[Adopting Sons System: Everyone Is a Son!]

The protagonist is Whitebeard, who transmigrates from the Blue Star under unusual circumstances.

After dying in the Summit War, Whitebeard opens his eyes and discovers that he isn’t dead after all. Instead, he’s arrived in a new world: the Naruto world!

He awakens the [Old Man System]. All he has to do is adopt sons to become stronger.

Once he becomes the strongest in the Naruto world, he’ll be able to return to the One Piece world through the System.

“Ace, wait for your old man. I’ll save you, no matter what!”

Whitebeard gazes up at the sky, his resolve unwavering as he sets out once more on the path to strength!

However...

There are so many children in this world with tragic fates.

But don’t worry. Your old man will protect you, give you a warm embrace, and shelter you from the storm!
