Reincarnated as the Skeleton King: Starting with the Great Tomb

[Villain Protagonist + No Saintly Goodness + Misunderstandings Galore + Ruthless + Wild Imagination + Wish Fulfillment] Lin Luo was an ordinary programmer at a game development company. One day, after dying from a long stretch of voluntary overtime, he was reborn in the world of the game he had helped develop. He had become a game character he himself had created: the Skeleton King. And he wasn't the only thing from the game to appear in this world. There was also an underground tomb called Calandia. The System that came with him only left Lin Luo more confused. [Kill more living beings and feed them to the tomb to unlock more of its permissions.] The Great Tomb of Calandia had nine levels, each containing rare treasures or peerless cultivation techniques. Even the most ordinary item was at the super-tier level. [The greater the intelligence of the living being you kill, the greater the reward. The highest reward for a single kill goes to... humans!] Now the Skeleton King and the absolute ruler of the Great Tomb of Calandia, Lin Luo sought to unlock all its permissions and ultimately find a way back to his original world. And so he began his path as a villain in the game world known as FNG!
