Useless Spiritual Root? I Deduced the Eternal Magic in Reverse

Su Qingxuan traveled through the world of immortality and awakened the secular spiritual roots of what was recognized as a loser. It was difficult for spiritual energy to enter the body, and he could not practice any orthodox techniques. He was reduced to the humblest outer disciple in the sect, and was subjected to all the looks and ridicule from his fellow disciples. Everyone concluded that he would never be destined for immortality in his life. When he was desperate, he accidentally activated the hidden ability of his spiritual root: if he touched any immortal cultivation technique or magic weapon inheritance, he could reversely disassemble the origin and restore the complete version of the lost ancient immortal technique. The sect's incomplete basic breathing skills were deduced by him into Hongmeng's ancient fundamental skills; the golden elixir sword techniques that the geniuses competed for were optimized by him and turned into ancient swordsmanship skills that can kill all the world; even the top celestial skills in the secret palaces of the major holy places can be filled in and upgraded in his hands. The existing immortal arts that the world has practiced for thousands of years are just incomplete fragments left over from ancient civilizations. Su Qingxuan used his useless body to rewrite the rules of cultivating immortals in reverse, defeating the sect's pride, tearing down the monopoly barriers of the Holy Land, and gradually uncovering the dusty truth about the lost immortality. While a group of immortal emperors were still struggling to practice with incomplete skills, he had already grasped the most original and supreme avenue of the world of immortality and redefined the entire path of immortality.
