The reason he dared to say such disrespectful words is because he believed Su Yan would never be able to conceive a child.
According to reports, the Emperor and the Empress enjoy nightly pleasures, and records from the Imperial Hospital show that the Emperor's health is excellent.
If there's been no child, then it's the Empress's problem.
A woman who hasn't conceived in a year is likely never to conceive.
So, these few people seized the opportunity while the Emperor was not in the palace to make a gamble.
In their view, a woman, having no support other than her husband, would surely fear losing her husband's favor; otherwise she would have nothing.
Especially the more noble one's status is, the more they fear losing everything they hold.
Moreover, they are practically prisoners of the Emperor, and even if they spoke such disrespectful words, they believed neither the Emperor nor the Empress dared to do anything to them.
