What is the ending of my medical princess in the third season?

Dragonfly won the world overnight. According to the plot outline of My Doctor Princess, we can know that we have solved Qin's non-night poison and helped Dragonfly get the boundary of night. Dragonfly made Yunxi Han the queen at night, and the queen loved and was happy all her life. My medical princess is not easy to provoke, which mainly tells the story of mutual achievement and redemption between the woman as a modern doctor who came through and the former prince Chu Chenxuan, the "first god of war" of Chu State. The god of war is "killing", the doctor is "redemption", and "angels in white" redeemed the "lonely and brave king". Chu was born handsome, smart, brave and resourceful. He bears the revenge of killing his father, which makes it easier for a cloud to heal a person's heart. From mutual disgust to letting go of prejudice, and then to mutual appreciation, their feelings gradually sublimated. In the process of helping Chu to complete his country and the world, he shared weal and woe, opened his heart to each other, and Qi Xin worked together to heal the people and solve the sufferings of the world, and finally achieved great success.
