Su Yao, an ordinary web-novel editor, unexpectedly gets bound to a quick transmigration System and begins a journey through countless small worlds. She has only one task: possess the bodies of ill-fated supporting heroines, break the chains of injustice that bind them, and turn their tragic endings around.
From a good-for-nothing disciple framed in an ancient fantasy world of immortals, to a revolutionary daughter born to a concubine and imprisoned amid the chaos of the Republican era; from an ordinary girl overlooked in a corner of her school, to a female soldier discriminated against in a starship mech cockpit; from an NPC about to be deleted in a holographic game, to a survivor struggling to stay alive in a post-apocalyptic wasteland...
The supporting heroine in each world carries a resentful grievance: talents stolen, dignity trampled, life rewritten, or sincere love betrayed. Armed with modern knowledge and an unyielding will, Su Yao holds the fragments of the original owner's lingering obsessions and finds a way through schemes and conspiracies, rising from the depths of desperate situations.
She exposes the dark secrets of the immortal sects with her mastery of poisons, protects her country with strategy amid the chaos of war, shines on the school grounds with her talents, and races across interstellar battlefields with her mech combat skills. She makes loyal friends who stand by her through thick and thin, exposes towering lies, and, with every comeback, unlocks the mysterious connection between herself and the small worlds.
As the cold System gradually grows warm, and her determination to complete her missions transforms into reverence for every soul, Su Yao finally understands: true glory has never meant climbing to the top by stepping on others. It means helping every soul betrayed by fate reclaim the dazzling light that belongs to them.
This is a salvation that crosses time and space, and a legendary comeback story belonging to the supporting heroines.
