Dressed as a Good-For-Nothing Prince, Kneeling Down and Licking the Empress at the Beginning?

Chu Mu was transformed into the most miserable prince in history, and was stripped of his title and thrown into a prison. A throat injury made him mute, and when he woke up, he became the foot-washing slave of the cold empress... It's a bit rough at the beginning. Readers, please read it patiently. It will gradually get better later! It's not a dream to knock down the empress hehehehehe
