In the cold and cruel city, the humble courier Gao Da enjoys the indifference of the world and struggles to survive. An unexpected act of saving lives led him to encounter the "Dream-Wandering Judge" of the previous generation when he was dying, and he was forcibly selected to inherit the mantle of judge.
From then on, his life was divided into two completely different sides: during the day, he was still the courier boy who ran around in the reinforced concrete jungle and saw the warmth and warmth of people; at night, he transformed into a lonely judge of the underworld, judging the souls of the dead in strange dreams, controlling reincarnation, and maintaining the order of yin and yang.
As a judge, he gained the mysterious power to see into the yin and yang, look back on the past, and seduce souls, but he was also burdened with the cruel iron law of "cutting off love and never falling in love, keeping virginity forever." Facing a secret love that was once out of reach, and facing all kinds of temptations and entanglements in the city, how will he struggle and choose between the fate of a judge and the emotions of mortals?
What kind of truth and conspiracy are hidden behind the bizarre death cases and the resentful souls? Every trial is a torture of human nature, and it is also a ladder for him to accumulate merit and improve his rank as a judge. As his power continues to escalate, he will gradually uncover the deep secrets behind the chaos of the underworld and the vacant position of judge, as well as the mystery of his own unique fate of being "alone" but "full of merit".
Between the cold city and the dark underworld, Gao Daxi's journey as a judge is destined to be full of reversals, dangers, adventures and tests of human nature. Can he stick to his heart, break the shackles of fate, and finally find his own way?
