Obviously, when Nie Xiaoyu said that he wanted to build a gun for Wang Junlin, he had made preparations for a long time in advance, and this lathe was only one aspect, and Nie Xiaoyu next took out a piece of steel the size of an adult's head, ten taels of silver with very high purity, a piece of copper with almost no impurities, and so on, all kinds of materials were placed next to it one by one, which fully illustrated this point.

Nie Xiaoyu's operation is so accurate that it is not at all human beings can do it, and the speed is very fast without any superfluous operation, but it took half an hour for a barrel to be made, Wang Junlin watched from the side, and found that although it was only a smoothbore, he also knew that the accuracy of the chamber was at least at the level of the musket during the First World War.

After two hours, all the spare parts were made by Nie Xiaoyu in turn, Wang Junlin made each accessory next to him, and after a little research, he began to install, and after Nie Xiaoyu created the last accessory, he already had a complete musket in his hand.

This is a musket between a rifle and a pistol, without any paint, pure steel primary color, it looks stiff, and it feels cold in the hand, but at this time, Wang Junlin's heart is hot.

In addition to his own excitement because he had a gun in his hand again, this kind of heat was more about thinking about the scene of his army sweeping the world with muskets, so his heart was on fire.

Of course, Wang Junlin knew that guns were not high-tech at all, and he even remembered that in later generations, a certain province in the northwest plateau cracked a huge gun sales case, in which two brothers who graduated from high school took books related to the structure of guns bought from bookstores, studied them for a period of time, and then ordered related machinery such as lathes to manufacture guns.

Wang Junlin even knew that because of the black fire. The accuracy of the drug formula, the bullet is a little more cumbersome to make than the gun.

The gun in Wang Junlin's hand was about eight inches long, and it was a medium-barreled musket with a caliber of 15 millimeters.

Because Nie Xiaoyu personally created all the parts, the inner chamber of the barrel was polished to be extremely smooth, Wang Junlin had previously held the barrel and looked up at the light, and found that the inner wall was even reflective.

Because spring steel has extremely high requirements for the material of steel, the only thing that is not so good about this gun is that the elasticity of the power reed is much worse than that of later guns, and the bullet shooting distance and speed may not be as good as that of later generations, but it is enough in this era.

This gun uses black fire. After firing the medicine propulsion and creating all the parts of the gun, Nie Xiaoyu directly began to build the bullet, which is actually the cartridge case and the warhead.

Because although the bullet case will appear after the bullet is shot, when making the bullet, the bullet case can also be made after the bullet is used.

In order to save the process, the material Nie Xiaoyu chose can be directly used to make silver for bullet cases and warheads without going through any processing procedures.

It cost ten taels of silver to make a hundred silver shells and a silver solid warhead in one go, and a hundred small bullet bottoms from specially treated copper. fire, and a thunderbolt was installed in it. mercury and then use the powerful instantaneous impulse of the lathe to place the bottom. The fire pressed on the bottom of the cartridge casing.

The next thing Wang Junlin can also help, that is, the black fire of the particles made by Nie Xiaoyu in advance. The medicine was poured into the bullet case little by little, and pressed solidly, and finally used the instantaneous strong pressure of the lathe and Nie Xiaoyu's accurate operation skills to press the bullet case and the bullet together.

Wang Junlin knew that even if someone witnessed Nie Xiaoyu's process of making guns and bullets today, and had the same lathe machinery, it would be difficult to make a gun, let alone bullets.

After the bullet was made, Wang Junlin pressed the bullet into the gun on the spot, and conducted a test gun, and he was pleasantly surprised to find that the accuracy of this gun was much better than that of his similarity, that is, the firing range was only 80 meters, and the effective range was about 50 meters, and there was no lethality beyond 50 meters.

In terms of range alone, even some strong bows are not as good, Wang Junlin knows that it is because of the lack of elasticity of the power reeds, mainly because of the lack of spring steel.

However, compared to the bow and arrow, this gun is naturally much faster to complete the fire, and the speed of the bullet is far from being comparable to the bow and arrow.

More than forty meters away, a rabbit prepared by Nie Xiaoyu in advance was directly broken by Wang Junlin's shot as soon as he got out of the cage, and it has such power because the caliber of this gun is larger than the caliber of ordinary guns in later generations, and the diameter of the bullet is naturally larger.

Although the range is a little disappointing, this is the first gun made by Nie Xiaoyu after all, and Wang Junlin believes that the next time Nie Xiaoyu makes a second-generation gun, the range problem will be greatly improved.

What's more, even if it was this gun, if he fought within fifty meters, even if he had a certain confidence in injuring the other party against a strong person like the Spring and Autumn Envoy and the Sword God, he would at least be able to establish an invincible position. As for the martial artist under the grandmaster, as long as he grasps the timing of the shot, he can kill it with one shot.

Guns are all manufactured, how can there be no grenades and mines that are much easier, Wang Junlin followed Nie Xiaoyu and saw the power of grenades and mines again, and then left Nie Xiaoyu's private research and production field with satisfaction. The next thing was the issue of mass production of grenades, mines, and guns, and there was still plenty of time for King's Landing to use such sharp weapons for at least three years.

In the next three days, Wang Junlin and Nie Xiaoyu conceived and deduced their overall plan for the next step, and the plans and plans of some specific tasks, and after setting some general things, the specific details were left to Nie Xiaoyu to fill in, and Wang Junlin left Snake Island three days later.

However, he did not return to Fanyang County, but continued to the northeast, which was the direction of Goguryeo, so he naturally did not go by a ship, but left with a hundred large and small warships, a full 4,000 officers and soldiers of the naval division.

Yuan Gai Suwen, an unlucky child, has been in the hands of Wang Junlin for more than a year, and has suffered too much, and his father Yuan Taizuo also met all his requirements in accordance with Wang Junlin's agreement, and it is really unreasonable not to return his son to others, of course, the premise is that Wang Junlin controls the two islands that Yuan Taizuo promised him in his hands.

"Ocean currents?"

Zhang Tiangang and Wang Junlin's guards were listening to a dark-skinned, early twentieth young man explain some basic knowledge of sea navigation, but the words spoken by this young man, especially some fresh words, could only be understood by Wang Junlin, and everyone else felt as if they were listening to a book from heaven.
