A day passed.
Nothing eventful happened the previous night.
It was all calm and peaceful, which made him feel all the more unsettled.
The more peaceful it seemed, the more he felt that trouble was about to strike.
His sixth sense, although tingling very little, further confirmed his instinct and made him feel the urge to take care of his affairs.
It was still early in the morning, and he had just woken up, but he immediately got to work.
He lay on the bed in his room, taking out the core purifying book from the pocket dimension of the Void Orb and reading it.
He discovered that dungeon monster cores could be purified by soaking them in holy water for several hours.
Holy water could be created by infusing purified water with holy power.
What was purified water? It was water that only wizards could create.
