I Started a Substitute Marriage, and My Fiancé Turned Out to Be a Golden Egg.

[Starting substitute marriage + science fiction romance + mutual redemption + tearing apart the conspiracy + double cleansing] Being framed by a gang of scumbags, Su Manxing almost died on the wedding day. When she opened her eyes again, she became the foster body of the "Retrospective" group. In order to survive, she accidentally married the fourth prince, and got a gold jade bracelet. She used his profit to investigate her own case, vowing to expose the scumbag and his inhuman experiments to the public. But after she collected the evidence, she discovered that it was stamped with the official seal of the world of power, wealth, and sex. The superiors knew and acquiesced. In despair, she looked for a new way back and a new direction.
