In the previous life, the female counselor Gu Jianwei was betrayed by the king and her best friend, and her blood spattered the Golden Palace. After her rebirth, she became Yun Qichi, a criminal slave in the north. Carrying deep hatred and prophetic vision, she lurked in the dust, vowing to avenge the corrupt powerful people of both countries.
Pei Dingjiang, the governor of the northern border, was criticized by the court as a rough warrior who "supported his troops and respected himself", but in fact he was rough on the outside and careful on the inside, caring about the people. When they first met, one was a lowly sin slave and the other was a high-ranking commander. They regarded each other as chess pieces. However, in the baptism of blood and fire of resisting foreign enemies and guarding the border, they caught a glimpse of each other's talents and sincerity - her strategies helped him repeatedly overcome crises, and his responsibility allowed her to regain her original intention. They gradually used each other to become soul confidants who depended on each other for life and death.
At the same time, Lin Qingci, a close friend from the past life and a scholar of Qingliu, met Su Wanlan, a tiger girl from an enemy general. They met in the cracks of hatred between the country and the family. In the reality of the opposing ideals and positions of "He Qing Haiyan", they were pulled to the extreme, interpreting the tragic feelings of confidants.
When powerful enemies from the north invade in large numbers and the survival of the family and country is at stake, personal grudges become a blur. Yun Qichi and Pei Dingjiang united with Jianghu forces, court officials, and knowledgeable people from enemy countries to jointly resist foreign aggression and protect Chinese civilization. After the crisis was resolved and the new dynasty was initially established, the two saw through the illusion of power, refused the reward, went into seclusion hand in hand, and lived a free and easy life of "you must have all the fun in life". The regretful endings of Lin Qingci and Su Banglan further confirm the core of "I am not alone in my path, and the mountains and rivers are the proof" - true perfection is the open-mindedness and tranquility of building a peaceful world with comrades after overcoming hatred.
