After My Soul Was Taken by Mistake, I Led the Marquis to Loot the Capital and Face Exile

Xin Long, a successful food content creator and survivor of a past zombie apocalypse, dies after saving a child from a traffic accident. She arrives at the Underworld Service Office, where an automated Soul Collection System mistakenly identifies her as a forty-year-old male convict named Xing Long. The system, which has been in trial operation for a year, initially refuses to acknowledge the error. However, upon seeing her ID, the clerk discovers that Xin Long possesses an unprecedented one hundred million merit points, a figure the broken system cannot process. The Underworld supervisor informs Xin Long that her physical body was too severely damaged to be revived. Consequently, she is offered transmigration into an ancient world as compensation for the bureaucratic error.

Xin Long accepts the offer and transmigrates into the body of the Grand Princess Chang, an eighteen-year-old woman who died of a heart attack while carrying a fake Imperial Jade Seal. The original owner of the body was a naive girl obsessed with her half-brother, the Emperor, who manipulated her into framing the Duke Dingguo, Xiao Jinghe. In the previous timeline, this betrayal led to the exile and brutal death of the entire Xiao family. Upon arriving in the Duke residence, Xin Long encounters Xiao Jinghe, who has been reborn with memories of his tragic past. He immediately suspects her of betrayal and holds a sword to her throat, demanding the location of the seal. Xin Long reveals that she is not the original princess and offers to help him save his family in exchange for half of their wealth upon reaching their destination in Lingnan.

Xiao Jinghe, desperate to prevent history from repeating itself, agrees to the partnership. Xin Long utilizes her dimensional storage space, a gift from the Underworld that connects to her modern apartment, to hide the family's valuables and stockpile essential supplies. She also uses a listening device to monitor the household dynamics. That night, she dons black clothing and infiltrates the residences of corrupt officials involved in the impending raid, including the eunuch Rui'an and Prime Minister Yan Lexian. She loots their ill-gotten wealth, food stores, and treasures, setting fire to their estates to cover her tracks. This strategic looting ensures that the Xiao family will have resources during their exile while depriving their enemies of their assets.

The following morning, Eunuch Rui'an arrives with imperial guards to search the Duke Dingguo residence for the fake seal. Because Xin Long had already hidden the seal and emptied the house of valuable items, the guards find nothing. Despite the lack of evidence, the Emperor still issues the decree for confiscation and exile. The Dowager Madam and the six sisters-in-law, initially skeptical of Xin Long, are convinced by her warnings and prepare for the journey. Xin Long releases her loyal maid, Qiuyue, granting her freedom and a sum of money to start a new life. The story concludes with the Xiao family facing the imminent hardship of exile, armed with hidden supplies and the alliance of a transmigrated spirit who holds the key to their survival.
