Opportunity or Disaster?

One month passed since the black mist started to gather around Ace, and the small mountain was now completely enshrouded in that mist! 

At this moment, black lightning suddenly shimmered over Ace's body and spread in the black mist. However, it didn't vanish as it continuously circulated within the black mist. 

Thereby, in front of Ace's chest, the dark lightning-filled mist started to gather into a tiny ball without stopping. 

All that mist accumulated within this sixth month was now gathering in front of Ace, condensing a pitch-black mist ball as its size slowly grew. 

Soon, all the black mist was condensed into a three inches ball, which looked black then black as it hovered in front of Ace. 

At this moment, Ace's eyelids snapped open as they shone with despair lightning as he looked at the small black ball emotionlessly.
