@32oiru well i don't know if it going to take the first person view to teased the reader but if not then yes since in the novel after the prologue
which he is dead he literally wake up later on not realizing that he already turn in to undead what more funny is apparently when he died and become a lower rank undead was the same time as the both dragon died so he who was near the top got bath with a lot of magic power making him special than other undead which is why he manage to survive long enough till he evolve to a high rank undead and the funny thing is the dungeon he went in got up on rank as well since the dragon mana which fill the ground as well which is why his evolution only take around hundred years
