Sullivan Su, a modern man stranded in the Tang Dynasty, only wanted to laze around his estate. Yet, his skills—from hot pot to advanced farming—caught the attention of Empress Changsun. Forced into a pact with “grain merchant” Emperor Lionel, he secretly reformed the economy and defended the empire, thwarting invasions and plagues. After bankrupting a noble clan and saving a princess with a vaccine, Lionel’s true identity was revealed. Offered a royal title, Sullivan’s plea was simple: “Let me retire!” Little did he know, he was already the unseen guardian of the Tang Dynasty’s golden age.
