The beautiful concubine of the prime minister's palace was once forced to marry the rumored moody deposed king.
She thought it was a dead end, but she signed the contract with a smile: not to interfere with each other, and each to get what they need.
No one knows that on the surface she is a humble concubine, but secretly she is a mysterious divination master who can discern the secrets of heaven.
During the day, she pretends to be stupid to survive, but at night, she stirs up troubles with her unparalleled calculations.
Until one day, the cold-faced King of Hell blocked her in a corner and said, "Princess, are you wrong about this hexagram?"
She looked at the "deposed king" who suddenly came to life and the shocked civil and military officials of the dynasty, and blinked innocently: "... Is it too late for a divorce now?"
