I Have Already Achieved Hunyuan, but My Classmates Are Just Yuanying?

Thousands of years ago, prehistoric times came, and the world entered the era of immortality. The Earth Immortal is the top, and the ten immortal sects dominate. Everyone regards the "Earth Immortal" as the end of their cultivation. On the awakening day of his senior year in high school, Lin Fan was tested to have low-grade mortal spiritual roots. However, his childhood sweetheart Chu Xinyue had high-grade heavenly spiritual roots and was accepted as a saint by the most powerful immortal sect. The whole world is envious of his "one step to the top". No one knows, he is just a drug introduction. Chu Xinyue personally took away his heart's blood, destroyed his spiritual roots, and threw him into the Island of No Return, known as "There is no return," to wait for death. But Lin Fan smiled. In this world, there is no "Feng Shen Yan Yi" or "Journey to the West". No one knows who San Xiao is, no one knows Jie Jiao Chan Jiao, and no one knows that Earth Immortals are just ants. But he knows. Wugui Island is the Island of Three Immortals, and it is the dojo where empress Sanxiao was taught. The spiritual root is broken? Repair from scratch. Is your cultivation gone? He holds an entire volume of ancient scripts. From Zhao Gongming, the direct disciple of Tongtian Cult Leader, to the catastrophic disaster in the future of Jie Cult - he worked step by step and changed his destiny against the will of heaven. Some years later, At that time, my classmates were still struggling with forming elixirs. Lin Fan stepped on the World-Destroying Black Lotus, protected by the Eastern Emperor Bell, and accompanied by the Four Immortal Execution Swords. Behind him stood the disciples of the Jiejiao Sect, looking at his former classmates—— "I have already attained the Hunyuan Realm. Old classmates, how come you are still Yuanying!?" Under the saints, all are ants. And I want to be the one who stands at the top.
