In the depths of the underground world lived the descendants who were born and raised by feeding on the teats of beasts.These individuals with special abilities and enhanced physical abilities were known as dungeon babies.Amongst them, Kim Jin-Woo was born in the labyrinth on the lowest floor."I've never tried to become strong. I just wanted to survive."This is a story of a lowly tunnel digger who ascends the throne to become the king of a labyrinth.
After being summoned in this other dimension world, all of the people that were summoned had their classes awakened. As someone that doesn't even know English, Kim Sunhyuk had awakened as the lone Dragon Rider. But wait, there are no dragons?!?! They looked down on him, shunned him for being worse than a regular soldier, and called him a dragon-less rider. But little did they know that he would soar the skies on one above them.
