The base of the Pan Gu bell was Buzhou Mountain, which was transformed from Saint Pan Gu's spine. It was the core of Pan Gu world, which maintained a balance of the world and stabilized the great Dao of nature.
The sun and the stars hung above Buzhou Mountain, and earth meridians were buried underneath it. All Pan Gu world creatures lived around it, and all natural laws were centered on it. Every intelligent living being had left its smell on Buzhou Mountain, like flying birds left their reflections on the water surface and walking birds left lines of footprints on a snowfield; every natural law had marked Buzhou Mountain.
Nourished by the world for countless years, even the finest grain of dust from Buzhou Mountain had a strong sense of the great Dao of Pan Gu world.
