Cheng Rui Jr. in Chang 'an Nuo was the third prince of Shengzhou and later became the emperor of Shengzhou. In his life, Cheng Rui met two women who were very important to him, one was Helan Yun Qi and the other was Helan Mingyu. Helan was Xiao's first wife, and Helan Mingyu was Xiao's concubine when he ascended the throne. So who did Cheng Rui Jr. like in Changan Nuo? In fact, Xiao Chengrui wants to catch the handle of the small program when he marries Helan Mingyu.

Little Cheng Rui likes Helan Yun Qi. They got married very early, and Xiao Chengxuan, a small program and younger brother, grew up watching Helan Yun Qi. Helan Yun Qi is a very gentle woman who always treats her husband and brothers and sisters with the gentlest attitude. She was very sad when she learned that Cheng Rui Jr. had killed the mother of the little program in order to inherit the throne naturally.

However, Cheng Rui Jr. is her husband after all, so she has to cover up the truth for her husband, Helan Yun Qi, thinking that it was not Leijiacha etc. Later, little Cheng Rui happened to meet Helan Mingyu and was shocked by her amazing appearance. Later, Cheng Rui Jr. found that Helan Mingyu and the applet were in love, so he found a reason for the applet to lead troops to fight.

Under the small design, Helan Mingyu thought it was small? Died in battle? This incident made Helan Mingyu very sad, and then Cheng Rui threatened Helan Mingyu to marry him with Xiao Chengxuan. In desperation, Helan Mingyu had to marry little Cheng Rui. Little Cheng Rui doesn't like Helan Mingyu, but he makes good use of Helan Mingyu to contain small programs.

Helan Yun Qi was sad to know that her husband had married his sister, but after all, on the one hand, he was his favorite man, on the other hand, he also loved his sister, and the matter was dropped. Later, in order to contain Xiao before his death, Xiao also made him and Helan Mingyu's children emperor.
