In the Prehistoric Times, You Can Practice Cultivation in Both Realms by Sending Yourself to Death.

The soul accidentally traveled to a parallel prehistoric world. Not long after the sky was opened, ferocious beasts were raging, innate gods and demons were fighting endlessly, and the protagonist, who was physically weak, was struggling. Fortunately, he was born with the precious treasure Wandering Leaf, which gave him the magical power to travel between two worlds, so he could go to a different world where there was no dispute and practice with peace of mind. The Wandering Leaf has its own iron law: no matter which realm the body dies, it will be forced to return to the original body. All cultivation and skills will be retained, and the physical state will be reset as before. Others were cautious and cautious when entering the wilderness, avoiding death in order to survive, but he was not afraid of danger, and he had a way out even if he faced danger with his own body. From then on, the protagonist embarks on a path of spiritual practice in two realms. He retreats in another world to settle down, polish his foundation, and deduce the avenue; he travels in the ancient world to hunt for treasures, compete for innate spiritual materials and spiritual treasures, and face the catastrophe of heaven and earth. He took risks time and time again, accumulated endless knowledge through the cycle of life and death, and became stronger step by step by going back and forth between the two realms. However, as his cultivation becomes more and more advanced, he faintly realizes that there is something strange hidden in the stable world, and there are unknown secrets hidden behind the wandering leaves. In the chaotic world where all races are coming together, he will take the opportunity of two worlds and find a smooth path to enlightenment that is unique to him.
