Comments of chapter undefined of Monster Paradise

Can't he just use the vampire as a ride? Sure it would look ridicilous getting a piggyback by a vampire but it should be possible. With that vampires strenght which is atleast 10 or even more times that of a human i doubt it would be a problem for it to carry mc for a long time... Actually vampires never tire as long as they have blood right? Vampire could feed on whatever monster they come up against on their way and keep going 24/7 even when mc is sleeping on his back...
