Nandu Underground Containment Area
"The Curse Key is classified as a C-level dangerous Extraordinary Item according to the Research Institute's ranking system,"
Ye Yun led He Ao forward, quickly passing through the corridor, and softly introduced, "It's kept in the deepest level of the Nandu Research Institute's Underground Containment Area."
"This C-level classification, is it based on the highest level of harm it can inflict on Transcendents?"
He Ao glanced at the special compartments marked with label numbers beside them, each compartment had a monitor displaying the status of items inside.
They seemed to have already entered the 'D Area' of this containment zone, and all the item numbers began with D.
