The terrain of the Heaven Camel Mountain was very special; there were two extremely tall peaks that from afar looked like the humps on a camel's back. Hence, it had been called the Heaven Camel Mountain.
In the Earth Emanations Domain, gravity was terrifyingly strong. The higher one went, the stronger it became. Hence, ordinary formidable martial artists were hard-pressed to fly up more than five million feet into the high skies. However, this Heaven Camel Mountain's peak was even higher than that; if an army wanted to attack the peak, most people could only crawl their way up. This was an excellent place to defend against an assault.
