In the east of Qianzi Town, a large open space was granted to Lu Yun. At this time, the entire clearing was a busy scene, which could be said to be in full swing.

In the past two days, the general mobilization of the war has begun within the sect, and all the people are preparing to fight the demon clan at that time, and Lu Yun's side, as the arms maker appointed by Feiyunzi, the town specially arranged a large number of people for him.

It's no wonder that Feiyunzi cares so much about this matter, just the improvised artillery that Lu Yun made can play a huge role in the war.

And the later improvements......

God knows what other good things Lu Yun can come up with.

Of course, airplanes, ships, cannons, etc., will be useless for a while, even if Lu Yun has a full set of basic theories of the earth, and the materials and standardization alone will not meet the standards.

Not to mention anything else, screws are not a big thing, but they are very important-now the cultivation realm can't be mass-produced.

However, Lu Yun naturally couldn't sit there and wait, he just needed to come up with a standardized prototype and assembly line first.

The assembly line is very important, which is the basis of standardized industry, and the other basis is the steam engine.

"Good boy," Elder Huoyun looked at the big flying cauldron that Lu Yun was busy working on, and then looked at the factory building that was being built urgently, and said, "How long will this cauldron take?" ”

When Elder Huoyun said how long, he was actually referring to mass production.

After all, although this big flying pot can be installed, but there is only one, and the effect is too small.

But if the energy is ......

If nothing else, at least the delivery of grain can be a hundred times easier.

In the past, there was a large-scale war in the Xiuzhen Realm, and the transportation of grain and grass mainly relied on flying swords, but after all, that thing was flat and not much loaded, so it was not particularly practical.

But this big flying cauldron is different, one pot is pulled up, and the amount of ten flying swords is topped.

"Soon," Lu Yun said while holding a hose in his mouth, and said while smearing glue on the already cut spirit stone chips, "Now it's almost like gluing this battery and connecting it with a array." ”

After he learned the large-scale energy storage array from Mr. Lan Ya before, he improved it a little by himself.

It's not that he directly modifies the formation diagram, after all, he doesn't have that much ability now, but it's no problem to improve the usage.

The overall idea is actually similar to that of new energy vehicles on the earth, that is, to adopt the idea of stacking, and glue together almost 100 pieces of spirit stone chips carved with large energy storage arrays to form an energy storage array, and then connect them to the big flying pot.

In this way, the big flying pot can have a more durable flight ability.

"Okay!" After gluing the last piece of spirit stone, Lu Yun jumped onto the big flying cauldron: "Let's try it this time." ”

His hand pressed on the spiritual connection array diagram of the big flying cauldron, and soon Lu Yun was able to control this big flying cauldron, and then flew on this field for a while, and glanced at the energy display on the big flying cauldron: "It's not bad, this time the energy is much more sufficient!" ”

This energy display was made by Lu Yun after moving the array diagram on the spiritual power test stone, not to mention, although it is slightly different from the display icon in the mobile phone on the earth, but the overall function is basically the same.

In other words, it is clear at a glance how much energy is left in this big flying cauldron.

He had just flown for nearly twenty minutes, and he had only consumed about two percent of his energy.

In this way, this big flying pot has been flying for more than ten hours, and it is not a problem.

"That's good, that's good," Elder Huoyun nodded on the side and said, "With this, our material delivery will not be worried." By the way, good boy, since this big flying cauldron is almost done, the artillery ......"

Elder Huoyun is most concerned about artillery right now.

That's the point, the main thing is fun......

Lu Yun jumped down from the big flying pot and said, "The artillery can only make a sample first, and if you want to mass produce it, you still have to wait for this assembly line to be ready." We can make a decision now after the transformation. ”

Huoyun nodded violently: "That's okay!" Let's get an improved one first, by the way, apprentice, you have researched this improvised artillery, and you will give it a name? ”

Everything has to have a name.

For example, what AK47 on the earth, DF41, and so on.

Naturally, it is no exception here, and it is difficult to distinguish between no names.

"I've thought about it a long time ago," Lu Yun raised his eyebrows with a smile: "This simple artillery, let's call it German Artillery No. 1, I think this name is great." ”

"German Cannon One?" Elder Huoyun was curious, "Why is this called?" ”

Lu Yun snapped and gave a thumbs up: "We want to convince people with virtue!" ”

Huoyun: "......"

"That's a good name!"

Well, it is great to convince people with virtue.

According to Lu Yun's thoughts, the size of this German cannon is not easy to move for the time being, and it can only be large and not small.

In the current cultivation world, there is no standardized and programmed steelmaking yet, and the small musket does not mean that the cannon can be reduced, for example, the main material of the German Cannon No. 1 in Lu Yun's hand is almost cast iron, with a carbon content of more than 2%, and the biggest advantage of cast iron is that it is simple to form, and the volume is not limited.

However, although the hardness of cast iron is similar to that of steel, the fracture energy is much smaller, which refers to the energy that the material is able to absorb under impact.

As long as the mold is designed, no matter how large the cannon is, it is theoretically possible to cast and splic, but the range of the cannon is closely related to the chamber pressure, if the range is long, the power is large, it is necessary to increase the chamber pressure, so if you want to make the cannon bigger, you must have a very thick and thick chamber wall, even so there is an occasional problem of exploding.

As for getting a sniper rifle or something......

Don't think about it for now.

"So the next thing we're going to do is the question of the bullet?" Elder Huoyun had really used this German Cannon No. 1, and in his opinion, this thing was good for everything, but it was too troublesome to load, and the speed couldn't be fast.

Lu Yun nodded and said, "By the way, in fact, there is a good way to bomb this thing, but that is mainly the transformation of bullets, and we can't make it now." ”

"Still not good?" Elder Huoyun said anxiously, "Is it still in standardization?" ”

Lu Yun shrugged his shoulders helplessly: "It's not just standardization, but also materials, formations, labor, and machinery. ”

Huoyun: "......"

"Same as the same!" Elder Huoyun ran away in an instant, and after a while, he ran back with a big box in his hand, and poured the box to the ground, and it fell to the ground with a bang, and there were a lot of metals, jade, stones, wood, and other materials in it! Elder Huoyun said anxiously: "Good man, these are some of the materials I have collected, there are everything, you see which one is easy to use, let's solve the material problem first and then study the others!" ”

Lu Yun: "!! ”

As a cheap master, there are really a lot of good things in his hands!
