In 1987, retired special forces Lin Yuan and his comrades Chen Meng and Zhou Wen opened "Brothers Video Games" in Yangcheng, but they were repeatedly blackmailed by gangsters. In the face of oppression, they suppressed their plans, raided underground casinos, and used iron-blooded methods to intimidate Xiao Xiao, gradually annexing surrounding small forces and expanding their industrial territory. As their reputation grew, they aroused the fear of the Qinglong Society, the largest gang in Yangcheng. In the midst of conspiracy calculations and large-scale battles, Lin Yuan was injured many times but became more courageous as he fought, leading his brothers to break through numerous obstacles, eventually overturning the old order and becoming the master of the underground world.
