Secondly, there's the firing pin at the back of the pistol bullet, which is used to strike the bullet.

These principles are relatively simple. As long as the parts are made according to the revolver parts designed by Zhu Yunwen, there will be no problem.

Zhu Yunwen then gently pulled the trigger, and the firing pin at the rear of the pistol struck the bottom of the bullet at the rear of the chamber violently.

As we mentioned earlier, mercuric fulminate is very prone to explosion when subjected to friction or impact.

Under the violent impact of the firing pin, mercuric fulminate almost certainly exploded. So at that moment, a loud bang suddenly rang out, which made Zhu Yunwen's face show an excited expression.

Of course, such a loud noise was not simply produced by mercuric fulminate.

After all, mercuric fulminate is located at the bottom of the bullet, and only in small quantities, so its combustion won't be very loud.

The real sound comes from the large amount of gunpowder filling the middle of the bullet.

However, the reason these gunpowder pieces exploded was naturally because the mercury fulminate was detonated by the impact of the firing pin, which then ignited the gunpowder.

This demonstrates that Zhu Yunwen's mercuric fulminate bottom fire was successfully produced.

Moreover, both the bullets and the pistol were successful.

Just as he was thinking this, Zhang Shan, who was standing beside him, turned pale and looked at Zhu Yunwen, saying:

"Your Highness, why does this thing you made make the same sound as a musket? And what about that door..."

He pointed to a door across the street, and Zhu Yunwen quickly stepped forward to take a closer look.

There was a hole in the door.

It should be noted that the door to the East Palace is a full five centimeters thick.

It was only about the length of a little finger, yet such a thick door was pierced by a single bullet.

That alone is enough to demonstrate the power of these bullets and pistols.

So Zhu Yunwen smiled and said to Zhang Shan:

"That's right. What I made is a weapon similar to a musket, but it's more convenient and more powerful."

Zhang Shan stared in disbelief and said:

"This is not just more powerful, it's huge! If it were a musket, it would probably only be able to be embedded in this door."

But what you made actually pierced through such a thick door. That's terrifying!

Zhu Yunwen smiled, then took a deep breath and said:

"When a bullet is fired from such a closed space as the cartridge case, and it passes through the rifling, the texture of the bullet itself and the rifling inside the barrel cause the bullet to spin, making it faster and more stable."

Therefore, it's not surprising that it can unleash such power. With this in hand, tell me, if I were to truly face that so-called expert from the Eastern Island, do I have any chance of victory?

Minister of Revenue Zhang Shan hurriedly spoke:

"It's not just a chance of winning, it's practically a sure thing! Your Highness the Crown Prince is truly mighty."
