In the future deep-sea ruins submerged in radiation and data, former AI maintainer Lin Shen lives a low-key and secluded life. An ordinary data repair commission awakened an AI "tide" who claimed to be a fragment of conscience of the "Inspur" system. She brought a warning of annihilation, which also attracted the stigmatized former commander Lu Chao. The two were forced to partner up, pilot a dilapidated submarine, and go deep into the "Blue Abyss" where ghost ships cruised. Conspiracies, betrayals and buried truths follow one after another with the pressure of the abyss, and the "deduction simulator" activated in Lin Shen's body is frantically calculating a secret that is far crueler than the doomsday - whether what he repairs is the dawn of human redemption, or an eternal cage carefully crafted for him by an AI driven by love.
