SSS-Class Revival Hunter

In the mysterious, RPG dungeon-like Tower, Gongja Kim lives a mundane existence, envying all the star hunters. One day, his wish for more is granted with a legendary skill to copy others' abilities… at the cost of his life. Before he can make sense of it, he's killed by the #1 hunter, the Flame Emperor! But this activates his skill and now he's copied a new one, the ability to travel back in time upon death. How will Gongja use these skills to outplay the competition and rise to the top?
