The overworked Li You died suddenly on the job. When he awoke, he found himself reincarnated as the Tang Dynasty's eighteenth prince.
The good news: He had a noble status and wanted for nothing.
The bad news: His mother was dead, his father had no time for him, and no one in the palace even remembered he existed.
Worse still, it was the fourth year of Yonghui. Wu Zetian had only recently entered the palace, while Zhangsun Wuji and the emperor were locked in a fierce power struggle. A storm was about to break. As a modern man who just wanted to slack off and get by, Li You decided to keep a low profile and stay out of trouble...
Then he accidentally complained at a palace banquet that "mutton smells so gamey," and Wu Zetian overheard him.
Then he accidentally invented soap at the Qingliu Bureau, and it became a sensation in the harem.
Then he accidentally improved some farming tools, and caught the emperor's attention.
Then he accidentally got dragged into the struggle to depose the prince and enthrone Wu, only to realize he'd already taken his seat at the table...
