Bai Ning Bing couldn't help but become curious when she saw Fang Yuan walking towards the dark leopard's corpses.
She saw him squatting down and feeling around the ears of the dark leopards.
After a while, Fang Yuan took out two exquisite purple leaves from the male leopard's left ear and the female leopard's right ear.
This was Breath Concealment Gu.
Rank three grass Gu; Gu Masters could use it to conceal their aura and cultivation level. To some degree, it was a camouflage ability.
Almost all the dark leopards had a Breath Concealment Gu in the ears. However, the dark leopards moved in pairs and were at least of thousand beasts king level. They were experts in sneak attacks, and were extremely agile; capturing them was a very troublesome and dangerous endeavor.
Moreover, the dark leopards were specific to Zi You mountain. Thus, the knowledge of there being Breath Concealment Gu in dark leopard's ears wasn't widely known yet.
