Physics The Greatest Magic

"Intermediate Combined Fire and Wind Magic: Causa Satani ventus malleo!!" The two simultaneously shouted. Translation: EX-PLOSIVE WIND HAMMER!! 

*BOOOOM!* 

The loud sound of an explosion followed by a giant shockwave and gust of wind passed through the whole room. 

There was so much wind pressure that John felt like he would\'ve been blown away out of the Arena if it wasn\'t for the fact that he could use wind magic. 

Both Serena and Ariel who were closest to the explosion, seemed to have some sort of wind barricade around them which stopped the pressure from blowing them away. 

Master Sylvia on the other hand, was the only one that didn\'t use magic and took the pressure on. But despite being hit by it, she wouldn\'t move and kept a poker face on as the Air flowed through the hair. 

She looked unfazed from her perspective, but from john\'s perspective, he felt bad for her hair and quickly formed an Air bubble around the two of them. 

John then quickly looked over at Master Sylvia once more to see how she was doing. He then noticed that her hair tie had come off, it was most likely due to all the wind pressure. 

[Master Sylvia without her pony tail looks just as beautiful as always] 

[Do you prefer older women?] 

[Can you stop with the weird questions?] 

John then noticed that Master Sylvia\'s suit was unharmed 

[I wonder what sort of suit that is... Even after getting hit with all that air pressure, not a single cut was formed.] 

Master Sylvia wore some sort of special body suit outfit which covered her whole body, it seemed to be some sort of special armour. 

John first saw it a year ago, but john didn\'t ask because of privacy and also because she never asked much about him or the fact that he could use magic without chanting. 

The dust cloud which was formed from the explosion was starting to disperse, and everyone\'s attention was on John\'s party 

The shockwave and wind pressure also reached them, but it looks like they all managed to hold on somehow. 

He could even hear a few words despite being all the way on the other side of the bridge 

"Woah... Those girls did that? Just the two of them?" 

"An attack like that... It was my first time ever seeing something like that..." 

"I couldn\'t hear the name of the spell from here, but it was probably king class..." 

The adventurers in the lady\'s party muttered amongst themselves 

"Can you guys quiet down?!" The lady asked as he stared closely at smoke 

Most of the smoke had dispersed and no sound was coming from the Oni, and just when everyone thought that it might\'ve died, they could see it\'s legs, it was still standing 

"Damn... That wasn\'t enough to beat it?" 

"Makes sense, it\'s impossible to one shot an A-Rank monster unless you have king-class or above." 

"Nope, it\'s finished" Azure interrupted with a smile 

Once the smoke cloud had fully disperesed, everyone could see it, and the sight they saw left them speechless. They had mistaken the ogre for having been left standing, but in reality, the only thing that was left, was it\'s legs. 

The entire top half of the torso all the way to the head had been blown off, and a pure purple magic stone could be seen 

While everyone was surprised, the bottom half of the torso suddenly evaporated and all that was left was the pure purple stone. 

It\'s size wasn\'t big but John could feel the a great amount of magic power coming out of it. 

Serena and Ariel then casually walked over to the magic stone before picking it up and raising it into the air. 

When john saw this he suddenly started to laugh 

"Haha... hahaha, those two really have improved." He muttered with a smile 

He then dispersed the air bubble and walked over to them, Serena who saw this as she slightly raised her hands to cover her mouth 

When john reached them, Serena was the first to speak 

"Hm~ So, john, do you have anything you want to say?" Serena asked 

Ariel also looked at John expectantly 

"Yeah, Good job you two." 

"Is that it?" Serena asked 

"Perhaps I may have been a little unreasonable in the past... But just know I never underestimated you two." 

"Ho~ Ariel, do you have anything you wish to say?" 

"Fufu... John... What I have to say is..." 

John was starting to get nervous by Ariel\'s sudden change and mischievous smile 

[What is she planning?] 

"Nothing, as long as he understands." 

"You\'re too easy going, Ariel." 

"Right back at you." Ariel responded with a smile 

"What\'s that supposed to mean?" 

"Nothing~" 

John watched as the two continued to talk and then turned to see if the other party had already started coming 

[Shouldn\'t they be more worried about keeping everyone waiting? Well I guess it\'s fine after that long fight.] 

[It\'s not healthy to talk to yourself] 

[Do you have a grudge against me?] 

[Not at all] 

The other group of adventurers were already crossing the bridge and heading to John and his party, meanwhile John had lost track of master. 

After looking Around for a while, he found her at the door leading to the next floor which had just opened, she looked deep in thought. 

Almost like she was lamenting over something. Although John really couldn\'t tell because her expression rarely changed, he was lucky to get to see it a few times, but the number of times could be counted with his hands. 

"Serena, Ariel, that spell you used, what was it?" 

"Oh that? It\'s combination of two intermediate spells fire and wind, also the explosion spell you taught us." 

[Explosion spell? So I was right... They used hydrogen and ignited it with the hammer on impact... A complex spell like that...] 

"Wait did you just say intermediate spell?" 

"That\'s right, Although out combined Saint-Class spell would have been more effective, it\'s too consuming." 

"Oi... Wait a minute... There\'s no way in hell that was an intermediate level spell." 

[That must\'ve been saint-class at least, right?] 

[I told you, talking to yourself is bad for your health[ 

[Zestari, that must\'ve been saint-class, right?] 

[Better, and not quite. The power output would be comparable to the lower King-Class spells. But it makes sense, if you merge 2 saint-class spells, that would naturally be the result.] 

"Really? I thought that was intermediate..." Serena muttered 

"Then what rank is it?" Ariel asked 

"Lower King-Class." John replied 

The two had a shocked look on their face 

"Why do you look so surprised...."
