The orphan Shen Li, gravely ill, was rescued and cared for by Gu Yanchi and his family. Years later, Gu Yanchi confessed his love to her, only to shock the entire city by massacring the Gu family on the eve of their wedding. Yet the truth ran far deeper. It was all a conspiracy by Ye Yun'er, who, jealous of Shen Li’s bond with Gu Yanchi, exploited Gu Shizhen’s guilt to manipulate Shen Li into becoming a tool for murder. Unbeknownst to her, Shen Li had already seen through the scheme. By swallowing a Truth-Seeking Gu, she exposed the reality, laid bare Ye Yun'er’s crimes, and brought her to justice.
