Long Qing, a top modern science and technology doctor, was accidentally electrocuted while studying the ancient jade dragon. He carried modern knowledge and the jade dragon soul through the Zhenguan period of the Tang Dynasty. When he first entered the Tang Dynasty, he mistakenly entered a hot spring and bumped into a young girl Qing Yu'er bathing. She was regarded as a prostitute and formed an indissoluble bond with her. From the initial misunderstandings, boredom, and tit-for-tat confrontation, to the numerous setbacks such as survival crises, court intrigues, border wars, technological innovations, and cultural collisions, Long Qing relied on his knowledge beyond the times, his calm mind, and his tenacity to make a living in the Tang Dynasty. From an unknown refugee, he grew into a legendary figure who influenced the Zhenguan Dynasty. And Qing Yu'er gradually saw Long Qing's talent, responsibility and gentleness from the initial disdain and disgust. In the intertwined times of troubled times and prosperous times, the two worked side by side to overcome all difficulties, and finally broke the identity barrier and got married, composing a love that spans time and space.
