A Familiar Baleful Energy

Lin Mu and the others saw the grey wisps, as a few thoughts came to their mind.

"So it did come from—" But before Lin Mu could finish his words, another tiny grey wisp came out from none other than the Tracking tool!

"Huh?" Daoist Chu was surprised by this too but found the cube to have stopped moving. "Wait… is that why it was malfunctioning?" he wondered.

The tiny grey wisp joined up with the rest of the grey wisp and coalesced into a fist sized ball of energy. 

Xiao Yin didn't consume it since Lin Mu and the others needed to know what it was.

"How peculiar…" Crown Prince Feng Shun got closer to observe it and used his Immortal sense on the energy.

~SCREECH~

Doing that was not the best decision though as the Grey energy ball seemingly reacted by lashing back.

A screeching sound was heard as a worm like tentacle bit at the Immoral Sense tendril of Crown Prince Feng Shun.
