Entering the Underworld Castle, Felix rejected the maid's help and made his way to the forbidden library, which was located on the same large corridor as the 'training hall'.
Felix stood before a dark red double door, which was designed so intricately that any person would freeze and continue to stare at it for long hours.
The same happened to Felix, but he blinked his eyes as the passive skill Equanimity came into effect.
"Ugh....that's some troublesome door."
He muttered and quickly pushed the door open, stepping in as he felt a kind of silence and serenity that almost stopped his process of thought.
'What's wrong with this place? Everything seems so.....strange?'
But that thought didn't last long as Felix looked forward and became stunned when he witnessed the interior of the forbidden library.
'What the hell happened here!!??'
