In the late Southern Song Dynasty, Mongolia gradually invaded the Central Plains with the intention of unifying the world. Suddenly, an ancient painting from the Spring and Autumn Period that had disappeared for hundreds of years appeared in the world. Legend has it that if you get this painting and follow the instructions in the painting to find the Liangqin in the painting to unlock the secret, you can dominate the martial arts world and unify the world. Heroes from all over the country competed for the piano and the painting, causing a bloody storm. The dust finally settled after a seizure of the painting in the snowy mountains. However, twenty years later, a Tubo shepherd girl accidentally returned to the Central Plains and discovered that the mystery of her own life experience was closely related to the painting and the harp. It was also discovered that the painting from that year was a fake, and the whereabouts of the original work and the raoliang harp were still unknown, and the world was once again in turmoil.
