Compared to Family Blood, Huh! I've Never Been Afraid of Anyone

If history was rewritten from the Sui Dynasty, the imperial examination system was not invented, and the aristocratic families continued to this day, then where would your family rank? The protagonist travels to a world where his ancestors are summoned by his family's bloodline. He has a system that can go back in time and change his ancestors, and finally successfully leads his family to the top of the world. This novel and its characters are purely fictitious.
