Lan Nuo could see the curiosity that belonged to the craftsman in Vincy's eyes, he didn't think about ridicule or slap in the face, in his previous life, his country was able to rise from nothing because of such a group of craftsmen from a big country, so he still had a lot of respect for such people.

"It doesn't have to be so, my technique is really rusty, I have a specialization, I'm good at using my brain, I don't have any precision in my hands, in fact, it's not difficult, you see this is a pliers, the workpiece will not shake if it is fixed on it, and then ......"

Lan Nuo introduced the role of these equipment to Vincy in the same way, and Vincy also carefully recorded that these things, for blacksmiths, were simply artifact-like things.

The most important thing is that after Lan Nuo disassembles these things one by one, Vincy is confident that he can use these equipment to replicate a set of equipment that is exactly the same or even more accurate.

He also understood why Lan Nuo's clumsy technique could still control the error so small, and he was confident that he could do better.

"I probably understand, these are indeed genius inventions, and the profession of blacksmith will be rewritten because of you! If it weren't for the need for secrecy, your invention would be enough to give you a seat as an elder in the Blacksmiths' Guild! Vincy said excitedly.

Lan Nuo scratched his head embarrassedly, these were all brought by him from the earth, and they were said to be his inventions, and he really deserved it.

"Tell me the specifications of the parts you want, and I'll try them!"

When Lanno heard this, he told Vincy the size of the parts and taught him how to use vernier calipers, which made him start to do it.

I have to say that the professional is different, although Vincy used to polish it all by feeling, but the foundation is there, and he is much more skilled than Lan Nuo.

After a while, a rough part was polished, and Lanno excitedly took the part for measurement.

"The error is less than 0.1 millimeter! Vernier calipers can't even measure the error! It's your first time trying, can an ordinary blacksmith do this? ”

"It should be possible, as long as you practice, more than ninety percent of blacksmiths can do it. I'm just trying it for the first time, and I'm sure I can narrow it down even further after that. ”

Vincy's answer overjoyed Lanno: "Perfect! Now the musket has a play! Come! These are the parts I need, can you do it all with that precision? ”

"No problem! Leave it to me! ”

……

In Lannuo's design drawing, most of the parts can be produced locally by Douluo, such as springs, which are not very expensive to purchase from the earth for the time being, and the only more expensive is the barrel.

The special steel on Douluo's side can also make gun barrels, but the kind of things forged by high-level blacksmiths can easily cost dozens or hundreds of gold soul coins, which is too expensive.

It is better to buy a ready-made steel pipe from the earth, which is only a dozen yuan a piece, and it is still strong and durable, and it will definitely not blow up.

Handing over the parts to Vincy, Lanno began to work on bullets, at first he was going to use paper shell bullets, but later found that paper was not easy to handle, so it was better to use metal bullet cases directly.

As we all know, the bullet of the breech gun is divided into a bullet head and a cartridge case, and there is a primer and gunpowder in the cartridge case, and everyone knows the ratio of gunpowder, one sulfur, two nitrate and three charcoal, sulfur and charcoal are easy to get, saltpeter is a little troublesome, the nobles use this thing to make ice, and they can barely buy it on the market, and the amount will be used in the future, so I am afraid that I will have to go to the toilet to scrape the nitrate.

It is not difficult to use smokeless gunpowder in bullets, sulfuric acid, nitric acid, and cotton are synthesized into nitrocellulose, which is more than enough as old-fashioned rifle gunpowder.

As for the primer that can make the bullet hit and detonate, it is another substance, called mercury thunderate, with alcohol, nitric acid, mercury, you can make this thing, but the reaction is a bit dangerous, easy to fry, anyway, make a formula, in the future, you don't need to make the bullet yourself, the manufacturing process is slowly improved by the craftsman.

The primer, gunpowder, warhead, and cartridge casing are assembled together by hand, and bullets of the same specification are born in Lanno's hands, and the brass cartridge casings reflect sunlight and give people a visual sense of violent aesthetics.

There are only more than 20 bullets in the first batch, after all, they are only experimental products, there is no need for too many, and if the effect is not good, the design scheme will have to be changed.

Another three days passed......

Vincy watched as Lanno assembled the parts he had polished one by one, first a flintlock pistol with a relatively simple structure was born in his hands, followed by a second breech gun with a relatively complex structure.

Seeing the parts born in his hands come to life and put them together, Vincy had to admit that Lanno's design was too genius, and the specifications of each part were exactly the same, and the tight fit was full of mechanical beauty.

Lan Nuo is very satisfied with Vincy's craftsmanship, his breech gun is designed to be a manual shell throwing type, which is very close to the modern mainstream firearms, as much as possible to strengthen the air tightness of the rifle, if the accuracy of the parts is not good, it will seriously affect the shooting accuracy, and may also leak air to hurt the shooter's eyes, but at present it seems that the accuracy is higher than the design.

As for why Lan Nuo didn't get a semi-automatic rifle or an assault rifle, the reason is very simple, the manually produced bullets are really unbearable, and the assault rifle bursts down with a shuttle, and a dozen rounds of ammunition are gone, and the firepower is really strong, but it can't afford to use it!

It's better to strengthen accuracy and range, similar to Mosin Nagant, 98K This bolt-action rifle, even if it is placed in modern times, can also be used as a sniper rifle, the effective combat radius of the soul master is generally not more than 100 meters, and this thing is 500 meters away, plus a scope, there is a great probability of headshots.

A sniper, the threat in the battlefield is self-evident, plus this kind of rifle with a long barrel is generally more powerful, and it overflows 100% damage to ordinary people, which can be used to deal with the soul master, even if it is a soul sect, if it is not a defense system, it is likely to be unable to carry it, which still refers to a situation of being prepared.

As for the defenseless situation, there is little point in discussing this, if there is no defense, Title Douluo may be shot in the head, after all, people will die if they are killed, and not all soul masters have head soul bones to increase the defense of the braincase.

It doesn't make much sense because the soul master above the fourth ring already has a strong sixth sense, and even if he can't find himself targeted, he will have a premonition of danger at the moment when the bullet is discharged.

Lan Nuo stroked the two guns, very satisfied, the front-loading flintlock pistol is low in cost, simple in structure, easy to mass-produce, and can pull up an army with strong combat effectiveness in a short time.

The rear-loading bolt-action rifle has great power, long range, and easy operation, and can be used as a high-end product.

Lanno can't wait to try out the power of the two guns!
