Lu Meng, a retired special forces soldier, was once a sharp sword for the country, but sadly left the military camp for some reason. In order to save the orphans of his seriously ill comrades, he stepped into a lawless place - an underground black boxing ring. When his iron will was combined with his life-and-death fighting skills, he accidentally activated the mysterious "Fighting Mastery" system. Boxing skills, leg skills, joint skills... All kinds of fighting skills in the world have no secrets in his eyes. From the first bloody battle, Lu Meng was like an awakened tiger, tearing apart all his opponents with overwhelming force and killing everyone in the field. His goal is not only money, but also to establish his own iron-blooded order in this sinful soil. Above the boxing ring, he is the invincible overlord; below the boxing ring, a new underground dynasty is being hammered into shape inch by inch with his fists.
