In a world where modern cities and underground forces are intertwined, Tianhai City is the center of the whirlpool of business and crime, while the overseas "Black Boxing Park" is a place outside the law (controlled by transnational criminal groups, imprisoning people, forcing labor, and selling organs). The protagonist Chu Feng was once the sole heir of the third generation of the Chu family. He took control of the family business "Chu Group" at the age of 25 and was known as the "Business Overlord". However, because of his credulity in trusting the clever girl Su Mei, he became a prisoner and his family was sold to an overseas park. After three years of hard training in prison, he inherited the life-long martial arts and strategy of the world's top master "Old Ghost". After being released from prison, he transformed into a vengeful Shura and overthrew Su Mei's business empire with thunderous means. Then he broke into the tiger's den alone, single-handedly destroyed overseas parks and rescued his loved ones.
