That time I got reincarnated as a slime,no, a DRAGON?

CH-78

Hearing a voice as cute as that of a little girl, they all turned towards the source of the voice. Sitting on a chair was a cute little girl with purple hair tied in a ponytail. She would have looked way too out of place in a battlefield if it wasn't for her military uniform.

"Who are you? And how did you did you get in?" Faraga asked.

It was a logical question to ask. The airship had magic barrier not only on the outside, but also inside it. Yet, it had sensed no intruder. Not only the barrier, but no one else even noticed her till the time she spoke up.

But it was a foolish thing to ask. Even if his question was logical, the being in front of him, Ultima, was someone way beyond what logic could describe.

"So you don't have any for me? Well that's alright. I can take tea as well. By the way, my name is Ultima. It is a ve~ry important name given to me by Rimuru-sama, so remember it, alright?" Ultima said as she tilted her head cutely.
"Stop messing around. Tell me what you are here for?"

Faraga's mind was still in a turmoil, but the fact that he could still control himself and make logical decisions just shows how great of a general he was.

"I just want to ask a few questions."
"Questions?"

Faraga was no idiot. He knew that if she managed to break through their magical barrier without them knowing, she must be a race with exceptional control over magic. The only race that came to his mind regarding what Ultima could be was a demon. And not any demon, but an archdemon. Faraga was sure that he could hold up pretty well even against an medieval demon.

"Yep. Regarding how this airship flies as well as those tanks. Oh. And also if there is anyone strong in the Empire."

As Ultima was speaking, Faraga ordered his aides through telepathy.
'Activate Magic Cancellors at full power inside the airship.'

As soon as the magic Cancellors activated, Faraga took out his gun. Unlike the guns that were mass produced and used magic, this was manufactured completely on Earth and had no use of magic. Meanwhile, his other hand was already on magic sword.

"You wanted to know who was strong in the Empire, right? Well, I am one of them."

He said as he shot at Ultima. Just as he had predicted, Ultima dodged it and was sitting on the seat of the Captain of Airship. He then took out his magic sword and thrust into Ultima. Or atleast that was what he thought.

"So you think you are strong, eh? I will kill you at the end and give you the most despair."

He heard a voice behind him. As soon as he turned around, a round mass went flying past him. It was the head of one of his aides. He looked at the now headless body standing in front of him. It took a few moments before it fell on the ground and started convulsing, as if it had forgotten all about it until then.

"Hmm? He didn't know much. Oh well. Let's move on to the next one." She said as she plucked off the head of another person. Ultima was an intelligence officer. She also knew that Rimuru was intrigued by these machines and though that getting information on them would earn her praise.

"M-Monster."
"Run"
"Aah!"

"Everyone. Summon Ifrit." Faraga ordered. Hearing this the his aides regained some of their calm and got to work. With the help of magic amplifiers and nearly 50 surviving magicians all used their magic to summon Ifrit. As there was no magicules in the air that they could use, they had all their magic that they had inside them to summon Ifrit.

Ultima on the hand, thought that this would be interesting, and hence she decided to stop. This was also another way for her to create despair in the souls of those fools who had tried to invade the land of her lord.

"Hahaha. You might be strong, but this is your end."
"Is that so....?"

Ultima asked. As soon as she said that Ifrit froze, completely covered with ice. Unlike the Ifrit that Shizue had a pact with and could summon at any time, this Ifrit was summoned directly from the spirit realm, and hence required a lot of magicules to summon.

"Mou.... And here I thought you would summon something interesting, but this is quite disappointing." She said as Ifrit broke into millions of pieces.

"Well, let's get back to the interrogation."
"How? Th-There is no way a demon like you without any magic can defeat a high level spirit. Not that easily."
"Without magic? Is that the effect of the Magic Cancellors? Sorry to disappoint you, but it has no effect on me." Ultima said cutely.

"No effect?"
"Yep. You see, to us demons, magic comes as simply as breathing." As soon as she said that another aides head flew off.

"See? There was no sonic boom as I used magic, Buuuut.." her fingers blur for a moment and another flies off, followed by a large noise and wind pressure.

"If I obey the rules of physics, I can create a sonic boom and use it to attack as well by going faster than sound. Well, there was something called hyperphysics that Rimuru-sama told me about, but I cannot use it properly yet."

Hyperphysics, as mentioned by Rimuru was something that worked on the loopholes present in physics itself. To cover these loopholes, the world itself takes action. Understanding these special actions of the world and how to use them is called hyperphysics.

"Huh?" Faraga couldn't understand what he was being told. It appeared to him as if Ultima was speaking some foreign language.

Before Faraga could even understand what was going on, Ultima had proceeded to massacre everyone on the airship except Faraga. The only reason that the airship was still in the air and not on the ground was because Ultima was preventing it from crashing.

"Well then, as I promised, I will kill you now, at last." Ultima said smiling. It was only now that Farag realized just how scary a smile could be.

"Well, Rimuru-sama told us to go all out. Well, here ya go." Ultima said as she threw a black ball at Faraga before teleporting to Gabiru and taking him away from there before he would be harmed.

The black ball that was thrown to Faraga was hellfire. It was flames born out of uncontrollable chaos fire, found only in hell. Thousands had tried to control it, even his master Gadra tried, but failed miserably. But now, a demon right in front of his eyes had managed to accomplish this feat.

As soon as this hellfire went out of Ultima's influence of control, it started spreading rapidly, burning anything and everything in its path. Faraga's body started burning from the inside out and the unimaginable pain of being burnt spread throughout his soul.

The main Airship blew apart into pieces. The larger parts of the hull crashed into other airships taking them down with it. Many smaller parts rained down on the battlefield ensuing chaos amongst the Imperial soldiers. The monsters on the other hand could use this to their advantage as they were continuously supported by Benimaru.

This marked the end of the Imperial Flyin Corps.
