After Three Years of Pampering Alone, She Became a Noble Concubine, and the Emperor Died?

[The sober heroine is neither pure nor a virgin + the beloved concubine who is cold on the outside and cold on the inside VS the sinister and willful emperor + unconventional opening + careerist without golden fingers] In the three years since she entered the palace, Shen Qingshuang has worked hard at every step, from being an unappreciated concubine to being a noble concubine. The emperor who did not want the two countries to go to war and loved her so much passed away, and she became a prisoner of Ying Zhan, the fifth prince of Northern Yan. Ying Zhan ascended the throne and proclaimed himself emperor, and the concubine's sister became queen, but she was kicked out of the palace and entered a temple to practice medicine. The eldest sister enjoys all the glory and wealth, but she is being bullied in the wilderness. With her life turned upside down, can her fate turn against the wind again? Shen Qingshuang said: I can. So she became Shen Qingxue and returned to the emperor. From Dazhou to Dayan, it's just a matter of changing men. In the harem, what she learned three years ago was to fight for favor, and three years later she sought power. Then enter the palace to eliminate opponents, fight against concubines, and kill queens, just to reach the highest position. ———— When Shen Qingshuang first met Ying Zhan and called him "brother-in-law," he only found it interesting. When it is completely defeated, Ying Zhan: I am willing to give everything I have, including power.
