Led by the Bronze Tribe, the main force followed the Tianhe and flew in a mighty procession to the Bronze Tribe's home world—the Bronze Plateau.
It was a vast world of overlapping mountain ranges, with a complex and harsh environment.
This place was utterly unsuitable for farming. In truth, the Barbarian Giant Tribe had never been skilled at cultivation. Their ancestors had lived by hunting for generation after generation, at most supplementing their prey with livestock.
Besides that, the Bronze Plateau also produced a metal the Immortal Alliance called spirit bronze. The giant ancestors used crude methods to refine spirit bronze and forge weapons such as spears. Only then did the Barbarian Giant Tribe become the apex of the food chain in the Bronze Plateau world, where Fierce Beasts ran rampant.
Later, after the tribe submitted to the Immortal Alliance, they accepted the Alliance's cultural guidance. Their wisdom was further awakened, and with the Immortal Alliance's technical support, they began mining spirit bronze on a large scale.
According to the Immortal Alliance's grading standards for artifact-refining materials, spirit bronze was a precious fifth-grade material. It could serve as the core primary material for Purple Mansion treasure artifacts, as a supplementary material for Divine Ability Spirit Treasures, or even as a valuable core construction material, such as for the hulls of Void Ferries.
As such, artifact-refining materials as widely applicable as spirit bronze were in enormous demand within the Immortal Alliance.
Huge quantities of spirit bronze flowed continuously into the Immortal Alliance as tribute or trade goods, becoming nourishment for the Alliance.
The Bronze Hall, the Bronze Tribe's large Void Ferry, was a hereditary treasure created after their ancestors had accumulated immense amounts of spirit bronze and gritted their teeth to hire Immortal Alliance artifact refiners.
