At that moment, Diya was squatting in the lumber mill looking for usable materials.
The lumber mill connected to the outside of the den, where huge machines devoid of engineering aesthetics protruded into the dense forest like fishing rods. Driven by Technique Spirits, environmentally friendly trees, quickly grown by time, would be transformed by the machines into cubic pieces of wood that fell into the den.
Logically, if ferocious dragons don't make use of lumber and it occupies a large area, it should quickly burst the limits of the den; but in reality, there wasn't much lumber in the mill.
As Diya searched for materials, she also took in lessons from her sisters:
White Queen: "Princess, you can't just hand things over so directly."
Diya: "What, should I throw them instead?"
White Queen: "That's not what I meant... doing it like that will make the Observer feel embarrassed."
Diya: "( ̄△ ̄;) I don't understand."
