If the Emperor wanted to investigate, it wouldn't be hard to find her. Even without evidence, the Emperor knows in his heart; wouldn't he then be even less inclined to come to her chambers in the future? Over time, can she even retain her position as Empress?
The Empress fell into deep thought.
Seeing a glimmer of hope, Honored Lady Hu immediately continued, "Although Noble Consort hasn't lost her child, no one knows whether this baby will be a boy or a girl, or if it can be born healthily, or if it can be raised without incident."
In other words, your chance, Empress, is far from lost.
"Why should you be at odds with the Emperor at this time?!"
Honored Lady Hu's words struck right at the Empress's heart.
She thought about it and her angry expression faded, nodding unconsciously in agreement.
"You do have a point!"
