Su Changsheng was born a mortal without spiritual roots, originating from a bitter and cold mountain village, suffering all the world's cold gazes and humiliation. His grandfather exhausted half his life to beg for an introductory elixir for him, yet still could not change this ordinary destiny. Knocking on the immortal gate and being rejected, everyone in the world says mortals find it hard to tread the immortal path, but he refuses to believe in fate. Under a chance encounter, he obtained the inheritance of an ancient sword immortal, questioning the sword dao with his flesh-and-blood mortal body, sharpening his sword heart amidst snowstorms, humiliation, and life-and-death bloody battles. Ahead are sect barriers, demonic chaos, and the estrangement between immortals and mortals; he does not have endowed talent, relying only on a stubborn tenacity that refuses to submit, wielding his sword to walk against the mortal world. Mortals also have a path ahead, the original heart is the dao. Behold how a mere mortal breaks through heavenly destiny.
