Lan Nuo could see the craftsman-oriented desire in Wenxi's eyes. He did not think of ridicule or slap in the face. In his previous life, his country was able to take off from nothing because of such a group of craftsmen in his great power, so he still respected such people very much.

"No need to do this. My skills are indeed unfamiliar. I have specialties in my profession. I am good at using my brain. I don't have any accurate head on my hands. Actually, it's nothing difficult. Look at this, this is a clamp. If you fix the workpiece on it, you won't shake, and then..."

Lan Nuo introduced the functions of these equipment to Vinci, and Vinci also carefully recorded that these things were simply artifacts for blacksmiths.

The most important thing is that after Lan Nuo disassembled these things one by one, Vinci was confident that he would use these equipment to copy a set of equipment that was exactly the same or even more accurate.

He also understood why Lan Nuo's clumsy technique could still control the error so small. If he had done it, he would have the confidence to do better.

"I probably understand that you are indeed inventions of geniuses. The profession of blacksmith will be rewritten because of you! If it is not necessary to keep it confidential, your invention is enough to allow you to have an elder seat in the Blacksmith Association!" Vinci said excitedly.

Lan Nuo scratched his head embarrassedly. These were all brought by him from the earth, and it was said to be his invention, which he really deserved.

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

When Lan Nuo heard this, he told Vinci the size of the parts and taught him how to use a vernier caliper, which made him start to do it.

I have to say that professionals are different. Although Vinci used to polish it all by feeling, the basics were there, and he was much more skillful than Lan Nuo when he started to move.

After a while, a roughly processed part was polished, and Lan Nuo excitedly took the parts for measurement.

"The error is less than 0.1 millimeter! The vernier caliper cannot measure the error! This is your first time trying, can an ordinary blacksmith do this level?"

"It should be possible. As long as you practice, more than 90% of blacksmiths can do it. I'm just trying it for the first time, and I can definitely narrow the error further after that."

Vinci's answer made Lan Nuo overjoyed: "Perfect! The musket is here to go! Come on! These are the parts I need, can you keep them all in this accuracy?"

"No problem! Leave it to me!"

...

In Lannuo's design drawings, most of the parts can be produced locally by Douluo, such as springs. It is not expensive to purchase from the earth for the time being. The only more expensive one is the gun barrel.

The special steel in Douluo can also make gun barrels, but the things that are forged by high-level blacksmiths can often cost dozens or hundreds of golden soul coins, which is too expensive.

It’s better to buy ready-made steel pipes from the earth, which cost only a dozen yuan each, and they are sturdy and durable, and will never explode.

After handing the parts to Vinci, Lan Nuo started to make bullets. At first, he planned to use paper shell bullets, but later he found that the paper was not easy to work with, so it would be better to use metal shells directly.

As we all know, the bullets of breech guns are divided into bullets and shells, and there is base fire and gunpowder in the shells. Everyone knows the ratio of gunpowder. It is easy to deal with sulfide, 2000 charcoal, sulfur and charcoal, and saltpeter are a little more troublesome. The nobles use this thing to make ice, so they can barely buy it on the market. If the amount is used in the future, they will probably have to go to the toilet to scrape the salt.

It is not difficult to use smokeless gunpowder in bullets. Sulfuric acid, nitric acid, and cotton synthetic nitrified cotton, which is more than enough as an old-fashioned rifle gunpowder.

As for the base fire that can cause the bullet to hit and detonate, it is another substance called mercury lyric acid. It can be made by using alcohol, nitric acid, and mercury. The reaction is a bit dangerous and easy to explode. Anyway, the formula is made, and Lannuo does not need to make bullets himself in the future, and the manufacturing process will allow craftsmen to slowly improve it.

The base fire, gunpowder, bullets, and shells are manually assembled together. Bullets of the same specifications are born in Lan Nuo's hands. The brass shell reflects sunlight, giving people a violent aesthetic visual feeling.

The first batch of bullets was only more than twenty, after all, they were just test items, so there was no need to be too many. If the effect was not good, the design plan would be changed.

Three more days have passed...

Vinci watched Lan Nuo assemble his polished parts one by one. First, a flintlock rifle with a simple structure was born in his hands, followed closely behind, and a second breech gun with a relatively complex structure was also born in his hands.

Seeing the parts born in his hands put together as if they were coming alive, Vinci had to admit that Lan Nuo's design was so genius. The specifications of each part were not bad at all, and the tight stitching was full of mechanical beauty.

Lan Nuo is very satisfied with Vinci's craftsmanship. His breech gun is designed with a manual shell throwing type, which is very close to modern mainstream guns. It should strengthen the air tightness of the rifle as much as possible. 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. However, it seems that the accuracy is even higher than the design.

As for why Lan Nuo didn't use a semi-automatic rifle or assault rifle, the reason is very simple. The bullets produced manually are really unaffordable. If the assault rifle rushes down, more than a dozen bullets will be gone. The firepower is indeed strong, but it cannot be afforded!

It is better to strengthen the accuracy and range. A bolt-action rifle like Mosinnagan, 98K, can be used as a sniper rifle even in modern times. The effective combat radius of the soul master is generally no more than 100 meters, and if this thing is 500 meters away, adding a scope will have a considerable probability of headshot.

The threat of a sniper on the battlefield is self-evident. In addition, this kind of rifle with a long barrel is generally powerful, and it overflows 100% of the damage to ordinary people. It can be used to deal with soul masters. Even if it is a Soul Sect, if it is not a defense system, it is likely that it cannot withstand it. This still refers to being prepared.

As for the situation of being unprepared, it is not very meaningful to discuss this. Without being unprepared, the titled Douluo may be shot in the head. After all, people will die if they are killed. Not all soul masters have heads and soul bones that increase their brain defense.

It is not very meaningful because the soul masters above the fourth ring have a strong sixth sense. Even if they cannot find themselves aimed, they will have a premonition of danger at the moment when the bullet is out of the bore.

Lan Nuo stroked the two guns and was very satisfied. The front flintlock rifle was low in cost, simple in structure, easy to mass production, and could lead to a strong army in a short time.

The rear-mounted bolt-action rifle has a long range and is easy to operate. It can be used as a high-end product. The soul master of the fooling assistant and food department provides research funds to Lan Nuo.

Lan Nuo can't wait to try the power of two guns!
