Inside the Sword Heart Martial Arts Hall.
Lin Mo read through all the books and records on Arrays within the Four Great Martial Arts Schools. The Nine Continents Secret Realm was originally the base of the Nine Stars Sect, but after some unexpected events, the Nine Stars Sect suddenly disappeared, leaving behind incomplete records.
Lin Mo studied Arrays for a long time. Indeed, there was some information about inscriptions on the Prison Tower recorded inside.
In his previous life, Lin Mo was a master of Arrays. Although he had never seen this type of Array, by analogy, he discerned some key points within a few days. Although he couldn't reinforce the Array, he could repair some of its flaws.
No matter how powerful an Array or Magic Treasure may be, it can't resist the erosion of time. The Array on the Prison Tower had been etched for countless years, and even when the Nine Stars Sect was around, it was repaired several times.
