Advent Of Bloodthirtsy

However, while Nier might overlook that one detail, Rosaline couldn't.

She was an immortal expert who had experienced much in the world, and she had picked up enough clues now to conjure a ridiculous guess that Leonardo wasn't in origin a mortal, but there was a missing piece in history that she couldn't obtain.

Perhaps if she went to personally investigate Earth? She shook that idea away. Let alone immortals, even saints are a disaster in a place like the lower realms. She felt something was odd ever since Leonardo impregnated Nier.

Usually, even in the case of having one's constitution remodelled, it is impossible to impregnate a life form with an innate superiority. Although Leonardo's cells might have been upgraded to contain enough energy, allowing him to safely practice immortal cultivation techniques, his genes should have been those of a mortal.
