Lu Chen and Ye Qinghan were originally "marginal people" in Canglan City - he was a former sect genius whose martial arts meridians were damaged. He made a living by moving bricks on the construction site and could not even fully perform basic boxing skills; she was an apprentice in a Chinese medicine shop who was judged to be "difficult to enter martial arts in life". In a city where dark warriors were rampant, she could only survive under the protection of the martial arts association.
Until the black martial arts energy wave enveloped the whole city, the S-class dark warrior "Shadow Evil" broke through the protective barrier. When he was about to die, the silent "Hunyuan Martial Vein" in Lu Chen's body suddenly awakened, and smashed the dark warrior's body-protecting energy with one punch; Ye Qinghan held the ancestral "Qingxuan Jade Pendant", awakened the healing martial arts, and dispersed the diffuse dark energy wave with one palm.
The former "abandoned son" counterattacked overnight, only to discover that there was a bigger conspiracy behind Qi Lang: there was a dark martial arts altar buried underground in Canglan City, and even the top brass of the martial arts association were secretly feeding dark creatures with human martial arts essence! "Use my Hunyuan to break the darkness, and I will use you to heal and protect the common people!" The two of them embarked on the road to protect the city side by side, from slaying demons on the streets to going deep into the martial arts world, tearing apart the darkness with the power of martial arts, and finally became the "Two Martial Saints of the City" known to everyone in Canglan City!
