Zaria exhaled softly, her lips curving into a smirk, "Grade Six. That's child's play!"
The next moment, the wall in front of them shimmered faintly, and then it shifted. The solid stone dissolved into mist, revealing a descending stairway that led into darkness, and a cool, abyssal wind drifted upward from below, carrying a faint metallic scent.
Ace's eyes gleamed with approval, "Nicely done. Below this path should be the inner vault chambers. If I remember correctly, the treasury must be protected by a Quasi-Grade-8 formation!"
Zaria arched an eyebrow as she didn't like Ace's words and scoffed, "That's supposed to impress me?"
Ace chuckled quietly, "No, but it should make you cautious. Khazar might not have stationed guards here, but that's what makes it even more dangerous!"
Zaria didn't reply, and followed by Ace, they started to descend.
