The silver bell around the neck of Nanzhao's princess Yin Ling Yuan holds the secret of killing gods. On the night of the fall of the country, the old enemy Ye Zhengming came out of the snow and said: "Little girl, let me teach you a song." Thousands of years of reincarnation revealed the bloody truth: the sound of the piano in the ruined temple is a forbidden technique that cuts off time and space, and the heart-gouging Gu is the key to the building of the God-killing platform. When Ling Gu awakened and tore apart the Nine Heavens, she discovered that she had killed her master a thousand times, all of which were blood-stained rituals in the game between gods and demons. ——The sound pattern is the blade, and reincarnation is the tactic. This forbidden love has written the story of life and death as early as the first encounter.
