Soldier A: "Take a look, take a look!!! Paper!! Pancreas!!! It's a barter for barter!!!!"
Soldier B: "Don't miss it if you're passing by!!! We only accept chicken, duck, fish, meat and eggs!!! They won't melt when exposed to water! You can replace them with soap that has been cleaned of oil and dirt!!!"
Soldier C: "Hurry up if you want to change!!! The batch has been changed today!!! I can only ask you early tomorrow!!! No money is required!!! Just chicken, duck, fish, meat and eggs!!!"
Yan Bing stood on the roof and looked at the group of shouting soldiers, nodded with a smirk, and then flew back home.
"Master!! Look!! What is this!!?? I just exchanged a pound of pork for it!! Pancreas that won't melt when exposed to water!! It's so useful!!" Fengchen held up the soap and came closer.
The old man came forward and said.
The old man stood up, grabbed the soap, looked at it, smelled it, and then threw it back to Feng Chen. He leaned back, shook his cattail leaf fan and spat out two words: "Prodigal!!"
The eldest brother was disappointed, then his face turned slightly red, and he had no choice but to go to the kitchen with the newly bought meat and vegetables...
Yan Bing smiled slightly.
It's okay, don't worry...
In the blink of an eye, it was noon, and Yan Bing was the first to rush into the kitchen as usual, served himself a bowl of rice, picked out a few of his favorite dishes, poured them into the bowl, and ran to the room with the bowl in his arms.
Although she was embarrassed squatting in the room holding a bowl of sea food while eating, she at least escaped from the scene before everyone came to the table and could retain some dignity for herself.
Yan Bing also gradually calmed down, eating and drinking when it was time to eat. After everyone had finished eating and the tables were cleared, she sneaked to Yingxianyuan while there was no one in the courtyard.
At this moment, the famous Dingguo Gong seemed to be a "transparent person" in her Dingguo Gong's mansion.
But only Yan Bing knows that all this patience will soon come to an end...
Today, the reason why she rushed to Yingxian Yin in such a hurry was mainly because the first batch of experimental subjects, the Whitworth magic modified rifle, was due for inspection...
Yan Bing has always been concerned about the research and development trends of these flintlock guns, and has been a participant from beginning to end, making suggestions.
Due to the super stability of yellow gunpowder, it cannot be detonated by flint alone, so Yan Bing followed the principle of modern rifle bullets and wrapped black gunpowder behind the yellow gunpowder with straw paper as a primer to activate the yellow gunpowder.
Then Yan Bing broke the traditional front-loading design of the Whitworth rifle, and instead opened a foldable steel clamshell on the barrel near the rear sight.
When it is time to load the gun, the soldier only needs to press the machine spring on the side of the gun body with the thumb of his left hand holding the gun, then grab the rear sight with his right hand and pull it up, and the back half of the hexagonal barrel will be flipped out.
, and the length of this barrel is just enough to stuff a wrapped firing powder pack and a hexagonal bullet, and then push the turned-up part back, push it forward, and snap it into the machine.
reed.
This design draws on the design prototype of the world's earliest rear-loading rifle, which will greatly reduce the reloading time of the flintlock gun.
Although the reloading speed is still slightly inferior to the compound crossbow, considering the range, power and accuracy, it has far surpassed the former in all aspects.
However, this experimental innovation will also mean that this modified rifle will face a greater risk of bombing and the test of barrel life.
Therefore, she must be present today.
Not only as a witness, but also as a supervisor, she did not want anyone to lose their life due to a moment of carelessness due to insufficient understanding of gunpowder.
While thinking about it, Yan Bing had already arrived at the shooting test site one mile east of Yingxian Academy. This was originally the place where she asked craftsmen to check whether the composite crossbow was qualified. It was also a weapons test site that she had specially prepared in advance.
It covers an area of six hectares, which is exactly the size of a regular stadium. However, instead of stands, there are piles of gravel bags surrounding the venue, and there are patrol teams patrolling the perimeter.
When Yan Bing entered the testing site, more than a dozen craftsmen had already fixed the gun on the wooden frame and tied the traction rope. They seemed to have been waiting for her anxiously for a long time, but they did not dare to complain and could only sigh in a low voice.
They all express the same meaning.
You're so lucky to be here...
Looking at their anxious expressions, Yan Bing smiled awkwardly, then skipped a series of speeches prepared in advance, walked directly up to them, raised a hand, and shouted loudly: "Test Rifle No. 1!!
put--!"
The craftsman, who had been waiting for a long time, laughed with his mouth open, pulled the traction rope, and pulled the trigger. With a bang, the bullet came out. In just a few tenths of a second, he saw the sand at the end of the wall.
A cloud of dust rose up on the stone bag...
The craftsman's laughing expression was stunned for a moment, then he laughed and jumped, shouting loudly: "I succeeded!!! Hahahaha!! I succeeded!!!"
Yan Bing chuckled.
Sure enough, there are not many normal people engaged in scientific research...
Ignoring him, he raised his hand again and shouted loudly: "Test Rifle No. 2!! Put--!!"
Looking at the craftsman again, he didn't know whether he was too nervous or because he was anxious about waiting. He tightened the rope and pulled hard. At the same time as the gunshot, the wooden frame fell to the ground. Everyone immediately fled in all directions, except for the one just now.
The idiot celebrating was still jumping up and down in place, completely unaware of what was happening...
After the dust settled, everyone walked out of the bunker one after another.
Manager Fang went up and gave the man a slap on the head, and cursed: "I'm not asking you to tug of war! Why are you using so much strength!! You idiot!!"
Then he picked up his robe, ran to Craftsman No. 1, and kicked his leg.
"You really don't want your life!? The gun fell down just now, and you're still jumping like this!!"
Fortunately, the No. 2 gun did not explode, but the bullet had already flown to nowhere...
Yan Bing tried to persuade Director Fang for a few words, then raised his hand and said: "Test No. 3!! Start!!"
The third craftsman then pulled the traction rope, and a gunshot rang out! The bullet came out! There was no explosion!
Yan Bing nodded. As expected, the pressure resistance of a steel barrel is not comparable to that of a wrought iron barrel...
For this test, they prepared a total of ten rifles.
The amount of gunpowder in each rifle is increased by baht taels in order to test the critical point of the barrel's pressure resistance.
In this way, the experiment continued until the seventh one, and the chamber exploded...
There is no need to try the remaining three, they will explode even if they are tried.
So Yan Bing ordered everyone to continue testing five of the remaining nine rifles according to the gunpowder quantity of the No. 6 gun, and four of them according to the gunpowder quantity of the No. 5 gun.
Because this step is to test the durability of the gun, so as to select the most suitable firing amount, and then conduct specific tests on range, power, and accuracy.
But...it will take a lot of time...
Yan Bing asked again about the sand mold cannon casting process.
Manager Fang pondered for a moment and then said slowly: "Now the sand mold has just been formed. It will take at least a month or two to fill the molten steel, then mold it and cool it, and then drill and polish it..."
This is basically what Yan Bing expected.
The sand mold casting method can be said to be the most efficient method before molding in mechanized factories, and there is no other method.
So much so that this method has been used even until modern times.
Of course, it is no longer used to cast cannons...
Instead, it is mainly used in the casting of mechanical parts.
There are two types of sand mold making methods.
One is the one-piece casting method. After the molten steel is completely cooled and formed, the sand mold of the gun barrel is then broken, and a complete artillery is obtained directly.
The other is the solid casting method. The cast gun body is solid and needs to be drilled and polished later. Although it is more time-consuming and laborious, its muzzle is drilled later, which will make the gun wall more solid.
Even and smooth.
Logically speaking, Yan Bing should choose the second option.
But that's the conventional round barrel option.
She produces hexagonal artillery!
The cannon wall itself is thicker than other artillery pieces. It can be polished and trimmed in the later process of polishing the hexagonal barrel. Naturally, the first method, which is more time-saving and labor-saving, was chosen, the one-piece molding method.
Yan Bing praised the skills of Director Fang and the dozen or so craftsmen, and highly affirmed their work during this period. After exchanging pleasantries, he put his hands behind his back and stumbled back.
I was walking contentedly on the streets of Tongshun City, dreaming about how to build a modern army, when I suddenly realized something was not right...
How come it's broad daylight... not a single restaurant on the street is open, they all have their doors hung up... they're closed??
