Vampires and the Undead

As the third part of the "Vapa" series, the story mainly revolves around the ancient war between vampires and necromancers. "The final showdown is not completed on the battlefield of strength, but on the definition of the word 'living'. Do you use it to define grabbing and manipulation, or do you use it to define giving and protecting? Do you use it to prove that you can live longer than everyone else, or do you use it to prove that some things are more worthwhile than living itself." This is not only the dilemma of an existence imprisoned in an immortal cage in the book, but also an eternal question that a life swinging between finite and infinite must face in a quiet moment.
