The ending of the characters in "A Long Song of Heavenly Prosperity" is that Feng Zhiwei chose to jump off a cliff in order not to become the authority and obstacle of Yining, and Yining embarked on the road of emperor with the mission of the world. Xin admitted that he killed the king and was forgiven. After the natural emperor lost his imperial power, Feng Zhiwei chose to let him live.

In the play, Feng Zhiwei and Yining have a three-day contract. Three days later, if Yining can prove his innocence, Feng Zhiwei agrees to marry him and become the queen of Yining. In these three days, Xin Xiang admitted that Wang designed to kill herself, and felt that she had not misjudged the wrong person, so she helped Xin up and continued to work beside her.

Yining found the person who framed herself and proved her innocence. After three days, Yining brought Yue Ling to Feng Zhiwei, and there was an arrow on how to be honest. Feng Zhiwei immediately understood that this was deliberately seen through by He Lianzheng, who had framed Yining. After Feng Zhiwei came out, Yining immediately asked Feng Zhiwei if the three-day agreement counted.

On the surface, Feng Zhiwei promised Yining, but in fact he played a familiar tune on the top of the mountain. After hearing this song, Yining only pulled Feng Zhiwei to do something. Sure enough, Feng Zhiwei jumped off the cliff. Yining became the emperor alone and wanted to know everything.
