Logan spent a thousand spirit stones to complete the construction of the Killing Array. However, the most challenging aspect of the array was to completely conceal its aura so that no one could detect it, otherwise all his efforts would be for naught.
It was undoubtedly difficult to perfectly hide an array, as it was essentially built and operated using the spiritual energy in the air. Concealing this from a cultivator, especially from a Sanctuary Powerhouse who had already reached that level of cultivation, was even more challenging.
For the sake of hiding the Barrier Array that Logan had constructed, he decided to keep only the barrier that trapped enemies, discarding everything else. Once the Beast King entered the array, Logan would temporarily adjust the layout.
