A Poor Girl, Forced Into Marriage, Becomes A Royal Concubine With Her Child

Sang Wanwan, a top-tier special operative and master of ancient martial arts and toxicology, dies in a laboratory explosion and awakens in the body of a girl with the same name in the Great Yin Dynasty. The original Sang Wanwan was the true daughter of the Marquis Zhen Guo's State, returned to the family after sixteen years in the countryside, only to be betrayed by her father, Sang Deben, and her father's favored foster daughter, Sang Rourou. The Emperor had decreed that the legitimate daughter marry the Ninth Prince, Zongzheng Zhan, a man rumored to be a violent, mentally impaired fool and a cursed lone star whose previous fiancées had died mysteriously. To save his beloved foster daughter from this death sentence, the Marquis forced his biological daughter into the wedding instead. Driven to despair, the original Sang Wanwan had taken her own life, allowing the modern operative to inherit the body and vow revenge.

On the morning of the wedding, Sang Wanwan breaks free from her bonds, incapacitates the abusive wedding matron Nanny Wang, and confronts her father and Sang Rourou. When Sang Deben threatens to deny her mother's massive dowry unless she complies, Sang Wanwan slaps him with enough force to break his teeth and chokes Sang Rourou, declaring that she will take the marriage in her sister's place if it means settling scores. Just as guards are about to seize her, an imperial decree arrives announcing that the Ninth Prince has been convicted of treason. His titles are stripped, his assets confiscated, and he is sentenced to exile in the deadly Kuhan Province. Sang Deben and Sang Rourou immediately disown Sang Wanwan, hoping to distance themselves from the disaster, but the eunuch reveals that the marriage contract is already valid, making her the wife of a traitor.

Before being taken to the capital's detention woodshed, Sang Wanwan's blood activates a mysterious black wooden ring, binding her to the "Infinity" Department Store and Ecological Space. This supernatural inventory allows her to store and retrieve items from a massive, time-frozen warehouse containing modern food, medicine, weapons, and machinery. That night, she escapes the woodshed by knocking out the guards with ether and returns to the Marquis Manor. She infiltrates her father's study, renders him and Sang Rourou unconscious, and systematically loots the estate. She steals the underground treasury filled with gold and silver, empties Sang Rourou's luxurious bedroom, clears out the kitchen supplies, and even removes the marble flooring and roof beams from the main hall, leaving the manor a hollow shell.

Her heist does not end there. Upgrading her space to Level 2, Sang Wanwan infiltrates the imperial palace and raids the Emperor's private treasury. She steals mountains of gold, rare artifacts, and medicinal ingredients, leaving behind a taunting message written in her blood on the wall. The Emperor suffers a stroke upon discovering the theft and collapses, plunging the capital into chaos as the city gates are sealed to find the thief. Meanwhile, Sang Wanwan returns to the woodshed and sleeps beside the Ninth Prince, who appears to be a simple-minded fool but is actually the legendary God of War.

The next morning, the exiles are marched out of the capital under the brutal escort of Zhao Tieniu, who had been bribed by Sang Rourou to torture Sang Wanwan to death. Bound in heavy chains and subjected to the harsh conditions of the road, Sang Wanwan remains calm. She possesses vast wealth, endless supplies, and a husband who may not be the fool he appears to be. As the group faces the deadly journey to Kuhan Province, Sang Wanwan is prepared to use her modern knowledge and supernatural space to survive and dismantle everyone who wronged her.
