The Wood Spirits of this island aren't particularly strong or weak, David Jones naturally didn't expect them to possess top-grade Epic spirit wood of Level VIII Legends.
Difficult to raise a Flood Dragon in shallow water, the concentration of the heavenly and earthly arcane force around the island was almost incapable of nurturing treasures that reach the legendary rank, to have a Class VII Epic spirit wood was already a representation of Daphne's luck being maxed out to the extreme.
In David Jones's view, the spirit wood occupied by the Level VI Wood Spirits was basically within Level VI; otherwise, with its middle-level Class VI strength, it really couldn't keep it safe.
According to the map information displayed by the Gluttonous Beast, the Wastewater Archipelago belonged to the edge of the Coastal West Zone. It was one of the sea routes for sea creatures entering the coast from the open sea and a sea area where the water-type Beasts are generally weaker.
