The moment Kenichi, holding Zeref's head, charged into the rift of the Space Between Time, their figures completely vanished from this world.
In the next second, when Kenichi reappeared, he was already in another world.
Looking around, Ethernano Crystals were everywhere.
Those Ethernano Crystals resembled mountains, islands... as if the entire world was composed of them.
"So this is the world within the Space Between Time?" Kenichi stood on a massive Ethernano Crystal island, scanned his surroundings, then murmured in a voice only he could hear.
After speaking, he lowered his head and looked at the Ethernano Crystal beneath him.
Kenichi could sense that the Ethernano Crystal was filled with immensely powerful magical power.
And this magical power was precisely the space-time magical power he desired.
'As long as I devour the magical power of this entire world, I can master the power of space-time!'
'Then, let's begin!' Thinking this, an immensely powerful surge of magical energy erupted from around Kenichi.
Zeref, who had fallen onto another Ethernano Crystal island, sensed this sudden burst of powerful magical energy and sharply turned to look in Kenichi's direction.
"That is..." Soon, under Zeref's watchful gaze, Kenichi's figure, within a multicolored pillar of magical light, began to enlarge at a visible rate.
Soon, Kenichi transformed into a Golden Dragon even more massive than the Ethernano Crystal islands.
"A dragon?!" Seeing the Golden Dragon radiating a sacred golden light, Zeref was momentarily dazed.
At this moment, he understood why Kenichi possessed the strength to kill Acnologia.
"I see... So this is your true form? A Dragon Slayer!" Zeref looked at the immensely majestic Golden Dragon and curled his lips into a smile.
Then, under Zeref's gaze, Kenichi, transformed into the Golden Dragon, vigorously flapped the golden wings on his back, and his colossal body flew high into the sky.
The Golden Dragon opened its enormous maw, and the gaseous magical power permeating the surrounding space converged frantically towards the Golden Dragon's location like a tidal wave.
At that moment, the entire space of the Space Between Time was filled with turbulent air currents.
"He actually intends to devour this world of the Space Between Time?!" Zeref, caught in the turbulent air currents, watched the Golden Dragon continuously devour the magical power of the entire world, his face filled with terror.
Whoosh- Whoosh- Whoosh-
As the gales howled, vast amounts of space-time magical power continuously poured into Kenichi's body.
And the vast magical power within Kenichi's body grew incessantly.
Soon, the massive Ethernano Crystal beneath Kenichi began to crumble under the powerful air currents.
Countless Ethernano Crystal's fragments, along with the air currents, converged towards Kenichi's body.
A few minutes later, the Ethernano Crystal island where Zeref stood also began to collapse.
Losing his footing, Zeref's body was enveloped in a layer of purple magical energy, and his figure levitated into the high sky.
Time passed second by second.
The immense magical power of the entire Space Between Time world continuously converged into the Golden Dragon's body.
And the golden light radiating from the Golden Dragon grew increasingly dazzling.
No one knew how much time had passed.
The Golden Dragon finally devoured all the Ethernano Crystals in the entire Space Between Time World.
At this moment, the Space Between Time World became a void world.
And the Golden Dragon, levitating high in the sky and radiating dazzling golden light, was like a golden sun.
Zeref, who witnessed the entire devouring process, looked at the Golden Dragon in the sky with shock.
He took a deep breath and, after a long time, slowly said, "He really devoured this entire world."
While Zeref was speaking, Kenichi also carefully felt the surging power filling his body.
'So this is the power of Space-Time?'
'Now, I should possess the power to manipulate time and space, right?' Kenichi, in his Golden Dragon form, clenched his massive golden dragon claw and thought to himself with satisfaction.
Just as Kenichi prepared to test this newly acquired power, the void world of the Space Between Time suddenly began to tremble.
'Hmm?' Kenichi withdrew his thoughts and looked towards the surrounding void space.
After devouring all the magical power of the Space Between Time, Kenichi discovered he had formed a certain mental connection with the entire Space Between Time World.
This connection allowed Kenichi to control everything in this world.
Through this connection, Kenichi also knew that the tremor that just shook the entire world was caused by the instability of the vast Space-Time magical power within his body.
Kenichi wasn't too surprised.
After all, in the original work, after Acnologia devoured the vast magical power of the entire Space Between Time, he also experienced power instability.
To stabilize this power, a vessel was needed for harmonization.
Thinking of this, Kenichi turned his gaze to Zeref.
"Zeref, it's your turn now!" With that, Kenichi's massive dragon claw made a grasping motion towards Zeref's body through the air.
"My body can't move?!"
"This is spatial binding... I see. You have completely mastered this world." Zeref, his body bound by space, looked at the distant Golden Dragon and said with gravity.
After restraining Zeref, Kenichi activated his Enchantment Magic, attaching the Jade Dragon Force to Zeref.
At that moment, Zeref became the Jade Dragon Slayer.
"This is... Dragon Force? What exactly are you trying to do?" Zeref, sensing that Kenichi had attached Dragon Force to him, felt even more puzzled.
But no one answered Zeref's doubt.
After Zeref became a Dragon Slayer, a massive Ethernano Crystal appeared beneath him.
The Ethernano Crystal, as if alive, grew upward at a visible rate.
Soon, Zeref's entire body was covered by the growing Ethernano Crystal.
After a few seconds, a giant Ethernano Crystal pillar appeared in this void world.
And Zeref was precisely at the center of that Ethernano Crystal pillar, transformed into the vessel.
Not long after this vessel appeared, the constantly trembling world calmed down once more.
"The power has been harmonized!"
"I can now completely master this space-time power!" Feeling the power within his body tending towards calm, Kenichi felt a surge of joy.
"I wonder how much time has passed in the outside world. It's about time to go back!"
