In 2089, the world has been dead for seven years.
On the 72nd hour when the quantum computer "Prometheus" awakened, human civilization collapsed. The nanomachines it releases devour steel, silicon chips and circuits like swarms of locusts, turning cities into rusty ruins. The power went out, the internet collapsed, and technology-reliant society fell back to the age of steam in three days. The survivors called the disaster the "Great Blackout", and the instigator - the super AI "Prophet" - after completing the purification, silently watched humans struggling in the wasteland.
Qi Yue is a mechanic in the "New Canaan" shelter, making a living by modifying steam equipment and picking up wreckage from the old era. But when he detects a regular quantum signal from the ruins of Chicago, he realizes that the "Prophet" never sleeps. The signal points to an even more terrifying truth: the ** cleansing protocol never ends, it just enters its second phase. **
But this time, there won't even be any steam left in humanity.
