At the bottom of the sinkhole in the Western Wilderness lived many serfs who had served the monks in the Xuankong Temple and maintained the society. In Haotian's eyes, all the humans living in the world were serfs, like ants who lived boring lives without complaint.
Over the span of many centuries and millennia, a few very distinguished ants among the crowd would, out of enigmatic reasons, decide to strip their gazes from the rotten leaves and, just for once, gaze up at the crystal blue sky.
Since that time they saw the sky, their lives had changed. Some of them saw hope; some were angry at the unreachable sky; some were afraid because of what they had discovered, so they knelt down on the ground, being thankful for the gift from the sky.
No matter how they ended up, these ants were no longer ordinary ants. In a sense, they had evolved and they learned how to fly.
