Three years ago, Shen Jianwei was the most dazzling noble girl in the capital, loved by her family and her childhood sweetheart.
But she didn't expect that a well-planned massacre would leave her family in ruins and fall into the abyss.
Three years later, she took the identity of her benefactor and married into her enemy's house.
The whole capital was betting on how many days that merchant girl from the south of the Yangtze River could survive in the cannibalistic Hou Mansion.

Because she is here to send everyone to hell.
