Flurries of snow drifted down as a blue-black winged bird spread its wings, silently and rapidly weaving through the snowy world, the ground below desolate with only a mirror-like river meandering through.
The bird dove down and followed the river upwards, occasionally stretching its wings without losing speed. It wasn't an ordinary bird but a transcendent animal.
Beyond the vast gobi-like land, the silhouette of a budding city finally emerged through the snowstorm, with unfinished skyscrapers among which floated autonomous units, diligently working in the snowy sky even beyond regular hours.
Apart from these AI-controlled autonomous units, workers wearing orange helmets and conspicuous reflective gear could be seen among the chaotic streets and buildings, some assisting the autonomous units with complex details, others conducting inspections and giving directions.
