Shen Yan, a bottom disciple in an ancient martial arts school, was knocked unconscious by his fellow disciples and traveled to modern times. He was possessed by Lin Mo, the "ultimate dog licker" of the university's Taekwondo club. The original owner was submissive and wanted to please the goddess Su Qingyan without any bottom line, and was ridiculed and bullied by the entire society. After Shen Yan possessed him, he completely lost his humble status and used ancient martial arts skills to defeat the club bully Jiang Chen with one move, which shocked the whole audience.
Su Qingyan, the taekwondo goddess who others think is extremely talented and comes from a wealthy family, is actually trapped by the inner demons of being a black whistle in the competition field when she was a child. She always makes mistakes in key games, and is even forced to marry and retire in the name of love by her parents. Her glorious life has long been shackled to the point where she can't breathe.
The appearance of Shen Yan broke the established life trajectory of the two people. He used ancient martial arts Zhuang Kung Fu to help her stabilize her mind and break her inner demons; she used the professional modern Taekwondo system to help him adapt to the rules of the competition and stand firm in the modern arena. From the club assessment to the municipal triple crown, from the mixed doubles first match to the provincial journey, the two fought side by side and achieved two-way redemption. Using a new system that integrated ancient martial arts and modern taekwondo, they beat the top players from various countries. In the end, they both reached the top of the world arena, jointly created a new fighting school, and completed the inheritance of ancient martial arts and the fulfillment of life.
