Fishing to Raise Sea Monsters, I Became a Tyrant of the Deep Sea

I drew a level 58 magic skill. Unfortunately, my profession is sailor, so I can't use it. They said that I was the most useless newcomer in the entire server. Later, I came back in a living giant ship that could eat up cities. They asked: Have you unlocked that level 58 skill? I picked up the long-handled ax and waved it gently towards the sea. A thousand-meter-deep trench appeared in front of everyone. "You just unlocked it, do you want to see the effect?"
