In fact, Gu Yuan had already visited the Nanpo Water Realm once.
This was just before the Daoist School was about to campaign against the Red Moon River.
The reason Ma Wu and the others couldn't find Gu Yuan at the Cave Mansion was because Gu Yuan had come here.
At that time, Gu Yuan had completed all the cultivation techniques he could master, and coincidentally, the Stone Liquid had accumulated a chance, so he went straight to the Nanpo Water Realm to use the Stone Liquid to examine the opportunities here.
But the Nanpo Water Realm was vast, and at that time, the Demon Race was stirring and preparing for war, shrouding the area in a Grand Array, so Gu Yuan didn't approach closely, only taking a distant glance and viewing some opportunities at the periphery of the Nanpo Water Realm.
And these seven islands were just among them.
Among these seven islands, apart from the known Spiritual Grain, only one island had additional opportunities.
