Fifteen years after the Cataclysm, the wasteland was overturned, corpses were rampant, and humans were struggling to survive in the remaining strongholds.
Shen Chiyan, the most ruthless top executor in the organization, codenamed Zero, is decisive in killing, but has lost his memory for three years. After a siege by a zombie wave, she was forced into an absolute restricted area that had been sealed for three years. Deep in the underground ruins, she personally awakened Su Qingmian, who had been sleeping in a dormant cabin for three years.
She is Gentle Moonlight from three years ago, the daughter of a researcher. Her memory is stuck on the night before the explosion. She knows nothing about the apocalypse. At first sight, she regards Shen Chiyan, who is covered in blood, as the only salvation in a desperate situation.
The cold, lonely person who lives alone makes an exception for others for the first time. She shared the only food she had and stayed at her bedside all night, using her flesh and blood to support her in front of the fangs of zombies and predators. In the desolation of the last days, darkness and light embrace each other, coldness and tenderness coexist, and they become the only bond between each other.
But under the sweetness, doubts grew wildly. The memory erasure scar on the back of her neck, the severe stress in the laboratory, her father's bloody notes, and the sealed past, all clues point to the cruel truth - the lover she regarded as her life was the executor who killed her father.
Once trust collapses, love and hate surge and pull. She hated her to the core, but couldn't see that she was covered in bruises to protect her; she was wrapped in hatred, but she was willing to betray the organization and fight one against a hundred. Even if her memory was completely lost, the instinct to protect her was already engraved in her bones and blood.
The manipulated chess pieces, the concealed conspiracy, when the truth is completely revealed, on the ruins, they will finally hold each other's hands, and find their own sleep and rebirth in the apocalyptic wilderness.
Purpose: Nothing is an exception
