Mao Xuan, a doctor of physics, was thrown into the chaotic Hongmeng era in a laboratory accident. When he opened his eyes, he saw Pangu holding an ax to open the sky, which was divided into two parts: clear and turbid. He has no cultivation at all and only wears a hospital gown, but he carries modern scientific thinking and a complete memory of myths and history. In this early age when innate gods and demons were everywhere and dangers abounded, he was not as deep-rooted as the Three Pure Ones, nor did he have the innate spiritual treasures to protect him. With a fragment of the Seal of Creation obtained by chance and a foresight of the general trend, Mao Xuan started from scratch and embarked on his own path to enlightenment. From the beginning of chaos to the first tribulation of dragons and phoenixes, from the battle between lich and lich to the romance of the gods, he will do things that defy nature as a mortal, use scientific thinking to analyze the secrets of immortality, and use modern wisdom to compete with the great powers of the ancient world. This is a Hunyuan Avenue that no one has ever walked before - when physics meets the laws of immortality, and the path of heaven meets the butterfly effect, let's see how Mao Xuan walks out his own path to a saint in this magnificent epic!
