During the Zhenyuan period of the Tang Dynasty, there was a turmoil in the southwest border. Shunanda, the prince of Piao, led the orchestra to Chang'an to perform music, but he didn't know that this trip had already been coveted by various forces. In this chaos, a young swordsman named Chen Huaizhou quietly appeared.
He is the only descendant of Haidonglai, "The sea of blood surges, the Red Emperor comes from the east". He was adopted by this legendary master who was both good and evil since he was a child, and he showed amazing talent in swordsmanship. A Chilan Sword, he learned the truth from Haidong Lai, but he always kept in mind the master's teachings: "A sword is only meant to be used when it's time to use it." When he rescued the lost Tang Dynasty inner guard Guan Ling'er, the trajectory of his fate changed. This innocent girl with a secret involved him in the Pyo Kingdom.
When Master Hai Donglai handed the bloody long sword into my hand, he said: "Your sword is only for the time of use." But I didn't expect that the first time I drew the sword, it was to save Guan Ling'er, the inner guard of the Tang Dynasty who always liked to get lost.
A whirlpool of music. The ferocity of the Evil Pig King, the mysterious doctor in Ruili City, the undercurrent of Nanzhao, and the secretive true intention of Master Hai Donglai all pushed this seemingly peaceful music tour into an unpredictable abyss.
