On the day when I was fifteen years old, it was snowy and windy in the north. Under the worried eyes of her brother, the princess Xiao Mingyue embarks on the road back to the capital, bringing with her four maids with special skills, and a secret organization "Aoxuetang" that can subvert the government and the opposition.
On the way back to Beijing, the mysterious assassin's sword and sword revealed a mystery that had been buried for five years - by whose hands did the father of the God of War who died on the battlefield die?
The royal welcome from the capital was the prelude to her return to prison. At the palace banquet, a sword dance stunned everyone, but secretly he had his first confrontation with the powerful chief minister Shen Yan. One is an orphan who avenges her father, and the other is a powerful minister who plays chess for the country. In the turbulent court, feelings are secretly born between temptation and suspicion.
As the investigation deepens, she discovers that her father's death involves an intricate network of interests: nobles embezzling military pay, civil servants collaborating with the enemy and betraying the country, and murderous intentions hidden in the harem... And Shen Yan, who has always been watching with a cold eye, seems to have known all the truth.
"Does the princess think that revenge is the truth?" Shen Yan held the chess piece and chuckled, "In this game of chess, you and I are just pawns."
The blade is about to be unsheathed, and the truth is about to be revealed. Gu Luan returned to the palace not to regain his glory, but to burn down this hypocritical court.
