"Shocking!! A legendary king fish has appeared! Fishing master Teacher Ma hooked a thousand-pound monster with one cast, and a mysterious tycoon bought it for an astronomical price! A miraculous longevity meat was carved from the fish, restoring the eater to the prime of their youth and bringing their vigor back!"
"The craziest story yet: a young man drifted at sea for a day and a night, only to catch a stunning mermaid girl! The mermaid has now become a registered citizen and married him!"
"Latest news: A delivery rider for a certain food-delivery company was passing under a bridge when he noticed the water was crystal clear. He casually cast a line and unexpectedly mastered the art of fishing. From then on, he was master of his own fate!"
Three years ago, a comet carrying a mysterious virus passed by Earth. The virus awakened the fish, setting them on a path of frenzied evolution.
In no time, waters around the world fell to the fish. Anglers, once seen as mere hobbyists, suddenly became elite members of society with a rare and valued profession.
Then, as Qin Ming lay in a hospital bed with only a month left to live, a mechanical voice suddenly rang in his ear.
[Ding! The Strongest Angler System has activated!]
[Each fish caught: +1 hour of lifespan]
[Constitution +0.1]
[Breathing technique unlocked: Yin-Yang Breathing Technique: Endless Vitality, Persuade the "Fish" with Reason]
From then on, with rebar in his left hand and an aircraft carrier's arresting cable in his right, he took on pay-to-fish ponds, reservoirs, the Heavenly Lake of Changbai Mountain, and the legendary water monsters.
The plot is quite rich, I guess.
Keep it up! Hopefully, it won't stop updating like those fishing stories I read before.
