Kaido Doesn't Respect Martial Ethics and Attacked My 96-Year-Old Navy Veteran Secretly.

My name is Rod, I am 96 years old. About 90 years ago, I accidentally came to the world of pirates and brought a system with me. This is a perfect protagonist template. In previous decades, I stole the show like a god of war. He fought Rocks, taught Garp Sengoku, taught Roger Reli a lesson, and even used Kaido as his mount for a while. But now I am tired of this kind of life and want to travel around and return to ordinary life. Who would have known that Kaido, a kid with no moral integrity, would sneak attack on my 96-year-old man today. I just want to give this guy a word: Mouse Tail Juice!
