章節 404: Riya!? What are you doing!? Part-2.

'It's surprisingly empty; there aren't even any traps here... strange…'

After running through several dozens of corridors and hidden rooms, Rio still didn't encounter a single trap in the area, which was extremely strange.

'That so-called prototype had more traps instead... Is this really the genuine place?'

Not seeing literally anything for so long, Rio was having serious doubts about what's going on in this place.

'Why is it so empty?'

*AAARRRRRHHHHHH!*

Just when Rio had reached the stairs leading downwards, an extremely loud voice resounded in his ears.

It was as if someone was screaming in fear at the top of his lungs.

*ARRRRRHHGGGGHHH STOPP!! AARRRHHH*

Hearing those wails of pain and fear coming from the lower floor, Rio hesitated from moving forward a little bit.
