Considering Miriam, Nadia, and Kathy had already awakened their bloodlines, their tribulations when advancing their realms were not that difficult. Miriam and Kathy become Void stage experts.
They had already awakened their bloodlines, so nothing out of the ordinary happened besides the breakthrough and getting even more beautiful.
As for Nadia, she was a sage when Klaus locked her cultivation base, but that didn't stop her from becoming a Transcendent and climbing to the peak of that stage.
She had also awakened her bloodline long, long ago, which perhaps counted toward her rise through the Great Sage and Soverign stage.
But as someone who doesn't have combat power, awakening a swordsmanship class that allows her to use a sword like an expert makes her very powerful.
Klaus's Star Monarch blood truly made her someone worth fearing.
