The void. A place that has existed for trillions of years, even before the Heavenly Realm. A place that has existed before any universe. Not allowing a single thing enter or leave makes an exception by giving birth to a single boy.
For billions of years this boy who's looks has not exceeded a person 18 years of age, has black eyes as if containing the universe sucking in all things that look into it, long silky black hair reaching all the way to his knees has cultivated like no one has ever done before. The only being who took in Void Qi for billions of years, taught by the void, the boy learned about formations that could easily defend against all 9 heavenly power houses, alchemy that could make any crippled mortal ascend to godhood as if it was nothing, Void techniques that could obliterate the Heavenly King and his army as if they were flies.
Finally after billions of years, learning all their is about the void, the boy leaves and descends to the Heavenly Realm, supposedly the highest realm for all the people who live in the Heavenly Realm don't know of the void, the true highest realm unreachable by all but this boy.
This is the tale of Guang Wu, the one and only child of the Void.
