Me, Whitebeard: Double-Crossing into Naruto Before the Summit War

After transmigrating into the world of One Piece, Whitebeard regained memories of his previous life a little over a month before the Paramount War, while clashing Haki with Shanks. He learned of his tragic fate in the war.

Fortunately,

His God-Tier Son-Adopting System awakened.

From the start, it locked onto the Naruto world, which had plenty of orphans.

He could not only travel freely between worlds, but time in the original world passed at one-tenth the rate of time in the locked world. More importantly, the System gave generous rewards every time he adopted a son.

In an instant,

Whitebeard was overcome with joy.

One son, one reward. There were so many orphans in the Naruto world, such as Orochimaru, Nagato, Yakushi Kabuto, Konan, Tsunade, Naruto, and Sasuke. If he adopted them all as sons, wouldn’t the rewards just keep pouring in?

And so,

Whitebeard traveled back and forth between the two worlds,

giving the orphans of the ninja world a warm home while letting Marco, Ace, and the others witness firsthand their old man Whitebeard living a second life.
