After looking at the formation in front of him using his visual ability, Lothur saw each inscription in the code of it.
That was a standard Iron-grade defensive formation, something that, from what Lothur understood, when activated, would manipulate certain atoms in the air to create a type of fabric. The spiritual energy would connect such a thing, and some low-level Natural Laws would shape its structure to produce something with remarkable resilience.
The practical result of this? The creation of a barrier around a few meters of the formation, capable of withstanding the full force of someone at the 1st stage for some time.
The time in question could range from infinity, for when a mortal would attack such a thing, or 10 minutes if a cultivator at the 9th Transformation were the one trying to destroy this barrier.
