The nurse was just an intern, fresh out of college. She had never seen corruption and shady dealings up-close before this, and the thought of getting involved in an evil scheme scared her.
Dr. Xia had picked her to be his accomplice precisely because he knew she was timid. Fresh graduates like her were the easiest to control.
"Just do as you're told, and shut up. I'm warning you: you're already in this with me. There's no backing out for you now," growled Dr. Xia menacingly.
And then, not wanting to scare the nurse away, he hastily added in a gentle voice, "Don't worry, I have it all worked out. The big boss behind this will be paying us handsomely. Even if this gets out, we'll just say it was a medical accident. If someone finds out about this before the surgery, we'll say it was a diagnostic error. Got it?"
