Looking at the faint fire up above, Di Tou hesitated for a moment before taking a few steps, shooting up in the air and allowing him to view the flame from an even height. Inside of the strange looking sconce, there was a very soft, vaguely green flame burning in a pool of what looked to be black oil. Staring at this flame for a while, Di Tou hesitated before taking a deep breath. Dropping back down to the ground, Di Tou once again created a circle of wind around himself, forcing out all the air in his vicinity. At this moment, Di Tou was in a somewhat vacuum, with nothing to breathe at all.
After doing so, Di Tou stretched out a palm and shot out a small spark that appeared outside of his wind bubble.
Watching the spark float in the air, Di Tou waited for nearly three minutes, controlling the spark to float around all over the room before releasing the air bubble and bringing the spark back to his side to act as a light source.
