Physics The Greatest Magic

John reappeared on top of the sand, thanks to deprehendre, he could see the centipede's movements and figure clearly. 

The only problem now was... 

"Getting out of the ground..." John muttered 

However, his worries were quickly misplaced as the sand underneath his legs began to pull him in 

[It's coming] 

"I know." Said John before shadow stepping 5 meters away 

As he did, a the head of a giant centipede came out of the area where he was standing. Seeing as how it missed the centipede continued to move and was about to engulf it's head back into the sand when all of the sudden 

"Nolite indurare" The Area where the centipede was aiming for suddenly turned into rock, making it slam it's head straight into it. 

*Slam* 

But even with that impact it looked unfazed and simply crawled backwards back through the way it came out of. 

Seeing this, John turned the sand where it was retreating into to rock, but had no luck, it was going down the same hole it had come out of, and there was not enough dense sand in the hole. 

Seeing this, John shadow stepped right in front of it, before he muttered 

"Saint-Class ice magic: Cavea principalis densa glacies " Translation: Dense Ice Cage 

Four ice walls rose around the giant centipede, forming a big cube. After that, Spiky ice pillars extended from the ice walls before heading straight towards the centipede to pierce it. 

However, on contact with its skin, the pointy edge of the ice pillar broke and the centipede successfully managed to retreat back into the sand pit 

"... I knew it'd be hard but..." 

[Looks like the only weakness is in it's mouth... Alright, we'll end it in this attack.] 

"I guess I'll go for the head." Said John as he stood still and acted like he didn't know where it was 

He was trying to bait the boss by making him think that he was vulnerable, and it didn't take long for it to bite the bait. 

"Serena, Ariel are you ready!?" John shouted as he looked up 

He hadn't checked on them earlier because he was focused on the centipede, but now that he was able to check, A grin was formed on his face 

"If I'm not careful... those two may end up passing me" 

[Bold of you to assume that they already haven't.] 

They hadn't replied and seemed completely imersed in their spell, even for John, to do a spell like that alone would be insanely difficult. 

Suddenly the shaking on the ground got louder and louder, it was heading straight to john from underground 

"It's here" John muttered as he jumped up 

Following his jump, the head of a centipede with it's opened mouth came out of the ground. 

John cast both 'levite' and velox but made sure to stay close to him so that it could think that it was about to eat him any second. 

[Just a bit more...] John muttered 

He was getting closer to the spell which was formed in front of the two girls, and the centipede was still rising from the ground 

[How long is this thing...?] 

"NOW!" John shouted 

The instant he shouted those words, the two girls unleashed the spell, despite being big, it was fast, if John didn't shadow step away right before he shouted, he would've been hit from point blank, and he definitely wouldn't have survived. 

The spell was amazing to look at even from John's perspective. A giant red lance with a spinning wind drill at the tip. It seemed to have 5 fire arrows around the tip, and all of them had air particles gathered in front of them 

A spell this complex, was something not even john expected, they had really surpassed all his expectations. 

The centipede with no time to react or avoid the attack, was hit from point blank. The lance entered through it's mouth before the inside of it's body started to enlargen 

"Ignite!" The two girls shouted 

Seeing as how it was litteraly about to explode, john quickly shadow stepped next to the two girls before from an ice sphere around them 

*Boom!* 

Pieces of the centipede, were scattered all around the area evaporating upon seconds after doing so, and in the middle of the Sandy field, all that remained was a yellow stone. It was covered in blood but that evaporated shortly after. 

"You two okay?" John asked as he looked towards them 

"Of course, why don't you try to imitate this one too?" Serena asked 

"You won't be able to imitate this one" Said Ariel with a proud look 

[Eh? Are they mad at me because I mixed their concept with mine?] 

"Oi, don't forget who taught you two chant-less magic in the first place!" 

"That's like saying the story that we wrote is yours because you taught us how to write..." Said Ariel 

[Ugh, she has a point... How'd she even thinks of such a good example? Also I was the one, who taught you about the explosive technique in the first place...] 

John let out a sigh before propelling them and the platform downwards to the bottom 

"Alright, I won't try to imitate it." 

"Huh? I who said you weren't supposed to?" Serena asked 

"We want to see if you'll be able to, if you can we'll just make the next one harder to copy." Said Ariel with a confident smile 

"Huh? Really?" 

"Yeah? What did you think we meant?" Serena asked 

[I thought they were mad at me and thought of me as a guy who was stealing their idea.] 

"Exactly what you said." 

"What's that supposed to mean?" Serena asked 

"Nothing..." 

"Tell us..." Said Ariel 

"Haha, take a guess..." 

As the three continued to talk to each other, John was reminded of the premonition he had. It was obvious that it was something which was supposed to happen in the future, and at their current point. Serena and Ariel were already very strong. 

So just who.... Who could've been able to damage them as much as they did?
