Unfinished Business

The collective souls of people from different eras and regions travel to different times in the same world. Everyone in this world is a time traveler. (Except their descendants.) Technological gaps formed in various regions of the world, and slave owners, feudal lords and capitalists jointly formed monopolies. Some parts are pseudo-sci-fi with fantasy elements. The protagonist gradually grows up, devotes himself to and participates in the revolution. Write slowly, revise slowly, and everyone who is interested can read it slowly. If you have any ideas, please comment and I will reply. I would like to have a work of my own.
