In her previous life, Su Xue'er, a concubine-born daughter, was used as a substitute for her eldest sister and married Wei Qingchen for ten years. She endured neglect, three miscarriages, and imprisonment in the imperial dungeon before ultimately being forced to drink poisoned wine and dying. Reborn ten years earlier at a palace banquet, she publicly refuses the marriage, exposes the secret affair between her eldest sister and Wei Qingchen, and enters the palace as a consort after earning merit by saving the emperor. Emperor Zhao Yan dotes on her and entrusts the empire to her on his deathbed. Su Xue'er rules from behind the curtain, suppresses rebellions, and ultimately ascends the throne herself, becoming an empress in her own right. Through her life, she proves one thing: in this world, the only person you can rely on is yourself.
