Release that Witch

Lucia took the ore to the prince's way, and her ears still wandered around the nightingale.

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

Although I don’t understand the feelings, the witch and the prince... can’t be together at all? In this way, isn’t it necessary to hide your mind carefully in your heart and not let the other person know?

Moreover, why does she even feel as if she is a listener?

Standing at the door of the office, I took a deep breath and Lucia pushed the door inside.

"His Royal Highness, I brought the ore."

"Let me see," Roland yawned.

The ruler of Bentham Town seems to be in peacetime. The appearance of sleepy eyes should be just waking up from the nap. He leaned back on the back of the chair, and he was natural and easy-going. He was not as fierce as other nobles.

Lucia's inexplicable mood also relaxed a lot, she took out the ore particles found in the North Slope mine from the skin, one by one on the desk.

After the ability to decompose, the particles look almost the same, the color is not silver or gray, probably only the prince of the versatile Prince can tell which mineral is this.

I saw the prince frowning for a long time, one by one in the palm of my hand, and looked at the sun behind me carefully, and finally waved, "cough, these ores will be handed over to Mr. Staple to identify You continue to go to the backyard of the North Slope to practice your abilities. If you don't understand, please ask Anna."

"..." Hey, don't even know the Highness? Lucia quickly bowed her head, "Yes."

Just as she was about to leave the office, Roland stopped her again.

"Right, you have a good test score this time, and the sixty-eighth point is ranked ninth. It’s not easy to follow this study for a month. It’s not easy to keep it. You have to keep it. And..." Aaron, "I hope that the bell will be able to participate with everyone in the next test."

"Yes!" Lucia said excitedly.

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

After watching the little girl happily squatting, Roland looked at the metal particles on the table and sighed.

I am still too naive. After I thought that it would be broken down into simple elements, I could understand the mineral veins in the northern **** of the mine. However, the facts made him understand the huge gap between mechanical engineering and geology. These stones eventually Three or four metals are differentiated, and the most retained ones can be considered as ores of such metals, but they are almost identical in color and shape, such as iron, aluminum, magnesium, and potassium in high purity. Silver-white metal, it is too difficult to distinguish by the naked eye.

Or give this problem to the chief alchemist to solve it. After all, verifying the material properties through chemical reactions is much more reliable than guessing.

After processing this matter, Roland took out a piece of paper and began planning how to deal with this year's demon moon.

Seeing that summer is coming to an end soon, the three months of the fall is his final preparation time. In addition to resisting the evil beasts in the west, you must always pay attention to Tefco and the church in the east. Not in the last year, the population and income under his rule have grown substantially, and the output of ironmaking has gradually increased. The number of witches has increased by more than a dozen. It is completely certain that the western environment will become an insurmountable wall. .

According to the combat experience of the previous year, the biggest threat to the city wall is undoubtedly a mixed species of evil beasts, especially when the enemy has a thick shell and the bullets are difficult to wear, either close to the use of explosives or send witches out of the city, no matter The risks will be greatly improved.

In addition, most of the same kind of enemies he faced were mainly cavalry and infantry. They have not seen the siege weapons of this era. If the other side can set up a torsion trebuchet, or a more advanced counterweight trebuchet, I am afraid that it will encounter a lot of trouble. After all, it is very inconvenient to shoot the guns down. It is necessary to raise the muzzle again every time you fill it. It is also easy to get out of the cannon.

It is imperative to develop a more powerful artillery.

Roland thought about putting the indicators he needed on the paper.

First, it should have enough range and power to penetrate the shell of the mixed species of evil spirits one kilometer away. Second, it must be post-loaded ammunition, free to adjust the pitch angle, and have the ability to shoot quickly. Finally, in order to reduce the repetitive development time, it should be considered as a multi-purpose design, that is, it can be used as a fixed turret to suppress the enemy, or it can be directly pulled onto the ship as the main weapon of the future shallow-water heavy gunship.

So it should be a heavy caliber with a large caliber and a long body.

Roland first thought of the fifteen-inch-inch giants on the battleship. The range was as high as tens of kilometers. A shot could dig a few meters deep on the ground, but he quickly rejected this unrealistic idea. Although there is no problem in processing, it can be based on the current material level of Bianbu Town. At least nine cannons will be blown up in the ten cannons. Even if the pipe wall is thickened to more than one meter, the things created will be lost because they cannot move. value.

He can only produce wrought iron with higher purity and ordinary steel at the most, and the plan is still conservative.

Roland finally set the calibre to the sacred number of 152 mm.

The artillery adopts a vertical wedge type breech bolt, which is similar to a door that can slide up and down. When it is lowered, the cannon is exposed, and the projectile is loaded. After the upward reset, the lock is realized, and the gunpowder gas is ejected forward. It has the fastest firing speed and the principle is simpler than the screw ejector and cross wedge breech, and its mechanical structure has long been familiar in his heart.

However, in order to achieve rapid firing, the artillery must also be equipped with a retracting mechanism, which is simply like two inflators, one filled with oil, one with a reentrant spring or gas. When the rear seat of the muzzle pulls the two-bar linkage, the oil and the re-entry machine are compressed at the same time, the oil is used to buffer the recoil, and the re-entry spring completes the accumulating force, and the barrel is pushed back to the original position after the shelling is completed.

Finally, the shells.

Since the use of the holy cannon, naturally can no longer be satisfied with the poor solid iron ball and paper bag shot Roland for the sake of stability, decided to develop two fixed cannons at the same time, one is the enlarged version of the bullet, the bullet is solid metal The other is a explosive warhead with a trigger fuze, which is a later howitzer. After all, the latter has certain technical difficulties, and it is necessary to repeatedly test the reliability of the fuze. It is impossible to ensure that the troops are assembled before the demon moon. Therefore, it is necessary to first produce the former to solve the problem. Even solid warheads are a breeze to deal with slow-moving thick beasts and fixed siege devices.

Of course, no matter what kind of shells, you need to consume a lot of smokeless gunpowder. Before the two acids were not mass-produced, the new artillery could only be used as a special weapon. It is impossible to achieve a hearty gunfire coverage.

Just then, the guards pushed the door and came in.

"His Royal Highness, there is a secret letter from Wang Du."

Roland put down the quill and opened the envelope. The letter was not signed from beginning to end, and the writing was very strange, but the content of one sentence indicated that the letter was undoubtedly sent by Tassa.

A team of about a thousand people left Wangdu today and headed westward. (To be continued. Your support is my biggest motivation.)
