Linn traveled to the sea era where pirates were rampant, and at the beginning he became the most useless fisherman in the fishing village.
He owes money, his ship is broken, the whole village laughs at him, and the bully pirates force him to pay back the money within three days, otherwise he will be thrown to feed the Neptune species.
In a desperate situation, he went to sea, the broken ship capsized, and Lin En sank into the deep sea.
Just as he was about to drown, he heard the sound of a school of fish.
"Get out of the way! There are rocks on the left!"
"That big fish is worth a lot of money!"
"The pirate ship behind has drawn its sword!"
From then on, Lin En relied on listening to the schools of fish to catch fish, listening to the voices of merchants to sell at high prices, and killing pirates by listening to the trajectory of the blade.
Fishing can make you rich, and getting rich can make you stronger.
Pirates coming to rob? A punch that sinks.
The navy comes to investigate? Lynn pointed at the boat full of tuna: "Sir, I'm a law-abiding fisherman."
Until one day, an ancient whisper came from the deep sea:
"He who can hear the voices of all things... Come and reveal the true secrets of this sea."
Only then did Lin realize that what he heard was not just schools of fish.
