On the 1st floor, Cultivation Manual Area, Arcana Library:
While his wives and children were in the entertainment section, Maximus came here to choose a cultivation technique.
In the Arcana library, all knowledge ranges from tier 0 to tier 6 are free, no matter the identity.
This allowed the widespread dissemination of knowledge across the entire domain.
Of course, not all type of knowledge is free.
Cultivation manuals, blueprints, and recipes have patents that you need to pay for.
Otherwise, there would be no creativity, as people could simply copy what the predecessors did.
"Let's see," Maximus slowly walked alongside a wide selection of exercises that extended like infinity.
The Arcana library uses an advanced space folding array, making this gigantic building have a world of its own inside.
As the books are only tier 0, there are no special shielding runes that block spirit consciousness from accessing them.
