I Play the Kept Man, All to Escape the Empress's Palace

I transmigrated into the castration chamber, yet somehow ended up marrying the empress. The aloof empress wants a eunuch, but I’m a real man. I want to stand up to pee. I want a harem of wives and concubines. I can’t keep pretending. I can’t stay in this harem another day! Then one day, I finally became invincible by living off my wife while still enjoying all the benefits. “Ding! Congratulations, Host. For living off your wife while enjoying all the benefits, you receive the SSS divine weapon, Pangu’s Heaven-Splitting Slash.” “Ding! Congratulations, Host. For revealing your strength, you receive the SSS divine beast, the ancient Taotie.” The empress is utterly devoted to me, but I still want to escape this harem!
