for crossbows, pulley bows, and that's it. As for the final assembly work, there is no rush. After all, the assembly of crossbows is relatively simple. At that time, you only need to select some craftsmen and give them simple instructions to assemble them in large quantities. As for the explosive arrows and bow strings, all the parts need to be processed before they are made.

Now they have boring machines and milling machines, and they have also mastered special charging methods. They can make explosive arrowheads with ease. As for the craftsmanship of the bowstring, they had no better way. They really had to rely on swordsmanship to cut it out. After all, the conditions did not allow it, and there was no equipment to pull out the wire. However, they also have a temporary solution. They use two steel wires and oil-soaked beef tendons to wrap around each other to form a bow string. This not only reduces the demand for steel wires, but also increases the elasticity of the bow string. The durability of a bowstring made by simply wrapping three steel wires is still not as good as that of a traditional bowstring. Of course, this is also their temporary assumption, because relying on swordsmanship to cut steel wire is too ridiculous. Even if it has not been implemented yet, just thinking about it, Li Yu himself finds it funny. The most reliable method is to use multiple pieces of twine and beef tendons to be mixed and wound, but it must undergo final testing before deciding what kind of material to use to make the bow string.

3 months later. Li Yu and Wang Qingyang finally processed all the pulleys, crossbow parts, and bow arms. In the past three months, the two of them have only rested for 4-5 hours almost every day, and the rest of the time has been spent cutting and polishing parts. At this time, the entire workshop was filled with various parts and components that had been processed by them. If you didn't look carefully, you wouldn't be able to find that there were actually people working in the workshop.

In the past three months, Li Yu and Wang Qingyang, in addition to cutting and polishing these parts, also took a little time to solve the problem of bow strings. In the end, they gave up using swords to cut out steel wires. This weird idea came to me. What is used is fiber silk made from the dried roots of several plants unique to this world, and then mixed with twine for winding. As for why beef tendon is not added, that is because beef tendon is too difficult to buy. As for the fibers made from these special plant rhizomes, Yuan Xiuxiu only learned about it after making many inquiries in the town. . After Yuan Xiuxiu learned about this material, she ordered a large batch according to Li Yu's request. Since these materials can be purchased in Leisure City, this batch of plant fiber silk quickly reached Li Yu's hands.

After actual testing of these special fibers by Li Yu and others, they found that their toughness is much better than that of steel wires. Even without the use of spiritual energy, ordinary weapons cannot cut through the fibers and the fibers. Bow strings are made of mixed twine and twined with hemp threads. Their prices are also ridiculously low. People in this world like to weave this kind of fiber into thick ropes, which are specially used to pull carriages or make cranes. Rope is used to transport materials for building pavilions.

Only Li Yu and the others found a new way to make bowstrings from this kind of fiber. After all, in this world, most of the mainstream bowstrings are soaked in various animal sinews. Li Yu's bowstrings, which are mixed and wound with plant fibers and hemp threads, are also inspired by modern composite fiber materials. To a certain extent, Li Yu's bowstring can barely be classified as a composite fiber, but their production technology is still too crude compared to modern times.

After the bow string problem is solved, what is left now is to train the craftsmen. After all, assembling hundreds of pulley crossbows and dozens of pulley bows is a big project. Because in the new workshop, all the work on making arrow shafts has been completed. So this time, Li Yu and Wang Qingyang mobilized all the workers back to help them complete the final assembly work.

As for the job of training craftsmen, it naturally fell to Wang Qingyang. Because Li Yu needs to make dozens of explosive arrows in the next time. To make an explosive arrowhead, the first step is to make a hollow cone-shaped arrowhead, then install a firing device at the tip of the arrowhead, and finally fill it with black powder. Since the firing method of explosive arrows is different from that of bullets, it is the firing pin at the front that causes the gunpowder to ignite after a violent impact, and finally creates an explosion effect. Therefore, the entire explosive arrow head can be cast. After all, it is a disposable consumable, and it is also designed to better shatter the metal wrapped in the arrow at the moment of explosion, thereby causing more fragmentation damage.

Since the arrows use a casting process, Li Yu can actually achieve mass production very easily. However, due to the storage of explosive arrows, great caution is required. Therefore, he did not dare to make too many. After all, he could not guarantee that every soldier could properly keep this special arrow. Not everyone can have storage bags like him and Wang Qingyang. Moreover, after so many years of various collections, and this time they needed to hold the parts of the boring machine and milling machine, their storage bag space was almost filled up, and naturally they could not carry more special items.

As for why we need to carry the parts of the boring machine and milling machine, of course, these two guys are too big. If they are not disassembled, they cannot be put into the storage bag, let alone take them away from here. .

The shortage of storage space this time also made Li Yu and Wang Qingyang realize that if they want to continue to develop, they probably have to go to the Great Rift Valley. The Great Rift Valley has too many resources that they urgently need. First, store Of course, it goes without saying the bag of things, but the second one is the spirit stone! In this lower realm, there are too few ways to obtain spirit stones. Unless you can own an entire vein of spirit stones, then you can definitely dominate. But Li Yu and the others did not, so this is the biggest reason why Li Yu coveted Yunhe Island among the nine islands.

Although he has been coveting it for a long time, he is still self-aware. After all, they haven't even conquered the Red Copper Island yet. They just want to conquer the Red Copper Island. They spent nearly a year just preparing here. . Not to mention thinking about attacking Yunhe Island, this is completely fanciful.

Thanks to the overtime work of more than 100 craftsmen day and night, hundreds of pulley crossbows and dozens of pulley longbows were all assembled after one month. At this time, rows of crossbows, longbows, and boxes of arrows were all neatly placed in the forging workshop. Li Yu also completed the production of more than 80 explosive arrowheads. Because he was worried that the soldiers would not be able to store them properly, he also thoughtfully put all these arrowheads into his own private storage ring.

And all of them will end their one-year blacksmith career on this day and will leave this forging workshop full of stories and sweat.

After Li Yu and Wang Qingyang counted all the weapons and equipment and confirmed that the numbers were correct. He also gave the last order to the craftsmen. That is, everyone immediately started packing their luggage and evacuated Tieshi Town in batches after nightfall.

At the same time, Li Yu also asked Sun Hongyan to go first to the valley and notify Fu Lingshuang, asking her to send some people and horses to Tieshi Town 20 miles away to standby. After the evacuees here arrive, they will be responsible for the response work.

As for Li Yu and the others, they are responsible for the follow-up work. After all, they need to inspect the two workshops and the small courtyard where they live, and at the same time clean up and cover up the traces they have left this year. Although this work is not particularly important, Li Yu, who is always known for his caution, will naturally not let go of these details, just like when they left Donglan County. Without his caution, Maybe they won't survive today.

Eight hours later, the last batch of craftsmen evacuated. Li Yu and Wang Qingyang stopped and waited for a few more hours. After the two workshops and the small courtyard where they lived were set on fire. They relied on their excellent light skills to quickly leave Tieshi Town.

As for Jin Yang, Yuan Xiuxiu, Mo Wuhen, and Wang Qingyang's two concubines, they had already evacuated to Tieshi Town 20 miles away with the last batch of craftsmen under the arrangement of Li Yu and others.

Twenty miles outside Tieshi Town, Fu Lingshuang had already taken in all the last batch of evacuated craftsmen. Among all the people who have worked in Tieshi Town, only Li Yu and Wang Qingyang have not arrived yet. Fu Lingshuang naturally did not worry about these two people. After she counted all the people and confirmed that they were correct, she ordered everyone to quickly withdraw from Tieshi Town and go straight to the direction of the valley.

Li Yu and Wang Qingyang were already galloping directly towards the valley station. They did not consider whether Fu Lingshuang would wait for them, so they knew Fu Lingshuang's character very well.

More than two hours later, Li Yu and Wang Qingyang finally arrived at the valley station. With this, the one-year station basically came to an end. However, they did not plan to evacuate immediately overnight, so Li Yu and the others still had an important task that needed to be handed over to the soldiers. That is the assembly and training of the pulley crossbow. As for the training of the pulley bow, Li Yu left it to his wife Fu Lingshuang. After all, Fu Lingshuang was proficient in bow skills. It was most suitable for her to select a team dedicated to using pulley longbows and explosive arrows. The cross-shooting training of the pulley crossbow was jointly performed by Li Yu and Wang Qingyang.

In the next week, they conducted many practical trainings in this valley using the complex terrain around the valley. At the same time, after this week of training, Fu Lingshuang also selected a platoon of soldiers among these soldiers to practice the pulley longbow with her. Fu Lingshuang was very satisfied with the pulley longbow made by Li Yu. She had never seen such a weird-looking longbow, but when she tried to pull out the first bow, she couldn't calm down at all. The power of this long bow far exceeded her knowledge. At the same time, combined with the special spiral arrow, she could shoot an arrow over a hundred feet away. This range, this lethality. How could she not be surprised.

But what surprised her the most was more than that. What surprised her the most was that Li Yu actually made an explosive arrow. She had been suspicious before, suspecting that Li Yu was just joking with her. But when Li Yu installed an explosive arrow in front of her, she gave up the idea completely, although she didn't know the power of the arrow. But at Li Yu's instigation, Fu Lingshuang decided to test the explosive arrow. When she truly saw the power of the explosive arrow, she began to have deep doubts about the original bows and arrows in this world. Under the power of this explosive arrow, the original bows and arrows in this world are as weak as children's toys.

But Li Yu must be used to being a dog. Just when Fu Lingshuang was still shocked by the power of the explosive arrow, he took out his revolver in front of her again. Revolvers are naturally familiar to modern people like Li Yu. Even if you have never seen the real thing, you can often see it in film and television works or online game centers. But Fu Lingshuang was different. She had never seen such a strange-looking weapon. The moment she took the revolver from Li Yu, she only felt that the weapon was very light, but its appearance was very delicate, as if it was a weapon. Ornaments for collection are generally used. But when Li Yu told her that this was a weapon more powerful than a bow, she didn't want to believe it.

Li Yu had naturally expected Fu Lingshuang's doubts. He took the revolver from Fu Lingshuang and showed Fu Lingshuang how to use the weapon.

While demonstrating, he also told Fu Lingshuang, "The gun is the fastest ten steps away."

Fu Lingshuang asked with confusion on her face: "What about within ten steps?"

"The gun is fast and accurate within ten steps." Li Yu replied with a wicked smile.

Fu Lingshuang said she didn't believe it. But before she could finish her words, she heard a "bang" and a tree not far from Fu Lingshuang's side had been pierced. When Fu Lingshuang reacted, a short time had passed. she asked with a look of horror on her face

"When did you take action? Why didn't I feel it at all?"

Li Yu proudly turned the revolver in a circle, and then said, "When the sound was heard, the tree had already been penetrated. If you use this weapon in the future, when the enemy hears the sound, he will be dead." Understand?"

This concise and easy-to-understand answer refreshed Fu Lingshuang's world view again. She was very sure at this time that this was the kind of fire-breathing weapon that Li Yu had told her before. However, she still spoke and confirmed again:

"This is the kind of weapon you once told me that can breathe fire in your upper realm. It's a very special and powerful weapon, right?"

"Well, this is just one of them. There are many types of this kind of weapon. They have a unified name, called: gun. The one I have now is also one of the weaker ones among the many guns. It is really powerful. Yes, I don’t have time to make it yet. After we take down the red copper island, I will make one for you alone. But I will leave this one to you for your daily use. For self-defense at close range." After saying this, Li Yu handed the revolver to Fu Lingshuang. He also took out 50 rounds of ammunition from the storage bag and gave them to her.

After Fu Lingshuang took the gun, she asked a little embarrassedly: "You gave it to me, what about you?"

"I still have it. I made a total of 6 guns, each with 50 rounds of bullets, but I just shot one round, so I gave you one round from my 50 rounds." Li Yu said, While taking out his own revolver.

The two revolvers owned by Li Yu and Wang Qingyang were both specially carved, while the two revolvers owned by Yuan Xiuxiu and Jin Yang were. There are also engravings. Only Fu Lingshuang's one has no patterns or words on it.

Fu Lingshuang looked at the pistol Li Yu took out at this time, and then looked at the one in his hand. She suddenly curled her lips and said a little unhappily, "Why, yours looks different? Why are there such fine patterns on it?"

"That's because I'm a producer! It's a bit of a privilege, but it's not too much, right?" Li Yu said with a proud look on his face

"It's not too much, but I think yours looks better than mine. How about we switch?" Fu Lingshuang stared at Li Yu's revolver with a look of envy on his face.

"If you don't change it, this is the privilege of the maker. I will teach you how to make a gun later, and you can make it yourself." Li Yu quickly put away the gun.

Seeing that Li Yu was afraid that she would steal his treasure, Fu Lingshuang could only give up. Since Li Yu promised to teach her how to make guns in the future, she could only make beautiful-looking guns for herself in the future.
