Physics The Greatest Magic

"Guys how many have we saved?!" John asked 

"24!" An adventurer replied 

That meant that 30 were left, John had his arms full keeping everything in tact, but despite it being draining, Ice used a lot less magic than the earth wall. 

"You! There's no mermaids near the left side of the platform, get as many people as you can, focus on that side" John shouted as he pointed at the guy closest to the left side 

"I'm on it!" The guy shouted before jumping in 

"Focus on backing him up! We're saving all of them, every single one!" John shouted 

"YEAH!!" Everyone shouted out 

John had been leading them by giving them directions but it was no longer needed, everyone already knew what to do 

Those who knew water magic, were using water spells to get there faster and carry the people out in a water ball, and those who had other elements, such as Wind, Fire, or earth, were the ones attacking the mermaids which tried to get closer and supporting those who went over to save the others. 

Although some fire mages were a little useless in attack so they instead chose to swim over and do it by hand. 

This was john's plan, simple yet effective. 

"3 mermaids went past the right side of the platform!" John shouted 

He could easily keep track of the numbers and pinpoint them accurately with Deprehendre. Not only had many already made it past the platform, but they also managed to grab on to a few people 

But when that happens... 

"I'll go deal with it! Watlon take command!" Shouted John before jumping into the water 

"Understood!" Watlon replied 

Once john was in the water, he propelled himself towards the mermaids. They had grabbed on to 3 people and were dragging them down to the bottom, but the fact they they all moved together made them a lot easier to deal with. 

Not only that, but since they were mostly concentrated on the off shore, and all of the people they needed to save was on the near-shore, john wouldn't have to fight or save many at once, which made saving them much easier 

[Possession] 

John had to be fast, possession was exactly what he needed 

John then shadow stepped In front of the mermaid, before she could even react, he stabbed her and cast 'Glacio'. She froze from inside out, in an instant. 

The only explanation to that speed was because they were in water. 

John then grabbed on to the person who was drowning and formed an air bubble around that person's head. 

He then left the person for a while and show stepped on to the next mermaid who still within range and froze her before placing an air bubble on the person's head 

John then propelled himself over to the last person and repeated this process. 

When he was finished, john grabbed on to all three and propelled them straight out of the water 

*Splash! * 

The sound of water being splashed everywhere resounded as john propelled himself straight out of the water like some sort of dolphin. 

And while he was in the mid-air falling down straight towards the platform all three of the people he saved. 

He began to fake chant and cast a wind spell to lower and weaken the fall 

Since they were taller than john, the only way he could hold on to them all at once, was by making them all hug each other. 

As he dropped down, he laid on the ice for a while before getting up, it was cold, but john was using thermal magic to make it feel warm. But in exchange, he had to increase the ice's durability so that it wouldn't melt 

"W-Woah..." An adventurer muttered 

Everyone was looking at john as if he was some sort of idol, the skills he displayed was amazing. 

"What are you guys doing? Focus! We still have more people to save!" Shouted Watlon as he focused on covering for some of the guys who were swimming to get more people 

As he got up, he noticed someone amongst the adventurers who he hadn't seen before, a blue haired man, wearing a white heavy armour. 

But before asking anything, john went straight into helping those who drowned 

He placed them side by side, and dropped to his knees beside them. 

As he placed his hands over their mouth, he began to fake chant. Shortly after, he pulled the water which had entered their lungs out of them. 

He then began to gather oxygen in his hands and split it into three parts before putting it through their mouth. 

The knight watched but he couldn't comprehend what he was watching. It wasn't like normal healing magic, and simple advanced healing magic wasn't enough to heal someone that has drowned as for some reason, even after the wounds were fixed, the person wouldn't wake up. 

Only Saint-Class or above healing magic could fix it, but what this boy in front of him was doing wasn't any of these. 

Richart had taken an interest on this young boy. 

A light then formed under johns hand and he manually increased the three's heart rate so that blood could start to flow normally through the body. 

After that... 

"*Cough* *Cough*" The three started to cough and temporarily woke up but fell back asleep after 

However, that was a good sign, it was happening to everyone john would heal, it might've been the after effect of being hypnotised, before drowning. 

"They're saved!" 

"This little boss really is something special..." 

"If it wasn't for him, all of these people would be dead..." 

Richart who saw this, decided to talk to john. 

"Hey young man." Richart called out to john 

"Yeah? I'm sorry I'm a little busy right now, if it's not something important, can we talk about it later?" John asked as he looked over at the left side and front 

3 fallen mermaids were coming in from the left while 5 were coming in from the front 

John would be able to deal with them all at once but he was feeling a little fatigued, and wouldn't be able to properly control the output. He could end up hitting innocent civilians with the attack. 

Not to mention how, his strongest attack was a fire spell which would have no effect, so in reality, there wasn't anything he could do against them 

[Want me to handle the rest?] Zestari asked 

[…] 

[I'll attack where they're concentrated directly. You don't have to worry about others getting hurt.] Said Zestari 

[Can I leave it to you?] John asked 

[Sure, but only for this attack, I won't be able to maintain your ice platform like you.] Said Zestari 

[First let's get everyone out of the water, then I'll pass it on to you.] Said john 

[Understood] 

"No, I simply wished to ask if I could assist you, I'm a magic swords man knight, and I'm quite good at using the holy element, which is their weakness." Said Richart 

"Thanks, I'd appreciate it if you could." Said john before walking to the edge of the platform 

He couldn't let zestari take over yet, there were still around 10 people left in the water, but 8 mermaids were coming. 

[What do I do? If I handle them individually, I won't be able to save everyone...] John thought to himself 

Suddenly, a holy glow was coming from behind john, when he turned to see what it was. It was richart's sword. 

It was glowing a bright yellow colour as he raised it up to the air 

"Don't worry, this won't hurt the civilians, it's only effective against monsters." Said Richart as he walked over to the edge 

John watched as he swung his sword down and said the words
