When Chen Jing, the last successor of Chen Style Tai Chi, entered the MMA arena where money and hormones intertwined in order to keep her disciple alive, everyone thought it was just a farce to please people. Especially the arrogant Sanda king Lu Feng, who openly mocked her martial arts as an outdated dance. However, when the international double-player mixed competition system forcibly binds them, becoming each other's most irreconcilable "weaknesses", the barriers between the two worlds are completely shattered in every physical fight and run-in. From rivals who despise each other to partners who depend on each other for life and death, together they set off a storm that subverted the global perception of fighting. This is not only a battle in the ring, but also a last-ditch battle to rectify the declining martial arts. When the national anthem is played in the highest hall of a foreign country, they know that the direction of their fists is towards China.
