[Strong heroine + cold-blooded and ruthless + a heroine who loves to kill + mutual redemption with male leads from different worlds]
Gu Lengyuan was once an optimistic, cheerful, lively, and kind person, but she was forced to bind herself to a villainess System and travel to different worlds to complete missions.
As she completed more and more missions and advanced in rank, her nature gradually became twisted, and she grew increasingly bloodthirsty.
The Heavenly Dao feared her power and planned to dispose of her once she had served her purpose.
When the System discovered the Heavenly Dao's intentions, it could not bear to see its longtime companion vanish into oblivion. To save her, it made a solemn pledge to the Heavenly Dao: If I can make her bad, then I can make her good again!
But who knew? It's easy to become bad, but hard to become good!
