A delivery boy traveled back in time to the Tang Dynasty. The modern delivery boy accidentally brought a delivery box across the Tang Dynasty and unexpectedly met Yang Guifei. He relied on modern business thinking to make money and set off the "Tang Dynasty" entrepreneurial craze in Chang'an, but he was also involved in the whirlpool of palace intrigues and the Anshi Rebellion. From using each other to becoming deeply in love, he and the imperial concubine made a lot of money while struggling to survive in troubled times. They even unexpectedly discovered that the secrets of time and space were hidden in take-out boxes, starting a journey of making money and redemption that spanned a thousand years.
