Guo Fan was a very special necromancer, too, his uniqueness lay in his ability to swap places with the "person" in the spirit tablet photo he held in his hand.
It would be more accurate to say he swapped with a ghost rather than a person.
The old and eerie spirit tablet concealed a real ghost, no one knew where he had found such a terrifying object, nor did anyone understand why he had become a necromancer; they only knew his ability was extremely valuable under certain circumstances.
While holding the spirit tablet and walking forward, Guo Fan, having transformed into a true ghost, could handle almost any dangerous situation.
Because ghosts do not die.
Even when faced with S-class paranormal events, he was completely confident he could survive.
Never underestimate the significance of these three words: to survive.
