A small steel cannon with a bracket and a turntable of firing angles, the main material is the 50 mm caliber steel pipe, and the firing part has been thickened and weighted to increase the strength and prevent the bore from exploding. The bracket adopts a four-legged propping bracket, which is short in front and long in the rear, and the geared angle turntable can adjust the angle of the muzzle.

As for the firing method, it is relatively primitive, filling the magic cotton from the muzzle, setting up a small hole in the firing part, inserting the fuse, compacting it with a strip, and finally putting in a steel ball as a shell.

This is the best cannon that Qin Song can design with the tools at hand. The steam engine and the small steel cannon almost exhausted all the materials Qin Song had at hand. The purpose of showing Leah is to test the power and communicate the supply of materials.

"What is this?" Luna leaned over curiously, her eyes wide at the muzzle, "A tube, what knowledge will there be in the tube?"

"Liya, do you remember the clay pot that day?" Qin Song asked with a smile.

Leah took a deep breath: "Impressed!"

"What if it's a tool. Can you fire a clay pot at the target location like a bow and arrow?"

"Like archery?" Lia was a little shocked, she had thought after she went back, the power of that clay pot was indeed amazing, but the shortcomings were also obvious, it was a fixed-point attack, very limited, and very dangerous to operate.

But now, listening to Qin Song's meaning, he can actually launch it.

"Yes!" Qin Song nodded, and picked up a cylindrical object about 5 centimeters long and more than ten centimeters long from the table next to him, which seemed to be wrapped in papyrus on the outside.

Considering the limited caliber of the small steel cannon, there is no way to make a real bomb for the time being. Relying only on demonized cotton to launch steel balls or stone balls, the striking surface is too small, and there is no rifling, and the accuracy is not high.

In addition to the conventional firing of steel ball shells, Qin Song diverged his thinking and thought of a way, which came from the ancient wisdom of the Chinese people - two kicks!

The principle of the second kicking is simple, the double-layer charge, and the bottom layer explosion produces a recoil force, so that the explosive part rises into the air and explodes in the air. The process is very similar to firing mortar shells.

The most important thing is that it is simple to make, with multiple layers of papyrus bonded with gum as the cannon body, sealed with earth and mortar. In order to increase the power, the blast part is refilled with steel balls, steel needles, and iron sheets, and the volley explodes, causing maximum surface damage.

The firing process will also be greatly simplified, lighting the fuse and putting in the barrel. Of course, the disadvantages are also obvious, there is too much debris left after the launch, which requires a lot of effort to clean up.

However, this was already a way for Qin Song to think of to maximize the power of the small steel cannon.

Of course, the second kick is only an attempt in the transitional period, as long as there is enough time, more powerful, real shells will be made sooner or later.

The steel ball bullet is used as a point kill, and the second kick is used as a surface kill, which can be used according to the actual situation.

There is no way, the caliber of the small steel cannon is really limited. If the caliber is large enough, even stones can bounce forward with the impact, causing a strong line of damage, which will be a miracle against cavalry charging in groups.

In short, extraordinary times, with extraordinary means.

......

"Ralph, it's up to you to light the fire!"

It's still the same as last experiment, and the ignition is still Ralph. He experienced a blast in his ear and was deaf for a full afternoon before his hearing recovered.

With two kicks in his hand, Ralph was about to cry.

Why me again?

Seeing that the others were running away again, many teammates looked at them sympathetically-the job of the master chief is really arduous.

The steel artillery mount is good, and the angle is adjusted to about forty-five degrees, which is convenient for estimating the firing range and explosion point. Qin Song adjusted everything and patted Ralph on the shoulder: "This arduous task falls on your shoulder." Remember, after igniting it, be sure to throw it in this canister and cover your ears to run as far and as far as you can. ”

With the last fright, Ralph became even more nervous, his eyes flashing with tears, and his lips trembling, "Okay, okay, Commander." ”

With Qin Song in the distance, his hand waved down slightly, Ralph swallowed his saliva, lit the fuse with a trembling hand, quickly stuffed it into the barrel, and ran with his ears covered.

Boom！

There was a muffled sound, and the powerful recoil made the entire steel cannon tremble, and the second kick shot out.

"Hoo ......"

There was a brief silence that put an end to Luna's explosion, and as soon as she put her hand down, there was another earth-shattering bang that exploded in the air.

Caught off guard, Luna shuddered, and if Leah had held her up in time, she would have almost repeated her ass squat.

"Two ...... Two sounds?"

Qin Song stared intently at the direction of the explosion, estimating the height of the explosion, which exploded at an altitude of about ten meters because of the parabola.

The distance between the explosion point and the launch point is about 200 paces, which is related to the length of the fuse of the secondary explosion. If the firing angle continues to be lowered, and the explosion point is a few meters away, the lethality should be further increased.

Of course, the specific effect still needs to be investigated on the spot.

The effect of the survey was similar to what Qin Song expected, because the explosion height was too high, the impact of the steel balls and steel needles was somewhat weakened, but they could still shoot into the soil about a finger deep.

Liya looked at the steel ball that Qin Song dug out of the soil, and said dumbfounded: "Your Excellency, how did you do it? Why did there be two explosions and fly out? and what happened to such a steel ball?"

She clearly did not understand the principle of the explosion.

"Leah, this is a complex design. To put it simply, the first pop creates momentum, like loosening a bowstring and shooting an arrow. The second explosion in the air was like pulling the second bowstring, sending countless steel balls out like rain. ”

"Oh my God, the balls are all embedded in the dirt. Luna gasped, "It's raining, and it's terrible if people are standing down there—oh my God." ”

Everyone was admiring, but Qin Song frowned, shook his head and said, "The effect is a bit bad." ”

This still doesn't work well??

"Qin, is this what you call the art of explosion?" Alice participated in the production of the second kick, and knew how many steel balls and steel needles he put into it: "Is it actually countless steel balls that cause damage?"

"Yes, Alice. Qin Song twisted the steel ball in his hand and nodded: "The internal pressure generated by the explosion will scatter the steel ball, causing a large area of damage. It doesn't look lethal, but - it can significantly weaken combat effectiveness. ”

"It looks like we need to improve it any further. ”

......

At the Ever Sentry, near dusk, Elena, who had recuperated her spirits, stood on the watchtower in the company of Linda, observing the movements around her.

"Linda, what do you think is in that clay pot?"

Elena was deeply impressed by the power of the clay pot, she had been thinking about this question, there could not really be any devil sealed inside, right?

Linda shook her head in silence, "I don't know. ”

"Bang, my ears are almost deaf. Now think about it...... Wait, Linda, there's a situation. ”

In the distance, in the misty night-shrouded wasteland, with bushes and boulders scattered together, Elena's keen dark vision found something different.

Behind at least two bushes, there was a faint shadow moving slowly.

"Are the orcs coming?"

"Shh......h

Elena held her breath and watched intently, and soon saw the bushes sway, revealing a beastly face spitting strange patterns through the cracks.

Elena's heart tightened: "It's an orc." ”

Linda put her arm on the shoulder, "Don't be nervous, Elena. See how many there are?"

"Hmm!"

Elena nodded, and began to search the rest of the figures. As the twilight gradually thickened, in the vision of ordinary people, the wasteland seemed to be an impenetrable dark fog.

And the orcs obviously didn't know that there was a pair of eyes that could pierce through the darkness in the distance, staring at them, and their actions gradually became bolder.

"One, two, three...... Four. Only four are seen at the moment. What should I do? Linda?"
