Lin Fu, a handyman of the Tianjian Sect, was accused of not having the aptitude for swordsmanship because of his miscellaneous spiritual roots. He was bullied for three years. An accidental accident found the incomplete "Thirteen Styles of the Mortal Sword". Based on the mortal body polished by chopping wood and carrying water, he perfected the sword moves with wisdom. He defeated all the heroes in the handyman competition, broke through the qualification barrier and was promoted to the outer sect, used mortal iron as a blade and his body as a front, fought against powerful enemies along the way, and finally became the first mortal sword emperor in history, dominating an entire world.
