With the rise of global martial arts, foreign forces covet the resources and order of Chinese martial arts and frequently send masters to infiltrate. Liu Feng, who has received rigorous martial arts training since childhood, has the ambition to protect his family and country, and he sticks to it silently in the shadows of the city. In an unexpected conflict, he used his superb martial arts to defeat top overseas warriors, and his powerful strength alarmed the Chinese Martial Arts Alliance. After being invited to join the Guardian camp, Liu Feng fought side by side with his teammates, tracking down foreign power bases in the reinforced jungle, guarding the secret realm of martial arts, and rescuing captive people. After countless life-and-death battles, he broke through the shackles of martial arts and transformed from a rising star into a Chinese martial sage who terrified foreign enemies. He used his iron fist to build China's defense line so that foreign forces would no longer dare to cross the border.
