There's a bird's nest on top of Mount Daigo in the southwest. The King of Sky lives there. You've got to climb up and kill it.
I made a robot with the parts you brought me. When you're fighting atop the mountain, summon it if you need help. Pretty cool, right?
After you kill the bird, please destroy all its eggs, too! The future of Huyi Village depends on you!
If you succeed, please be sure to tell Chief Kumahachi.
