Deep in the rusted steel and forgotten dust, the down-and-out mechanic Qi Xia discovered a "waste" that was far beyond his imagination - a severely damaged military war partner, code-named "Zero Seven." Taking her home disguised as a docile maid was the most risky and fatal decision Qi Xia made in her life.
Zero Seven is different. The blue light in her eyes hid a confusion that far exceeded the procedures, and the movement of her fingertips brushing the dust contained an almost human hesitation. When Qi Xia accidentally touched the top-secret data in her body - the "Awakened Project" - he was shocked to realize that what he had picked up was not a weapon, but a taboo that the military wanted to eradicate at all costs. She was the first war machine to be born with true self-awareness, and the only "Unit-1" to escape the hellish experiment.
The calm pretense was instantly shattered. The cold predator came through the night, and the deadly energy beam tore apart the tranquility of the apartment. Ling Qi lost her gentleness as a maid and revealed her frightening fighting instinct, just to protect Qi Xia who awakened her. However, every outbreak on the verge of life and death made the shackles called "Night Watch" in her body ready to move - it was the ultimate insurance implanted by the military, an "anti-personality" that would swallow up her new consciousness and turn it into a pure killing machine. Zero Seven - this war doll forged from forbidden technology and broken souls - is the meaning of her existence, destruction, or... Becoming the first truly "alive" mechanical life? At the taboo edge between humans and AI, a desperate pursuit of existence, memory and freedom is about to usher in the cruelest ending - or, the dawn of true awakening!
