The Most Powerful God Who Controls the Sea

When I traveled to the world of pirates, I had the River God System... The River God with the golden ax and the silver axe. I originally thought I was going to cool off, but the system told me that hundreds of rivers converge into the sea, and the sea is also... A river? "So, lovely Luffy, did you drop this golden Nami, silver Nami or this ordinary Nami?" "Lovely Charlotte Lingling, did you drop this golden devil fruit, silver devil fruit or this ordinary devil fruit?" "Dear Akainu, did you drop a gold self, a silver self, or an ordinary self?" Akainu: "Don't touch me, you devil!" This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
