In the winter of the 16th year of Yongping, Shen Heng, an orphan girl from western Hunan, was taken into the Shen Mansion in the capital. She thought that all her hardships would be rewarded, but she didn't know that she was just a chess piece sent to the Marquis' Mansion for happiness. The newlywed husband, Gu Yanzhi, the prince of Zhennanhou, is lingering on the bedside. His life is on the line. Everyone is waiting to see this country bride become a widow. Shen Heng put on her wedding dress quietly without crying or fussing - instead of begging for mercy in the Shen family, it would be better to go to the Hou Mansion to fight for a way out. But she gradually discovered that Gu Yanzhi's illness was fake, the peace in the Hou Mansion was fake, and even her life experience hid a huge secret. When the battle for the right to inherit the throne turned this deep mansion into a Shura field, Shen Heng realized that she had never been a pawn, but a knife that had been carefully sharpened for sixteen years.
