Synopsis

After transmigrating to the world of One Piece, Arthur, the youngest officer in the Revolutionary Army, received his final assignment before retirement:

Follow his grandpa Garp and go undercover in the Marines!

But he was only seven years old!

Just as Arthur was about to refuse, he activated a god-tier Frog Pickup System!

He could see glowing orbs of treasure dropped by the strong, each containing various attributes.

The stronger the person, the more powerful the orb they dropped!

To get high-quality treasure orbs, Arthur followed his grandpa Garp!

From the Grand Line all the way to Marine Headquarters!

[Congratulations, Host. Your Devil Power has reached level 30. You have successfully awakened a Devil Fruit!]

Garp: "My grandson's as strong as I am. Shouldn't he be appointed an Admiral?!"

Sengoku: "Arthur, you're the Marines' strongest sword. Stop turning down the Admiral position!"

Shanks: "Without Arthur, the world of swordsmanship would have been shrouded in darkness for all eternity!"

A few years later, Arthur sighed and said:

"Three years undercover, then three more. Boss, I'm the top dog now!"

It's quite enjoyable to read, but the plot gets going a bit slowly. It gets better and better after the island part; I suggest skipping that part if you want to watch it. Once you get into the main story, it's hard to put down. Also, is the author a girl? She writes so cutely.

It's a good book, but there are too many malicious negative reviews. If the author updates frequently, I'll definitely give them a reward. Staying up all night to read it is really worth it! Why are people leaving negative reviews without even reading it? Doesn't that affect the author?

To be fair, those who have read the whole thing, the author's pacing was indeed a bit slow at the beginning, probably to accommodate new readers of One Piece (not everyone has read the original work). Many plot points were written in great detail (perhaps because the author is a woman), so the pacing was intentionally slowed down.

It's so good, I'm not sleeping tonight, I'll watch it all in one go.

I read over 130 chapters in one go. It's really good. The setting of the light orbs and the various golden talents are all very well done. Putting everything else aside, what I got was the mythical beast species Vermilion Bird! I'm looking forward to the protagonist becoming a great general!

Not bad, I'll give it a try.

Keep up the good work, author! It's quite good.

I absolutely have to finish watching this tonight, I can't sleep! Some people might say it's slow, but that's probably to cater to readers who haven't read One Piece. The author tends to explain things that are common knowledge to One Piece fans but quite unfamiliar to those who haven't read the series, such as Haki, various abilities, and characters. However, it doesn't affect the reading experience; the author is quite gentle.

I've saved this to watch slowly, and so far it's been quite good. I don't understand why people are criticizing it, especially those who can't even finish thirty minutes. I've finished reading it. It's a fairly conservative style; the abilities the protagonist gains are all building a foundation for him, not making him invincible from the start.

Well written, but you're in the Navy. Pirates are always evil.
