She was once the greatest physician under heaven, having saved countless refugees, soldiers, and common folk. But she trusted the cold-hearted Crown Prince and the scheming Second Female Lead, who tortured her to death on the charge of being an "enchantress who bewitched the ruler" and practicing "heretical medicine."
After her death, the Underworld fell into chaos! The lives she had saved in her lifetime far exceeded the number allotted by Heaven, and she had single-handedly altered the King of Hell's Book of Life and Death beyond recognition. Furious, the stone-faced King of Hell came to claim her himself and forced her to take over his position, so she could experience the misery of having her work thrown into disarray and her life taken out of her hands by someone "defying Heaven's will."
In my past life, I commanded the art of healing in the mortal world and saved your life;
In this life, I command life and death in the Underworld, and decide your fortune and misfortune.
You owe me. I'll make you repay me, life after life.
