My Apocalyptic Fortress: Under the Iron Dome

In the Age of Rust, the nanomania engulfed civilization. Lin Feng, a former engineer, built the "Iron Dome", the last lone bastion in the overturned world. Others are struggling in the rust, but he can only hear the wail of metal; his creation AI "Crimson" is always using a blood-red dialog box to calmly calculate the probability of civilization's survival. "You are the 'one-thousandth' factor in the survival of civilization." But when metal rust stains appeared on the organic farms on which he relied for survival, and when predators' cannons exploded in the domes - Lin Feng understood that he was not only a guardian, but also the only "resonator" of this plague. Under the iron dome, sparks are rekindled; in despair, the truth is glimpsed.
