看本宫灭了后宫三千佳丽
[kàn bĕn gōng miè le hòu gōng sān qiān jiā lì]
This username is inspired by the ancient Chinese imperial harems where an emperor had many wives and concubines. '本宫' refers to the speaker herself, probably identifying with a royal figure who boasts her dominance over the other women ('后宫三千佳丽') in the harem.
