In 2847, humanity split into two worlds.
"Mirror City Area A" suspended 10,000 meters above the ground - a paradise for the elite, possesses all cutting-edge technologies such as virtual mirrors, quantum computing, and immortality of consciousness.
"Mirror City Area B" on the ground - a prison for 99% of the population, high technology is controlled, and people live an almost primitive life.
There is no physical passage between the two areas. The only connection is the "virtual mirror" - a digital world that stores the consciousness of the deceased.
The degaussing attack is coming.
The alien fleet of the Ring Council dropped a devastating electromagnetic pulse on the earth, and the world's high technology was reduced to zero overnight. The Sky City in Area A crashed, and the elites were forced to flee to the ground they once looked down upon.
Area B - the place that was ridiculed as "backward" - became mankind's last hope.
Lu Chenzhou, the engineer trapped in the virtual mirror, is the only person who knows the weaknesses of the Ring Council. But he also discovered the dark truth of Xu Jing: Area A has been using the consciousness of the dead in Area B as "sustainable computing power."
Jiang Lan, the leader of the resistance organization in Area B, needs Lu Chenzhou's knowledge to save humanity. But she couldn't forgive—he had been the architect of systems of oppression.
The alien fleet is approaching the city.
The fate of mankind hangs between a "betrayer" and a "rebel".
They must answer the same question:
When civilization faces extinction, does justice still have meaning?
