The Celestial Diagram Institute has always judged the strength of formation diagrams by the number of nodes, believing that bigger is better. Fang Xuchuan, a low-ranking formation checker with only mediocre spiritual power, discovers through years of error-checking that connection structures, not sheer scale, are the true foundation of a reliable formation diagram. He joins forces with diagram draftsman Bai Zhiju to develop the Looping Diagram Method. After facing a false-connection assessment and competing against other formations at the Grand Formation Tournament, they use structural ingenuity to unravel the Myriad Lines Self-Healing Formation, ultimately persuading the institute to rewrite its formation rating rules.
