After outer sect disciple Gu Xingzhou of the Qinglan Sect masters the Lamp Guiding Art, he discovers that Shen Zhiwei's destiny lamp is weakening in sync. The two investigate the lamp registers, old contracts, and protective array records, finding out that her destiny fire has been channeled into the western third array eye by an old contract since childhood, suffering long-term depletion while being kept secret. Gu Xingzhou participates in repairing the alternative lamp array, takes honest responsibility after a trial array failure, and everyone clears the channels section by section, re-checks the retaining walls, and establishes public rotational shifts and exit procedures. Shen Zhiwei finally voluntarily revokes the old contract so the protective array no longer draws on her destiny fire, and Gu Xingzhou passes his make-up exam as the two continue their cultivation and patrol the lamps together.
