Xuanrao never knew Jiang Duan was the author of that book.
It wasn't until he was taken away by the officials.
That's when she found out about the good deeds he had done.
She immediately went to the palace to plead for mercy, "Emperor, Empress, he is a pedantic scholar and has offended you today, I hope you will forgive him generously! I will surely keep a close eye on him from now on!"
When Sang Yan heard her say this, she knew Jiang Duan was henpecked.
Good, henpecked men are easier to reform.
She smiled generously, "No worries. You are sensible, and since he is your man, you may take him back."
"Thank you, Empress."
Xuanrao, fearing the Emperor might disagree, immediately pressed Jiang Duan's head down and kowtowed to Sang Yan.
He Ying actually disagreed with just letting Jiang Duan go, but since Sang Yan had spoken, he complied.
"Thank you, Emperor."
Xuanrao similarly pressed Jiang Duan's head down and kowtowed to He Ying.
