Lamp of Tied Bones

Born with a yin fate, Sang Wanning mistakes her savior, Shen Yuchen, for his elder brother, Shen Yuji, and happily prepares to marry him, unaware that he died in battle long ago. By a twist of fate, she weds Shen Yuchen instead, whose memories of saving her have been erased. Now, he sees her only as the blood sacrifice needed to break the Shen family's century-old curse and resurrect his dead brother.
