Synopsis: The Supreme Demon Of Mount Hyungsan

One hundred children trapped in Mount Hyungsan. Only one, ‘Dan Hyung-woo’, came out alive. He survived the hell created by the Heavenly Schemer, and in return, gained power worthy of being called a Demon God, but the world is unfamiliar, and he does not understand its rules. So he became an escort for the Henan Escort Agency.
