Wen Xinyue had already experienced the power of that little toy.
If Liu Mengyu set the toy to medium, it would make Wen Xinyue gradually lose her sanity, with more pleasure and comfort surfacing.
But if Wen Xinyue forcefully endured it, she could maintain a trace of rationality and not entirely lose her composure in front of Liu Mengyu.
However, once the toy was set to the highest setting, Wen Xinyue would instantly lose all rationality, even to the point of collapse.
Wen Xinyue simply couldn't withstand the stimulation of the highest setting; once it was activated, she would completely break down, quickly losing her sanity.
At that moment, time, occasion, and gender would become irrelevant to Wen Xinyue; her mind would be consumed with nothing but thoughts of men and women.
