In the "Calculation City" fully covered by Oneworld Group's sophisticated data network, every breath, every consumption, and even every heartbeat is converted into predictable numbers. Su Guang, one of the founders of the data empire in the past, is now hiding in the market, but he is forced to be involved in a disappearance case with wide implications. The missing person does not simply disappear, but is completely "erased" from the data world, as if he had never existed. Behind this is the invisible manipulation of society by the Huanyu Group using its "Sky Eye" system. It is the intricate entanglement of interests between high-level politicians and criminal gangs, and it is the ultimate challenge to legal justice and human free will. Tracer must shuttle between glamorous business empires, shadowy criminal networks and decadent political whirlpools. With his unique data traceability ability, he can uncover the carefully woven lies, pursue the "traces of light" that have been almost completely erased, and recover the truth and justice swallowed up by the data.
