Xu Ji, the son-in-law of the Wang family, was born in a poor family and was a direct official in Bibu. He was the "son-in-law" of a high-ranking family. In the court, she used accounting books as a blade to eliminate corrupt officials and seek justice. Wang Funan, the son-in-law of the Wei family, is the seventh son of a man who is proud of the spring breeze, and is envied by everyone in his bright clothes and angry horses. On the battlefield, he rushed to kill the enemy again and again, fearlessly wrapping his body in horse leather, just to protect his home and country. However, the court was now in danger and on the verge of collapse. People's livelihood is in ruins and traitors are rampant. The closer they get to the center of power, the more they are swept away by the storm. Although the situation was difficult and dangerous, Wang Funan always thought of the night the two of them slept side by side in the mountains, and the calm look in her red eyes when he deceived her in the dark alley to reveal her identity. She has her own gentleness, but also perseverance and pride, and is not afraid of the wind and frost swords. This lonely courage has long been transformed into blood and sinews. The city can be broken, but the faith is undying - even if the building collapses, I still believe that a spark can ignite the source.
