System In Another World

ROAR!!

Mercphobia's body expanded and transform into a giant serpent dragon. He was exuding a very powerful magic power.

"WATER DRAGON-SAMA!!" Caramile shouted on the top of her lungs. She was extremely worried to Mercphobia.

"Don't worry, I will put him back into his senses." Jin said while looking at the giant serpent dragon.

Roar!!

Mercphobia rose in the sky as waves of water appeared above the clouds.

Jellal frown while looking at the dragon in the sky.

"This is bad..." Ur said and she know that Mercphobia couldn't control his power perfectly.

Although Jellal and Ur know that Mercphobia is powerful. It was still the first time they saw he unleash such power. A power that could destroy anyone.

"Dragon... An enemy." Acnologia muttered as he looked up at the serpent dragon in the sky.

He slightly bent his knees and jumped into the sky.

Boom!!

Acnologia rocket in front of the Water Dragon.

"I will slay you."

Acnologia body started to expand and he also transform into a giant black dragon.

ROAR!!!

He opened his mouth revealing a row of sharp razor teeth. He grabbed the Water Dragon and bite it using his sharp teeth.

ROAR!!

The Water Dragon roared angrily. Then, a torrent of water hit Acnologia's body.

Boom!!

Their power shook the ground even though both of them were fighting in the sky.

Boom!!

"Jin, what should we do? I don't think that my power could even scratch that black dragon." Ur said while looking at the fight.

"Water Dragon-sama!!" Caramile was only concern about the well being of Mercphobia right now.

Jin lifted up his hand and chopped the back of her neck.

Pak!

Jin caught her as she fell unconscious.

Boom!!

The ground shook once again and gust of wind swept out. It blow Momon away.

"Momon!!" Eclair caught Momon in her arms.

Jin looked at Eclair who was hugging Momon in her arms and said, "You need to escape now."

"What?!" Eclair said.

"I said... You need to get out of here." Jin said solemnly.

"I..." Eclair opened her mouth but before she could say anything Jin once again said something.

"You will not be able to help us here. Just leave for now." Jin said with a serious expression. He then looked at Gildarts who was watching the two dragons with wifely opened eyes.

"Hey. Can you go back to Fairy Tail with these three?" Jin said to him.

Gildarts turned his head and looked at him.

"Take Caramile, Eclair, and Momon back to Fairy Tail." Jin said with seriousness.

After a few moments Gildarts nodded at him. He know that his limit and he couldn't do anything to the dragon.

"How about them?" He looked at Jellal and Ur.

"Don't worry about them. They could handle theirself more than these three." Jin said to him.

Gildarts nodded his head and he took the unconscious Caramile from Jin.

"Jin!!" Eclair shouted.

Jin sighed when he heard Eclair. He looked at Gildarts and said, "Take her with force. I know that's it won't be able problem to you."

"Jin, why?!" Eclair said to him with wet eyes. She couldn't leave them right now but she know that she couldn't help him in this battle.

"Eclair, Jin is right. We should go now." Momon said to her.

"Hurry up! Mercphobia are receiving in heavy injuries right now!" Jin shouted.

Gildarts nodded at him and forcefully pick up Eclair in his arms. He was carrying Caramile and Eclair in both of his arms. He turned around and quickly left with his full speed.

"Don't worry I will go to Fairy Tail after I finish this problem." Jin said.

"Jin!!" Eclair struggle with all of her might. Unfortunately for her, she wouldn't be able to escape in Gildarts.

Boom!!

Boom!!

Water tornado shot down on the ground. It destroy a huge part of ground creating a large pit.

Ur looked up in disbelief. She saw an ocean of water in the sky. The ocean were throwing out a powerful torrent of water to Acnologia. While a powerful meteor shower rain down from the sky. The other part of the sky was filled with water while the other was filled with falling meteor.

"This... It's like the end of the world." Ur said in disbelief. She didn't think that there could be a being that was this strong.

"Ur, Jellal support me from this distance. Don't get to close to our battle." Jin said to the two.

Ur and Jellal nodded at him.

Jin took a deep breath and jumped in the sky.

"Merge with me, Void Dragon!" Jin transform into a huge giant black dragon.

ROAR!!

GREAT HEAVEN MATERIALIZED DRAGON SKILL!!

Dark green dragoon tattoos flashed across the sky and merge with his body.

Boom!!

A black dragon with dark green tattoos shot threw the sky and collided at Acnologia.
