"Soon."
If Leon had asked this question ten minutes ago, the tall, thin man probably wouldn't have bothered to respond. If he was particularly annoyed, he might even have thrown in a sarcastic quip or two to relieve some stress.
But now he raised his hand to point above, gazing at the Nightmare River pouring into the night, patiently explaining:
"Within the range of the Demonic Soul Abyss, the King of Nightmares cannot truly be killed. It is quite a cautious type among the Evil Gods, generally not leaving the Demonic Soul Abyss to avoid being eradicated by the Bureau.
And the black river of the Nightmare River is, in a sense, an extension of the Demonic Soul Abyss. As long as it doesn't leave the range of the Nightmare River, it can infinitely resurrect even if killed.
According to past records of the Bureau, once the waters of the Nightmare River completely spread out, providing a sufficiently safe foothold, that's when he will truly descend."
