A flute of unknown origin, whoever gets it will rise to great heights, but whoever loses it will fall into despair. In the Spring and Autumn Period of Jin, there was a 67-year-old clan fratricidal incident, which ended with Quwo Chengshi and his family seizing the orthodoxy. This event became a symbol of the collapse of rituals and music, and the resulting division of the three families into Jin Dynasty also became the beginning of the Warring States Period. This incident seems complicated and unorganized, but if you comb it carefully, it is not difficult to find that the cause of the incident was actually a woman who brought a mysterious ancient flute into the Jin Hou Kingdom. Many years later, no one remembers this incident. The torrent of history has wiped away the grudges of the previous life. However, the curse of the flute has made it impossible for the instigator and the victim to escape from each other in life. And they are not the only ones involved in this vortex. Gradually, they discover that there are other "people" who also have indelible bonds, blending in the vast sea of people, ready to discover and ambush their prey at any time...
