471 Threat

This was a pitch black hall.

If not for Darksight, Marvin wouldn't have had a chance to notice the Black Dragon beforehand.

He used Stealth while grasping Weeping Sky and slowly approached.

He chose to watch for the moment and not act rashly.

Marvin looked on as the Black Dragon grabbed them one by one and tore them to pieces.

As for the pages left behind by the ancient books, she carefully collected them.

She apparently hadn't noticed Marvin, this was a good news.

'She seems to be going toward the library.'

'Could the entrance to the 3rd floor be related to the library?'

Marvin's current knowledge about this whole situation was very limited, but he knew that the Chromatic Dragons would definitely rush to the 3rd floor before entering the Nightmare Boundary.
