Boom—
Another thunderous noise echoed as the island's strata cracked further, reaching the depths of the underground ruins.
Chunks of earth and stone, having lost their support, tumbled into the ruins, smashing into the water and creating sounds of splashing streams. All this, mixed with the still unreceded storm around the island, even conveyed a sense of approaching apocalypse.
However, the changes did not stop there.
Amid the surging magic power and the falling earth, a pitch-black fog, akin to the abyssal darkness, began emerging before everyone's eyes. The entire ruin was left in darkness, as if it were a living Hell on earth.
"..."
"Power of Hell?"
Midair, the arm's wielder also noticed the changes beneath the ruins.
The action of gathering magic power to expand the distortion increased abruptly, even the tone carried full caution.
"The successor of the Three Pure Realms school is still here!"
