He is the last descendant of the hidden ancient martial arts sect. He possesses peerless martial arts skills, but he lives in the city due to an accident. In order to find his lost relatives, he changed his name to Feng Yuan and became an ordinary high school student. However, the peaceful campus life has undercurrents - underground forces secretly infiltrate, mysterious organizations covet the secrets of ancient martial arts, and even the classmates around them hide unknown secrets. When gang kidnappings, martial arts challenges, and transnational conspiracies ensue, he has no choice but to take action and crush all enemies with extraordinary force. From a top student on campus to an urban legend, from a quiet and low-key person to a world-famous person, he gradually uncovered the mystery of his life experience and met like-minded partners and confidantes. He wants to protect the city with his fists, and he also wants to use the spirit of martial arts to awaken the kindness and courage in human nature. This is a contest between force and wisdom, an urban legend where blood and warmth coexist.
