Female protagonist, originally the legitimate youngest daughter of the Champion Marquis Family but swapped at birth by the Shen merchant family. In her past life, she schemed to elevate her adoptive father from ordinary merchant to Imperial Merchant, made her eldest brother Prime Minister, her second brother Protector-of-the-Nation General, and her third brother controller of Da'an's economic lifeline. She also placed a rescued refugee husband on the throne as The Most Exalted and became empress. However, on her coronation day, her father, brothers, and husband betrayed her, accusing her of witchcraft, torturing her, and killing her to steal the Supreme Treasure in her portable space. She was reborn to age sixteen, just before the Champion Marquis Family was sentenced to exile. She cleverly negotiated to switch back with the Shen family's biological daughter, Su Qingyan.
