Chapter 72: Chapter 72: Howling Moon Clan, the Advancing Red Copper Dragon

Needleleaf Valley, Sulfur Pool.

Galos throws pieces of Red Copper Ore into it.

This ore is distributed around Needleleaf Valley, a type of fire element metal ore, which reacts with the Sulfur Pool, creating a high-temperature reaction. The Violent Bears have previously used red copper to enhance the Sulfur Pool's effect, making it boil hotter and produce more steam.
