Which novel's protagonist had such a high martial strength that even the country had to obey him, and his identity was very prominent?

I recommend "The Most Awesome Senior Granduncle in the Heavens". The main character is a transmigrator. Every time he transmigrated to a different world, his seniority would be very high. He is a figure like a senior granduncle or an ancestor. In addition, he has a strong set of skills, so he is awesome! His martial strength was also very high, and he was able to make the country obey him. I hope you like my recommendation. Muah ~
