Chen Fan and Luo Li were ordinary ordinary people in Donghai City - he was a "pulseless apprentice" who worked in a martial arts gym and could not even practice basic boxing skills; she was an ordinary student who was judged to be "difficult to enter martial arts in life". In a city where alien beasts and warriors were rampant, they could only survive in a safe zone.
Until late at night, a bloody alarm pierced the night sky, and the A-level alien beast "Earth Splitting Rhinoceros" broke through the protective shield. When he was about to die, Chen Fan accidentally awakened his ancestral "Dragon-shaped Fist" inheritance and shattered the scales of the alien beast with one punch; Luo Li activated the jade pendant he carried with him, unlocked the "Ice Sword Intention", and froze the battlefield a hundred meters away with one sword.
The former "marginal man" counterattacked overnight, only to discover that behind the tide of alien beasts was the conspiracy of the Warriors Alliance - the top brass was secretly cultivating evil alien weapons! "With my fists, I will defeat all enemies, and with your sword, I will defend this lonely city!" The two embarked on the urban martial arts journey side by side, from fighting on the streets to guarding the defense line, splitting the darkness with their fists and blades, and finally became the most reassuring "martial arts twins" in Donghai City!
