Qin Yun was once a gifted hunter. His double-A talent for power and speed allowed him to stand out in the "Tower" trials. However, due to family changes, his parents died in a car accident and his sister Qin Yu became a vegetable. He was forced to give up his career as a hunter and became a low-level masseur in Guancheng. In order to raise money for his sister's medical expenses, he kept his name anonymous, but while working part-time at a high-end club, he accidentally broke into a secret gathering of high school student Bai Yueguang and Lan Xianya. The class beauties who used to have feuds over drag racing have now become upstart hunters in the elite circles, and Lan Xianya has become a legend in the hunter world as an S-class hunter.
In a car accident, Qin Yun made a deal with the mysterious demon "Qin Yu" to exchange for a glimmer of life at the cost of twenty years of life. When Lu Yifan, the heir to the Lu family, tried to silence him, Lan Xianya's appearance reversed the situation, and the long sword on her waist that sealed the holy sword "Eldia" hinted that the entanglement in the fate of the two went far beyond that. Qin Yun gradually discovered that his sister's "leukemia" was actually a lie made by the devil, and the "plunder" of his lost talent was the key to uncovering the truth.
In order to regain his power, Qin Yun was forced to cooperate with the devil and infiltrated the Hunter Guild in the name of "plunder", but found that he had already become a pawn of many forces: the Pluto Guild's pursuit, the Pangu Guild's wooing, Lan Xianya's hesitant protection... Under the shadow of the tower, he had to decide whether to regain his talent and become a hunter, or to protect the remaining family ties with a mortal body? When Lan Xianya's sword points towards the "Hognier" lair, and when Qin Yu's devil contract resurfaces, this hunt about redemption and revenge will eventually tear apart the peaceful daily life.
