The opening of the barrel is not large, and the rifled cutter sticks into the barrel to push and pull, and the shadow makes it difficult to see the rifling.

The cutter resets, exits the barrel muzzle, the ratchet turns again, and the barrel rotates again by a fifth.

There are a total of five rifling wires for this cutting, and now the third rifling is cut.

"The output of the steam engine is stable!"

"Two rifling appeared in the barrel!"

"Third cut!"

As the mutters of the workers fell, the tiny cutting knives reached into the tube again, rotated, unloaded, and the third rifling was completed.

Zilazila.

The whole process was a bit slow, accompanied by a loud hissing that was the sound of knives cutting through the inner wall of the barrel.

"Downvote it a little more." Alan's voice rang in his ears.

The worker who looked at him came back to his senses, "Oooh. Then he quickly turned down the output of the steam engine.

Then again, from Allen's point of view, there is no way to see the cutter operating inside the barrel, so what is the basis for Allen's fine-tuning on the fourth cut?

If you knew the principle, they would not be ordinary workers, and the workers looked at each other and continued to wait for the machine to cut the fifth rifling.

After a long time, the five rifling wires of the first barrel were cut, and the orcs turned off the steam engine and machine tool, removed the barrel, and then looked at the barrel with their eyes to see the inside of the barrel up close.

The lines of the five spirals from near to far, as if opening and closing and contracting, converge at the end into an infinitely close point, full of wonderful artistic design beauty.

"Lord Allen, the five rifling wires are very clear, this is a successful product!" The craftsman shouted in surprise, making no secret of his admiration for Allen.

"No, it didn't work out, the third rifling showed a slight jitter as it cut to the depths, and three quarters of the way one node was crooked, and the back line was also crooked." Alan took the barrel and looked at it with his eyes.

If you want dynamic data, you need to use the identification technique every second to obtain the dynamic data that occurs every second when the machine is working.

"Ah......h

"I'll see."

Abel was curious, took the barrel outside, stretched out his eyes to block the muzzle of the barrel, and saw the bright inner chamber of the barrel with the help of the brightness of the sun, and the five rifling wires rotated in a spiral form, and after looking carefully for more than ten seconds, Abel felt that the lines were rotating.

"It seems that a line is crooked." The great blacksmith Abel shook his head, a little dizzy.

The principle of the rifling machine is simple, but the steam engine is not a stable output tool, and Allen needs to be fine-tuned.

Half an hour later, Allen and the others wasted a lot of barrels to complete the adjustment, and then the rifling cut with the steam engine was very stable and the arc was moderate.

In addition, Mini bullets that fit into the rifled barrel are also in hot production.

With the rifling machine for flintlock barrels, the next industrial machine tool is the barrel rifling machine for cannons.

It also takes a while to make that thing, and you have to wait for the next batch of steam engines to be made, not that the machine tool can be used after it is built.

Tomorrow in the face of the tide of beasts, it is still dominated by smoothbore flintlock guns, rifled guns have not yet entered the mass production stage, and the caliber of the newly made rifled guns is slightly smaller than the caliber of smoothbore guns, with a caliber of about 12 mm.

Due to the change in caliber, the firing device and the butt had to be redone, which was a time-consuming and laborious task.

……

It was not yet dawn, and the night was thick.

The cat-eared orcs patrolling the city walls found that countless birds in the forest had flown over, densely packed and obscuring the bright starlight.

The cat-eared orc gripped the flintlock pistol in his hand, a little nervous.

The restlessness of the birds is no accident, and the news of the imminent arrival of the beast tide in the city has long been spread among the musketeers.

"Goo!"

The strange voice of the pigeon sounded overhead, and although the cat-eared orc could not understand the pigeon's language, the two branches in the pigeon's mouth fell beside him, and he immediately knew what was happening in front of him.

According to the wartime pigeon body language table, two wooden sticks are thrown at the wall, and two cooing sounds, indicating that the animal tide is coming.

The form was made by Lord Allen himself, and the previous week's military training had also included a pigeon body language exercise, and all the musketeers were accustomed to the convenience of knowing the war situation with the eyes of animals.

"The beast tide is coming!"

The wall-head soldiers immediately ran to the giant bonfire tray of the city wall, burned the kerosene burning stick at the head of the wall into the plate, and threw all kinds of firewood from the wall into the bonfire tray by the way.

Another messenger picked up a huge banana fan next to the campfire and fanned the flames with all his might.

Whirring, the fire burned violently.

Black smoke billowed up, reaching the starry night, and the firelight reflected the beacon tower.

The soldiers of the beacon tower next door saw the beacon fire and lit it with it, and the smoke billowed out.

In less than a few minutes, beacon flames were lit along the entire wall of Tomorrow City.

The night patrolmen in the city took to the streets to beat gongs and drums, and their voices were very loud, hoping that the whole city would wake up.

"The beast tide is coming!"

"Get up, the beast tide is coming!"

The architectural planning of Tomorrow City is very strict, the residential buildings are all built in the same area, the military camp is built near the residential area, and the orcs who beat the gong quickly turn around and wake up all the orcs in their sleep.

The orcs have a foundation of military training, from hearing the sound of gongs, getting up on the bed, dressing and putting on shoes, and flying arrows, in less than a minute, they have turned into straight orcs in green military uniforms, and stood outside the dormitory, lined up neatly, without the slightest panic.

They did not have guns, and the guns were kept in the arsenal, and after they were assembled, they were led by the captain and quickly marched to the barracks and school training ground.

Allen's place of residence was also in a residential area, and after being woken up, he also ran towards the city wall at great speed.

Candles lit up all the residential buildings throughout the city, and the orcs who had not joined the army had no intention of sleeping, they wanted to go to the barracks, to the city walls to see how things were going.

However, the city wall did not have their share, so they could only go to see the orcs in the barracks set off en masse.

"Hurry up, your dad is going on an expedition, take a look at it now!"

"Mom, I want to join the army too!"

In many families, the children shouted loudly and were stopped by their mothers.

However, there were more and more ordinary orcs around the gate of the barracks, and some people even saw that Alan was also in the barracks.
