As evening approached on the second day, the sun set in the west.
Deep within the core of the Moon-Swallowing Demon Cave.
There were two demons of the Early Stage of Integration guarding it.
They were the Nine-Headed Demon Serpent and the Hell Flame Demon.
The Nine-Headed Demon Serpent had a massive body that could blot out the sun when coiled. Each head emitted a lethal venom (erosive bone venom, soul-devouring venom, heart-burning venom, etc.), and its scales were as tough as black iron.
It possessed the ability to regenerate incessantly; the nine heads were interconnected, and if one was cut off, it would regenerate instantly. Only by destroying the core of all nine heads at once could the Nine-Headed Demon Serpent be killed dead.
This ability made it one of the hardest to kill among all combined demons.
