There is no system, and it is not time travel. He was originally a mortal, but he stepped into the path of cultivating immortals by chance. From building the foundation elixir to transforming the Nascent Soul into a god, every step is full of hardships. When building the foundation, you work steadily, just like building the foundation of a tall building; during the golden elixir stage, the light is inherent, and the power begins to show; when the Nascent Soul is formed, it is like a new life; when you transform into a god, you realize the truth of heaven and earth. He overcame obstacles on this road, constantly moving towards the highest realm, and writing his own legend.
