Can her words be trusted?

The emperor could understand why Zhuo Jun wanted this.

If others were her, they would not want to be controlled by others for the rest of their lives and become someone else' marionette.

"If King Jin rebels and is executed in the future, I will allow you to change your identity to become a woman and start a new life. 

"I will also help you arrange a new identity."

It was naturally impossible for her to become an official, but it was not a problem to arrange for her to be a merchant or a young lady from a small family.

In the future, when she got married and had children, Zhuo Jun's life would be complete.

Zhuo Jun bowed to the emperor. "Thank You, Your Majesty.

"I am also willing to serve, Your Majesty."

She naturally knew that one had to give in order to gain something.

If she wanted freedom, she had to help the emperor deal with King Jin.

The emperor liked to deal with smart people.
