Synopsis: Returning With Absolutely Nothing

Aeria is a world that summons folks from different universes, and those who are weak are doomed. Sungmin Lee, an inexperienced mercenary, is not exempt from this fate. However, he comes into possession of a mysterious object that thrusts him into the past before he meets his untimely end. As a 13-year-old with a second chance, Sungmin takes on the tough task of becoming the strongest in Aeria, even though he lacks money and talent. The query is: can a poor boy with pure drive become a hero?
