Reincarnated as a good-for-nothing, Ren Mingwei uses a black cube in his sea of consciousness, burning his lifespan as fuel to strengthen the only sword technique he knows.
While others fight over secret manuals and seek enlightenment in divine abilities, he sticks doggedly to a single book, Sword Art of the Wind-Slaying, training its ordinary moves until they can split open the heavens.
He trades his years for a sharper edge and breaks a myriad of arts with a single sword. From refugee in Qingtian Town to a swordsman whose power reigns for five hundred years, when the Gate of Heaven opens, he burns through the last of his life and finally returns home with his sword in hand.
