Chapter 503
The underlying structure of the formation differed, but the sense of confinement and sealing everything off was identical.
Li Fan could even make a bold assumption: the inspiration for the Tianxuan Spirit-Locking Formation might very well have come from this 'Xuantian Nether-Locking Formation'.
The term "Xuantian" was hard for Li Fan not to associate with the Xuantian Sect, which had long disappeared in the annals of history.
"Could it be that the strange occurrences in the world can be traced back to the time when the Xuantian Sect still existed?"
"Does this mean that even in the Fallen Immortal Realm, one could encounter strange anomalies?"
Li Fan pondered while studying the formation diagram, his thoughts wandering.
The formation diagram was crafted using some special technique and was encrypted with several restrictions, making it impossible for outsiders to view the complete structure of the Nether-Locking Formation.
It allowed those who were not skilled in formations to operate the formation in a simplified manner, outputting its effects externally.
"This is quite ingenious!" After studying it for a long time, Li Fan temporarily gave up on understanding the full structure of the Nether-Locking Formation and sighed in admiration.
