On the way back, Sang Rou was puzzled and asked, "Brother-in-law, why do you use copper as a lid?" ”

Yuan Fang explained: "You know that gunpowder is flammable, right? A spark can ignite, and if a spark occurs due to friction when the lid is installed, the gunpowder will kill if it explodes, which is for safety. ”

Sang Rou suddenly realized: "Brother-in-law, you know so much. ”

Yuan Fang raised his eyebrows proudly, this is the inspiration he remembered a news he had read before, a gas leak in a residential building, many residents were trapped in the locked fire escape and couldn't get out, the fire brigade sent someone to smash the door lock with a sledgehammer after receiving the alarm, Yuan Fang was very puzzled at that time, and the firefighters were not afraid of sparks detonating the gas when the door lock was locked? Later, Yuan Fang learned that the fire brigade used a copper hammer, which would not produce sparks.

The problem that had been bothering him finally had a breakthrough, after breakfast, fatigue swept over like a mountain of seas, Yuan Fang hurriedly went back to the house to rest, and fell asleep.

Yuan Fang slept, Ye Qingru and Xia Yi stayed at home to protect Yuan Fang, and the rest of the people had to continue to work, Guan Xiaoyun and Hongyi went to the blacksmith furnace, Sang Rou took a nap and ran to the studio to continue making the fuse with Tian Erniu and them.

This sleep is called a fragrance, and when Yuan Fang woke up, it was already afternoon, he washed his face, took a steamed bun and walked to the blacksmith furnace while eating.

The blacksmiths were quite efficient, and in one morning they made a mold for the shots, and after several pours and a little polishing, they produced a sufficient number of them.

When Yuan Fang arrived at the blacksmith furnace, Guan Xiaoyun and Hongyi were driving the carriage out of it, and when they saw Yuan Fang coming, Guan Xiaoyun smiled and said, "Dean, you have finally woken up, the things have been ready, and I am about to send them to Sang Rou and them." ”

Yuan Fang was surprised and said, "It's done so quickly?" With that, he walked to the carriage and opened the box to see that it was filled with iron bullets the size of eggs.

Yuan Fang turned his head and asked the bearded blacksmith who greeted him: "How is that hollow bullet?" ”

The bearded blacksmith replied: "President, we have a lot of pig iron, but not brass, I have asked the Chamber of Commerce to send it quickly, and it is estimated that it will arrive in the middle of the night at the earliest, and the mold and taps here should be almost completed at that time, and the finished product is estimated to be early tomorrow morning." ”

Yuan Fang nodded: "Cheng, then it's hard for you, I'll let Damei give you processing money." ”

The bearded blacksmith smiled and said, "That's a good feeling, then thank you first." ”

Most of these blacksmiths were selected by Da Mei from the Plum Blossom Chamber of Commerce, and their craftsmanship was absolutely first-class, no worse than the blacksmiths in the military factory.

In the carriage on the table, Yuan Fang waved his hand and said, "Let's go, go directly to the beach." ”

The so-called beach is the place where the artillery is tested, the artillerymen are still playing with training, one cannon after another, the closer to the beach, the louder the sound, and then the horse pulling the cart was startled, Guan Xiaoyun took a lot of effort to pull the carriage, but the horse said that he would not go forward.

Yuan Fang couldn't lift a few large boxes of iron lumps, so they had to let Xia Yi go over to find someone to help, more than a dozen strong young men in a box, and it didn't take much effort to move the box next to an artillery, Yuan Fang was envious, and he was ashamed of himself.

Guan Xiaoyun went to deliver the carriage, and before leaving, he repeatedly asked Yuan Fang to wait for him to come back and try this new thing, and Yuan Fang agreed.

Guan Xiaoyun and Hongyi galloped all the way back to the carriage and then rushed back, and when they arrived at the beach, they were already out of breath, fortunately, Yuan Fang kept his promise and waited for them, otherwise Guan Xiaoyun would have scolded his mother.

Standing next to the artillery, Yuan Fang gestured to the artilleryman and said, "Hit there, yes, it's the stone with a hole in the body." The artilleryman was a little nervous, adjusted the muzzle of the gun again and again, and finally felt that it was almost enough to pick up the torch and look at Yuan Fang.

Yuan Fang was angry and said: "If you aim it, you will open fire, what do you think I am doing?" "The artilleryman's face is full of grievances, since Yuan Fang came, this goods has been pointing and talking here, which makes everyone a little unbearable.

With a bang, flames mixed with gunsmoke erupted from the muzzle, and the shell came out of its chamber, arcing in an arc and finally landing in a pile of stones two kilometers away.

Yuan Fang, who was holding the telescope, was surprised and said, "Damn, I actually hit, yes, you kid has a future." ”

The artilleryman was a little incredulous, picked up another telescope and looked at it, and then ran to the female soldier in charge of recording with joy on his face and said, "Write it down, add one more hit." "The selection of artillerymen is not over yet, and it is still unknown whether they can become the first batch of artillerymen, and the results of the test are an important reference for chasing, and the contestants are of course very concerned about the shooting results.

Yuan Fang was also happy for this artilleryman, and concluded: "The higher the elevation angle of the muzzle, the closer the landing point of the shell, on the contrary, the lower the elevation angle, the farther the shot, in fact, you can record the angle and landing point of each time you fire the cannon, which is a rule, as long as you can master this law, you will be a sharpshooter." ”

The artilleryman's eyes lit up when he heard this, and he saluted and said, "Yes, thank you Lord Yuan for your advice." ”

Yuan Fang waved his hand and said, "Okay, you take a break first, ponder what I said, and borrow this artillery for me first." ”

The artilleryman looked at the box that had just been moved and asked tentatively, "Lord Yuan, is there something new again?" Would you like to help? ”

Yuan Fang waved his hand and said, "No need, I'll do it myself, you, and you, all retreat away and retreat to a safe distance." Yuan Fang didn't know if the shotgun theory could succeed, and it was also safe to clear everyone just in case.

Guan Xiaoyun cleaned up the cannon chamber quickly, Yuan Fang loaded the gunpowder and fuze, this time, Yuan Fang deliberately picked the longest one.

Ye Qingru stuffed the cartridge butt into the barrel, and then asked Yuan Fang: "Brother-in-law, use this kind of small cannonball?" Yuan Fang nodded.

Xia Yi held one in one hand and asked, "How much to put in?" ”

Yuan Fang thought for a while and said, "Let's put ten first." Xia Yi and Hongyi moved together, put ten iron bullets into the barrel, Ye Qingru poked with a stopper, compacted the iron bullets, and then nodded to indicate that it was ready.

Yuan Fang took a deep breath, fine-tuned the muzzle of the cannon again, and said, "Okay, you all retreat, it's best to put up your shield." ”

Ye Qingru looked at the elder's fuse, nodded, and ran into the distance with Xia Yi, Hongyi, and Xiaoyun to set up a shield. Yuan Fang's fanfare attracted a lot of artillerymen who were waiting for the cannon in shifts to come and watch, and everyone gathered in groups to point and point, waiting expectantly.

Yuan Fang picked up the torch and lit the fuse, threw away the torch in the burning of the fuse, turned around and ran, and fled to Ye Qingru and them at a speed faster than a rabbit, hiding behind the shield, poking his head out and looking.
