Even though successfully guiding Ennis Hawkins towards awakening should be an amazingly happy event, at this very moment, the mysterious man was experiencing a blend of pain and pleasure.
The pleasure undoubtedly came from Ennis's side. After planning it for so long, he finally helped Ennis break the shackles of the past 20 years.
More than that, making Ennis recall the sealed quest that was already completed, helped him achieve the fourth-turn in one go. Thus, the mysterious man also fulfilled his long-standing wish.
But the pain mostly came from Dean McKenzie's situation.
Time rewinded back a few minutes ago, particularly, the several seconds when the "Demon Box" shattered.
Those seconds were a near-death experience for the mysterious man.
If his reaction had been a little slower, he probably wouldn't have achieved the effect he has now.
Because what happened in the "Demon Box" again exceeded his expectations.
