Yu Wanqing was born in one of the most chaotic slums in the capital. She sold herbal tea and performed acrobatics, and developed the ability to observe people's movements and what they said to ghosts. Once she entered the palace, she became the lowest-ranking female prostitute. The good news is that she doesn't have to recite obscure female commandments like other empresses, nor does she have to starve to maintain her elegance. The bad news is that the top ladies in the harem regard her as that "bumpkin who has never seen the world" and dig holes for her every day. "Yu Cainv, this tea is a tribute, are you used to drinking it?" The imperial concubine smiled softly. Yu Wanqing held the tea cup and nodded sincerely: "It is indeed not as good as the tangerine peel tea from my herbal tea shop to relieve tiredness, but the empress is serious about it, I will drink it all." Concubine: "..." Why doesn't this person play according to the routine? The situation in the harem is treacherous, and the concubines are scheming, but Yu Wanqing regards the harem as a business place for upgrading and fighting monsters. There is no golden finger, no system, all she has is the exquisite heart with seven orifices that was forged in the market. Who wants to frame her? With her backhand, she turned the opponent's advantage into her own bargaining chip. Who wants to win over her? She accurately analyzes the pros and cons and maneuvers between all parties. From being a daughter-in-law to being a noble concubine, she walked with every step that was startling, yet at the same time, she was successful at every step. When all the civil and military officials in the dynasty were shocked at how this woman from a wealthy family doted on the harem, Yu Wanqing was sitting in the imperial garden, eating melon seeds and settling accounts with the emperor: "Your Majesty, the expenses of this harem are too great, we have to increase revenue and reduce expenditure!" The emperor smiled helplessly: "You are really my living treasure." There is no superpower dimensionality reduction attack here.
