Whether it was the purple demon flames containing an aura of ultimate destruction or the flakes of rule-skin originating from a Level-13 Lord of Dimension, neither was a rare treasure that could easily be sent to Gear Time-Space through ordinary means.
Even though Saine had made thorough preparations in advance, dispatching two successive waves of Mechanical Civilization forces disguised as Evil Swamp Time-Space Beings to venture deep into the perilous heartland of Demon Cave Time-Space on reconnaissance missions, and though those stealthily advancing mechanical scouting forces had successfully made secret contact with Secluded Bamboo Supreme and the others of the Evil Tide Civilization, completing the smuggling transport of such high-end Rule Materials remained exceedingly difficult.
These rare supplies, protected layer upon layer by supreme Power of Rules and possessing qualities defying the heavens, were vastly harder to transport than ordinary dimensional goods.
Take, for example, that flake of rule-skin left behind by the Level-13 Lord of Dimension. It was a residual fragment remaining after the Lord of Dimension's Rule Origin had been stripped away, carrying an extremely powerful source resonance. If it truly passed through the Cross-dimensional Teleportation Channel, quietly left the bounds of Demon Cave Time-Space, and was successfully delivered into Saine's hands in Gear Time-Space, then the Level-13 Lord of Dimension within Demon Cave Time-Space would inevitably detect the disturbance in his own rule fragment at once.

Secluded Bamboo Supreme had also told Saine that these purple demon flames were an anomalous fire born in the depths of Demon Cave Time-Space. Their nature was exceptionally tyrannical and violent, containing demonic power capable of burning all things
