Former Sanda team member Chen Po retired and became an underground boxer, relying on counterfeit boxing to survive. In a match where he was 'slaughtered' by boxing champion Song Zhan, he accidentally saved a life, but awakened his 'second-counting intuition' - he could accurately predict the moment when his opponent would be exhausted. With one kick to shatter Song Zhan's undefeated myth, Chen Po was forced to get involved in a boxing conspiracy controlled by an international gambling group. With the help of reporters Tang Tang, Lao Gui and Bai Ya, he went from the underground black boxing to the top of the world, and his ultimate goal is to defeat the legendary boxing champion Iron Tower, break all myths, and at the same time break his own inner demons.
