When Xie Liangchen avenged her brother's death, she believed her fate was sealed—that all obligations would dissolve with her final breath. Yet as lightning split the sky, she awakened as a fourteen-year-old girl, her second chance at life shimmering before her. Marquis Xuanwei stood beside her, still years away from the formidable power and commanding presence that once terrified kingdoms. Before Xie Liangchen could disappear into the shadows of ignorance, Song Xian's piercing gaze found her. "Running from your promise?" His voice cut through the air like steel. "You swore to repay my kindness across lifetimes—as ox, as horse, as anything fate demanded." The words hung suspended between them. Song Xian, a man on the edge of absolute dominion, had been dragged backward through time to his nineteen-year-old self by Xie Liangchen's impossible knowledge. Her reappearance raised a question that burned like wildfire: Is she honoring an ancient debt or crafting the perfect revenge? Two souls reborn with memories intact forge an unstoppable partnership, where devotion knows no bounds and ambition reshapes destiny. In this world of power and peril, they rise together—neither willing to face the future alone.
