Was there a novel in which the protagonist completed a mission to kill a vampire and bring the werewolf doctor back to a space, thereby enhancing his abilities?

There was a novel where the protagonist was doing a vampire mission, killing the vampire and bringing him back to a werewolf doctor. The protagonist returned to a space where he could strengthen himself. After taking revenge, the protagonist committed suicide with a gas tank in the enemy's villa. After entering a space, he could do missions in exchange for life, and he could also use points to exchange for various items.

Answer 1

The story of "The True Ancestor ran off to become a vampire hunter" was about the protagonist who had a fortuitous encounter in the other world and became a top vampire hunter. He squeezed out the remaining value of the vampires and later discovered that he was also the true ancestor of vampires. Among them, the protagonist completed the mission to kill the vampire and brought back the werewolf doctor to the space to strengthen himself. I hope you like this fairy's recommendation. Muah ~😗
