Born with impaired meridians and deemed hopeless in immortal cultivation, Ling Chen, a miscellaneous servant of the Qingyun Sect, unexpectedly relies on an ancestral Qinglan jade pendant to defy the heavens and change her fate, overturning the sect's millennia-old unjust rules from the muddy bottom! The Qingyun Sect determines nobility and cheapness by spiritual roots and distributes resources by background. Ling Chen, as a female cultivator with impaired meridians, was demoted as an outer sect miscellaneous servant, enduring years of bullying by Senior Brother Nie Kui, having her spiritual herbs deducted by Steward Wang, and being framed for hiding forbidden drugs, nearly being expelled from the sect. In dire straits, she awakens the jade pendant's supernatural ability, which can refine medicinal power and repair meridians. Since then, she plays dumb and endures by day, tempers her body and refines medicine by night, and creates her own pharmaceutical combat method, completely breaking away from the sect's alchemy system. In the outer sect sparring, she defeats strong enemies one after another with her impaired meridian body, slapping faces on the spot.
