Wenwan Emperor

The protagonist "Ma Ma" is a young toy dealer and a third-generation Chinese medicine family. He accidentally falls into a manhole cover and travels to a different world: an abandoned mine cave in the apocalypse. People in the cave live a simple and boring life. They don't need to eat and only rely on energy stones to replenish their life energy. Immediately after his soul traveled to another world, he discovered that he had the special ability to make, create, and improve the level of energy stones. He lived, studied, and explored in a different world, enjoying the magical experience of the Pegasus starry sky that he had never experienced in his previous life. He used Wenwan's superpowers and superb wisdom to lead the people in the abandoned mine back to the surface, and became the leader of the other world: Wenwan the Great Emperor.
