After Dressing up as a Eunuch, I Became the Emperor's Younger Brother

Dressed as a eunuch, the system is not easy to use. What could be more miserable than this? What? I am the godbrother of the Empress, and I have a beautiful martial arts master? That's okay. You say the empress is a puppet? The beautiful master just wants to tease me? No! Speak with evidence! With me here, the empress naturally knows how to govern the country, and the beautiful master is also very well-behaved. Who I am? I'm just an ordinary eunuch.
