Lin Zhaozhao, the only daughter of General Dachu, accidentally traveled through time, resonated with the Soul-Shou Jade, and fell into the arms of Gu Chenzhou. He took her home because of the strange movement of the jade pendant, but he didn't know that the red marks on her wrists and the lines on the jade pendant were from the same origin, hiding a fate that spanned three hundred years.
She relied on her medical skills to save Gu's mother, break the rumors, and gain a foothold in modern times; he protected her thoroughly, from questioning to lovingly protecting her. When the ancient jade appeared and her memory recovered, she realized that she was the "Princess Zhaozhao" who was framed three hundred years ago, and that the Gu Chenzhou family was actually the "ancestors of the Gu family" who guarded the jade pendant.
The two work together to uncover Da Chu's conspiracy to destroy the country, fight against kidnapping by foreign forces and obstruction by their families, and confirm each other's feelings in a life-and-death crisis. When the two jade lovers came together and time and space became stable, she faced the choice of "returning to Da Chu to rehabilitate herself" or "staying with him in modern times", and finally chose to build a "double world undertaking" with him - Zhaozhaotang Traditional Chinese Medicine Clinic to connect the two worlds of medicine, and Gu's Cultural Tourism to promote the inheritance of Da Chu culture.
Five years later, Gu Chenzhou held her waist in the sunset and watched the mixed-race baby chasing butterflies. The jade pendant on the wrist glows with warm light, witnessing that this love that has spanned thousands of years will last forever in the daily life of fireworks.
—— "It turns out that the most precious thing is not the time travel itself, but meeting the person who is willing to live with you for the 'thousand years' into the 'rest of life'."
