Primordial Natural Weapon

Cain's disappointment vanished the instant he heard the news of a mysterious weapon. A weapon once used by a Peak Prima Deity on the verge of the ArchDeity Rank had to be immensely powerful—enough, perhaps, to tip the balance of his current predicament. Yet, in the next breath, confusion colored his features.

"I examined your corpse thoroughly," Cain remarked, his gaze turning skeptical. "But I never found any spatial storage item on it. I'm sure I would have noticed if it was there."

The Sky Sovereign's phantom form only gave a small, knowing smile and slowly shook his head.

"My storage dimension isn't actually on my body, but in," he replied, leaving the rest of his explanation cryptic.
