The Endless Journey Across the Three Realms

The alien civilization placed the experimental subjects into a fragment of Earth's history. The experimental subjects learned the Earth's cultivation methods, but lost their memory. In the process of tracing his origin, the experimental subject fought against alien civilization to protect the remnants of the earth, but he became increasingly confused about his origin. The human world, the spiritual world, and the universe are intertwined narratives. (Cultivation, science fiction, passion, growth, darkness)
