Physics The Greatest Magic

As soon as he did, he felt a shockwave, pass by and all the windows around him cracked. 

"What... The...? What happened?" Zakaragi asked as he looked around 

One by one, people started to drop to the ground, while others remained motionless as they stood up. 

The guards didn't drop but they were staggering as they began walking towards the water. 

[What's happening to them?] John asked 

[Their minds are being manipulated. Those who were knocked unconscious were lucky, those who stayed standing, are going to drown themselves.] Zestari replied 

[I know that, but why?] john asked 

[Look over at the water.] 

John did as she was told, and when he did, his eyes widened. 

There was a horde of fallen mermaids far off shore, Ray couldn't fully count as some submerged themselves in water, while others stayed above. 

"Oi... John, what's happening?" Zakaragi asked once more 

"The beach was hit by a full-scale mermaid attack..." 

After john said that, he quickly turned towards the umbrella where Serena and Ariel were at. 

There was a dark sphere in that area, which was big enough to cover, their whole group and a few others. Seeing this, john let out a sigh of relief 

"Master made it in time..." John muttered 

But now was no time to relax himself, as he spoke, there were people slowly walking towards the water. 

"Zakaragi... Listen carefully, go over to the dark sphere with Wilma and keep her safe. Okay?" john asked 

Zakaragi who heard this nodded 

"Let's go wilma" Said Zakaragi as he stretched out his hand 

Wilma who saw this then jumped on to John's arm 

"Hero, where are you going?" Wilma asked with a worried look 

"Hm... Hero is going to save the day, which is why, hero needs you to follow big brother zakaragi okay?" Said john with a smile 

"Okay..." Wilma muttered as she let go 

She then walked over to zakaragi and grabbed on to his hand 

[Zestari, is it safe to walk out of the field?] John asked 

[Yes, it was a shockwave attack which already passed through. However, from the looks of it, they're preparing another attack.] 

[I see...] 

"Zakaragi, go now." Said John as he deactivated the anti-sound field 

The sound field stopped sound from coming in, so the moment, john deactivated the field, the sound of a screech could be heard coming from the ocean. 

Zakaragi ignored that sound and started to run off towards the dark sphere with Wilma. Meanwhile, John was on his way to the ocean. 

Once he reached the shoreline, he looked around to see how many people were hypnotised and moving towards the water. 

And the amount was shocking, it was half of the people who were on the beach, and judging from what john could see, it was in the 200s 

The shoreline extended from one side all the way to the other, the beach was big. 

[Zestari... Do you think I could create a wall big enough over the shoreline to prevent people from passing through?] John asked 

[… That is impossible.] 

[…] 

[For someone normal. You can try, but if you fail and end up fainting from overusing your magic power, then those who are currently swimming further into the ocean will die.] 

"As long as there's a small chance..." 

John looked back, at the where master and the group were, when zakaragi and Wilma reached it, the Dark Sphere opened up and gobbled them in. 

"Seriously... Master is so trustworthy..." John muttered as he placed his arms on the ground 

"Verum Resurgens terra..." Translation: True Earth Wall 

Slowly, sand and the earth under it, started to rise around the beach. 

Instead of covering the whole shoreline, John simply made half a curving wall rise around the shore line. It curved and formed Half a circle if you looked at it from above 

And as it continued to rise, john felt like chunks of his body was getting dragged out of him. 

"Come on... Nearly done..." John muttered as he poured every ounce of his strength into it. 

Then just as he was about to throw up, he was done. 

John collapsed on to the ground as he started to pant. 

"I'm never... doing... that again..." 

He then threw up on the sand 

He washed his mouth with water he created from aqua and looked around. He was surprised that he actually managed to pull it off. 

He wall which stretched out over 50 meters and curved at the end, so that the people who were hypnotised couldn't just go around it, but instead, would have to go back and around. 

If you looked at it from above, it would look like the half of a circle was covering the beach. Not only that, but the walls were over 3 meters high and reinforced... 

John watched as those who were hypnotised, bumped their faces on to the earth wall consecutively. Thankfully, it had sand in it to soften the impact and was reinforced so that it wouldn't break apart. 

[Since they're hypnotised, do you think they'll think about going back and around?] John asked 

[…] 

[Zestari?] 

[Curving it was a good idea... while hypnotised, some may not be smart enough to think about going all the way around. But it's not too soon to celebrate, you only covered around 75% of the people, the others are either already swimming or weren't put inside of this circle you created.] Said Zestari 

"So now it's time to save those who've gone swmming huh..." Said john as he created a small exit to pass through so that he could get to the water 

[You won't be able to save everyone] Said Zestari 

[I know that...But I'll still try to save as many as I can] John replied 

[…] 

As john was about to leap straight into the water, someone stopped him 

"Where do you think you're going without us?" 

It was a very familiar voice, 

"You're not forgetting your party members now, are you?" 

John turned around, and it was his 2 close friends, Serena and Ariel, and behind them. There were around 20 others 

"Who are they?" John asked 

"My name is Watlon, like some of the others you see here, I'm an adventurer and a magician. We'd like to help. With all honesty, I first planned on escaping with my family, but when I saw you create that wall to help everyone, I was moved. Will you please allow us to help you?" He asked 

A tall man with long red hair which stretched down to his shoulders and red eyes. John felt like he'd be reliable, and all the others as well. 

"Of course, but... With all of you here, i have a plan which could save as many as possible. Does anyone mind if I suggest it?" john asked 

Even if he was strong, he was still a kid, for an operation like this to be led by a kid... 

"Of course not!" 

"Tell us what to do!" 

"You're the boss, kid!" 

John who heard this formed a small smile 

"The plan is simple..." 

*** 

"I see... With this we should be able to buy enough time before the royal knights arrive." Said one of the adventurers 

[Royal knights?] 

[A special group of knights who deal with large scale, dangerous attacks against a city or kingdom. It's obvious that a city like this would have one. They're strength is on par with A-Rank adventurers, and their strongest members are on par with S-Ranks.] Said Zestari 

"I can't guarantee you guys will live... This plan is a bit risky..." Said john 

"Huh? Who cares about that?" 

"We're adventurers we spend years risking our lives" 

"And if this is successful, I'll be able to drink and boast about it all day." 

"That's right. We're all aware of the risks, so don't worry." Said Watlon 

"Is that so... Then... Let's move out" Said john 

"Yeah!" They shouted as they followed behind him 

With 25 mages, john wasn't sure whether his plan would turn out successful. To save 50 people who were most likely already drowning in the water while going against over 40 fallen mermaids. It was a big risk, but risks were all part of being an adventurer 

"How the hell did things turn out like this.... Can't the kingdom be more safer or buff up the security around the beach?" John mumbled
