Negris was rather baffled upon hearing about the Undead Sacrifice, for he couldn't connect the death of a living person from exhaustion to it.
The Undead Sacrifice doesn't involve living people, it's about sacrificing souls.
The Undead Sacrifice is a method for the living to transform into undead creatures. By sacrificing their own souls, they can retain their memories from when they were alive, just like Lisa, who became a witch through the Undead Sacrifice.
This is no profound secret technique, it just has a low success rate. Many people have been reborn that way, but they were unable to retain their memories or, in worse cases, their intelligence ended up reduced after their transformation.
But, anyway, the Undead Sacrifice doesn't require killing a living person. What is this cloud of smoke talking about?
