Xiao Jingming, the most idle prince of the Great Xuan dynasty, has one ambition in life: to eat, drink, and wait for death.
A bad friend tricks him into going to the Drunken Immortal Tower, where he stumbles into a courtesan's murder case.
The room is full of powerful nobles crowding around the newly appointed top scholar. Only a young constable in the corner is examining the body.
Just as he tries to slip away, a petite figure blocks his path. "Your Highness, stop! There's blood from the victim on your sleeve."
Xiao Jingming looks at his thousand-tael brocade sleeve. "...Can I wash it off?"
Lin Xiaoxiao pulls out her notebook. "No, it's evidence. Please cooperate with the investigation, Your Highness."
That night, a second courtesan is found dead. The powder in her sleeve matches the bloodstains on Xiao Jingming's cuff.
He pinches the powder and sighs. "Are my carefree days really over for good?"
Lin Xiaoxiao rises onto her toes and pats his shoulder. "Don't worry! Once I become the greatest woman constable, I'll clear your name!"
