Joo Hyun, an ordinary salesman in the 21st century, is suddenly thrust into a mysterious, endless Tower that connects countless worlds. Chosen as a player, he gains the unimaginable power of infinite attributes, skills, and talents—but with a limit on how many he can select at a time. As he climbs the Tower’s floors, each more perilous than the last, he faces not only formidable monsters and deadly trials but also illusions that test his mind and willpower. With each victory, he grows stronger, but the cost of power becomes clearer. Surrounded by strange allies, mysterious enemies, and the growing weight of his abilities, Joo Hyun must decide: will he keep climbing to the top to uncover the truth of the Tower, or will the challenges of this surreal world break him before he reaches his goal? His journey is one of growth, self-discovery, and sacrifice, where every decision could mean the difference between life and death.
