The last time in the Heavenly Prison World, suppressing the Dark Domain lifeforms, Lu Changsheng, Liu Qing, and others managed to gain a large amount of Contribution Points.
"The Heavenly Prison is actually a place to suppress Dark Domain lifeforms, but the reason it's suppression and not extermination is because it's simply not possible."
"In the deepest part of the Heavenly Prison are two Dark Domain lifeforms being suppressed. Back then, the Heavenly Light Saint Sect suffered heavy casualties just to barely suppress them, but that's all they could do."
"But over time, there are always leaks, and occasionally the Heavenly Prison fractures, allowing some Dark Domain lifeforms to escape. Although those two Dark Domain lifeforms did not escape last time, it still required five of our Chaos lifeforms from the Heavenly Light Saint Sect to constantly suppress them in the Heavenly Prison."
