Heaven's Chosen Villain

Since I'm the villain, what's wrong with taking the reborn Empress as my disciple from the start?

“You wouldn't want your Brother Xiao Miao to find out what happened that night, would you?”

“What? Even the protagonist of a cuckold story is here??”

“A reborn, heartless Empress? I'll take her as my disciple!”

As a villain, I have to uphold the basic principles of villainy: never slander a bad person, and never let a good person off the hook!
