An everlasting song that began in the setting sun at the end of the Tang Dynasty and fell in the snow in Bianliang.
He came from a thousand years ago, traveled through the wars of five generations, was used to seeing the bones of troubled times, and accompanied a generation of heroes to create a century-old foundation for the Song Dynasty.
On a snowy night, he kept his promise and died, single-handedly welding the last gate to the troubled times of the Five Dynasties.
The snow in Bianliang has fallen for thousands of years, and history books have erased all traces of him. Only that jade pendant, guarding the agreement between him and her, has been waiting for him all his life.
This time, when he returned from walking in the snow, he not only wanted to protect these thousands of miles of rivers and mountains, but also wanted to protect his old friends who were full of heart.
