Lin Chen transmigrates to the Qingyun Sect and becomes an outer sect disciple because of his mixed spiritual roots. There, he encounters Xiao Ling, a palm-sized spirit. Xiao Ling cannot help him cultivate and can only analyze cultivation techniques and formations, so Lin Chen persists in repeated verification and hands-on practice to make up for his shortcomings. Starting with anomalies in the spiritual fields, he progresses to the inner sect's formation-breaking assessment and protects the core of an ancient ruin and a spiritual-vein village in a secret realm. Throughout it all, he adheres to evidence and rules, investigates clues alongside Su Qingyao, and helps Zhao Hao learn to take responsibility. When Elder Zhou's greed leads to a false accusation, Lin Chen clears his name through a public demonstration and complete evidence, bringing the crisis to an end. Xiao Ling merges into the space between his eyebrows, and Lin Chen gazes into the distance alongside Su Qingyao, embodying the path of steady growth and protection.
