"A peerless great demon was suppressed in this space. It died when its Lifespan ran out. This must be the Primordial Demon Essence it left behind after its death."

"However, that peerless great demon fell long ago, so it has no real influence."
As the Black Dragon spoke, his gaze returned to the open box.
'A box that can hold such a thing can't be simple. Perhaps the peerless great demon's mortal remains are inside.'
