They say life is like something you can't resist, so you have to enjoy it.
Actually, thinking about it seriously, it's really nothing. Most of the things left in that cave by the Gold Level Great Mage have rotted away, indicating that several hundred to thousands of years have passed. Unless he advanced to Legendary, he would have been long gone by now.
And all these years, there's been no sign of him returning to that cave, it's almost certain that he didn't survive.
With the death of that Gold Level Great Mage, as for the things at the bottom of the nearby lake reservoir, as long as I don't say anything, how would others know? Even if there's some godforsaken big secret hidden there, so what?
Thinking like this, Austin's mood improved a lot.
At least it seems safe for now, and Austin has no need to explore that lake reservoir any further. At least for now, knowing more is unnecessary. The most important thing is to vigorously develop the Clan Tribe.
