He was hit by a car on the day he went to register his marriage, then transmigrated. He’d only wanted to live as a wealthy landowner, but he was swept into one upheaval after another. He was ennobled as a marquis and granted land, built businesses, and led the people in his territory to prosperity. Anyone who dared bully him would have their entire clan wiped out. As chaos engulfed the land, he rode the surging tides of history, maneuvered across the political landscape, and unified the eight corners of the world.
Overall it looks pretty good, and the rhythm is well controlled.
