Master Yue praised Feng Jun with a sentence, without any targeted words, seemingly a casual compliment.
Then, he took out an object and placed it on the table, "Here's the item, could you please divine it, Feng Xiaoyou?"
The item was placed in a transparent box, with a seal over it. It looked like a fragment of a shell, palm-sized and colored dark green, a piece of a circular shell split open, with a few protruding spikes on the surface.
Feng Jun blinked and pointed at the transparent box, asking in a deep voice, "A seal to block perception?"
"No," Master Yue shook his head, "It doesn't block perception, just prevents the remaining aura from leaking out."
Feng Jun took out a cigarette and lit it, swiping casually on his mobile phone, "What aura? What type?"
"Related aura, I am not very sure," Master Yue answered vaguely, "No obvious characteristics."
Feng Jun nodded, took another puff of smoke, and asked slowly, "Sealed for a long time?"
