The Mystic Lunar Dance Troupe took in Jin Sohan as an orphan, and he spent his childhood with them. But one day, one of the four great demons, the Venom Demon, discovered that he was special and kidnapped him. After all kinds of tests, he decided to raise him as his disciple. Ten years later, Jin Sohan tried to look for traces of the Mystic Lunar Dance Troupe, but the Sword Dance Troupe had already been destroyed at the hands of the Unorthodox Faction that’s now ruling over his hometown.

Kidnapped as a child to be trained in the art of poison, Sohan Jin returns to his hometown in search of the group of New Moon Sword Dancers who raised him. However, upon his return, Sohan discovers the sword dancers have been defeated by a nefarious sect that now rules the area, with some members having been abducted. What would have been a heartwarming reunion transforms into a quest for revenge as Sohan begins his search for the remaining sword dancers, and he’s willing to poison anyone who gets in his way.
