Modern young man Shen Yi accidentally traveled to a parallel world with underworld forces and possessed himself as a gangster.
Shen Yi initially relied on modern knowledge to stand out in gang conflicts, winning prestige and the trust of his subordinates. Later, in the process of expanding his power, he met the kind and gentle Lin Yue, and love quietly grew. At the same time, it also triggered fierce conflicts with Li Xiong and other hostile forces, and the two sides fought many times. After winning a firefight, Shen Yi was hit hard. He decided to change his ways and get involved in legitimate business, but it was difficult. Not only did he have to deal with police investigations and obstruction from other underworld forces, but there were also differences within the gang and faced an internal rebellion crisis. Li Xiong even took the opportunity to unite with other forces in an attempt to defeat him completely. However, Shen Yi relied on his wisdom, the help of his brothers and the support of Lin Yue to fight back in a desperate situation. He finally unified the underworld, completed the cleansing, became a legal entrepreneur, and devoted himself to charity to give back to the society, achieving the transformation from a gangster brother to a righteous businessman.
