She wanted to bid farewell to the past in a hurry, but because of a blood-stained suicide note and wandering cries late at night, she was involved in a bloody mystery that spanned three generations. Every time a page of truth is revealed, a dead soul whispers to her; every step closer to the core secret, the loved ones around her become more suspicious.

And the mysterious return of her former childhood sweetheart Shen Yanzhou is not only her only fulcrum of trust, but also the weakness that she dare not touch.

Not only did she avenge the wrongful death, but she also recast herself in the ashes - a dark heroine's revenge epic about female awakening, family betrayal and soul redemption came to a shocking conclusion.
