Chapter 447 [Purgatory Arena]
A street spans hundreds of meters, with buildings densely packed on both sides, narrow earthen houses lined one after another. If you roughly calculate, on both sides of this street, including the rear row of buildings, there must be at least several hundred houses—and this is on the low side.
Such a setup has been arranged within a radius of five hundred meters.
Moreover, from Chen Yan's perspective, the rough rune looks quite low-level and crude.
In terms of a cultivator's talisman art and array techniques, setting up an array indeed requires inscribing symbols.
But generally speaking, when runes are used on an array, the smaller the better, the more exquisite the higher the grade.
