Lin Changkong was tested by the Qingyun Sect as having mortal-grade spiritual roots, leaving his immortal path virtually cut off. Yet right before ascending the heavenly stairs, he awakened the Primordial System, choosing to automatically elevate by one realm every year. After becoming a miscellaneous servant in the Scripture Pavilion, he swept floors, read books, practiced swordsmanship and array formations, and secretly protected Luo Qinghan, Qin Hao, and the Qingyun Sect. Amidst the crisis in the Qingyou Secret Realm, he slew strong enemies with his sword, burned his golden core to save people, took in three little ones along with a beast king's battle power, repaired the sect-protecting grand array, and pushed the Qingyun Sect toward the eve of a great battle.
