Fang Hong's heart skipped a beat.
This lich actually knows the relationship between the Rogsel Family and this castle. Who exactly is it? Or could it originally be the owner of the castle, having encountered some issue when transforming into a lich, thus causing Aimumu Fortress to become what it is now?
Yet he and Hilveld hadn't heard of any previous owners of Aimumu Fortress having studied magic. Not even Magic Guided Conductor, let alone Alchemist.
However, it can't be ruled out that the truth was intentionally concealed, as certainly no one would openly announce they are studying undead spells.
But Fang Hong also found it strange. If the opponent has always been in the castle, is it possible it doesn't know that the cat lady named Daisy can lead people into the underground?
Speaking of which, he just realized that Daisy and Miss Tata were nowhere to be found. Even calling out mentally yielded no response, only a faint tremor coming from deep within.
