I was born with a unique ability to smell good and bad in people - good people have a refreshing fragrance around them, while bad people have a disgusting stench. Everyone said that Emperor Beichen was cruel and murderous, a ruthless Shura, but that day when I bumped into him from a distance, what came to my nose was a scent of bitterness and sweetness, like the old white tea on the edge of the cliff after snow. Unexpectedly, the emperor took me back to the palace, and ordered me to stand by the side of the palace every day, smelling the ministers and concubines who came to see him, and telling him one by one who was fragrant and who was smelly.
