Searching for the Source of Dreams

The protagonist, Xu Qingzhou, had an ancient dream for more than ten years, and then returned to real life with an ancient item. Then, through this item, he started the road to rebirth, discovered the truth and connection between the dream world and the real world, and discovered his golden finger (which can travel infinitely through various worlds). The protagonist regarded each world as a real life, not a copy of the game, and experienced it seriously. Finally, he came to the original world, discovered the truth about the creation of multiple worlds, and started a journey to save all worlds.
