Release that Witch Chapter 276: Development of new cannon

Lucia was on the way with ore to see His Highness the Prince, and the words Nightingale were still ringing in his ears.

I have to say that she was shocked by the calm attitude shown by the other party.

Although I don't quite understand the relationship, witch and the prince ... are impossible together? In this case, shouldn't you be careful to hide your thoughts in bottom of heart, so as not to let the other party know?

Also, why is she awkward and blushing even as a listener?

Stand at the door of the office take a deep breath, Lucia pushed in.

"Sir, I brought the ore."

"Let me see," Roland yawned.

This Border Town's The ruler looks the same as usual. The sleepy-eyed look should be just awake from a nap. He leaned on the back of his chair. His expression was natural and easy-going, unlike any other noble That's fierce.

Lucia's inexplicable tension also relaxed a lot. She took out the ore particles found in Northern Slope Mine from her skin bag, and placed one by one on her desk.

After the ability to decompose, these particles look almost the same, the color is either silver or gray, and probably only the knowledgeable His Highness the Prince can tell what kind of ore it is.

I saw the prince frowning for a long time, and put them in his palms one by one, and looked at the sunlight behind him, and finally waved, "cough cough, I will give these ore to Mr. Schuire to identify You can continue to practice your abilities in the backyard of Northern Slope. If you do not understand, please consult Anna. "

"..." Well, don't you even know His Highness? Lucia quickly bowed his head, "Yes."

When she was about to leave the office, Roland called her again.

"By the way, you got a good test this time, with 68 points in the ninth place. It's not easy to have such a table after learning for a month, and it must be maintained. And ... "He's paused." In the next test, I hope Bell can also participate with everyone. "

"Yes!" Lucia answered excitedly.

*******************

After watching the little girl bow happily, Roland sighed at the metal particles on the table.

I am still too naive. After thinking that after decomposing into simple substance, I might be able to find out which veins are in Northern Slope Mine, but the facts made him understand the huge gap between mechanical engineering and geology. These stones eventually Three to four metals will be differentiated. The one with the most remaining amount can be considered as an ore of this type of metal, but they are almost the same in color and shape. For example, iron, aluminum, magnesium, and potassium are all in high purity. Silver white metal, it is too difficult to discern with the naked eye.

Leave the problem to the chief alchemist to solve it. After all, it is more reliable to verify the characteristics of the material through chemical reactions than guessing.

After finishing this matter, Roland pulled out a piece of paper and began to plan how to deal with this year's Months of Demons.

Seeing that summer is about to end soon, three months in autumn is his final preparation time. In addition to defending the Evil Beast from the west, he must also pay attention to the east Timothy and Church. No less than the last year, the population and income under his administration have increased significantly, and the ironmaking output is gradually increasing. witch is more than a dozen, and is completely confident to turn Western Region into an insurmountable copper wall and iron wall. .

According to the combat experience of the previous year, there is no doubt that the biggest threat to the city wall is Evil Beast Hybrid(s), especially when the enemy has a heavy carapace and the bullet is difficult to penetrate, either approach dynamite or send witch out of the city to fight, no matter what Countermeasures, the danger will be greatly increased.

In addition, most of the enemies he faced were mainly cavalry and infantry, and he had not seen the seige weapon of this era. If the other party can set up a torque trebuchet or a more advanced counterweight trebuchet, I am afraid that I will encounter a lot of trouble. After all, the front-loaded cannon is very inconvenient to shoot downwards. The muzzle needs to be raised again each time it is loaded It also easily rolls out of the barrel.

It is imperative to develop a more powerful cannon.

Roland pondered and listed the indicators that he needed on a piece of paper.

First, it should have sufficient range and power to penetrate Evil Beast Hybrid's carapace at a distance of one kilometer. Second, it must be rear-loaded ammunition, which can freely adjust the elevation angle, and at the same time have the ability to shoot quickly. Finally, in order to reduce repetitive research and development time, multiple uses of one gun should be considered in the design, that is, it can be used as a fixed turret to suppress the enemy, or it can be directly pulled to the ship as the main weapon of shallow water weight gunship in the future.

So it should be a heavy-caliber, long-barreled cannon.

Roland first thought of those fifteen-six-inch behemoths on battleships, with a range of up to tens of kilometers, and could dig up several meters of chasm on the ground in one shot, but he quickly rejected this unrealistic idea. Although there is no problem in processing, based on the current material level of Border Town, at least nine of the ten guns will blow up the chamber. Even if the pipe wall is thickened to more than one meter, the created things will lose practical value because they cannot be moved. .

At present, he can only produce high-purity wrought iron and ordinary-performance steel. The plan is still conservative.

Roland finally set the caliber on the sacred number of 152 millimeters.

cannon uses a vertical wedge-type gun latch, similar to a door that can slide up and down. When it is lowered, it exposes the cannon, loads the shell, and locks after resetting upward, so that the gunpowder gas erupts forward. Compared to screw bolts and cross wedge bolts, it has the fastest firing speed, and the principle is very simple. The mechanical structure has long been familiar in his mind.

However, in order to achieve quick firing, cannon must also be equipped with a retreat and re-entry mechanism. In simple terms, it is like two pumps, one filled with oil, and the other is re-entry spring or gas. When the muzzle rear seat is pulled, two barrels of connecting rods are used to compress the oil and the re-entry machine at the same time. The oil is used to cushion the recoil, and the re-entry spring completes the force storage. After the bombardment is completed, the barrel is pushed back to the original position.

The last is the shell.

Since the Holy Grenade is used, naturally it can no longer be satisfied with the poor solid iron ball and paper-packed shotgun Roland. Due to security considerations, it was decided to develop two fixed-type artillery shells at the same time. Is a solid metal; the other is an explosive warhead with a triggering fuse, which is a later-generation howitzer. After all, the latter has certain technical difficulties, and the reliability of the fuze needs to be tested repeatedly. It is not possible to assemble the troops before Months of Demons, so it is necessary to produce the former to solve the problem. Even with a solid warhead, it is easy to deal with slow moving thick armor Evil Beast and fixed siege equipment.

Of course, no matter what kind of shell, it needs to consume a lot of smokeless gunpowder. Before large-scale production of the two acids was achieved, the new cannon could only be used as a special weapon, and impossible realized it if it wanted to play a hearty fire coverage.

At this moment, personal guard pushed the door and left come in.

"His Highness, there is a secret letter from Kingdom Capital."

Roland put down the quill and opened the envelope. The letter has no signature from beginning to end, and the handwriting is very strange, but the content of only one sentence shows that the letter was undoubtedly sent by Tasa.

A team of about 1,000 people left Kingdom Capital today and headed for Western Region. (To be continued., Your support is my greatest motivation.)
