Hong Kong boxing champion Ajie is willing to pay a fee of 500,000 appearances to protect the master's boxing gym. He fought bravely against the myth of Muay Thai. He suffered a serious injury to his leg and even left a psychological shadow. In order to help Ajie, the master sacrificed himself to challenge Qiu Li, which triggered Ajie to finally overcome his fear and confront Qiu Li again. This is not just a competition, but also a proof of defeating oneself.
