The protagonist Chen Rui inherits his brother's blood-stained armband, and takes on the blood feud and unfinished mission. Under Lei Zhen's harsh purgatory temper, amid the ubiquitous difficulties of the "Poisonous Snake", and in the deadly confrontations with the shadow of the "Black Thorn", Chen Rui's blunt blade ignited by hatred has experienced the ultimate tempering of flesh and blood and will. He must learn to remain calm in anger, stick to the bottom line in killing, and transform from a "wolf cub" who only seeks revenge to a "wolf fang" who truly understands the righteousness behind "leave me alone" and shoulders the heavy responsibility of his family and country.
