Shen Mo, the former genius of the Shen family of Lingyun Mansion, had his spiritual roots taken away and became a gloomy and lonely useless person, struggling to survive in the dirtiest corner of the family. Once when he was about to die, a mysterious inkstone awakened in his body, and he was able to glimpse the last memory fragments of the deceased. Using this strange ability, Shen Mo pieced together the truth from clues, only to discover that his father's "accidental" death was closely connected to a huge conspiracy that swept the family and the ancient sect. The former uncle's kind face hid greed, the respected senior brother was actually the traitor of the sect, and the entire family was just a sacrifice on the conspiracy chessboard to be slaughtered. In the web woven by countless lies and murderous intentions, Shen Mo used his body as bait and held ink as a blade. When the darkness swallows everything, what he plans is not only revenge, but also a desperate sacrifice to burn himself into the abyss, just to pry a glimmer of light for the people he cares about in a dead situation.
