Xiao Yang, a delivery boy whose parents both died, accidentally activated the "Jianghu Fishing System" while delivering orders. He can obtain martial arts secrets and training resources by fishing in different waters. He fished out the Taizu Changquan from the community pond and rescued Su Qing, a school beauty who was a race car driver who was harassed by the underworld. He was thus involved in the disputes of the modern hidden martial arts world - major aristocratic families were fighting openly and secretly for the "core of the secret realm" that could break through the martial arts saint. With the help of the system, Xiao Yang has successively mastered top martial arts such as Nine Yang Magic, Yi Jin Jing, and Eighteen Dragon Subduing Palms. He defeated the Murong family master and the leader of the dark forces, and gradually grew into a martial saint. He eventually protected the peace of the city and joined hands with Su Qing to move to a higher dimension.
