Kokubu Prison, a living hell in 2001. In order to avenge the tragic death of his girlfriend Yingying, King Heli killed a drug dealer and was thrown into this privately contracted prison of crime. In prison, the deputy warden Single-Eyed Snake colluded with the kings of the four warehouses in the East, West and South to use the prisoners as fish and meat, and even secretly planted opium poppies to make huge profits. Li Wang, who possesses the unique skills of hard qigong, is not used to the lynx bullying the weak, so he takes action to stop his evil deeds, but this also leads to a fatal confrontation with Beicang Tianwang A Hai. From blowing up Ahai's skull to burning the poppy fields to anger the warden, King Li gradually tore apart the dark veil of the prison. When the prison warden, who is also a master of hard qigong and can transform into a giant monster, shows his fangs, this resistance at the cost of flesh and blood will eventually end in a frenzy of breaking down the prison walls and releasing all the trapped people - the fist of King Li is the only justice here.
