Sometime during Cassius and the Soul Emperors' fighting period, a crack suddenly formed in the skies above the Motherland. Yet it wasn't the Soul Eaters that were invading…
"I, Nightmare King Drakon, have descended! And with my power, I shall make the puny humans of this world bend to my will—"
SHA!
SPLAT!
A stray energy arc from the battle between Cassius and the Soul Emperors instantly killed the Nightmare King. And as it so happened, this energy arc was produced by Cassius, meaning that all obtained Nightmare Essence was his.
The system notifications rang out continuously, informing him of all the power-ups he just accidentally received…
*Ding!*
[You have slain a Low-rank Nightmare King that possessed cultivation exceeding the 9th Nightmare Rank!]
[Your Nightmare Essence Gauge has skyrocketed!]
[Nightmare Slayer Cultivation (7th Stage 2nd Class) → (Low-Rank Transcendent Class)]
