"It's the Astral Ephemera."
The mage standing next to Louis frowned and said:
"Is the other end of this space rift the astral plane?"
William shook his head and said:
"Probably not just that. I can sense that the Ether plane is almost in direct contact with the crystal wall of the main material world here."
Louis pondered for a moment and said:
"It's not just the Ether plane; I also sense the breath of the Shadow plane."
Perhaps because Louis had previously, through Lime, devoured a large number of monsters from the Fallen Shadow Nether Realm, his ability to sense the Shadow plane was stronger.
The Shadow Hand style among the Nine Sword practitioners uses the power of the Shadow plane.
Among the four level one martial techniques of Light and Shadow Hand style, three are linked to the Shadow plane—
Technique Stance·Shadow's Child; Strike Technique·Shadow Strike; Strike Technique·Shadow Blade.
The other levels are similar.
