Kim Gong-Ja, a weak F-Class hunter without any skills, is envious of those who were blessed by the Tower. Letting his jealousy overcome him one day, Gong-Ja abruptly receives a S-Class skill that allows him to copy a skill from someone else—after they kill him. Sooner than he likes, Gong-Ja gets to test his newly acquired ability on the legendary hunter known as the Flame Emperor.

Receiving another potent skill that allows him to revive and go back in time by 24 hours, Gong-Ja devises a plan to travel 11 years into the past to eliminate the Flame Emperor and cement himself as the world’s best hunter.
