Dark Heaven Domain!
When the Devil Emperor unleashed his domain, even Yang Ming, who watched through Illidan Stormrage's eyes from an entire plane away, could not help being shaken!
It was called a domain, but the Devil Emperor himself was already infinitely close to the realm of a Newly Promoted God. Unleashed with his Quasi-God cultivation, his domain already carried a hint of the power of rules found within a god domain.
Within the Devil Emperor's pitch-black Dark Heaven Domain, where one could not see even the fingers of an outstretched hand, not only did light and heat vanish, but the water, wood, and other elements within the heavenly origin power were rapidly drained away, turning the space toward an utterly empty vacuum.
What was a vacuum?
According to the definition in physics, a vacuum was a gaseous state with pressure below one atmosphere within a given space.
In a vacuum, sound could not travel because there was no medium, but the transmission of electromagnetic waves remained unaffected.
When the oxygen content outside the body plummeted, the difference between internal and external pressure would also inflict tremendous damage on the body.
For abyssal creatures that lived year-round in extremely harsh environments, a drop in oxygen concentration was nothing. Moreover, none of the Abyssal Emperors present were ordinary beings. Some could even traverse the void with their physical bodies, so the effects on them were limited.
For Illidan Stormrage, however, who was encountering such a hostile environment for the first time, it was an utterly miserable experience.
At that moment, Illidan Stormrage could feel that he was almost unable to breathe. The oxygen content within the Dark Heaven Domain was practically zero. He could only temporarily shut down his respiratory system and rely on the internal circulation of his demonic body
