In 2147, time has become the most expensive mineral in the neon city. Scavenger Lu Mi uses her pocket watch to erase the memories of patients suffering from chronosis every day until she discovers that all the deceased people exactly match her sealed childhood photos. When the mechanical nun Lin Ying appears on the black market with the same genetic code as hers, a conspiracy about the reincarnation of civilization that spans five thousand years comes to light - the "time skeleton" energy mined by humans is actually the cocoon shell of the ancient god Tartarus, and the memories of the destruction of the seven epochs are being awakened through the gear gene chain.
At the junction of Cyber City and the Cthulhu Abyss, Lu Mi was forced to face the truth: her pocket watch was the last shackles to suppress the ancient gods, and Lin Maya's cloned body held the key to restarting the world. When the first crack of the Gate of Time opens deep in the Arctic mines, the blade that tamperes with memory and the passage of time becomes humanity's last bet. There is no savior here, only a group of "Children of Time" struggling between mechanical wings and flesh and blood, using broken pocket watch gears to sound the last death knell of civilization for mankind.
