Qin Hao, a modern business elite, traveled to the Xuanyuan Dynasty after a car accident and coexisted with a frail boy of the same name. The original owner was predicted to die at an early age when he was 13 years old, and the two reached an agreement: to revitalize the declining Qin family jewelry store by integrating modern business thinking with the original owner's amazing arithmetic talent. While operating in Xingcheng, Qin Hao met the prince Xuanyuan Ke who visited privately incognito. He repeatedly resolved crises with his outstanding business skills and gradually gained the prince's favor. When the prince revealed his identity and invited him to the capital, the original owner's soul had reached its limit and disappeared after witnessing the rise of the family. Qin Hao became the number one imperial merchant in Yaodu, but unexpectedly discovered a shocking secret hidden by the dynasty - his mother was actually a scientist at the Seventh Institute of Atlantis, advocating the integration of life and machinery. This discovery propels him on an extraordinary journey beyond commerce, to uncover the truth about the intertwining of two civilizations.
