—— Activating 'Clairvoyant Vision' requires about one-third of a second, and the physical strength consumed is roughly equivalent to 'throwing a full-force punch'.
Even Ian, who has improved his physical strength now, cannot open and close it more than twenty times in a row.
It's not that he lacks the physical strength, but his mind cannot withstand the pressure brought about by activating Foresight View.
Just like ordinary people, don't they have the strength to throw twenty punches in a row? They simply have not mastered the method; if they exert force incorrectly, naturally their elbows and arms will feel sore and uncomfortable after repeatedly throwing punches.
Ian believes that he can gradually enhance the speed and endurance of activating Foresight View through a lot of practice, mastering a more scientific and reasonable method of activation.
Maintaining Foresight View also requires the consumption of physical strength.
