Loyal Minister? I'm Quitting

Jiang Ruochen transmigrates to Great Xia and dedicates himself to supporting the Empress Dowager. However, after she ascends the throne, she turns on him, designs traps, and frames him. After being executed, Jiang Ruochen suddenly wakes up back to the day she framed him. Seeing the Empress Dowager holding poison in front of him, Jiang Ruochen vows never to be her sycophant again. He plays along with her scheme, outsmarts her trap, and formally resigns. Just as the Empress Dowager believes she can rule alone, she realizes she has always been dependent on Jiang Ruochen.
