Not to mention that the Thunder Tribe is fully prepared for the upcoming war, the insignificant alchemist Ulapox, who was caught by Robben before, has not been treated with the prisoners of war that he originally thought he would encounter, and he did not even treat him at all. Everyone in the Thunder Tribe treated him like those wandering barbarians who came to join him. He could get the corresponding reward by paying some of his labor every day.

At the beginning, Lord Ulapox was thinking about whether to sneak back to the Northern Tribal Alliance. After all, he was a rare alchemist there, and he was not treated as a match and did not need to work like this every day. However, with several subsequent battles in Robben, Ulapox completely gave up this idea. He had seen the power of alchemy with his own eyes. With the emergence of advanced weapons of the Thunder Tribe one by one, Ulapox clearly realized that it was unwise to be an enemy of the current Thunder Tribe, especially when Lord Ulapox saw the improved artillery, he was more sure of this, so Lord Ulapox gave up the idea of ​​running away.

Although giving up running away does not mean that he does not want to live a superior life. Lord Ulapox has lived enough of this kind of life that trades labor for food every day. He has no other people's fighting skills, so he has to continue to use his mind to alchemy.

Ulapox knew that the alchemy he brought was not as good as the Thunder Tribe. Fortunately, the goblins had already joined the Thunder Tribe, so the opportunity for Lord Ulapox came. So after changing enough rations every day, Lord Ulapox stopped working, but secretly ran to the gathering place of the goblins and secretly learned the alchemy of the goblins. Don’t say that, over half a year, Lord Ulapox’s alchemy water rose sharply.

He discovered a situation where goblins are extremely obsessed with mechanical puppets, which may be due to the short figure of goblins, so goblins have been committed to developing tall goblin puppets to protect themselves. Therefore, goblins have very high mechanical manufacturing level, far exceeding most craftsmen who are also skilled craftsmen in the Thunder Tribe. So Ulapox put a lot of effort into this and carefully studied the mechanical manufacturing technology of goblins.

Don't say, opportunities are always left to those who are prepared. As Ulapox's mechanical production level rises linearly, many of the Thunder Tribe's weapons principles that were not understood in the past, slowly, Lord Ulapox can see a general meaning. Combined with his own research, let alone let Ulapox develop alloy forging technology and perfect the seamless steel pipe production process, which made Robben highly praised him and gave him a house for research by himself. And with this preparation, Lord Ulapox once again discovered an opportunity to prove himself.

It turned out that it was an improvement of the new rifle. Lawrence and others made improvements to the shell-splitting mechanism of the new rifle, which could fully meet Robben's requirements. However, there was no good way to portray the rifle, and they could only be hand-carved. Ulapox noticed that dozens of craftsmen had made seamless barrels in recent days, and they were carrying hook-shaped knives to carve something inside the steel pipe bit by bit. So the curious Ulapox found Lawrence and asked what was going on. Lawrence told Ulapox about Robben's rifle theory intact, and Ulapox also made careful records. After returning, Ulapox entered a state of retreat and fought with the rifle, vowing not to go out of seclusion if he didn't study one, two, three days and three nights, Ulapox did not rest at all, which really made him study something.

Through research, Ulapox found that the length of the barrel has a great impact on the initial velocity of the shooting. Within a certain length, the longer the better. The barrel's material requirements are not only hard, compressive resistance and high temperature. Another essential characteristic is its stature, which means that the barrel must also have a certain elasticity, otherwise it will cause the metal to be too brittle. If you continue to shoot, there is a risk of blowing up the barrel.

After the rifle is carved, the barrel forms two parts. Ulapox calls the concave part of the barrel the negative line and the raised part called the positive line. Generally speaking, the caliber of a gun should be the distance from the positive line of the rifle to the positive line, but there are too many exceptions, which cannot be a principle. Some measure the distance between the positive line and the positive line, while others measure the distance between the negative line and the negative line. Of course, the length of the bullets of the two is different, but the light is the same in terms of the diameter. So Ulapox first set a standard himself, that is, the diameter is based on the distance between the positive line and the positive line.

As for the degree of rifle rotation, Ulapox asked Robben for advice, he said it was just a wrapping distance. If the longer the distance is needed to complete a 360-degree rotation, it is called slow, and the shorter one is called fast. For example, if one completes a round within 12 inches, it is slower than one within 9 inches. The difference in wrapping distance is mainly whether the warhead can be stabilized. In addition to rotating along the target line, an unstable warhead will also turn into somersaults, affecting the shooting accuracy.

After careful research by Ulapox, there can be several types of rifling: cutting method, die extrusion method, and precision forging method.

The cutting method is the most primitive rifling processing method. Now the Thunder Tribe basically uses this method to make it. This rifling processing method is to use a hook-shaped turning tool to penetrate into the eyes of the blank, then pick the material bit by bit, slowly form a groove. During the picking process, the tool or pipe can keep the groove at a certain slope, so the grooves will become rifling. The cutting method is very labor-consuming and time-consuming and is not suitable for mass production. However, this processing method has little damage to the metal structure of the barrel and is suitable for processing high-precision barrels. A skilled old gun smith can process high-precision barrels.

The first method of making the production was the die extrusion method. The method was to drill a smaller hole on one end of the barrel, and then use a high-hardness die with a protrusion corresponding to the rifle, and use a mechanical to force the spinning and squeeze the material into rifle and rifle. Ulapex referred to the machinery of goblins to make puppets and made a simple rifle cutting machine. However, the "extrusion method" will harden the local part of the barrel and may also cause internal injuries to the barrel (may blow up the barrel), especially the barrel with higher hardness. Therefore, in general, the "extrusion method" is only suitable for small-diameter short-barrel guns, but due to the use of mechanized forging, the production speed of rifle is greatly improved.

Later, Ulapox conducted in-depth research again and invented the method of precision forging. To put it simply, it is to insert a core rod with external rifling into the pipe and smash it with a special hammer outside the pipe. Although the yield rate is high and fast, it is just a product. Any metal hit by a hammer will produce internal stress. Think about a barrel with so many chaotic stresses. The accuracy of the shooting is definitely difficult to guarantee, but it is much stronger than an old-fashioned musket without rifling, and the range is also greatly improved! Large cannons or precision rifles still have to use old-fashioned cutting methods to depict the rifle.

When Ulapox put his research results in front of Robben, Robben was completely shocked after reading it. Unexpectedly, Robben had forgotten his existence when he caught a tongue inadvertently. He was actually a master-level figure. It took only three days to greatly improve the original cumbersome rifle drawing technology. Although the barrel carved according to the portrayal method designed by Ulapox was difficult to achieve high accuracy, Robben did not build sniper rifles, and was definitely more than enough to make standard rifles used in the tribe.
