Chapter 250 A total of eight yin and yang rifling lines!Create rifled guns! .
【Ding dong! 】
[Congratulations to the host, using 50 shock points to successfully exchange for a set of diamond knives! 】
The mechanical sound of the system sounded in Ning Chen's mind again.
next second.
An exquisite wooden box suddenly appeared in front of Ning Chen!
Ning Chen stretched out his right hand with a smile, and gently opened the box in front of him.
Subsequently.
The titanium alloy dog eyes of a certain prince suddenly burst into light...!
"Fuck...!"
"The system is so sweet!"
In this wooden box.
There are more than ten handles of various knives, large and small!
The main body of the knife is made of titanium alloy, exuding a bright and chilling light!
And at the tip of the knife.
But it is the legendary diamond!
Under the sunlight, the tip of the knife looks so bright and dazzling...!
"As expected of the system!"
"It's awesome, 666!"
Ning Chen laughed out loud, the smile on his face was as bright as a flower.
Reaching out from the box, he took out a medium-sized short knife.
It shook under the sun for a while, then clicked twice, and turned its gaze to the cannon on the other side again!
"Rifling, rifling..."
"The so-called rifling is actually composed of two lines, Yin and Yang!"
"In other words."
"It's one convex and one concave, two phases interweaving spirals, and finally a rifled gun!"
talking room.
Ning Chen had already grasped the knife and stretched his arm into the cannon barrel!
The essence of rifled guns.
The reason is that there are convex and concave grooves or ridges inside, intertwined with each other, and distributed in the barrel in a spiral shape!
And to do this step.
Undoubtedly, it is extremely difficult!
The most primitive rifled cannon was made by burning the barrel red and then planing it by craftsmen.
But now.
These craftsmen of the Tang Dynasty could not master the manufacturing method of rifling in a short period of time.
and so.
Ning Chen can only wait for them to forge the gun barrel, and then start to plan it inch by inch with a knife!
In the garden courtyard of Bieye.
The current Lord Ningguo lay on the stone platform, holding the diamond knife in his hand, and began to plan the rifling slowly!
"throat……"
The clanging sound continued to resound with Ning Chen's hand movements.
Fortunately, what Ning Chen held in his hand was a diamond knife that cut iron like mud.otherwise.
It is simply impossible to carve grooves on the inner wall of the barrel!
Slowly move with the right hand holding the knife.
Ning Chen also drew out his left hand, covering the top of the gun barrel with his entire palm.
With the movement of the right hand, slowly exert force to the right, so that the gun barrel, which weighs more than a thousand catties, slowly rolls to the right!
Because the rifling is the reason for the helical shape.
Therefore, Ning Chen had to put up 12 points of energy, so that the two movements of the left hand and the right hand could be coordinated extremely closely!
otherwise.
Once there is any deviation.
This well-built artillery can basically be called a half-useless...!
It didn't take a while.
On Ning Chen's forehead, there was a dense layer of sweat!
Sweat slid down his cheeks, and finally dripped on Ning Chen's brocade clothes, leaving faint traces...
As the days gradually move, time is also quietly passing away.
Finally, at some point.
Lord Ning, who kept the same movement for an entire hour or two.
The somewhat stiff body suddenly moved slowly.
then.
The red right arm, which had been scorched by the high temperature inside the gun barrel, was slowly pulled out from the dark muzzle of the gun!
"call……!"
Ning Chen let out a long breath of foul air.
Then the body fell backwards, and fell heavily on the lawn behind!
Slightly closing his eyes, looking at the sky and white clouds, he felt exhausted for a while...!
"It's tiring!"
Ning Chen let out a long sigh.
Although there was tiredness that could not be concealed on the face, but in those eyes, it was full of
Full of excitement!
Rifled guns, done!
A total of eight yin and yang rifling lines were finally carved out by Ning Chen's hands!
Each rifling is tightly intertwined with several others.
It is in a spiral shape, extending from the muzzle position to the bottom of the barrel!
The angle is just right, without any slightest flaws, just like a perfect work of art!
And all of this.
They all came from the handwriting of Lord Ningguo of the Tang Empire!
It can be called uncanny workmanship...
"It took me several hours to complete the eight rifles!"
"But if we plan the rifling in the future, it won't take so long..."
Ning Chen grinned and smiled.
The whole person was lying on the green grass very relaxed, smelling the fragrance from all around, slowly shaking his head...
The rifled gun was finished.
Then, the only thing left is to build the Datang Navy!
"That's how it works."
"Before this month, we can complete our goal of going to the south of the Yangtze River and return to Chang'an!"
Thinking of his wife who is the current princess.
Ning Chen had a gentle smile on his face...!
Shortly after.
Ning Chen propped his elbows on the grass and stood up from the ground.
He raised his hand to straighten his robe, and then clapped his palms heavily!
Followed by.
The guards of the Duke's Mansion who have been waiting in the distance.
After hearing the call from his lord, he hurriedly ran from a distance.
"Move this thing to the trailer rack."
"Pull it outside the other industry, find an open place, and prepare for a shot!"
"Be careful, this thing is sinking!"
"Don't accidentally let go of your hand and smash you half to death..."
Chapter 251 Chengchen: Where is the Italian cannon of my country? !Fire me, fire me! .
Dirt road between fields.
Ning Chen was wearing a thin robe, walking slowly in the fields.
behind him.
A team of guards from the Duke's Mansion were pulling cannons mounted on wooden carts.
And carrying the wooden box containing the shells, slowly walking forward.
"Be careful when you carry the boxes, don't knock the things inside!"
"When the time comes, it will accidentally cause an explosion, and you will all be blown up half to death."
"My country has to spend money to heal your wounds..."
After hearing this, all the guards of the Duke's Mansion sighed inwardly.
When did my father-in-law become so... "a dog"...
Shortly after.
Everyone came to a hillside lined with trees.
Ning Chen raised his hand to cover the scorching sun, opened his eyes wide, and looked at the scene in front of him.
Then he laughed, waved his hands, and said to his subordinates:
"Okay, this is it!"
"Come, come, put the cannon on for me, the Duke of this country will fire the cannon himself!"
Hear the orders of his own country and lord.
All the guards of the Duke's Mansion quickly followed Ning Chen's instructions and set up the artillery mounts!
Then the cannon weighing more than a thousand catties was moved down, placed on the cannon mount, and secured!
After doing all this.
Everyone saw Grandpa Guo waved his hand again, and a few words popped out of his mouth...
"Okay, get out!"
