Tales of dark river (Legend of Assassin)

Summary:
Dark River is the most mysterious assassin organization in the martial world, composed of the Su, Xie, and Mu families, with the three families’ leaders known as the “Big Family Elders.” The Big Family Elders have been afflicted with a strange poison, putting their lives in imminent danger. Upon learning this news, the three forces within Dark River seize the opportunity to launch a rebellion. Su Muyu, as the leader of the Big Family Elders’ bodyguard team “Spider Shadow,” seeks the help of the divine doctor Bai Hehuai from the Medicine King Valley to treat the Big Family Elders while simultaneously repelling assassins sent by the other families to protect the Elders. At this time, his good friend in Dark River, Su Changhe, represents the Su family in joining the action to assassinate the Big Family Elders.
