According to Su Ran's analysis, the column of Purple Fire was as if a skyscraper had risen from the ground, and Stone Bear was currently at the third-floor level, which was why the Air-restriction Stone was ineffective.
Seeing the gathering of Undead pets below, Stone Bear already knew the situation was beyond hope. Despair and unwillingness surged in his eyes. After a self-mocking laugh, he gave up struggling, threw his Mountain Splitting Axe back into his bag, and allowed the Purple Fire to roast him. Unexpectedly, he smelled a hint of roasted meat. "If only I had some cumin now," he thought, "it would smell even better."
The outcome was foreseeable—after Stone Bear fell from the sky, he surrendered without a fight, allowing the bone blade to deplete his health and died honorably.
