Hades's Demon's Eye could not only suppress magical power but also had detection abilities.
In the original story, he clearly saw the battle between Ultear and Zeref.
Naturally, he also witnessed the battles between Kenichi and the Seven Kin of Purgatory.
"Bluenote, leave this mage to me!"
Hades looked at Kenichi standing in the air and said in a flat tone.
Hearing Hades's words, Bluenote's mind stirred.
"Quite rare for you to take action personally!"
As he spoke, Bluenote's gaze shifted from Hades back to Kenichi.
From their brief exchange, Bluenote already knew Kenichi was no ordinary mage, so he could understand Hades's decision.
But since he hadn't yet settled the score with Kenichi, Hades intervening now left Bluenote somewhat dissatisfied.
However, seeing the expression on Hades's face, Bluenote didn't object:
"I understand. I'll leave this one to you. I'll handle the rest."
"Suit yourself."
The deck of the magic airship was several meters high, and Hades stood in the center of the deck.
Erza, Mirajane, and the others below the magic airship could only hear Hades's voice but couldn't see him.
"Who's speaking?"
Carla beside Wendy looked at the magic airship and asked.
"Probably the Master of Grimoire Heart, right?"
Wendy said uncertainly.
While Carla and Wendy were talking, Erza said in a deep voice: "He's coming!"
As soon as Erza finished speaking, Bluenote, standing at the edge of the magic airship, jumped directly towards where Erza and the others were.
While falling, Bluenote applied super gravity to his own body.
Therefore, Erza, Mirajane, and the others felt an immense pressure.
They didn't hesitate and immediately scattered in all directions.
Soon, Bluenote's body crashed into the spot where Erza and the others had been standing.
Boom-
Accompanied by a loud roar, a violent shockwave mixed with rock debris spread out in all directions. Kenichi glanced down towards Erza, Mirajane, and the others below.
Noticing Kenichi's gaze, Erza gripped her sword: "Leave this place to us!"
"Although I don't like fighting, to protect everyone, I have no choice but to act!"
Mirajane stood straight, saying with determination.
Seeing this, Kenichi withdrew his gaze and turned back to Hades before him.
Although Bluenote was strong, Erza and Mirajane were not weak either.
Kenichi trusted them.
Moreover, Kenichi had applied a magic circle over there.
Within the magic circle, Bluenote's Gravity Magic would be greatly restricted.
"Brat, facing me and still concerned about others? You really don't take me seriously!"
"Has the literature in the Fairy Tail Guild already lost all records about me?"
Hades looked at Kenichi and said in a flat tone.
"I know you, Precht."
Kenichi flew onto the deck of the magic airship and said to Hades.
Precht.
When Kenichi uttered this name, Hades's old face changed slightly.
No one had called him by that name for many years.
Hearing it now, and from a young man no less, stirred something in Hades's heart.
"Did Makarov not teach you to respect..."
Before Hades could finish, Kenichi interrupted him.
"Enough with the extra talk. Let's fight!"
"What an arrogant brat! Today, I'll teach you a proper lesson on Makarov's behalf!"
With that, Hades brought two fingers together and swung them towards Kenichi.
"Dark Chain!"
Whoosh-
A black chain formed from condensed magical power swept directly towards Kenichi.
Just as the black chain was about to hit Kenichi, a figure appeared out of thin air and punched towards the black chain.
Boom-
Zap zap zap-
Accompanied by a loud roar, violent lightning swept across the entire deck.
And Hades's magic was shattered.
"You are..."
Hades looked at the golden-haired man before him, and his usually impassive old face finally showed a trace of disbelief.
The man now appearing before Hades was none other than Yuri Dreyar, Laxus's great-grandfather.
He was also one of the founding members who established the Fairy Tail guild with Mavis.
And also Hades's former companion.
Seeing a companion he hadn't seen for decades suddenly appear before him, even Hades was somewhat moved.
Of course, Hades could also tell that the Yuri before him was only manifested by Kenichi.
"Manifestation magic?"
"I didn't expect anyone besides Rustyrose to use this kind of magic!"
After calming his emotions, Hades said to Kenichi in a rather cold tone.
It seemed he strongly disliked Kenichi manifesting Yuri.
"Quite unexpected. I didn't think you'd still care about your former companions."
Kenichi mocked, then said to Yuri: "Attack!"
With Kenichi's command, Yuri immediately launched an attack against Hades.
"Don't play these boring games with me!"
Hades seemed eager to eliminate Yuri, using a major killing move right from the start.
"Amaterasu Formula 100!"
Hades assumed a stance with his hands, and the next second, circles of magic arrays appeared around Yuri.
After seven magic circles appeared out of thin air, they emitted an exceptionally dazzling light.
Boooooom-
Soon, a terrifyingly loud explosion came from the magic airship.
"Kenichi!"
Below the airship, Erza and Mirajane, who were fighting Bluenote, heard the terrifying explosion. Their pretty faces changed, and they looked up towards the airship.
Seeing the pillar of fire shooting into the sky, they couldn't help but worry.
"Happy!"
"Aye!"
Although Erza didn't say much, Happy knew she wanted him to check the situation on the airship.
Happy responded, then flew directly up into the sky.
Meanwhile, Gildarts also heard the loud roar.
"This way?"
He didn't hesitate and headed directly towards the direction of the explosion.
