Though the sun sets late, its afterglow still paints the sky, and ninety is merely the age for a new adventure. When a freak lightning strike leaves ninety-year-old Chang Shou at death's door, his devoted granddaughter makes the ultimate sacrifice, agreeing to marry the Dragon King to save his life. Miraculously surviving the ordeal, Chang Shou awakens not only to full recovery, but to the long-dormant memories of his past life as a transmigrator.

Armed with wisdom, pragmatism, and time ticking relentlessly against him, this centenarian begins a journey where wisdom rivals raw power, proving it is never too late to defy the heavens.
