When the gentle corpse exorcist was planning a conspiracy to subvert the three realms, the cold-faced Prince of Hell made many exceptions for him. When one case after another was unraveled and the truth was revealed, everything he thought was going smoothly was all his wishful thinking with his acquiescence. The fate of the two is closely intertwined. While testing each other and fighting side by side, they uncovered the truth and became each other's only light.
Shen Qing'an, the owner of a paper-making shop with a gentle appearance, was listed as a suspect by Lu Yan, the leader of the underworld, and was forced to "cooperate" in the investigation due to a series of strange murders related to the "Eternal Life Pavilion". The two were repeatedly attacked by evil spirits in funeral parlors, theaters, hospital morgues and other dangerous places, and gradually discovered that all the cases pointed to a crack connecting the "Return to Ruins" guarded by the Shen family for generations, and a family bronze mirror as the key.
Shen Qing'an is trapped in the whirlpool of family contracts, the truth about bloodline, and obsession with revenge, while Lu Yan is burdened by the pressure of the underworld order and internal rebellion.
On the night when the gate of hell opened in the middle of July, in the ancestral land of the Shen family, the two faced the will to return to the ruins, the betrayal of the judge, and the conspiracy of the Changsheng Pavilion. They were forced to rewrite the ancient contract, and Shen Qing'an also became the "supervisor" of the replacement of the old and new contracts. However, the crisis is not over, new mysteries and invitations follow one after another...
Purpose: Amidst the bizarre mysteries and bloodline fate, explore how individuals stick to their hearts, make choices, and find the possibility of trust and redemption while being caught between established destiny and powerful rules.
