Worthless Profession: Dragon Tamer is a story about Lu Fan, who receives the "Dragon Tamer" hidden class, which is widely considered useless because taming a dragon is believed to be impossible. In a world that combines reality and a game-like system, Lu Fan is given the "Dragon Tamer" class on the day of his class transfer, surprising everyone. The series follows Lu Fan as he uses his awakened "Super Treasure Map System" to succeed where no one else has, making the "weakest" class the strongest.
