Dear Westerners, I'm Sorry! I'm Here to Cultivate Immortality!

[Another world + Western fantasy + racial struggle + time travel + adventure + copy] Traveling through time and mistakenly entering a Western fantasy world, and turned out to be a fish-man? Isn't this nonsense? However, due to a strange combination of circumstances, he also obtained the inheritance of cultivating immortals. Hahaha! All mages, warriors, warlocks, shamans, druids, and paladins, please step aside! Elves, dwarves, orcs, undead, goblins, werewolves, all of them are not enough!
