Logan was at his wits' end. From the previous challenges, it was clearly a test set by the Sanctuary Powerhouse, but it wasn't just for those in the Holy See.
For those below the Holy See, there was still a chance to seize an opportunity. The first three tests assessed one's enlightenment and posed no encounter with Demon Beasts or other dangers.
What was this fourth trial testing? Moreover, the opportunity might lie just above the Heavenly Ladder! In the depths of his mind, Logan felt he was on the verge of a breakthrough, yet he couldn't figure out the rationale behind it.
Each Sanctuary Powerhouse only mastered a few of the Great Law's paths. Unless one was an all-capable person, no one could ascend the Heavenly Ladder to seize the opportunity. It seemed like a dead end!
