In a world where music can connect heaven and earth and activate the power of nature, the soul of the piano is stained with blood on the battlefield and the strings of the piano are broken in order to protect the heart of his sister. Carrying her sister's broken piano and endless grief, Qin Xin wandered to the valley where her sister died. In desperate situation, she used her own hair as a string to resume the broken piano. When the war resumed, the enemy's iron hooves once again trampled the scorched earth, and the heart of the piano, which was unable to retreat, played the strings with ten blood-stained fingers. The sad sound of the piano actually caused the silent earth to roar, the mountains collapsed and the ground cracked, thousands of armies retreated, and the lingering sound lasted for three days. However, the hair string broke, all ten fingers were injured, and the backlash of power came quietly. In the dissipating reverberation and the trembling depths of the earth, Qin Xin sensed the familiar and eternal soul rhythm of her sister Qin Po. An elegy of protection and sacrifice, destruction and rebirth, echoed throughout the heaven and earth for a long time.
