A fortress in the usual sense is a defensive facility, built to hold a dangerous place, with multiple defense systems, sufficient self-sustaining capabilities and troops—this is a fortress. The so-called mobile forts, strictly speaking, are not compatible with the traditional definition of forts. After all, this is a large-scale facility that is clearly designed and manufactured with the intention of attacking. In terms of purpose and tactics, the so-called mobile fortress is more similar to an aircraft carrier, a mobile forward base. It's just that this aircraft carrier is amazingly large, and it also has heavy armor and large-caliber heavy guns that are not usually found in aircraft carriers, and in terms of these attributes, the closest thing to a mobile fortress should actually be an aviation battleship like the old Imperial Japanese Navy's "Ise" and "Hyuga".

It has the function of being a forward base, but in its bones it is the old style of big ships and giant artillery, which is the true appearance of the monster that is not a deer or a horse, a mobile fortress.

In the history of another world, the war experience and ending of the air battleships were not very good, and the two Ise-class air battleships had no record worth mentioning at all except for the "Kita" operation, which transported supplies to the Japanese mainland, and in the end they were blocked by the Mi Oni in the Kure Port base camp, and the last bit of blood of the combined fleet, including the only remaining Haruna of the King Kong Four Fools, was blown up and sunk. After the war, except for the "aircraft-carrying cruisers" of the Soviet Red Navy, no one ever played this kind of four-like monster. Tracing back to the source, what the so-called aviation battleships are going to do is a question that no one can say, even if it is Maozi's eight-class aircraft-carrying cruisers, their positioning is also used to expel NATO anti-submarine aircraft, covering the Red Navy's huge nuclear submarine fleet (the Kuznetsov class is no exception, its positioning is still an aviation cruiser with air defense, anti-submarine, and anti-ship missions, and the real aircraft carrier of the Red Navy is the unbuilt Ulyanovsk) to go to sea to fight. And the "aviation battleship", which is inferior to the battleship in terms of firepower, air defense, and armor protection, and the performance of carrier-based aircraft, the number of carrier-based aircraft, and the recovery capability is not even as good as that of the escort aircraft carrier, can come in handy on the battlefield where the opponent completely controls air supremacy, I am afraid that even the initiator IJN himself will not be able to say. In the end, it ended up in a flash in the pan, and it can only be said that this ending was doomed in the design stage.

In the final analysis, trying to create a "universal weapon that can do anything" within a limited tonnage and budget is itself a delusion that will do twice the work with half the effort. History has proven countless times that this kind of "panacea" weapon, which is a knife at one end and a fork at the other, will inevitably end up in a clumsy end. Although the Ise-class air battleships nominally possessed battleship guns and carrier-based aircraft, they could not be recovered through the flight deck after takeoff, and their effectiveness was greatly limited, and the smoke exhaust from the tall superstructure and chimney in front of the flight deck seriously affected the take-off operations of the aircraft, and the operation of the battleship guns was also restricted. Recognized as a failure. The same case can be learned from the F-35 fighter. Even the US imperialists, who are not short of money and have mastered core science and technology, have finally turned out to be a "fat electric machine" with their ambitious "Joint Strike Fighter" program, and in addition to the consistent trickiness of arms dealers and the Senate on Capitol Hill, its design concept of "one fighter to conquer the world" is also the bane. Not to mention anything else.

But if it is this world of Wilt with magical powers, and if such a thing as "the fortress flying into the sky" is not a fantasy but a reality, everything is a different matter.

Even warships can fly into the sky, as long as the problems of output and internal space allocation are solved, even if it is an oversized brick flying in the sky, it is not an incredible phenomenon. The technology has been around for a long time, and when the technology develops to break through those nodes, the leap in performance will naturally come naturally. In the final analysis, the "navigation of floating fortresses with propulsion devices" is nothing more than an enlarged doctrine of large ships and giant guns, far from a tactical change, but the visual and psychological impact it brings should not be underestimated.

Not to mention -

"It's actually a thunderbolt?"

Lieutenant General Kemp was surprised by the results, and for a moment he thought it was a mechanical malfunction, or that the observation department on duty was drinking during working hours, but he quickly realized that this was the only plausible explanation.

The charge of the artillery shells of the defense forces is TNT, and even if it encounters an open flame, it will only burn slowly and will not explode like picric acid or nitrocellulose, and under normal circumstances, only the detonator fuse can detonate, so it is called "safety explosive". Due to the strict quality control of the military production system of the defense army, it is absolutely impossible for the fuses of different models, batches, and calibers to have problems. The only plausible explanation is that the fuse detonated prematurely with the intervention of some external force.

This external force is the lightning technique.

"Does a high-voltage lightning strike cause the fuse to detonate early? This is a bit troublesome, if the lightning strike technique spreads throughout the fortress, the particle cannon will also cause the particle beam to be distorted or scattered due to the interference of the electromagnetic field, and it will not be able to effectively hit the fortress at all. ”

"But how did they achieve that output?"

The adjutant asked puzzledly:

"With their level of technology, how is it possible to do this?"

Even the Defence Force's own mobile fortresses still have to make compromises between the three performance indicators of protection, mobility, and firepower, and achieve a balance of overall performance by sacrificing some indicators. Charlemagne made such a thing that could fight and carry, like MT. It's incredible.

Unless—

"I'm afraid that the surface protection of that fortress is quite fragile, and the interior is all hollowed out to fill the Celestial Crystal. ”

Lieutenant General Camp sneered, once he was seen through, he was as powerful as a mobile fortress, and he was just a paper tiger. Maybe this paper tiger still has the ability to bite, but what is there to fear when you have a flamethrower in hand?

"Mjolnir ready to launch! Notify the fleet above to get out of the way!"

"The enemy fortress has a high-energy reaction, this is ...... It's a strategic-level attack!"

"What?!"

The Tactical Intelligence Officer had only time to let out a soft cry before the calamity struck.

"The technique worked well, the mana filled, and the critical value was reached. ”

The main artillery officer turned around to report, Marshal Vauban who was sitting in the command seat nodded slightly, the white-haired old man's empty eyes stared at the warship in the picture, and then looked at the thunder light that was constantly moving in the other interface, and a rage that seemed to burn everything was stirring in the empty pupils.

"Launch. ”

The majestic voice of the old man echoed in the deepest part of the fortress, and the high-ranking magicians in robes chanted the final passage of the spell together, and the blue-white ball of light that had already been gathering momentum bloomed with a strong light that had never been seen before, and the next moment disappeared into the other side of the sky.

Footage from the light-based broadcast cast a dazzling light in the command room of the City of Condors, illuminating not only the lavish décor in the style of Charlemagne's royal family, but also the three coffins behind Vauban – two of which have been closed.

The main cannon of the City of Condor "Beak of the Condor" is a 1200mm spherical lightning cannon, and the muzzle is laid with 12 super-large celestial crystals dedicated to activating strategic attack techniques. So this super cannon is also essentially an electromagnetic cannon.

The ball lightning formed by surgical interference is mainly composed of high-temperature plasma, which is very light, and the muzzle velocity is as high as 5 kilometers per second after acceleration through the electromagnetic orbit, although there is no mass, and the accompanying kinetic energy killing effect is very slight. However, it is not a weapon that relies on kinetic energy to achieve a destructive effect.

After conquering a distance of 15 kilometers in 3 seconds, the 1.2-meter spherical flash smashed firmly on the starboard side of the light floating cruiser Münster. The 120mm-thick main armor didn't survive even a second in the 18,000 degrees Celsius heat, and the part that came into contact with the high-temperature plasma evaporated and vaporized, neither steel, body tissue, nor ammunition could delay the footsteps of the high-temperature sphere, until the orb that emitted lethal light and heat drilled out of the port side and plunged headlong into the distant ground to explode, and black smoke and flames erupted from the large hole in the hull. The out-of-control light cruiser carved a dying twist course through the air before finally crashing to the ground like a broken sword. The sound of the massive crash and the crooked metal skeleton stretched for kilometers away, and the deathbed wails of the crew who failed to get out of the battleship in time were too small compared to the soul-stirring roar that made people think blankly.

"Ming...... The Münster is sinking!!"

The Tactical Controller's voice was pale with panic as he finished speaking, and the twisted wreckage of the Münster exploded entirely, the flames of the detonated munitions erupted from every crevice, and the blast wave sent the metal free from the shackles of the frame and welding and burst in all directions. Countless fragments of smoke and flame drew black parabolas in the air, falling in pairs of terrified eyes, and huge black mushroom-like clouds soared upward. The horrific spectacle resembles a volcanic eruption

The entire battlefield fell silent for a moment, except for the muffled operation of the floating fortress and the flames of the Minster's charred black keel, with the occasional wail of the collapse of the metal skeleton. Seconds later, the position on Charlemagne's side erupted in earth-shattering cheers.

Countless Charlemagne soldiers shouted with their helmets and hats, and the more daring ones even ignored the threat of enemy machine guns and snipers, jumped out of the trenches, straightened up and saluted the majestic air fortress.

At this moment, all the depression, unhappiness, and depression of Charlemagne's soldiers were released, the enemy is not invincible, as long as they have enough advanced weapons, Charlemagne's people can also press the pointy-eared ghost animal to the ground and rub it.

For the officers and men of the defense guards, although the fall of the Münster was not demoralizing, it was really imprinted in their hearts, especially those fourth-class citizens whose will was not very strong, and the numb minds of the original stagnant water caused a ripple at the moment of the crash of the battleship in the air. It won't be long before this subtle change will be revealed in subsequent battles.

Now, what the defense forces have to do is not to take care of the psychological state of fourth-class citizens, and after a short blank period of thinking, humiliation, anger, and vindictiveness boil together.

"Let Kishel and his men get out of the way and get down to business!

Vice Admiral Camp gave the order categorically, and a minute later, the order was transmitted to the bridge of the flagship Goeben, causing an immediate uproar.

Camp's original intention was for the First Cruiser to target the ground assault corps, while also protecting them from the impact of Thor's hammer. And despite the discomfort in his heart, the commander of the garrison of the fortress was still concerned about the overall situation and the face of the air force, and did not say anything stinging in the telegram. But when the fleet commander, who had just lost a battleship and was still a little dazed, received this message, his reaction was like a slap in the face. In his opinion, this is a humiliation from friendly forces, a mockery of the poor performance of the air fleet, which can only be washed away with the blood of the enemy. If it weren't for the coordination between the military forces, and the imminent launch of Thor's hammer, the fleet commander, who almost burst his blood vessels, would definitely have taken a vengeful battleship and the "Condor City" to the end. After clutching the communication message for a moment, Vice Admiral Kischel gritted his teeth and ordered the fleet to turn.

"Why should two commanders, who are of equal rank and not subordinate to each other, be in charge of the defense of the core area of the defensive line? This arrangement, which has many hidden dangers, is neither reasonable nor efficient, and can only be regarded as the appointment made by the general staff of our army after the collective drunkenness. ”

- After the war, Parsifal wrote in his reminiscences of the battle, followed by a stroke of his pen to write a text that at first glance was completely confusing.

"It wasn't until a week later that people became aware of the hidden intentions behind this seemingly flawed appointment layout, as well as the deep context of our army's war layout. ”

Now, like many people on the battlefield, the shrewd Parsifal can only devote his energy and mind to adjusting the formation of the fleet and guarding the air.

"Actually using fortress artillery to bombard, this is really the craziest and most stupid tactic. ”

In his spare time, Parsifal dropped a slightly caustic comment, which would later become the most classic comment on the duel between the two fortresses.

"Anti-gravity decomposition bomb reloaded!"

"Artillery crew retreat completed!"

"Wind speed and temperature parameters are input, and the pitch of the gun body has been adjusted!"

"The transmission line is normal! The magnetic field is stable!"

"Final safety device lifted!"

"Mjolnir ready to finish!"

Lieutenant General Camp stared at the approaching "City of Condors" in the picture, and his granite-like voice resounded in the command room.

"Launch!"

At the same time as the order was given, the red flash tore through the atmosphere, and the shock wave and pop swept across the battlefield, and Charlemagne's soldiers standing on the edge of the trench in the distance were caught off guard by the shock wave, some broke their ribs, some broke their heads and bled out, but no one cared about these little things anymore.

The straight red trajectory sank into the behemoth floating in the air, and calamity befell with it.

The black sphere suddenly appeared at the bottom of the Condor City, 500 meters in diameter, and the mass of all matter in the anti-gravity field distorted even by the light was converted to a negative number in one millionth of a second, and the mutual attraction between the atoms and electrons that make up the matter completely disappeared, and everything was reduced to atomic dust—in popular parlance, it was wiped out.

Rocks, techniques, human bodies, ammunition – everything is like a sand sculpture washed by the waves, a phantom that melts into the sun, all of which are reduced to zero.

After 1.5 seconds, the black sphere suddenly disappeared, and the decomposed and diffused matter turned into a storm that blew around, and the people on the ground clung to the ground with their heads clutched, allowing the wind to whistle overhead, sticking to the ground to prevent it from being blown away. The mobile fortress, which had been moving leisurely, was also forced to stop by this strong wind.

As the storm subsided, the people crawling on the ground cautiously poked their heads out, and as the dust and fog gradually dispersed, their vision became clearer, and the previous cheers and joys ushered in the freezing point.

Appalling.

The air fortress that occupies the sky and looks down on all living beings has a large piece of it dug out of thin air.

The fortified ramparts, the mighty artillery, the figures walking through them, all as if they had never existed. All that was left was a whimpering, wailing cool breeze blowing through the smooth, spherical hollow.

If the detonation time is delayed a little longer, I am afraid that the entire fortress will be directly cut in two.

Even so, the blow was enough to silence the exuberant Charlemagne, who trembled with the fear of "mutual destruction" and the apocalyptic vision that existed only in imagination and prophecy with their opponents on the other side of the trench.
