As the dark yellow sun gradually set in the west, the first line of ground lost by the Principality of Lucerne coalition in the town of Kodor ushered in a convoy of luxuries.

"I've seen Her Royal Highness the Princess. ”×N。

A group of Imperial Army officers led by Brigadier General Solo saluted Princess Roni who got out of the car, and Princess Roni returned the salute, "You have worked hard. ”

"Don't dare to be, it's all for Your Majesty and the Empire. Brigadier General Solo replied modestly.

After a burst of unnutritious official words, Princess Roni took the initiative to ask Brigadier General Solo to take her to the coalition army's position.

When she came to the position, Princess Roni jumped into the trench and looked left and right as if she was curious, and when she passed by the anti-artillery hole, she bent down and drilled in, and Brigadier General Solo, who came with her, asked strangely: "Your Highness, what are you ......?"

Princess Roni didn't answer directly, but asked rhetorically, "What do you think about the position they left behind after fighting the Duchy of Lucerne army for so long?"

Brigadier General Solo pondered for a moment before replying: "It is a very simple but practical fortification, which can greatly enhance the survivability of unprotected infantry and increase the difficulty of the attacker's attack, especially the barbed wire arranged in front of the position, coupled with a large number of automatic weapons, it is simply a nightmare for the attacker's infantry, especially the weakening of the fire crystal cannon, but it can't stop the shooting of the soil howitzer." ”

Princess Roni asked again, "Presumably you will encounter such fortifications in future battles, what will you do then?"

Brigadier General Solo replied confidently: "Use the gravity projectiles of the earthen howitzers to destroy all the enemy's fortifications, and no fortifications can resist in front of the powerful gravity bullets." ”

Brigadier General Solo poured a basin of cold water on him as soon as he finished speaking, "What if there are no howitzers or not enough shells?"

"It's ....... Brigadier General Solo, who was still patting his chest just now, broke out in a large cold sweat on his forehead, because he couldn't think of anything other than to use howitzers.

Princess Roni shook her head in disappointment, large-caliber earthen howitzers and gravity shells are complex to manufacture and expensive to build, and the number of equipment in the entire Imperial Army is not much, otherwise in the Duchy of Lucerne, her Ninth Front Army would not have waved south because it could not capture the trench area of the coalition army, in fact, Princess Roni has always had an idea in her heart, that is, to use the armored force assault to break the trenches of the coalition army, but unfortunately the current magic tanks of the Imperial Army are still only experimental products, and the number of tanks of the Ninth Front Army is not as large as the howitzer, and only the Ninth Front Army has it。

Princess Roni has written a detailed report on the advantages and disadvantages of the magic tank on the battlefield and sent it back to China, believing that the alchemists of the Phoenix Empire will improve the current magic tank, or produce more powerful magic tanks.

This time, Princess Roni brought all her tanks with her, just in time to use the offensive and defensive battles in Kodor Town to test her ideas. But before that, her mind was on how to deal with the coalition trenches more effectively.

Princess Roni asked Brigadier General Solo to collect a large number of domestic animals, put them into trenches, anti-artillery holes and machine-gun forts, and then brought in a variety of light and heavy weapons to shoot at the trenches to test the damage of the existing weapons of the Imperial Army to the trenches and inside.

After several hours of detailed testing, Princess Roni got satisfactory data, the most useful weapon for the trench system in the current arsenal of the Imperial Army is naturally the gravity bullet fired by the soil howitzer, followed by the city breaking projectile fired by the earth howitzer, the so-called city breaking bullet is actually a high-density earth magic element crystal, cone-shaped, very hard, and straight ballistic, mainly used to attack strong objects such as fortresses and city walls, and the machine gun fortress is not much different from the eggshell if it is hit by a city-breaking projectile, similar to the armor-piercing bullet on the earth。

Then there is the enchantment bullet of the wind system, the principle of the enchantment bullet of the wind system comes from the enchantment of the wind king in magic, after the magic bullet hits the target, it will shoot hundreds of small wind blades to the surrounding 360 degrees without dead ends, and it can effectively kill soldiers hiding in the trenches, with a killing diameter of fifty meters, similar to the shrapnel on the earth, and the firing device is still a large howitzer, so Princess Roni wrote a proposal to the military industry department of the Phoenix Empire, suggesting that the general magic crystal cannon that can fire various magic cannonballs can be studied.

As soon as the sun rose the next day, the Imperial Army was already preparing for the attack, and the coalition forces naturally did not sit idle and began to make intense preparations after discovering it.

At seven o'clock in the morning, the Imperial Army began to attack, this time it was still the magic crystal cannon to wash the ground, the fire cannon and the earth howitzer raised their thick barrels one after another, firing red and yellow-brown magic cannonballs, and the coalition positions were instantly covered with explosions and smoke.

Three kilometers behind the second line of positions of the Gallic coalition army, a 1902-style 76mm field gun of Ouyang Yu's army was opened, and a total of 48 Type 1902 field guns were operated by hundreds of artillerymen, and the muzzle of the 1902 field gun was aimed at the direction of the magic cannon of the imperial army.

Two kilometers behind this artillery position, there was also an artillery position, and twelve 1904-style 152mm-200P cannons with a range of up to 14 kilometers were also raised high, ready to deliver a fatal blow to the enemy.

These fifty-two artillery pieces were temporarily purchased by Ouyang Yu last night, after seeing the bombardment of the Imperial Army's gravity bombardment on the position of the coalition army, Ouyang Yu gritted his teeth and bought these artillery, which was used to counter the Imperial Army's magic crystal cannon, as long as the Imperial Army's magic crystal cannon was destroyed, the soldiers of the Imperial Army's position could only use human lives to pile up.

"Target No. 1, four degrees to the right directly ahead, at a distance of seven thousand three hundred meters, charge No. 2, triggering the fuse, target No. two, three degrees in front of him, at a distance of 11,500 meters, charge No. 3, charge No. 3, triggering the fuse, one test shot!"

The artillery observers reported the direction and distance of the Imperial Army's cannon group and howitzer group, and the gunners of Ouyang Yu's army quickly shook the high and low planes of the artillery.

"One shot test shot, let's go!"

"Boom!"

The 76-mm field artillery group and the 152-mm cannon group each fired one shell, the field artillery group against the Imperial cannons, and the cannons against the howitzers of the Imperial Army.

"Whew...... Boom!"

After the screeching of a speeding train, two shells landed accurately in the cannon and howitzer groups of the Imperial Army.

"Test shot, rapid fire, rapid fire!"

"Boom, boom...... Boom, boom, boom......!"

Ouyang Yu's field artillery group and cannon cannon group let out an earth-shattering roar together, and one after another the cannonballs fell into the artillery group of the Imperial Army, because the cannonballs shot by Ouyang Yu's army were not like magic bullets, they would neither shine nor shine, so the unsuspecting artillery of the Imperial Army, together with the magic crystal cannons they operated, were buried in the sea of fire.

"What's going on?!"

Princess Roni and Brigadier General Solo's hidden command post was not far from the fire cannon group, and they and the staff staff in the command post were frightened by the sudden continuous explosion, and Princess Roni ran out of the command post and saw the location of the artillery group like a volcanic eruption at first glance.

"Our artillery group is finished. ”

Although Princess Roni couldn't see the falling shells, she knew very well that it was definitely the enemy's tactic, otherwise why the explosion was only where the two artillery groups were located.

The ten-minute firing of Ouyang Yu's two artillery groups completely wiped out the two artillery groups of the Imperial Army from the ground, and then turned the muzzles of the guns and launched a bombardment towards the assembly point of the Imperial Army.

Different from the high-explosive shells used in bombardment artillery groups, the best shells used when bombarding unprotected infantry are shrapnel, which have thin walls and contain high-performance explosives, as well as small steel balls or steel arrows, steel balls, etc. The warhead is equipped with a timing fuse, which can explode over the predetermined target or explode after hitting the target, and can carry out greater damage to the enemy's living forces. Howitzers, field guns, anti-tank guns, tank guns can all fire such shells.

Infantry can also lie down to dodge when encountering high-explosive shells, but the shrapnel that explodes in mid-air is not only useless, but will also increase the area of the bomb, and the shrapnel can shoot hundreds of small steel balls or steel arrows at a single explosion, because it is an air explosion, the killing area is large, and the infantry within the killing range has no possibility of survival.

Ouyang Yu's army's fifty-two Soviet-based artillery pieces and eight German artillery guns fired thousands of shells in just half an hour, most of them were howitzers, and the more than 20,000 soldiers of the imperial army who initiated the attack had no defense, as well as their artillery comrades, after dropping thousands of broken corpses in the face of Ouyang Yu's army's shelling, they hid in the trenches left by the coalition forces and trembled with their heads, and were forced to die before the attack was launched, and their morale was low, resulting in the inability to launch another attack for a whole day.

After the shelling, Princess Roni went to the completely destroyed earthen howitzer position to check the damage, the former howitzer position is now like a hell on earth, full of bombed broken corpses, mutilated corpses, blown up howitzers.

The barrel of a howitzer was twisted by the shock wave, and the gun carriage supporting the barrel of the gun did not know where it went, Princess Roni reached out and patted the barrel of the gun, making sure that the gun was made of strong, heat-resistant metal, not a plastic camouflage toy.

Then she came to the corpse-strewn assembly site, and at her feet lay a corpse, the corpse of a hornet's nest in the true sense of the word, which was unlucky under the repeated bombardment of several shrapnel shells, and there were not a few such corpses.

"What a demonic weapon, and who are we fighting?"

A big question rose in Princess Roni's heart.
