Academy City, Twenty-second District.
This was a very special district.
The district covered only four square kilometers, making it one of the smallest among all of Academy City's districts.
Yet it had been developed underground, creating a futuristic space that extended hundreds of meters below the surface.
There were no ordinary houses or buildings aboveground in this district, only row upon row of wind turbines.
Their spiral blades operated constantly, arranged in crisscrossing rows like the steel framework of high-rises. Vast numbers of spiral blades were set up in three-dimensional layers reaching the height of a thirty-story building, creating a truly spectacular sight.

There were even forests, using the hydroponic technology of agricultural buildings. Besides purifying the air, they played an important role in providing people with emotional support, ensuring the underground space did not feel too oppressive.

As the limousine drove into the passage leading to the underground streets of the Twenty-second District, the girls let out exclamations of wonder.
Unlike the orange lighting of ordinary tunnels, the underground passageways of the Twenty-second District glowed with a faint blue light.
Within the vast space, two
