Who said "the most ruthless emperor's family"? This book tells the story of the warmth behind the "strict rule" of the legendary "cold-blooded" emperor Yongzheng, the helplessness behind his "seizing of the legitimate son", and his infatuation and determination for his first wife. Xiao Yinzi and Ulanala Wanxi have been working hand in hand for 40 years. Ulanala Wanxi has gone from a naive and infatuated girl, to the independent Fu Jin of Prince Yong's Mansion, to a wise and wise queen. No matter how her roles change, she is always the Wan'er who supports Yinzhen. "I only hope that your heart will be like mine, and you will live up to your love." She promised him a life, and he wanted to give her a life too. The harem is so glamorous and has gone through so many ups and downs. If time went back, would you still be willing to be his Wan'er?
