After the social animal Bu Yinyin died in a car accident, she refused to be reincarnated. She was determined to take the exam for civil servants in the underworld, making soup and eating CP - but because she didn't score enough, she was transferred to be a judge under the King of Hell!
His immediate superior, Nangong Yebai, appears to be a cold-faced and venomous workaholic, but in reality he is cold on the outside and hot on the inside, carrying the burden of three hundred years of unjust cases. The two were forced to travel through time together to solve ten bloody unsolved cases that spanned thousands of years: the bloody wedding dress, the elixir of longevity, twins in bronze mirrors, the general's lonely tomb, and the burning heart...
Bu Yinyin was writing a transfer application while crying to save all sentient beings; Nangong Yebai was punishing her to copy books while silently telling her the truth.
From the narrow road between enemies to the secret love, until the last case, the crime of Nangong Yebai's previous life was revealed——
"If I lose my soul, I will still keep Meng Po Gang for you."
"Then I'll be destroyed with you."
The underworld never has a holiday, and love never ends. After the ten cases were over, she withdrew her transfer application and became his permanent "chief judge".
