Seeing that Liu Chan was looking forward to it, Zhuge Liang nodded and said: "During the southern expedition, I once got a man named Pu Mingyuan. He has high attainments in this field."
"Pu Yuan?" Liu Chan was stunned for a moment. Although he was not very familiar with this person, but to be evaluated like this by Zhuge Liang, I believe he must be outstanding.
"Exactly!" Zhuge Liang affirmed: "If Your Majesty needs it, I will bring him to see Your Majesty tomorrow."
"Okay, okay, okay." Liu Chan was very happy.
Gunpowder has been developed, and if you want it to show its power on the battlefield, it is best to make guns and cannons.
If guns and cannons can be made, let alone one Cao Wei and one Soochow, even if there are ten more Cao Wei and ten Soochow, the Han can still blow them up until they lose their armor.
With such magical weapons, is it difficult to unify the world?
Zhuge Liang recommended Pu Yuan, and Liu Chan was naturally in a good mood. In order to let Zhuge Liang understand the power of the bomb more clearly and intuitively.
Liu Chan made another bomb.
Only this time, he didn't add nails to it, just black powder.
The bamboo tubes are still the same size, and the proportions of gunpowder are similar.
The bomb was detonated again next to the bamboo tube previously buried.
This time Liu Chan did not ask Zhuge Liang to retreat to the room. Instead, after lighting it, the two quickly retreated to a place fifty or sixty steps away.
Bang——
There was another loud noise.
This time, both Liu Chan and Zhuge Liang saw it very clearly. At the moment of the explosion, the flat ground was instantly shaken and earth flew everywhere, leaving a pit of about one meter.
Zhuge Liang was naturally surprised because it was his first time to see an explosion with his own eyes.
But Liu Chan was ordinary. Except for the sound of the explosion, which gave him an instinctive pause, he had no other feelings. If we talk about the picture, it should be similar to the power of a grenade in movies and TV series.
But this is already perfect, after all, this is the Three Kingdoms of more than 200 AD.
After the two test explosions, Liu Chan told Zhuge Liang the principle of black powder explosion and what would happen if it was used on the battlefield.
Through Liu Chan's explanation, Zhuge Liang also had a certain understanding of black powder and bombs.
Of course, he also looks forward to using it in future wars.
......
The next morning.
Zhuge Liang once again entered the palace to meet Liu Chan.
Only this time, he didn't come alone.
"Pu Yuan, a humble minister, pays homage to His Majesty."
"Long live my emperor, long live, long live."
In the Xuanshi Hall, Pu Yuan gave a big salute to Liu Chan. Liu Chan raised his eyes and glanced at him. He was about forty years old, with dark skin and not very tall. He was about 1.65 meters tall, but he was very strong. "Pu Aiqing!" Liu Chan asked: "Do you know the art of smelting and forging?"
Zhuge Liang had recommended this person yesterday. Later, Zhuge Liang also said that the swords forged by Pu Yuan were extremely sharp and much harder than ordinary swords. The reason why his swords are sharp lies in his unique smelting skills.
"Back to Your Majesty!" Pu Yuandao said, "I know a little bit about it."
Oh, quite modest. Liu Chan was very satisfied. Then he spread out a drawing he drew last night and asked Pu Yuan: "Can Aiqing cast this thing?"
Pu Yuan walked closer and looked at the drawing. The objects on the drawing looked very simple.
It is a large cylinder, thick at one end and thin at the other, and hollow in the middle.
"Your Majesty!" Pu Yuan asked: "What is the use of this thing?"
The objects in the picture look very simple. The only difficult thing is probably the hollow in the middle. However, Pu Yuan thought about it and realized that with his many years of forging experience, it is possible to forge a hollow tube.<
/p>
But, what is this thing used for?
He has to know the use before he can figure out how to forge it.
Liu Chan said: "This thing is called a gun barrel, and it is used for firing."
Pu Yuan was stunned: "Cannon barrel? Fire?"
Looking at Pu Yuan's reaction, Liu Chan was not surprised. After all, artillery would not be available for hundreds of years. He didn't understand, and it was not surprising.
Liu Chan nodded and said: "Yes, it is used to launch cannonballs."
Pu Yuan was still confused by what he said just by mouth. Liu Chan had already prepared for this, and he immediately took out a small model.
This thing was something he had seen in his previous life when he was watching short videos made by some great people.
The middle of the piece of wood, which is as thick as a thumb, has been hollowed out.
"My dear, please take a look, this barrel looks like this;" Liu Chan said as he put a little bit of black gunpowder into it, then punched it with a small wooden stick, and finally put in an iron bead the size of a mung bean.<
/p>
"Watch it!" When everything was ready, Liu Chan reminded Pu Yuan: "The process of firing the barrel is like this."
Zhuge Liang, who had been silent until now, became interested at this time.
I just saw an explosion yesterday, but I really don’t know what it will look like when launched, and how to launch it.
After all, Liu Chan also said yesterday that as long as the launcher is good enough, the range of this thing can reach several thousand meters.
As the two watched, Liu Chan inserted a very thin fuse into the small round hole at the end of the barrel, and then lit the fuse.
Zizi——
When the fuse is ignited, small dazzling sparks immediately emit, and the sparks continue to spread downward, and finally disappear into the round hole.
At the moment when the spark entered the round hole, a crisp "bang" sound was heard, the barrel shook, and the iron beads inside immediately ejected, and finally hit a large cylinder a few meters away, leaving behind
A small pit.
Zhuge Liang and Pu Yuan were both stunned.
Is there such an operation?
"Do you see it clearly?" Liu Chan asked Pu Yuan: "This is the artillery I am talking about. This is just a small model. What I want is a larger barrel, a barrel made of steel."
But after Liu Chan finished speaking, he looked at both of them with confused faces, especially Prime Minister Zhuge Liang. He really didn't understand the principle.
Although Pu Yuan was at a loss, he probably already knew the working process of this thing, which is that it must be hollow inside because something needs to be put inside.
This chapter is not over yet, please click on the next page to continue reading!
As for why the sound was made and why the iron bead was shot out, he still couldn't figure it out for a while.
"The texture of this gun barrel needs to be thick and solid;" Liu Chan said while taking out a small wooden tube with a very thin wall.
Liu Chan said: "Look, my dear, if the wall of this pipe is not thick enough and the material is not strong enough, it will look like this..."
"Stand a little further away." Liu Chan reminded.
Then it's the same process, loading gunpowder, placing iron beads, and finally lighting the fuse.
After some operations, Liu Chan instinctively stepped back.
Bang——
There was another crisp sound.
However, only then did the iron beads stop shooting out.
The barrel was blown to pieces.
Fortunately, Liu Chan reminded them to take a few steps back in time, otherwise the fragments could have hurt people.
"You see..." Liu Chan pointed to the fragments on the table and said, "If the wall of the pipe is not strong enough, this is the consequence - it will explode."
Liu Chan has also thought about making guns, but with the current technology of this era, it is still difficult to meet the requirements.
There is also the manufacturing process of firearms, which is relatively complicated.
Neither can Liu Chan.
Alas——
But artillery is relatively easy.
For example, the manufacturing technology of the red cannon of the Ming Dynasty is not very complicated. Various short video experts in later generations can easily make mini versions of the red cannon.
The model Liu Chan demonstrated just now is actually a mini version of the red cannon he had seen in his previous life. These two models were made to allow Pu Yuan to see more clearly and to know the working principle of this cannon, which would also help him in the future.
Cast gun barrel.
Both types of gun barrels had been demonstrated, and Liu Chan asked Pu Yuan with some anticipation: "Does Ai Qing understand... that it's possible to cast this thing?"
