Rio Vs. Seven, A Duel between Master Swordmen... Part-1.

'Where did this peak S ranker even come from? Even my mana detection didn't see it coming…'

Despite him being at A rank, Rio's mana detection skill is nearly as powerful as a peak S ranker, so it shouldn't be that easy to completely ignore the detection range of his skills.

Yet that person in the dark black armor walked over in front of him slowly, and Rio only noticed the other party when the other party had already appeared in front of his eyes.

'There was no mention of Alverto in the original novel, and now another completely unknown S ranker has appeared in front of me again…'

While Rio was still thinking about who the other party was, the figure of the other party moved and disappeared among the falling debris.

'What the!? I lost track of him again!?'

Seeing that the other party was able to erase his presence to this extent and fight in stealth mode, Rio immediately activated his shadow robe and covered himself with it from head to toe.
