Yun Xi is thrust into the body of a miserable young woman from a wealthy family. Her biological father shows her no affection, her stepmother plots against her, and the fake heiress Weiwei shines brightly, while she is nothing but a stepping stone meant to make the heroine look good.
But no one knows that the body is now home to a wisp of the returning soul of an ancient mystic warrior and guardian of the Star Gate. When an ancient jade star chart lights up in her palm, her dormant memories awaken. She is no cannon fodder, but the only key to the Star Gate that stands between the mortal world and "Oblivion."
Huo Lin, the cold and devoted man who fell from the sky, turns out to be the guardian bound to her in her past life by a life-sharing pact. He has protected her through seven cycles of reincarnation and a thousand years of loneliness. The brand on his chest was proof that he had taken her tribulations upon himself. Then Yun Xi discovers that someone secretly layered a "Soul-Locking Seal" beneath the brand. The culprit is Xuan Xuzi, the senior brother who betrayed her in her past life and is now president of the Mystic Arts Association. She was never the only one who was manipulated in her previous life.
To remove Huo Lin's seal and reseal the Star Gate as it begins to awaken, Yun Xi sets out to collect three primal treasures: the clan's ancestral marrow jade, the dragon-sealing spike that anchors the dragon veins, and the military's secret stash of Star Tears. Along the way, she crushes the fake heiress's schemes, exposes the Mystic Arts Association's plot, rallies a hundred thousand people through livestreams, establishes "Star Rampart," an organization to protect the world, and draws the nation's forces into the struggle.
The thousand-year guardian's return is a journey of mutual salvation. This time, she will protect him, and together they will close that gate for good.
In the modern world, the heroine quietly (and not so quietly) regains her powers while resolving her own troubles, including survival and the Yun family's feuds. She uses her supernatural abilities, mysticism and martial prowess, to face-slap and punish villains while building up faith, merit, and wealth. Along the way, she gets swept into a romance with the hero, and ultimately achieves a satisfying revenge, reveals the truth about the world, and reaches a happy ending.
