"Then I will advance to the Expert Stage with my own efforts."
Thyra muttered with a determined look on her face.
She was an assassin and although she wasn't given a choice and was pretty much forced to work as an assassin, she now craves power and strength.
If becoming an Expert Stage Cultivator through sex makes her weaker than a normal Expert Cultivator, then she will become an Expert Stage Cultivator on her own.
"I hope you achieve that," Nux muttered as he patted Thyra's head.
Thyra then closed her eyes and enjoyed the pats.
"However," Suddenly, Nux muttered.
"Hmm?"
"I suggest you become an Expert Stage Cultivator as soon as possible, don't expect me to hold back, I am telling you now, if I become an Expert Stage Cultivator faster than you,
I'll pull you into the room, ram my cock inside your little sister and will make you an Expert Stage Cultivator as well~" Nux whispered into her years seductive.
