My sister was murdered. Who is the real murderer?

Elder sister was lying in a struggling posture in the bare trees, her clothes were torn, her crooked head fell into the trampled weeds, her throat was sealed by solidified black blood, and the falling camellia petals floated unevenly, forming a thick layer of Hua Zhong around her looming body, covered with criss-crossing wounds, and the wind mixed with the fragrance of wild flowers swept away the rot she had done.

Terrible suspicion sank into Lanting village. No one can imagine that the truth of the murder case is related to an old secret. ......

Sister is beautiful, virtuous, dignified and generous, which is a kind of primitive beauty unique to women in Shan Ye. She wears no makeup, no veil and plain clothes. She smiles and exudes the fragrance of morning dew and wild camellia. Without the dazzling packaging of urban women, she conquered many men in Shiliba Village by her beauty alone. Countless suitors poured in. Those who are not afraid to refuse will come home to propose marriage, and they are embarrassed to fight for it in private. They regard this village flower who can marry Lanting Village as a cause that spares no effort. Sister's feelings are tortuous and confusing. What she loves deeply and madly is the pain she has to endure in this life. No matter how many storms she encountered in her life, she never wavered in her adherence to discipline and ethics. She has always been accurate in her life and has never offended anyone. Even though they hate each other for getting her, she really owes only one man in her life.
