Li Yan is running out of time. A gifted martial artist, he has only a few months left to live because of a terminal illness. At his lowest point he happens upon a man calling himself Tapir and is sent into a fruit of the Yanfu Fruit Tree. There, a system hands him three tasks to finish before a deadline. He fights in boxing matches to earn money, trades it for Yanfu points, and hopes to use those points to buy a medicine that can cure his illness. The more he learns about Longyuan Fortress, the place he now finds himself in, the more he is pulled into the conflicts within its walls. He also realizes that other Yanfu Walkers are quietly competing against him. The result is a fantasy action ONA built around martial arts bouts and a race against a deadline.
