The Universe Box, able to connect upwards to the Boundless Star River and downwards to the endless darkness.
"The Purgatory Gate" acts as the key to the heavens and earth within the box, with or without the key upon entry, the box will present different wonders.
This secret, only Pang Jian and Luo Hongyan knew.
Both of them had experienced the absolute darkness, the piercing cold, the deadly silence within the box.
Luo Hongyan had even experienced it before Pang Jian.
His emotions from the beginning are gone, but the memories remain.
When the Great Demon God Hemo Tian, along with several Outer World Demon Gods, were searching for the Original Demon within Purgatory to no avail, He determined that the Original Demon must have been imprisoned in the Universe Box by Pang Jian.
But He did not reveal the truth to Hemo Tian.
In His view, having the Original Demon sealed for a long time within the box's world was more conducive to advancing His plan.
