The Age of the Giant Moon

The ancient age of cultivation was a real era of Earth-Moon engineering. Its fall was not the result of the gods vanishing, but of a civilization being wiped out after lighting a torch in the dark forest. After dreaming of Baiyujing three times, discovering a geometric mark on the back of his neck, and finding confirmation in the Shan Hai Jing, he was contacted by a signal from another era. A colossal, artificial moon hangs in the sky. Its tidal force reduces Earth's gravity by a third and gathers oxygen into an "oxygen dome" over the hemisphere facing the moon. This gives rise to a world of cultivation where people can fly on swords, while ordinary people on the far side of the moon remain short, oxygen-starved, and trapped in darkness. The mountaintop city of "Baiyujing" and the far side's endless silence are the two halves of the same unfinished work of cosmic engineering. The colossal moon is more than a shelter. It is a torch lit by the ancestors: it illuminates the path to survival, but also exposes the civilization itself, drawing eyes from the depths of the dark forest. The straight, slowly lengthening dark line on the moon's surface is no crack. It is the approach of a purge with no one left to hear it.
