Dancing Circles on the Horizon of Events

E = 1/2 mv ^ 2

This is a formula in classical physics for calculating the energy a moving object has.

Now, here, multiple stone blocks, roughly 500 kg per stone, which occurred when Demon King's Castle was blown up, are drawing parabolas and about to fall into Vixen.

Is the maximum speed to reach the ground 250 km/h, etc.?

In other words, the energy of the stone mass at the moment it falls to the ground is approximately 15.6 MJ (megajoules).

If energy could have been taken out entirely, it would be equal to heating 1 t of water by 3.7 degrees (100 degrees with 37 kg of water).

... then here is the problem.

What happens to an adult man weighing 70 kg when such a stone mass is hit?

... the answer is, I'm sorry for 'hurting'.

"Wow!!

"also, no more..."

"Oh, here too?!

People in havoc before the rain of debris pushing from the sky.

Even though he was in the labyrinth where he was evacuated until earlier, the next moment he was suddenly exposed to the danger of his life in an abandoned town.

Exactly, isn't it in a water state on your sleeping ear?

... Well, that doesn't exactly seem to be the case.

In the meantime, one block of stone was approaching her, still young, town daughter, straight into the ground.

"Huh!"

A girl who manages to avoid it but has lost her hips and can't stand.

"Ha, help me..."

The blue sky that was visible from the girl's eyes is rapidly covered with gray, and the township that was running around with you and your friends becomes invisible at the same time.

Even if I desperately tried to move my hands and feet to avoid them... in a body that didn't move as strongly as I wanted, there was no sooner left to escape the stone mass than there was no one around to help me.

If your eyes were anointed with gray... the next view you see isn't red... it could be black.

The girl thought about that before the impending stone mass... meditated her eyes hard, then finally tried to squeeze it out of the back of her throat and mouthed the words.

"Help... demon king...!

Dogowong!!

And that sound rang from the neighborhood...

... except I heard that sound... from the girl's own ear.

"Wah, Master Waltz! If it falls, please tell me it falls! I thought I was going to die..."

After the explosion, the voice of a woman, accustomed to hearing it since she was little, enters the girl's ear.

"No, because? Something small (...) stone (...) was going to hit people, and I'm not waking up well unless I save a life I can save... or I can't face Catalina, and I'm going to be cursed..."

"Sister... Catalina, how do you think about your sister...?

"... research bugs"

"... yeah... right..."

Now I hear the voices of women I don't know.

I was wondering if this could be the (...) world (...) of the (...) side (...), when the girl opens her horrible eyes...

"... can you stand? If you can stand, hurry and evacuate to safety."

... one day, a longing demon king who wanted to be so himself, was reaching out against himself.

"... I hope I collected this, but what do I do?

Waltz, who took all the debris he was about to fall into the city of Vixen, asked Lucia.

"Should I blow it up? Yeah, fine."

Dogowong!!

... Lucia releasing words and then releasing magic particle beams without intermittent hair.

"... something, we're running out of charge time, aren't we?

"Hmmm... I don't know!

"Oh, yeah..."

If we could give that extra magic a little bit to Leah, she might go full speed..., etc., waltz showing her face in Lucia's magic.

Together, the treatment of debris ended without difficulty in the form of evaporation.

"Well, then, that troublesome creature next..."

"That's disgusting..."

Lucia speaks frankly to an organism with a mouth like a goat eel (watch out for browsing when searching).

"What is it? That demon."

"Come on... Isn't that you? A neoplasm that came out of the labyrinth. If so, around Catalina, I'd be happy to start an autopsy..."

"Wow..."

Apparently Lucia imagined Catalina chopping up the creature with joy with some dark grin, giving her a sincerely unpleasant look.

"So, that, you can take it down, right?

When I tried knocking it down, it was a natural monument - just in case it doesn't mean something like that, I'll ask the top (Yuki) of the country waltz.

"What... you know... how do you take it down?

Yuki had no idea how to fight a demon nearly 1 km long.

Perhaps in her head, it's not about fighting, it's about how to miss a citizen.

"Huh? It's not easy. Lucia? You can do it because it doesn't seem like a protective animal or anything."

"Huh? Are you sure?

"In the simplest and most useless way possible, please."

"Ugh, yeah..."

Lucia smiled for a moment about getting permission to fight from her sister, but, unexpectedly, it was hard to come with an order, so she ended up with a rugged look on her face.

But while she's worried, it doesn't necessarily mean the giant creature won't be in the next act, so she decides to defeat it in the most useless way she can think of right now.

"... So this is it?

Dogowo!!

Strong winds flow through the surrounding area in the direction of the presence of giant organisms.

... except that Lucia didn't use wind magic.

They used metastatic magic to move giant creatures.

At that time, there was a so-called explosion in which air flowed all at once into about 150 M (mega) litres of space where the organism had disappeared.

So where did that giant creature disappear to?

Dogowong!!

... a giant creature that showed up trying to cover and hide the still high western sun.

He (?) was relocated to about 2000 m above the fields that Lucia herself had blown away.

In short, Lucia would have thought of causing damage by letting it fall, without using extra magic.

... sarcastically calculated, would it release approximately 47 kt (kilotons) of positional energy in TNT conversion if a giant organism still in a falling state fell to the ground?

In other words, the magic particle beam that Lucia tried and unleashed (?) Coarse destructive force or more energy on the ground...

"Wait a minute, Lucia! That's awkward!"

Waltz exclaimed, imagining a phenomenon that would occur when a mass weapon fell to the ground, extending to 10 GT (Gigaton).

"At least... uh... if you don't let it transfer to a position less than 300m, it'll be worse than the magic Lucia used before!

"What...!?

To my sister's point, Lucia has a startling look on her face.

"Well, then, soon..."

With that said Lucia turned her hand toward the demon.

Gwow!!

With that chirping, the demon disappears again.

"What...?

Lucia, who somehow raises a question about how such a demon looks.

"... what's going on?

"... vanished on its own"

"What..."

Apparently, Lucia didn't use metastatic magic.

... and where the demon reappeared...

Gwow!!

... just above the waltzes (over Vixen), it was a 1000 m place.
