Captain of the Pirates: My Fleet's Limitless Upgrading

Leo accidentally travels to a world full of different races, where magic is everywhere and it's the age of great seafaring.

He doesn't have any fighting talent, and he doesn't have any magic talent, but he can see hint messages, and he has knowledge from his past life.

He decides to give this world a little shock.

Barbarian: “Leo is our god. He brought us food and hope.”

Orc: “Leo is a demon. His ship has a magic tower that shoots fire and calls lightning. It blew up our chief, and he has a whole ship full of those magic towers!”

Elf King: “Leo is a friend of our elf race. I am willing to marry my daughter to him.”

Demon King: “Lord Leo, I am willing to give you the Elixir of Immortality, just to get your protection.”

King Lote: “No empire dares to look at me. My daughter is a servant on Lord Leo's ship.”

...

On the endless sea, there are many stories about Leo.

Some say he is the God of Light, bringing seeds and hope.

Some say he is the savior, killing dragons and punishing bad guys.

Others say he is a demon, a death god. A small orc island was completely destroyed by his fire, just because they killed one of his crew members.
