Zuo Zhen truly is an ill-fated person.
In the Da Liang Army, military generals like Zuo Zhen are a dime a dozen. It's just that Zuo Zhen was greedier, extending his hands further. He happened to encounter Jiang Shaohua, who unceremoniously made an example of him to establish authority.
Empress Dowager Zheng seized this opportunity to blow up the issue, forcing Prime Minister Wang to handle it impartially. From the moment Zuo Zhen left the military camp for the Capital City, he was nothing but a discarded chess piece.
Jiang Shaohua had her own sources of information, knowing far more than Li Tie.
