In the middle of the valley, there were dozens of enormous iron anvils, hammers, and tongs. By their size alone, it was evident that they were the playthings of the Difeng Giant. Scattered across the ground were numerous partially finished steel products. Several bubbling volcanic vents, fiercely spurting out blue and red flames, were located near the anvils. There were stone platforms built over these flaming vents, and adjacent to these, stood massive clay crucibles equipped with handles.
During their leisurely conversation, Elder Tang Jin informed Liu Zhenhan that smelting underground was actually quite easy. There wasn't a need to mine or fire up a furnace; scooping from the rivers of lava would suffice. These rivers of lava frequently flowed with molten iron, much like fishing, with a bit of patience, one could quickly obtain their raw materials. Moreover, the iron in these rivers was a high-quality mixture of metallic steel.
