The Canglan Kingdom and the Xiao Kingdom have been fighting for years. In order to take a breather, the Xiao Kingdom sent the unpopular prince Lu Huainian to Canglan as a hostage. This young man, who was stripped of his status as a prince and turned into a slave, wore shackles and cleaned the palace roads every day, but he met Nan Tingyi, the crown prince of Canglan Kingdom, for the first time in the snow. When Lu Huainian lowered his eyes and smiled, the cold light of the silver dagger hidden in his broken hair flashed past, but was caught by Nan Tingyi's hawk-like gaze.
As the eldest son, Nanting Yi has been struggling to survive in the harem since the death of his mother. He quietly transferred Lu Huainian to the East Palace for duty
During the interrogation on a snowy night, Lu Huainian was chained to the torture rack but he could still laugh out loud, but his pupils shrank suddenly when Nanting Yi wiped the blood on his forehead for him - it was the same dragon-patterned jade pendant he had seen in his mother's palace when the Xiao Kingdom assassin assassinated the Canglan King twelve years ago.
When the war between the two countries resumed, Nan Tingyi discovered that his mother did not die of illness but was poisoned by Xiaoguo Xizuo. Lu Huainian used Banque's "The Willow Song" as bait to lure Nan Tingyi into the plot that had been laid out long ago; but Nan Tingyi used his plan to uncover the truth and trapped Lu Huainian in the love web he had carefully woven.
"You imprison me in Lan, have you ever thought that one day, this flood will overflow your city?" Lu Huainian stood on the city tower, looking at the armies of the two countries confronting each other below the city, and stroked the dragon pattern on the jade pendant on Nanting Yi's waist with his fingertips. Nan Tingyi grabbed his wrist and pressed him against the cold city wall. The emotion in his eyes was hotter than the flames of war: "I want you to use your body as an anchor to hold down the blue waves forever."
