In Qingshi Town shrouded in twilight, a lonely young man, A Liang, makes a living by chopping firewood and carrying water. He has a dream of a sword fairy who wields a sword in the rivers and lakes. Only by drawing a sword with charcoal on a bluestone slab can he soothe his obsession. One day, Li Laosan, the second master of Heifeng Village, joined hands to occupy the ruined temple and bully the neighbors. Although A Liang was single and weak, he still stepped forward resolutely. At the critical moment, green light burst out from his palms, and his natural talent for sword bones was unexpectedly awakened, shocking everyone.
Li Laosan saw that A Liang was a prodigy in sword training, and wanted to coerce him to submit due to the safety of his neighbors. Just when A Liang was in a dilemma, the white-haired old man guarding the temple suddenly appeared, using his profound cultivation skills to repel the evildoers and resolve the crisis. After learning that A Liang was born with sword bones, the old man accepted him as his disciple and taught him the true meaning of swordsmanship. From then on, the ordinary young people in Qingshi Town bid farewell to their meager livelihoods and embarked on a journey of swordsmanship based on their integrity and sword bones. Disputes and secrets in the distance were quietly brewing in the twilight mountains.
