Lu Li learned many secrets from Leng Wuxin and he had formed some ideas of his own even though some of them seemed unimaginably queer.
First of all, the Purgatory of Primordial Chaos was a place of wonders. It had 10 levels of Prisons of Fire, Wood, Earth, Water, Gold, Ice, Wind, Darkness, Soul, and Thunder. He was told that after going through the 10th level he would be able to ascend to the heavens and become an immortal, a god.
Many strange creatures were nurtured in the Purgatory of Primordial Chaos. They weren't highly intelligent but they came with strengths. If people of Heaven Reverse Universe learned about the Purgatory of Primordial Chaos, there would be a huge reaction.
It seemed like the Purgatory of Primordial Chaos was connected to many universes.
