"The Human Skin Book was crafted from the skin of a female Necromancer who practiced the Mysticism School of magic, and her hand bone was embedded in the cover. Furthermore, the content on the pages was written in ink made from her brain and blood. This is a very special spell, and apart from this spellbook, there should also be a magic wand made from her bones, and a vessel made from her skull to hold her heart and ashes." Chen Yu handed the transformed spellbook back to Gilles de Rais and explained the origins of the book.
However, Gilles de Rais was greatly astonished by Chen Yu's explanation. He did not reach for the spellbook that Chen Yu had returned, but instead asked him, "Why do such a thing?"
"For...," Chen Yu started, deliberately pausing for effect and giving Gilles de Rais a meaningful look before revealing, "Resurrection."
"Resurrection? This book can resurrect the dead?" Gilles de Rais, as Chen Yu had expected, was filled with interest and hope at his words.
