She looked excitedly at the condemned prisoner and waved her hand.

"Execution."

The five executioners were given the order to each of them to shake the horse's buttocks with their whips.

The horse neighed in pain and began to exert force in five different directions.

The prisoner's body was pulled with great force, and he was immediately in pain and wanted to scream, but the rope around his neck tied his throat, and he could only let out a snorting and screaming in pain.

The rope broke straight, and there was a constant sound of tension, and at the same time, the limbs of the condemned prisoner's body were also straightened with all his strength, and the clothes on his body began to "hiss, hiss!" The pull breaks.

The prisoner's face was pained, and blood coughed out of his mouth, upwards for a short distance, and then fell back on his face, down his cheeks and the corners of his mouth.

Finally, after a short period of time, only a violent tearing sound was heard, and the prisoner's body was torn apart, and his whole body was divided into five large pieces, and he died of complete pain.

On the ground, there were five pieces of the body of a condemned prisoner tied with a rope tied to it, as well as a large pool of blood.

The pungent blood filled the air, because it was snowing, and now there were neither vultures nor goshawks, and the white snow reflected the red blood, which was very distinct.

Qian Fei'er sat in the viewing position, a pair of squinting eyes had all opened, and at this time, she caressed her cheeks with both hands, her face full of enjoyment and intoxication.

Ah, bright blood...... The red flowers are so beautiful......

Her martial soul involuntarily unleashed, a pair of Heavenly Demon Horn helmets with curved upwards on top of her head, and six huge divine golden wings spread out behind her body.

It's just that at this moment, the original black fine lines on these six huge golden wings have become more and more intense, the color has deepened, and the width has also increased.

At the same time, the original Angel King Martial Soul's divine aura that was more brilliant than the sun and divine was obviously weaker, and a weak, dark, and powerful killing aura began to appear to make up for the weakened divine aura.

The Fall has begun!

Next, Qian Fei'er watched the execution process of another death row prisoner, and after watching, she put away her martial soul and returned to the Heaven Dou Palace with a few guardian soul masters with satisfaction.

This time, she didn't use her martial spirit to fly, but rode a horse, letting the horse carry her all the way back to Xuelin Palace.

Back in Xuelin Palace, Qian Linjue and the others were sitting by the hearth, and everyone was waiting for Qian Fei'er to eat.

Although Qian Fei'er told everyone to eat in advance, Qian Linjue insisted on waiting until her cousin, and the others had no opinion except for Qian Liuli.

According to the principle that the minority obeys the majority, Qianliuli's opinion was not adopted.

However, the housemaid still did not want to wait for her cousin, who doted on her, and went out by herself, and ordered the maid to make a meal and eat it in her room.

After dinner, Chiruri stayed in her room, baking the electric grill while reading comics.

The harem of the Heaven Dou Imperial City, the Xuelin Palace, and the front hall of the main hall.

Qian Fei'er pushed the door and entered, and was greeted by Qian Linjue's somewhat angry and arrogant criticism.

"Sister Fei'er, what's wrong with you? Let's sit here and wait for you to have dinner, do you know what time it is? Do you know to come back?! ”

Are all waiting for me? This......

Qian Fei'er was very embarrassed, her squinting eyes had re-squinted at the moment, she stroked her cheek with one hand, and apologized very embarrassed.

"I'm sorry I went out to deal with a little urgent matter earlier, and I apologize for delaying everyone's dinner."

As she spoke, she bowed in the direction of everyone.

Qian Linjue's face was a little worried and distressed, he stretched out his hand and pointed to the main seat where Qian Fei'er usually sits, and spoke in an arrogant tone.

"It's okay, sit down, immediately give Young Master Ben an honest meal, after dinner, you are not allowed to go anywhere, just stay in Xuelin Palace, that's all."

After the order, Qian Linjue stood up slightly upright and shouted in the direction of the door: "Maid? Serving. ”

Qian Fei'er's exclusive maid quickly came to the door, bowed respectfully in the direction of the main seat where Qian Fei'er had just sat down, and after saluting, Xiao Xiaobu took a few steps back, closed the door, and then ran away quickly.

After a while, the door opened again, and the maid and a cook brought in a large vat of boiled white and fragrant mutton soup, as well as a large amount of various bacon and beef, into the vestibule of the main hall......

Subsequently, everyone happily had dinner in the front hall of the main hall of Xuelin Palace, laughing and laughing, so lively.

After dinner, Qian Linjue and the others went back to their rooms, leaving Qian Fei'er alone in the main hall of Xuelin Palace.

In the front hall of the main hall of Xuelin Palace, Qian Fei'er sat by the quilt stove, sipping a cup of tea while thinking about the artillery in the New Year.

She has already decided to make an artillery, the principle of firing the cannon and the structure of the barrel have been determined, and now what remains is the question of the projectile.

Only, what is the projectile going to do? OK

The warhead of an artillery projectile is not the same as that of a firearm bullet, the warhead of a firearm bullet is solid, to put it bluntly, it is a simple steel or copper, and it causes penetrating damage after being fired.

The projectile of the artillery shell is different, after being launched, the pursuit is to trigger the detonation and form a large area of explosion damage, in order to pursue the maximum area to kill the enemy's cluster target, destroy its buildings or destroy people and animals.

Then, since it is necessary to trigger the detonation, it is definitely not possible to insert a lead on the projectile, not to mention the question of whether it will explode without landing in mid-air, and it is difficult to say whether the projectile inserts the lead will affect the combustion of gunpowder filled at the bottom of the breech.

In this case, it must be that the projectile breaks the moment of contact and explodes.

Such a substance, as soon as Qian Fei'er came, she thought of high explosives, nitroglycerin.

In the Middle Ages, people concocted this high explosive several times more powerful than black explosives! It is perfect for use as a weapon of war.

It's just that......

Qian Fei'er frowned.

Nitroglycerin reacts violently, not to mention contact detonation, that is, during transportation, a little violent shaking can explode, which is very unsafe.

Moreover, there is an important problem, Qianfeier does not extract nitroglycerin!

Since you can't use nitroglycerin to explode, you can only use black explosives......

Qian Fei'er groaned slightly.

Black explosives need to be ignited with fire, filled inside a sealed artillery projectile, and ignition from the outside is basically impossible.

And detonate on contact, that is, spontaneous combustion occurs at the moment of contact, or a violent reaction occurs when it encounters air.

And no matter which one it is, Qian Fei'er thought of white phosphorus for the first time.

White phosphorus, white or light yellow translucent solid. It is soft, brittle when cold, and the color of the light becomes darker. Exposure to air produces green phosphorescence and white smoke in dark places.

In moist air, white phosphorus catches fire at about 40 degrees Celsius and slightly higher in dry air.

At the same time, white phosphorus can directly act with halogens, sulfur, metals, etc., form phosphoric acid with nitric acid, generate phosphine and sodium hypophosphite with sodium hydroxide or potassium hydroxide, and can also react violently with chlorate to directly cause an explosion.

In the military, white phosphorus is most commonly used to make smoke bombs and incendiary bombs, and the famous napalm is involved in white phosphorus.

From this point of view, white phosphorus is undoubtedly the best material for making projectiles in the Douluo Continent at present, the projectile is filled with white phosphorus and chlorate inside, and the outside is wrapped with a layer of fired and fragile pottery.

Once the projectile is launched, the outermost layer of pottery touches the ground or the target for an instant, and it is directly shattered, and the white phosphorus inside touches the air, and spontaneously combusts instantly, which can detonate the black powder.

Not only that, but it can also be filled directly with chlorate inside, and it and white phosphorus are separated by a layer of partitions that are equally fragile or easy to break, and the moment the shell touches the ground, the white phosphorus can break through the partition and contact the chlorate, which can cause an explosion.

Perfect!

The corners of Qian Fei'er's mouth curved slightly upward, and she had already imagined the picture of a future war.

She thought to herself that the projectile of the shell could also be made into an elongated and slightly conical shape, that is, a spindle shape, to increase the range.

In addition, it was possible to reduce the caliber of the barrel, the volume and content of the powder chamber at the bottom of the bore remained the same, and the shell was changed to solid steel, so that it became an "armor-piercing projectile".

The large-caliber steel cannon used in ordinary ammunition has a thread on the outside of the shell, and a threaded rifling is also added on the inside of the barrel, so that the shell can rotate at high speed when it flies out, which can increase its accuracy.

Well...... Not bad!

After thinking about it, Qian Fei'er finished drinking the tea, sat directly on the spot, and meditated and cultivated.

Night, quietly passed......

The next day, as soon as it was dawn, Qian Fei'er went directly to the arsenal of Heaven Dou City, and all the government affairs were handed over to Xue Ye.

In the next month, Qian Fei'er went out early and returned late every day, and after a series of repeated trials and casting, she finally succeeded in developing the first large-caliber rifled artillery and the first small-caliber smoothbore armor-piercing gun.

Heaven Dou City, this morning, after the end of the morning dynasty, the cavalry school outside the city.

Qian Fei'er and Ge Long stood on the huge snowfield as far as the eye could see, and as far as the eye could see, there was a snow-white patch, and the edge of the snowfield in the distance looked like a wall.

This is the visual effect caused by the circle of the planet, in fact, the snow field should be completely flat.

In front of Qian Fei'er and Ge Long, there were two cannons, one large caliber and one small caliber.

Both guns had muzzle angles diagonally upwards of forty-five degrees to obtain maximum firing range.

A turntable was installed in the center of the gun carriage to adjust the angle of the gun and thus the firing distance, which was carried by two rubber wheels underneath, and two brackets with an angle of 60 degrees were installed behind to resist the recoil.

The barrel length of the two guns is about the same, about 4.5 meters, of which the caliber of the large-caliber gun is 155 mm, and the caliber of the small-caliber gun is 88 mm, and the difference in caliber is nearly double.

In addition to the two cannons, there are also two small boxes next to them, one of which contains dozens of special shells, and the other is a cylindrical solid primer and a lead.
