My Demon Uncle Taught His Niece to Give Him a Spiral-Ring Bath!

After transmigrating to a parallel world, Chen Heng activates the Ninjutsu Deduction System.

Whenever he teaches someone ninjutsu, he earns deduction points.

His first students are his two adorable six-year-old nieces.

He even comes up with all kinds of new ways to use ninjutsu!

The little girls are playing outside when streamer Zhou Jie happens to see them on a live broadcast.

"That hand sign speed... Did she really make a Water Dragon Bullet?!"

"Wait... they used it to take a shower?!"

"And that Rasengan... to scrub someone's back?!"

"Did your uncle teach you all this?"

Zhou Jie suddenly feels like she's wasted the past twenty-odd years of her life. It turns out ninjutsu really does exist!

"Look! Uncle's back, flying in with Kamui!"
