Eye of Earth

It's the Earth's Eye in Rockbole's Land that greatly contributes to Rockbole's Revival. As long as it has the Earth's Eye, it can revive. Now you have the answer. Find the Earth's Eye under a rock near the Zeno Plains and take it to Adventurer Tickle north inside the village. Then convey my message that the Earth's Eye is now gone, so he can hunt freely.

Be quick. If you dawdle like that, the monster will bite you. Find the Earth's Eye under a rock near the Zeno Plains and take it to Adventurer Tickle, north inside the village.

Hmm, what is this? What? Earth's Eyes? Why did he send this? Oh, is that so? It was simpler than I'd thought. Then I can hunt now, right? Okay, okay.
