The King of Hell’s Notice, the Soul-Chasing Lock

I inherited my grandfather’s old bookstore, only to discover a strange old book that couldn’t be sold. Its pages were bound in human skin, its ink looked like dried blood, and the title page read, “Anyone who finishes reading this will die within seven days.” The first customer dropped dead that very night, with paper offerings from the book scattered beside the body. I tried to burn it, but countless tormented souls wailed from within the flames.
