Null: "Lifeblood never fails to extend a life... And it never will."
*Null grabs one of his horns and cracks his own head open, revealing a bunch of Lifeblood within*
Null: "It knows when you'll die... And when you do, it'll kill itself, and it contains enough Lifeblood to bring you back from the dead... Your body will absorb the Lifeblood..."
