Plan

It was probably unwise for Rui to stray too much further into the dungeon as the danger levels constantly rose. Even in the Beast Domain, the two of them never went so far as to completely drain their Martial Hearts. Who knew what could attack them in their incapacitated states?

Luckily, Rui still had a decent amount of stamina left. Thus, he could afford to stray a bit deeper to take a good look at what was going on. Thankfully, given how small the manifold was, it wasn't too far in.

"ROOOOOAAAARRRRR!" 

Rui's eyes widened as he saw a slew of emerald dragons launching an assault on a region, lighting it up with their fire breaths. Yet, it was the residents of the region that surprised him.

Angels.

An overwhelming majority of them were weaker than the one he faced, with only three pairs of wings or less. They struggled under the wrath of powerful apex monsters led by a tyrannically large dragon the size of a hill.
