I Become an Upright Magistrate in Ancient Times with a Soul-Swapping System

Ran Chaoyu transmigrates to ancient times and binds herself to a Soul-Swapping System, which lets her choose any living being except herself to swap souls with.

From the start, she's stranded in the wilderness. When a scoundrel tries to take advantage of her, she makes him swap souls with a rock and escapes.

When the kind widow who takes her in is falsely accused by that scoundrel of kidnapping a child, Ran Chaoyu makes the widow swap souls with him. Speaking through the scoundrel, the widow reveals the truth, clears her name, and makes sure the villain faces justice.

…

With her soul-swapping ability, Ran Chaoyu lets victims speak the truth through their abusers, ensures the wrongly accused don't die in despair, and makes sure evildoers can't escape justice. The common people respectfully call her "Little Blue Sky."

…And then she catches the attention of another "Blue Sky," Judge Gu.

Judge Gu: "Miss A-Yu, let's work together on cases and bring justice to the world!"
