Multiverse selection 1 Fairy Tail Karna

After beating the crap out of Gerard, Karna turned around to find everyone alive with a few having been weakened due to continuous battles. He used his magic to scan their conditions a bit and found out that most of their harmful wounds are healed and what's left are a few scratches here and there.

But what confused him the most was the look they were giving him. Other than Cana who had an apathetic look as if she had seen this every day, all the others were wide eyed and some even gulping in fear. Some even seemed to be giving pitying looks to now beat up Gerard.

"Why are you all looking at me like that?" Karna asked a bit confused.

No one seemed to be saying anything, suddenly Lucy stepped up and asked.

"Don't you think you went a bit too far?" She asked with an awkward smile.

Karna sighed.

"Alright now, let me give advice to you idiots." He started while pinching his nose in frustration.

Then started the lesson of Karna which included a lot of advice on how waiting for your opponent to finish is a waste of time, waiting for your opponent to power up is the most idiotic thing and how making sure that your opponent stays down permanently is one of the most important things to do in a fight.

For two hours Karna covered all the taboo's in anime fights. he also made sure that they know how to not let their opponent pull of a last-minute strengthening and ruin everything that they had done till then.

He had no idea that his comments actually resonated with them making all of them be more decisive in taking down their enemies. But that also indirectly led to their increase in public property damage, excessive destruction and many more which will later make Karna slap himself in the face.

"So, what should we do now?" Erza asked while looking at Gerard who was now kept inside a card.

"For now, we need to break this tower completely so that no one can use this tower in any way ever again."

"But what about the pieces of the Ethernano?, the chances of aquatic life being mutated when it falls into the sea is very high" Erza said out her concerns.

"Plus, there is a chance of it exploding as well" Gray provided his input.

"Don't worry about the explosion part, it only happens if the magic runes on the centre node of the tower gets destroyed. The magic circles are in a way responsible for changing the volatile attack of the ethernano cannon into solid ethernano.

If I edit the runes a bit while dispelling a few others, I might be able to make the ethernano in the tower more stable while making sure no problems happen when the tower is destroyed.

And the pieces that fall into the sea, I can handle it, though Juvia it would be really helpful if you use your water magic to make sure all the pieces are brought to a more central location."

"Juvia will try her best to help Gray-sama' s friend" Juvia said while jumping towards Gray, making him scream in fear getting a laugh from all others.

From then on, the next few hours included Karna modifying the entire tower on his own. Erza's old friends were extremely surprised at the ease in which he was editing the tower as being one of the people who were included while the tower was build, they knew the complexity of the magic circles in it. The fact that someone was able to see the circles once, understand it, edit it, and change it into something which was not possible for the hundreds of researchers who were building it was astonishing.

"Alright, I'm done" Karna replied as he put the last set of runes.

"""SO FAST""" the others had wide eyes seeing that.

"All right Natsu, do your best."

"Hehehehehehe, don't worry breaking stuff up is a speciality of Fairy Tail wizards" Natsu Said with a grin while flames appeared on both of his fists.

At the same time Gray used ice magic to make gatling guns to destroy the structures. Lucy summoned Taurus and Erza summoned heaven's wheel armour and used multiple swords at the same time.

Erza's friends were not able to help much since their magic was not centred around destruction and was mostly tactical and support based.

While at the time, Karna was able to do a thorough scan on Gerard or now called his true name Jellal and was able to find out the manipulation magic placed on him.

The others were shocked when they found out and Erza was glad to find out that her friend is still there and was not a complete psychopath of his own free will.

While he did an even more intensive scan on the manipulation magic and found out traces of celestial magic in it.

'So, our resident taboo maker might have been in charge of making sure Jellal kept the R system running.' Karna thought.

'By now he might have returned to Grimoire heart with the mass of cursed energy thinking that it was the key of resurrecting Zeref.

The mass of cursed energy made by accumulating the negative emotions of people who suffered while making the R system tower. I gotta make sure to get all of them when I take them down.'

By now everyone managed to destroy almost all the parts of the tower while Juvia combined with the sea managed to collect every piece of Ethernano that was a part of the tower before.

I then used the storage given by the system and made sure to take every last piece of Etherion with me. The research I am going to do with it is going to be very helpful, especially when we go to Edolas. Even though I have physical stats that can make sure that I will survive, its nice to have a way to use magic.

A/N- hope you like it and every 100 powerstone get extra chapter of Jason.
