"Guo Kai. The King of Zhao doesn't know you were captured by Qin. Upon your return to the Zhao state, you are to continue in your role as Prime Minister. Should I have any tasks for you, I will send someone to inform you. Of course, you may also choose not to act. However, if you refuse, I will publicize the secrets you've shared, along with the silk manuscript pledging your allegiance to me. In that case, Zhao will certainly not tolerate you," Ying Zheng said, gazing at Guo Kai.
