She has been killed six times. Always by the same hands. Always by the men fated to love her. Across six lifetimes and five shattered worlds, she dies the same death — not by strangers, not by enemies, but by the one soul the universe itself bound to hers. The Emotionless Emperor kills her on palace marble. The Strongest Under Heaven beheads her at a cliff's edge. The Star Emperor pierces her with starlight in a collapsing galaxy. The King of the Dead strangles her while weeping. The Dragon Monarch crushes her in hands that were meant to hold her. And in her sixth life, broken beyond grief, she simply stops breathing on her own. She wakes before the God of Destiny — and learns the truth that destroyed everything. The God grants her one final life. One world where all five powers exist. One chance to choose differently. She enters her seventh life with no intention of choosing anything — except survival. She is eighteen, razor-sharp, and carrying six lifetimes of grief behind serene eyes. When The Iron Sovereign, The Heavenly Saint, The Celestial Emperor, The Eclipse Pontiff, and The Crimson Dragon King all look at her across the same room for the first time, she already knows their faces from her nightmares. She doesn't run. She plans. But the universe has its own agenda. And the five men who murdered her across time are starting to remember. The question was never whether they would love her again. The question is whether love — and the people carrying it — can survive what it cost before.
