Shuttle Between Two Worlds: Guangwu County Half a Century Ago

A modern person, after being bound to the system, can travel back and forth between modern times (main world) and fifty years ago (auxiliary world) at will. Time flows synchronously in the two worlds. At first he thought he could always "see fifty years ahead" of people in the sub-world. Soon he discovered that the vice world was a parallel world. From the moment he appeared, the butterfly effect began to spread. At the beginning, although he relied on the information gap and material advantages brought by the system to quickly gather a group of followers, he knew that the advantage of being a "prophet" was accelerating. He can no longer stop in the vice world, so many people's expectations are weighing on him. You have to make progress even if you don't want to, it's not up to him.
