After a thorough survey, Herad discovered a massive magma pool beneath Un'Goro Crater.
On any normal life-bearing planet, there were magma pools beneath every stretch of land.
The distance between a magma pool and the surface varied greatly with elevation.
But the situation in Un'Goro Crater was genuinely rather alarming!
He estimated that it was about thirty thousand meters below the surface.
The figure Herad had roughly measured was not particularly accurate.
Yet even if the data was somewhat off, it was still a far cry from the usual depth of over a hundred thousand meters elsewhere!
With so much less soil and rock overhead, magma could erupt very easily.
Of course, compared with Yellowstone Park on Earth, the situation here was actually quite good!
Eight thousand meters beneath Yellowstone Park lay the largest volcanic system on Earth.
If that thing erupted, it would deal a devastating blow to the surrounding region.
The volcanic ash it spewed could affect the climate worldwide.
Even the climatic effects of a global nuclear war could not compare to a supervolcanic eruption!
Compared with the highly unstable Yellowstone Park, Un'Goro Crater was in fairly good shape.
Besides, Herad had the help of the Hammer of Khaz'goroth. Even if he really caused a major problem, he could forcibly suppress it.
For an earth-and-fire creation-grade artifact, suppressing a volcanic eruption would be child's play, wouldn't it?
What Herad needed to do now, however, was draw the magma out of the magma pool.
That was because nearly all the obsidian beneath Un'Goro Crater had melted into the magma.
After some consideration, Herad decided to modify the structure of Fire Plume Ridge first, making it easier to extract the magma.
The largest vent in Fire Plume Ridge had already been filled by cooled magma.
Only a few very
