By the time that Mark crossed the Dungeon Barrier of the Mega-Dungeon, Dona held against his chest, it was already night. Unlike ever before, Mark had some confidence in entering into this dangerous demonic territory.
After all, he was not a simple Demonling anymore. He was a Lower Demon. Even in the entire Hunter World, only the top of the top was better than him.
The A-Class Hunters and Tier 2 Demons were very few in this world, and Tier 1 was the bulk of the demons around. He was already one of the top-level fighters in Tier 1, even though Mark had just evolved.
He had increased his Mind Stat to (High) and his Physical Stat to (Low) for Tier 1. He also had his own assortment of demonic tricks and the intelligence to plot a battle that the other demons didn't have.
More than that, Mark had wings. If things were going downhill, he could retreat.
