The abnormal official ship at the water transport terminal led to a major arms smuggling case that shocked the government and the public. The seventh prince Yu Wenqing was ordered to investigate the case, but he fell into a frame-up and serial killing by his brother. In times of crisis, the mysterious woman Ling Xuanshuang follows him like a shadow. She has superb martial arts and is ordered by her master to go to the capital to protect him from death.
From suspicions at the pier to murderous intentions in the hunting ground, the two formed an alliance between intrigue and blade. She helped him break the situation and take power, and he promised her his absolute trust. However, when Yu Wenqing took an "expedient measure" to take the overall situation into consideration, he completely trampled on Ling Xuanshuang's bottom line of pursuing equality and loyalty. Frustrated, she left a token and walked away.
Three years later, Yu Wenqing, who had become the prince, went to the isolated overseas island "Butie Island" in order to find his lover, only to find that Ling Xuanshuang was the core of the place and had a young son who looked exactly like him. When he put down his identity and tried to make amends, sudden changes occurred in the capital, forcing him to return to face a fatal crisis.
This is a journey about repentance, growth and protection. From the court to the battlefield, from suspicion to trust, the two strong men tempered their emotions in the intrigues and flames of war, and finally ruled the world side by side, creating an evenly matched love legend.
