Ji An nodded in satisfaction and said with a smile:
"The location is very well chosen."
Luoyan Mountain was less than thirty li from Crimson Flame Peak. He only needed a few breaths after leaving his cave abode and using Soaring Golden Light to arrive, so it would not delay anything at all.
Zhang Zeyu added, "True Lord, unlike ordinary defensive formations, a Teleportation Array must rely on a Spirit Vein. Otherwise, the precision of the teleportation will be affected."
"For a Teleportation Array spanning such a great distance, it must be built upon at least a low-grade second-tier Spirit Vein."
He had also constructed the Teleportation Array in the submerged karst cave beneath Azure Dragon Mountain's pool. That place was only a little over twenty thousand li from Falling Maple Valley's mountain gate, so a first-tier Spirit Vein had been enough to bear the burden.
"That is fine. I will leave all matters concerning the formation to you. Make the arrangements."
Professional matters should be left to professionals; an amateur could not instruct an expert.
Zhang Zeyu gave a bitter laugh and continued:
"On my way here, I took note of the situation. The Spirit Veins throughout Harmony Peak's territory have suffered contamination to varying degrees, and their Spirit Vein grades have fallen drastically.
"It will not be easy to find a second-tier Spirit Vein. I estimate that even if we find one that meets the requirements, it will still be quite far from here—at least a thousand li away."
The Harmony Peak region had once been the main base of the True Demon army. The Spirit Veins throughout the entire Northern Lands of Western Continent had been dealt a devastating blow. It could be said that all cultivators of the Northern Lands had been buried with them.
