With Leo's current strength, even if he used all his trump cards, it would be nearly impossible to kill a normal peak Mythical Grade Beast and now, the [Heaven's Voice] wants him to kill an ascended beast.
Moreover, it was not a low-level ascender beast; instead, it was a Gold Grade Ascender beast.
Leo had to use almost all his trump cards to kill the Silver Grade Ascender beast.
Therefore, when he learned about the strength of the Fire Elemental Dragon King, Leo didn't hesitate to use the [Floor Clearance Card].
'Since I can't use the [Floor Clearance Card] after the 10th floor, I better use it now.'
[Floor Clearance Card]
'Kacha'
The [Floor Clearance Card] that Leo received from [Heaven's Voice] was the lowest card that could be used to skip a single floor from 1 to 10.
Therefore, Leo crushed it and used it directly to skip the trial and the floor.
