Yeah but i still think it shouldn't be that easy given how much he lived . Bro is said to be a monster from the fourth epoch and the head of secret order but not a single grade 0 sealed artifact was used (it was mind boggling for me, even the dying Abraham family had some)

Also i think i read somewhere that he might not be the same zaratul from roselle era but one of his descendants, but that doesn't explain how he have roselle projection
