Atop the stone platform, aside from the crystal sealing the Nine Nether Soul-Devouring Flame, there was also an arm-length shuttle spinning through the air.
However, three bright silver threads connected the shuttle to the crystal on the stone platform.
No matter how the shuttle struggled, it was bound by those three bright silver threads and could not leave the stone platform's range.
Gu Yi glanced at the shuttle and recognized its origin.
This shuttle was called the Flowing Cloud Sky-Rending Shuttle. It was a fifth-tier treasure capable of tearing through space and breaking any barrier below the sixth tier.
It was indeed extraordinary, worth even more than many sixth-tier treasures.
However, it held little appeal for Gu Yi, who possessed numerous precious treasures.
Gu Yi was more concerned with the Nine Nether Soul-Devouring Flame.
The moment Gu Yi entered the cave, the sealed Nine Nether Soul-Devouring Flame sensed his presence.
"Human, leave at once!"
The bright silver flames within the crystal suddenly condensed into a slightly blurred human face.
The Nine Nether Soul-Devouring Flame had existed for countless years. It had seen innumerable powerful experts and possessed extraordinary knowledge.
At a glance, it could tell that Gu Yi was immensely powerful and not someone to provoke.
Its seal had become extremely damaged after ten thousand years, and it would not be long before it broke free.
Naturally, the Nine Nether Soul-Devouring Flame did not want to be targeted by an expert like Gu Yi at such a critical moment, only to be sealed away for countless more years.
Thus, the first thing it did was threaten Gu Yi into leaving.
As for being devoured and refined by someone?
The Nine Nether Soul-Devouring Flame had never worried about that.
Since its birth, no living being had ever truly refined it.
Anyone
