Cultivating Black Demon

The Cloud Whale continued to move through the battlefield when Krune thought of something, layering it with ice before turning it invisible. By the time it had crossed half the battlefield, the Cloud Whale had vanished from the eyes of everyone. 

And right as it had done so, it accelerated, soon reaching the end of the battlefield before taking off to the skies, having crossed the range of the Abyssal Trench. Krune stared down, looking at the demons climbing up the flight of stairs towards the battlefield, focusing at the bottom of the stairs to see a Black Demon sitting there as usual. 

Surprisingly, it was there as he had expected. The Black Demon was cultivating. Despite losing the horn in the treasury, it seemed to have created a current of Spiritual Energy towards itself, relying on the stream to siphon out more Spiritual Energy.
