In fact, the principle of modern artillery is not complicated, the firing pin on the bolt hits the primer of the gun, ignites the firing barrel, the cartridge burns and pushes the shell forward, and begins to rotate and accelerate along the rifling.

The moment the shell is pushed out of the barrel by the ultra-high chamber pressure, it begins to autobiograph rapidly, and flies forward at a speed of kilometers per second.

The excess propellant erupted from the barrel, a huge flame rose into the sky, and the air waves roared at the muzzle, and a shell flew towards the target in a volley.

The development of the earth's civilization for hundreds of years still continues this simple principle, but it is just that the value of each link is constantly improved on this principle.

Promote material science, promote metallurgical forging technology, and finally make the barrel stronger, which can make the entire gun withstand greater bore pressure and increase the range of the gun.

Study chemistry, improve the combustion performance of gunpowder, make the gun's propellant more efficient, increase the power of the shell tenfold and hundredfold, make the artillery more powerful and have a longer range.

Precision machining makes the entire gun more accurate and less incorrect. This allows the entire gun to remain more stable when firing to achieve higher accuracy.

Modern artillery can easily fire shells at enemy positions 20 kilometers away, and the explosive power of each shell is enough to shake the opponent's position.

Because there are no such high war requirements, until now, the self-propelled howitzer units of the Irlanhill Empire are still using old weapons and equipment.

Older models of howitzers do not have automatic loaders, they rely on manual loading, so the rate of fire is relatively slow.

There is no way, who makes the need for war less, and most of the defense budget is robbed of ...... by more new troops?

Even so, the 155mm caliber self-propelled howitzer of the Irlanhill Empire is still the latest, strongest and most standard weapon of war, and its roar represents the will of the Irlanhill Empire!

The fuse of each shell is verified by the puppet on the automatic production line, and each one is produced by standard parts according to the most standard process, and the pass rate is close to 100%.

Robots are not lazy, so they can guarantee the absolute quality of the product. Whether it's the raw material or the production process? There won't be any problems.

What is the product produced by such a standard assembly line? It is reassuring, but also desperate for the enemy. Every cannon? Every shell? Even every grain of gunpowder is a product that has been rigorously inspected and qualified, such a war machine? Every detail is perfect.

With an order from the commander of the gun, a huge flame erupted from the muzzle of this long-barreled 155 mm caliber self-propelled howitzer? All of a sudden, the entire artillery position began to shake? Blown dust obscured the sky.

At the same time, another howitzer next door also spewed flames, and that flame rolled in the air until it was obscured by dust? It's still expanding and jumping.

Three battalions of 155 mm howitzers? A full 54 howitzers roared in turn, firing 54 shells into the enemy's position in one go, and the power would definitely make the opponent doubt his life.

The soldiers of the Rock Empire stationed on the city walls did not know that someone had already begun to attack them more than a dozen kilometers away from them.

These soldiers are still standing loyally on the city walls, with spears in hand? Look out at the woods in the distance. At their feet are heavy walls, and the outside of the walls? It was a densely packed tent next to each other.

About 15,000 members of the Holy See's Holy Church are stationed here, plus 10,000 soldiers from the Flame Empire who have come to help.

Such a huge army? Coupled with the earth-destroying Celestial Sword weapon, the Rock Empire can be said to be strong this time......

"Yo ......" long and sharp sound of breaking the wind? Makes a Rock Empire soldier standing guard frown? Did he hear the voice getting closer? I don't know what it is that makes such a strange sound.

He listened until a dark shadow suddenly fell beside him, striking the wall beneath his feet with a muffled thud.

Before he could look down to see what had fallen, the impact fuse ignited the high explosives contained in the shell.

The explosion engulfed the soldier standing guard at once, and then the rapidly expanding air current, swept through countless shrapnel and rubble, instantly shredding everything that stood in the way around him.

The stout wooden ballistas, cut directly into pieces of wood by the air current, carried the metal shrapnel stuck in them, and rampaged the soldiers at the head of the city on their backs.

The soldiers who were directly hit were basically left with nothing left, and the soldiers who were slightly closer were now left with stumps and severed arms.

And these remaining stumps and severed arms are now also turned into flying fragments that kill and injure others, sweeping away the soldiers who are farther away.

The slender cuirass was easily pierced by shrapnel, and blood splattered everywhere. The screams continued, only to be drowned out by another explosion in the next second.

"Boom!" Another explosion sounded in the city, and the shell blew up the entire roof of the building, and the brick wall collapsed in the explosion, and all the soldiers stationed in the house were buried under the rubble.

"Fire from above! Heaven...... Raging fire! An officer watched in despair as a section of the city wall was hit directly by a cannonball and then collapsed in an explosion, muttering words that only he could hear, and staggering as if he had lost his soul.

There were many more soldiers who were so frightened by the sight that some of them even dared to kneel on the ground and beg for mercy, begging the gods to forgive them.

However, it was clear that no one could hear their prayers, and the three artillery battalions, which were more than a dozen kilometers away, were continuing to reload and fire at this moment, and had no intention of stopping.

The entire city was already covered in artillery fire, and some of the city walls were directly hit by cannonballs, collapsing into ruins and ruins.

The earth shook, and as soon as the cry sounded, it was crushed by the sound of the explosion. The whole city seemed to be ruined, and everywhere was a hellish sight.

Back then, the soldiers of the Arrant Empire only lasted a short time under the attack of the old artillery of the Irlanhill Empire, and now these poor people of the Rock Empire naturally collapsed faster in the face of the 155mm caliber howitzers that had long been different.

A cannonball whistled and landed in the camp of the Holy Cult, and the explosion blew off several tents at once. The soldiers of the Holy Cult Army, who were still singing and dancing to celebrate the victory one moment, flew into the sky the next second.
