When Hades left Fairy Tail, he was still a kind elder solely dedicated to the study of magic. It was precisely because he recognized Makarov's determination to protect his companions and promote the guild that he passed on the position of Guild Master to Makarov.
However, Hades later fell into darkness due to his obsession with Zeref's Black Magic. Using the fairy heart as a prototype, he developed a Grimoire Heart, crafted by combining countless lives with Black Magic.
As long as this heart existed, he would be Sage and possess an inexhaustible supply of magic power.
"Explode!"
While continuing to absorb Hades' soul, Adam raised his hand, aimed at the Grimoire Heart, and fired a ki blast directly at it, instantly shattering the Grimoire Heart into pieces.
Sure enough, as soon as the Grimoire Heart vanished, Hades' soul was instantly drawn out of his body by Adam.
He then began to read and copy all knowledge related to magic.
Having lived for over a hundred years, meticulously studying various magic, perhaps in terms of magical strength and talent, Hades might not be considered top-tier in this World.
But if it was only about theoretical knowledge of magic, about the collection of magic, Hades would definitely rank high.
In addition to normal Molding magic, Take Over magic, Re-equip magic, Stellar Spirit magic, Letter magic, Picture magic, various Elemental magic, and so on.
There were also the lost Arc of Time, Arc of Embodiment, Arc of Great Tree, Gravity magic, as well as various Forbidden magic and God Slayer magic.
Finally, Hades had also learned many of the various Black Magic invented by Zeref.
Although he couldn't master all of them, that knowledge was stored in his mind, and he had specifically trained experts like the Seven Kin of Purgatory.
Adam reading Hades' memories was equivalent to having read a vast library of magic in this World.
Once fully digested later, it would significantly improve his magical prowess.
"Phew, this trip was worth it!"
Opening his eyes again, Adam nodded in satisfaction.
"Apparition."
Teleporting back in front of Makarov and the others, Adam threw Hades' corpse onto the ground.
"It's over so quickly!"
Looking at Hades' corpse, Makarov's eyes once again showed an expression of disbelief.
From Adam flying away, to casually dealing with the Grimoire Heart vice-master mid-flight, then entering the Grimoire Heart's magical airship to deal with Hades, and teleporting back—the entire process took less than three minutes.
They hadn't even had time to figure out how to get onto the magical airship to help.
However, Makarov's feelings about Hades' death were still very complex.
After all, before he turned dark, Hades was indeed a very good Guild Master, and he had shown him great care and trust, making him a highly respected elder.
"It's not over yet. He was just an appetizer; the truly formidable ones are yet to come."
Adam smiled at the words.
Hades' strength was definitely above that of an average Great Mage, but when facing Zeref, he was instantly killed with one move.
However, even a powerful Dark Mage ancestor like Zeref admitted he was no match for the Black Dragon of Apocalypse.
So, compared to the Black Dragon of Apocalypse, Hades was indeed just an appetizer.
"What do you mean?"
Hearing Adam's words, everyone's hearts instantly sank.
Such a powerful existence as Hades was not the final enemy, but merely an appetizer? How terrifying would the final enemy be?
"Everyone, are you alright!"
Just as Adam was about to explain, a shout suddenly came from a distance.
It turned out to be Erza, the Queen of the Goblins, Gildarts, Fairy Tail's strongest Mage, Gray, Juvia, Gajeel, Cana, Levy, and other Fairy Tail Mages, who had rushed over after hearing the commotion.
"What, Natsu defeated five of the Seven Kin of Purgatory by himself, and also defeated the Guild Master and Vice-Master of Grimoire Heart?"
After the two sides met and exchanged information, Erza and the others looked at Natsu, controlled by Adam, with incredulous eyes.
They knew that it had taken them considerable effort to defeat the remaining two of the Seven Kin of Purgatory and some other executives.
"Natsu's situation is special; I'll explain it later."
Seeing Erza and the others wanting to get to the bottom of it, Makarov quickly interrupted, then asked Adam again:
"Who is the final enemy you spoke of?"
"Boom!"
However, just as Adam was about to explain again, a sudden yellow lightning bolt descended from the sky. Laxus, the Lightning Dragon Slayer Mage, grandson of the Third Guild Master, and S-Rank Mage, made a dazzling appearance.
"Old man, are you alright?"
It was Laxus, who had already been expelled from the guild, but upon hearing about the incident on Tenrou Island, he rushed over immediately.
"Laxus!"
Seeing Laxus appear, everyone was excited, especially the three members of the Thunder God Tribe.
However, Makarov immediately stopped everyone's greetings after their reunion and turned to look at Adam.
"Hmm, it probably won't appear now."
After being interrupted twice, Adam changed his tone and altered his answer.
Because in that short time, he suddenly thought of a problem.
That was, the Black Dragon Acnologia's original attack on Tenrou Island was because Tenrou Island was not far from its dormant place, and it was awakened by the aura of the Dragon Slayer Mages during the battle between Fairy Tail and Grimoire Heart.
Mainly, Natsu's attack in Lightning Flame Dragon Mode was too conspicuous.
Acnologia's goal had always been to kill dragons, to kill all dragons and Dragon Slayer Mages who could potentially turn into dragons.
Four hundred years ago, he believed he had eliminated all dragons, which is why he disappeared from the World.
So this time, his attack on Tenrou Island was mainly to eliminate Fairy Tail's four Dragon Slayer Mages.
However, because of Adam's appearance, Natsu did not use Lightning Flame Dragon Mode at all, and thus would naturally not awaken the sleeping Black Dragon.
Having figured this out, he suddenly changed his answer.
"Since the matter is resolved, I'll take my leave. See you next time.
Oh, and my name is Adam!"
With the matter settled, Adam did not linger but ended the Dream Walking Technique.
Hades' magical knowledge would be enough for him to digest for quite some time, so he wasn't in a hurry to acquire new magic recently.
His consciousness returned to his main body, and the battleship had just landed on the super-large plaza of the capital's royal palace on Zela Star.
At this time, the plaza was filled with welcoming parties for the return of the ancestor, Silver Surfer. Adam did not participate, but instead had the female officer Cereta lead the way to the VIP room in the palace to rest first.
"Resting," in fact, meant entering the Primordial Space and training in the Gravity Chamber.
When he left Earth, he had already moved the Gravity Chamber into the Primordial Space. If he wished, he could activate his Nine Tomoe Rinne Sharingan at any time and enter to Training.
He wanted to be able to contend with the Celestials in three years, which would require at least transforming into Super Saiyan One.
And the most basic condition for becoming Super Saiyan One was to reach a base combat power of three million in his normal state. He was currently just over three hundred thousand, still a long way off.
