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

The two worked hard until dawn the night before finally producing more than 30 rounds of 7.62 special bullets. The bullet's warhead is made of silver mixed with alloy and spirit stone powder, while the bullet casing is made of brass. The charge ratio is also very particular: 75% gunpowder and 25% spiritual energy powder.

For the primer part of the bullet, since they currently lack important chemical raw materials such as chlorate, mercury fulminate, and lead azide, Li Yu took a new approach and used black gunpowder plus a small amount of spiritual stone powder and a unique fire crystal in this world. Mineral rock powder is used to make a primer. Lingshi powder can greatly improve the stability of the primer and prevent it from exploding immediately when it receives a slight shock.

The fire crystal mine is a unique ore that Li Yu and the others found in the market in Gulan City. At least in Li Yu's world, they have never seen this kind of ore. This kind of ore has never been seen before. After the ore is ground into powder, a little gunpowder is added to mix it, and after being wrapped in kraft paper, it can produce an effect similar to throwing a cannon.

Basically, it will explode on its own as soon as it receives a violent impact. After careful study by Li Yu, he found that adding a small amount of spirit stone powder to the mixture of igneous rock ore powder and gunpowder can greatly increase its stability, but at the same time it does not affect its ability to be struck by the firing pin. The explosive properties produced after being broken. Therefore, after several experiments, Li Yu also decided to use this special rock ore to make bullet primers.

In this world, people usually mix the powder of this igneous rock ore with gunpowder to make cannon balls for children to use for daily fun. The more high-end usage is that people in the world mix this fire crystal rock ore powder with a small amount of black gunpowder, plus several special materials, to create a smoke bomb for escape. No one is like Li Yu. Think of using this kind of thing to develop weapons.

That day, in the afternoon, the two of them slowly got up from the bed. Although they were still sleepy, the excitement of testing the gun later still lingered in their minds. So they quickly put on their clothes, then washed briefly, and then walked out of the room. After leaving the wing, Li Yu shouted loudly:

"Jin Yang! Xiuxiu! Come out quickly! I'll take you to a long experience!"

Last night, because he was smelly of sweat and it was almost dawn, Wang Qingyang spent the whole night with Mo Wuhen at Li Yu's place. When Li Yugang called Jin Yang and his wife, he just walked out of the room. At this time, Jin Yang and his wife heard the sound and walked out of the side room.

Yuan Xiuxiu: "What are you shouting for! I was just going to take a nap!"

Wang Qingyang "Hurry up and get in the car! It's too late to explain!" After saying that, Wang Qingyang was the first to rush out of the door, and Li Yu also waved to Yuan Xiuxiu and his wife, and then followed.

Yuan Xiuxiu and Jin Yang looked at each other, and finally decided to follow them to see what was going on.

After Li Yu and his wife, Jin Yang and his wife, quickly arrived in the woods, Fatty Wang proudly took out a revolver with a silvery cold light from his storage bag. He waved the gun twice in front of Jin Yang and his wife. Jin Yang and Yuan Xiuxiu's eyes suddenly stared like bells. Jin Yang said with a look of disbelief:

"I'll go! Are you a real guy?"

"You are talking nonsense! Your Grandpa Wang never buys fakes!"

"Oh my god! You guys did it all! I feel so safe now!" Yuan Xiuxiu said with surprise on her face.

"This is just a revolver. It's not that exaggerated! Look at you, you feel so safe!" Li Yu joked.

"Okay, fat man, load the bombs. Fill up all 7 rounds and prepare for test firing." Li Yu ordered

"I'm just waiting for your words!" Fatty Wang responded to Li Yu at this time and took out a handful of bullets from the storage bag.

Jin Yang and Yuan Xiuxiu watched carefully from the side, and they heard very clearly that this was the first pistol that Li Yu and his wife tried to make, and he and his wife were invited as spectators to visit this first pistol. A test firing experiment. At this time, they were also quite excited.

As Wang Qingyang finished loading, he pointed his gun at a big tree more than 30 meters away from him. After pressing the hammer, the trigger was immediately pulled. Just hear a crisp "bang" sound. A big hole was immediately punched through the big tree a hundred meters away. At the same time, a trace of white smoke also came out of the pistol, but the smoke was not obvious. You have to pay very careful attention to see the trace of white smoke floating out of the muzzle. This made Li Yu, who had been paying close attention to the changes in the gun body with his spiritual consciousness, a little surprised.

So Li Yu once again put his spiritual consciousness into the muzzle of the gun and carefully scanned it back and forth, and he had the answer in his heart.

"It seems that the temperature increased by this spirit stone powder to the gunpowder has burned out most of the black gunpowder residue, which is far beyond my expectation. Perhaps, just based on the mixing of black gunpowder and spirit stone powder, if If the perfect ratio can be tested, it can also be used as a smokeless gunpowder!"

"Really? I didn't pay attention just now. But after the bullet was fired, the smoke from the muzzle was very slight."

After Li Yu nodded, he took the revolver from Wang Qingyang. He pressed the hammer and then quickly fired a shot into the distance. Then she immediately covered the direction where the bullet was ultimately shot with her consciousness. After some searching, he determined the final location of the bullet. After silently calculating in his mind, he said:

"The effective range exceeds 40 meters, which is basically close to the minimum standard for military pistols. Not bad, this gun! The bullets are also quite good! More than 50 meters is already within the scope of modern pistols!"

"Is it that far away? Did you use your spiritual consciousness to track the trajectory of the bullet just now? Isn't this 40 meters about the same as the range of a spiral armor-piercing arrow?"

Li Yu shook his head and replied, "The spiral armor-piercing arrow is stronger. Don't forget, I used an ordinary bow and arrow that day, but if the penetration is about 40 meters, the two should be about the same. But if the spiral armor-piercing arrow If you change the bow, it should be slightly better. However, in terms of effective range, the spiral armor-piercing arrow combined with the sliding bow can throw this pistol several blocks, and it is estimated that it can reach at least 300-400 meters. The function of this pistol is actually the same as The cross-slip crossbow we are preparing to produce in small batches has similar functions. However, in terms of penetration, the advantage of bullet kinetic energy is unmatched by crossbows."

After listening to Li Yu's explanation, Wang Qingyang remembered that this was indeed the case. The bow used to test the spiral armor-piercing arrow that day was indeed an ordinary hunting bow.

Then Li Yu and Wang Qingyang handed the guns to Jin Yang and Yuan Xiuxiu. Under their guidance, Jin Yang and Yuan Xiuxiu each tried firing a few shots. Since this pistol is made of alloy, and its size and weight have been carefully adjusted by Li Yu, Yuan Xiuxiu is quite easy to use. Naturally, Li Yu and his wife also told them that they were going to equip each of him and his wife with a revolver. And Yuan Xiuxiu also said:

"Leave the belt and holster to me!"

Jin Yang: "Recently, I have been learning forging skills from Brother Li, so leave the casting of the belt buckle and gun butt buckle to me."

Li Yu naturally agreed to Jin Yang and his wife's self-recommendation. Since today's ammunition was all trial type, Li Yu had no intention of keeping the ammunition. He divided the ammunition into four equal parts, and each of the four of them could try to fire a few more shots for practice. After the bullets were completely empty, Li Yu also picked up the pistol and used his spiritual consciousness to conduct an in-depth inspection of all the structural components of the entire gun. Especially the rifling part in the gun bore. After more than 30 rounds of continuous shooting, the rifling was not as previously imagined, leaving a large amount of black powder residue. This should also be due to their charging formula. The reason is that Li Yu also plans to do further research on this issue after returning to the workshop.

After several people finished using up their bullets, they returned to the small courtyard together. Yuan Xiuxiu asked Sun Hongyan to accompany her to the town to purchase animal skins needed to make gun holsters. Jin Yang, on the other hand, changed his clothes and plunged into the forging workshop, planning to try making belt buckles and gun holster buckles. Wang Qingyang asked Qin'er to boil a large bucket of hot water for him, preparing to take a nice bath.

Seeing that everyone had their own arrangements, Li Yu naturally went to the forging workshop dejectedly and continued to study the revolver and bullet charging in depth. In fact, Li Yu had discovered a long time ago that the spiritual stones in this world have various special uses. For example, the iron mace in Wang Qingyang's hand has the special effect of absorbing spiritual energy and releasing spiritual energy. Some of the ordinary spirit stones they currently have in their hands have the effect of increasing temperature and increasing penetration. Li Yu even boldly guessed that there would be so many types of spiritual stones in this world that even the monks in this world might not be able to recognize all the spiritual stones. And they had obtained various spiritual stones many years ago deep underground in the Great Rift Valley. However, due to lack of research time, they have not been able to conduct in-depth research on this batch of spirit stones. After all, if they want to fully understand the properties and effects of each spirit stone, it will take a huge amount of time to conduct experiments.

As for how the spirit stone was generated, Li Yu also made some speculations from some fragments of words collected over the years. He felt that the spiritual stones in this world might be the result of the unique spiritual energy of this world, which after endless years of baptism, was fused with some special rocks, resulting in some mutations. Since the types of rocks in various regions are different, and the materials contained in the rocks are also very different, the abilities attached to the eventually formed spiritual stones are also very different. The spiritual stones they currently hold should be the most common and common type, so they are used as currency by the upper world. As for how many types of spirit stones there are in the world, given Li Yu's current situation, he definitely doesn't have the conditions to know.

Although he has no way of knowing how many types of spirit stones there are, since he has a basic spirit stone in his hand, and it is not difficult to obtain this kind of spirit stone, he will naturally develop this kind of spirit stone. available range. After all, he could clearly feel it after this mixed use of black gunpowder. There are many uses for this kind of spiritual stone powder. It’s just that people in this world lack the spirit of scientific research, so they just use this excellent and special ore as an ordinary item. When Li Yu arrived, this spiritual stone In your hands, this can become a delicious and rare ore!

Next, Li Yu took out some spirit stones and crushed them, and then he began to redesign the 7.62 mm bullet. It was not the design of the bullet shape, but the redesign of the ratio of the bullet charge. . Since this kind of spirit stone powder is so flammable and can also increase the explosion speed to a certain extent, Li Yu will naturally make more fine adjustments to the ratio of black gunpowder and spirit stone powder. This time, he used the method of first filling the bottom of the cartridge case with a layer of pure black gunpowder, then filling the black gunpowder with a layer of spiritual stone powder, and finally filling the mixture of black gunpowder and spiritual stone powder to the top. The effect of such filling, in his imagination, is to increase the combustion-supporting effect of the spirit stone powder on the gunpowder, thus further reducing the residue left by the burning of black gunpowder. At the same time, after the firing pin fires the black powder layer at the bottom of the cartridge case, the ignition of the black powder layer will instantly ignite the layer of spiritual stone powder, thereby increasing the kinetic energy of the warhead out of the shell. However, this is just Li Yu's idea. How it actually works can only be known through actual testing. But he was not in a hurry. After he loaded dozens of 7.62 bullets with this new charging technology, he stopped loading the bullets.

Next, he needs to dismantle the prototype revolver. Although he has done a detailed inspection with his spiritual consciousness before, the specific situation still needs to be disassembled and then carefully inspected, which is more intuitive. About twenty minutes later. He broke the entire revolver into parts. He took a white cloth and began to wipe the parts one by one. Through this wiping, he could clearly know which parts were contaminated with black powder. The residue left behind. This allows for a more detailed inspection of this individual component.

After more than an hour of inspection, Li Yu discovered that the bullets were loaded with black powder and spirit stone powder. After being fired, the residue remaining on the gun was almost the same as smokeless gunpowder. After updating the charging process this time, he was confident that the residue could be suppressed to even less! At the same time, he also had more expectations for the next step of making a mixture of gunwool and spirit stone powder... because there was a question in it that had always interested him. Guncotton is nitrocellulose. It is a very unstable substance, but Lingshi is just the opposite. Although Lingshi can produce huge energy and heat, it is extremely stable. If Lingshi powder is fused with nitrocellulose, what will happen? What kind of chemical reaction occurs?

Although Li Yu is looking forward to doing this experiment, he currently does not have the conditions. He still needs to defeat the Red Copper Island before he can slowly study this issue. After all, the special materials such as sulfuric acid and ether required for making guncotton require glass equipment. At the same time, glass instruments need to be fired with silicon. Such a complicated and cumbersome task is naturally beyond his current ability. Therefore, he could only suppress these expectations in his heart for the time being.

With the new charging technology, Li Yu naturally needed to test it carefully, so he cleaned and wiped all the parts of the revolver, reassembled it, and then filled the pistol's magazine with newly made Bullets come out. With this pistol filled with ammunition, he once again came to the woods where he had just tested the gun.

Li Yu held the pistol in his right hand, slowly raised his arm, pointed it in the distance, pressed the hammer, and pulled the trigger. The moment the bullet came out of the barrel, he immediately used his spiritual consciousness to lock it, firmly locking the trajectory of the bullet, and at the same time his eyes fell on the muzzle of the gun. Just as he expected, after updating the charging technology and ratio, the muzzle no longer emitted gunpowder smoke, but a little bit of white mist drifted out next to the magazine. It was very slight. If he hadn't locked his eyes with his hand earlier, The gun was not noticed at all. At the same time, his consciousness also tracked the impact point of the bullet. This time, the range exceeded 50 meters, and even approached almost 60 meters before it slowly fell.

Although it was expected, when he actually saw it with his own eyes, he was still very surprised. After all, the success of this test also indicates that in addition to making sliding bows and crossbows, they may also try to make automatic rifles or bolt-action rifles. Because the problem of bullet charging has been perfectly solved! The only shortcoming is that with his current charging technology, most of the gun parts must be forged parts to withstand the detonation and huge recoil. This charging process is due to the mixing of a large amount of spiritual stone powder. Therefore, the moment the bullet comes out of the gun, the detonation and recoil will be very obvious. At the same time, this kind of detonation and large recoil will also put a great test on the durability of the gun parts. If you want to be lazy and use partial castings and only use the forging process for the barrel, then I am afraid that the gun body will fall apart after just a few shots.

As for the impact of the gun's detonation and large recoil on shooting accuracy. Li Yu doesn't care at all. Are you kidding me? Everyone in Li Yu's team is basically a martial arts monk. No matter how low the level is, there is still no problem in suppressing the explosion and the huge recoil. If it were a fully automatic rifle, it would take a martial arts monk with a slightly higher level to suppress it. After all, it takes a few seconds to empty a magazine. The recoil was really terrifying. Originally, rifles like AK were already recognized as difficult weapons to suppress, and coupled with Li Yu's crazy special charging method. He himself is also very clear about how difficult it will be for the AKs they produce in the future to hit the target. It is definitely no exaggeration to judge the master of human body contouring. Therefore, Li Yu could only temporarily suppress the idea of ​​making a rifle. After all, he still had to think carefully about how to solve the huge recoil and detonation problems caused by this bullet.
