Without proper calibration, the puppet would not be able to differentiate between valuable crystal veins and surrounding rock accurately enough.
And worse, it might misjudge the fragility of the quartz, leading to damage during extraction.
To refine this core properly, Han Yu needed firsthand data from the mine.
He needed to observe the quartz directly.
Until then, he could only prepare the structure and leave space for future adjustments.
With that decision made, Han Yu set the analysis core aside and turned his attention to the body reconstruction.
He moved toward the material racks and selected what he needed.
For the primary structure, he chose Dark Grained Spirit Teak.
The wood was dense, resilient, and naturally resistant to environmental degradation. More importantly, it had excellent compatibility with formation engraving, allowing spiritual energy to flow through it smoothly without significant loss.
For reinforcement, he selected Hundred Tempered Iron.
