[Ultimate skill: Soul Splitting!]
Rio swung his sword horizontally at an insane speed.
Rahab was not a genuine SS-ranker originally, in fact, he didn't even have the 'authority' to walk in the air like an S-ranker could. In his mana-less state, he was currently weaker than a genuine S-ranker.
Nonetheless, his physical stats were still at the level of an SS-ranker though.
His perception was on par with a genuine SS-ranker and thus he immediately sensed it.
Death.
He sensed his death from Rio's attack, that sensation immediately caused him to become sober and the fear of death made his chaotic mind, calm down instantly.
He stomped on the ground with all his might, broke through the ceiling, and jumped out of this underground hall at an insanely fast speed.
Rio's attack missed.
