The document contains Yang Jun's research on the hidden space near Cangkuo Mountain. After making many deductions, Yang Jun concluded that the hidden space is actually a prison.
Inside the prison, there is an incredibly powerful being imprisoned, at least at the True God Level.
The exterior of the prison is an Absolute Sky Array, isolating Heaven and Earth. This Great Array was created by Yang Jun's ancestor, Yang Yuan.
Yang Yuan used the Absolute Sky Array to imprison an incredibly powerful being within it, utilizing the hidden space.
Yang Jun explained, "The ancestor set up this Array to isolate Heaven and Earth and cut off the space in order to imprison the incredibly powerful being."
"Brother Xiao, this Array cannot be opened, otherwise, if the being emerges, it will surely cause great trouble."
"I understand."
Xiao Mu nodded, "The descendants of the Kuang Clan have told me that Kuang Shenfeng once served as a prison guard; the prison he guarded must be this one."
