Squeak, creak, rumble, rumble, rumble...
Several Abyssal Devil Race elites, led by Abyssal Devil Ancestors, sped forward at full tilt, charging toward the towering Metal Continent enthroned in the void. Under the rules of the Endless World, so-called speed and slowness had never been absolute, but relative.
"What was that sound?"
The Devil Ancestor with the sharpest perception kept peering into the depths of the void, yet discovered nothing. He turned his gaze once more toward Eternal Sky City's Metal Continent, but the continent was simply too vast. Even looking out from the void, these Abyssal Devils could see only a portion of Eternal Sky City. The farther reaches of the Metal Continent beyond their field of vision had been swallowed by the void's gray gloom.
Then, having realized something, the Formless Devil Ancestor warned cautiously, "Something's wrong. The spacetime pressure here is rising. Be careful!"
They needed roughly another three hundred sand-seconds to reach Eternal Sky City. The void was utterly empty, a change far too drastic from the earlier assault. It had already cast a veil of conspiracy over this stretch of void and filled the attacking devils with waves of unease. Now that the Formless Devil Ancestor had issued such a cryptic warning, the devils, whose nerves were already stretched taut, were completely set off. Like men who saw enemies in every blade of grass and every tree, they all searched for the source of the anomaly with everything they had.

Spacetime pressure could likewise be calculated in units of "degrees."
Under normal circumstances, tranquil void usually had zero degrees of spacetime pressure. It was
