Zuo Jing's SSS-level Invisibility Breaking Stone was recognized as the treasure with the highest priority for breaking invisibility below the Above SSS-level.
If this can't break it, then the opponent simply can't be in invisible mode, Rangu thought. But why can't we detect him?
He racked his brains but couldn't understand the reason.
"My Lord, what should we do now? Is the target still there?"
Receiving his subordinate's reply, Rangu glanced at the report again; the target hadn't moved at all.
He suddenly thought of a possibility and said, "Could they have burrowed into the ground? Investigate the ground conditions."
The three immediately landed and found only a pile of ashes from something unknown that had been burned. As for anything else, there were no signs of digging on the ground.
"My Lord, there are no signs of any disturbance on the ground. Could it be a subterranean ability? We might find it difficult to continue the search. We need someone skilled in burrowing."
