(This is the first week of the author's job-hopping, unfamiliar with the project, and the current author Jun is also the company's copywriting director, so there are more things to know, usually in addition to work, I have to watch some things to charge, but I will continue to update the code word when I have time, because writing books is my hobby, and I will never give up.) Please bear with me if the update is slow! ）

----------------------------

The barrel of the Ryujin's Wrath is very long, and the wall of the pipe is very thick, and the overall appearance is a shape that gradually thickens from the muzzle to the tail of the gun, which is very consistent with the principle of high to low bore pressure when gunpowder is burned.

At the center of gravity of the gun body, there are cylindrical lugs on both sides, and there are crosshairs and illumination gates, so that people can calculate the trajectory according to the parabola, and the gun can adjust the angle of fire with this axis, and change the firing range according to the amount of gunpowder, with high accuracy.

When Manjiro is reloaded, he only needs to ignite the propellant in the barrel through the fire rope to make the dragon god roar, which is a front-loading gun that has crossed the ages and should not have appeared in the Qin Dynasty.

"At first, I thought it was a solid bullet, but I didn't expect it to be hollow." Taka Kato sighed as he picked up a cannonball.

"It's really surprising, if it weren't for the lack of evidence, I would have thought that someone traveled back in time to make it, but every archaeological discovery is rewriting history, isn't it?" I didn't go to help Manjiro, but let Takashi Kato stand behind me, and I faced Momoto directly.

In the face of a murderer who has lived for so long, I have reason to believe that he is still smiling and talking to us one second, and the next second he will immediately change his face and attack us.

Seeing that I was watching him with vigilance, Baihu Shi behaved quite calmly, and he sat down directly on the spot with a smile on his face.

The clothes on his body are much more torn than before, and he must have had a fierce fight with Yaksha when he came here, and the consumption was not small, so he had to use us to get out of trouble.

Otherwise, he would still be hiding in the shadows and attacking us.

Now that I'm wearing armor, I don't have to worry too much about being skinned by him, but just in case, I'll keep an eye on him until Manjiro lights the cannon and gets us out of danger, and then I'll take care of him.

The shell is hollow, which means that it will be very powerful.

During the Jiajing period, there was a kind of artillery called "poisonous fire flying", the barrel was made of wrought iron, loaded with gunpowder more than 10 taels and ignited and launched, the shells were cast by pig iron, and the bullets were filled with a number of "arsenic and sulfur poison", and the range after ignition could reach 200 steps (about 330 meters) away, and then it was broken and injured by violence.

This is the earliest record of the use of artillery to launch explosive bombs in ancient China, of course, in this magical mirage ship, everything can not be handled by common sense, even if there is really a dragon running out of the back, I will not be too surprised.

From this point of view, these three shells should be hollow metal balls made by the Gongyi family, and like the "poisonous flying fire" of the Ming Dynasty, the shells are filled with fine-grained black powder.

The principle of ancient artillery and modern artillery is basically the same, it is necessary to push out the warhead by the gunpowder explosion in the back, and then the warhead hits the ground and explodes.

The difference between the two lies in the problem of the production process of ancient cannons, compared with modern artillery, there is a gap in accuracy, and ancient cannons use earth gunpowder, low explosive power, and low pressure that the gun chamber can withstand.

Their warheads are also triggered differently: today's artillery is generally triggered by the warhead landing on the ground, and some even use altimeters or lasers to trigger them.

Ancient cannons were generally triggered by the fuse on the warhead of the cannonball, that is, there was another fuse on the warhead.

At the moment of firing the gun, the gunpowder in the chamber ignites the fuse on the warhead, which detonates the warhead after some time.

So, if you think that firing an ancient cannon is to pour gunpowder, load a cannonball, take a stick and poke it, and finally ignite the lead that sticks out of the barrel, and it will be over with a bang, you are very wrong!

While I was monitoring Hyakunoshi's movements, I watched Manjiro make the final preparations before the launch.

Manjiro took out a small wooden fuse from the shell box and loaded it into the front end of the shell (stuffed into the shell fuse hole).

Manjiro then checked the butt on the back of the shell, which prevented the unstable rolling of the shell during the ejection process.

This is because if there is no stock, the friction of the shell against the inner wall of the barrel will cause the shell to roll.

If the fuse is facing the burning high-pressure gas at this time, it will cause the fuse to be pressed into the bomb body and explode directly, then we will have a lot of fun.

If the butt is fine, the high-temperature gas will naturally leak from the gap between the shell and the barrel to the front of the shell and ignite the fuse during the discharge process.

In this way, the shell is ignited during the discharge, and after the shell flies out of the muzzle, it explodes at the time specified by the fuse.

So the question is, we haven't played this Wrath of the Dragon God, how long does it take for its shells to explode from launch?

It's been a long time, it's useless; It's too fast, and we can't get far before we explode in the air.

"Manjiro Ojisan, how long do you think the shells will explode?" I asked.

"I don't know about this, although it is brand new, it is too old, and according to the characteristics of the ancient cannons recorded by our family, the fuse burning time of these cannonballs should not all be the same, so I can only fire one first and give it a try." Manjiro said.

He has finished loading and is adjusting the launch angle.

"Well, I'm here to help take a look, but I can only try to hit the cannonballs in front of us in piles and on the corpses of monsters blocking our way." Takashi Kato said.

"Well, yes, otherwise we won't be able to run even if we get out. Ouyang is in charge, although I don't know the fuse burning time of the cannonball, but I can still control the fuse burning time I made myself, after you light it, you have 10 seconds to let everyone at the door quickly retreat here. Manjiro said.

In order not to distract the person at the door, we didn't use a communicator in our previous conversations here, except for the occasional sentence or two that we had to let them know.

"Okay, everyone at the door, after hearing my greeting, must all come back within 8 seconds, the cannon will fire on time, and all of them will follow my movements when the time comes, remember, they must be consistent with my movements." I said emphatically at a louder voice.

It's not that I'm wrong when I say 10 seconds is 8 seconds, it's that I want to leave two seconds for them to lie down.

On the battlefield, if a shell explodes nearby, people will lie down close to the ground, but in fact, this is completely wrong, and this will only die faster!

I once heard Ang Lee (see Volume 1) say that during the Vietnam War, American soldiers often found a strange corpse, with no wounds or blood visible on the surface, but the person had already lost his breath.

They tried to escape by relying on this method because of the shock wave released by the shell, which shattered all the internal organs in their bodies, and they hung up before they could react.

"Ouyang is in charge, I'm ready to light the fire." Manjiro is all set.

"Everyone, 8 seconds, fast !!" I shouted.

Wrath of the Dragon, don't let me down, it's up to you whether you can escape or not!
