Wei Jinyu is Princess Sin, but she is also the childhood sweetheart of Emperor Yuwen Jinghong.
She suffered all kinds of torture when she was imprisoned by the prince, and gradually healed under the gentle care of Yu Wen Jinghong.
Yuwen Jinghong once promised her that he would protect her.
But Wei Jinyu gradually discovered that she could not always hide behind Yuwen Jinghong. Even the emperor who owned the world would sometimes be in trouble and helpless.
If you are not strong, no matter how powerful you are, you will not be able to protect yourself forever.
Yuwen Jinghong's protection of Wei Jinyu again and again made him pay a huge price again and again.
Wei Jinyu couldn't bear him to continue to sacrifice like this, so under the opportunity of a misunderstanding, she ran away with Bai Jingchen, the prince of a neighboring country.
On the way to escape, Wei Jinyu sharpened herself little by little, becoming stronger and stronger, possessing multiple identities and a powerful status in the world.
In the end, she saved Yuwen Jinghong's life and became a legendary woman in history.
