White Steel Princess did not come alone.
White Knight, Black Knight, and Oak elite soldiers accompanied her to Fertile City.
The Oak bloodline, sharing the surname with the tree, called the Oak forest "Divine Wood Forest."
They believed these trees possessed immortal divinity. During the saplings' growth period, they would sing epic ballads and use secret techniques to enhance the spiritual essence of the Oak, eventually obtaining wood that was extremely tough and high-strength, far surpassing ordinary trees.
The final product was as strong as steel but only one-tenth as heavy.
The elite soldiers of Duke Oak generally possessed equipment made of that material, and he was the only one among the Dukes who could outfit his troops on such a large scale with extraordinary weapons, visibly having three to five thousand Oak elite soldiers.
Reportedly, Oak elite soldiers had sharper ears, higher attractiveness, and agile movements.
