This Admiral Is More Like a Pirate

In the era of great pirates, the sea was turbulent and the strong ones destroyed the world and fought each other. And Jonny Jonathan, who came from time-travel and lived for more than 20 years, just wanted to live out his life safely. Until he rescued a green algae head because he couldn't stand the behavior of his superiors.
