Feng Zhiwei, who was born in a low-class immortal cultivating family, was betrothed by her family to a talented disciple of the Qingyun Sect since she was a child in order to gain access to the powerful. However, on the day she entered the family, her ex-fiancé broke off the engagement in public and ridiculed her for "her spiritual roots are mixed and her destiny is like grass." She was even humiliated and expelled by the sect's deacon, making her the laughingstock of the entire sect. In a desperate situation, she accidentally activates the synthesis system of all things - a heaven-defying golden finger with "synthesis of skills as the core".
The system rules are strange and powerful: synthesize techniques or items without side effects to generate normal advanced products; if the original techniques have side effects, the side effects will be randomly reversed after synthesis, and strengthened to a heaven-defying effect ten to a hundred times! For example, practicing a forbidden technique that would originally shorten one's life by ten years can actually extend one's life by a hundred years after being synthesized; the fragments of a scroll that would have burnt one's heart and caused a fire, turned out to be "immune to inner demons and invulnerable to a hundred calamities."
Feng Zhiwei started out as a wasted girl, and used scraps of scrolls, miscellaneous books, and even floor-sweeping formulas to create a secret code of magical skills that shocked cultivation. On the surface, she is still the sleepy and gluttonous senior sister, but in fact, she secretly controls the "black market of martial arts" and allows countless geniuses to rush to practice the "poisonous martial arts" that she "randomly synthesizes".
