A strange case recently occurred in the capital. Several officials involved in the "Su Family Unjust Case" died laughing in their dreams one after another. Before their deaths, a strange orchid fragrance filled the room.
The court was helpless, and the commander of the Jinyi Guards, Rong Jingshen, was ordered to investigate. At this time, a new "Jiu Wantang" incense shop opened in the capital. The female shopkeeper Su Wansi cured the eldest princess's chronic illness with a furnace of "soul-inducing incense" and became famous. Rong Jingshen was suspicious of Su Wansi and came to test her.
