Lin Yue, a visitor from the modern world, transmigrates to another realm where martial arts flourish. Through a twist of fate, he joins the Qingmu Sect, where he also gains the ancient legacy, the Azure Void Sword Manual, and the guidance of Elder Yao. After distinguishing himself in the entrance examination, he earns access to the Scripture Repository, only to be ambushed outside by assassins from the Black Garb Hall. It is his first taste of the jianghu's dangers. He devotes himself to cultivation, combining the techniques of this world with his knowledge of the body's meridians to break through from the Body Tempering Realm to the Qi Refining Realm and greatly increase his strength. But trouble soon resurfaces. The Black Garb Hall conspires with Elder Sun of the sect, hoping to eliminate him during the qualifiers for the sect tournament and suppress both him and Elder Yao. His opponent is Jiang Chen, a ruthless enemy in the mid-stage of Qi Refining, while elders lie in wait to attack him from the shadows. Unfazed in the face of danger, Lin Yue refines antidote pills to resist poison, wears a heart-protecting jade to guard against hidden attacks, and channels Qi Refining energy into his Azure Void Swordsmanship, turning the tables to win before a vast audience. The sect's schemes are far from over, and an even greater force lurks behind the Black Garb Hall. Elder Yao's old grudges are tied to secrets of the past. Wielding a rusty iron sword, Lin Yue hones his swordsmanship and advances his cultivation while navigating sect rivalries and the jianghu's shadowy conflicts. With an ordinary man's body, he steadily advances along the path of martial arts in this new world, his sword aimed at ever greater heights.
