Fang Bai deduced that the piece of Fire Essence Iron at the bottom of Fire Lake must have existed for a long time and that Martial Artists must have known about the possibility of treasures in Fire Lake. However, because the Fire Essence Iron itself was too hot, no Martial Artist dared to touch it. They could only sigh longingly, which is why the Fire Essence Iron was preserved till now.
Fire Essence Iron is the main material for refining Fire Spirit Weapons. The higher the quality of Fire Essence Iron, the more powerful the Spiritual Artifacts that are refined from it. Fang Bai had originally thought that in these Three Thousand Minor Worlds, the best refining material was only of medium quality. He didn't expect to find a sizable piece of high-quality Fire Essence Iron here. It was quite unexpected and a pleasant surprise.
