I am looking for the title of this novel he is a mc who has the power to enter a virtual reality game in advance when he entered he was in the body of an NPC, not just anyone, a vampire mage who has the particularity to be the vampire king who can walk in the light of day, sometime before the story of this vampire king's kingdom was attacked almost destroyed and he lost most of those powers, when the mc takes back the horn from this vampire king he will start reforming the remaining vampires of his clan telling them that they are different that they are descendants of the god of creation to name the light vampires and will start building an empire over them.
