Devouring the Heavens: I Rely on My Waste Body to Kill Through the Immortal World!

Here Is a Cool Article, from Beginning to End,

There is no heroine. If there is one, don't use the Virgin. It needs to be a decisive killing, killing from beginning to end. History, technology, wilderness, mythology, etc. Are all acceptable. As long as there is a murder story, it's okay if it's not here. Post the title of the book and I'll find it myself.
