The Hidden Flood Dragon Institute oversees three islands: Bailu Island, Cyan Light Island, and Golden Yuan Island.
Among them, Bailu Island is inhabited by cultivators below the Qi Refining Fifth Layer, while Cyan Light Island is generally home to those from Qi Refining Fifth Layer to Eighth Layer.
The island with the densest Spiritual Qi, Golden Light Island, is mostly inhabited by cultivators at the Qi Refining Ninth Layer, just a step away from Foundation Establishment.
In principle, with Gu Yuan's cultivation level, he could only practice on Cyan Light Island.
But in practice, there is always room for maneuver in any matter.
Golden Yuan Island's Spiritual Qi concentration is extremely high, a genuine Tier Two High-Grade Spiritual Vein, which even outside are enjoyed only by minor Foundation Establishment Sect Masters.
Even within the Daoist School, some minor noble families' spiritual veins aren't as rich, nor would they lavish such veins on their Qi Refining disciples.
