[A reasoning investigation of a strong female medical concubine seeking power for her family and country]
Above the authority, a sharp knife hangs high.
She is a 21st century doctor with extraordinary talents and magic skills. She died in a car accident and became Chai Sang, the youngest daughter of the Jing'an Prince's Palace in Daye.
A relative of the royal family, the jewel of the family, but his family was destroyed due to a huge change.
From then on, "Ghost Yama" Sang Tong was born.
He holds life in one hand, asks about death in the other, helps the world as a doctor, and writes poems about bloody cases.
"You were born above the clouds, and you should open your eyes occasionally to see that thousands of miles away, there are people who have worked hard, and there are people who have died at the border."
"The butcher's knife in your hand cannot control the will of the people, and you cannot change right from wrong."
The broken souls of tung flowers, the bones on the riverside, the bloody shadows of ghost houses...
The clues are intertwined, and the lights of swords and shadows follow each other.
Under the cover-up of the truth for nine years, is it a loyal soul who has no regrets, or is he a beast in disguise and evil spirits running rampant?
When the thousand mountains pass and the wind and snow stop, she wants to walk alone in the world.
Someone held an umbrella and looked back, coming towards her, "What you want is what I want."
She thought that the two of them would end up on different paths, but she didn't expect that they could reach the same destination even though they took different paths.
