Blinding Shadow Stream Nightingale

Lin Mu watched in surprise as an area of ten meters was swallowed up by pitch black darkness. It was very similar to the darkness he had felt in the Sea of Death Qi, but this darkness felt like the absolute darkness of the void itself.

Touching it lightly, Lin Mu could feel nothing there.

'It has no mass… or anything perceptible in it. It's just empty.' Lin Mu analyzed. 'It's as if I'm touching a shadow; it feels like nothing but my finger dispersals inside it.' He noted.

Lin Mu put more of his hand inside and saw the entirety of it disappear within it. 

"It hides things visually, but they can still be perceived physically." Lin Mu said after testing it with his Immortal Sense. 

"Indeed." Xukong replied. "But this is more than just that." He added.

"How so?" Lin Mu inquired.

"Try making some fire." Xukong requested. 

"Alright." Lin Mu quickly ignited a flame on his finger.
