Swinging the Sword a Million Times, My Mortal Bone Sword Opens the Gate of Heaven

Wulinggen waste material? I sharpened my sword a million times, and the mortal bone sword opened the gate of heaven! He activates the ancestral sword-sharpening stone with his useless talent of five spiritual roots, hones his swordsmanship by swinging the sword thousands of times day after day, counterattacks step by step from the sect's handyman, kills his enemies, breaks the iron law of "spiritual roots determine life" in the world of immortality, and finally uses his mortal body to open the Ascension Gate that has been blocked by the upper world for millions of years, and fights for a way for all the world's cultivators to survive.
