Firstly, he notices the dark fog had turned into a world made of white mist. Some parts of it appeared to be dim, while the others were a bit hazy.
In his line of sight, he could see a black hazy silhouette swiftly moving through the fog, its features were hazy due to the fact it's was within the innermost part of the hazy fog.
Tobi could see these fogs would occasionally become hazy the moment the hazy silhouette move toward the particular part, then become hazier after that.
'An invisible enemy doesn't mean it's undefeatable. There is no need to fear it.' A muffled voice suddenly said in his mind.
At this moment Tobi was now sure, Horus was probably giving him hints and making things much easier for him.
Secondly, instinctively he notices his mind and body were naturally calmer than usual, as they began to operate in unison.
'By infusing yourself with fire elemental Mana, you could burn up the fog around you' The muffled voice replied to Tobi.
