The story begins with the bride marrying off her daughter, and the woman, at the age of one hundred,

"Though the sun sets late, its afterglow still fills the sky." "Ninety years old is the age for adventure." "This old man, in a moment of youthful exuberance..." A ninety-year-old man, Chang Shou, was struck by lightning while sheltering from the rain under a tree. His granddaughter, to save him, agreed to marry the Dragon King. Fortune and misfortune are intertwined, gain and loss are inseparable. After Chang Shou's miraculous recovery, he broke free from the mystery of his birth and realized his identity as a transmigrator. To support his granddaughter and for his own immortal path, ensuring his journey wasn't in vain, he requested basic spells and basic qi-cultivation techniques from the Dragon Palace. He knew his own situation. Although Chang Shou awakened his innate wisdom, he remained clear-headed. He wasn't complacent about being a transmigrator, nor arrogant or unrealistic. He understood that he was essentially still just an ordinary old man. Knowing his lifespan was limited, he didn't strive to become a celestial immortal, a god, or an earth immortal. He only hovered between the realms of ghost immortals and human immortals, with clear goals and a profound understanding. Later, Sun Wukong came to visit, and the two of them joined hands to cross thousands of mountains and rivers, traveling together to seek the Dao at Fangcun Mountain, thus beginning their respective legendary paths... This is the story of an ordinary person cultivating into an ordinary immortal.
