Bai Yi had always been unable to develop any means for her subjects to utilize metal.
She could only expand through the consumption of biomass, and although she had become unparalleled on this path, nearly able to achieve 100% conversion of biomass,
biomass is only a minor part of the natural world. There's much more matter that is inorganic, belonging to the rock-metal mixtures buried deep underground.
And before this gene arrived, Bai Yi's only way to make use of it was through the slow absorption of corresponding minerals from the soil by plants, thereby indirectly utilizing metal elements.
But this form of conversion wasn't even as fast as letting a witch dig a few times with a hoe to bring back and smelt the ore.
That was why Bai Yi valued Wade and Knight so much in the last Cycle Challenge.
Because the mechanical troops in their hands could provide the territory with an entry ticket to the inorganic world.
