Physics The Greatest Magic

Shortly after they were done with farming, they decided to head back, John planned on eating a reasonable amount, so that he would have enough energy to fight, and not start puking everywhere if he was hit too hard. 

On the way back, he also began thinking of a plan. Now that he had posession, and could use the dark version every element, he would most likely win in a magic fight, but this was a no rule fight. 

Master could simply shadow step away from everything he would throw at her, so there was three options. 

The first option was to restrict her then finish her off. Which was easier said than done, as she could withstand gravity x 30 and possibly 50 which was the highest john could do, before collapsing due to magic exhaustion 

[I need to think of a new restricting spell...] John thought to himself 

The second option was a close quarter fight, putting pressure at close range, even while she is shadow stepping away, however, before, john had no confidence at all, that he'd be able to win in a close range fight 

But now, John could not only use, possession, but also, Shadow step and the dark version of 'fulgurationem' Lightning flash. 

John had only learnt Lightning flash, a few months ago. At first he was looking for a spell to increase his speed. That was when he came up with the spell. 

Fulgurationem, worked in a simple way, John managed to come up with it, a few days after the incident, but it was much harder to pull off then he had expected. 

By converting his magical power into energy for his chemical energy store in his body. His body will have more energy available to use. With that energy, his body automatically had more energy transferred to his kinetic energy store with each movement. 

Causing him to move and act faster. However, that was only the first part of the spell, He would then have to speed himself up, even more by converting more of his magical power into kinetic energy. 

After accumulating enough energy, he would be able to much faster, but at the same time, it would put a major strain on his muscles, as too much energy would explode out at once. 

On his first try, John's right arm broke, and the rest of his body felt so numb that he couldn't move for a whole day. 

His body couldn't withstand all that energy, he needed to find a way, to prevent all the energy from bursting out. He needed to be able to contain it, and freely move it throughout his body. 

No matter how hard he tried, he couldn't think of anything. Then right as he was about to give up, in the middle of training in a thunderstorm, John saw thunder strike a nearby tree. 

The moment he saw that, Hope returned to his eyes, and he got the idea. A way to freely move the energy through his body. 

The human body can conduct electricity, and it has cells which are specialised in doing so. That was what his teacher had taught him in school. As he remembered that, he started another test. 

He did the same process as before, and when he had accumulated enough kinetic energy and chemical energy in his body. He then transferred some of his magic and the kinetic energy and chemical energy, part by part, into his electrical energy store. 

After that, he would just conduct that electric energy through his body, and it worked. At first, it wasn't giving him much of a boost, but after he learnt how to properly conduct it through his body, he gained super speed, He could even easily outspeed master's teleportation. 

However, there were a few problems. The first was that it would only last two seconds, the second was that, whenever he'd use it, master would instantly teleport away, and the third, was that it was too risky. 

Conducting electricity through his body was dangerous. If he slipped up, and it passed through the wrong places, he would die. On his first try, he nearly had a heart attack and was afraid to practice it for a week 

Eventually he gave up on improving it, and only used it as a last resort when he's in a very bad pinch, it's one of his forbidden spells. However, Dark lightning, He feels like mixing darkness, an element which is resistant against magic, may be able to make it harder, for him to get a heart attack 

But it may also be difficult to conduct it through his body. He wanted to check, but master, was here with him, and he wanted to save it for the fight. The shadow wasn't able to properly use it against him, so maybe there was a reason why. 

And then came the third option, a trump card john had been improving in secret, to one day beat his master. It was his best bet at winning, and master had no idea it existed. 

"John, we're here." Said master 

They were in front of an entrance to the cave. Without wasting any time, they walked inside, and found, Serena and Ariel, awake playing around with magic, with master's brother watching over them 

Master's brother didn't talk much, and always had a grumpy expression on his face. John thought that it was a shame, because he looked like a lady-killer when they first met. 

"John, master welcome back." Said Ariel as she waved at us while she continued to mess around with a small wind sphere formed slightly over her hand 

She seemed to have mastered a few high level wind spells, but john didn't know much of it. At school, she would only use chants and was pretty good at memorising them. At first she had a few problems but over time, she managed to fix them. 

Master nodded 

"Thanks" John replied 

"Did you go hunting?" Serena asked 

She didn't look like she was in a bad mood, but both her and john felt awkward talking to her after that little fight. 

"Yeah" John replied as he raised the dead bunny 

He had froze off it's wound, after it was struck by the wind bullet, so blood wasn't dripping out 

"Good" Said Serena as she got up 

She then walked towards john, surprised, john was about to step back, when all of the sudden, she walked right past him to the entrance. 

"What are you waiting for? We have some supplies in the carriage, I can't get them alone" Said Serena 

"You mean cooking supplies? You're going to cook?" Asked John 

"What else would I mean? We got the from the nearby village recently, remember?" ASked Serena 

[Serena's cooking... I wonder what that's going to taste like...] 

John was looking forward to it. 

"Be careful you two" Said Ariel with a smile as she waved at them
