When I which political dramas, I always take notes of the revealing plot and make predictions, and sometimes they're true, so please forgive me if I make a prediction and it actually happens in the drama.
My thoughts:
Everyone wants this "Divine Talent" Mei Chang Su with brains.
Empress and Noble Consort Yue - we can see the rivalry between them and their sons because of the fight for the throne. It looks like Noble Consort Yue is more favoured since she helped the Emperor to his seat.
In Episode 2, things begin to unfold more.
So it is revealed that Marquis Ning, the father of Xiao Jing Rui and the residence where Mei Chang Su is a guest at, is actually working for the Crown Prince in secret. They also mentioned this in the drama, did Mei Chang Su live in Marquis Ning's house on purpose knowing the head of the house is working for the Crown Prince or is it just a coincidence? Also, why did Marquis Ning turn a blind eye to his 2nd son Xie Bi working for Prince Yu, his benefactor's enemy?
Prince Jing is highly unfavoured. Sad.
Grand Empress Dowager called Mei Chang Su "Lin Shu", the dead fiancee of Duchess Ni Huang. Could that be his real identity?
What is Lin family's history and Chiyan Army's history?
Revealed Xia Dong's dead husband is General Nie Feng was a result of treason by the Lin family and there was irrefutable evidence, yet Duchess Ni Huang, her best friend trusts the Lin family because of her relationship with Lin Shu. There is still that between them.
Anyhow, I didn't take any screenshots.
