Return to the Ruins Indefinitely

Gu Chen traveled to the prehistoric continent for sixteen years, but was scorned because of his "waste spirit root" that had all five elements, and his cultivation was stuck at the third level of Qi refining, making it difficult to make progress. His only advantage is the modern knowledge he gained as a science and engineering student in his previous life - mathematics, physics, cryptography, and the way of thinking that requires asking "why" in everything. When everyone told him that "this is how Kung Fu is practiced," he was thinking: "What is the essence of spiritual energy? Is spiritual root a talent or a shackle? What is the underlying logic of the entire cultivation system?" In an accidental treasure hunt, he obtained the relics of a fallen Da Luo Jinxian - a ring that carried a lifetime of memories, and a volume of encrypted animal skin that no one could decipher. The powerful man known as the "Crazy Taoist" spent three thousand years doing a crazy thing: using cryptography to encrypt and using laws as codes, he wrote a set of techniques that could subvert the entire world of immortality - "Hunyuan Jue". There is only one sentence at the core of this set of exercises: Spiritual roots are nothing but shackles imposed by heaven on all spirits. From then on, a good-for-nothing young man at the third level of Qi refining embarked on the journey of dismantling the laws of heaven and earth.
