Along the way, Basil Jaak was still in shock from Ina's Dark Demon Method, and later he learned that the terrifying aspect of this method is that when it's unleashed, the world is instantly suppressed by darkness.
The duration of light suppression by darkness depends on the level of Dark Demon Method practiced, ranging from as short as one second to as long as five seconds.
During this descent of darkness, everyone's vision disappears, except for the caster, whose sight remains as clear as daylight.
Moreover, when the caster prepares to attack the target again, the target will be entangled by dark spirits, significantly reducing their combat ability in the darkness.
At this point, the caster's killing move is highly likely to succeed.
Because of this, after learning that Ina had mastered the Dark Demon Method, both Mack and Darren were visibly shaken.
In a situation where their strengths were evenly matched, Ina using this move to kill Darren was not particularly difficult.
