Old Mrs. Lu glanced at the dishes on the table before leaving and then at the butler, saying, "The servants in the kitchen need to be replaced; they don't even know what Lady Sun likes to eat."
The butler immediately bowed his head, his back sweating as he replied, "Yes!" That look from the old lady was clearly a warning to him.
If he couldn't satisfy Lady Sun in the future, he might very well be the next one to be replaced.
This really was a case of 'when the immortals fight, the mortals suffer.'
