Kasia adjusted the switch on the pneumatic sword to keep his temperature in a suitable range, which was also the one he could tolerate at the moment. The surgical development of the heat resistance of the arm has not yet been completed, and only half of the process has been completed, but because of the physical condition, it is still possible to use the pneumatic weapon for three or four minutes within the minimum range.

"Whew!" the red-hot sword body made a sharp sound when it touched the ice, and white steam suddenly gushed out from the contact surface between the two, and after rising to a height of several meters, most of the steam turned into a slowly falling frost powder in the cold temperature. Only a small fraction of the steam rose into the sky.

It's not a good idea, and it's only a matter of time before they rise into the sky as the steam gathers and becomes a more visible signal. Kasia hurried up and slowly cut through the ice beneath his feet piece by piece. Whenever there is an ablation sensation in the arm, close the pneumatic sword and cool the arm next to the ice. It also alleviates the accumulation of steam to a certain extent, so that it will not quickly become a conspicuous target.

From time to time, I would check the time, and when the enemy had finished searching the vacant area, he would surely think of running to the top of the hill. If he hadn't completed his plan before then, Kasia thought that his outcome would not have been very good. The firepower of ten airships was something he couldn't resist no matter what. Bullets from a cannon alone can slowly drain one's life in a matter of minutes.

The results of more than half an hour were not very satisfactory to Kasia, and the effect of pneumatic weapons was not very significant in the face of the ice that had formed for a hundred years, because of the limitations of the power used. These layers of ice are both steely and as cold as pneumatic swords themselves. It only went down another two meters or so, less than three meters away from the increasingly clear condensed lava, but the speed of the cut became weaker and weaker.

There was only a dark red light around him that had been refracted by the ice a hundred times and a thousand times, and in the sound of "snort", Kasia held a pneumatic sword like a machine, and very patiently cut through the ice under his feet little by little. Black condensed lava is right in front of you, and you can reach them by destroying the dark and cold ice beneath your feet.

Kasia exhaled a breath like a valve, exhaling all the tiredness and stress in her body. Looking up, the sky above had turned a dim color. It's evening, and it's been a few hours since I've been here.

"The enemy must have noticed it. Kasia thought, with a crisp cracking sound, the ice under his feet cracked, and he made the crack on it expand with a few kicks, and the cutting speed of the pneumatic sword became faster. The smell of a needle of sulfur broke through the ice blockade one step ahead of it, and the smell of being frozen by time for hundreds of years escaped the surroundings.

The ice was eventually cleared by Kasia without incident, and the condensed lava already had some temperature on it. Beneath the rock is a terrifying energy that has been stored up for a long time, and even a slight vibration can be felt at close touch. Taking out another glow tube, Cassia dug a small pit in the condensed lava and placed the fire gun underneath it to better conduct the electricity in the glow tube. Get ready, Kasia rises up in the tight space, dodging the sharp ice blocks that have refrozen and climbs upwards.

Halfway through, countless lines of sound waves pressed down from the sky. The sound source took the shape of a six-pointed star, enveloping him in it. The movement immediately accelerated, and Kasia's body seemed to flow up the ice pit that had been dug out, and in a short moment he was on the edge of the circular device.

Without the slightest hesitation, he took out the hexagonal prism rod on his body and inserted it directly into a hole in the device. Before the hazy white light could expand its range, an orange-red patch appeared out of thin air above the crater and smashed down on the dark blue ice. It became a hot spring of strange colors, and the light of the fire was refracted through the ice cubes, and it was like a dream.

Immediately, the cannon bullets parted in mid-air with bundles of reddish lines, and exploded first above the ice. Finely fragmented pieces of ice splattered up, and before they fell, they turned into scattered steam in the impact of the flames and heat waves from the explosion of the cannons.

The swollen fireballs eventually turned into thick black smoke, surging and rising in the onslaught of mutual attacks. The cannon bullets tore them apart again, cutting the thickness of the ice layer by layer.

"Calculate the direction of the wind and fire all the cloudburst bombs. "In the control room, a calm voice sounded.

In less than half a minute, more than a dozen huge blocks of steel were projected from the six airplanes and airships. Ignited in mid-air, the tails of the flames bent slightly in the wind, but that didn't stop them from exploding in the limelight.

The white jellyfish-shaped powder unfurled almost simultaneously, and the wind made them overlap each other into a large, gapless web, and the smoke that was billowing from below was even obscured by this color. Under the precise calculations of the analyzer, at the moment when the sky over the crater was completely covered by the powder network, several sparks flashed open.

"Boom-" The sound dispersed, all the white powder was ignited, and a huge fireball smashed into the inside of the crater like substance. The power of the explosion was exacerbated by the sunken geography, and the fireball was catalyzed by its own impact and heat after a few seconds, and a huge pillar of fire rushed into the dull blue sky, and the transparent shock wave spread from the top of the mountain, like a bullet into the air cavity created by the water. The impact even regained its shape on the thunderclouds below, and a huge wave of ripples centered on the mountain rushed to all sides, and after two or three thousand meters, it completely disappeared. The thick thundercloud was almost dispersed and pressed down to a height of more than ten meters, which completely neutralized the force of the impact at close range.

The mountain shook, and the ice cracked and slid downward. But the attack did not stop there, and in this brief time, all six airships unfolded their steel decks for camouflage, revealing several neatly staggered rows of bomb holes on their sides. The bomb peeked out of the flames from the emhole and slammed into the source of the pillar of fire below.

The expanding flames seemed to have a chemical reaction, as if they were also shattering in the explosion of the bomb. At this time, the pillar of fire finally turned into a mushroom-shaped cloud of smoke, unfolding layer by layer, rolling towards the higher heavens.

"80 per cent 、、、 70 per cent 、、、、 、、、、50 per cent of ammunition remaining"

"The remaining 30 percent is set aside for backup, and the rest is all launched. When the smoke cleared, I didn't want to see anything intact down there. Il's words interrupted Silkian, and he stood at the window with a glint on his face, quietly watching the scene below. It's like admiring a famous artist's paintings in a museum, and there is indulgence and unconscious joy in your eyes.

The tiny sky was lit up by firelight, and a layer of blazing red was plated on the rocks and airships at the top of the mountain. The blast of the explosion disrupted the wind, the smoke mingled with the flames, tearing and merging at the same time in Il's eyes.

"Thirty percent of the ammunition remaining!" Stian's words fell, and all six airships stopped attacking, only the faintly red muzzles and the cooling sound of the bomb launchers "sizzling" in the wind, as if they were reminiscing about the roar they had just had.
