Murong Xue, the direct granddaughter of the grand master, and Xiao Chengyu, the current prince, were childhood sweethearts. She was also the niece of the imperial concubine who was deeply loved by the emperor. When she reached her age, a marriage decree decreed that she would be given to the prince as a side concubine. In order to gain the support of the family and military power, the prince successively married Gu Jinxiao, the daughter of the general who ruled the country, as the crown prince, and Shangguan Qian, the daughter of the prime minister, was a concubine. She happily married into the East Palace and understood that the young man needed the support of the family. However, when she was pregnant with the prince's first child, she was poisoned by Shangguan Qian, who was also a concubine. However, the prince needed the prime minister's support for the throne, but did not pursue the matter and took it away by accident. However, it was not until this moment that she realized that the young man would no longer be the same as before. He was the future emperor after all, and he had to weigh the pros and cons in everything. However, after the prince ascended the throne, he made the murderer of her child a concubine with her. When she sacrificed herself for the sake of the overall situation again and again, she knew it was time. When it was time to withdraw, she used the help of lower-ranking concubines to make the imperial concubine make mistakes when handling palace affairs, taking away her right to co-manage the six palaces. She had a queen who could compete with the imperial concubine's mother's family. When they both lost in the fight, she raised the queen's young daughter and became his successor, supported her own son to become the emperor, and listened to the government behind the curtain.
