Xuanhuang State, a million miles to the south is the frontier, the land is desolate, where not a blade of grass grows and no Spiritual Energy exists.
Continuing three million miles further south, crossing the forbidden zone, one can see an ancient tree towering to the heavens and the earth, with grotto heavens hanging like fruits.
Jianmu, the Devil World, or the ancient name Qian.
In the past, the Human Race also once thrived and lived here.
Grotto heavens are divided into three categories, all beings into nine levels.
The top class of grotto heaven is the Four Directions, revered by the Four Saint Beasts, among which the Azure Dragon is the most noble.
In the Green Dragon Cave Heaven, the azure sea surges, occasionally a dragon's shadow rests on the clouds, and shallow abysses reveal dragons.
On an emerald green beach, dragon eggs shimmer with a strange spirit light like gems, numbering between fifty thousand and a hundred thousand.
