The Villainess Stole the Protagonist's Script

Qin Xiaoxiao had always enjoyed an easy life in her sect, loved by everyone as the daughter of the Island Master of Immortal Spirit Island. But during a trial in a secret realm, a spirit beast that had thrown itself into her arms told her that she was actually the villainess in an old-fashioned, tragic xianxia novel. Her fate was clear: once the male lead achieved his great ambition, her entire clan would be wiped out, her cultivation stolen, her immortal bones removed, and her banished to the wasteland. The spirit beast, which called itself the System, gave her one mission: stay alive until she could change her fate! After learning that she had gone from everyone's favorite to a supporting character, what could Qin Xiaoxiao do? Obviously... steal the male lead's script! Take his heroine and seize his opportunities. That's the only way to win! But why did the plot go off the rails as it went along? How did she end up in the villain's arms? And why did the System just confess that it was a mole? None of this was in the male lead's script...
