"Combing The Island"
The previous family didn't build a base like Ainsley, but they did have various treasure-hunting tools or temporary residences scattered all around the island.
Ainsley generously took over these places and started to comb the entire island while doing a treasure hunt.
On the first day of the treasure hunt, Ainsley didn't use any of her luck-manipulation ability, fearing the great side-effect.
Because of this, they found no other treasures aside from more gemstones, strange ores, and a few dead trees.
The dead trees had a darkness-attributed wood, really unique, and it could generate wood in a short time.
The team collected these woods to fill the Sloan Family's treasury.
However, even after searching for a whole day, until the sun slowly hid behind the ocean, they found no other meaningful treasures other than the gemstones.
The gemstones were also very small, just the size of a shirt button or even less.
