From Slime to the Great Old Ones

On the first day of time travel, when I escaped from the steam city, people called me a "disgusting slime monster". After two and a half years of leveling, I conquered the land of corruption, and people called me the "indescribable faceless king." After decades of leveling, I penetrated the abyss of the sea, and people prayed to me. "The all-devouring Lord of the Abyss." … "O God, please listen to my prayer, the original ancestor of all life, the indescribable faceless king..." "Stop, stop, stop reading, I'm just a slime, I've finally reached the full level!"
