Demon Lord's Cultivation Level Has Dropped Again

The ends of the demonic path, the immortal path, and the path of body refining are all ascension. In front of that door, I glimpsed the most beautiful scenery and fell into the deepest abyss.

When I encounter danger, I can mobilize Nascent Soul-level powerhouses to protect me, so I still have the power to protect myself.
