The thin guy was slowly but surely making his way through the narrow ventilation hole – the square tunnel inside the pyrobloin wall. No sane person would even think that it is possible to get in there at all, so there are no traps.
Kyon cleverly used his full body control ability. However, it wasn't just that. If his bones had not been replaced with carbon ones, it would not have been possible to soften them with the earth element, and in this case the scout would have been stuck at the first turn, of which there were thousands.
By the way, the 5th floor seemed huge not only because of its long corridors, but also because of the chaotic location of the premises, that is, an earthen layer often lay between them, therefore, it will not be easy to find a secret room, if one exists.
Moving through the ventilation, he saw a man in a mask below through a small gap… In black, not gray! The servants of the empress wore gray masks, and the servants of the 0th general wore black masks.
