Luo Moyuan, an ordinary college student who is full of arrogance, accidentally awakens the "Ruffian Nemesis System" one day - as long as he defeats the gangsters, he can get rewards. He originally thought that Lu Yi would spend his life in fighting, but he did not expect that the underground forces in this city were far more complicated than imagined. From street gangsters to underground emperors, from petty quarrels to shocking conspiracies, Luo Moyuan discovered that behind the city's gangsters, there was actually a supernatural force that spanned modernity and fantasy. When the system's rewards became more and more outrageous, when the identity of the enemy became more and more bizarre, and when he unknowingly became the underground king of the city, Luo Moyuan realized that he had created a world by fighting ruffians.
