"Another world?"
Sade's worldview was still limited to this world, and he could not quite understand what Austin was talking about.
Austin smiled and looked up at the "son" he had raised with his own hands.
"No matter how big you get, you're still just a brat~"
Even though Sade's Haki had grown alongside his spirit, swelling to the limits of surpassing a king and beginning to approach Austin's own level, Austin still saw him as a brat.
Part of the reason was Austin's own Haki. Over the years, after experiencing the Rocks incident, meeting and fighting Joy Boy, toying with Imu... he had drawn ever closer to that limit.
His spirit had already begun to slowly approach a range that could envelop the entire world—the level of Joy Boy.
Yet he always felt that something was still missing...
Perhaps only after completing Sade's confrontation with Imu and manipulating the Great War that would shroud the entire world in the palm of his hand could he undergo his final transformation.
"Just from the existence of Devil Fruits, it isn't hard to see that time and space are powers that can be controlled. The existence of another world isn't that strange, is it?"
"Oh!!??"
"Would there be another me in that world too?!!"
Austin was taken aback by the question, then rubbed his chin.
"Well... I haven't looked too closely myself."
"Then let's take a look~"
A scarlet glow appeared in his eyes. With Observation Haki's power to transcend time combined with Austin's own Power of Space, his gaze twisted time and space as it turned toward that distant timeline...
