"Death Line" revolves around the Jiangcheng subway system. The shadow of the 307 train accident in 1998 has never dissipated. When reporter Lin Mo was investigating a serial death case, he discovered that the deceased had strange gear marks on them, and the clues pointed directly to the dusty old case.
The gear prints in the newspaper archives, the concrete secrets in Office 307, the blood vine traps in the abandoned mine tunnels... Everywhere hides fragments of the "gear system" - this is a horrific experiment driven by human body modification and emotional energy. The accident in 1998 is just the tip of the iceberg in which the system is out of control.
Zhou Ming's encrypted folder, Zhong Ming's crazy manuscript, Xiaoya's brother's disappearance... The fate of the seven experimental subjects is tightly interlocked with the gears. When Lin Mo's team got closer to the truth step by step, and modified people, clones, and mirror phantoms came one after another, they discovered that the so-called "system" had already parasitized the city's bloodline, and everyone involved was a tooth on the gear that could crack at any time.
In the strangulation of human nature and machinery, is family love the only key, or is it the fuel that accelerates destruction? Those innocent souls embedded in the railway tracks, the reflections behind the glass, and the "new human beings" in embryos will eventually usher in the ending of the gears stopping when the truth is revealed-either redemption, or death together.
