The protagonist, Li Hao, is originally the son of a martial arts master, but because his vitality has always been below the first-level standard, he failed the martial arts exam for three consecutive years and became a "waste" ridiculed by the whole city. After his father disappeared, he and his elderly mother depended on each other, struggling to survive amidst the contempt of others and the pressure of the family. In an accident, the martial arts classics left behind by his father were stained with his blood, which activated the dormant family bloodline. Li Hao instantly broke through to the early stage of the second level, and started the road to change his destiny against the odds.
The heroine Lin Yuwei is the daughter of the Lin family, a well-known martial arts family in Jiangcheng. She is extremely talented and has reached the middle stage of the third rank at the age of eighteen. She is recognized as a genius in martial arts. She is kind and upright, and has always been kind to Li Hao. She not only helped him resolve crises many times (such as fighting against the Zhang family's troubles), but also provided him with training resources, introduced him to the secret realm of mist, and became Li Hao's important partner and bond on the road to martial arts.
