A Journey Through One Piece Starting from Elden Ring

So our protagonist is not a traveler from the earth, but an indigenous traveler from the pirate world?

There is a bit of timing logic issue. Hormones are not necessarily the prize of the Valley of the Gods. In fact, Ka Er has eaten the fruit of the Valley of the Gods before. When the manga was updated, a mistake was made and the later single volume was changed to give the fruit to the eldest son, the Blue Dragon. Moreover, at the beginning, Garin did not know that the Valley of the Gods was the hometown of Rocks, and that the navy was only used as a peripheral guard. It was Ginny and the others who leaked the news in advance, so that the Rocks group and other pirate groups knew the news.

I want to read a Pirates fanfic, but I have only heard of Elden's Ring but not understood it. So when I read this book, I have no idea about the level of the protagonist's various abilities and how they will perform. . . Compared to the popularity of Pirates, Elden's Ring is really unpopular. Adding unpopular plug-ins to popular fandoms, plus the author assumes that readers are familiar with Elden and has no ability to comment on it. This is to forcefully write a popular fanfic into an unpopular fanfic. It feels like the author is enjoying himself.

Could the author not be able to tell whether the protagonist has traveled to the world of Laotouhuan or to the game world of Laotouhuan?

Something as important as the big rune was handed over at the beginning😥
