Lonely House......

Lan Nuo fell on the bed, when he went, he flew over, and when he came back, he naturally flew back, Lan Nuo said that before he learned to fly, he never wanted to go to the sky again, it was too uncomfortable.

Lan Nuo, who fell on the bed, opened the street group, although this group of street fighters is not called a brick beast, but there are many more studies on crossing than ordinary people, and the effect is obviously better if they don't understand it.

It's really hard to come up with a name: "Does anyone know how to make a gun after crossing over?" ”

Salted fish looking up at the starry sky: "I won't be sleepy if you say this!" ”

Salted fish looking up at the starry sky uploaded a .docx for making a musket

Salted fish looking up at the starry sky: "The fire gate gun is the prototype of the gun, this is the simplest, and the protagonist can start from this." ”

Lan Nuo looked at it, the musket was not even as good as the arquebus, and the flintlock pistol in his design was the least advanced than the arquebus, and he didn't want to use something so backward at all.

It's really hard to choose a name: "This is too inferior, is there a more advanced one, can the flintlock pistol be successful?" ”

Salted fish looking up at the starry sky: "If you don't think about logic, it's not impossible, after all, readers don't pay attention to these."

But if it really crosses, the flintlock pistol is really unreliable, let me tell you so! The ancient steelmaking technology was not good, and raw wrought iron was not suitable for making gun barrels, and even if there was qualified steel, drilling was a big trouble.

This thing is not a joke, if it is not strong and blows up, it will collapse itself before killing anyone. There is also the spring of the flintlock pistol, this thing needs spring steel, I know the formula of spring steel, but this thing needs to be processed to the same standard, with the ancient process, the error can be reduced to one millimeter, you will burn high incense! ”

Lan Nuo saw it, and immediately deflated, but the cows had already been blown out, wouldn't it be very embarrassing if he couldn't get something......

It's hard to pick a name: "That...... I opened another hang for the protagonist.,The first soul skill,Cross-border distribution,You can express things from the real side.。 ”

Lan Nuo talked about the effect of his first soul technique.

It's really hard to choose a name: "Everyone help me see, with this hanging, what kind of gun can be made?" ”

Yin Xiaoyu: "This one is so good!" I wanted to remind you yesterday that your brain hole is really good, but it's not big enough, and no one will look at it if it's not cool enough! ”

Tao Hexagram Immortal Master: "There is this hanging, not to mention the flintlock pistol, AK can also be made!" ”

Salted fish looking up at the starry sky: "It's not that simple, the main thing is precision, the soul power of the protagonist must not be a big guy like a machine tool, processing accuracy is always a problem, so, you wait for me, I'll make a list for you." ”

Sakura: "Stop! Salted fish! People write novels, don't they really cross over! ”

Salted fish looking up at the starry sky uploaded a .txt of crossing the purchase list

Grabbing the root treasure: "It's over, the salted fish has started again!" ”

……

Lan Nuo silently downloaded the purchase list, which was a good thing for him, and after a good night's sleep to recover from the experience, he asked Dugu Bo for a family blacksmith shop, the blacksmith shop was very simple, and there were no tools except pliers, anvils, and sledgehammers.

The blacksmith went home to rest temporarily because of Lan Nuo's request, and in the past three days, no one was allowed to enter the blacksmith shop except him, and even the curious Dugu Yan was stopped outside.

Lannuo is tinkering in it alone, and there are many things that can be bought on the Internet, from the most basic, pliers, files, vernier calipers, to advanced hand-cranked stamping machines, and small machine tools.

Some people buy parts when they can't be shipped at once, and then assemble them, but fortunately, Lannuo has experienced metalworking internships, so I still have some understanding of the use of these things.

Three days later......

Wen Xi, the best blacksmith of the Dugu family, returned to his blacksmith shop indignantly, he was a senior blacksmith certified by the blacksmith association, and even learned from the blacksmiths of Haotian Sect, and the family handed over his blacksmith shop to a nine-year-old hairy boy to take care of for no reason, and asked him to cooperate with the other party.

This is simply an insult to him, but he is just a blacksmith, the status of the blacksmith association on the mainland is indeed not low, but it is only not low, compared to the Wuhun Hall that represents the soul master, the blacksmith is just a profession with average treatment, and he can't resist the orders of the family master.

Vincy was furious when he saw that his blacksmith had been greatly changed by Lanno, who was on his workbench, polishing something with a file, very attentive.

Vincy wanted to take advantage of Lan Nuo's inattention to give him a hard blow on the back of the head, but the head of the family repeatedly told Lan Nuo about the importance of it, so he had to give up his unrealistic idea.

Seeing the file in Lan Nuo's hand, Vincy was stunned for a moment, the uniform texture on the file was extremely smooth, compared to the file he used, I don't know how much better, more importantly, the file was very hard, even if it was polished steel, there was no wear and tear, he admitted that this file was indeed a good thing, but looking at Lan Nuo's unfamiliar methods, he knew that he was a layman.

Vincy saw two polished and polished parts on the workbench, and his professional habit made him pick up the two parts and compare them, and with the naked eye, he couldn't even see the difference between the two, as if they had been copied.

Vincy found it hard to believe that these two identical parts were actually polished by the unfamiliar teenager in front of him.

At this time, Lannuo took out the vernier caliper and measured the parts that were being polished.

"Tsk! Failed again! It shouldn't be! The equipment is fine! Why is it crooked again! ”

"What failed?" Vincy's voice startled Lan Nuo, and when he turned around, he saw that there was another person behind him.

"You're Vincy's senior!" Lan Nuo patted his chest and pushed the parts in his hand to Vincy: "I want to polish two parts of the same specification, but they are always polished. ”

Vincy took the parts, compared them with the first two, and frowned: "Isn't this the same?" How did it fail? ”

"My goal is to have an error of 0.1 millimeter, but this one is at least 0.3 millimeters." Lan Nuo was a little discouraged, and when he really started to do it, he realized that it was not so easy to build a gun.

"Millimeters? What is that? Vincy was confused.

"A unit of measurement." Lan Nuo took out the vernier caliper: "This is one millimeter, and one-tenth of this is a tenths of a millimeter." ”

"Tenths of a millimeter? How can it be? No one can control the error so small! Wait a minute! You say that the error is only 0.3 millimeters! Vincy found the crux of the matter.

"About 0.3 millimeters, I'm not sure either."

"How did you do it!" Vincy asked excitedly: "Your polishing action is so rusty, how is it possible?" I'm not saying you can't...... It's just that I've never seen anyone do it to this extent! ”

The excited Vinci was already a little incoherent, he had ever seen the strongest blacksmith who couldn't do Lanno's accuracy, and he desperately wanted to know how Lanno did it.
