As the war raged on the 'Fairy Tail' world were currently training as they knew of what the outside worlds were capable of. They had 3 more year's till the barrier lowered and they would be forced to fight against the other worlds.
=====
Currently Kuro was teaching alongside the other's the army of Angel that he had. He taught them to technique and slowly they began to learn the ability.
Due to them having the Kaio-Ken and Ki control they were able to grow stronger as a whole. Although nobody reached the higher realms he still had a powerful army that could collectively used Kaio-Ken to raise their powers by a large amount and fight stronger beings.
With this, Kuro felt satisfied and he trained his own body in the meantime.
In a large Gravity chamber he sat on the floor alone, his hair was gold and his muscles had increased slightly. He calmed his breathing and attempted to turn from Super Saiyan to Super Saiyan 2 but failed. He was already pretty strong so it didn't matter. He stood up and sensed the world and didn't find anything wrong. He then further used his power to sense the farther away world where the Demon King was at.
"I can fight them...equally. But if they're army is there..." He sensed the other elites training and found their power increase rapidly.
====
The Demon king stared off into the distance where Kuro was at.
"A being can sense me from that far away?" He frowned. The Demon King only knew of a few who could and those people were around the Peak of the 9th level of the Transcendent Realm a level way higher then him.
He now knew how many monsters were going to be in this world so he began to train even harder to develop the skills he held.
A sword was currently flying above his head as he bit his thumb, a string of blood floated upwards into the sword. A dark glow of red light flashed and the sword grew in size.
With a sigh he continued on meditating to unlock his demonic bloodline to increase his power.
With this maybe he'll have enough to fight off against the other's who were now nearby his world.
"Activate Blessing" As the world will now increased so much the increase in power was relatively stronger now then before.
As the blessing began to take affect those who were about to lose received a boost in strength and they overwhelmed the invaders.
======
"Die, Fallen Angel!" A half step transcendent slashed down his holy swords towards the already heavily wounded fallen angel who used to be his comrade.
As the fallen angel was about to accept his fate a sudden surge of strengh made it possible to grab his dagger and block the sword.
"Not yet" The fallen angel said with a smirk as they both pulled back. The Angel frowned as he shot a ball of faith carrying a message towards his God. Soon he began his own fight.
=======
In another part of the world a Magus who was at the First Stage shot a beam of light at the Demons which killed them. But, as he did so to the next the demon didn't die instead it launched its own counter attack.
The Demon smirked, he soon jumped into the pile of dead demons and ate them while the Magus sent a message to all Magus to group up.
[All other Magus it is I the Leader of the First Group, the Demon has not been killed by one attack. They are now stronger please group up and dont go alone. You Will die]
As he sent that message the demon had already ate the bodys causing an evolution.
"Ma...magus...you...die" The demon said in a course voice as it grabbed a nearby sword and it launched itself towards the Magus.
"Its intelligent?!?" The Magus was surprised as it formed a barrier with his Mana. Then he used another part of it to summon missiles. With his mental strength he could use 3 spells at the same time.
He gathered a large amount of mana and he began chanting while his Magical Armor began to absorb the energy in the world and turn it into pure mana which fused into his shield to make it stronger and use it to summon mana missiles.
As the demon dodged and blocked the attack it continued to eat his comrades who had died. It also communicated with other Demons nearby to bring them here so that they could overwhelm the Mage.
As it slowly reached the Peak of the First Stage it soon stopped dodging and it began to face the attacks head first.
The Magus after a full minute stopped chanting and with a smirk he shot out a powerful blast of mana which was compressed into a small blast.
As the blast of energy was shot forth a good number of demons used various methods to summon demonic energys to attack the blast of mana.
The small energy blast grew larger and larger until it was as large as a small house which at the time was oretty large.
"Die!" The Magus yelled as it flew away with his remaining amount of mana. And due to the Gamers systems the Magus now grew with exp and after killing that many demons it grew to the third stage of the Transcendent Realm.
The Many magus grew stronger and stronger while Angels and Demons couldn't. Their bloodline stopped them from accepting that help which made them weaker but the Demons had the Worlds Blessing and the Angels also had the blessing.
The Magus however had many races living in the world that were under the Magus but they didn't clearly unify the world.
======
Kuro in the gravity chamber continued to practice his marital arts while testing out the limits of his Ki. To force his body to grow he used Kaio-Ken recklessly since he had a large amount of Sensu beans.
"KAIO-KEN" A large aura surrounded his body as he continued to train after 3 minutes his body fell to the ground,he ate a sensu bean and sat upwards.
"Mhm, I increased in strength and my kaio-ken is also growing. This is good" He said as he stared at his status board. He stood up and continued the practice.
Now that he had figured out kaio-ken times 15 in his base form up to 3 minutes he really wanted to try it on his Super Saiyan Form.
As he transformed he felt a large amount of energy in his body, he whisperd Kaio-Ken and his body didn't feel as bad. Until he reached Kaio-Ken times 10 where his body now felt like he was being crushed on.
That was merely 10 seconds in that form which made him frowned he ate a sensu bean and stood up.
"Maybe I should try something different...what about my Great Ape Form? Maybe I can control it into my base form and create a new ty-" Before he did that he found the exact thing he thought of in the system. The way to make it to this form was explained easily and he made his way to the training ground.
For the next 10 days he attempted to control his great ape form and his Kaio-Ken into his super saiyan form.
