Poisoned at the Start? Sorry, My Eldest Daughter, She Is a Forensic Doctor

Wen Yan, a top modern medical examiner, traveled through time and became Bai Yueguang, "Gu Xiwei, the legitimate daughter of the Duke of Guo" in the ancient sadistic novel. In the original plot, she died of lovesickness, and Prince Jing held a grand wedding banquet for the substitute Bai Lianhua. But Wen Yan immediately discovered after traveling through time that this was not death from illness, but a carefully planned murder by slow poisoning.
