She is a hospice physician at a top private hospital, and the light touch of her fingertips is the last warmth of the dying; she is also the frightened "Shura" in the underground world. Between the flip of the scalpel, the criminals cannot escape the judgment.
Su Qingyuan is a contradictory person who combines extreme good and extreme evil. During the day, she sang lullabies to dying children in the ward and paid the sky-high medical bills out of her own pocket; at night, she used the most precise surgical techniques in the basement to make the abuser "experience" ten times the pain of the victim.
"I save those who want to live and kill those who deserve to die." This is not a split, but a survival rule that she has practiced throughout her life - after seeing too much innocent blood, she understands that kindness to the devil is a betrayal of kindness. When the daughter of her adopted enemy calls out "Mom" for the first time, when her first love who sticks to the law points a gun at her chest, when pure evil mocks her as "just a butcher wearing a fig leaf", will her steps on the blade of good and evil remain as firm as ever?
This is a long epic about redemption and judgment, and it is also a lonely journey of a woman guarding the last glimmer of light in the most cruel way. She is a saint and a Shura; a redeemer and a prisoner bearing eternal sin.
