Dong Su explained to everyone, "I have consulted several predecessors who have survived on Hidden Island, and each time Hidden Island opens, the methods of acquiring Wisdom Stones are somewhat different."
As he spoke, Dong Su took out a small notebook and glanced down at it.
He continued, "For example, one predecessor said that to obtain Wisdom Stones, one needs to catch a special kind of fish in the water. This fish has a red tail, and as long as you catch it, it's guaranteed to turn into a Wisdom Stone."
Dong Su turned a page and said, "Another predecessor said that perhaps Wisdom Stones need to be searched for in a special kind of tree. That kind of tree bears golden fruit, and as long as you obtain the fruit, it will turn into a Wisdom Stone."
"Yet another predecessor claimed that they had to kill a kind of skeleton with ghostly fire in its eyes. Killing the skeleton would yield a Wisdom Stone," he added.
