lets say that brook eats a random devil fruit first. and then he eats his undead devil fruit. brook would die imediatley but his soul would survive and would start searching his body. but since brook died his first df would respawn somewhere near him. the devil fruit resides within one's body and not one's soul since the devil fruit is supposed to be a seperate demon soul living inside your body givin u the powers.
