During the Jinghe period of the Great Wei Dynasty, Xiao Yanchen (28 years old), the cold regent, wore half a mutton-fat jade pendant engraved with the word "Cheng" on his waist. It was a deathbed token of the late Zhenbei General Gu Chengxiao. His younger brother Gu Chengyu (18 years old) is a playboy on the surface, but he is actually very sharp. He always looks like a little thorny beast in front of Xiao Yanchen, but he doesn't know that the other person's gaze has already entangled the snow particles in his hair. On a snowy night seven years ago, Xiao Yanchen brought his younger brother back from northern Xinjiang and engraved "Protect him for the rest of his life" into his bones and blood. There are portraits of the boy from childhood to adulthood hidden in the secret room, and each signature has an exclusive star pattern.
When Gu Chengyu traced the truth behind his brother's death in battle, he found that Xiao Yanchen's jade pendant fit perfectly with half of his sachet, and the crane-shaped waistband was engraved with the word "Yu". On a snowy night, we admired the glazed lanterns together and practiced crane shadow spears together in the school grounds. The trembling of the hairpins on our fingertips and the warmth of our palms gradually peeled away the cold appearance. When the Northern Xinjiang military pay case brought out the Queen Mother's conspiracy, when the blood-drawn road map of his brother in the secret room came to light, and when Xiao Yanchen was covered in bruises while trying to protect him, Gu Chengyu finally kissed the corner of his lips: "I want you to be my destination."
The jade pendant with the crane pattern, the silver crane whistle, and the twin swords of the crane connect destiny, and the two cranes flap their wings to cut through the fog. From the intrigues in the capital to the wind and snow in northern Xinjiang, the names of "Chengyu" and "Yanchen" were finally engraved on the same ultimatum, and they swore that "the cranes and strategies share the same brilliance, and life and death are shared" - this time, they are not guarding others, but returning home to each other.
