When the broken sword was reforged, the world regretted it. Jing Zheyue was once a lonely minister with unparalleled swordsmanship. He cut the sky with one sword, but his sword broke and disappeared because of the betrayal of his best friend. Lu Jinhou was a killer whose blood stained the strings of the piano. He cut his soul with a song just to find the real murderer who burned down his master that night. When the broken sword regained its cold glow, the two met again in the Fengxue Ancient Temple - one wanted to destroy the sword to atone for his sins, and the other wanted to borrow the sword for revenge. The sword is not an old sword, the person is not an old friend, but the blood is still warm and the hatred is not cold. There are rumors in the rivers and lakes that if Jing Zhiyue holds the broken sword again, Lu Jinhou will burn his harp to accompany him. This night is not a reunion, but a reckoning.
