"Is that still *?" Luo Heng asked excitedly.

"Yes, but it's something that the Magician Chambers sell, and it's expensive. Harding spoke.

"Magic Chamber of Commerce, dwarf...... We dwarves can't make it?" Luo Heng asked in astonishment.

"That's made by an alchemist, hurry, don't bother me. Harding was getting impatient.

Luo Heng was stunned with the selected materials, copper, fine iron, all of them, Luo Heng ran a few times to get things ready, and began to ponder this musket.

After reading it carefully, Luo Heng had a bottom in his heart, on the one hand, the barrel forging was unqualified, how to say it, the caliber is different, it seems to be hand-forged.

The second is that there is no rifling and the barrel is too long.

Although the longer the barrel, the longer the range, the greater the pressure, and in the era of bullets, the pressure will be borne by the bullet, and in addition, the manufacturing process of the barrel has been perfected, and even so, after how many rounds of bullets, the barrel needs to be replaced.

Then there is the problem of air tightness, * The air tightness of the weapon is the reason for the greatest range, the barrel cannot be said to be as large as the projectile, after the barrel is worn, it is impossible to say that the projectile is remade, and such a small gap is impossible just by casting.

*Recipe. "Luo Heng knows the * formula, but the artillery needs the * formula, but the simple artillery, * and * are not much different.

However, it is a little particular about the production, * can be made into granules, there are gaps, increase the air expansion ~ expansion speed when burning, of course, smokeless * is better, but smokeless flame needs some chemical things, and it is unrealistic in a short time.

When Luo Heng was studying artillery, the three carpenters were in full swing, because they still managed to eat food here, and they also ate meat, you must know that there are not many opportunities for carpenters to eat meat.

is more motivated, just one day, Aisen, Lake made the impeller, Luo Heng pointed to polish it smooth, and the thickness was also consistent, of course, this is not particularly big for things like blowers.

As for the bearing, Luo Heng found that it was a little difficult to manufacture, so he put it aside for the time being, and directly rubbed it against each other with metal, first to see the effect for Sadinia, and then he would support his own actions, and the artillery thing should be taken out and used, Luo Heng alone could not be said to be taken seriously, but Sardinia was different.

When eating the next day, Luo Heng opened his mouth and said, "Teacher Sardinia, I found someone to make a blower that can quickly increase the temperature of the flame. ”

"The three carpenters you were looking for?" asked Satin as he ate the meat.

"Yes, I want to install it on your stove, teacher, and try it. Luo Heng said.

"Cheney, don't fool around, delay the teacher's time, it's fatal. Aden heard Luo Heng call Teacher Satin in his heart, and he was dissatisfied, so he spoke.

"That's it, Cheney, don't mess around, you might as well work with Harding. Lordeen also spoke.

Harding looked at Satin expectantly, it was too much, Satin glanced at everyone, and said, "Cheney, I can give you a chance, but if it doesn't work, you have to work with Harding." ”

"Yes. When Luo Heng heard Satin say this, he immediately nodded in agreement.

Then Luo Heng couldn't care about eating, so he hurriedly ran over to find the three carpenters and carried the assembled blower with a diameter of two meters

Luo Heng took off the compressed bellows interface again, which Luo Heng had already prepared, the size of the outlet of the blower was about the same as the size of the inlet of the original bellows.

Command the three carpenters to install and fix the blower, and as for the location of the interface, just wipe it with wet ~ moist soil.

Harding and the others looked at the wooden blower, and they all shook their heads, even Satin was the same, you must know that the compressed bellows are three meters high, two meters wide, and four meters long, and that kind of bellows is like an air bag.

The furnace uses charcoal, which has a better temperature, but it is never as hot as coal, but Luo Heng has not found coal yet.

When Eisen's three carpenters saw Satin, they all nodded, and Sardin himself lit the fire, and then Eisen began to stir the blower.

Whew, hoohoo!

With the blower running, and it didn't need to be too fast, the charcoal inside the stove quickly burned, and the furnace spewed out a blue flame of tens of rice grains.

"It's ....... "Everyone was stunned.

And the dwarf who had pressed the blower for Satin pushed Eisen away and then learned to shake it.

"It's so lightweight. "Sodin is for Satin, the kind of airbag bellows that are pressed up and down, and there is an elastic structure in it, so you have to use force when you press down, and now this one hardly requires much force.

Satin pushed Suodin away again, and then used it, looking at Luo Heng differently.

"Alright, alright, Cheney, you've done a good job, it's a great invention of our dwarves. Satin looked at the fire and knew that the temperature was very high, and couldn't help but admire.

"Teacher, in fact, this can be improved, the fan blades in this can be made of copper skin, and the handle can be extended, so that two ordinary humans can blow the wind, and we dwarves don't need to blow the wind themselves. Luo Heng took the opportunity to say.

"You're in charge of this, you need a coppersmith, you need people to do it, and I need every stove here to be installed ....... When Sardin heard this, he looked like a word, and this wood was not very high.

"Yes, teacher, teacher, I want to do something else, I want some materials. Luo Heng took the opportunity to say.

"Go find it yourself, little ones, and start doing it. Satin shouted, and Thordin found a piece of wood, and sat on it, shaking the handle of the blower, and looking at the other bellows dwarves.

"Cheney, Cheney, how about getting me a blower first?" And Luo Heng's side was surrounded by dwarves, because everyone saw with their own eyes that the fine iron that needed to be forged was put in, and it was almost about to soften after a while, you must know that the higher the temperature, the faster the forging speed, and the less effort it can be forged.

"No problem, as long as there are enough people, I will equip all the stoves with all-copper blowers in two days. Luo Heng patted his chest and reassured.

In fact, copper is better to make, and the coppersmith craftsmanship of this period is very exquisite, as for the source of copper, please, there are dozens of blowers, and the copper of the entire fortress must not be needed.

So the northern fortresses suffered, first the coppersmiths, who were requisitioned, and then the bronzes of the families, which were also looted.

One of the three Aisen is responsible for being the boss of a group of coppersmiths, directing these coppersmiths to work, more than 30 coppersmiths, occupying several caves, some of which are responsible for building wind wheels, and some of them are responsible for building shells, and this kind of blower can be used by two people, and Luo Heng increased the diameter of the friction part, and used animal fat to moisten ~ slip.

"Haha, we dwarves are the smartest. In the evening, Satin laughed, and the other dwarves looked at Luo Heng with resentment.

Sodin was even more proud, this guy sat there all day, so leisurely.

"Today I basically forged a whole set of plate armor, haha. Sardinia said his success today, you must know that plate armor is not easy to forge, to burn constantly, forging, but with today's furnace, although the fuel consumption is twice as much, but how cool it is to forge it yourself, put two pieces of plate armor material into it at the same time, and almost never stop forging, Sardin feels that it has never been so cool today, and the temperature is high, the forging material is burned soft, a few hammers, it is formed, and then folded several times, each forging is folded twice more than before, and the interval is shorter。

"Teacher, I can give you a safety copper blower tomorrow, so that the forging capacity of our Dwarven Chamber of Commerce will be increased by at least four times. Luo Heng hurriedly said.

"That's it, all the forging furnaces are turned on, the personnel are doubled, the forging speed is doubled, haha. Satin laughed, you must know that the Dwarven Chamber of Commerce also makes money, and what the output represents, it means money.

That night, Luo Heng did not rest, commanding the blower that had already produced the finished product and placing it on the forging furnace, while some anxious forgers did not sleep at all, and insisted that Luo Heng place it for himself first.

As for steam forging or something, Luo Heng didn't dare to take it out, and took it out and Sardin specified that he would smash Luo Heng's head, because dwarves rely on forging to eat, and you smashed the dwarves' rice bowls, tsk.

So not everything can be taken out, of course, if you return to the dwarf kingdom, Luo Heng may be able to take it out, after all, it needs to be kept secret.

The production of the blower doesn't need Luo Heng to worry much, Luo Heng has heard that there is coal, but it is said that it is poisonous, so it is generally not used.

Of course, Luo Heng knew how different the temperature of charcoal was from the temperature of coke.

The enclosed cave is indeed not suitable for burning coal, but the sub-mother cannon does not need coal either.

The next night, Luo Heng found Sardin alone: "Teacher, I have something I want to make, which is a war machine in an ancient blueprint that our tribe obtained before. ”

"What, ancient war machines. Satin was taken aback, and suddenly stood in front of Luo Heng.

"Yes, there is this that can resist the attacks of the orcs. "Luo Heng is talking nonsense, but there are many ancient legends in this world.

"A magic weapon?" asked Satin with some excitement.

"No, it's the forged weapon of our dwarves. Luo Heng immediately stood up, as a dwarf, he must have a dwarf position, a magic weapon, which is a thing of the Magic Guild.

"What do you need?" asked Sardin.

"I want to send Hans and Lake and Eisen and the coppersmiths to the Dwarven Chamber of Commerce, and you know that once this blower is obtained by the human rubbish blacksmiths, our Dwarven Chamber of Commerce will ...... in the future. "Luo Hengcai doesn't care about what humans are not human, he is now a dwarf, and in Luo Heng's opinion, two meters and five meters tall should be giants, not humans like himself, farts ~ shares determine the head, that's it.

"Don't worry, it's easy for anyone here to get in, but it's hard to get out. Sardin glanced at Luo Heng and said, the meaning was obvious, he had already done it.

"The teacher is wise. Luo Heng patted his ass once, it's really that the artillery is too sensitive, no matter who gets it, it's a threat, and knowledge is the biggest golden finger.
