The Treacherous Minister Seizes Power, and the Entire Court Falls Apart

[Woman Disguised as a Man] [Sickly] [No Romance] [Cold Outside, Unhinged Inside] [Battle Royale] [Villains Locked Away] She gazes at herself in the mirror and gives a scornful laugh. So this is what the infamous traitor whom everyone in the capital wants dead looks like. She is violent, ruthless, cold-blooded, arrogant, and wicked to the core. She forces respectable men into marriage and harasses the academy's teachers. The officials all think she is obsessed with money and women, and that she uses her power to line her own pockets. But no one knows that all she has ever wanted is to topple the dynasty and seize the throne! Her former classmate keeps silent, only to pave the way for her. The aloof Imperial Preceptor silently recites Buddhist scriptures as he puts himself in the middle of the game. The man who seemed as close as a brother smiles as he faces death. Her young guard risks his life to protect her... Her eyes bloodshot, she turns the blade in her hand into a soul-reaping weapon, driving her enemies down into hell and leading the wicked into their doom. She seeks revenge with all her heart, even if she has no one left at her side. “No one left at your side?” Her gentle, refined classmate: ? The aloof Imperial Preceptor: ? Her proud older brother: ? The unassuming guard: ? At the morning court, the emperor frets over state affairs and sighs without end. She arches an eyebrow and smiles arrogantly. “Your Majesty, I have a plan. Allow me to explain...” The officials are distraught. “This is utterly inhumane!” Jiang Yushuang: “I have another plan. Allow me to continue.” The officials are overcome with grief and despair. “Lord Jiang, could a person really come up with this?!” The dynasty changes, and a new emperor takes the throne. To everyone's shock, the new emperor is a woman, standing with her hands behind her back in a brilliant red dragon robe. The people of the realm: This is improper... After they get a good look at her face, they reconsider. Well, actually, it makes sense. (The setting is fictional. The protagonist is no saint. Please don't nitpick or read too much into it.)
