The entire Upper Qing Starry Domain doesn't have a sun or moon, but the Purple Mist City still distinguishes between day and night.
All this is because of the Yan Light Array spread across the sky above the Purple Mist City.
When this formation emits a dazzling white light, it's daytime; when the white light fades and is replaced by a soft glow, it's night.
This form of day-night transformation is not uncommon in the Multiverse.
Because not every planet can be illuminated by the sun and moon like Earth.
Although the formation can provide constant illumination, and the absence of day and night changes doesn't affect these cultivators much.
But due to the nature of the Human Clan, people habitually adjust the formation to create night and day.
At this moment, as Xue An and others had just settled in, the lights outside already shone brightly, and the sounds of noise and laughter came faintly from afar.
