Eighteen years after the decline of Qingshan Sword Pavilion, the abandoned boy Li Youran was raised by the sword masters. He learned the art of swordsmanship in a mortal body, broke through the realm and entered the Taoism. He took the spirit fox down the mountain and got involved in court disputes, rivers and lakes vendettas and the conspiracy of the Underworld Palace. Transformed from an ignorant boy into a strong swordsman, revitalized the Qingshan sword pavilion, conquered the world with one sword, and reached the top of the mountain freely.
