A Different kind of Devil Dungeon 2

<20 days, 12 hours, 9 minutes and 4 seconds to System upgrade>

On lenny's first Clash, he was smacked so hard that he literally felt three of the fate binds in his soul instantly break. 

Blood rushed out his mouth as he smashed hard into the cave wall.

As he fell to the ground, so did a lot of crystal rocks off the walls. 

Lenny had the body of a great demon existence in the 5th rank. he was recognizably a strong existence. However, that was greatly limited to his existence in the eighth earth.

Here in the open world, they were many that were far stronger than he was. And this dungeon specially chosen by Kanada was proof of that. 

This Subplane was able to accommodate an existence like Naamah who was in the Arcade Realm. Surely, it was possible for it to have Dungeons that could even flatten greater Demon existences.
