Born again as a nameless s*ave, Kang Geohan(Kang Strong), with the memories of his past life on Earth in the 21st century, aims to break free from the life of a s*ave in the magical and steel continent of Raniakea. To do so, he must become a gigant rider by lifting the ‘Stone of magic’. “Stand up straight!” “Clench your buttocks!” “Take a deep breath from your belly!” Using his knowledge from his previous life as a trainer, he accumulates magical power like working out, and climbs the ladder of the hierarchical society. “Well, then I’m going to get some food for my chest…” [Ting! The magic is growing faster.] Amidst a steam engine-like explosive growth and a battlefield of clashes of steel!
