Chu Fei, a poor unaffiliated formation master, ventures into Shadow Valley in search of a chance to turn his fortunes around. Relying on his understanding of formation rules, he deceives the natural barrier, only to become entangled in the Mo family's struggle for the Nine-Leaf Stargrass. During his escape, he meets Ye Qingluo, a professional treasure hunter. Their relationship develops from a mutually beneficial partnership into one of mutual support as they repeatedly break deadly formations in snow caves, quicksand fields, and underground ruins. Hunted by Mo Wuhen, Chu Fei turns the rules of spatial resetting against his pursuers and seizes the core map. In the end, although both have exhausted their spiritual energy and suffered severe injuries, they support each other into the Hundred Thousand Mountains, protecting the map and preserving the hope that intelligence and trust can lead them out of desperate situations.
