Dante assumed that more than a day had passed since the incident. Naturally, he wouldn't be concerned about time, but now time was a matter of life or death. Nagasawa was on his back as he carried her through the narrow tunnels of the dungeon.
He wished he had time to rest, but he couldn't afford it. He needed to find food as quickly as possible. The moment he found food, he could quickly improve. Due to the malevolent sensation of the mana in this layer, Dante chose not to absorb it and pressed on. The damage from absorbing such mana could be dangerous, and he couldn't risk it anymore; he needed to survive for both of them.
In fact, it was risky for him to absorb this type of mana, especially because he had holy magic. It could completely corrupt his core and turn him into something he resolved not to even think about.
He was holding up well, but he needed to expedite Nagasawa's situation. She had already taken the pill he found with the unlucky group.
