Alternate Three Kingdoms setting. Not entirely historical; an imaginative story.
After transmigrating, she finds herself amid the fires of war at the end of the Eastern Han dynasty, just as Cao Mengde is still young and beginning to show his brilliance.
Armed with a thousand years of knowledge from the future, she accompanies him onto the stage of history, identifying worthy talents and devising strategies to help him establish himself in a turbulent age and gradually build the foundations of Wei. She believes she is an outsider defying fate, the most trusted confidante at his side. But as they spend day after day together, she falls into a love she should never have felt and a trap she should never have entered.
Yet the course of history never shifts easily. She gives everything she has, but in the end, she cannot change what is destined. Only when the truth is revealed does she realize that, from beginning to end, she was the very person he had the most reason to guard against.
They supported each other for half a lifetime, and she poured all her ingenuity into him, but in the end it was all just a calamity written in fate. When the Bronze Sparrow Terrace rises and his ambitions are fulfilled, she gazes at his back as he stands high above all others and finally chooses to walk away. She buries their love, spanning two lifetimes, in the smoke and turmoil of the Three Kingdoms, leaving behind only a lifetime of regret to scatter across the world.
