The two of them studied it for a long time but couldn't figure it out. Finally, they concluded that this thing couldn't be fast.

It was also at this time that the opportunity came.

Liu Derou also encountered trouble. It was not difficult to make black gunpowder into particles, but the difficulty was how to make the particles consistent in size.

My brother tried many methods, but the results were not satisfactory.

As a result, Liu Derou is so anxious that she can’t do it, so I won’t do it anymore!

Isn’t Ning Wang just trying to prevent gunpowder from getting damp? I sealed the gunpowder from leaving the factory and stuffed it into the barrel of the gun directly with the packaging.

So, Liu Derou also began to take a small cannon and started studying it, mainly studying the amount of encapsulated gunpowder and the caliber of the barrel.

However, after Yi Simayin and Sun Gong found out, they immediately stopped doing it.

"We can't even get it clean from the cannon chamber. Do you have to stuff the packaging in? Will you let people live?"

Of course, Liu Derou was not used to it, "My task is to package moisture-proof. I care whether you can take it out! Otherwise, what should I do? Let's make an iron packaging and let your residual medicine be taken out together?"

“…”

“…”

Yi Simayin and Sun Gong were petrochemical on the spot.

Liu Derou's unintentional anger was to help them solve the problem from another perspective.

Yes, wouldn’t it be enough if I don’t let the residual medicine and coke enter the gun chamber?

Get an iron jar and put the gunpowder in it and put it into the barrel together. After the fight, just take out the jar?

Liu Derou was also stunned and said something even more magical, "If you put the shells into the can, the gunpowder will not need to contact the outside world from the ground to the launch. Not to mention getting wet, it will not delay the shooting of the cannon!"

They did it as soon as possible, and the three of them pulled a few Damascus blacksmiths into the group.

So, the first shell of the Song Dynasty was born.

“…”

After hearing everyone's "heart journey", Zhao Wei was completely confused.

This is OK!?

He never dared to think about high-end products such as one-piece shells.

Because it is impossible, the breech gun has not even been visible yet. What shells do you want?

However, this thing was really placed in front of Zhao Wei, and he had no choice but to believe it.

Although it is very simple, it is indeed a shell.

The bullet is still a spherical iron ball. It sits on an iron tube with an inner diameter of the gun barrel, and looks like a large pistol bullet.

Because the attacking medicine has not been invented, there is no bottom fire. The tail is a round hole the size of a copper coin is sealed with wax.

When firing, just pierce the wax seal and use a fuse to ignite the outside.

Yi Sima was proudly showing off, "Your Highness, what do you think? In addition to solving the problem of dampness of gunpowder, it also has the problem of cleaning the bubble. It has another advantage, that is stability."

"The amount of medicine filled in each shell is certain, and there will be no deviation due to the more or less guns, and the attack will be more accurate."

"And, there is one of the biggest advantages of this thing, that is..."

"Quick!" Zhao Wei rushed to the front, "The biggest advantage of an integrated shell is fast."

A lot of steps are eliminated, and the rate of fire is not comparable to that of the original bore gun.

Judging from the firing rate of the small cannon, the time for one shell can be fired, this thing can fire at least three rounds.
