"This is... a cannon!"

Li Yang almost cried out in surprise, his eyes popped out.

I saw that what was placed in front of me was indeed a cannon, a bronze cannon!There is a cannon body, a barrel, and there are four bronze wheels under this cannon, which can be pushed and moved, which is simply awesome.

At this moment, Li Yang was really stunned. This guy... actually made the cannon 2000 years in advance?

Li Yang couldn't believe his eyes.

"Dean, this is the new invention that the officer mentioned, the shotgun."

When Gongshu Chu saw Li Yang's surprised expression, he was overjoyed and a little bit proud and proud.

After all, to be able to shock Li Yang, a genius who invented papermaking and printing, made Gongshu Chu feel a sense of accomplishment in his heart.Because for him, this is a kind of success, a kind of recognition.

He Zhang on the side was also very curious, touched the cannon, and asked: "Gong Shu Chuan, tell me quickly, what is this for?"

Gong Shuji, who was full of confidence, said with a smile: "This shotgun is a weapon for attacking the enemy from a long distance. It can be regarded as a small trebuchet."

"Stone lifter?" He Zhang was confused when he heard this, and looked around the cannon in a daze, but he couldn't see where to throw stones, so he couldn't help but wondered: "This... how to throw stones?" ?”

Without waiting for Gongshu Chu's answer, Li Yang began to guess: "Gongshu Chu, you are a shotgun, but you fill the bottom with gunpowder, and then fill it with gravel, bronze, and iron beads, and use the explosive power of the gunpowder to shoot the small iron Shoot the beads out to kill the enemy?"

"Dean, how do you know?"

This time, Gongshu Chu was really shocked.

Because the weapon I built was indeed as Li Yang said, using gunpowder to shoot iron beads out to kill the enemy.

It's just...how did Mr. Zhen know?

Just because he took one look and understood everything?

Thinking of this, Gongshu Chu was once again overwhelmed by Li Yang's wisdom.

Zhen Guojun is really extremely smart, no one can compare to him!

"So, my guess is right?" Li Yang smiled, and he was more sure in his heart, this is the cannon!And it's an authentic cannon!

To be honest, Li Yang really admired this public record this time.

The things I invented are not so much inventions as copying, using things that already existed in later generations to guide the people of the Qin Dynasty to create.

But the Gongshu Book in front of him is different. He really invented a cannon entirely by his own talent.This is not something ordinary people can do.

Talent, what a talent!

While Li Yang was amazed, Gongshuji also praised with admiration: "The dean is so intelligent, he can know the principle of this shotgun at a glance. It's really amazing."

He Zhang also said very well: "What Gongshuji said is very true. I didn't know its principle just now, but the dean knew it at a glance. This shows that the dean's wisdom is beyond my reach!"

Everyone nodded.

Li Yang smiled wryly: "You don't need to flatter me, Gongshu Chu, tell me how you invented it!"

Yes, what Li Yang wants to know most at this time is Gongshuchu, how did he invent this cannon, after all, this is a full 2000 years ahead of the cannon.

Seeing Li Yang's interest in the shotgun he invented, Gong Shuchu was also very happy, and hurriedly replied, "Xiaguan invented it based on the principle of fireworks."

"Oh, so that's the case." Li Yang suddenly realized.

"The lower officials saw that the fireworks could fly several feet into the sky, so they thought, if the amount of gunpowder is increased and the fired fireworks are replaced with stones, wouldn't it be possible to become a trebuchet? So, The next official tried it out. The result... Alas!"

Speaking of this, Gongshu Chuan sighed, and continued: "The stone is too heavy, and it is difficult for gunpowder to shoot the boulder a sufficient distance like fireworks. Later, the lower officials changed the heavy stone into pebbles and iron beads. It succeeded. Especially the uniform iron ball, with enough gunpowder, its range can even reach [-] paces."

Three hundred steps is actually not as good as the effective range of the light Qin crossbow.

"Although the effective range is not as good as the Qin Nu, its lethality is several times more terrifying than the Qin Nu!" Gong Shuchu looked proud.

Li Yang nodded, he could imagine that this kind of artillery is actually an enlarged version of the original firecracker.

Because the original gunpowder used gunpowder to shoot out the shotgun.

One shot down, a bunch of small steel balls will beat you into a sieve shape, full of blood holes, it is really scary.

He Zhang on the side couldn't wait any longer, and hurriedly said, "How about trying to shoot once?"

"He Shangshu wait a moment, the next official will perform."

Gongshu Chu immediately agreed, and then began to fetch gunpowder and load it into the cannon.

After loading the gunpowder, the next step is to load the iron beads.

His iron beads are all processed, and each grain is the size of a soybean, which is very uniform.

In this cannon, he loaded iron beads, at least a hundred.

As soon as the gunpowder and shotgun were loaded, someone below had already placed a wooden bed board two hundred paces away.

Everything was ready, at this time Gong Shuji turned his head and said to the crowd: "Stand back a little bit, everyone, it is very deafening."

Naturally, Li Yang stepped back two or three meters knowingly, because he was worried that if the gun barrel exploded, wouldn't it hurt him?

"Your Majesty, this is about to start a fire!"

Gongshu Chu pointed the gun barrel at the wooden board in front, said something, then took out a fire pocket, and pointed at the lead wire connected to the small hole at the bottom of the gun barrel...

With a sound of "Here~", the fuse was ignited at once, and then rushed into the barrel.

then……

"Oh!"

A shock resounded through the sky.

I saw a puff of thick smoke with flames shooting out directly from the gun barrel...

"boom!"

At this very moment, the piece of wood two hundred steps away in front suddenly heard a muffled sound, and the whole board fell to the ground as if it had been hit by something.

Everyone was shocked by the huge gunfire, and it was not until after a few gasps that they hurried towards the position of the wooden board.

A look, good guy, I saw that the whole board is full of dense holes.

What's more, this wooden board is half a centimeter thick. At this time, there are hardly many iron beads embedded in it. The iron beads have all been penetrated, so the whole wooden board looks like a sieve!

Seeing this effect, everyone couldn't help being stunned.
