This is an ancient love story full of twists and turns and affection. Muyun Wan'er, the daughter of the Minister of Household Affairs, went up the mountain to pray for her father. On her way back, she was besieged by bandits. Fortunately, she was rescued by the emperor Zhao Chenyu, but she had close contact with the emperor because of being drugged. Later, Wan'er became pregnant out of wedlock and was expelled from her family, struggling to make a living in the suburbs.
The emperor never forgot Wan'er, but the queen mother frequently urged him to choose a concubine, and used birthday banquets to summon the daughters of officials of third rank and above who had not left the palace to enter the palace. Mu Yun Wan'er participated without knowing it, but Mu Yun Changqing maliciously accused her, and the Queen Mother wanted to kill her with a stick. The emperor arrived in time to protect Wan'er, but the emperor's teacher tried to dissuade her to no avail. Mu Yunche even tried to plead for his daughter and even hit a pillar.
At a critical moment, Wan'er's child appeared, and its appearance aroused the Queen Mother's suspicion. After questioning and Wan'er's nod for confirmation, the emperor identified it as his own child. Due to jealousy, Mu Yun Changqing and her father Mu Yunhong blamed each other, and finally confessed that Mu Yunhong instigated the bandits to defile Wan'er. The emperor ordered a thorough investigation, and after the truth was revealed, the criminals were severely punished. Mu Yun Wan'er was named queen, his son was the prince, and his daughter was the princess. The emperor doted on the queen alone, creating an eternal legend.
