Throne of Divine Runes

The Divine Path and Tales of Demons and Gods

Has no one written a story set in The Sacred Ruins or Tales of Demons and Gods where there's a System that lets the protagonist level up and grow stronger by killing demons, and where the System's shop sells all kinds of things he wants? He could also collect beautiful women, then eventually recover his original body or memories, defeat the Holy Emperor, and live happily ever after.
