A wedding becomes a tomb. Sixty years of waiting transforms grief into something sharper than revenge, something that rewrites who you are. Xihe is what happens when you survive long enough to become the thing that would have saved you, and the show makes you feel every year of that cost.

Yun Wangshu's wedding day turns to horror when a brutal conspiracy wipes out her entire clan, and the betrayal comes from someone she loved. After barely escaping, she makes a desperate pact with the Silent Court. Sixty years later she returns, reborn as the merciless Xihe. She has given up the pursuit of immortality and now walks the path of a killing deity, set on making those who took everything from her pay. Across 26 episodes, the story blends action, adventure and fantasy around its tragic heroine's quest for vengeance.
