Grilling meat over a campfire and letting its aroma fill the cave ran contrary to the objective that Yang Chen was trying to accomplish by staying here and using the [Dread Wind Powder] to hide his presence from the demonic beast.
Naturally, he knew this fact which is why, he had set up the [Silent Sanctuary] which can block out even the sound and smell around the cave. Thus the reason why he was celebrating so carefreely.
"Munch… much… how long have I been staying inside this cave" As he munched on the meat, he questioned the demon who was perched atop his head. This demon was completely taking his head for a nest.
"Hm? This time, your breakthrough took some time. So if we calculate all the days you have spent here, it should be more than a month" Amon replied.
Since it was natural to lose the sense of time during cultivation, it was not unusual for Yang Chen to not realise the time.
