Shen Qingyi, the princess of the conquered Chu State, concealed her identity and lurked in the enemy country as a medical woman, just to assassinate Xiao Chengyu, the enemy who destroyed the country. She rescued the injured Xiao Yu (pseudonym of Xiao Chengyu) in the valley, and the two secretly fell in love. When Shen Qingyi activated the power of the sky, she saw the tragic ending of the two of them - she would fall in love with him, he would die for her, she would die to save him, and he would perish because of her.
Shen Qingyi decided to change her destiny, but she didn't know that every step was leading to the abyss. She and Xiao Chengyu have opposing identities, love and hatred are intertwined, and the tragic future shown on the sky is like a cage, trapping the two of them. In the end, Shen Qingyi sacrificed the power of the sky to change his destiny, at the cost of losing his memory. Xiao Chengyu awakens her memory with love, and the two rule the world together.
Intention: Love can transcend mountains and seas, love can transcend time and space; destiny can be changed, love can transcend hatred.
