"Phoenix Curtain and Frost" is a costume romance novel that starts from ancient Chang'an and spans the court and the rivers and lakes. It revolves around the love-hate entanglement between Du Yanran, the legitimate daughter of the official minister, and the current Taiwei Dugu Sheng. It composes a fateful relationship that has gone through imperial conspiracy, life and death tests, and finally stayed together.
Du Yanran is gentle and polite, but due to an imperial edict, she is forced to marry Dugu Sheng, known as the "Iron-fisted Captain". The neglect on the wedding night and the antagonism between Liu and her sister-in-law Dugu Yue made this marriage that began with imperial power full of barriers. The startling glimpse of the Lantern Festival was originally the beginning of a heartbeat, but due to Dugu Sheng's coldness and the intrusion of Su Wenxuan, an orphan from the previous dynasty, the relationship between the two fell into suspicion and temptation.
A storm broke out in the court. Prime Minister Li Song framed Dugu Sheng for rebellion, and Du Yanran was also charged with "collaborating with the enemy" and sent to jail. In order to protect his lover, Dugu Sheng had no choice but to set up a trap with the "Heli Shu", which caused the unknowing Du Yanran to leave the house heartbroken and follow Su Wenxuan to the south of the Yangtze River. In the next six months, Dugu Sheng eliminated the traitors, cleared the grievances, and traveled across thousands of mountains and rivers to the south of the Yangtze River, only to see Du Yanran's indifference and alienation towards him.
From the reunion at the Suzhou Lantern Festival, to the side-by-side rescue during the plague, to the life-and-death crisis of the kidnapping of the third prince and the poisoning of the second prince, the two gradually uncovered the misunderstandings of the past while overcoming difficulties together, and also saw clearly each other's deep feelings. Su Wenxuan's sad exit and the dispute over the reserve position were settled, allowing them to finally break free from the shackles of the court. Just as the two were enjoying their retreat in a small town in the south of the Yangtze River, the Huns invaded. Dugu Sheng went out to fight for his country again, and Du Yanran used his weak body to fight...
