If Kenichi were fully dragonized, he could easily devour the Fire Dragon God's roar.
But in his current state, Kenichi probably couldn't manage that.
Bzzzt-
After Kenichi entered the different dimension, the massive pillar of flame instantly struck the ground.
The pillar of flame, hitting the ground, gathered without dispersing, forming a crimson hemispherical light screen.
That hemispherical light screen expanded continuously in all directions at a visible rate.
Once the hemispherical light screen grew to a certain size, it erupted with an extremely dazzling light.
This light even surpassed the sunlight in the sky, completely devouring everything around.
At that moment, a deathly silence fell between heaven and earth.
But what was brewing behind this silence was destruction.
Boom-
One second later, a terrifyingly loud explosion sound followed.
Accompanied by this loud noise, a terrifying air current carrying extremely high temperatures spread out in all directions like ripples.
Everything in the surroundings was utterly annihilated under the impact of this air current.
Even some small stones were evaporated by the high temperature.
Originally, Erza, Mirajane, and Wendy had already retreated several kilometers away on the magic airship.
But they were still affected by the terrifying air current.
Fortunately, the temperature of the air current decreased continuously during its spread.
Plus, there was the protection of Kenichi's runes.
So the magic airship was only sent flying by the air current, and it didn't melt like the stones.
Erza, Mirajane, and Wendy on the magic airship held onto each other tightly, struggling to maintain their balance and not fall.
The terrifying explosion came and went quickly.
After a few seconds, the air current dissipated, and the explosive flames in the distance also vanished.
After the magic airship stabilized, Erza, Mirajane, and Wendy all secretly breathed a sigh of relief.
Then, everyone looked into the distance.
They saw that the island, which had already been flattened, was now a massive crater.
Steam continuously rose from the crater.
Seeing this scene, Erza, Wendy, and Mirajane were all horrified.
They had seen Acnologia before.
In terms of destructive power of a roar, the Fire Dragon God definitely surpassed Acnologia.
Because the Fire Dragon God's roar, besides the explosion, also had terrifying heat waves that evaporated everything around.
Although Erza was still somewhat worried about Kenichi, based on their previous experience, Erza glanced at the runes in front of her.
Seeing they were still there, she knew Kenichi had avoided the terrifying explosion.
Just as Erza and the other two were breathing sighs of relief, the Fire Dragon God, whose dragon claw had been broken by Kenichi, was looking down at the crater with satisfaction.
"With this, that human should be finished, right?"
As soon as the Fire Dragon God finished speaking, Kenichi jumped out from the different dimension.
Kenichi, having already gathered all his magic power, looked like a high-speed spinning tornado.
Swirling around the tornado were six different colors of violent magic power.
Crimson Fire.
Pitch-black Darkness.
Azure Water.
Dark Purple Poison.
Golden Lightning.
Dark Brown Iron.
Seeing Kenichi sweeping over from the sky, the Fire Dragon God's expression changed dramatically.
In his previous attack, the Fire Dragon God hadn't held back at all.
He was confident that even if another of the Five Dragon Gods, like the Water Dragon God, were hit, they would undoubtedly die.
But what he never expected was that Kenichi was still alive.
And completely unscathed.
'Why?'
'Why was this person unharmed?'
Before the Fire Dragon God could counterattack, Kenichi's figure had already closed in on his massive body.
"Dragon Slayer Secret Art, Six Dragons, Crimson Lotus Phoenix Blade!"
Viewed from the sky, Kenichi's figure, like a giant six-colored fire lotus, crashed thunderously into the Fire Dragon God's massive body.
Boom-
At that moment, a violent impact sound echoed between the sky and the ground.
Instantly, an impact wave, like ripples, spread out from where Kenichi and the Fire Dragon God collided.
Simultaneously, the Fire Dragon God's massive body, like a cannonball, crashed down into the crater created by his own roar.
Boom-
The moment the Fire Dragon God's body hit the ground, the entire earth trembled.
The steam that had been continuously rising from the crater seemed to be dispersed by the powerful air current.
"What's the situation?"
Because Erza, Mirajane, and the others were quite far from the battlefield, they only saw a black shadow fall into the crater on the ground… they couldn't see anything else.
A long time passed, and there was no movement from the battlefield.
But then, Kenichi's voice came through in Erza's mind.
"It's over!"
Hearing Kenichi's words, Erza was overjoyed.
Then, they operated the magic airship and flew towards Kenichi's location.
Meanwhile, Kenichi was collecting the various attributes dropped by the system during his fight with the Fire Dragon God.
As those attributes merged into his body, the various stats on Kenichi's screen surged significantly.
Since Kenichi's Magic Power had already reached a terrifying 150,000, an increase of three or four thousand now didn't feel like much.
However, what caught Kenichi's attention was that his Combat Power attribute surged from 760.1 to 883.1.
That was an increase of over 120 points at once.
"It seems fighting dragons really is the fastest way to increase Combat Power attributes!"
Kenichi clenched his fists, feeling the surge of power in his body, and was very pleased.
When Natsu and Gray fought, the system only dropped Combat Power attributes of zero point something each time.
Even collecting hundreds of such attributes would only increase Combat Power by a few dozen points.
But fighting dragons increased it by dozens or hundreds at a time.
Although 1000 instances of 0.1 is the same as 1 instance of 100, seeing the system drop 100 Combat Power points at once just feels more satisfying.
Besides the Combat Power and Magic Power attributes, the system also dropped Ignia's Fire Dragon God's Power attribute.
Looking at the Fire Dragon God's Power attribute and the Fire Dragon Slayer Magic attribute on the system screen, Kenichi was a bit puzzled.
After all, the power he could unleash with these two forces seemed the same.
However, since the system dropped this attribute, he naturally wouldn't refuse it.
"Kenichi-nii!"
Just as Kenichi was collecting attributes, Erza, Wendy, and the others approached.
Soon, Erza and the other two saw the Fire Dragon God lying in the crater, missing one dragon claw.
"Tch, I never thought I'd be defeated by a human other than Acnologia."
Under everyone's gaze, the Fire Dragon God said somewhat self-mockingly.
"Other than Acnologia? Does that mean Acnologia is human?"
Hearing the Fire Dragon God's words, Erza's brows furrowed.
But the Fire Dragon God didn't answer Erza's question.
He just looked at Kenichi and said, "You were sent by that old fool Elefseria to deal with the Five Dragon Gods, right? As a reward for defeating me, I'll tell you Viernes's whereabouts!"
'Viernes!'
Hearing this name, Kenichi's mind stirred.
This was undoubtedly the name of the mysterious Gold Dragon God.
…
After learning the Gold Dragon God's location from the Fire Dragon God, Kenichi, Erza, and the others left directly.
"Kenichi-nii, are we going to find the Gold Dragon God?"
"Let's rest for now. We still have plenty of time anyway."
In Kenichi's view, he just needed to complete this 100-Year Quest before Tenrou Island is unsealed.
Besides, he could use this time to research magic properly.
For example, the ability of Arc of Time to develop a Second Origin.
Or, for instance, whether Marin's Spatial Magic and Midnight's Reflector Magic could be developed into something like Obito's Kamui.
