Before their departure, Ling Xiao had given the ten Demon Hunters designated to enter the Illusory Paradise detailed information about their possible future encounters inside.
Generally speaking, the Illusory Paradise would be rather peaceful and they would just encounter the magical beasts guarding the spiritual stoves they’d find. However, some special circumstances could also appear. For instance, if the concentration of killing intent was too intense in the Illusory Paradise, it could very possibly cause changes to the surroundings.
The Illusory Paradise would produce approximately twenty spiritual stoves every single time, but before these spiritual stoves were truly absorbed, they would remain masterless objects. And that was to say, even if one had temporarily absorbed a spiritual stove, in case he died, the spiritual stove would regain its freedom.
