As more and more earth elemental creatures finished their excavation tasks, the obsidian on the ground piled into a small mountain.
Of course, "a small mountain" was just a figure of speech.
It was not a hill several hundred meters high.
If there really had been a mountain of obsidian that large, Herad would certainly have packed up and gone back to upgrade his obsidian battleship.
Even so, Herad was still very satisfied with the amount of obsidian he had obtained in the Silithus desert.
At a glance, the mountain of obsidian looked big enough to form an eighteen-story residential building.
Granted, the obsidian before him was low-purity raw ore.
It still needed refining before it could become true obsidian.
But however low its purity, the raw ore still contained a little over thirty percent obsidian.
The refined yield would be far from insignificant.
By his estimate, it would certainly amount to tens of thousands of tonnes.
Looking at the small mountain of obsidian, Herad drew on the immense power of the Hammer of Khaz'goroth and cast an enormous Flamestrike.
Elemental flames erupted from underground, completely engulfing the area occupied by the mountain of obsidian.
The Flamestrike Herad cast sent flames soaring over fifty meters high and covered a vast area of thirty to forty thousand square meters.
It was also unlike a normal Flamestrike, which dissipated after two or three seconds.
It had already burned for over ten seconds, yet showed no sign of dissipating.
The scene, like subterranean fire burning a city to the ground, continued for several minutes before ending.
To be precise, Herad noticed that the obsidian had melted.
He then stopped channeling fire elemental energy.
Without a fresh supply of fire elemental energy, the supercharged Flamestrike ended.
Under the powerful effects of Earth Magic, the
