Returning from the Dragon Ball World, Adam entered the Fairy Tail World.
However, he didn't continue to seek Makarov for research into the Black Magic; instead, he flew towards the Alvarez Empire on the Western Continent, intending to find the Dark Mage Zeref Dragneel.
The magic of the Fairy Tail World, thanks to the Second Guild Master's memories and his own research during this period, had already laid a solid foundation.
If he were to explore it slowly on his own, it would be too time-consuming, especially since he could only enter this World for one hour each day.
It would be better to directly find the two people in this World with the deepest research into magic. As long as he acquired their memories and knowledge, he wouldn't need to bother coming over every day; it would be enough for him to study for a very long time.
These two individuals were none other than the Dark Mage Zeref and Mavis, the creator of Fairy Tail's three Great Fairy magic spells.
The Dark Mage Zeref was acting as emperor on the Western Continent, while Mavis's soul had returned to the Fairy Tail Guild after the Tenrou Island incident, with her body remaining in the Guild's Basement.
He hadn't done this before, partly because his foundation was unstable, and partly out of fear of Ankhseram God, who controlled life and death in this World.
But now, with his strength and having obtained the ophiuchus gold cloth, he could even exchange blows with Hades, King of the Underworld, in the Saint Seiya World. The God of life and death in this World was not someone he couldn't challenge.
If he truly couldn't defeat him, he could simply take Zeref and Mavis and leave this World.
Because of his immense speed, in the blink of an eye, he had already arrived above the Western Continent and saw the prosperous Alvarez magic Empire.
"That should be the royal palace!"
After circling above the Empire, he quickly located the royal palace, where the magic concentration was highest.
Holding his serpent staff and clad in the gleaming ophiuchus gold cloth, Adam arrived above the royal palace and shouted loudly using an amplification spell:
"Is Zeref here? Please come out, I have something to discuss with you."
His shout immediately caused an uproar throughout the entire royal palace. Countless magic soldiers surged out from various palaces, surrounding Adam.
A young man with a disc composed of twelve swords on his back emerged from among the soldiers and angrily roared at Adam in the air:
"Who dares to linger above the royal palace and call His Majesty by name!"
With that, he directly opened his mouth, took a deep breath, and unleashed Wind Dragon Slayer Magic at Adam.
"Storm Dragon's Whistling Wind and Moon!"
Immediately, a powerful tornado swept towards Adam.
However, facing this Wind Dragon Slayer Magic, Adam didn't even bother to block it, because an attack of this level simply couldn't breach the inherent defense of the ophiuchus gold cloth.
"So, it's Serena, the strongest of the Ishgar Four."
Looking at the appearance of the Mage below, Adam recognized his identity at a glance.
On the Ishgar Continent, where the Fairy Tail Guild was located, the currently recognized strongest Mage was Serena.
His body had absorbed eight Dragon Slayer Crystals of different attributes, allowing him to use eight types of Dragon Slayer Magic and even combine them. His strength was such that the three Saint Mages ranked after him combined were no match for him alone.
He had joined the Alvarez Empire because he wanted to defeat the Black Dragon, but he was instantly killed by the Black Dragon in a single blow.
"I have no ill will. Is Zeref here? I need to find him for something."
After the storm passed, Adam descended from the air completely unharmed and asked Serena.
Serena, seeing that Adam had actually blocked his Dragon Slayer Magic, immediately showed an excited expression in his eyes.
"Interesting. Besides His Majesty, no one has ever taken my Dragon Slayer Magic without a scratch. Then let's try this one."
He let out a roar:
"Eight Dragon's Scattered Flowers!"
Eight types of Dragon Slayer Magic were unleashed simultaneously, transforming into eight giant dragons of different colors that assailed Adam.
Adam raised an eyebrow:
"Eight? I'll send you a thousand."
As he spoke, he had already read the answer he wanted from Serena's brain, so he returned with a special move he had just learned from Dohko.
"Rozan - Hyakuryuha!"
Rozan Hyakuryuha was just the name of the technique; the actual number of dragons released depended on one's strength. Having just learned it from Dohko, he could unleash a thousand.
Serena's eight magical energy dragons met Adam's thousand Blue Dragons and shattered with a roar.
"How can this be?"
With a cry of alarm, he was struck by a thousand Blue Dragons and immediately passed out.
Mainly, Adam had held back; otherwise, if he had been hit with full force, he would have probably been reduced to ashes.
"Serena was defeated in a single move!"
At this moment, the other "Spriggan 12" also arrived and, seeing that Serena, who was ranked third in strength among them, was defeated in a single move, they all showed expressions of shock.
"This guy, he's not in the Empire after all."
After effortlessly defeating Serena, Adam couldn't help but murmur.
He had read from Serena's memories that Zeref was not in the Empire at this time but had gone on another journey.
As for where he went, no one in the Empire knew.
"You two aren't bad either."
He looked up and saw the magic King August and Irene Belserion, the Scarlet Despair.
August was the son of Zeref and Mavis, abandoned by the Second Guild Master back then. Because of his Copy magic, he was proficient in all magic, ancient and modern, Eastern and Western, and was known as the magic King.
He was the strongest Mage in the Alvarez Empire besides Zeref, and also the de facto administrator of the Empire.
Zeref was a hands-off manager, often traveling and not really managing the Empire.
Irene Belserion, the mother of Fairy Tail's Queen Erza, and also the founder of Enchantment magic and Dragon Slayer Magic, had lived for over four hundred years.
If he could extract the magic-related memories of these two, he would gain a lot of magical knowledge.
While Adam was contemplating this, everyone around him had already unleashed their magic attacks on him, the intruder.
"Lightspeed Fist!"
Adam extended a finger and pointed forward. All their magic instantly shattered, and at the same time, each person received a solid punch and then fainted.
Just kidding, with Lightspeed Fist delivering a hundred million punches per second, if he wanted to, the people present wouldn't even have a chance to cast their magic.
Taking an Owl out of the Primordial Space, he handed an envelope addressed to Zeref to the Owl. Adam, holding August in one hand and Irene in the other, followed the Owl in the direction Zeref was located.
During the flight, he wasn't idle. First, he read all of the magic King's memories regarding magic, and then he read all of Irene's memories regarding magic.
Reading memories didn't mean he had learned them; it was more like memorizing the relevant magical knowledge. To fully master it would still require time for slow research.
"Enchantment, Speed!"
He tried using the Enchantment magic from Irene's memories to speed up the Owl. The Owl, which originally flew at about eighty kilometers per hour, directly broke the sound barrier, astonishing the Owl itself.
So, very quickly, he found Zeref lying on a mountaintop, sunbathing on a deserted island.
