In the winter of the twenty-seventh year of Yong'an, Shen Qingci, the eldest princess of the Great Yao, was framed by Consort Lin and condemned for "plotting rebellion and murdering her mother." Thrown into the cold palace, she faced the death of her elder brother, the deposed crown prince, who was also to be executed. With no way out, she fought back. Aided by Xiao Ce, the Northern Garrison General, who brought her secret reports, she exposed the truth: the incriminating "letters of treason" had been forged. For now, she escaped imprisonment.
But before the turmoil had even subsided, she discovered that Consort Lin had allied with a secret faction in a neighboring kingdom, intent on overthrowing the Great Yao. The once-spoiled princess shed her innocence and began to tread carefully through the power struggles of the imperial palace. While investigating her mother's death and clearing her brother's name, she joined forces with Xiao Ce to fight their hidden enemies. With a fragile body, she shouldered a heavy responsibility, forging a legend of a woman who protected her kingdom through rebirth.
