Blacksmith Feng originally thought that Qin Hao was just playing a few small tubes, but when he got the drawings, he was dumbfounded, the steel cylinder Qin Hao wanted was not only large, but also thick, and the most important thing was that it was smooth inside. Pen ~ fun ~ pavilion www.biquge.info

Here, Qin Hao didn't plan to do rifling, after all, in this era of emphasizing literature and ignoring martial arts, when his strength arrived, Qin Hao didn't want to show his ability to defy the sky.

He has to keep some back hands for himself, it's not that he underestimates Fang La, Fang La's rebel army really doesn't need that kind of anti-heaven thing, what kind of people to fight, what kind of weapons to use, every step, Qin Hao has to think about it!

lest you not play to death others, but be played to death by others!

Although this thing looked extremely simple, Blacksmith Feng felt quite embarrassed, "General Qin, your steel cylinder is not built, but cast, before you do it, you need to make a mold first, this process is probably a bit laborious." ”

China's handicraft industry has always been relatively developed, and a long time ago it created a traditional casting process with China's national characteristics, among which clay casting, iron casting and solution mold casting are the three major casting technologies commonly used in ancient times.

Although Blacksmith Feng didn't know what Qin Hao wanted to build such a thing, he knew what kind of method to use when he looked at his drawings, which may be the wisdom of the working people, which will always be so endless.

Qin Hao saw that he could get to the point as soon as he opened his mouth, and knew that he had found the right person, although he also knew how to make these molds, and even did better than them, but it was very time-consuming and laborious to do it himself.

Therefore, handing over some heavy work to people who are not so professional to do it and reduce his burden is Qin Hao's best choice now, and it is also the only choice.

Although the results may not meet their expectations, but thinking about our ancestors, if they hollowed out the elm, they could make the elm cannon that made the little Japan dare not come out of the turret, Qin Hao felt that his conditions were really much better than our ancestors.

"Master Feng, you don't need to say anything, just do it, as for the price, you don't have to think about it, I'll give you three times the salary!"

Qin Hao said very simply, his own earthen cannon is definitely epoch-making, although the earthen cannon can kill people, it can also save people, so the price is not a problem for him at all, the problem is to be fast!

"Triple the price?"

Blacksmith Feng said that he was old, his ears were a little back, and he didn't hear clearly, and it wasn't until Qin Hao put thirty taels of silver in front of them as a deposit that he was sure that this matter was true.

"General Qin, rest assured, I promise to build ten such steel cylinders within half a month!"

The problem that can be solved with money is not a problem, Qin Hao saw that he answered very simply, knowing that this master wanted to mobilize other blacksmiths to participate in this matter, even if he paid others double the salary, then he still had to earn, why not do it?

Qin Hao nodded, did not stay in the blacksmith shop for a long time, but returned to the barracks, Liang Hongyu and Liu Xiang'er took the villagers to Dusongguan to shout, the whole barracks seemed a little deserted, only occasionally heard a deafening explosion from the training ground.

That's Mao Xue improving gunpowder, of course, the formula is also Qin Hao's, what Mao Xue has to do is to make and verify, listen to the sound, the effect should be good, "Huzi, go and call Mao Xue, I still have a drawing to hand over to him!" ”

Not long after Huzi went out, he led the gray-faced Mao Xue into the study, Qin Hao picked up a few sketches from the desk, handed them to Mao Xue and said, "You take a look first, is there anything you don't understand here!" ”

The sketch is very simple, it is a simple gun carriage, which can be pulled to walk with the cannon, and the height of the muzzle can also be adjusted, as for whether the gun can rotate, its process is relatively complicated, and the recoil problem when the gun is fired must be considered, Qin Hao did not test the filter.

Although the sketch is simple, Mao Xue looked at it very carefully, for fear of missing some places and not meeting Qin Hao's requirements, a sketch, he looked at it for half an hour, and then said: "There is no problem with making this artillery mount, but this cannonball ......"

This cannonball, which I am sure I have never seen before, looks like a winter melon with a long tail trailing behind it.

Qin Hao said: "This cannonball is actually very simple to make, it is a round iron ball, which is filled with gunpowder, and this tail is a fuse, when the cannonball is pushed out in the barrel, this fuse is ignited, and it only explodes after it is shot!" ”

The principle of making earth cannons is actually not complicated, and its principle is very similar to the two-kick kick we played when we were children, but in the era of snow, let alone two-kick kicking, even one-foot kicking has never been heard.

After thinking hard for a long time, there were still doubts in my heart, and I was worried:

"It's just that after this fuse catches fire, if it hits far, the shell will explode in the air, if it hits close, it won't explode for half a day, what if it is picked up by the other party's people, and then thrown back with a stone thrower?"

When Qin Hao heard this, he really wanted to kick him over, a seemingly smart head, but it was so strange when he thought of the problem.

Just wanted to say a few words to him, Tian Xiaoqian was already laughing on the side: "If you hit close, don't you know how to cut off the fuse?" ”

"What you said seems to be right, so be it, Childe, I'll take the sketch back first, take a good look, make the fuse first, and see how much time it takes to burn each time." Mao Xue scratched his head, and suddenly Tian Xiaoqian said something reasonable.

Now that he has figured it out, Qin Hao didn't bother to bother to talk to him about the principles of combustion and explosion, for people like Mao Xue, it is good to be able to understand these principles, it doesn't matter if they don't understand it, just do it.

"You have to hurry up about this matter, half a month later, we will start assembling and verifying this artillery, although the military spirit of Dusong Pass is unstable, but we want to take him down, it really can't be done without this thing!"

Mao Xue knew that Dusong Pass was a natural danger, not to mention that there were 100,000 people stationed on the pass, that is, hundreds of people were stationed, as long as the other party worked together, it would not be so easy for us to take Dusong Pass.

The power of the artillery, when he was in the Feishan camp in the snow before, not only saw it, but also made it himself, but in his impression, it seems that the power is not great, and it is not as effective as the stone throwing machine that has been passed down for thousands of years.

Although Mao Xue had some doubts in his heart, as long as it was something Qin Hao confessed, he would do it seriously, and he would do it well, "Childe, rest assured, within half a month, Mao Xue will definitely make a cannon carriage and shells that will satisfy you!" ”

Qin Hao nodded, he didn't have the slightest doubt about Mao Xue's words, just like when he handed over the gunpowder formula to him, Mao Xue was preparing and verifying it there day and night, which made Qin Hao feel a little distressed.

After leaving in the snow, Tian Xiaoqian said: "The production of this artillery looks very complicated, give him half a month, will it be too short?" ”

Qin Hao shook his head and said: "For you, it may be too short, but for Mao Xue, he already has the foundation in this area, according to my estimate, he can complete it in about ten days, but seeing that he is too tired during this time, he only gave him half a month's period!" ”

Tian Xiaoqian understands Qin Hao's good intentions, but she also understands Mao Xue and others, as long as it is something that Qin Hao explains, even if they fight for their lives, they will complete it as soon as possible.

Unless they are locked in the house, it is estimated that they will be allowed to rest.
