The moment Arlon confirmed his choice, the same rumbling and air-cracking sounds echoed throughout the floor.
Every time a mana pulse waved through the floor, the blue flames in the air moved.
It was an unmistakable phenomenon, one he had encountered multiple times before.
He narrowed his eyes slightly as he felt the vibrations in the ground and the strange way the mana twisted through the air.
"So, this wasn't because the Tower was broken," he thought.
He had suspected it before, back when he first noticed these anomalies, but now he was certain.
The instability, the distortion of space, and the oppressive presence of mana saturating the battlefield—none of it had been an error in the Tower's mechanisms.
This was simply how the Tower functioned at this level, how it created its challenges. He had climbed high enough now that nothing about the process could shake him.
