Beneath Profound Craft Sect City, there was a cave that led deep underground.
There, flames erupted year-round, creating an extremely high temperature that made it the perfect place for forging. Due to the unique properties of the Celestial Crystal Rock, ordinary flames were completely incapable of refining it, so it could only be forged in that place.
And only the War Emperor knew of this entrance to the world below.
Under the War Emperor's lead, the two of them arrived deep underground.
Before they even reached the deepest part, a searing wave of heat billowed out from below, spreading rapidly and making their skin feel as if it were scorching.
In this subterranean place, not a single blade of grass grew. Everything had been burned to charcoal by the high temperature.
"Alright, it's right there!"
The War Emperor stopped.
He pointed to a spot in the depths from which flames were continuously spreading.
