And the bad news doesn't stop there.
The selected rock formations were already severely weathered and structurally unstable to begin with, for the purpose of blasting them with explosives.
The distance between several rock formations was not very far, as the plan was to hit the Molten Mountain Dragon hard in one go. It's definitely better for all to collapse at once rather than one by one.
On the rock formation that was accidentally detonated by the Extinct Dragon's spiked "stray bullets",
a massive amount of explosives, in an instant, formed a semi-transparent spherical shape in the air, centered at the point of detonation.
This was an optical anomaly caused by the rapid compression of air.
Inside the sphere were fragments of rock flying outward, flames, thick smoke, and scattered ash...
These debris quickly turned the breaking point of the rock formation into a mass of earth-colored smoke.
