The Red Fox: Half Soul
What is a firefly?

Firefly is a yellow flower that can light up at night or be in a dark place. This flower is often found in the world of Orpheus and in the world of Orna. It's just that in the world of Orna this flower is very rare. Existing only in the world of Orpheus is easy to find.

This flower produces unlimited light so Henry sought this flower as his home lighting fish lamp with pollen of this flower. So he no longer thought about a bill and electricity payments that he often used for a lamp.
